Real Estate Tax Calc
Depreciation as a built-in loss
Unlike stocks, real estate generates paper losses through depreciation without you selling anything. Cost segregation and bonus depreciation can amplify this, creating losses that offset passive income from other properties or, for short-term rentals with material participation, ordinary income.
Freeing suspended losses at sale
Passive losses you could not use are suspended and carry forward. When you sell a property in a fully taxable sale, its suspended losses are generally released and can offset other income — a planning lever for the year you take a big gain elsewhere.
Timing sales and the lazy 1031
Some investors deliberately place a new property in service (with cost segregation) in the same year they sell an appreciated asset, so the fresh depreciation loss offsets the gain — sometimes called a lazy 1031. It offsets rather than defers, and depreciation recapture still applies later, so run the numbers first.
A worked example: neutralizing a gain with cost-seg depreciation
Assume you realize a large gain in 2026 and want to soften the tax hit. You acquire a $1,500,000 short-term rental, place it in service, and commission an engineered cost segregation study that reclassifies $450,000 of the building into 5-, 7-, and 15-year property. The One Big Beautiful Bill Act restored 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025, so that entire $450,000 is deductible in year one rather than spread over decades.
If you and your spouse materially participate in the short-term rental — average guest stay of seven days or fewer, so it is not a rental activity under the passive-activity rules — the resulting loss is non-passive. A non-passive ordinary loss reduces your total taxable income, offsetting W-2 wages, business income, and interest, and to the extent it exceeds your other income it becomes a net operating loss that carries forward. The paper depreciation loss neutralizes income you would otherwise pay tax on, without your having sold anything at a loss.
Harvesting actual capital losses: the $3,000 rule and carryforwards
Separate from depreciation, you can harvest realized capital losses — for example by selling an underperforming property, a REIT position, or a real-estate fund at a loss. Capital losses first offset capital gains dollar-for-dollar. If your net capital losses exceed your gains, you may deduct up to $3,000 of the excess against ordinary income each year ($1,500 if married filing separately) under Section 1211.
Any remaining loss carries forward indefinitely under Section 1212 and keeps its short- or long-term character. There is no expiration for individuals — but carryforwards do not transfer at death. Unused capital-loss carryforwards die with the taxpayer, so an investor sitting on a large carryforward should plan to realize offsetting gains during their lifetime rather than let the benefit lapse.
The wash-sale rule does not apply to direct real estate
The wash-sale rule of Section 1091 disallows a loss when you sell a security and buy a substantially identical one within 30 days before or after the sale. That rule applies to stocks and securities — not to direct real property. You can sell a rental at a loss and purchase a similar rental the next day without any wash-sale disallowance.
Note the boundary: shares of a REIT or a real-estate ETF are securities, so selling and rebuying them within the 30-day window is subject to the wash-sale rule. Direct ownership of buildings and land is not, which gives real estate a flexibility that securities harvesting lacks.
Turning passive losses into usable deductions
Most rental losses are passive and can only offset passive income; the excess is suspended and carried forward under Section 469. There are three main ways to make real estate losses currently usable. First, the short-term rental approach — an average stay of seven days or fewer with material participation makes the activity non-passive. Second, qualifying as a real estate professional (more than 750 hours and more than half your personal-service time in real property trades or businesses, with material participation in your rentals) makes long-term rental losses non-passive. Third, the $25,000 active-participation allowance lets taxpayers with modified AGI under $100,000 deduct up to $25,000 of rental losses against other income, phasing out completely at $150,000.
If none of these apply, the losses are not wasted — they are suspended and released later. When you sell the property in a fully taxable transaction to an unrelated party, its suspended passive losses are freed and can offset any income, including the gain on the sale and income from other sources. Deliberately selling in a high-income year to unlock trapped losses is itself a harvesting strategy.
Recapture, NIIT, and the state-tax angle
Accelerated depreciation is not free money — it is a timing benefit. When you sell, the depreciation you claimed is recaptured. Depreciation on the 5- and 7-year personal property from a cost seg study is Section 1245 recapture taxed as ordinary income; depreciation on the building is unrecaptured Section 1250 gain taxed at up to 25%. A lazy 1031 offsets today and recaptures later, so model the eventual sale before assuming the strategy is a permanent win.
Two more layers matter. The 3.8% Net Investment Income Tax can apply to passive rental income and to gains on sale, though income that is non-passive because you materially participate as a real estate professional is generally excluded. And many states decouple from federal bonus depreciation — California, New York, and others do not allow 100% bonus, so your state loss may be far smaller than your federal loss. Always run the state numbers separately.
Common mistakes with real estate tax-loss harvesting
The most frequent errors: assuming an ordinary long-term rental loss can offset W-2 wages (it usually cannot without real estate professional status or the $25,000 allowance); forgetting that depreciation recapture will claw back the benefit at sale; using a rule-of-thumb cost seg estimate that will not survive an IRS audit instead of an engineered study; and overlooking that a related-party sale does not free suspended passive losses. Coordinate the timing of losses and gains within the same tax year, and confirm the character of each — ordinary versus capital — before assuming one offsets the other.
Coordinating with 1031 exchanges and Opportunity Zones
Tax-loss harvesting is one lever among several for managing gains. A 1031 exchange defers the entire gain (including recapture) by rolling proceeds into like-kind real estate, but it requires reinvesting in more real estate and following strict 45- and 180-day deadlines. A Qualified Opportunity Fund investment can defer an eligible capital gain and, after a 10-year hold, eliminate tax on the fund's own appreciation.
Harvesting differs: it does not require reinvestment and can offset ordinary income (via non-passive depreciation) or capital gains (via realized capital losses), but it does not make the tax on the harvested property disappear — recapture and the eventual sale still apply. Many investors combine tools: a 1031 to defer a sale gain, cost-seg losses to shelter current income, and capital-loss harvesting to mop up remaining gains. The right mix depends on your income, holding horizon, and estate plan.
Documentation and getting the character right
The single most common way tax-loss harvesting goes wrong is mismatching the character of losses and gains. Ordinary losses offset ordinary income efficiently; capital losses primarily offset capital gains and are capped at $3,000 against ordinary income. Before executing, map each expected gain and loss to its bucket — ordinary, short-term capital, long-term capital, Section 1231, unrecaptured Section 1250, and Section 1245 recapture — and confirm which offsets which.
Keep an engineered cost segregation report, a contemporaneous log of your material-participation hours if you rely on the short-term rental or real estate professional rules, brokerage statements for harvested securities, and basis schedules for every property. This documentation is what supports the losses if the IRS asks. Coordinate the timing with a CPA in the fourth quarter, before year-end, while you still have time to close a sale or place a property in service.
Think at the portfolio level, not property by property
Tax-loss harvesting works best when you think at the portfolio level rather than property by property. Passive income and losses from all your rental activities are netted together on Form 8582 before the result flows to your return, so a loss on one property can absorb income from another. A cost-seg-driven loss on a newly acquired short-term rental can shelter passive income thrown off by stabilized long-term rentals, and suspended losses from prior years are released as you generate passive income or sell. Review the whole portfolio each fall, project the year's net passive result, and decide whether to accelerate a purchase, place a property in service, or trigger a sale to optimize the combined outcome.
Frequently asked questions
Can real estate losses offset stock gains?
Suspended passive losses freed at the sale of a property can offset other income, including some gains, depending on your situation.
What is a lazy 1031?
Using a new property's cost-segregation depreciation loss to offset the gain from selling another property in the same year, instead of doing a formal 1031 exchange.
Does harvesting eliminate the tax?
It offsets or defers. Accelerated depreciation is recaptured at sale, so plan for that.
Does the wash-sale rule apply to rental property?
No. The wash-sale rule applies to stocks and securities, not to direct real estate. You can sell a rental at a loss and buy a similar one immediately. REIT shares and real-estate ETFs, however, are securities and are subject to the rule.
Do capital-loss carryforwards expire?
Not for individuals — they carry forward indefinitely. But unused carryforwards are lost at death and do not pass to heirs, so plan to use large carryforwards during your lifetime.
Can an ordinary rental loss offset my W-2 wages?
Generally only if the activity is non-passive — through the short-term rental rules with material participation, real estate professional status, or the $25,000 active-participation allowance for taxpayers under the income phase-out. Otherwise the loss is passive and is suspended until you have passive income or sell the property.
