Advance Payment System (APS): Quarterly Tax for Mauritian Companies
How APS works, who is caught, and how to avoid the 5% penalty for underpayment.
Who must pay APS?
Companies with gross income above Rs 10 million in the preceding year must pay quarterly instalments based on prior-year profits or current-year estimate.
Choosing your basis
You can pay based on last year's tax (safer) or estimated current-year tax (better for cashflow if profits are falling). Underestimate and you're penalised.
Deadlines
APS is due by the end of the second month following each quarter — end of Aug, Nov, Feb, May for June year-ends.
The trap
Estimating too low triggers a 5% penalty on the underpayment. Rule of thumb: match at least 75% of ultimate liability across the four instalments.
