Tax Issues When Dividing Assets in a Washington Divorce

Property transfers between spouses in a divorce are generally tax-free under IRC Section 1041. But "tax-free transfer" doesn't mean "no tax consequences." The receiving spouse inherits the original cost basis, meaning the tax bill is deferred — not eliminated. Ignore this, and you could accept a settlement that looks equal on paper but costs you tens of thousands more in taxes down the road.

The IRC 1041 Rule

Under Internal Revenue Code Section 1041, transfers of property between spouses (or former spouses if incident to divorce) are treated as gifts — no gain or loss is recognized. This applies to real estate, investment accounts, business interests, and personal property.

The catch: the receiving spouse takes the transferor's original cost basis. If your spouse bought stock for $20,000 and transfers it to you when it's worth $80,000, you inherit the $20,000 cost basis. When you sell, you'll owe capital gains tax on $60,000 in appreciation — even though you received it as part of your divorce settlement.

This is why comparing assets at face value during settlement negotiations is misleading. $80,000 in stock with a $20,000 basis is worth significantly less after tax than $80,000 in cash.

Real Estate Transfer Taxes (REET)

Washington's Real Estate Excise Tax (REET) applies to most property sales, but transfers between spouses incident to divorce are exempt. Under WAC 458-61A-203, you won't owe REET on a Quitclaim Deed executed as part of your dissolution decree.

To claim the exemption:

1. Complete a REET Affidavit
2. Reference WAC 458-61A-203 as the exemption code
3. Attach a certified copy of the signed dissolution decree
4. Submit to the County Treasurer when recording the deed

One caution: under WAC 458-61A-304, if the keeping spouse refinances within six months of the title transfer and the departing spouse is relieved of mortgage debt, the state may audit the transaction for potential retroactive REET on the assumed debt amount.

The Home Sale Exclusion

Under IRC Section 121, you can exclude up to $250,000 of capital gain ($500,000 for married couples filing jointly) when selling your primary residence, provided you've owned and lived in the home for at least two of the past five years.

Divorce creates two scenarios that threaten this exclusion:

Immediate sale during divorce. If you're still married and file jointly for the year of sale, you may still qualify for the $500,000 exclusion. Time the sale carefully relative to your final decree date.

Deferred sale after one spouse moves out. The spouse who moves out starts the clock on the "use test." If they're out of the house for more than three years before the eventual sale, they fail the two-out-of-five-year requirement. To protect the exclusion, include specific language in the decree allowing the resident spouse's occupancy to count toward the non-resident spouse's use test.

Retirement Account Transfers

Different retirement accounts have different tax treatment in divorce:

401(k) and 403(b) via QDRO: Tax-free transfer to the receiving spouse's account. The receiving spouse can roll it into an IRA with no tax consequences, or take a cash distribution — which triggers income tax but, uniquely, no 10% early withdrawal penalty for QDRO distributions regardless of age.

IRA transfer incident to divorce: Tax-free trustee-to-trustee transfer under IRC 408(d)(6). Early withdrawal penalties apply as normal if the receiving spouse takes cash out before age 59½.

The hidden trap: Traditional retirement accounts contain pre-tax dollars. A $100,000 401(k) is not worth $100,000 — it's worth roughly $75,000 after federal and state income tax on withdrawal (depending on your tax bracket). Always compare retirement assets to cash or real estate on an after-tax basis during settlement negotiations.

Spousal Maintenance Tax Treatment

For divorces finalized after December 31, 2018 (under the Tax Cuts and Jobs Act), spousal maintenance is:

• Non-deductible for the paying spouse
• Tax-free for the receiving spouse

This reversed the prior rule. Under the old system, a $3,000/month payment cost the payer roughly $2,100 after the tax deduction. Now it costs the full $3,000. Factor this into maintenance negotiations — the payer's effective cost is significantly higher than it was under pre-2019 divorces.

Filing Status Considerations

Your marital status on December 31 determines your tax filing status for the entire year. If your divorce is finalized on December 30, you file as single (or head of household) for the full year. If it's finalized on January 2, you file as married for the prior year.

This can make a meaningful difference in tax brackets, standard deduction amounts, and eligibility for credits. Discuss the timing of your final decree with your tax advisor if you're close to year-end.
