Updated July 25, 2026. Quick answer (2026): If you are weighing a move out of Washington in retirement, Washington already leaves retirement withdrawals untaxed, so moving saves you nothing on income tax. What a move actually escapes is a tax at death. Four taxes change when you move — income tax on withdrawals, state estate tax, state inheritance tax, and what probate costs your heirs. This page prices all four for Washington, then links a worked comparison for each destination.
What Washington actually charges a retiree
| Tax | Washington position, 2026 |
|---|---|
| State income tax | none on wages or retirement income (state levies a 7% excise on long-term capital gains above an inflation-adjusted deduction (~$270k+), plus a 2.9% surtax on gains over $1M enacted 2025 – retirement-account gains and distributions are exempt from it) |
| Social Security | Not taxed (no personal income tax). |
| Pension / 401(k) / IRA | Not taxed (no personal income tax; |
| Estate tax | yes – 2026 applicable exclusion per WA DOR tables: $3,076,000 for deaths 1/1/2026-6/30/2026, then $3,000,000 for deaths on/after 7/1/2026 (no further increases due to an expired CPI reference in statute). Rates for deaths on/after 7/1/2025: 10% to a top rate of 35% (35% on taxable amount over $9,000,000) – the highest state estate tax rate in the U.S. |
| Inheritance tax | none |
| Probate fee model | reasonable-fee |
| Probate filing fee | $200 statutory probate filing fee (RCW 36.18.020) plus county surcharges — typically ~$240 total (some counties $240-$290). Verified via app.leg.wa.gov and county schedules. |
| Small-estate limit | $100,000 — disposition of personal property by affidavit where the probate estate subject to probate ≤$100,000 (RCW 11.62.010); 40-day wait; personal property only. Verified. |
The mistake Washington retirees make
Washington taxes wages but exempts retirement-plan withdrawals. Every relocation calculator that compares top income-tax rates will therefore overstate your saving by roughly the whole amount — because on withdrawals you already pay nothing. The number that matters is at death.
Where Washington retirees go, and what each move is worth
Destinations below are drawn from documented retiree migration. Each links a worked, statute-cited comparison of all four taxes for that specific pair.
- Washington to Nevada — income-tax saving is zero; the money is at death
- Washington to Arizona — you would START paying state income tax
- Washington to Florida — income-tax saving is zero; the money is at death
- Washington to Idaho — you would START paying state income tax
More Washington corridors
Washington has no income tax at all, so the entire case for leaving rests on its estate tax — which has the highest top rate in the nation. These corridors price all four taxes that change on the move, each figure statute-cited for 2026:
Getting the sequence right
Leaving Washington cleanly is a sequencing problem as much as a tax one: domicile tests, what happens to property you keep behind, and the order of conversions and sales. See finding an advisor for a cross-state move for what to look for and the five questions to ask first.
Will Washington still tax me after I move away?
Not on your retirement withdrawals, once you genuinely change domicile — but that is a harder test than a change of address, and what you leave behind stays in reach.
- Domicile is a test, not an address. Washington can audit a departing resident. Days present, licence, registrations, where your advisers are and where you keep what you value all count.
- Property left behind stays reachable. Keeping a home in Washington can keep part of your estate inside Washington rules.
- Sequence any Roth conversion. It is taxed where you are domiciled in the year you convert — see how all 51 jurisdictions tax Roth conversions.

Getting the order right

Compare any two states yourself
The corridor pages cover the moves retirees make most often. For any other pair, the retirement tax comparison tool runs all 51 jurisdictions: pick two states and it returns the income-tax treatment of withdrawals, both death taxes and the probate fee model side by side. Enter an estate value and it tells you whether you cross either state’s estate-tax threshold — thresholds that run from Oregon’s $1,000,000 to Connecticut’s $15,000,000, several of them unindexed for years.
Which states should you even consider?
Published “best states to retire” lists blend an annual income-tax rate with a one-off estate threshold into a single score, which produces a ranking that is true for nobody. The personalised ranker takes your withdrawals and estate value and orders all 51 jurisdictions for your situation instead — Illinois ranks third for a $300,000 estate and drops off the list entirely at $6,000,000, because of a $4M cliff no listicle mentions.
