Tax treaties and non-resident professional

Key requirements

Use IRAS’s current-engagement DTA calculator and the treaty text. Where exemption applies, the professional completes and signs IR586 and gives it to the payer, who claims the exemption in the withholding filing. The form is retained rather than routinely submitted, unless IRAS requests it. For multiple visits under a contract, the page directs the claim after completion when total physical presence is known. Prior-year situations should follow the instructed enquiry route. If no treaty exemption applies, the payer must file and remit withholding by the ordinary deadline.
