🇺🇸 US Real Estate Tax
1031 Exchange Calculator
See exactly how much federal + state tax you can defer by reinvesting your investment property sale proceeds via a 1031 like-kind exchange. Includes §1250 depreciation recapture and NIIT.
What is a 1031 exchange?
Section 1031 of the Internal Revenue Code allows you to defer capital gains tax on the sale of investment real estate by reinvesting the proceeds into another like-kind property. The key word is defer — you don't avoid the tax permanently, but you push it down the road, often indefinitely via repeated exchanges (and ultimately a step-up in basis at death).
The hard rules
- Real property only — TCJA (2017) removed personal property eligibility
- 45-day identification window from the day of sale
- 180-day completion window to close on the replacement
- Equal or greater value + debt — any cash kept (boot) is taxable
- Qualified intermediary required — you cannot constructively receive the sale proceeds
Disclaimer: Estimates only. 1031 exchanges are technical and time-sensitive. Engage a qualified intermediary and a tax professional before initiating. This is not financial or legal advice.
