How to e-File

From 1 Sep 2018, CorpPass will be the only login method for online corporate transactions with the Government. All payers (except for individuals) must first set up the authorisation in CorpPass for its users before they can log in to IRAS digital services. For assistance on CorpPass set-up, please refer to the Step-by-Step guide on how to register for CorpPass.

For foreign individuals (who are ineligible for SingPass), the IRAS Unique Account has replaced IRAS PIN. To e-file WHT, you need to register and activate the IRAS Unique Account first.

This step is required if your company is e-Filing WHT for the first time or when there is a change in the persons filing the WHT.

For Company Staff/Third Party

The person e-filing the WHT has to be assigned with the S45 Withholding Tax (Filing) and/or S45 Withholding Tax (GIRO Deduction Details) e-Services in CorpPass by the CorpPass Administrator (CPA)/Sub-Admin of the company. However, the CPA/Sub-Admin does not need to assign the S45 Withholding Tax (GIRO Deduction Details) e-Service if the user is not required to view the GIRO deduction details. 

However, if the WHT is e-filed by a third party (e.g. tax agent), the third party must be authorised in CorpPass to act for the company.  

All users who are e-filing WHT for a non-Singapore registered company (e.g. REITS) or foreign company must also be assigned with the “For Non-UEN Only” e-Service.

Assignment of 'Preparer' and 'Approver' Role

When assigning the S45 Withholding Tax (Filing) e-Service to a user in CorpPass, the CPA/Sub-Admin will be required to select the user’s role as either the ‘Preparer’ or ‘Approver’.

Do note that any users who are authorised with “access to all e-Services” in CorpPass will be assigned with the Approver role by default.

For Sole-Proprietor (Only applicable to Local/Foreign Individuals)

Sole-proprietors (SPs) are required to log in to myTax Portal using their SingPass or IRAS Unique Account to e-file the WHT to IRAS. Do note that you are not able to authorise staff or third party to e-file the WHT on your behalf. 

Once you are authorized for WHT e-filing, use CorpPass to log in to myTaxPortal for "Business Tax Matters or Client Tax Matters", whichever is applicable, to e-file for the company.

Once you are authorised, you can log in to myTax Portal to complete and e-file the withholding tax. However, before e-filing, there are points to take note: -

• There are 2 ways of e-filing submission - S45 Online e-Filing (2.109MB) or submit a single file via S45 Offline Data-Entry (ODE) application (1.942MB) 
• If your company is filing WHT for services rendered by a non-resident company, please select the Nature of Payment ‘Technical Assistance Fee’. For services rendered by an independent contractor (i.e Non-resident professional), the Nature of payment is ‘Payment to Non-Resident Individual/Firm Exercising Profession/Vocation in Singapore’.  
• Date of Payment
  This refers to the Date of Payment to the Non-Resident. To ensure the declaration on date of payment is correct, please refer to the information on determining the date of payment in When to File and Pay Withholding Tax to IRAS 
• Period of Payment
  This refers to the period of interest, technical assistance rendered, director’s fees etc for which the payment is made for. If the Period of Payment covers more than 1 year, you will be prompted to file for each calendar year separately.
• Period of Engagement
  This refers to the period in which the non-resident professional or non-resident public entertainer is engaged to render their services. If the Period of Engagement covers more than 1 year, you will be prompted to file for each calendar year separately.
• Taxable Income
  This refers to the gross amount that is subject to WHT.
  
  All figures reported in the WHT Form must be in Singapore Currency. However, if your payment to non-resident is in foreign currency, you may use your bank's foreign currency selling rate or the daily exchange rate provided in the MAS' website based on the date of payment to the non-resident to convert into Singapore dollar. 
  
  Drop the cents when declaring the gross taxable income.
• Relief/Incentive (if applicable)
  Please select the applicable relief/incentive under the Relief/Incentive (if applicable) if your company is applying Double Tax Relief or Approved Royalty Incentive rate on the withholding tax records to be e-filed.
• Only users who are authorised as Approver can submit the e-Filing to IRAS
• You should receive an acknowledgment page upon successful transmission of the e-Filing. 

Save and read the instructions in the acknowledgment page to make payment (if applicable) to IRAS by the due date.
