State tax guide
401(k) Rollover in Washington
Washington has no state income tax. Your rollover has zero state tax exposure regardless of how it's executed. You only need to worry about federal rules.
What Washington residents need to know
- Washington State has no personal income tax. A 401(k) rollover has no Washington state tax consequence.
- Note: Washington has a capital gains tax (7%) on long-term capital gains over $250,000 per year — but retirement account distributions are specifically excluded from this tax.
- No Washington state withholding will be taken from your distribution.
Watch out for
- Federal rules still apply — 20% withholding on indirect distributions, 60-day deadline, and 10% early-withdrawal penalty if under 59½.
- Washington's capital gains tax (enacted 2021) specifically exempts retirement account distributions. This exclusion is confirmed, but verify with a CPA if you are taking large distributions alongside large capital gains in the same year.
Good news
Despite the capital gains tax, retirement account distributions remain completely state-tax-free in Washington. The exclusion is explicit in the law.
The right move for Washington residents
The most important step is the same in every state: do a direct rollover — custodian-to-custodian, no check issued to you. This eliminates the 20% mandatory federal withholding, the 60-day deadline risk, and all state tax exposure in one step.
