Q. My wife has a disability retirement from the Postal Service. She is deemed permanently and totally disabled by the Social Security Administration and receives the SSA disability benefit. She also receives a FERS disability annuity benefit. Is the FERS disability annuity federally taxable? If not, can you direct me to the IRS document that outlines how to file?
A. It is taxable unless the Internal Revenue Service determines that she is totally disabled. You can call them at 1-800-829-4933.
