Interest & Penalties

Interest and Penalties 

Mississippi law requires reports to be filed, and taxes to be paid, on or before the end of the month following the close of the calendar quarter reported.
Interest is calculated at 1 percent per month on any portion of a month in which the payment is past due, and continues to accrue until all taxes, penalties and interest are paid.
Penalties are charged in addition to interest.
A penalty for late filing is charged beginning 30 days after the due date of the report. The amount of penalty for late reporting is an additional 10 percent of tax due.
An additional penalty for late payment is charged 60 days after due date or when a warrant for collection is issued.  The amount of this penalty is 10 percent of tax due.  Total penalties generally will not exceed 20 percent for any calendar quarter.
