Your TSP can pay you every month in retirement, just like a paycheck. TSP installments let you set the amount, pick how often you get paid, and change it any time. But two default settings catch a lot of federal retirees off guard: every withdrawal sells a slice of every fund you own, and shorter payment schedules get at least 20% withheld for taxes.
Here’s how it works, and how to set it up on purpose.
Three paychecks in retirement
Most federal retirees have three sources of income:
- Your FERS pension: a fixed monthly payment.
- Social Security: also a fixed monthly payment.
- Your TSP: the flexible one. It fills the gap between what your pension and Social Security pay and what you actually spend, and you control how much comes out and when.
That flexibility is the TSP’s biggest advantage, and the reason it’s worth setting up carefully.
Three ways to take money out
| Option | What it does | Good to know |
|---|---|---|
| Installments | A regular paycheck from your TSP | Flexible: change the amount or frequency any time |
| TSP annuity | Guaranteed monthly income for life | Permanent: once you buy it, you can’t undo it |
| Partial withdrawal | A one-time lump sum | $1,000 minimum; allowed while installments are running |
You can mix and match these. For example, many retirees run monthly installments and take an occasional partial withdrawal for a big expense like a new roof or a car.
How installments work
Installments are the closest thing to a TSP paycheck. You choose:
- How often: monthly, quarterly or annually.
- How much: either a fixed dollar amount you pick, or an amount based on your life expectancy that TSP recalculates each year.
- How long: payments continue until you stop them or your balance reaches zero.
Since September 2019, you can change the amount or frequency of your installments any time. If your spending changes, your TSP paycheck can change with it.
Default #1: every withdrawal sells every fund
TSP withdrawals come out pro rata, meaning proportionally from every fund you hold. You can’t tell TSP to pay you only from the G Fund. So if stocks are down, part of every withdrawal comes from selling your C, S or I Fund shares at a low price.
The workaround: take the withdrawal, then do an interfund transfer to rebalance your remaining money back to the mix you want. That way, you control what you’re holding after each payment, even though you can’t control what gets sold.
Traditional or Roth first?
If you have both traditional and Roth money in your TSP, you choose which one pays you first:
- Traditional first: taxable money comes out first, and your Roth keeps growing tax-free.
- Roth first: tax-free money comes out first, and your traditional balance stays invested longer.
When one balance runs out, your payments continue from the other. Which order makes sense depends on your tax bracket now and later, so it’s worth running the numbers before you choose.
Default #2: tax withholding
How much tax TSP holds back depends on how long your installments are scheduled to last:
| Installment schedule | Default federal withholding | Can you change it? |
|---|---|---|
| 10 years or more | Withheld as if you’re single, with no adjustments | Yes, with a W-4P |
| Less than 10 years | At least 20% | You can withhold more, but not less than 20% |
If you’re married or have other income and deductions, the default can leave you over- or under-withheld. Check your withholding when you set up installments, not at tax time.
Required minimum distributions and the TSP annuity
RMDs. Eventually, the IRS requires you to start taking money out of your traditional TSP:
- Born before 1960: RMDs start at 73.
- Born in 1960 or later: RMDs start at 75.
If your installments already pay out at least your RMD amount, you’re covered. If not, TSP will send you the difference.
The TSP annuity. An annuity turns part or all of your TSP into guaranteed monthly income for the rest of your life. That certainty is the appeal. The trade-off: once you buy it, the decision is permanent, and the money is no longer yours to change or leave to heirs beyond the annuity options you choose.
The bottom line
Your TSP can be a flexible monthly paycheck, but only if you set it up on purpose. Pick your amount and frequency, decide traditional or Roth first, and fix the two defaults: rebalance after withdrawals, and check your tax withholding.
