What happens if I file my tax return after the due date?
You'll be penalized with a late-filing penalty of at least $50… even if you are only one day late. To avoid this penalty, make sure your envelope is postmarked by the due date.
How long do I need to keep my records?
You must maintain your records for a period of four years from the due date, or the date that you filed your IFTA return (Form RMFT-15), whichever is later, to substantiate the information reported on the return.
