Singapore Income tax (international tax compliance agreements) (crypto‑asset reporting framework) regulations 2026

1️⃣ From 1 Jan 2027, exchanges must report your trading data to IRAS

Any crypto exchange, broker, or trading platform with a Singapore nexus (incorporated, managed, or operating here) must report annual aggregates per user, per token: fiat buys/sells, crypto-to-crypto swaps, transfers in/out. IRAS then auto-exchanges this with tax authorities in your country of tax residence

2️⃣ Mandatory KYC self-certification - no cert, no trading

New users must declare tax residency, TIN, and DOB at onboarding from Day 1. Existing users have until 31 Dec 2027 to submit. From 1 Jan 2028, exchanges are legally barred from executing trades for anyone without a valid self-certification.

3️⃣ Crypto is now baked into the traditional banking rules too

Crypto-assets are now "financial assets," entities managing crypto for clients count as investment entities, and e-money/CBDC accounts become reportable depository accounts. So even if you hold crypto through funds, custodians, or wealth platforms rather than a CEX, the reporting requirement is still there

4️⃣ This is for transparency sake, not new tax

Nothing here changes Singapore's tax treatment - no capital gains tax for individual investors. But the era of CEX activity being invisible to tax authorities formally ends in 2027
