To report the sale of a vacation home on your tax return, you list the transaction on Form 8949, carry the totals to Schedule D, and add Form 4797 if you ever rented the property and claimed (or could have claimed) depreciation. Depending on the facts, you may also need Schedule E for rental activity in the year of sale, Form 6252 for an installment sale, and Form 8960 for the net investment income tax. Unlike a primary residence, a second home does not qualify for the Section 121 capital gains exclusion, so the full profit is taxable.1Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
The Core Forms: 8949 and Schedule D
Form 8949 is where the sale itself gets recorded: property description, purchase date, sale date, gross proceeds, and adjusted basis.2Internal Revenue Service. Instructions for Form 8949 (2025) Part I handles short-term transactions (held one year or less); Part II handles long-term. If the home had mixed personal and rental use, you may need to split the sale into two line entries, one for each portion.
The totals from Form 8949 flow onto Schedule D, which nets your gains and losses for the year and pushes the result to Form 1040.3Internal Revenue Service. About Form 8949, Sales and Other Dispositions of Capital Assets If the property was purely personal use with no rental history, these two forms are all you need for the sale itself.
Form 4797 for Any Rental History
If you ever rented the property, you almost certainly took depreciation, and the portion of gain attributable to that depreciation is taxed differently from the rest. It gets recaptured as unrecaptured Section 1250 gain at a maximum federal rate of 25%.4Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed – Section: Unrecaptured Section 1250 Gain Part III of Form 4797 is where you calculate that recapture.5Internal Revenue Service. Instructions for Form 4797 (2025)
For a vacation home held as an investment, the recapture calculated on Form 4797 is taxed at up to 25%, and any remaining gain above the recaptured depreciation goes on Form 8949 and Schedule D at long-term rates. If the rental activity rose to the level of a trade or business, the whole rental portion may be reported on Form 4797 instead of split between the two forms.6Internal Revenue Service. Sale or Trade of Business, Depreciation, Rentals
Here’s the trap. The recapture applies to depreciation “allowed or allowable,” meaning the IRS reduces your basis by the depreciation you should have claimed even if you never actually deducted it on a return.7Internal Revenue Service. Depreciation and Recapture 38Internal Revenue Service. Publication 946 (2025), How To Depreciate Property If you rented for years without depreciating, you lost the deduction and still owe the recapture. Skipping Form 4797 because you never deducted depreciation is exactly the kind of underreporting that draws an accuracy-related penalty.
Schedule E for the Year of Sale
If the property produced any rental income during the calendar year you sold it, that income and its expenses go on Schedule E through the date of sale, including a final partial-year depreciation deduction.9Internal Revenue Service. About Schedule E (Form 1040), Supplemental Income and Loss Schedule E results flow to Form 1040 separately from the capital gain reported on Schedule D. The two do not combine on a single line.
Form 6252 for Installment Sales
If the buyer is paying you over more than one tax year, you generally must report the gain on the installment method using Form 6252.10Internal Revenue Service. Publication 537 (2025), Installment Sales Each year you receive a payment, you recognize a proportional share of the total gain, which can keep you in a lower bracket than a lump-sum recognition would. You can elect out and report the full gain in the year of sale, but the installment method is unavailable for a loss.11Internal Revenue Service. About Form 6252, Installment Sale Income
Form 8960 for the Net Investment Income Tax
If your modified adjusted gross income exceeds $200,000 (single), $250,000 (married filing jointly), or $125,000 (married filing separately), you owe an additional 3.8% net investment income tax on the lesser of your net investment income or the amount by which your MAGI exceeds the threshold.12Internal Revenue Service. Topic No. 559, Net Investment Income Tax The gain from selling a vacation home is investment income for this purpose, reported on Line 5a of Form 8960.13Internal Revenue Service. Instructions for Form 8960 The thresholds are not indexed to inflation, so a large gain frequently pulls sellers who wouldn’t otherwise owe NIIT above the line.
Figuring the Gain You’ll Report
The number on Form 8949 is the sale price minus selling expenses (commissions, advertising, attorney fees, closing costs) minus your adjusted basis. Adjusted basis is the original purchase price plus closing costs at acquisition, plus capital improvements you made while you owned it, minus depreciation allowed or allowable during any rental period.
Capital improvements are additions that increase value or extend the property’s life: a new roof, a kitchen remodel, an added bathroom. Routine maintenance and repainting do not count.
Holding Period and Rate
Held one year or less, the gain is short-term and taxed at ordinary income rates. Held more than a year, it qualifies for long-term rates of 0%, 15%, or 20% depending on your taxable income and filing status.14Internal Revenue Service. Topic No. 409, Capital Gains and Losses For 2026, the 15% rate begins at $49,450 of taxable income for single filers and $98,900 for joint filers; the 20% rate applies above $545,500 (single) and $613,700 (joint).
Inherited or Gifted Property
If you inherited the home, your basis is generally the fair market value on the date the prior owner died, not what they paid for it.15Internal Revenue Service. Gifts and Inheritances The executor may have elected an alternate valuation date instead; Form 706 for the estate will show which was used.
A gifted home is different: you take the donor’s adjusted basis, not the current market value.16Internal Revenue Service. Basis of Property Received as a Gift If the fair market value at the time of the gift was lower than the donor’s basis, you use the donor’s basis for calculating a gain but the lower value for calculating a loss. A portion of any gift tax the donor paid may increase your basis.
Mixed Personal and Rental Use
Section 280A governs vacation homes used personally for part of the year and rented for the rest.17Office of the Law Revision Counsel. 26 USC 280A – Disallowance of Certain Expenses in Connection With Business Use of Home, Rental of Vacation Homes, Etc. For each year of ownership, expenses are split between rental days at fair market rent (deductible on Schedule E) and personal-use days. Days rented below market count as personal use.
If personal use exceeds the greater of 14 days or 10% of the fair-rental days, the home is treated as a personal residence for that year and rental deductions cannot exceed rental income. Unused depreciation carries forward and still reduces your basis at sale, which increases the reportable gain.
At the opposite extreme, if you rented the home for fewer than 15 days in a year, that year’s rental income is excluded from gross income entirely and no rental expenses are deducted. If every year of ownership fell under this 14-day limit, the home is treated as purely personal-use for tax purposes: no Form 4797, no Schedule E, and any loss on the sale is not deductible.
Capital Losses
A loss on a home used purely for personal enjoyment is not deductible. If the property had rental or investment use, the portion of the loss attributable to that use is deductible, offsetting capital gains first and then up to $3,000 of ordinary income per year, with anything left over carried forward.14Internal Revenue Service. Topic No. 409, Capital Gains and Losses
Estimated Tax in the Quarter of Sale
A large gain rarely fits inside your regular withholding. If you expect to owe $1,000 or more after withholding and credits, you generally need to make an estimated payment to avoid an underpayment penalty.18Internal Revenue Service. Large Gains, Lump Sum Distributions, Etc. Interest on underpayments runs at 7% annually as of early 2026.19Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026
You don’t have to spread the tax evenly across the year. Increase your estimated payment for the quarter the sale closed in, or use the annualized income method on Schedule AI of Form 2210 to match payments to when the income was actually received. If you have a W-2 job, another option is raising your federal withholding for the rest of the year to cover the gap.
Foreign Sellers
If you are a non-resident alien or foreign entity selling U.S. real property, the buyer generally must withhold 15% of the gross sale price under FIRPTA.20Internal Revenue Service. FIRPTA Withholding The withholding is a prepayment against your actual tax when you file a U.S. return, not an additional tax; any excess comes back as a refund. Reduced withholding is available in some cases by applying to the IRS before closing.
Penalties for Getting It Wrong
The IRS assesses a 20% accuracy-related penalty for substantial understatements or negligent disregard of the rules, rising to 40% for gross valuation misstatements.21Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments Missing depreciation recapture on a rented vacation home is a common trigger.
Filing on time but paying late costs 0.5% of the unpaid balance per month, up to 25%, dropping to 0.25% per month if you’re on an approved payment plan.22Internal Revenue Service. Failure to Pay Penalty Interest compounds on top. On a six-figure gain, those charges stack fast, which is why getting the estimated payment right in the quarter of sale saves as much money as the reporting itself.
