Which TSP installment payments work best around a military pension?

Monthly checks are the safest way to draw the TSP

Frequency changes cash flow, not tax. A $24,000 yearly draw is $2,000 monthly, $6,000 quarterly or $24,000 in one annual installment, and every version adds the same $24,000 of ordinary income to the same tax year.

Your retired pay from DFAS already arrives monthly, so a monthly TSP installment mostly copies that rhythm. If the bills are covered by the pension, you gain nothing by matching it. An annual installment puts the year's taxable amount on one line of the TSP Form 1099-R, and it's simpler to resize every year.

Edgepoint Wealth Management works in the income-first order. We set the yearly dollar target from your pension and tax tiers, then pick the frequency that fits your bills. Investments come after that.

A life-expectancy payment is the tax-smart choice

Not automatically. The TSP computes a life-expectancy installment by dividing your balance by an IRS life expectancy factor, and it recalculates every year. Payments tend to rise as you age and as the balance grows, so you don't control how much taxable income lands in a given year.

A fixed dollar installment lets you aim at a number, such as staying under an IRMAA tier (Medicare's income-based surcharge on Part B) in the year you turn 63. The TSP lets you change the amount or frequency, or stop installments, at any time. That flexibility is the tax tool.

Life-expectancy installments still earn their place before age 59½. They are one of the exceptions to the 10 percent early withdrawal penalty, which matters if you left the service before 55 and need money now. Check the TSP tax notice for your case.

Spreading income draws evenly keeps the tax bill lowest

Sometimes, but be honest about shift versus save. Timing traditional TSP dollars mostly moves income tax to another year, and it saves money only when the earlier year has the lower rate. IRMAA is different. It's a cliff, so $1 over a tier costs the whole tier for that year, and avoiding it is a real saving.

Single or married changes the math. The first IRMAA tier ends at $109,000 of MAGI (modified adjusted gross income, roughly your income line plus a few add-backs) for a single filer and $218,000 for a joint return. A divorced or widowed retiree hits a surcharge at half the income of a couple.

How much sits in the account counts as well. A $300,000 TSP rarely pushes anyone into a new tier. A $900,000 traditional balance left alone can produce very large required minimum distributions later.

So does your retirement date. Leaving a second career at age 60 gives you 3 low-income years before the age-63 lookback year. Working to age 65 gives you none.

Early or late retirement

Omar's rental condo and $121.70 a month at age 65

Omar, a hypothetical retired Army colonel, is 57, single, and earns $180,000 as a consulting director. He inherits a paid-off condo that nets $24,000 a year in rent, and he plans to leave consulting at 60. His pension is $96,000 a year (about $8,000 a month), so pension plus rent gives $120,000 before any TSP money. He doesn't need the TSP to pay bills.

Option A is monthly fixed installments of $2,000 from age 60 through 64. That is $24,000 a year and $120,000 in total. His age-63 MAGI is $120,000 + $24,000 = $144,000, which falls in the tier up to $171,000, so Part B at 65 costs $405.80 a month.

Option B is annual installments of $40,000 at ages 60, 61 and 62, also $120,000 in total, then a pause at 63 and 64. His age-63 MAGI is $120,000, which falls in the tier up to $137,000, so Part B at 65 costs $284.10.

B saves $121.70 a month at 65, and again at 66 because the age-64 lookback is also $120,000. That's $121.70 × 24 = $2,920.80 in total. The income tax on the $120,000 isn't saved. It moves into ages 60 to 62, when his MAGI is $160,000.

With $40,000 a year from a $900,000 balance, the installments are expected to last over 20 years, so Omar elects his own withholding instead of the 20 percent mandatory rate. The TSP funds paying these installments can fall in value, sometimes for years, and no payout schedule is guaranteed.

The example ignores income tax brackets, which change, and it assumes steady rent and the current IRMAA tiers. It doesn't cover Roth conversions. A retiree who needs TSP money for monthly bills has much less room to move installments between years. Our calculator runs this kind of comparison with your own numbers.

The two schedules

What it saves and what it only moves

20 percent withholding means the TSP keeps a fifth

Withholding is a prepayment, not the tax itself. A $10,000 partial withdrawal nets $8,000, with $2,000 sent to the IRS and credited on your Form 1040. You get a refund if your real rate is lower and owe more if it's higher. The 20 percent is mandatory only for partial withdrawals and installments expected to last under 10 years.

6 dates from separation to age 75, in calendar order

First comes separation, when installments and partial withdrawals open up (partials of at least $1,000, no more often than every 30 days). Next is age 59½, when the 10 percent penalty stops applying. Age 63 is the MAGI year that sets Part B at 65.

Age 65 brings Part B, which you need to keep TRICARE For Life, along with any IRMAA tier. Required minimum distributions, the IRS-mandated yearly draws, start at age 73, or age 75 if you were born in 1960 or later. Every January, Forms 1099-R arrive from the TSP and DFAS.

Starting too early hurts. Installments at 57 while still earning $180,000 stack TSP income on top of $276,000 of pay and pension. Waiting too long hurts as well: never touching the TSP lets the balance grow into forced income draws that land on top of the pension (worked in the next section).

Order matters most. Pausing installments at 64 instead of 63 misses the lookback year that prices Part B at 65. Medicare uses MAGI from 2 years earlier, so the deadline for trimming income is the end of the calendar year you turn 63.

Setting up monthly installments and leaving them alone, the "automate it and forget it" advice taken literally, kept Omar's $2,000 a month running through ages 63 and 64. His Part B at 65 and 66 then cost $405.80 instead of $284.10 a month, $2,920.80 over the 2 years, for income he never needed.

Moving the amount changes the tier, not the rule: if Omar's pension or rent were higher, the same pause would protect a different tier.

The dates

Three timing errors

How much will the first RMD be if the TSP sits untouched?

If Omar leaves $900,000 untouched and it grows 5 percent a year, for illustration only, his first RMD at age 75 lands near $87,000. That's the balance grown to about $2.17 million, divided by a rough IRS factor of 25 at that age.

Here are the steps you can repeat. Start with $900,000. Eighteen years to age 75 multiplies the balance by about 2.41 (1.05 to the 18th power), giving about $2.17 million. Divide by 25 and you get roughly $87,000.

Now add his pension and rent: $87,000 + $96,000 + $24,000 = $207,000 of MAGI. That's above the $205,000 single tier, so Part B would cost $649.20 a month under the current table. TSP installments taken in earlier years count toward RMDs and shrink this number.

Gather these before you decide. Your TSP balance and installment history are in My Account on tsp.gov. The DFAS Retiree Account Statement is on myPay. Forms 1099-R from the TSP and DFAS arrive each January. Pull your last 2 Form 1040s, with Schedule E for rental income, and your Social Security statement from ssa.gov.

The estimate

Documents to gather

Bring your TSP statement and 1099-Rs to Edgepoint Wealth Management before age 60

The useful time to talk with Edgepoint Wealth Management is the year before second-career pay stops, and no later than the year you turn 62, so the age-63 lookback year can still be shaped. Bring the documents listed in the last section plus an estimate of any rental or other side income. The first conversation can then start from your income numbers before anyone discusses funds.
