Alabama Retirement Income Tax Calculator

Retirement income tax calculation for Alabama. Social Security is taxable at the federal level if combined income exceeds $25,000 (single) or $32,000 (married) — up to 85% may be taxed. This calculator excludes Social Security benefits from the STATE-taxable base entirely (many states exempt Social Security regardless of their general income tax treatment; this is a simplifying assumption, not a state-by-state verified exclusion list). Pension and 401(k)/IRA income is state-taxable ordinary income except the amount you enter as excluded by your Alabama return. Alabama's real progressive brackets (up to 5%) are applied marginally to pension/IRA/other retirement income. Alabama may exclude part of pension and retirement-plan income; this page does not model that rule. The calculator subtracts the amount you enter as excluded by your Alabama return (capped at the pension and IRA income entered) before the Alabama tax is figured. Federal tax uses the final 2026 brackets and standard deduction from IRS Revenue Procedure 2025-32, plus the section 63(f) additional standard deduction for age 65+ — $2,050 for a single filer and $1,650 per qualifying spouse (so $3,300 when both spouses are 65+ on a joint return). It does NOT apply the separate enhanced deduction for seniors under 26 U.S.C. §151(d)(5)(C) ($6,000 per qualified individual age 65+, claimed on Schedule 1-A Part V and phased out by 6% of MAGI over $75,000 single / $150,000 joint, available for tax years beginning before January 1, 2029). If you and your spouse are both 65+ and under that phase-out, the unmodelled deduction is worth up to $12,000 of additional federal deductions, so the federal tax shown here is deliberately CONSERVATIVE (too high) rather than optimistic — use the dedicated senior deduction calculator to model it.
