The Singaporean government has attempted to make it easier for taxpayers to file income tax returns by introducing the e-Filing system. There are multiple reasons why taxpayers should use e-Filing instead of conventional paper forms to file tax.

File Tax by Using e-Filing

Every Singaporean taxpayer is legally obligated to file an income tax return once a year. For the sake of taxpayers’ convenience, the Singaporean government allows taxpayers in Singapore to use e-Filing to file income tax returns. There are several advantages to using e-Filing when compared to conventional methods of income tax filing.

Taxpayers who choose to use e-Filing to file tax generally find it easier to complete this task. This is because as soon as the taxpayer is done filing, the taxpayer will receive a message confirming this fact. Those who use e-Filing are also able to access their tax accounts at any time they wish to. The use of e-Filing also grants the taxpayer a longer e-Filing period. The filing due date for those who use e-Filing is three days later than the due date in use for e-Filing users.

How to use e-Filing

There are seven steps in the process of e-Filing via myTax Portal. They are as follows:

1) Obtain a SingPass or IRAS Unique Account (IUA)

A SingPass is a password that can be used to access Singaporean government e-Services. Most people who apply for a SingPass online will receive one within four working days. Those who are ineligible for a SingPass may apply for an IUA. IUAs replaced IRAS PINs on December 19, 2018.

2) Prepare Necessary Documents

The following documents are required before one logs in to myTax Portal (a Singapore government-run portal that allows taxpayers to manage and view tax transactions): a SingPass or IUA; Form IR8A (if the taxpayer’s employer is not a participant in the Auto-Inclusion Scheme); particulars of any dependants for new relief claims; details of rental income from property and other income, if any; and the Business Registration Number or Partnership Tax Reference Number (these only apply for the self-employed and partners respectively).

3) Log in to myTax Portal

Use a SingPass or IUA to log in. Once this is done, click on “Individuals”, then “File Form B/B1” to begin the process. It takes most people between 5 to 10 minutes to complete all the necessary steps.


4) Verify all pre-filled information

The Inland Revenue Authority of Singapore (IRAS) will pre-fill some of the information presented in the online tax form. This pre-filled information will include data on income, deductions, and reliefs; what reliefs you have claimed during the previous year; and tenanted property information based on your preceding year declarations or any e-Stamping records. Check with the relevant organizations if there are any inconsistencies.


5) Update Current Tax Reliefs

Any reliefs which you no longer qualify for must be removed from the pre-filled sections during e-Filing. Conversely, any reliefs for which you did not previously qualify, but now do, must now be included in those sections. You can also modify the amount of reliefs which are shared with other claimants.


6) Declare other Income Sources

Any other sources of income which are not pre-filled must be declared in the tax form.


7) Receive the Receipt of Acknowledgement

After completion of e-Filing, an acknowledgement page will be displayed. Save a copy of, or print, this page for future reference.
