The character test
Singapore's income tax reaches receipts with income character: payment for work, returns on lending, rewards from an activity carried on. Salary settled in tokens is salary — taxed at market value on receipt, exactly as dollars would be. Fees for services invoiced in USDC are fees. Systematic mining run with equipment, financing and profit intent is a business whose coins are revenue. The asset never launders the character: what determines tax is what the tokens paid for, not what they are.
Staking and lending: the judged line
Rewards from staking and lending are taxable when they are income in nature — recorded at value on the day received. Where hobby-level passive delegation ends and income-generating activity begins is a judgement, not a formula: scale, regularity and organisation weigh in, the same instincts as the badges of trade. The two-step matters: for an investor, receipt can be taxable while the later disposal gain stays exempt; for someone classified as trading, both steps are taxable. Either way, the receipt log — date, units, value — is the document everything else depends on.
Vienna prices staking at zero and waits; Berlin taxes the receipt and starts a clock; Singapore asks a quieter question — was this income? — and taxes nothing or everything depending on the answer.
What generally stays outside
Airdrops and hard-fork coins that arrive without anything given in return are treated as windfalls, not income — the token that lands unrequested is not payment for anything. The moment there is a service behind it — promotion, referrals, tasks — the same airdrop becomes fees. GST adds a parallel kindness: exchanging and using digital payment tokens has been GST-exempt since 2020, though platform service fees can still carry it. And there is no wealth tax and no holdings declaration: Singapore never asks what you hold, only what you earned.
What to do
- Log every receipt with its SGD value. Date, units, market value, source — the dataset IRAS expects, and the basis for any later question.
- Sort receipts by what they paid for. Work, yield, windfall: the label at arrival decides the tax, and re-deriving it years later is the expensive path.
- Watch scale on staking and DeFi. Passive and incidental reads one way; systematic and financed reads another — and the reading is cumulative.
- Declare income-nature receipts in the YA return. The exemption covers gains, not income — mixing the two is the classic Singapore error.
