TSP State Tax on Withdrawals: Which States Tax Your Distribution and Which Don't

The TSP Does Not Withhold State Taxes

When you take a distribution from your TSP, the recordkeeper withholds federal income taxes based on your elections — but the TSP does not withhold state income taxes. This means your state tax obligation is entirely your responsibility to calculate, report, and pay.

For retirees who move to a different state after separation, or who are considering where to establish residency in retirement, the state tax treatment of TSP distributions can have a significant impact on net retirement income.

States With No Income Tax

The simplest situation: if you reside in one of these states, your TSP distributions face zero state income tax:

• Alaska
• Florida
• Nevada
• New Hampshire (taxes interest and dividends only, not retirement distributions)
• South Dakota
• Tennessee
• Texas
• Washington
• Wyoming

If you retire in one of these states, your only tax obligation on TSP withdrawals is federal.

States That Exempt Federal Retirement Income

Several states exempt some or all federal pension income from state taxation. However, the treatment of TSP distributions often differs from the treatment of FERS or CSRS annuity payments, because the TSP is technically a defined contribution plan rather than a government pension.

Some states that exempt federal pension income still tax TSP withdrawals as regular retirement plan distributions. The specifics vary by state and can change with new tax legislation:

States that commonly exempt federal pension income (FERS/CSRS annuity): Alabama, Hawaii, Illinois, Kansas, Louisiana, Massachusetts, Michigan, Mississippi, New York, Pennsylvania, and several others provide partial or full exclusions for government pension income.

The critical distinction: An exclusion for "government pension income" or "federal retirement income" may or may not cover TSP distributions. In states like New York and Illinois, the exemption for government pensions generally extends to TSP distributions from a federal retirement plan. In other states, the exclusion applies only to the defined benefit pension (FERS/CSRS annuity), not to the TSP's defined contribution distributions.

How to Determine Your State's Treatment

Because state tax codes change regularly, verify your state's current rules through:

1. Your state's Department of Revenue website. Search for retirement income exclusions and look specifically for language about "defined contribution plans" or "Thrift Savings Plan."
2. A CPA or tax advisor in your state of residence. State tax rules for federal retirement income are a niche area — generic tax preparation software may not capture all available exclusions.
3. Your state's personal income tax instructions. Look for the retirement income subtraction or exclusion line on the state return.

The Residency Question

Your state tax obligation is based on your state of legal residency — not the state where you worked as a federal employee. Federal law (4 U.S.C. § 114) prohibits states from taxing the retirement income of former residents who have established domicile in another state.

If you worked in Virginia but retire to Florida, your TSP distributions are not subject to Virginia state income tax (assuming you properly establish Florida residency). This applies even if your federal agency was in Virginia and your service computation records reflect a Virginia duty station.

Some retirees strategically time large distributions (such as Roth conversions or total withdrawals) for years when they are resident in a no-income-tax state. This is legitimate tax planning, but make sure your change of domicile is genuine — simply renting a mailbox in Florida while living in Maryland does not change your tax residency.

Impact on Your Drawdown Strategy

State taxes can meaningfully change the math on your TSP withdrawal strategy. A $50,000 traditional TSP distribution in a state with a 5% income tax rate costs you an additional $2,500 beyond federal taxes. Over a 20-year retirement with regular distributions, the cumulative state tax bill can exceed $50,000.

For Roth TSP withdrawals, qualified distributions are tax-free at both the federal and state level in all states. This makes Roth TSP balance preservation and strategic Roth conversions even more valuable for retirees in high-tax states.

The TSP Withdrawal & Drawdown Strategy Guide covers tax withholding strategies for both federal and state obligations, including how to coordinate traditional and Roth distributions to manage your effective tax rate.
