IRAS myTax Portal e-services

For years, the IRAS has been encouraging individuals and companies to move their tax filings online electronically thus, standard forms such as Form C for annual corporate tax filing can now be submitted via the IRAS portal. This has the benefits of greatly reducing paper form submissions which can be cumbersome and slow.

Taxpayers can retrieve tax-related information from the portal. Corporations with appointed third-party tax professionals for handling their annual tax filing processes are also able to submit e-forms on behalf of the taxpayer where proper access is granted. Some e-services offered on the portal are individual tax filing, corporate tax filing, quarterly GST submission, property tax submission and e-stamping of contract documents.

In the case of individual taxpayers, some of the common e-services that can be completed via the portal include checking of employment income status, filing income tax returns and applying for GIRO. GIRO is an instalment plan for total annual tax payable. Businesses (companies, tax agents or income tax preparers) will mainly access the portal for submission of Estimated Chargeable Income (ECI), Form C or Form – CS every year. Companies may also use the IRAS online tax portal for GST related matters such as registration for GST, checking of GST registration number and filing for GST return. Property owners can use the online portal to check their property tax balances and for filing payment of relevant property taxes. Another popular e-service offered on the portal is the e-stamping of legal contracts such as Sale & Purchase Agreement, Tenancy Agreement or Share Transfer Mortgage.

In addition to studying various IRAS tax guides, engaging a qualified tax professional may be a good option to ease one’s tax filing procedures. Accounting experts have ample experience with navigating the IRAS tax portal to ensure individuals and companies they represent comply fully with the tax filing procedures and deadline.
