Transfer taxes, gain, withholding, and prorations

Keep property tax, income tax, transfer tax, and closing allocations separate.

Three gains
Realized, recognized, and deferred gain are different quantities.
Cash
Debt payoff and withholding affect cash without necessarily reducing realized gain.
Two assessment tracks
Proposition 8 temporarily reduces assessed value without replacing the Proposition 13 factored ceiling.

Learning objectives

  • Compute basic gain, documentary transfer tax, and stated prorations.
  • Distinguish exclusions, deferrals, withholding, and reassessment.
  • Explain California property-tax timing and major transfer-related tax rules.
  • Calculate Proposition 13 assessed-value limits and distinguish temporary Proposition 8 reductions from a new base year.

Four different questions

Separate closing cash, income-tax gain, withholding, and property-tax assessment before calculating; similar dollar figures belong to different legal systems.

A sale can raise income tax on gain, recurring property tax and reassessment, documentary transfer tax, and tax withholding. These are different systems. A seller can owe transfer tax even when no taxable income gain is recognized. Withholding can be required even when the final tax will be lower, and a federal gain exclusion does not automatically preserve a California property-tax assessment.

For examination problems, use the stated assumptions and identify which system is being tested before calculating. For a real transaction, tax advice belongs with a qualified tax professional because filing status, history, entity ownership, depreciation, and exceptions can change the result.

Basis and gain

Determine amount realized and adjusted basis from the appropriate records; current debt, assessed value, and market value are not interchangeable substitutes.

Basis is the starting tax investment in the property, commonly cost for a purchase. Adjusted basis incorporates appropriate increases and decreases. Capital improvements can increase basis; depreciation allowed or allowable can decrease it. Ordinary repair costs are not automatically capital improvements merely because the owner paid them before selling.

The basic gain relationship is:

Amount realized minus adjusted basis equals realized gain.

For a simple cash sale, amount realized is generally sale price less qualifying selling expenses. The mortgage payoff affects the cash the seller takes home, but it is not an additional deduction from gain just because escrow pays it. Confusing proceeds with gain is a common mathematical error.

An owner buys for $400,000, makes $50,000 of qualifying capital improvements, and sells for $650,000 with $30,000 of qualifying selling expenses. With no other adjustments, basis is $450,000 and amount realized is $620,000. Realized gain is $170,000. A $200,000 mortgage payoff changes cash proceeds, not that gain calculation.

Recognized gain is the amount currently taken into taxable income after applicable exclusions or deferrals. Gift and inherited property can follow different basis rules; inherited property generally receives a basis tied to date-of-death value or another applicable valuation rule, while gifts commonly involve carryover-basis rules with special loss limitations. Do not assume every transfer resets basis to market value.

Follow the dollars through two different calculations

Suppose an investment property sells for $900,000 with $45,000 of qualifying selling expenses. The seller's adjusted basis is $520,000 and the loan payoff is $350,000. Amount realized is $855,000, producing $335,000 of realized gain before considering a deferral or other applicable rule. Simplified cash proceeds are $505,000 before withholding and other closing adjustments.

The loan balance appears in the cash calculation because proceeds are used to repay the lender. It is absent from the gain calculation because borrowing against the property did not ordinarily create new basis. Refinancing for personal spending can therefore reduce closing cash without reducing taxable gain. A heavily leveraged seller may owe tax even when relatively little cash remains after debt repayment.

Basis also requires records. Qualifying acquisition costs and improvements may increase it, while allowed or allowable depreciation can reduce it. The current loan balance, market value, and assessed value are not substitutes. For a gift, the donor's basis and value at the gift can matter; for inherited property, death-date or other applicable valuation rules can matter. The fact that the deed changes names does not tell you the correct basis rule.

Compare gift and inheritance starting points

Assume the same $200,000 owner's basis and $350,000 value at transfer, followed by a $400,000 sale. Compare two separate transfers with no expenses, depreciation, gift-tax adjustment, or special valuation election:

TransferRecipient's basis in this exampleRealized gain at sale
Gift, with value above the donor's basis$200,000 carryover basis$400,000 - $200,000 = $200,000
Inheritance using date-of-death value$350,000$400,000 - $350,000 = $50,000

Changing only the transfer method changes basis. A gift whose value is below the donor's basis needs the separate gain-and-loss basis rules; do not extend this example to that case.

With an assumed $500,000 adjusted basis, realized gain is $760,000 amount realized minus $500,000 basis = $260,000 before any exclusion or deferral. The loan payoff affects cash, not that gain calculation. Chapter sources

The principal-residence exclusion

Apply ownership, use, and prior-exclusion conditions to qualifying gain, not gross price; a replacement purchase is not generally required for the main-home exclusion.

Federal law may exclude up to $250,000 of qualifying main-home gain, or up to $500,000 for qualifying married taxpayers filing jointly. The usual framework includes ownership and use for two of the preceding five years and limits involving a prior exclusion. The joint-return rules include their own ownership, use, and look-back requirements.

The exclusion concerns gain, not sale price. It is not restricted to taxpayers over a particular age, and qualifying taxpayers need not buy a replacement home to obtain it. Partial exclusions and special rules may apply; depreciation and nonqualified use can limit what is excluded. A personal-residence loss is generally not deductible.

In the $170,000-gain example, a qualifying single owner could potentially exclude the entire gain. That does not mean the sale is exempt from every closing tax or filing requirement. Determine each separately.

Test ownership and use separately

A taxpayer can satisfy the ownership test without satisfying the use test. Owning a vacation property for ten years does not by itself establish two years of qualifying main-home use. Conversely, living in a property as a tenant and later purchasing it can create different ownership and occupancy histories. The applicable tests examine both histories rather than asking only when the taxpayer first moved in.

For the full $500,000 exclusion on a qualifying joint return, generally either spouse must meet the ownership test, both must meet the use test, and neither may be disqualified by a prior exclusion within the look-back period. The tests need not be satisfied by identical facts for each spouse. Other conditions and special rules still apply, including certain periods of nonqualified use and depreciation.

Assume a qualifying single taxpayer realizes $310,000 of gain on the main home and qualifies for the full $250,000 exclusion, with no other adjustments or special rules. The remaining $60,000 is not excluded by that provision. This does not tell you the final tax without applicable rates and the taxpayer's full circumstances. Keep the excluded amount, recognized amount, and resulting tax as separate quantities.

A joint return does not automatically double the exclusion

Spouses file jointly. Assume no automatic disqualification, nonqualified-use allocation or depreciation issue. Who satisfies the tests?

One owner; both residents
One spouse owned for two of the prior five years. Both used the home for that period and meet the two-year look-back rule.The ordinary $500,000 maximum can apply; both spouses need not hold title for two years.
One fails residence
Only one spouse meets the residence test; no partial-exclusion exception is stipulated.The ordinary joint $500,000 test is not met. Evaluate each spouse's eligibility rather than automatically doubling.
Recent prior exclusion
One spouse used the exclusion on another sale less than two years earlier.The look-back condition for the ordinary joint maximum fails; investigate any applicable separate or partial relief.
Fictional eligibility contrasts. The exclusion offsets qualifying gain, not the sales price or loan payoff. Chapter sources

Like-kind exchange deferral

Test exchange eligibility and timing, then distinguish cash boot, recognized gain, and deferred gain; replacement basis preserves rather than erases deferred tax consequences.

Section 1031 can defer qualifying gain on exchanges of real property held for investment or productive use in a trade or business. A personal residence and property held primarily for sale do not qualify merely because they are real estate. The exchange must satisfy its legal requirements rather than operate as an unrestricted sale followed by a later purchase.

In a typical deferred exchange, replacement property must be identified within 45 days, and receipt generally must occur within 180 days or the applicable tax-return deadline, including extensions, if earlier. Receiving cash or other non-like-kind value, often called boot, can trigger recognition of gain.

Deferral is not forgiveness. Basis rules generally carry deferred gain into the replacement investment. A qualified intermediary and other professionals help structure a compliant exchange; a broker should not promise tax deferral after the seller has already received unrestricted proceeds.

For a simplified qualifying exchange with only cash boot and no debt or other adjustments, recognized gain is generally limited to the lesser of realized gain or cash received. A $180,000 realized gain and $30,000 cash boot can leave $30,000 recognized and $150,000 deferred. Receiving boot does not necessarily make the entire gain immediately taxable.

The deferred amount is preserved through the replacement property's basis rather than forgiven. If replacement property is worth $670,000 and $150,000 of gain is deferred, its simplified basis is $520,000. Different debt, expense, related-party, and property facts can change the calculation. Separate recognition from tax rates, withholding, and the cash available to spend.

The exchange clocks start together

Fictional deferred exchange: relinquished property transfers January 16, 2026. Assume the tax-return due date including extensions is later than the 180th day, with no special relief.

  1. January 16
    Transfer starts both periods

    Do not wait for identification before starting the 180-day count.

  2. March 2 / Day 45
    Identification boundary

    Make the required signed written identification and timely delivery to an eligible recipient.

  3. July 15 / Day 180
    Receipt boundary

    Receive qualifying identified replacement property by this date under the stated return-date assumption.

The ordinary outside period is not 45 plus 180 days. An earlier tax-return due date, including extensions, can shorten the receipt period.

Calendar-day arithmetic; January 16 is day zero. All other exchange conditions, including restrictions on receiving sale proceeds, still apply. Chapter sources

Exchange worksheet / Cash-only boot

Fictional investment land: old adjusted basis $280,000; replacement land worth $390,000 plus $30,000 cash received. No debt, expenses, losses or other property.

  1. Realized gain$140,000

    $390,000 land + $30,000 cash - $280,000 old basis.

  2. Recognized gain$30,000

    Lesser of the $140,000 realized gain and $30,000 cash boot under these assumptions.

  3. Deferred gain$110,000

    $140,000 realized less $30,000 recognized; it has not disappeared.

  4. Replacement basis$280,000

    $280,000 old basis - $30,000 cash + $30,000 recognized gain. Check: $390,000 value - $110,000 deferred gain.

Receiving some cash does not necessarily make all realized gain currently taxable. The basis preserves the deferred amount.

Original hypothetical, not an exchange recommendation. Debt relief, exchange costs and other property require additional rules. Chapter sources

Withholding is a prepayment

Federal FIRPTA and California withholding have separate rules; withholding normally prepays tax and can differ substantially from the final liability.

Federal FIRPTA rules generally require the buyer to withhold 15% of a foreign seller's amount realized, subject to exceptions and reductions. Qualifying buyer-residence transactions can have no withholding at $300,000 or less and a 10% rate above $300,000 through $1 million. Residence-use requirements and documentation matter. The seller's citizenship label alone does not resolve tax residency.

California has separate real estate withholding rules, commonly using a sale-price method labeled 3 1/3% or an authorized alternative calculation, unless an exemption applies. For the current FTB total-sales-price method, use its specified decimal multiplier 0.0333, not the exact fraction 1/30: a $200,000 taxable sale-price amount produces $6,660. Form 593 and current FTB instructions address ownership allocation, exemptions, and other transaction conditions. State withholding is not limited to sellers who are foreign persons under FIRPTA.

Neither withholding figure is necessarily the seller's final income-tax bill. Treating withholding as an extra commission or a fixed tax on net profit misstates its function. The party responsible for withholding must follow the applicable documentation and remittance rules.

Apply the appropriate withholding system

Consider a foreign seller transferring a property for $800,000 to an individual buyer who satisfies the IRS residence-use requirements. Under the stated FIRPTA residence category, the 10% rate produces $80,000 of withholding, absent another applicable exemption or certificate. If the same purchase is solely for investment and no exception applies, the general 15% rate would produce $120,000. The buyer's intended and qualifying use changes the analysis.

California withholding must still be evaluated independently. A federal exemption does not automatically establish a Form 593 exemption. Likewise, a California principal-residence exemption determination does not replace verification of federal foreign-person status. The same seller may require different documentation under the two systems.

Withholding can reduce the seller's closing cash but normally functions as a tax prepayment credited through the applicable filing process. The amount may exceed or fall short of final liability. A salesperson should identify the issue early enough for escrow and qualified tax advisers to obtain required certifications and instructions rather than discovering the cash impact only after the seller has committed the proceeds elsewhere.

Apply the residence category before the FIRPTA rate

A foreign individual sells a U.S. real-property interest. Assume no other exemption or withholding certificate. Is the buyer's residence use qualifying?

Qualifying use; $290,000
Amount realized is at or below $300,000.The buyer-residence exception can eliminate withholding.
Qualifying use; $900,000
Amount realized exceeds $300,000 but is not over $1 million.10% of $900,000 = $90,000 withheld.
Investment use; $290,000
The buyer-residence requirement is not satisfied.Price alone does not create the exception: general 15% = $43,500.
Fictional cases. Qualifying residence use requires definite plans for buyer or family occupancy for at least 50% of used days in each of the first two 12-month periods; vacant days are excluded. Chapter sources

Property tax after transfer

Separate the 1% levy from the 2% inflation limit; reassessment and Proposition 8 recovery can exceed that growth rate, while supplemental bills adjust changed value.

Proposition 13: three different numbers

NumberWhat it controlsWhat it does not mean
Base-year valueGenerally the 1975 assessment or fair market value at a later reassessable ownership change or new constructionThe owner's income-tax basis or current loan balance
Up to 2% annual inflation increaseGrowth of the factored base-year value, using the applicable California Consumer Price Index adjustmentA guaranteed 2% increase, a 2% tax rate, or an absolute cap on every tax bill
1% general levyBasic ad valorem property tax applied to taxable assessed valueA promise that the entire bill equals 1% of purchase price

Permitted voter-approved debt rates can be added to the general levy. A bill may also contain separately authorized direct assessments; those charges are not simply another percentage of market value. Property-tax assessment, the tax rate, and total charges are separate steps. BOE overview, county bill components.

Rate example. Assume taxable assessed value is $600,000 after any exemptions, the general levy is 1%, permitted bond debt adds 0.12%, and an authorized direct assessment is $500:

Bill componentCalculationAmount
General levy$600,000 x 0.01$6,000
Stated bond debt$600,000 x 0.0012$720
Stated direct assessmentFixed charge$500
Illustrative annual total$6,000 + $720 + $500$7,220

The extra $1,220 does not, by itself, prove a Proposition 13 violation. The additions must have lawful authority; this example stipulates them rather than asserting a statewide combined rate.

Market value and enrolled value need not match

Annual assessment / Value summary

Original fictional excerpt for ordinary real property. Assume no reassessable event, exemptions, disaster adjustment, or other special rule.

  1. Valuation dateJanuary 1

    The annual lien-date comparison does not use the November installment due date.

  2. Current market value$750,000

    This estimates current value. Appreciation alone does not reset the Proposition 13 baseline.

  3. Factored base-year value$430,000

    This follows the existing base-year history and permitted annual inflation adjustments.

  4. Enrolled assessed value$430,000

    The lesser applicable value is enrolled. None of these fields establishes the owner's income-tax basis.

A $750,000 market estimate does not automatically produce a $750,000 assessment for this continuing owner.

An educational value comparison, not a county form. Assessed value and the eventual tax bill are different quantities. Chapter sources

Compound the assessment, not the market price

Assume a $500,000 base-year value, no reassessable event, no decline-in-value reduction, and the following hypothetical annual California inflation adjustments:

AdjustmentCalculationFactored base-year value
First year: inflation is 1%$500,000 x 1.01$505,000
Next year: inflation is 4%, but the increase is capped at 2%$505,000 x 1.02$515,100

Use each year's factor on the preceding factored value, not on the original $500,000 every year. An inflation factor below 2% produces a smaller increase; deflation can produce a decrease. A 15% rise in sale prices does not itself authorize a 15% increase in the factored base-year value. Revenue and Taxation Code section 51.

Cap the factor, then compound the value
Starting base-year value
$500,000
First increase: 1% of $500,000
$5,000
Next increase: capped 2% of $505,000
$10,100
Factored base-year value$515,100

The second year uses $505,000, not the original $500,000. Hypothetical 4% inflation is capped at 2% for that adjustment.

Assume no reassessment, decline-in-value reduction, or other adjustment. This is assessed-value growth, not a property-tax rate calculation. Chapter sources

Reassessment changes the baseline

A reassessable ownership change ordinarily establishes current fair market value for the interest transferred. A gift or inheritance can qualify even with no sale price. Exclusions can prevent reassessment, and an ordinary partial transfer need not reset the untransferred interest. For example, transferring a reassessable 50% interest ordinarily revalues that half, not automatically the entire parcel. BOE ownership-change guidance.

New construction ordinarily adds a new base-year component for its added market value, while the unaffected existing portion retains its value history. Assume existing factored value is $400,000 and a completed addition contributes $100,000 of market value: the combined value is $500,000, before other adjustments. Do not reset the entire property to a hypothetical $900,000 market value merely because an addition was built. Construction cost is not necessarily value added; routine maintenance generally is not assessable new construction. BOE construction guidance.

Reassess the interest or construction that changed

Assume a $400,000 existing factored value, no exclusion, and no other adjustment. Which independent event occurs?

Reassessable transfer of the whole property
Fair market value at transfer is $900,000.The whole transferred interest receives a $900,000 new base-year value.
Ordinary reassessable transfer of a 50% interest
The whole property is worth $900,000; the other half does not change ownership.Retain $200,000 for the unchanged half; add $450,000 for the transferred half: $650,000.
Completed addition with no ownership change
The addition contributes $100,000 of market value, regardless of whether its construction cost differs.Retain $400,000 for the unaffected property; add $100,000: $500,000.
Independent simplified alternatives, not successive events. Routine maintenance generally is not new construction; statutory exclusions and special ownership rules require separate review. Chapter sources

Proposition 8: compare two values each January 1

For ordinary decline-in-value assessment, enroll the lesser of current January 1 market value and the factored base-year value. A temporary reduction does not replace the Proposition 13 base-year track. The assessor continues annual review while the property is in decline-in-value status. A market decline from $900,000 to $800,000 does not justify a reduction if the applicable factored value is only $600,000. BOE Proposition 8.

Assume no ownership change, new construction, or exemption adjustment; the hypothetical annual inflation factor is 2% throughout:

Lien dateFactored base-year ceilingMarket valueEnrolled value
Year 1$600,000$520,000$520,000
Year 2$612,000$580,000$580,000
Year 3$624,240$650,000$624,240

Year 2 rises $60,000 / $520,000 = 11.54%, not 2%, because a temporary market-value assessment is recovering. Year 3 stops at the continuing factored ceiling, not $650,000. The 2% limit still governs annual growth of that ceiling; it does not cap recovery from the prior reduced assessment. A pending informal review does not suspend the obligation to pay the existing bill. BOE recovery and review FAQ.

Temporary reductions do not reset the ceiling

Assume successive January 1 valuations, a 2% annual inflation factor, and no ownership change, construction, exemption change, or other adjustment.

  1. Year 1
    Temporary reduction

    Factored ceiling $600,000; market $520,000. Enroll the lower $520,000.

  2. Year 2
    Market recovers below the ceiling

    Ceiling $612,000; market $580,000. Enroll $580,000, an 11.54% increase from the prior reduced assessment.

  3. Year 3
    Restore the factored ceiling

    Ceiling $624,240; market $650,000. Enroll $624,240 rather than the higher market value.

The 2% cap governs growth of the factored ceiling. Recovery from a temporarily reduced assessment can be greater than 2%.

Compare both values at each lien date. The reduced Year 1 assessment does not become a new Proposition 13 base year. Chapter sources

Regular bills and supplemental assessments

California's regular property-tax fiscal year runs July 1 through June 30. The annual lien date is January 1. Secured-tax installments are due November 1 and February 1. They ordinarily become delinquent at 5 p.m. or the close of business, whichever is later, on December 10 and April 10, subject to calendar adjustments. Due, lien, and delinquency dates serve different purposes. BOE property tax calendar.

A reassessable ownership change or completed new construction can create a supplemental assessment for the value change, beginning the first day of the following month. It adjusts the annual bill rather than charging the full value twice. An event from January through May can affect two fiscal years and produce two supplemental bills; a June-through-December event ordinarily produces one. Closing prorations and an impound account do not guarantee these later bills are covered. BOE supplemental assessment guidance.

Partial-year example. A sale on October 15 increases assessed value by $200,000. Assume a combined ad valorem rate of 1.1%, no exemption changes, and no other adjustments. The period begins November 1; its statutory factor is 0.67: $200,000 x 0.011 x 0.67 = $1,474 in supplemental tax. Use the statutory factor rather than substituting exact 8/12. This calculation is separate from contractual closing prorations. Section 75.41.

Supplemental assessment / Calculation extract

Fictional October 15 sale. Assume assessed value rises from $400,000 to $600,000, a 1.1% applicable ad valorem rate, and no exemptions or other adjustments.

  1. Supplemental assessed value$600,000 - $400,000 = $200,000

    Tax the increase, not the whole $600,000 again. The existing annual bill remains separate.

  2. Annual tax on the increase$200,000 x 0.011 = $2,200

    Apply the stated ad valorem rate before the statutory partial-year factor.

  3. Effective date and factorNovember 1 / 0.67

    Start the month after the event. Section 75.41 specifies 0.67; do not replace it with exact 8/12.

  4. Supplemental tax$2,200 x 0.67 = $1,474

    This statutory calculation is not the buyer-seller debit and credit used to allocate expenses at closing.

A later supplemental bill need not be covered by closing prorations or the lender's impound account. Check its own payment instructions.

Original educational extract, not a county bill. An October event ordinarily creates one supplemental bill for the affected fiscal year. Chapter sources

Proposition 19 is a separate qualification test

Proposition 19 permits qualifying replacement-residence base-year-value transfers for specified homeowners, including those at least age 55 and eligible disabled or disaster-affected owners, subject to requirements. Its intergenerational exclusion is narrower than the former broad parent-child rules: qualifying family homes or farms, continued qualifying use, value limits, and timely claims matter. A child inheriting a rental house does not automatically inherit its low assessed value. Indexed limits should be checked with BOE rather than memorized as permanently fixed.

Transfer tax and prorations

Use the stated tax base and day-count convention, then assign debits and credits according to who already paid or collected the item.

The common county documentary transfer tax authorized by Revenue and Taxation Code section 11911 is $0.55 per $500, or fraction, of the applicable taxable value. Value of qualifying liens remaining on the property is excluded under that provision. City taxes and local rules can add costs. A new purchase loan is not automatically a remaining old lien for this calculation.

If the stated taxable amount is $620,000 and only that county rate applies, divide by $500 to obtain 1,240 units, then multiply by $0.55: $682. Round units upward when a fractional $500 unit exists, not to the nearest whole unit.

For prorations, identify who already paid or collected the item and who should bear it for each period. Suppose annual taxes are $7,200 and the problem specifies a 360-day year. The daily amount is $20. If the seller owes 40 days that remain unpaid and the buyer will pay them, debit the seller and credit the buyer $800. If the seller already prepaid the buyer's 40-day share, reverse those entries. Use actual-day or 30-day conventions only when the problem or instructions specify them.

Rent and taxes run in opposite directions

A seller receives the full $3,000 rent for a thirty-day month before a sale. The contract assigns the first ten days to the seller and the remaining twenty days to the buyer. The seller collected $2,000 belonging economically to the buyer's period, so debit the seller and credit the buyer $2,000. That entry reallocates income already received.

Now assume the seller prepaid $600 of a charge covering the same month and the contract uses the same allocation. The buyer owes twenty-thirtieths, or $400, so debit the buyer and credit the seller $400. The direction reverses because the seller advanced an expense for the buyer's period. Netting the two prorations produces a $1,600 credit to the buyer, but calculate each separately before combining them.

Do not invent who owns the closing day. A question may assign that day to either party or specify an exact count. Nor should an annual charge automatically use a 360-day year unless the stated convention permits it. First identify the amount, covered period, allocation, and payment status. The debit and credit then follow from who owes whom.

The closing day determines who receives each day's rent

Fictional $3,100 August rent, all collected by the seller. Agreement uses actual days, closes August 12 and gives the closing day to the buyer.

  1. August 1-11
    Seller period / 11 days

    $3,100 / 31 = $100 per day. Seller is entitled to $1,100.

  2. August 12-31
    Buyer period / 20 days

    Count both August 12 and August 31: buyer is entitled to $2,000.

  3. At closing
    Debit seller; credit buyer $2,000

    Seller already collected the buyer's share. The credit transfers that benefit through settlement.

11 + 20 = 31 days. Giving the closing day to the seller instead would shift one $100 day; a different contract changes the allocation.

Original contractual calculation, not a universal California closing-day convention. Expense reimbursement may run in the opposite direction. Chapter sources
Payment status determines the proration direction

Who has already paid or received the amount allocated to the other party?

Seller prepaid buyer expense
The seller advanced a charge allocated to the buyer's period.Debit buyer; credit seller.
Buyer will pay seller expense
The seller's allocated share is unpaid and will be paid by the buyer.Debit seller; credit buyer.
Seller collected buyer rent
The seller already received rent allocated to the buyer's period.Debit seller; credit buyer.
Use the stated day count and closing-day allocation. Income already collected and expenses already advanced can produce opposite entries for the same ownership period. Chapter sources

Exam review

Label each calculation before using a percentage or subtraction; correct arithmetic on debt, basis, proceeds, or taxable gain cannot repair a mistaken category.

  • Cash proceeds are not taxable gain; withholding is a prepayment, not final liability.
  • Income-tax basis, property-tax assessed value, and market value are different quantities.
  • Proposition 13 separates the 1% general levy from the maximum 2% annual inflation increase in factored base-year value.
  • Reassessment events and Proposition 8 recovery can produce assessed-value increases greater than 2%.
  • Exclusion is not deferral, and a property-tax exclusion is not an income-tax exclusion.
  • Write the calculation base, payment status, and stated day-count convention before calculating prorations.
Work the numbers

Cash boot without losing the entire deferral

Assume a fully qualifying investment-property exchange. Relinquished property has a $700,000 fair market value and $400,000 adjusted basis. The taxpayer receives replacement real property worth $650,000 plus $50,000 cash. There is no debt, exchange expense, depreciation-recapture complication, related-party issue, or other adjustment. The exercise isolates ordinary cash boot; eligibility and timing are stipulated, not inferred from these numbers.

Relinquished property value
$700,000
Adjusted basis
$400,000
Replacement property value
$650,000
Cash received
$50,000

Find realized gain

700000 - 400000$300,000.00

The exchange produces $300,000 of economic gain before applying the nonrecognition rule. Receiving real property rather than only cash does not prevent gain from being realized. The $650,000 replacement value plus $50,000 cash accounts for the $700,000 received in this simplified exchange.

Limit current recognition

min(300000, 50000)$50,000.00

With only the stated cash boot and no complicating adjustments, recognize the lesser of realized gain and cash received. The taxpayer does not recognize the whole $300,000 merely because some cash was received. Conversely, boot cannot create recognized gain greater than the total gain actually realized.

Identify deferred gain

300000 - 50000$250,000.00

The remaining $250,000 is deferred, not permanently excluded. This number is not a tax payment, a lender payoff, or additional spendable cash. The final tax on the recognized portion depends on applicable tax rules and the taxpayer's circumstances, none of which are supplied by this calculation.

Carry the deferral into basis

650000 - 250000$400,000.00

Subtract deferred gain from the replacement property's fair market value to obtain its simplified $400,000 basis. A later taxable sale can therefore reveal the preserved gain. Assigning a fresh $650,000 basis while also deferring $250,000 would improperly erase the very gain the exchange rules postponed.

Test an unchanged-value later sale

650000 - 400000$250,000.00

If the replacement property were later sold in a fully taxable sale for the same $650,000 value, with no intervening basis changes or selling expenses, the gain would be $250,000. That matches the amount previously deferred. Do not subtract the earlier $50,000 recognized gain again; it was already accounted for in establishing replacement basis.

Step 1 of 5

TakeawayRecognized gain is a current tax category, deferred gain is preserved for later treatment, and basis carries that preservation forward. These figures do not prove exchange eligibility; actual transactions require timely identification, receipt, and compliance with the other governing requirements.

Exam pitfalls

Any boot makes the whole exchange taxable.

Compare realized gain with the relevant boot under the applicable rules.

Cash can cause partial recognition rather than destroy every deferral.

Deferred means permanently excluded.

Track the replacement property's basis.

A lower basis preserves gain for later tax treatment.

Every annual assessed-value increase is limited to 2%.

Check reassessment events and whether a temporary Proposition 8 reduction is recovering.

The factored base-year ceiling continues separately; recovery toward it can exceed 2% of the prior reduced assessment.
