Roth IRA and State Taxes: What Every State Does Differently

Federal law treats qualified Roth IRA withdrawals as completely tax-free, but 41 states collect income taxes, and several of them have their own opinions about your retirement account. The difference between converting $100,000 in California versus Texas is a $13,300 state tax bill — and that gap only grows with larger balances.

The Federal Baseline in 2026

The Tax Cuts and Jobs Act extension passed in July 2025 permanently locked in the existing seven federal income tax brackets. The 2026 Roth IRA contribution limit sits at $7,000 for individuals under 50 and $8,000 for those 50 and older, with income phase-outs beginning at $150,000 for single filers and $236,000 for married filing jointly.

Qualified Roth distributions, meaning those taken after age 59½ from an account held at least five years, face zero federal income tax. Roth accounts also carry no required minimum distributions during the owner's lifetime, which makes them valuable for estate planning as well.

The Nine States Where None of This Is a State Tax Problem

Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming collect no broad-based individual income tax. Roth contributions, conversions, and withdrawals all pass through without any state tax consequence.

This is a material advantage for retirees doing large Roth conversions. A $200,000 conversion in Texas costs nothing in state tax. The same conversion in Minnesota triggers up to $15,900 in state income tax at Minnesota's top rate of 9.85%.

States With Income Taxes That Still Exempt Retirement Income

Several income-tax states carve out full or partial exemptions for retirement distributions, and some of those exemptions cover Roth IRA withdrawals specifically.

Illinois, Mississippi, and Pennsylvania exempt all retirement income, including Roth IRA distributions, from state income tax. Illinois taxes most ordinary income at a flat 4.95%, so this exemption is worth real money. Pennsylvania's flat rate is 3.07% as of late 2025, with no change enacted for 2026.

Other states offer partial exemptions. Georgia exempts up to $65,000 of retirement income per person for those 65 and older. Alabama excludes most retirement distributions entirely. Arkansas provides a $6,000 retirement income exclusion. The catch: these exemptions often apply to withdrawals but not to Roth conversion income, because a conversion is a taxable event in the year it occurs, not a distribution from the account.

That distinction matters. If you live in a state with a retirement income exemption and you convert a traditional IRA to a Roth, the converted amount typically counts as ordinary income in that tax year, not as a retirement distribution. Check your specific state's statute before assuming the exemption applies to conversions.

The High-Tax States Where Timing Is Everything

California, New York, New Jersey, and Oregon are the states most likely to cost you real money on a Roth conversion strategy.

California's top marginal rate is 13.3%, and the state conforms to federal Roth IRA rules, meaning contributions are made after-tax but qualified distributions are state-tax-free. The problem is the conversion. When you move money from a traditional IRA to a Roth, California taxes that income in full. A $300,000 conversion could add $39,900 in state tax for a high earner. California also imposes a 2.5% additional tax on early distributions, separate from the federal 10% penalty.

New York taxes conversions as ordinary income at rates up to 10.9% for the highest earners. However, New York does offer a $20,000 exclusion per year on retirement income for those 59½ and older, which can offset some of the withdrawal impact in later years.

New Jersey is unusual. It does not allow a deduction for traditional IRA contributions if those contributions were already deducted federally, which creates a tracking problem. Residents who contributed to a traditional IRA, took the federal deduction but got no New Jersey deduction, and then convert, may face partial double-taxation issues. New Jersey residents should verify their IRA basis records carefully.

Key Takeaways

• Nine states collect no income tax, making them the cleanest environments for Roth conversions of any size.
• Illinois, Mississippi, and Pennsylvania exempt Roth withdrawals from state tax, but conversion income is typically still taxable as ordinary income in the year of conversion.
• California's 13.3% top rate means a $300,000 Roth conversion can cost $39,900 in state tax alone, before any federal liability.
