Cash uplift from 1031
$56,352(30% more reinvestable capital)
Realized gain of $185,250 on adjusted basis of $210,000. A qualifying 1031 keeps that tax invested in replacement real estate instead of paying it now. If you keep cash from the sale (cash boot) or take on less debt, that boot is taxable in the year of the exchange.
Overview
A 1031 exchange calculator estimates federal capital gains, depreciation recapture, NIIT, and state tax on the sale of an investment property, and shows the side-by-side difference between an outright sale and a like-kind exchange. The federal tax bill is generally deferred by a valid 1031, while state treatment varies.
A fully qualifying 1031 could defer roughly $56,352 of federal and state tax on this sale, keeping that capital invested in replacement real estate.
Combined federal, recapture, NIIT, and state tax is 30% of the realized gain. A qualifying 1031 can keep more capital invested in replacement real estate.
| Metric | Often strong | Watch out | Why it matters |
|---|---|---|---|
| Outright-sale tax bill | Below 20% of realized gain | Above 35% of realized gain | Combined federal, recapture, NIIT, and state tax can take 25-40% of the gain on a long-held rental. |
| Depreciation recapture tax | Manageable share of total tax | Largest single tax line | Recapture is taxed at up to 25% federal. On 10+ year holds it often exceeds the capital gains tax. |
| Estimated 1031 tax savings | High enough to justify QI fees + replacement-property work | Low, suggesting flexibility may matter more | The larger the tax bill, the more valuable it can be to keep that capital invested instead of paying tax now. |
| 1031 reinvestment cash | Equal to net sale proceeds | Reduced by any cash you keep (cash boot) | Any cash kept out of the exchange or debt not replaced becomes taxable boot in the year of sale. |
Add the expected sale price, selling costs (typically 6% to 8%), and the outstanding mortgage balance to be paid off at closing.
Enter the original purchase price, capital improvements that added to basis, and cumulative depreciation taken. Your tax preparer can pull cumulative depreciation from prior Schedule E and Form 4562 filings.
Pick a federal long-term capital gains rate (0%, 15%, or 20% based on 2026 brackets), keep recapture at 25% unless your ordinary rate is lower, set NIIT to 3.8% if your MAGI is above $200K single / $250K MFJ, and add your state rate.
The side-by-side panel shows federal capital gains, depreciation recapture, NIIT, and state tax separately for an outright sale, and how much of that bill a qualifying 1031 exchange may defer.
A calculator can estimate tax savings, but the exchange still needs written replacement-property identification within 45 days and closing within 180 days of the relinquished sale.
Next steps
This calculator is a planning estimate. A 1031 exchange still needs a qualified intermediary, replacement-property identification, and tax advice before the sale closes.
