How Does the Carryover Basis Rule Work in Divorce?

When you receive property in a divorce, the carryover basis rule means you take your former spouse’s original adjusted basis in that property rather than a fresh basis equal to its current value. Section 1041 of the Internal Revenue Code makes the transfer itself tax-free, but it also freezes the built-in gain in place and hands it to whoever ends up with the asset.¹ A home your spouse bought for $150,000 that’s worth $600,000 at the divorce still carries a $150,000 basis after the transfer, and you’ll owe capital gains tax on the appreciation when you sell.

How the Rule Works

Neither spouse recognizes gain or loss on a qualifying divorce transfer. The IRS treats it as a gift for tax purposes regardless of whether property was exchanged for cash, a release of marital rights, or the assumption of debt.² Because there’s no taxable event, there’s also no step-up. You inherit the transferor’s adjusted basis: original purchase price, plus capital improvements, minus any depreciation claimed. The holding period carries over too, so the clock on short-term versus long-term treatment doesn’t reset.¹

This is where settlement math gets misleading. Two assets can be worth the same on paper and carry very different tax bills. A brokerage account worth $400,000 with a $350,000 basis has $50,000 of built-in gain. A rental property worth $400,000 with a $100,000 basis has $300,000 of built-in gain. Taking the rental instead of the brokerage account looks even on the spreadsheet and isn’t.

What Counts as Incident to Divorce

Tax-free treatment applies only if the transfer is “incident to the divorce,” and there are two windows.

Any transfer made within one year after the marriage ends automatically qualifies. No link to a divorce instrument is required.²

Transfers made more than one year but within six years after the divorce qualify only if they’re made under a divorce or separation instrument, such as a court decree or written agreement.²

After six years, the transfer is presumed unrelated to the marriage. That presumption can be overcome only by showing legal or business impediments prevented an earlier transfer and that the property moved promptly after those impediments cleared.³ A transfer that falls outside these rules is treated as an ordinary sale or gift, which can trigger an immediate tax bill for the transferor.

The Marital Home

The carryover basis rule applies in full to the marital home. If your spouse bought it for $200,000 and transfers it to you in the divorce, your basis is $200,000 even if it’s now worth $700,000.

Section 121 lets a single filer exclude up to $250,000 of gain on the sale of a principal residence, provided you owned and used the home as your primary residence for at least two of the five years before the sale. Two divorce-specific rules make the tests easier to meet. Your former spouse’s period of ownership counts toward your two-year ownership requirement.⁴ And if your divorce agreement grants your former spouse the right to live in the home, you can count that time toward your own use requirement even after you’ve moved out.

The $250,000 exclusion helps but doesn’t cover everything. On a home that has appreciated by $400,000, $150,000 remains taxable to a single filer. Timing a sale carefully around the ownership and use tests can matter a lot.

Rental Property and Depreciation Recapture

Investment real estate carries an extra layer. You inherit not just the basis but the depreciation schedule, and you must keep claiming depreciation using the same method and remaining recovery period your former spouse was using.

At sale, gain attributable to previously claimed depreciation is subject to recapture as unrecaptured Section 1250 gain, taxed at a maximum federal rate of 25%.⁵ That’s a higher rate than the standard long-term capital gains brackets. The remaining gain above the recapture amount is taxed at regular capital gains rates.

The practical effect: a rental with $80,000 of accumulated depreciation carries $80,000 taxed at up to 25% on top of the capital gains tax on the rest of the appreciation. That cost doesn’t appear on a market appraisal, and it’s easy to miss during negotiation.

Stocks and Investment Accounts

For securities, the recipient inherits the transferor’s cost basis for each lot of shares, generally the original purchase price plus reinvested dividends and transaction costs. Each lot’s holding period carries over, which controls whether a future sale is short-term or long-term.¹

Long-term capital gains, on assets held more than a year, are taxed at 0%, 15%, or 20% depending on your taxable income.⁶ Short-term gains are taxed at ordinary rates, up to 37%.

Filing as single after the divorce also lowers the threshold for the 3.8% net investment income tax. It kicks in when modified adjusted gross income exceeds $200,000 for single filers or $125,000 for married filing separately.⁷ People who were nowhere near the $250,000 married-filing-jointly threshold can find themselves over the single threshold and owing the surtax on investment gains.

A brokerage account with dozens of lots is a record-keeping problem. If your former spouse bought the same stock on fifteen different dates, you need the basis for each purchase. Brokerages have tracked cost basis for shares bought after 2011, but older lots may require pulling historical statements.

Retirement Accounts Are Handled Differently

401(k)s, 403(b)s, and IRAs don’t follow the carryover basis framework. They move under their own rules, and using the wrong mechanism can trigger immediate taxation and a 10% early withdrawal penalty.

Employer Plans and QDROs

Splitting a 401(k) or other employer plan requires a Qualified Domestic Relations Order, a court order that directs the plan administrator to pay a portion of the participant’s benefits to a former spouse. The order must identify both parties and specify the amount or percentage.⁸

Under a QDRO, the former spouse reports the payments as if they were the plan participant and can roll all or part of the distribution into their own IRA tax-free. Without a QDRO, a withdrawal from the participant’s plan paid to the former spouse is treated as a taxable distribution to the participant, potentially with the early withdrawal penalty on top.⁸

IRAs

IRAs use a different mechanism. Transferring an IRA interest to a former spouse under a divorce or separation instrument is tax-free, and the transferred portion becomes the recipient’s own IRA going forward.⁹ If the transfer doesn’t meet these requirements, the IRS treats it as a taxable distribution to the original account holder, with a possible 10% penalty if that person is under 59½. A direct trustee-to-trustee transfer is the safest route.

When Section 1041 Doesn’t Apply

A few situations pull a transfer out of the tax-free rule entirely.

If the recipient spouse is a nonresident alien, Section 1041(d) says the non-recognition rule does not apply, and the transferor may recognize gain at the time of transfer.¹⁰ International divorces get caught by this often.

Transfers in trust also have a trap. When property is transferred into a trust for the benefit of a former spouse and the liabilities on the property exceed its adjusted basis, the excess is treated as taxable gain to the transferor.¹¹ A heavily mortgaged property with a low basis, placed in trust, can generate a tax bill no one bargained for.

Transfers to a third party on behalf of a former spouse are treated as two steps: a tax-free transfer to the former spouse, then an immediate transfer from that spouse to the third party. The second step can be taxable to the former spouse. For Section 1041 to apply to the first step, the transfer has to be required by the divorce instrument, or the former spouse must consent in writing that both parties intend Section 1041 to apply.²

Reporting the Sale

When you eventually sell a transferred asset, your gain is the sale price minus the carried-over adjusted basis. Not the value at the time of divorce. The original basis. That number is what the appreciation was measured against on day one, and it stays that way.

You report the sale on Form 8949, which feeds into Schedule D.¹² Using the wrong basis is one of the most common errors on these forms. Reporting the divorce-date value instead of the carried-over basis understates gain and invites IRS penalties when the discrepancy surfaces.

Get the Records Before the Divorce Closes

To calculate your basis when you sell, you need original purchase documents, records of capital improvements, depreciation schedules for any rental property, and cost-basis statements for investment accounts. The divorce decree documents the tax-free nature of the transfer itself.²

Collecting these records during the divorce, while communication is still going through attorneys, is far easier than reconstructing them years later. People who skip this step often can’t prove a lower basis when they sell and default to reporting zero basis, paying tax on the full sale price.
