Real estate capital gains guide

Selling a home or rental property creates a unique blend of capital gains rules, exclusions, and recapture calculations. Careful record keeping can mean the difference between a six-figure exclusion and a surprise tax bill.

Step 1: Confirm ownership and use

To claim the primary residence exclusion you must satisfy the 2-out-of-5 test. Track the months you owned the property and the months you actually lived in it. Short absences (vacations, work travel) count as use. Longer rentals reduce the available exclusion.

Step 2: Build your adjusted basis

• Start with the original purchase price plus buyer-side closing costs.
• Add the cost of capital improvements: additions, new roofing, HVAC upgrades, landscaping projects that add value.
• Subtract any depreciation claimed while the property was rented or used for business purposes.

IRS references: Publication 523 and Publication 527.

Step 3: Estimate depreciation recapture

Depreciation reduces your basis and triggers “recapture” when you sell. The recaptured portion is taxed at a maximum 25% federal rate and cannot be sheltered by the primary residence exclusion. Include improvement schedules from your tax returns to prove the numbers.

Step 4: Evaluate partial exclusions

If you fail the 2-out-of-5 test because of a work relocation, health reasons, or other IRS-approved hardships, you may still claim a prorated exclusion. Multiply the full exclusion by the fraction of two years you satisfied the test. Publication 523 outlines qualifying scenarios.

State-level considerations

• California: Capital gain generally flows through the state income-tax system, while additional taxes and California-source rules can affect the result.
• New York: State brackets and possible New York City tax mean a single headline state rate is not a full calculation.
• Massachusetts: Income tax and a high-income surtax may apply; verify the current threshold and filing-year instructions.
• Washington: Washington uses a tiered capital gains excise tax for covered long-term gains and provides exclusions and deductions. Confirm the current deduction and asset rules with the Department of Revenue.
