More than likely your defined benefit retirement plan is not taxable in Alabama. The following are not taxed by Alabama:
Social Security, military, civil service, state/local government and
qualified private pensions are exempt. All out-of-state government
pensions are tax-exempt if they are defined benefit plans.
For more information, see page 7 of: http://revenue.alabama.gov/incometax/2016_forms/16f40bk.pdf for a list of types of income you do NOT report in Alabama.
