MRA Penalties & Interest: How Much Non-Compliance Really Costs

The MRA operates a two-part regime: a penalty for late or non-filing, and interest on unpaid tax. They stack, they compound and they can dwarf the original liability within a year.

Late filing penalty

A monthly penalty (currently MUR 2,000) applies for each month or part-month the return is outstanding, capped at a statutory maximum.

Late payment interest

Interest accrues at a monthly rate on unpaid tax, computed from the original due date until settlement.

Under-declaration

Where MRA reassesses income upward, penalties of up to 50% of the additional tax may apply where negligence or wilful default is established.
