Tax strategy, decoded.
There is no special federal tax break in retirement. The FERS pension is taxable, most of Social Security is taxable, and every Traditional TSP dollar is taxable. But the federal retirement tax picture is predictable — and predictable means plannable. Here’s the full guide, current to 2026.

The numbers that anchor 2026
A few figures shape almost every federal retirement tax decision this year:
- ~95% — the share of a typical FERS pension that is taxable at the federal level
- Age 73 — when required minimum distributions begin for retirees born 1951–1959
- $6,000 — the OBBBA senior deduction per person 65+, available 2025–2028
- $109,000 / $218,000 — the 2026 IRMAA first threshold, single and married filing jointly
- 13 — states where a federal retiree’s core retirement income faces no state income tax
The anchor.
What arrives whether you plan or not.

IRMAA is the Medicare premium surcharge that turns one dollar of extra income into a four-figure cost. The 2026 brackets, the two-year MAGI lookback that ambushes new retirees, the cliff effect, what counts as MAGI, and the SSA-44 appeal most retirees never file.
RMD Strategy for Federal Retirees: The Age 73 Tax Stack
At 73, required minimum distributions begin and stack on top of the pension and Social Security. The calculation, the first-year April 1 trap that forces two RMDs into one year, the TSP “still working” exception, and why Roth TSP is now RMD-exempt since 2024.

The gap between retirement and the first RMD at 73 is the lowest-tax stretch most retirees will ever see. The bracket-filling method, the two ceilings (tax brackets and IRMAA), the TSP in-plan conversion option launched in 2026, the five-year rule, and an honest look at who should and shouldn’t convert.
