Taxes for Government Workers — Pensions, TSP Choices, and Credits
Most of a public servant's tax picture is ordinary: wages, withholding, a W-2. The parts worth attention are the retirement pieces, because the choices you make now decide what you owe decades from now.
There's also a state-level wrinkle that catches people at exactly the wrong moment — states treat public pensions very differently, and where you retire can change what your pension is worth after tax.
None of this requires expertise. It requires asking two or three specific questions before the decisions are locked in.
Your reality
The parts of this topic that hit your trade differently — and that generic advice skips.
Traditional and Roth are a bet on your future rate
Traditional contributions lower your taxable income now and are taxed on the way out. Roth is the reverse. Nobody knows their future bracket, which is why plenty of public workers deliberately hold some of each.
States don't treat public pensions the same way
Some states exempt public pension income partly or entirely; others tax it like any other income. If you might retire somewhere other than where you worked, that difference belongs in the decision.
A credit for retirement contributions goes unclaimed
There's a federal credit aimed at lower and middle incomes for contributing to a retirement plan, including a TSP or 457. Plenty of public workers qualify and never claim it, because a self-prepared return doesn't ask.
First moves
Three concrete steps, in order. Each one is a brick laid.
Decide traditional versus Roth on purpose
Look at your bracket now and what you expect in retirement, then choose deliberately rather than leaving the default. Note that employer contributions typically land on the traditional side no matter what you pick for your own.
Ask specifically about the retirement savings credit
If you contributed to a TSP, 457 or IRA, name the retirement savings contributions credit to your preparer and ask whether you qualify. It's routinely missed when nobody raises it.
Check the pension tax rules where you plan to retire
Before committing to a retirement state, look up how it treats public pension income and whether it taxes Social Security. It's an easy question to answer years early and an expensive one to discover late.
Frequently asked questions
Is my pension taxable?
Federally, pension income is generally taxable, though the portion representing contributions you already paid tax on may not be. State treatment varies widely — some exempt public pensions, some don't. Your retirement system can tell you how your specific benefit is reported.
Does my TSP contribution lower my taxes now?
Traditional contributions reduce your taxable wages in the year you make them; Roth contributions don't, but qualified withdrawals come out tax-free later. Both may also count toward the retirement savings credit if your income qualifies.
I worked in one state and want to retire in another.
Generally the state you live in when you receive the income is the one that taxes it, not the state where you earned the pension. Because the rules and exceptions vary, confirm with a preparer before you move — this is worth getting right once rather than discovering annually.
