Retirement Accounts for Government Workers — TSP, 457, and the Match
Public-sector retirement usually has more than one part: a pension, a savings plan you fund yourself, and — depending on where you work — Social Security. The pension gets the attention. The part you control gets underfunded.
Here's the good news, and it's genuinely unusual: the federal Thrift Savings Plan is among the cheapest retirement plans in the country. Where workers in other sectors have to hunt for a low-fee option, you're likely already in one.
Which means the mistake in this trade is rarely a bad product. It's not contributing enough to collect what your employer already offered you.
Your reality
The parts of this topic that hit your trade differently — and that generic advice skips.
The match is compensation you either take or forfeit
Many public employers contribute something automatically and match more when you contribute. Every payday you contribute below the match threshold, you leave part of your own pay behind — and it doesn't accumulate for later.
Low fees are an advantage most workers never get
The TSP's costs are a fraction of what many private and nonprofit plans charge. Over a career that difference is enormous, and it's already yours — no shopping, no switching, no salesperson required.
The pension is a floor, not the whole building
A pension typically replaces part of your pre-retirement income, based on your years of service and your highest earning years. The savings plan is what closes the distance between that and the life you actually want.
First moves
Three concrete steps, in order. Each one is a brick laid.
Look up your match formula and meet it this pay period
Find the exact contribution level that captures everything your employer will give, and set yours there. This is the single highest-return change available to you, and it takes one form.
Check what your plan is actually invested in
Contributing isn't the same as being invested well. Confirm whether you're in an age-appropriate lifecycle fund or sitting in the most conservative default, which can quietly cost decades of growth.
Ask your system what your pension will really replace
Request an estimate from your retirement system — most provide one. Knowing the share of your income it covers turns 'the pension will handle it' into a number you can plan against.
Frequently asked questions
Traditional or Roth in the TSP?
It turns on whether your tax rate is higher now or in retirement, which nobody knows for certain. Many public workers split the difference by using both. Worth noting: employer contributions go into the traditional side regardless of which you choose for your own.
I have a pension. Do I really need the TSP or 457 too?
Usually yes. Pensions are designed to replace part of your income, and in some state and local systems employees don't participate in Social Security at all — which makes the savings plan more important, not less. Get your projected pension figure before deciding.
What happens to my TSP or 457 if I leave government?
It stays yours. You can generally leave it in place or roll it elsewhere. The pension is the piece with a vesting requirement, so if you're considering leaving, that's the number to check first — the savings plan follows you either way.
