1031 Exchange Rules in Colorado

Last reviewed: June 2026. State rules change. Verify current forms before closing.

What Is Different in Colorado

Colorado is one of the simplest withholding states for a 1031 exchange. Nonresident sellers face a modest 2% withholding at closing, the exemption is a one-page affirmation signed at the closing table, and there is no application to file in advance. Just as important is what Colorado does not do: despite what some websites claim, Colorado has no claw-back rule and no annual form tracking your deferred gain after you exchange into another state.

Does Colorado Conform to IRC Section 1031?

Yes. Colorado follows the federal like-kind exchange rules for real property. A 1031 exchange is an IRS-approved way to sell investment property and buy replacement property without paying tax on the gain right away. If your exchange qualifies for federal deferral, Colorado defers its income tax too. New to exchanges? Start with our 1031 exchange guide.

Colorado Tax Rate on Real Estate Gains

Colorado taxes capital gains as ordinary income at a flat 4.4% for 2026. On a $500,000 gain, that is about $22,000 of state tax on top of the federal bill. A qualifying exchange may defer all of it.

Nonresident Withholding at Closing

Under C.R.S. 39-22-604.5, the title or closing company must withhold on sales of Colorado real estate by nonresidents when the sales price exceeds $100,000. The amount is the lesser of 2% of the sales price or the seller's net proceeds. On an $800,000 sale, that is up to $16,000 held back at closing unless an exemption applies.

Because the withholding is capped at net proceeds, a heavily leveraged sale with little cash at closing produces little or no withholding.

How 1031 Exchangers Claim the Exemption: Form DR 1083

The exemption could hardly be easier. Form DR 1083 includes an affirmation that no Colorado income tax is reasonably estimated to be due from the sale. A transfer that is part of a qualifying 1031 exchange fits that affirmation, because the gain is deferred rather than recognized. The seller signs at closing; there is no advance application, no waiting period, and nothing to mail to the Department of Revenue ahead of time.

Tell your closing company early that the sale is part of an exchange, and make sure your qualified intermediary documentation is in place before the closing date. A qualified intermediary is the independent party that holds your sale proceeds during an exchange. WealthBuilder 1031 prepares exchange documentation that supports the DR 1083 affirmation.

If you take boot, meaning cash or other non-like-kind value, that portion of the gain is recognized, and the DR 1083 affirmation may no longer be accurate for the full sale. Talk to your tax advisor about partial exchanges before closing.

No Claw-Back: Correcting a Common Myth

Several QI and listing websites claim Colorado tracks deferred gain or claws it back when you sell out-of-state replacement property later. We reviewed the Colorado statutes and Department of Revenue guidance directly: no claw-back statute, regulation, or annual tracking form exists. There is no Colorado equivalent of California's FTB 3840 or Oregon's Schedule OR-24.

Once your exchange completes, Colorado has no ongoing filing requirement tied to the deferred gain. The gain simply carries forward in your basis under normal federal rules.

Federal Taxes Still Apply

A Colorado exchange defers two layers: federal and state. Here is what a taxable sale looks like without an exchange, using round numbers.

Example: $1,000,000 sale of a Colorado rental. Original purchase $600,000, with $100,000 of depreciation taken, so the adjusted basis is $500,000 and the total gain is $500,000.

Figures are illustrative and rounded. Your rates depend on income, filing status, and basis. Run your own numbers with our 1031 exchange calculators, then confirm them with your tax advisor.

Risks and Things That Go Wrong in Colorado Exchanges

• Late exchange setup. The DR 1083 affirmation works because the exchange defers the gain. If exchange documents are not signed before closing, the deferral fails and withholding applies.
• Boot surprises. Cash taken at closing, debt not offset with new debt or additional cash, or non-qualifying property received can create recognized gain and complicate the DR 1083 affirmation.
• Failed deadlines. The federal 45-day identification and 180-day completion rules apply with no state extensions. See the IRS rules for 1031 exchanges.
• Relying on bad information. Plenty of online charts get Colorado wrong, in both directions. Verify against the statute and current DR 1083, not a competitor's summary.
• Deferral is not elimination. The IRS and Colorado will tax the deferred gain when you eventually cash out. Plan the exit, not just the exchange.

Colorado 1031 Exchange FAQs

Does Colorado withhold on my sale if I do a 1031 exchange?
Generally no. The DR 1083 affirmation that no Colorado tax is reasonably estimated to be due covers a fully deferred exchange, and it is signed right at closing.

Who actually withholds the 2%?
The title insurance company or other closing agent. They remit it to the Colorado Department of Revenue if no exemption applies.

Does Colorado claw back deferred gain if I buy replacement property in another state?
No. We found no Colorado claw-back statute, regulation, or tracking form. Claims to the contrary on some websites are unsupported by primary sources.

Does the withholding apply to Colorado residents?
The statute targets nonresident sellers. Residents generally close without this withholding, though the income tax rules apply to everyone.

Is the withholding an extra tax?
No. It is a prepayment of Colorado income tax, credited when you file your Colorado return.
