Filed our taxes (married, filing jointly) back in April with no issues. This week we received a notice from the State of Alabama stating that we owe an additional $45 on top of the $1800 we've already paid. There was no explanation for the adjustment. I've reached out to the Alabama Dept. of Taxation for additional information, but they have yet to respond. We have 10 days to make payment. Do I have any recourse here?
