State sales tax
4% state, local averages 9.46% combined
Alabama's state rate is 4%, but cities and counties layer their own tax on top, and Alabama's average local add-on of 5.46% is the highest in the country, pushing the average combined rate to about 9.46%. Some jurisdictions levy as much as 8% locally on their own, and Alabama splits collection between the Department of Revenue and self-administered localities, so one store can owe returns to more than one authority. Storeveu holds the combined rate at the store level so each register applies the exact rate for its address.
