The stakes
An investor's disposal gain sits outside the tax net entirely — zero, however large. A trader's identical gain is business income at resident progressive rates up to 24 percent, with deductible losses as the consolation. The distance between those outcomes is the full value of every gain you make, and the classification is not elected on a form: IRAS reads it from conduct, after the fact, under the badges of trade.
The badges, in crypto terms
The classic factors translate directly. Frequency and volume: daily rotation across pairs reads differently from a handful of purchases a year. Holding period: positions measured in hours accumulate a trading complexion; years of custody support investment. Financing: leverage and borrowed funds are a commerce signal — investors rarely pay interest to hold. Organisation: bots, subscriptions to signal services, dedicated time and infrastructure look like a business being run. Intent and circumstances: what you wrote, told platforms, and did around each purchase. No single badge decides; the picture does — and the picture is cumulative across years.
Eleven schedules on this site argue about rates. Singapore's argues about identity: the question is never how much tax the gain carries — it is whether you are the kind of person whose gains carry tax at all.
Where it blurs
DeFi puts weight on the scale. Systematic yield farming, liquidity provision run like an operation, high-frequency NFT flipping — activity can carry the badges even for someone who self-describes as a holder. Scale, repetition and organisation are what IRAS weighs, not vocabulary. The honest position: the boundary is judged case by case, there is no safe-harbour number, and anyone near the line is better served by a professional read of their actual pattern than by any article — including this one.
Arrivals: the cleanest version of the rule
Gains accrued before you became Singapore-resident are not Singapore's to tax. What matters is the ability to show the separation: a valuation snapshot of the portfolio at the move, kept with the same care as the trade log. The exemption is generous; the evidence burden is yours.
What to do
- Read your own pattern annually. Frequency, holding periods, financing, tooling — score yourself against the badges before anyone else does.
- Keep the records that prove the status. In a no-CGT system, line 14 exists for exactly this: dates, units, values, purpose — five years deep.
- Snapshot the portfolio at residency changes. Pre-arrival gains stay out of the net only if the boundary is documented.
- Near the line, get a professional classification memo. A considered position taken early beats an improvised defence taken late.
