Does Missouri Tax Federal Pensions (FERS, CSRS)? 2026

Updated October 29, 2026. Quick answer: Yes, up to a cap. “Public pensions are pensions received from any federal, state, or local government.” The 2025 Form MO-A subtracts them up to $47,633, less any Social Security exemption claimed.

What Missouri does with a FERS or CSRS annuity

QuestionWhat the Missouri documents say
What the source saysMissouri treats a pension from the federal government as a public pension, and the taxable part is subtracted from Missouri income up to a cap tied to the maximum Social Security benefit, which is $47,633 on the 2025 Form MO-A, less any Social Security exemption claimed.
Amount or limitPublic pensions (federal, state, or local government) are exempt up to $47,633 (the maximum Social Security benefit figure printed on the 2025 Form MO-A), reduced by any Social Security exemption claimed on the same lines; the statute sets the exemption at one hundred percent of non-private retirement benefits subject to that cap.

In the Missouri documents’ own words

  • “Amount from Line 1 or $47,633 (maximum social security benefit),” (Form MO-A, Individual Income Tax Adjustments, 2025)
  • “Amounts from Line 6Y and 6S or $6,000, whichever is less” (Form MO-A, Individual Income Tax Adjustments, 2025)
  • “one hundred percent of the retirement benefits received from sources other” (RSMo 143.124, Annuities, pensions, retirement benefits, or retirement allowances provided by state, United States, political subdivisions or any other state)
  • “six thousand dollars of any retirement allowance received from any privately funded” (RSMo 143.124, Annuities, pensions, retirement benefits, or retirement allowances provided by state, United States, political subdivisions or any other state)

How this differs from other pensions in Missouri

Private pensions, annuities, IRAs, and 401(k) plans funded by a private source get a much smaller exemption, capped at $6,000 per person on Form MO-A, while public pensions including federal ones use the $47,633 cap. The statute also states that from 2024 the maximum exemption applies regardless of filing status or Missouri adjusted gross income. See also Does Missouri tax pensions? and military retirement pay.

FERS, CSRS and your TSP

The state documents cited here do not name TSP withdrawals; the statute includes 401(k) plans and IRAs (not Roth IRAs) in its definition of retirement allowance, and the form places those funded by a private source on the private pension calculation. For the Thrift Savings Plan itself, see Does Missouri tax TSP withdrawals? and the TSP calculator.

What the Missouri documents leave open

None of the Missouri documents names CSRS, FERS or the TSP, so the federal rule rests on the any-government definition of a public pension. Form MO-A prints the $47,633 cap without saying how it is indexed, and only the 2025 form was read, so check the 2026 form when it appears.

Common mistakes

  • Using the $6,000 private pension deduction for a federal pension. A pension from the federal government is a public pension under the instructions, which use the much larger cap.
  • Forgetting that the cap is reduced by any Social Security exemption claimed on the same lines.
