Singapore
Taxable period
The tax year in Singapore is the calendar year.
Singapore tax filing deadline 2024
An individual’s income from a preceding calendar year is assessed to tax in the following calendar year (i.e. year of assessment).
Tax returns
Each taxpayer is required to make an annual return of income and of such particulars as may be required to determine the personal reliefs and deductions.
The tax return must be filed on a calendar-year basis and must be submitted by 15 April. If filed electronically, the deadline is 18 April.
Payment of tax
The tax assessed is payable within one month of the date of the assessment whether or not a notice of objection to the assessment has been lodged with the tax authorities.
The notice of objection must be lodged within 30 days of the date of the notice of assessment, failing which the assessment will be treated as final.
In the case of an employee, the tax authorities will, upon application, generally allow the payment of tax by monthly instalments with no interest, using the Interbank GIRO system (an interbank fund transfer system).
