Assumptions & Methodology
Federal long-term capital gains rates (0%, 15%, 20%) are based on 2026 brackets (Rev. Proc. 2025-32).
Depreciation recapture is taxed at 25% under IRC Section 1250.
The 3.8% Net Investment Income Tax (NIIT) applies when modified adjusted gross income exceeds $200,000 (single) or $250,000 (MFJ).
State tax rates are approximations based on top marginal rates. Actual rates may vary based on deductions, credits, and local taxes.
Depreciation estimates use straight-line depreciation with 27.5 years (residential) or 39 years (commercial), assuming 20% land allocation unless overridden.
Boot calculations assume that both cash boot and mortgage (debt) boot are taxable. Seller financing received is treated as cash boot.
This calculator does not account for installment sale treatment, AMT, depreciation bonus rules, or qualified opportunity zone deferrals.
Calculator Disclaimer
This calculator provides estimates for educational purposes only and does not constitute tax, legal, or financial advice. The calculations are based on simplified assumptions and may not reflect your actual tax situation.
Tax laws are complex and subject to change. State tax rates shown are approximations and may vary based on your specific circumstances, local taxes, and deductions.
A 1031 exchange has strict requirements including deadlines, like-kind property rules, and qualified intermediary requirements. Not all properties qualify. Consult with qualified tax and legal professionals before making any decisions.
