Alabama does not tax Social Security income. Every dollar of Social Security retirement, disability, or survivor benefits is fully exempt from Alabama state income tax under Code of Alabama ยง 40-18-19.1Alabama Legislature. Alabama Code 40-18-19 – Exemptions – Generally The federal government is a different story, and so are some of your other retirement checks.
What Alabama’s Exemption Actually Covers
Alabama Administrative Code Rule 810-3-19-.01(c) states that all amounts received under the federal Social Security Acts are totally exempt from Alabama income tax.2Cornell Law School. Alabama Admin Code Rule 810-3-19-.01 – Exempt Retirement Allowances That means every category of Social Security payment is covered:
- Retirement benefits based on your work history
- Disability benefits
- Survivor benefits paid to a deceased worker’s family
There are no income caps or phase-outs on the state side. It doesn’t matter how much you earn from pensions, investments, or part-time work; your Social Security stays exempt in Alabama.
One small boundary worth knowing: some Alabama cities levy occupational license taxes on income earned within their limits. Those taxes apply to wages and active earnings, not to retirement payments, so your Social Security check isn’t swept into a local tax either.
Your Federal Return Is a Separate Question
Alabama’s exemption only reaches state tax. The IRS can still tax a portion of your Social Security based on your “combined income,” which is your adjusted gross income plus any nontaxable interest plus half of your Social Security benefits.
For single filers:
- Combined income of $25,000 to $34,000: up to 50 percent of your benefits are taxable
- Combined income above $34,000: up to 85 percent of your benefits are taxable
For married couples filing jointly:
- Combined income of $32,000 to $44,000: up to 50 percent of your benefits are taxable
- Combined income above $44,000: up to 85 percent of your benefits are taxable
These thresholds have not been adjusted for inflation since they were set in the 1980s and 1990s, so more retirees cross them each year. If you’re married filing separately and lived with your spouse at any point during the year, the base amount drops to zero, which means nearly all of your benefits are subject to federal tax.3Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits
How Alabama Treats Your Other Retirement Income
Social Security isn’t the only retirement income Alabama leaves alone, but the rules split by plan type.
Pensions and Defined Benefit Plans
Traditional pension payments are generally exempt from Alabama income tax, whether the pension came from a public or private employer. The statute specifically names the Alabama Teachers’ Retirement System, the Alabama Employees’ Retirement System, the federal Civil Service Retirement and Disability Fund, and the Tennessee Valley Authority pension system.1Alabama Legislature. Alabama Code 40-18-19 – Exemptions – Generally The administrative rule extends the exemption to all defined benefit plans as defined by federal tax law, including nonqualified plans such as supplemental executive retirement plans.4Cornell Law School. Alabama Admin Code Rule 810-3-19-.04 – Defined Benefit Plans
Military Retirement
All military retirement pay is exempt from Alabama income tax, along with survivor benefits derived from military retirement. The full exemption has been in place since January 1, 1989.5Alabama Legislature. Alabama Code 40-18-20 – Exemptions – Military Retirement Benefits
401(k)s, IRAs, and Other Defined Contribution Plans
This is where the picture changes. Distributions from 401(k)s, traditional IRAs, SEP IRAs, and similar defined contribution accounts are subject to Alabama income tax.6Alabama Department of Revenue. Income to Be Reported on the Alabama Income Tax Return The difference comes down to how the plan works: a defined benefit plan promises a set monthly payment, while a defined contribution plan is an individual account that grows with investment performance.
If you’re 65 or older, you catch a break. Beginning January 1, 2023, the first $6,000 of taxable retirement income from defined contribution plans is exempt from Alabama income tax, and that exemption is scheduled to increase to $12,000 starting in 2026.1Alabama Legislature. Alabama Code 40-18-19 – Exemptions – Generally Amounts above the exempt threshold are taxed at Alabama’s regular graduated rates.
Property Tax Relief Can Follow From Your Social Security Status
Because Alabama excludes Social Security from state adjusted gross income, many retirees whose primary income is Social Security end up under the $12,000 AGI threshold that unlocks the state’s senior property tax breaks, even when their actual Social Security benefits are higher than that.
For homeowners 65 and older, the homestead rules work in tiers:
- State AGI under $12,000: exempt from all state property taxes, plus a $5,000 reduction in assessed value for county taxes, including school district taxes.
- Combined federal taxable income under $12,000: may qualify for a complete exemption from all state, county, and municipal property taxes on your homestead up to 160 acres.
- Income above $12,000: still exempt from the state portion of property taxes, with the regular $2,000 homestead reduction in assessed value for county taxes.

Reporting Social Security on Your Alabama Return
Exempt doesn’t mean invisible. Alabama uses Social Security information to reconcile with federal reporting and to confirm the exemption is applied correctly. Exempt Social Security income is typically reported on Alabama Schedule RS (Retirement Schedule), which separates taxable from nontaxable retirement income.
The common mistake is leaving exempt Social Security or pension income off the return entirely. That can prompt a notice from the Alabama Department of Revenue asking for clarification. Report the income, subtract the exempt portion, and the return processes cleanly.
