Singapore Withholding Tax Filing Guide
Here's a breakdown of the key aspects on Withholding Tax (WHT) filing with the Inland Revenue Authority of Singapore (IRAS):
What is Withholding Tax (WHT)?
Withholding tax is a requirement for individuals or companies (payers) making certain types of payments to non-resident individuals or companies (payees). The payer must deduct a percentage of the payment and remit this withheld amount to IRAS. This ensures that non-residents pay tax on income sourced from Singapore, similar to how residents pay income or corporate tax.
Types of Payments Subject to WHT and Rates:
The WHT rates vary depending on the nature of the income. Here are some common examples:
Interest, commissions, fees related to loans: 15% (final tax if operations are outside Singapore; otherwise, prevailing Corporate Income Tax rate for non-individuals, 24% for individuals).
Royalties for movable properties: 10% (final tax if operations are outside Singapore; otherwise, prevailing Corporate Income Tax rate for non-individuals, 24% for individuals).
Payments for use of scientific, technical, industrial, or commercial knowledge: 10% (final tax if operations are outside Singapore; otherwise, prevailing Corporate Income Tax rate for non-individuals, 24% for individuals).
Rent for movable properties: 15% (final tax if operations are outside Singapore; otherwise, prevailing Corporate Income Tax rate for non-individuals, 24% for individuals).
Technical assistance and service fees, management fees: Prevailing Corporate Income Tax rate (not a final tax for companies, allowing expense claims). For non-resident individuals, the rate is 24% (22% for income due/payable from 01 Jan 2016 to 31 Dec 2022).
Proceeds from the sale of real property by a non-resident property trader: 15%.
Distribution of taxable income by a Real Estate Investment Trust (REIT) to a non-resident non-individual: 10% (for distributions from 18 Feb 2005 to 31 Dec 2030).
Payment to non-resident director: 24% (22% from 01 Jan 2016 to 31 Dec 2022).
Payment to non-resident professional: 15% on gross income or prevailing non-resident individual rate (currently 24%) on net income.
Payment to non-resident public entertainer: 15% on gross income (10% for income due/payable from 22 Feb 2010 to 31 Mar 2020).
Filing and Payment Due Date:
You must file and pay the WHT to IRAS by the 15th of the second month from the date of payment to the non-resident.
For example, if you made a payment on 19 May 2024, the filing and payment due date would be 15 July 2024.
If you are on GIRO for WHT payment, the deduction occurs on the 25th of the month the tax is due. If the 25th falls on a weekend or public holiday, the deduction will be on the next working day.
How to File:
You need to e-file your WHT return via the S45 e-Services on the myTax Portal using your Singpass.
There are two ways to file:
S45 Online Filing: For filing a few records.
S45 Offline Data-Entry (ODE): For filing many records using an Excel-based template.
Steps to File:
Authorize Users: If you are filing on behalf of an organization, you need to authorize staff or tax agents via Corppass.
File on mytax.iras.gov.sg: Log in and select the relevant S45 e-Service.
View Acknowledgement and Pay: Follow the instructions to complete the form, view the acknowledgement page, and make payment.
View S45 Notices and Letters: You can view and download related documents on the portal.
Payment Methods:
GIRO: Preferred method. You can apply for eGIRO online.
Electronic Payment Modes: Internet Banking, DBS PayLah! Mobile App, Phone Banking, ATM, AXS Station/Online Platform, SAM Kiosk/Online Platform, Internet Banking Fund Transfer.
Important Considerations:
Date of Payment: This is crucial for determining the filing and payment due date. For service fees, it's often based on the invoice date. For director's fees, it depends on when they are approved.
Consolidated Filing: You can consolidate multiple payments to the same non-resident for the same engagement within a 60-day period into one filing, using the last payment date. For tax-exempted payments under Double Taxation Agreements (DTAs) or the Approved Royalties Incentive (ARI), you can consolidate filings twice a year (by 15 June and 15 December).
Avoidance of Double Taxation Agreement (DTA): If the payment is exempt under a DTA, you still need to file the WHT return. You may need to claim relief under the DTA.
Late Payment Penalties: Penalties will be imposed for late payment.
Amendments: You can amend WHT records submitted within the last two years online via the portal. For older records, you may need to follow a different procedure.
It's always a good idea to refer to the official IRAS website for the most up-to-date information, guides, and FAQs related to WHT filing.
