A 1031 exchange in Delaware lets you sell investment real estate and reinvest in like-kind property while deferring the tax on the gain. The federal rules apply the same way everywhere. Delaware adds a state tax on the gain and a nonresident withholding step at closing, while offering two things investors notice: no sales tax and among the lowest property taxes in the country. We act as your qualified intermediary, holding the proceeds and handling the documentation so the exchange holds from sale to closing.

How much is capital gains tax on real estate in Delaware?
Delaware taxes the gain as ordinary income, with a top rate of about 6.6%. That sits on top of the federal tax an exchange also defers:
- Long-term capital gains at 0%, 15%, or 20%, with the 20% rate applying above $545,500 of taxable income for single filers and $613,700 for married couples filing jointly in 2026.
- The 3.8% Net Investment Income Tax above $200,000 of modified adjusted gross income for single filers, $250,000 for married couples.
- Depreciation recapture, taxed as unrecaptured Section 1250 gain at up to 25%.
- Delaware's rate of up to about 6.6% on the gain.
Delaware conforms to Section 1031, so a properly structured exchange defers both the federal and the Delaware tax. The full federal framework is in our main 1031 exchange guide.
Delaware's nonresident withholding
When a nonresident sells Delaware real estate, the state collects an estimated tax payment at closing, computed on the gain, at 6.6% for an individual seller or 8.7% for a C-corporation, reported on Form 5403, the real estate tax return filed at recording. It is a prepayment against the Delaware tax, not an extra tax. In a 1031 exchange you note the like-kind exchange and the absence of recognized gain on Form 5403, supported by your intermediary's documentation, so the payment is not collected.
Delaware 1031 exchange rules and timeline
The federal deadlines govern, and they are strict:
- 45-day identification. Identify replacement property in writing within 45 days of the sale.
- 180-day closing. Close within 180 days of the sale, or by your return due date including extensions, whichever is earlier.
- No constructive receipt. Proceeds go to your qualified intermediary, never to you.
- Equal or greater value and debt. Reinvest all net proceeds and match or exceed the relinquished value and debt, or the shortfall is taxable boot.
- Same taxpayer. The entity that sold must be the entity that buys.
1031 exchanges across Delaware markets
Delaware is compact, and its exchange activity falls into two distinct markets. Wilmington and northern Delaware carry a commercial and multifamily market shaped by the state's role as a corporate and banking center, given how many companies are organized in Delaware. The southern coast is the other draw: Rehoboth Beach, Bethany Beach, and Lewes form a substantial second-home and vacation-rental market, popular with buyers from Maryland, Pennsylvania, Washington, and beyond, helped by the absence of sales tax. Newark adds university-driven demand and Dover anchors the central county. Delaware property tax is among the lowest in the country, which supports replacement-property yields, though you should confirm the rate for any specific deal.
Common Delaware 1031 exchange mistakes
- Not noting the exchange on Form 5403, so the estimated payment on the gain is collected and tied up.
- Taking receipt of the proceeds, even briefly, which disqualifies the exchange.
- Missing the 45-day identification window.
- Trading down or pulling cash out, which creates taxable boot.
