What is the Alabama state income tax rate in 2026?
Alabama taxes income in 3 brackets from 2.00% to 5.00% in 2026; the top rate starts at $3,000 of taxable income for a single filer and $6,000 for a married couple filing jointly. Example: a married couple, both 70, with $40,000 of Social Security, a $30,000 private pension and $30,000 of IRA withdrawals ($100,000 in all; the pension and IRA money split evenly between them) owes $37 of Alabama income tax (0.0% of their income) and $5,087 of federal tax; a single 62-year-old with $24,000 of Social Security, an $18,000 pension and $18,000 of IRA withdrawals ($60,000 in all) owes $429 to Alabama and $4,111 federal. The schedule, how Alabama treats each kind of retirement income, and its local taxes follow.
| Rate | Single | Married filing jointly |
|---|---|---|
| 2.00% | $0 to $500 | $0 to $1,000 |
| 4.00% | $500 to $3,000 | $1,000 to $6,000 |
| 5.00% | over $3,000 | over $6,000 |
How Alabama taxes retirement income in 2026
| Standard deduction or personal exemption | $3,000 single, $8,500 married filing jointly, $5,200 head of household. Personal exemption, subtracted in addition: $1,500 single, $3,000 MFJ, $3,000 head of household. (Alabama Department of Revenue; rules) |
|---|---|
| Social Security | Social Security benefits are fully exempt: none of the federally taxable amount enters the state base. (Alabama Department of Revenue; rules) |
| Pensions, annuities and IRA/401(k) withdrawals | Pension, annuity and IRA/401(k) distributions: up to $6,000 excluded per taxpayer ($12,000 on a joint return) at age 65 or older. (Alabama Department of Revenue; rules) |
| Government pensions | Employer (defined-benefit) pension dollars, public or private, are fully exempt. IRA and 401(k) dollars keep the capped treatment above. (Alabama Department of Revenue; rules) |
| Capital gains | Net long-term gain is taxed as ordinary income. Short-term gains are ordinary income. (Alabama Department of Revenue; rules) |
Local income taxes: none in Alabama. The local income taxes the tax engine computes for 2026 are in Delaware, Indiana, Iowa, Kentucky, Maryland, Michigan, Missouri, New York, Ohio, Oregon and Pennsylvania.

In our 510,000-path Monte Carlo study of 30-year retirement outcomes, Alabama retirees finished at 73.79% success rate (ranked #25 of 51 by success rate, #30 of 51 by lowest median lifetime state tax). Median 30-year state-tax cost: $63,000 — that is $63,000 more than a Wyoming retiree pays. Median terminal balance after 30 years: $870,269. State tax is part of the optimization here — the playbook below shows the federal-state-ACA stack.
The AL verdict
For a retiree planning withdrawals in 2026, Alabama is broadly retirement-tax-friendly, with most distributions sheltered. Exempts social security, taxes 401(k) and ira withdrawals, no estate tax.
Alabama allows a retirement-income exclusion of up to $12,000 for a couple from age 65. A traditional→Roth conversion draws on that same exclusion from age 65, so converting inside the cap can cost nothing at the state level.
Worked example: $30k Roth conversion in Alabama
Consider a married couple age 58 in Alabama with $75,000 of ordinary income (their MAGI), both on ACA Marketplace coverage. They want to convert $30,000 from a traditional IRA to a Roth. The Alabama state tax on that conversion is approximately $1,500 — Alabama's $12,000 retirement-income exclusion does not extend to conversion income at this age, so the full amount is taxed at 5.00%. Federal income tax adds another $3,600 — the whole conversion is taxed in the federal 12% bracket. And because the conversion pushes their MAGI to $105,000 — over the 400% FPL cliff of $84,600 — they lose their full ACA premium tax credit, $23,393 a year at Alabama's average benchmark Silver premium. Total cost of the $30,000 conversion: about $28,493, or an effective 95.0% marginal rate. That state figure uses Alabama's top bracket rate, so read it as a ceiling: a household whose income lands in a lower bracket pays less, and Alabama's own deductions reduce it further. The federal-state-ACA stack matters in Alabama.
Cost breakdown
| Component | Amount |
|---|---|
| Federal income tax (12% bracket) | $3,600 |
| Alabama state income tax | $1,500 |
| ACA premium tax credit clawback | $23,393 |
| Total cost on $30,000 conversion | $28,493 (95.0% effective) |
Scenario B (friendly): $50k post-65 conversion in Alabama
A married Alabama couple age 67, both on Medicare, with $40K pension income converts $50,000 in a single year. State tax owed: $1,900 — $12,000 of it fits inside Alabama's $12,000 exclusion for a couple at this age (this assumes no other retirement distribution is drawing on that cap in the same year), leaving $38,000 taxed at 5.00%. Federal income tax added: $4,607 ($7,500 of the added income fills deductions their pension left unused and the rest is taxed in the federal 10%–12% brackets). No ACA clawback (on Medicare). Total: $6,507, or 13.0% effective. The post-65 conversion window is where a Alabama ladder is cheapest.
What the Monte Carlo data says about Alabama
QuantCalc Research ran a 30-year, 10,000-path Monte Carlo simulation for an identical representative retiree (age 60, $2M starting balance, 60/40 portfolio, $80K real annual spend) in each of the 51 U.S. jurisdictions. Here's how Alabama compared to the best- and worst-case states:
| Metric | Alabama | Wyoming (best) | California (worst) |
|---|---|---|---|
| 30-year success rate | 73.79% | 77.11% | 69.03% |
| Rank (of 51) | #25 | #1 | #51 |
| Median lifetime state tax (30y) | $63,000 | $0 | $154,980 |
| Median total tax (30y) | $281,400 | $218,400 | $373,380 |
| Median terminal balance | $870,269 | $999,751 | $695,612 |
| Δ success vs Wyoming | -3.32 pp | — | −8.08 pp |

How Alabama treats capital gains in retirement
Alabama taxes long-term capital gains as ordinary income at the same top bracket rate (5.00%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 5.00% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
Why the ACA cliff hits hard in Alabama
The 400% federal-poverty-level cliff is federal, not state-specific — but its dollar impact depends on the benchmark Silver-plan premium in your county. Alabama's Marketplace pricing and your household composition determine the size of the subsidy at risk. A couple aged 58 with MAGI of exactly $84,600 still has $22,437 a year of premium tax credit at Alabama's average benchmark Silver premium, and all of it is on the line. With the 2021–2025 enhanced credit expired, $1 of additional MAGI above 400% FPL eliminates the entire credit.
For 2026 the 400% FPL threshold is:
- Household of 1: $62,600
- Household of 2: $84,600
- Household of 3: $106,600
- Household of 4: $128,600
Roth conversion strategy for Alabama
The AL-specific playbook depends on tier:
- Identify your cliff distance. Compute MAGI from all income sources (wages, capital gains, interest, dividends, traditional withdrawals). Find your headroom under 400% FPL. Use the live cliff widget above for a quick check.
- Stay under the cliff if you can. In Alabama at 5.00%, the marginal cost of going over the cliff is federal tax + state tax + full PTC clawback. The break-even conversion size is smaller than in tax-free states.
- If you must go over, convert big. Once you've crossed the cliff, additional conversion dollars only cost federal + state tax (no incremental PTC loss). A "rip the bandage" conversion year can be efficient if you have many traditional dollars to move.
- Coordinate with capital gains and the 0% LTCG bracket. Alabama taxes long-term capital gains as ordinary income at the same top bracket rate (5.00%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 5.00% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
- Plan ahead for IRMAA. The IRMAA Medicare premium surcharge has a 2-year lookback. A Alabama resident in their early 60s converting today will see IRMAA implications at 65. See RMD + IRMAA calculator for the lookback math.

Run a free simulation →What a year-end move does to your Alabama and federal tax in 2026
Each move changes three bills at once: the federal return, the Alabama return and, for anyone on Medicare, the IRMAA surcharge the 2026 income sets for 2028. Example: a married couple, both 72, with a $40,000 pension, $50,000 of Social Security, a $30,000 IRA withdrawal and $10,000 of long-term gains already realized in 2026, the pension, the IRA money and the conversion split evenly between them on the state return. Each row is that year with one move made, against the same year without it (negative = less tax).
| Move (by December 31, 2026) | Federal tax | Alabama tax | IRMAA in 2028 |
|---|---|---|---|
| Convert $25,000 to a Roth IRA | $3,165 | $1,223 | $0 |
| Send $10,000 of the IRA withdrawal to charity as a QCD | −$1,200 | −$416 | $0 |
| Harvest a $5,000 loss against the year's gains | $0 | −$276 | $0 |

Federal tax comes on top: $5,087 and $4,111.
Does Alabama tax Social Security benefits?
No. Social Security benefits are fully exempt: none of the federally taxable amount enters the state base. (Alabama Department of Revenue; rules)
Does Alabama tax pensions, 401(k) and IRA withdrawals?
Pension, annuity and IRA/401(k) distributions: up to $6,000 excluded per taxpayer ($12,000 on a joint return) at age 65 or older.

Does Alabama tax Roth conversions?
Alabama taxes Roth conversions as ordinary income at the state level. A $30,000 conversion by a couple aged 58 costs about $1,500 in state tax alone — Alabama's $12,000 retirement-income exclusion does not extend to conversion income at this age, so the full amount is taxed at 5.00% — on top of federal tax and any ACA subsidy clawback. That state figure uses Alabama's top bracket rate, so read it as a ceiling: a household whose income lands in a lower bracket pays less, and Alabama's own deductions reduce it further.
What is Alabama's 30-year Monte Carlo retirement success rate?
In QuantCalc's 510,000-path Monte Carlo study, a representative retiree in Alabama (age 60, $2M balance, 60/40 portfolio, $80K real spend) finished 30 years at 73.79% success rate — ranked #25 of 51 jurisdictions. Median 30-year state tax: $63,000. Median terminal balance: $870,269.
What is the ACA cliff in Alabama for 2026?
The ACA premium-tax-credit cliff is a federal threshold, not state-specific. For a household of two in 2026, it sits at 400% of the federal poverty level — $84,600. Crossing it by even $1 of MAGI eliminates the full subsidy now that the 2021-2025 enhanced credit has expired.
Is Alabama a good state to retire for tax purposes?

Does Alabama have a state estate or inheritance tax?
No — Alabama does not impose a state-level estate or inheritance tax.
How does Alabama tax capital gains?
Alabama taxes long-term capital gains as ordinary income at the same top bracket rate (5.00%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 5.00% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
