you may want to check the Alabama Dept of Revenue website. many states have provisions to pay electronically using checking, savings, debit or credit card through their website. probably a fee for debit or credit card free for checking or savings. what's more they allow to set up future payment so if payment is due 7/15/2020 you can set it up now to be taken out on that date.- you'll be able to print documentation that shows you've done.
note that the actual withdrawal or charge may be a couple of days later but you are not charged for late payment
this this avoids the need to mail in the payment.
