Crypto exchanges operating in Singapore will have to collect customer tax residency information and report transaction details to the Inland Revenue Authority of Singapore from 2027 under the Crypto-Asset Reporting Framework, an OECD-developed system for exchanging crypto tax data between jurisdictions.

Firms must register with IRAS by 31 March 2028 and obtain self-certification from existing customers by the end of 2027 to determine their tax residency. They will report annual transaction data including the value and number of crypto purchases, sales, trades and transfers for reportable users, as well as crypto payments for goods and services worth more than US$50,000. First reports covering the 2027 calendar year are due by 31 May 2028, with IRAS then sharing the information with tax authorities in jurisdictions where users are tax resident.
