Detailed Explanation

## Companies

File the provisional return by the last day of the sixth month and pay half of the estimated tax then and the rest by the end of the twelfth month.

## Individuals

Sole proprietors and partners file by the end of the third month and pay four instalments.

## Getting the estimate right

If the estimate is below 90% of the actual chargeable income, URA charges 20% of the difference in tax. Unpaid tax carries interest of 2% a month.

## Who is excluded

Presumptive taxpayers do not pay provisional tax.
