Does Washington's new income tax affect the state's no-income-tax advantage for retirees?

For most retirees, no. Washington's no-income-tax advantage for retirement income remains intact for households with annual income below $1 million. Social Security, pensions, IRA withdrawals, and 401(k) distributions for the large majority of Washington retirees are still not subject to state income tax. For higher-income households approaching or above the $1 million threshold, the new tax creates a planning consideration that did not exist before 2026. Washington continues to have no income tax on most retirement income below the threshold, which remains a genuine advantage over states like California and Oregon.

Washington-Specific

Washington Has a New Income Tax: What Retirees Need to Know Before 2028

Q: Does Washington's new income tax affect retirement income like Social Security, pensions, and IRA withdrawals?

Only if total household income exceeds $1 million. Washington's new 9.9% income tax applies to household adjusted gross income above a $1 million standard deduction. Social Security, pension income, and IRA and 401(k) withdrawals all count toward that AGI total, but only the amount above $1 million is taxed. Since the vast majority of Washington retirees have household income below $1 million, most retirees will owe nothing under the new law. Washington still has no income tax on retirement income below the $1 million threshold.

Q: What is the $1 million threshold for Washington's new income tax?

The $1 million standard deduction under ESSB 6346 applies per household, not per person. A married couple filing together shares a single $1 million deduction. This creates a marriage penalty: two unmarried individuals each earning $900,000 would pay no Washington income tax, because each falls below the $1 million per-person threshold. If those same two individuals marry, their combined $1.8 million income shares one $1 million deduction, making $800,000 subject to the 9.9% tax. The deduction adjusts for inflation beginning in 2030.

Q: What is the Roth conversion opportunity before Washington's 2028 income tax?

For Washington households with large traditional IRA or 401(k) balances whose total income could exceed $1 million, converting pre-tax retirement accounts to Roth accounts in 2026 or 2027 may reduce long-term tax exposure. Roth conversions increase taxable income in the year of conversion. In 2026 and 2027, Washington has no income tax, so those conversions are taxed only at the federal level. After January 1, 2028, the same conversion would also be subject to Washington's 9.9% rate on amounts above $1 million. A CPA with retirement tax expertise should evaluate whether a Roth conversion strategy makes sense for a specific household.

Q: How does Washington's capital gains tax differ from the new income tax?

Washington has had a 7% capital gains tax on long-term gains above approximately $270,000 since 2022. That tax is separate from the new 9.9% income tax created by ESSB 6346. Critically, the capital gains tax does not apply to transactions inside retirement accounts. IRA and 401(k) withdrawals, Roth conversions, and defined-benefit pension income are not subject to the capital gains tax. Under ESSB 6346, the income tax and capital gains tax are calculated separately to avoid double taxation on the same income, though the interaction between the two can be complex in high-income scenarios.

Q: Is Washington's new income tax certain to take effect in 2028?

The law is signed and officially in effect, but its implementation faces ongoing legal and political uncertainty. A constitutional challenge is pending in Washington courts, similar to the challenge that initially blocked the state's capital gains tax before it was upheld by the Washington Supreme Court in 2023. A ballot referendum effort could also put the tax before voters in November 2026. Washington residents should plan as if the tax takes effect on January 1, 2028, while monitoring legal and legislative developments. A CPA is the right resource for tax planning under this uncertainty.

By Michael Gurr, Licensed Insurance Advisor, WAOIC #1335287 · University Place, Washington · Published June 9, 2026

Washington signed a new 9.9% income tax into law on March 30, 2026, effective January 1, 2028. The tax applies only to household income above $1 million per year, which means most Washington retirees are not affected. For households whose retirement income could approach or exceed that threshold, a specific planning window in 2026 and 2027 exists before the tax takes effect. Michael Gurr, a licensed insurance advisor in University Place, helps Pierce County and Western Washington households understand how this change fits into their retirement income picture. All tax planning routes to a CPA.

A woman from Gig Harbor called me last week. She had seen the news, "Washington passes income tax," and was worried. She and her husband were both retired. Social Security, a modest IRA, a paid-off home.

"Does this change everything for us?" she asked.

For her household: no. Their combined income was well below the threshold that triggers the new tax.

But her neighbor, a retired physician with $2.4 million in traditional IRA accounts and a pension, had a different answer to the same question. Not an emergency. But something worth talking through before the end of 2027.

Washington State signed a new income tax into law on March 30, 2026. For most Washington retirees, the honest answer is that this does not directly affect you. But understanding why, and knowing who it does affect, is worth 10 minutes.

What Washington Just Did, and When It Starts

Washington State has operated without a personal income tax for almost a century. That changed on March 30, 2026, when ESSB 6346 was signed into law.

The new tax applies a flat 9.9% rate to household adjusted gross income above $1 million. It does not take effect until January 1, 2028. First tax returns and payments are due in April 2029.

In 2026 and 2027, Washington still has no personal income tax. That matters for planning.

The law faces an ongoing constitutional challenge in Washington courts, similar to the legal fight over the state's capital gains tax that ultimately reached the Washington Supreme Court and was upheld in 2023. A ballot referendum effort could also put the law before voters in November 2026. Washington residents who may be affected should plan as if the tax takes effect in 2028 while monitoring what happens in the courts and the legislature.

Does This Affect Your Retirement Income?

The short answer for most readers: no.

The $1 million standard deduction under ESSB 6346 is per household, not per person. Total household income, including Social Security, pension distributions, IRA and 401(k) withdrawals, wages, investment income, and everything else that appears on the federal adjusted gross income line, must exceed $1 million before a single dollar of Washington income tax is owed.

The household whose combined retirement income is $85,000 per year owes nothing. The household at $220,000 owes nothing. The household at $750,000 owes nothing.

Only the portion above $1 million is taxed at 9.9%.

For context: the median household income in Pierce County is roughly $80,000 to $85,000. The overwhelming majority of retirees in Tacoma, University Place, Puyallup, and Gig Harbor are nowhere near the threshold.

What this means in plain English: if you and your spouse are retired and living on Social Security, a pension, and modest IRA withdrawals, Washington's new income tax does not apply to you. The advantage of living in a state with no income tax on most retirement income still applies.

Who Does Need to Pay Attention

Three situations where the new tax creates a planning conversation:

Situation 1

Large Traditional IRA or 401(k) Balances

A retiree or couple with $2 million or more in traditional (pre-tax) retirement accounts faces required minimum distributions beginning at age 73 or 75 depending on birth year. Those distributions count as ordinary income. Combined with Social Security, pension income, and any other sources, a household with large pre-tax accounts can approach or exceed the $1 million threshold in high-distribution years.

For these households, the 2026 to 2027 window, before the income tax takes effect, may be an opportunity to convert a portion of those accounts to Roth. Every dollar converted before January 1, 2028 is taxed at federal rates only. After that date, the same conversion would potentially trigger the 9.9% Washington rate on amounts above $1 million. A CPA with retirement tax expertise is the right guide for this conversation.

Situation 2

Washington Estate Tax Plus New Income Tax

Washington already has one of the most aggressive estate taxes in the country: an exemption of approximately $3 million per person in 2026, rates from 10 to 20 percent, and no portability between spouses. The new income tax adds a second layer.

For households with significant retirement account balances and real estate equity, which applies to more Western Washington homeowners than most people expect, the combined picture of income tax during life and the Washington estate tax at death has changed. An estate planning attorney and a CPA are the right professionals for this piece.

Situation 3

The Marriage Penalty

The $1 million deduction is per household, not per person. Two retired individuals each with $800,000 in income would pay no Washington income tax, because each is below the threshold individually. If those same two individuals are married, their combined $1.6 million income shares one $1 million deduction, and $600,000 would be subject to the 9.9% rate.

For high-income couples approaching retirement, this is a meaningful distinction that affects the retirement income coordination picture.

The Planning Window: Why 2026 and 2027 Matter

This is the most actionable section for households who are potentially affected.

Washington has no income tax in 2026. Washington has no income tax in 2027. The 9.9% rate takes effect January 1, 2028.

This creates a specific planning window.

Roth conversions, which move money from a traditional IRA into a Roth IRA, increase taxable income in the year of conversion. In 2026 or 2027, that conversion is taxed at federal rates only. After January 1, 2028, the same conversion could be subject to both federal income tax and Washington's 9.9% rate on the portion that pushes household income above $1 million.

For a Washington household with $3 million in a traditional IRA, converting a portion of those accounts before 2028 could meaningfully reduce the Washington tax owed on future required minimum distributions, permanently.

The math is specific to each household's income level, bracket, and account size. This is a CPA conversation. What Michael Gurr's office provides is the retirement income coordination picture: what the overall income structure looks like, what the Social Security and Medicare costs implications are, and who the right specialists are for the tax planning work.

What Washington's No-Income-Tax Advantage Still Means

For most Washington retirees, the headline from ESSB 6346 should not overshadow the still-real advantage of living here.

Washington does not tax Social Security income. Washington does not tax pension distributions. Washington does not tax IRA and 401(k) withdrawals. Washington does not tax wages from part-time work in retirement.

All of that remains true for households under the $1 million threshold, which is the vast majority of retirees in Pierce County and Western Washington.

The capital gains tax, a separate 7 percent tax on long-term gains above approximately $270,000, also does not apply to transactions inside retirement accounts. IRA withdrawals, Roth conversions, and pension income are not capital gains.

Washington remains one of the genuinely favorable states for retirement income planning below the high-income threshold. The new law creates a new planning conversation for some households. For most, it changes nothing.

The Honest Summary of What Changed

Before ESSB 6346	After ESSB 6346 (effective 2028)
No state income tax on any income	No state income tax below $1M household
No planning needed on income timing	Possible Roth conversion planning before 2028
Estate tax only concern for high-net-worth households	Income tax plus estate tax for high-net-worth households
Washington income tax advantage: clear	Washington income tax advantage: still real below $1M
Capital gains tax on gains above ~$270K	Same capital gains tax (retirement accounts still exempt)

Frequently Asked Questions

Does Washington State now have an income tax?

Yes, starting January 1, 2028. Washington State signed ESSB 6346 into law on March 30, 2026, creating Washington's first broad-based personal income tax. The tax applies at a flat 9.9% rate on household income above $1 million. For 2026 and 2027, Washington still has no personal income tax. The law faces an ongoing constitutional challenge.

Does Washington's new income tax affect retirement income like Social Security, pensions, and IRA withdrawals?

Only if total household income exceeds $1 million. Social Security, pension income, and IRA and 401(k) withdrawals all count toward household adjusted gross income under the new law, but only the amount above $1 million is taxed at 9.9%. The vast majority of Washington retirees have household income below $1 million and owe nothing under the new law.

What is the $1 million threshold and how does it apply to couples?

The $1 million standard deduction applies per household, not per person. A married couple shares one $1 million deduction regardless of how they file. Two unmarried individuals each earning $900,000 pay no Washington income tax. If those same two individuals are married, their $1.8 million combined income shares one deduction and $800,000 would be taxable at 9.9%.

What is the Roth conversion opportunity before Washington's 2028 tax?

For households with large traditional IRA accounts whose total income could exceed $1 million, converting pre-tax accounts to Roth in 2026 or 2027 may reduce long-term Washington tax exposure. Roth conversions before January 1, 2028 are taxed at federal rates only. After 2028, the same conversion could also trigger Washington's 9.9% rate on amounts above $1 million. A CPA with retirement tax expertise should evaluate whether this makes sense for a specific household.

How does Washington's capital gains tax differ from the new income tax?

They are separate taxes. Washington's 7% capital gains tax on long-term gains above approximately $270,000 has been in effect since 2022 and does not apply to retirement account transactions. The new 9.9% income tax under ESSB 6346 applies to total household AGI above $1 million. Both taxes are calculated separately to avoid double taxation on the same income.

Is Washington's new income tax certain to take effect in 2028?

The law is signed but faces both a constitutional challenge in Washington courts and a possible ballot referendum in November 2026. Washington residents who may be affected should plan as if the tax takes effect in 2028 while monitoring the legal and political developments. A CPA can help structure planning that accounts for both outcomes.

Does Washington's new income tax change the state's advantage for retirees?

For most retirees, no. Washington does not tax Social Security, pensions, IRA distributions, or 401(k) withdrawals for households below the $1 million threshold. That advantage remains intact for the large majority of Western Washington retirees. The new law creates a meaningful planning consideration only for higher-income households approaching or exceeding the threshold.
