In accordance with Section 40-1-44, Code of Alabama 1975, the interest rate must be used to compute interest on any tax or other amount due, other than property tax, not remitted by the due date.
To calculate the interest due, first, determine the number of days that the registrant is delinquent, and locate the corresponding percentage factor on the interest chart for that number of days. Second, multiply the factor times the registration fee due to determine the amount of interest due.
