Alabama State Tax Calculator (2026)

How Alabama taxes income

Alabama charges 2% to 5%. State tax is a separate calculation from your federal return rather than a share of it — Alabama sets its own schedule and its own definition of taxable income.

• Top marginal rate: 5%, reached at $3,000 for a single filer
• Brackets: 3 graduated bands, starting at 2%
• Standard deduction: $3,000 single / $8,500 joint
• Personal exemption: $1,500 single, $3,000 joint, $1,000 per dependent (not applied here)

Rate figures are as of January 1, 2026 and come from the published Tax Foundation compilation; they have not been independently checked against Alabama Department of Revenue. States do change rates mid-year, so confirm a figure there before relying on it.

What catches people out in Alabama

• Alabama has 3 brackets for a single filer, running from 2% on the first dollar up to 5% above $3,000.
• Alabama doubles every bracket floor for joint filers, so a married couple is taxed the same as two single filers on the same combined income and the schedule carries no marriage penalty.
• The Alabama standard deduction is $3,000 for a single filer and $8,500 for a couple filing jointly. It is a separate figure from the federal standard deduction and usually much smaller, so itemising is a decision you make once federally and again for the state.
• Local income taxes are excluded. Alabama's average local rate is 0.07% of AGI (footnote a). Alabama also allows some or all of federal income tax paid to be deducted from state taxable income (footnote b), which this calculator does not model. The standard deduction shown applies below an AGI threshold and phases down above it (footnote c).

What this estimate leaves out

Three things are deliberately outside this calculation, because they change more often than annually and a confident wrong number does real damage on a tax page.

• The personal exemption — $1,500 single, $3,000 joint, $1,000 per dependent — is not applied, so the figure runs slightly high.
• Local and city income tax is not included. New York City is the significant one nationally.
• State-specific credits, subtractions and income addbacks are out of scope and can move the result either way.

If you have income in India, Alabama is where treaty relief runs out

States are not parties to the India-US tax treaty, and a state credit for "taxes paid to other jurisdictions" almost always means other US states rather than other countries.

So NRO interest, Indian rental income or a gain on Indian shares can be taxed by Alabama with no credit for the Indian tax deducted at source — even though Form 1116 largely neutralises that same tax federally.

The treatment is not uniform across states, so treat this as the general position rather than as Alabama's confirmed one, and check the credit rules with Alabama Department of Revenue before relying on relief.
