Washington state does not tax pensions or any other retirement income. There is no state individual income tax at all, so pension checks, Social Security benefits, and withdrawals from 401(k)s, IRAs, and similar accounts arrive untouched by Olympia.1Washington Department of Revenue. Income Tax Federal income tax still applies to most of that money, and two other state taxes — a capital gains excise and an estate tax — can reach retirees in narrow situations.
What Washington Doesn’t Tax
Because Washington imposes no personal income tax, every category of retirement income is free of state tax:
- Private, government, and military pensions
- Social Security benefits, at any income level
- Distributions from 401(k), 403(b), and 457(b) plans
- Withdrawals from traditional and Roth IRAs
- Payments from qualified and non-qualified annuities
There is no state return to file and no state withholding form to submit. Washington funds itself largely through sales and excise taxes rather than income tax.
Federal Tax Still Applies
Living in a no-income-tax state does not change what the IRS collects. Pensions and 401(k) distributions funded with pre-tax dollars are taxed federally as ordinary income in the year you receive them. Traditional IRA withdrawals work the same way. Qualified Roth distributions come out federally tax-free, which pairs well with Washington’s lack of a state tax layer.
Social Security
Federal tax on Social Security depends on your combined income, defined as adjusted gross income plus tax-exempt interest plus half of your benefits.2Social Security Administration. Must I Pay Taxes on Social Security Benefits Once that figure exceeds $25,000 for a single filer or $32,000 for joint filers, part of your benefits becomes taxable. Above $34,000 single or $44,000 joint, up to 85% of benefits can be taxed.3Internal Revenue Service. IRS Reminds Taxpayers Their Social Security Benefits May Be Taxable Those thresholds are not indexed to inflation, so a Washington retiree drawing a pension, some IRA money, and Social Security can easily land in the range where 85% of the benefit is federally taxable.
Moving to Washington From a Taxing State
Federal law prevents any state from taxing the retirement income of a non-resident.4Office of the Law Revision Counsel. 4 USC 114 – Limitation on State Income Taxation of Certain Pension Income Once you establish residency in Washington, the state you left cannot reach back for your pension payments, qualified-plan distributions, IRA withdrawals, 403(b) or 457(b) income, or military retired pay. The protection covers substantially equal periodic payments made over your lifetime or over a period of at least ten years. Lump-sum distributions and some payouts from non-qualified plans fall outside the shield, so unusual arrangements are worth checking before you assume you’re clear.
Capital Gains Excise Tax
Washington imposes a 7% excise tax on long-term capital gains above an annual standard deduction.5Washington State Legislature. Washington Code 82.87.040 – Tax Imposed, Long-Term Capital Assets For 2025 the deduction is $278,000 per individual or married couple, and the 2026 figure, adjusted for inflation, had not been published at the time of writing.6Washington Department of Revenue. Capital Gains Tax
For most retirees, this tax does not apply. Assets held in 401(k) plans, IRAs, 403(b) accounts, and 457(b) deferred compensation plans are explicitly exempt, so trades inside those accounts never trigger it.7Washington State Legislature. RCW 82.87.050 – Exemptions Real estate is also fully exempt, so selling your home or a rental property creates no state capital gains liability.8Washington State Legislature. Chapter 82.87 RCW – Capital Gains Tax The tax bites only on long-term gains realized in a taxable brokerage account above the annual deduction. A retiree unloading a large concentrated stock position in one year could spread the sales across tax years to stay under the line.
Property Tax Relief for Senior Homeowners
Two state programs can lower housing costs in retirement.
Senior Exemption
You must be at least 61 by December 31 of the assessment year, and household income must fall below a threshold set by county.9Washington Department of Revenue. Property Tax Exemption for Seniors, People Retired Due to Disability and Veterans with Disabilities Limits vary widely. For the 2024–2026 tax years, the highest tier in King County reaches $84,000, while many smaller counties cap qualifying income near $41,000 or $42,000.10Washington State Department of Revenue. Income Thresholds for Senior Citizen and Disabled Persons Property Tax Exemption and Deferral For Tax Years 2024-2026 Surviving spouses as young as 57 can qualify if the deceased spouse was in the program.
Deferral
If you meet the age and income tests, you can defer property tax payments entirely. The deferred balance accrues 5% simple interest and comes due when you sell, die, or stop using the home as your primary residence.11Washington Department of Revenue. Property Tax Exemptions and Deferrals
Estate Tax on Retirement Assets
Washington’s estate tax is where retirement savings can face a serious state-level hit, but only after death. IRAs, 401(k) balances, and other retirement accounts are counted in the gross estate alongside real estate and other property.
For deaths in 2026, the filing threshold is $3,076,000.12Washington Department of Revenue. Estate Tax Tables Estates below that total owe nothing and file nothing. Above it, rates begin at 10% and climb through brackets of 15%, 17%, 19%, 23%, 26%, and 30% to a top rate of 35% on taxable estates over $9 million.13Washington State Legislature. RCW 83.100.040 – Estate Tax Imposed, Amount of Tax The state threshold sits far below the 2026 federal estate tax exemption of $15,000,000, so an estate that owes nothing to the IRS can still owe Washington a substantial amount.14Internal Revenue Service. Whats New – Estate and Gift Tax
The return and payment are due nine months after death. A six-month extension to file is available, but interest runs daily on any unpaid tax from the nine-month mark regardless of the extension.15Washington Department of Revenue. Estate Tax
Washington has no inheritance tax, so people who receive assets from a Washington resident owe nothing to the state on what they inherit.16Washington Department of Revenue. Estate Tax FAQ
If You Keep Working in Retirement
Wages are not retirement income, but retirees who take a part-time job in Washington should know about the WA Cares Fund. The program funds state long-term care benefits through a 0.58% premium on gross wages, deducted from the employee’s paycheck with no employer contribution and no cap tied to the Social Security wage base.17WA.gov. WA Cares for Employers The private-insurance opt-out window closed on December 31, 2022. Remaining exemptions are narrow: workers who live outside Washington, active-duty service members with civilian jobs, their spouses, veterans with a service-connected disability rating of 70% or higher, and holders of non-immigrant work visas.18WA Cares Fund. Exemptions Age and retirement status do not create an exemption, so a 70-year-old drawing a pension and working part-time at a Washington employer will still see the deduction on each paycheck.
