If You Lose Money on a House, Is It Tax Deductible?

Whether losing money on a house sale is tax deductible comes down to how you used the property. A loss on a home you lived in as your personal residence cannot be deducted on your federal return. A loss on a rental, an investment property, or the business-use portion of a home generally can be deducted, subject to specific limits and reporting rules.¹

Why a Personal Residence Loss Gets No Deduction

Federal tax law allows individual loss deductions in three situations only: losses from a trade or business, losses from a transaction entered into for profit, and certain casualty or theft losses.² A house you bought to live in fits none of those categories. The IRS treats a decline in your home’s value the same way it treats depreciation on your car or a drop in the resale value of your furniture — a personal expense, not a deductible loss.

The size of the loss doesn’t change the answer. Selling your home for $15,000 less than you paid produces the same tax result as selling it for $150,000 less: zero deduction.

Claiming the loss anyway can trigger the accuracy-related penalty, which equals 20 percent of the tax underpayment caused by the improper deduction.³ The IRS applies it when a taxpayer claims deductions or credits they don’t qualify for.⁴

Home Office and Business-Use Portions

If you used a dedicated portion of your home exclusively and regularly for business, that portion is treated as business-use property. The IRS allows deductions tied to the business percentage, calculated by dividing the square footage used for business by the total home size.⁵

When you sell the whole home at a loss, the business-use share may qualify as a deductible business loss while the personal-use share stays non-deductible. If your home office occupied 15 percent of the home and you sold at a $40,000 loss, up to $6,000 of that loss could be deductible. You need to have actually claimed the home office deduction while living there; you can’t assign business use retroactively at the point of sale.

Rental and Investment Property

Property held to produce rental income or as a business investment falls into the “transaction entered into for profit” category, so a loss on its sale is deductible. The loss is classified as a capital loss and first offsets any capital gains you had during the same tax year.⁶

When capital losses exceed capital gains for the year, up to $3,000 of the excess ($1,500 if married filing separately) can reduce your ordinary income.⁷ Anything left carries forward to future years until the full loss is absorbed.⁸

An example. An investor sells a rental condo at a $20,000 loss with no capital gains that year. She deducts $3,000 against ordinary income now and carries forward $17,000. Next year, if no gains appear, another $3,000 comes off. The carryover continues until the full $20,000 is used, roughly seven years in this case.

The IRS expects you to show the property was genuinely held for profit. A vacation home used personally most of the year and rented only sporadically may be reclassified as personal use, killing the deduction. Rental listings, advertising records, and financial records showing profit motive all support the classification.

Converting Your Home to a Rental Before Selling

Some homeowners facing a loss consider converting the property to a rental first, hoping to salvage a deduction. It can work, but only for the portion of the drop that occurred after the conversion.

Your basis for calculating a loss starts at the lesser of your adjusted cost basis or the property’s fair market value on the date of conversion.⁹ You add improvements made after conversion and subtract depreciation claimed while renting.¹⁰

Take a house bought for $300,000 that had already fallen to $250,000 in fair market value when the owner moved out and started renting it. The starting basis for loss purposes is $250,000, the lower figure. After $15,000 of depreciation over three years, the adjusted basis becomes $235,000. Selling for $220,000 gives a deductible loss of $15,000, not the $80,000 gap between original purchase and sale price. The $50,000 that vanished while the property was still a personal residence disappears for tax purposes.

A professional appraisal on the conversion date is worth the few hundred dollars it costs. Without documented fair market value at conversion, defending your basis in an audit is hard.

Inherited Homes Sold at a Loss

Inherited property generally takes a basis equal to the fair market value on the date the prior owner died, not what they originally paid.¹¹ That stepped-up basis is the benchmark for any later gain or loss.

If the home was appraised at $350,000 on the date of death and you later sell it for $320,000, you have a $30,000 loss. Whether it’s deductible follows the same personal-versus-investment test. Move in and use it as your residence, and the loss is non-deductible.¹² Rent it out or hold it as an investment, and the loss is deductible as a capital loss under the same $3,000 annual limit and carryforward rules.⁷

If an estate tax return was filed and you received a Schedule A to Form 8971, your reported basis must match the estate tax value. Reporting a higher basis than the estate return used can trigger accuracy-related penalties.¹³

The Disaster Exception

There is one meaningful exception to the personal-residence rule. If your home is damaged or destroyed in a federally declared disaster, such as a hurricane, wildfire, or major flood, you may be able to deduct the casualty loss even though the property was personal use.² This is distinct from a market-driven loss. The damage has to come from a sudden, unexpected event in a disaster area that has received a formal federal or state declaration.

Two thresholds reduce the deductible amount. Each casualty event is reduced by $500. Total casualty losses for the year are further reduced by 10 percent of your adjusted gross income, though qualified disaster losses are exempt from that 10 percent floor.¹⁴ Any insurance reimbursement comes out first. If your policy covered the damage but you didn’t file a claim, the IRS won’t let you deduct what the insurer would have paid.

Casualty losses are reported on Form 4684, which requires the FEMA disaster declaration number (the “DR-” or “EM-” identifier). The deductible amount flows to Schedule A of Form 1040 rather than Schedule D.

Sales to Family Members Are Disallowed

Even a property that would otherwise qualify for loss treatment loses the deduction if you sell to a related party. The tax code disallows any loss on a sale between family members, including siblings, a spouse, parents, grandparents, children, and grandchildren.¹⁵

The rule reaches beyond blood relatives. Losses are also disallowed on sales to a corporation where you own more than 50 percent of the stock, a trust where you’re the grantor or a beneficiary, or an estate where you’re an executor selling to a beneficiary.¹⁵ Constructive ownership rules apply, so selling to an entity controlled by a family member counts too. A landlord unloading a money-losing rental cheaply to a sibling gets no deduction, regardless of how arm’s-length the negotiation felt.

Calculating Your Adjusted Basis

The deductible loss depends on your adjusted basis, meaning what you invested in the property from a tax perspective. Start with the purchase price and add certain closing costs from the original purchase:¹⁶

Abstract fees, owner’s title insurance, and title search costs
Attorney charges, recording fees, and deed preparation
Transfer taxes and surveys
Seller costs you agreed to pay, such as back taxes, commissions, or repairs the seller owed

After purchase, capital improvements increase your basis. A new roof, a kitchen remodel, or a finished basement all count. Routine maintenance and repairs don’t. Repainting a room or fixing a leaky faucet leaves basis unchanged.¹⁷

For rental property, depreciation you claimed (or were entitled to claim) reduces your basis. Buy a rental for $200,000, add $20,000 in improvements, claim $30,000 in depreciation, and your adjusted basis is $190,000. A sale at $180,000 produces a $10,000 deductible loss. The IRS reduces your basis by depreciation you were entitled to claim even if you never actually claimed it, which makes this a common error on investment property returns.

Reporting the Loss

Capital Losses on Investment Property

Each sale goes on Form 8949 with the property description, dates, proceeds, and adjusted basis. The net result feeds Schedule D of Form 1040, where the $3,000 annual limit and carryforward calculation happen.¹⁸ The net loss then transfers to the main Form 1040 to reduce taxable income.⁶

You’ll typically receive a Form 1099-S reporting gross proceeds after closing.¹⁹ The IRS gets a copy, so your reported proceeds have to match. If your adjusted basis reflects closing costs and improvements that aren’t visible on the 1099-S, keep documentation ready.

Casualty Losses From Disasters

Casualty losses go on Form 4684, not Form 8949. You need the FEMA declaration number, the fair market value before and after the event, your cost basis, and any insurance reimbursement. The deductible amount ultimately flows to Schedule A.¹⁴

Records to Keep

The IRS can generally assess additional tax within three years of your filing date.²⁰ If you’re carrying a loss forward, keep records for as long as the carryforward lasts plus three more years. A large investment property loss can produce carryforwards that stretch a decade.

At minimum, hold on to:

The original closing disclosure or settlement statement, which establishes purchase price and qualifying closing costs
Receipts for capital improvements, including contractor invoices, permits, and proof of payment
Year-by-year depreciation schedules from tax returns if the property was rented
A conversion appraisal, if you converted a personal home to rental use, documenting fair market value at the date of conversion
Form 1099-S from the sale closing
Prior-year Schedule D and Form 8949, especially if you’re carrying forward losses

Store copies digitally and physically. An appraisal or an organized file costs little compared to losing a deduction because you can’t substantiate the basis when an auditor asks.
