Do I have to make Alabama estimated tax payments?
Alabama requires estimated payments once you expect to owe $500 or more in state income tax for the year. The state form is Form 40ES. Payments can be made online through My Alabama Taxes. Filing and paying federal estimated tax does not cover the state amount — they are separate payments.
Where do I pay Alabama estimated taxes online?
Alabama accepts online estimated tax payments through My Alabama Taxes, run by the Alabama Department of Revenue. Federal payments go through IRS Direct Pay or EFTPS separately.
What happens if I underpay estimated taxes in Alabama?
The IRS charges an underpayment penalty based on the amount underpaid and the number of days late. Paying at least 90% of this year's tax or 100% of last year's (110% if your AGI exceeded $150,000) meets the federal safe harbour. Alabama applies its own interest and penalty on late or short state payments.
State payments are administered by the Alabama Department of Revenue via My Alabama Taxes.
