If you are paying your individual income tax by GIRO, a PIP will be arranged for you in March each year. The PIP amount is usually based on your tax assessment for the previous year. The plan starts in May and ends in Apr of the following year, thereby allowing you the maximum number of 12 monthly instalments. The plan will be revised according to your new tax assessment for the year and enclosed with your Notice of Assessment.
If you wish to revise your PIP amount any time before your tax assessment is finalised, please notify IRAS via this email service.
