Should I take my pension as a lump sum or monthly payments?

Which public plans offer a lump sum

Oregon PERS: the IAP

The Individual Account Program (IAP) is a savings account, separate from the pension. At retirement the PERS pre-retirement guide lists these choices:

• A one-time lump sum of the whole balance, paid to you, rolled over, or split between the two (the rollover part must be at least $500).
• Installments over 5, 10, 15 or 20 years, or over your anticipated life span, paid monthly, quarterly or yearly (each payment at least $200).

Only the lump sum and the 5-year installments can be rolled over. The longer installment choices cannot.

Oregon PERS: Tier One and Tier Two lump-sum options

Tier One and Tier Two members have two kinds of pension lump sum, according to the same guide:

• Partial lump sum (lump-sum Options 1, 2, 2A, 3 and 3A): you get a refund of your member account balance, plus a smaller monthly pension based only on employer contributions.
• Total (double) lump sum: you get your account balance plus a matching amount from your employer's account, and no monthly pension at all. You keep eligibility for PERS retiree health insurance.

Lump sums can be paid in up to five yearly installments, with the first paid within 92 days of retirement. These options come from the Tier One/Tier Two guide, so OPSRP pension members should check OPSRP's own rules; see Tier One, Tier Two and OPSRP for the differences.

Washington DRS: Plan 3 and Plan 2

Plan 3 has two parts: a pension your employer pays for, and an investment account you contribute to. The pension is paid monthly. For the investment account, DRS: PERS Plan 3 lists a lump sum, scheduled payments in an amount and frequency you choose, a rollover, leaving the money invested, or buying a lifetime annuity from DRS (the TAP annuity, minimum $25,000, with a 3% yearly COLA). DRS gives this example: a $10,000 lump sum arrives as an $8,000 check after 20% federal withholding.

Plan 2 pensions are paid monthly. DRS: PERS Plan 2 says you can withdraw your contributions only when you leave covered employment, and that Plan 2 members who withdraw or roll over their contributions forfeit their pension. That is a refund, not a retirement lump sum.

FERS

The FERS basic annuity is monthly. If you leave federal service before you can retire, you can ask for a refund of your retirement contributions, but the refunded service then does not count toward an annuity amount, and taking the refund ends any right to a deferred annuity (OPM: Former employees). A retiree with a life-threatening affliction or other critical medical condition may be able to choose an "alternative form of annuity": a lump sum of contributions plus a permanently reduced annuity (OPM: Alternative annuity election information). Your Thrift Savings Plan is separate and has its own withdrawal choices.

Monthly vs lump sum: the trade-offs

Longevity risk

Longevity risk is the chance you live longer than your money lasts. A monthly pension removes that risk: it keeps paying at 95 the same as at 65. A lump sum has to be stretched over a lifetime nobody can predict. If you spend it too fast, or the market drops early in retirement, the money may run short in your 80s, when it is hardest to go back to work.

Inflation

Prices roughly double over 25 years at 3% inflation. Many public pensions include a cost-of-living adjustment (COLA), though it is often capped. Oregon PERS COLAs are up to 2% a year (with a blended rate for Tier One service after October 1, 2013), and Washington Plan 2 and Plan 3 COLAs are capped at 3% (Oregon PERS: Benefit component comparisons, DRS: COLA). A lump sum has no built-in COLA. You would need to invest it so that it grows.

When a lump sum may appeal

• You have serious health problems and a shorter expected life span.
• You have other guaranteed income (another pension, Social Security) that covers basic bills.
• You need to pay off high-interest debt, or want to leave money to heirs.
• The account is invested, like the IAP or Plan 3, and is not a lifetime pension to begin with.

A lump sum also invites mistakes: spending too quickly, investing too aggressively, or paying a large tax bill by taking it all in one year.

Taxes, withholding and rollovers

Most of a public pension lump sum is taxable income, because the contributions went in before tax. The IRS rollover rules work like this:

• Direct rollover: the plan sends the money straight to an IRA or another employer plan. No tax is withheld and no tax is due until you take money out later.
• Paid to you: the plan must withhold 20% for federal tax. You cannot opt out of this.
• 60-day rollover: you have 60 days from the day you receive a payment to roll it over. To roll over the full amount, you must make up the 20% that was withheld from other money. Any part you don't roll over is taxed, and may also face the 10% early withdrawal tax.

Oregon also withholds 8% for state tax on IAP payments that could be rolled over, unless you file a Form W-4R; nonresidents must file a W-4R to be exempt. Taking a large lump sum in one year can push you into a higher tax bracket and can raise Medicare Part B premiums, which are higher for people with higher incomes. See how pensions are taxed for more.

The 10% early withdrawal tax and its exceptions

Money taken from a retirement plan before age 59½ usually owes an extra 10% tax on the taxable part. The IRS list of exceptions includes several that matter to public employees:

• Age 55: no 10% tax on payments from an employer plan if you leave your job during or after the year you turn 55.
• Age 50 for public safety: the age is 50 for public safety employees of a state or local government (such as police officers and firefighters) and for certain federal law enforcement and corrections officers.
• Governmental 457(b) plans: payouts are not subject to the 10% tax at any age, except amounts rolled in from another type of plan or an IRA. See our 457(b) guide.

The age 55 and age 50 exceptions apply to employer plans, not IRAs. If you roll a lump sum into an IRA and then withdraw before 59½, the exception is lost and the 10% tax can apply. Some retirees under 59½ leave part of the money in the employer plan for this reason.

What to do next

1. Get official numbers. Ask your plan for both the monthly and the lump-sum figures in writing.
2. Read the tax pages. Your plan's payment forms explain withholding and rollover rules. Read them before you sign.
3. Decide where a rollover would go. Open the receiving IRA or plan account before you apply, so the money can move directly.
4. Check your budget. See whether your monthly income covers basic costs; our retirement budget guide walks through it.
