Quarterly Tax Estimator for Alabama

Quarterly estimated payments in Alabama must cover both your federal and state obligations. Alabama uses graduated rates (2-5%), and most states require their own quarterly payment schedule that may differ from the IRS dates. If your Alabama locality imposes income tax, you may need a third set of quarterly payments. This estimator pre-loads Alabama's tax rates so you can calculate both federal and state quarterly amounts in one place, avoiding underpayment penalties at both levels.

Alabama uses a graduated income tax with brackets ranging from 2-5%. Lower income is taxed at lower rates, with the 5% top rate applying only to income in the highest bracket. This progressive structure means your effective state tax rate is always lower than the top marginal rate. In addition, some Alabama localities impose their own income tax, which stacks on top of the state rate. This is especially notable in areas like certain cities and counties. Always check your local rate when calculating total tax liability.
