Does Oklahoma Tax all of my retirement income?
Civil Service Retirement in Lieu of Social Security..
Each individual may exclude 100% of their retirement benefits received from the Federal Civil Service Retirement System (CSRS), including survivor benefits, paid in lieu of Social Security
Note: Retirement benefits paid under the Federal Employees Retirement System (FERS) do not qualify for this exclusion. However, for retirement benefits containing both a FERS and a CSRS component, the CSRS component will qualify for the exclusion. Provide substantiation for the CSRS component, such as a copy of your Notice of Annuity Adjustment.
See either Schedule 511-A in the Oklahoma Resident Packet 511 or Schedule 511NR-B in the Oklahoma Nonresident/Part-Year Resident Packet 511NR
