Picture a recently retired Navy officer who hung up the uniform at 42 and took a senior program manager role on the civilian side paying around $165,000 a year. He’s fortunate enough to collect a $48,000 military pension on top of it. His Thrift Savings Plan sits at $1.3 million, his wife works part-time, and he files taxes jointly. Total ordinary income is roughly $213,000, and he plans to leave the civilian job at 65.
On paper, he seems set for life. But a surprise comes at tax time, when he realizes his pension and his paycheck are not taxed the same way.
The Three Layers, Stacked on One Income
The first layer is federal income tax. His pension is fully taxable at the federal level, just like his W-2. With the 2026 standard deduction for married filing jointly at $32,200, his taxable income lands just inside the 24% bracket, which runs from $211,400 to $403,550 for joint filers. He is roughly one bonus or one spouse raise away from pushing the next dollar into the 32% bracket that begins at $403,550.
The second layer is state income tax, and this is where most people get tripped up. Military retirement pay is treated very differently across states. Some exempt it entirely, others tax it like any other pension, and a handful sit in the middle with partial exclusions or age-based carve-outs. Military retirees need to look up their specific state’s rule before assuming the pension is “tax free” just because someone at the squadron reunion said so.
The third layer is FICA. Social Security and Medicare payroll taxes apply to the civilian W-2 wages but not to the pension and not to TSP withdrawals.
At 62, he is sitting at the top of his lifetime earning years. At 65, when the W-2 disappears, his ordinary income drops by about $165,000 overnight. The pension keeps coming. The TSP just sits there compounding. Required minimum distributions do not start until 73 under current rules.
That gap, from full retirement at 65 to the start of RMDs, is a tax planning window measured in hundreds of thousands of dollars of lifetime liability. Every dollar pulled from the traditional TSP while the W-2 is still flowing is taxed at 24% federal. Every dollar pulled or converted between 65 and 73 could be taxed at 12% or 22% instead, depending on how the household structures income.
The Strategy Most Officers in This Position Should Consider
Do not touch the TSP while still working, experts advise. Live off the paycheck and pension, max the TSP if cash flow allows, and let the balance grow.
Plan Roth conversions for the 65-to-72 window. Once the civilian salary stops, taxable income falls hard. Converting $50,000 to $100,000 per year from the traditional TSP (or a rollover IRA) into a Roth fills up the 12% and 22% brackets at a fraction of today’s marginal rate. But watch IRMAA, the Medicare premium surcharge that kicks in once Part B starts.
Consider rolling the TSP to an IRA before age 70.5 if charitable giving is part of the plan. Qualified Charitable Distributions are available from IRAs, not directly from the TSP, and they count toward RMDs while skipping federal income tax entirely.
What to Act on First
Pull the most recent pay stub and last year’s return side by side. Confirm which bracket the next dollar falls into, verify your state’s military pension rule on the state revenue website, and map out what total income looks like at 66, when only the pension and any Social Security are running. That picture, more than any rule of thumb, tells you whether to convert, defer, or sit still.
The common mistake is starting TSP withdrawals at 62 or 63 “to get ahead of RMDs.” Done while the W-2 is still active, it is the most expensive way to touch that money. If the household estate is approaching the 2026 federal estate exclusion of $15 million, a fee-only CPA who handles military retirees is worth the engagement letter.
