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:
| Transfer | Recipient's basis in this example | Realized 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.
- Illustrative selling price
- $800,000
- Assumed selling expenses
- -$40,000
- Loan payoff
- -$300,000
Before other settlement debits, credits, or withholding.
- Gift: $400,000 donor basis; $350,000 gift-date value
At $375,000, the gain calculation is negative and the loss calculation is positive. The dual-basis rule yields neither gain nor loss, not a choice of the more favorable basis.
Values
| Series | Amount realized on later sale | Calculated gain or loss |
|---|---|---|
| Gift: $400,000 donor basis; $350,000 gift-date value | $300,000.00 | -$50,000.00 |
| Gift: $400,000 donor basis; $350,000 gift-date value | $350,000.00 | $0.00 |
| Gift: $400,000 donor basis; $350,000 gift-date value | $375,000.00 | $0.00 |
| Gift: $400,000 donor basis; $350,000 gift-date value | $400,000.00 | $0.00 |
| Gift: $400,000 donor basis; $350,000 gift-date value | $450,000.00 | $50,000.00 |
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.
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.
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.
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.
- January 16Transfer starts both periods
Do not wait for identification before starting the 180-day count.
- March 2 / Day 45Identification boundary
Make the required signed written identification and timely delivery to an eligible recipient.
- July 15 / Day 180Receipt 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.
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.
- Realized gain$140,000
$390,000 land + $30,000 cash - $280,000 old basis.
- Recognized gain$30,000
Lesser of the $140,000 realized gain and $30,000 cash boot under these assumptions.
- Deferred gain$110,000
$140,000 realized less $30,000 recognized; it has not disappeared.
- 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.
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.
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.
- Seller A / 40%
- $450,000 sale x 40% x 0.0333 = $5,994.
- Seller B / 60%
- $450,000 sale x 60% x 0.0333 = $8,991.
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
| Number | What it controls | What it does not mean |
|---|---|---|
| Base-year value | Generally the 1975 assessment or fair market value at a later reassessable ownership change or new construction | The owner's income-tax basis or current loan balance |
| Up to 2% annual inflation increase | Growth of the factored base-year value, using the applicable California Consumer Price Index adjustment | A guaranteed 2% increase, a 2% tax rate, or an absolute cap on every tax bill |
| 1% general levy | Basic ad valorem property tax applied to taxable assessed value | A 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 component | Calculation | Amount |
|---|---|---|
| General levy | $600,000 x 0.01 | $6,000 |
| Stated bond debt | $600,000 x 0.0012 | $720 |
| Stated direct assessment | Fixed 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.
Annual assessment / Value summary
Original fictional excerpt for ordinary real property. Assume no reassessable event, exemptions, disaster adjustment, or other special rule.
- Valuation dateJanuary 1
The annual lien-date comparison does not use the November installment due date.
- Current market value$750,000
This estimates current value. Appreciation alone does not reset the Proposition 13 baseline.
- Factored base-year value$430,000
This follows the existing base-year history and permitted annual inflation adjustments.
- 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.
- General levy
- 1% of $600,000 taxable assessed value
- Permitted bond debt
- Stipulated 0.12% of the same $600,000 base
- Direct assessment
- Stipulated lawful fixed charge, not another value percentage
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:
| Adjustment | Calculation | Factored 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.
- Starting base-year value
- $500,000
- First increase: 1% of $500,000
- $5,000
- Next increase: capped 2% of $505,000
- $10,100
The second year uses $505,000, not the original $500,000. Hypothetical 4% inflation is capped at 2% for that adjustment.
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.
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.
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 date | Factored base-year ceiling | Market value | Enrolled 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.
Assume successive January 1 valuations, a 2% annual inflation factor, and no ownership change, construction, exemption change, or other adjustment.
- Year 1Temporary reduction
Factored ceiling $600,000; market $520,000. Enroll the lower $520,000.
- Year 2Market recovers below the ceiling
Ceiling $612,000; market $580,000. Enroll $580,000, an 11.54% increase from the prior reduced assessment.
- Year 3Restore 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%.
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.
- Supplemental assessed value$600,000 - $400,000 = $200,000
Tax the increase, not the whole $600,000 again. The existing annual bill remains separate.
- Annual tax on the increase$200,000 x 0.011 = $2,200
Apply the stated ad valorem rate before the statutory partial-year factor.
- 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.
- 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.
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.
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.
- August 1-11Seller period / 11 days
$3,100 / 31 = $100 per day. Seller is entitled to $1,100.
- August 12-31Buyer period / 20 days
Count both August 12 and August 31: buyer is entitled to $2,000.
- At closingDebit 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.
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.
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.
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

Find realized gain
700000 - 400000The 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)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 - 50000The 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 - 250000Subtract 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 - 400000If 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.
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.
Chapter sourcesExam pitfalls
Any boot makes the whole exchange taxable.
Cash can cause partial recognition rather than destroy every deferral.
Deferred means permanently excluded.
A lower basis preserves gain for later tax treatment.
Every annual assessed-value increase is limited to 2%.
The factored base-year ceiling continues separately; recovery toward it can exceed 2% of the prior reduced assessment.
