Your TSP in Retirement: How Withdrawals Work

Updated June 2026 · Educational only — not financial, tax, or legal advice

Your FERS pension and Social Security are defined for you — but your Thrift Savings Plan is the one leg of the retirement stool where you decide how much to take and when. That flexibility is powerful, and it's also where retirees make the most expensive avoidable mistakes. Here's how TSP withdrawals actually work once you've separated.

The third leg of the stool

FERS retirement rests on three income streams: your pension, Social Security (bridged before 62 by the FERS supplement), and your TSP. The first two arrive automatically. Your TSP is the part you actively manage — and for many feds it's the largest single asset they own.

Your withdrawal options

Since the TSP Modernization Act, your options are far more flexible than they used to be. You can use any one — or a combination — of these:

• Installment payments. Regular automatic payments (monthly, quarterly, or annually), either a fixed dollar amount you choose or an amount based on IRS life-expectancy tables. You can start, stop, or change the amount whenever you like.
• Partial (single) withdrawals. Take a lump sum whenever you need one, and do it more than once. Useful for one-off expenses without committing to a payment stream.
• Full withdrawal. Take the entire balance at once (a large taxable event for traditional balances — usually not the tax-smart move).
• A TSP life annuity. Convert some or all of your balance into a guaranteed lifetime income stream through the TSP's annuity provider. Permanent and irreversible, so weigh it carefully.

When you withdraw, you can also choose whether the money comes from your traditional balance, your Roth balance, or proportionally from both — which matters for your taxes. See Roth vs. Traditional TSP.

When can you take it without a penalty?

Withdrawals before age 59½ generally carry a 10% early-withdrawal penalty on top of regular income tax — but there's a major exception for federal employees who separate at the right age. If you separate from service in or after the year you turn 55 (age 50, or 25 years of service, for special-category employees), your TSP withdrawals are penalty-free. This is one of the most important early-retirement levers, and we cover it in full in the TSP age-55 rule.

Required minimum distributions (RMDs)

You can't leave your traditional TSP untouched forever. Required minimum distributions generally begin at age 73 (rising to 75 later this decade), forcing a minimum taxable withdrawal each year. Two things to know: your Roth TSP is no longer subject to RMDs during your lifetime, and the years between retirement and your RMD age are often the best window for tax planning — see the conversion discussion in Roth vs. Traditional TSP.

The big decision the TSP won't make for you

The TSP gives you the mechanics; it doesn't tell you the sequence — how much to draw, from which balance, in which years, to keep your lifetime tax bill low and your money lasting. That sequencing, coordinated with your pension, supplement, Social Security timing, and RMDs, is the heart of a real retirement-income plan. You can also decide whether to keep your money in the TSP at all — see leave it in the TSP or roll to an IRA?
