Tax Deductions for House Flippers: 2026 Write-Offs Guide

Last updated June 2026.

Flipping houses has a tax twist that catches almost every new flipper off guard: you usually do not deduct your renovation costs in the year you spend the money. The IRS treats a flip like inventory in a store, so most of what you pour into a project, the lumber, the labor, the new kitchen, gets added to the cost of the house and comes off your income only when the house sells. Get that timing wrong and your profit looks huge on paper in the buy year and tiny in the sell year. Get it right and you keep more of every deal.

This guide covers how a house flipper is taxed in 2026, which costs are capitalized versus deducted, why most active flippers are dealers who owe self-employment tax, and the write-offs you do get. It is general information, not tax advice for your specific return; the dealer-versus-investor line in particular turns on your facts, so confirm the details with your own accountant.

How are house flippers taxed?

An active house flipper is almost always a dealer, which means flip profits are ordinary income taxed at your regular rate (10% to 37% for 2026) plus 15.3% self-employment tax, not the lower long-term capital gains rates. The IRS sees a house you bought to fix and resell as inventory held for sale, like a product on a shelf, not an investment you hold for appreciation.

That single classification drives everything else. Because the property is inventory and not a capital asset, you cannot use the lower capital gains rates no matter how long the project takes, you cannot depreciate the house, you cannot defer the gain with a 1031 exchange, and you cannot use the home-sale exclusion under Section 121. Those breaks are for investors and homeowners. A flipper running a business does not get them. The trade-off is that, as a business, you do get to deduct your ordinary operating costs and you may qualify for the 20% qualified business income deduction, both covered below.

Am I a dealer or an investor?

You are a dealer if you hold property primarily for sale to customers in the ordinary course of business, and an investor if you hold for appreciation. If you shift toward buy-and-hold, our guide to tax deductions for real estate investors covers depreciation, cost segregation, and the passive loss rules that apply once a property becomes a rental. There is no bright-line test; the IRS and the courts weigh how often you buy and sell, how active you are in marketing the property, how much of your income comes from flipping, the scale of improvements, and your intent when you bought. Someone who flips several houses a year, advertises them, and treats it as a job is a dealer.

The distinction is the most valuable thing on this page because it changes your tax rate. A dealer reports flip profit as ordinary business income on Schedule C and owes self-employment tax. A true investor who flips one property held over a year may get long-term capital gains treatment and no self-employment tax. Most people who search for how to deduct flipping expenses are dealers, so this guide is written for the dealer case. If you genuinely flip one house as a side investment, talk to your accountant about whether investor treatment fits, because it is a different return.

Which flipping costs are capitalized and which are deducted?

Most direct project costs are capitalized into the house's basis and deducted when it sells, while a separate set of general business costs are deducted in the year you pay them. Capitalizing means the cost is not a current write-off; it is added to what the house cost you, and it reduces your gain at the closing table. This is the core accounting of a flip.

Costs that get capitalized into the project (deducted at sale) include:

• The purchase price of the house and the closing costs to acquire it (title, escrow, transfer taxes).
• Renovation materials. Lumber, paint, fixtures, flooring, cabinets, appliances, roofing, HVAC equipment installed in the house.
• Renovation labor. Payments to your general contractor and to subcontractors such as plumbers, electricians, and drywall crews.
• Permits and inspection fees tied to the rehab.
• Selling costs at the back end: the real estate commission, staging, and closing costs to sell, which reduce your amount realized.

The reason is simple: these costs create or improve the asset you are selling, so they belong in the asset's cost, not in a current expense line. You feel the deduction when the sale flows through your return, where your gain is the sale price minus your full capitalized basis minus selling costs.

How do holding costs like interest and property taxes work?

Interest on your acquisition or rehab loan and the property taxes during the renovation are generally capitalized into the project under the uniform capitalization rules, not deducted as you pay them. Carrying a flip is expensive: hard-money points, monthly interest, insurance, utilities, and county property taxes pile up while the house sits unsold. For a dealer, the default treatment for the interest and the property taxes tied to producing the property is to add them to basis.

This is one of the most misunderstood parts of flipping taxes, and it is worth a conversation with your CPA every project, because the capitalization rules have some flexibility on which carrying costs must be capitalized versus deducted, and the right answer depends on whether the property is being actively improved. The practical effect is the same as your other capitalized costs: you recover the interest and taxes against the sale proceeds when the house closes, not in real time.

What can I actually deduct in the current year?

The costs of running your flipping business, as opposed to the costs of a specific house, are deductible on Schedule C in the year you pay them. These are your overhead, and they are not tied to any one project's basis. The common ones:

• Vehicle and mileage. Driving to job sites, to suppliers, and to showings is deductible at the 2026 standard mileage rate of 72.5 cents per mile, up from 70 cents in 2025. Keep a log; commuting from home to a regular site can be nondeductible unless your home is your principal place of business.
• Tools and equipment. Your own power tools, ladders, and gear. Items under $2,500 can be expensed under the de minimis safe harbor; larger purchases can be expensed under Section 179 (up to $2,560,000 for 2026) or 100% bonus depreciation, which is permanent for property placed in service after January 19, 2025.
• Home office. If you run the business from a dedicated home space, the simplified method gives you $5 per square foot up to 300 square feet, a $1,500 cap.
• Software and subscriptions. Deal-analysis tools, accounting software, and a project-tracking app.
• Marketing. Finding deals: direct mail to homeowners, bandit-sign and online advertising, a website, and lead-list costs.
• Professional fees. Your accountant, bookkeeper, and business attorney.
• Phone and internet, the business-use share.
• Business insurance that covers the operation rather than a single property.

Keep these overhead costs cleanly separated from the per-house capitalized costs in your records, because they land in different places on the return and an auditor will expect to see the line drawn correctly.

What is the business code for house flipping?

There is no single official IRS code that says house flipper, and two codes are commonly used depending on how you describe the business. Flippers who buy, lightly fix, and resell often use 531390, Other Activities Related to Real Estate. Operators whose model is a full gut-and-rebuild sometimes use a construction code such as 236118, Residential Remodelers. You enter the code in box B of Schedule C.

The code is statistical; it does not change your deductions or your tax. What matters is the dealer-versus-investor reality of how you operate, not the six digits you pick. Choose the one that honestly describes your work and stay consistent year to year.

Does flipping houses qualify for the 20% QBI deduction?

Yes, in most cases. House flipping conducted as a trade or business is not a specified service trade or business, the category (health, law, accounting, consulting, and the like) that loses the qualified business income deduction at higher incomes. As a dealer reporting net profit on Schedule C, your flipping income is qualified business income, so you can generally take the 20% QBI deduction on it.

For 2026 the income thresholds where the wage and property limits start to apply are $201,750 of taxable income for single filers and $403,500 for joint filers; below those, the 20% comes off without complication. The deduction does not apply to a gain you report as a capital gain, which is one more reason the dealer-versus-investor question matters: dealer profit on Schedule C can feed the QBI deduction, an investor's capital gain cannot.

How much self-employment tax will I owe on a flip?

As a dealer you pay self-employment tax, 15.3% (12.4% Social Security plus 2.9% Medicare) on 92.35% of your net flipping profit. For 2026 the Social Security portion applies to the first $184,500 of combined earnings; Medicare has no cap. You deduct one-half of the self-employment tax above the line, which softens the income-tax side.

Flipping income comes with no withholding, and a single good flip can be a large profit, so estimated taxes matter more here than in most side businesses. You pay quarterly using Form 1040-ES, due roughly April 15, June 15, September 15, and January 15. The clean habit is to wire a chunk of every closing into a tax account the day the deal funds, because the self-employment tax on a $60,000 profit is real money the IRS expects in the same year.

Do I need to send 1099s to my contractors?

Yes. If you pay an unincorporated contractor or subcontractor $2,000 or more during 2026 for work on your flips, you issue them a Form 1099-NEC. That threshold rose from the old $600 under the 2025 law. Collect a Form W-9 from every crew before you pay them so you have the name, address, and taxpayer ID on hand at year end.

This catches a lot of flippers because the people you hire are exactly the workers who trigger 1099s: handymen, painters, landscapers, and trade subs paid by the job. Track what you pay each one across the year, because the threshold is per payee for the whole year, not per project. The payments are still capitalized into the house's basis; the 1099 is a separate reporting duty on top of that.

Can I deduct a loss if a flip loses money?

Yes. Because a dealer's flips are ordinary business inventory, a loss on a flip is an ordinary business loss, not a capital loss, so it offsets your other ordinary income without the $3,000 annual capital-loss limit that hits investors. A bad deal that sells for less than your basis plus selling costs produces a deductible ordinary loss on Schedule C.

That cuts both ways with dealer status. Dealers give up the capital gains rate on the wins but get unlimited ordinary-loss treatment on the losses, which can shelter income from your other flips or other work in a rough year. It is one of the few places where dealer classification works in your favor.

How do I keep flip records organized for taxes?

Because most of your costs sit in basis until the sale, the records have to survive across tax years and stay tied to the specific house. A flip that closes in a different year than it started means you are matching this year's renovation receipts to a sale that might be twelve or eighteen months out. Lose the receipts and you lose the basis, which means you pay tax on profit you did not actually make.

The reliable habit is to scan every material receipt, contractor invoice, permit, and closing statement the day it lands and tag it to the property, then export the project's costs to a spreadsheet so the capitalized basis is already totaled when the house sells. When a renovation invoice or a supplier estimate arrives as a PDF, a PDF to Excel converter turns it into spreadsheet rows you can drop straight into the project ledger.

A flip also runs on subs and suppliers. Before a crew sets foot on your job site, collecting and tracking each subcontractor's proof of coverage with certificate of insurance tracking software keeps an uninsured trade off your project and your liability. Ordering materials and fixtures against what actually shows up is cleaner when you track it with purchase order management software instead of guessing from a pile of delivery slips. And when the house closes, reconciling every draw, supplier payment, and the final settlement against your books in a bank statement to QuickBooks converter turns a year of project banking into clean entries your accountant can file from.

For the underlying recordkeeping rules, see our guides on whether the IRS accepts digital receipts, how long to keep business receipts, and how to categorize business expenses for taxes. If you hire trades on the rehab, the write-offs mirror those for construction contractors, and if you keep a flip as a hold instead of a sale, our rental property tax deductions guide covers the shift. When it is time to total a project, the receipt to Excel converter and receipt scanner for taxes turn a job box of material receipts and contractor invoices into a clean spreadsheet of your capitalized costs.
