3. Deadlines for Filing Personal Tax Returns

Where a personal income tax liability is paid in 3 instalments, each instalment must be made by the following deadlines:

• First instalment – must be paid when filing the personal income tax return by the extended deadline;
• Second instalment – must be paid within one month of the day that the first instalment was paid; and
• Third instalment – must be paid within one month of the day that the second instalment was paid.

If any instalment is not paid by the specified time, the taxpayer loses the right to continue paying taxes in instalments, and must pay a surcharge for any unpaid and subsequent instalments. The surcharge shall be calculated from the date that the extended deadline ends until the date that payment is made.
