Why was I assessed late fees, penalties, and interest?


Late fees, penalties, and interest will be assessed if Form R-1331 and the sales tax payment are received after the due date.

A tax liability becomes delinquent on the day after the due date. Sales taxes are due and payable to LDR on or before the 20th day of the month following the month in which the purchase was made. If the return is filed late, a delinquent penalty of 5 percent of the tax due for each 30 days, or fraction thereof, of delinquency, not to exceed 25 percent of the tax due.

Interest on the tax liability is assessed from the due date through the payment received date. Refer to Form R-1111, Interest Rate Schedule Collected on Unpaid Taxes, for applicable monthly interest rates that apply. (Question & answer last reviewed July 9, 2024)
