Rental (Lease) Stamp Duty in Singapore: 5 Mistakes to Avoid
Calculates stamp duty on a tenancy agreement of four years or less at 0.4% of the total rent. The maths is not complicated, but a handful of errors come up again and again in this and related tax & gst calculations. Here is what to watch for.
IRAS issues a notice of assessment, usually from April onwards, and tax is due within a month, although most people opt for interest-free GIRO instalments. Estimating your bill early means you can budget for it instead of being surprised.
Reliefs lower chargeable income before rates apply. Common ones include earned income relief, CPF relief for employee contributions, parent and handicapped parent relief, working mother's child relief, NSman relief, course fees relief, and relief for SRS contributions and CPF cash top-ups. Total personal reliefs are capped at S$80,000 a year.
1. Adding GST to a GST-inclusive price
Retail prices shown to consumers already include GST. To find the GST inside, multiply by 9/109, not 9%.
2. Using last year's rates
Rates and rebates change in the Budget, so check the year of assessment.
3. Forgetting reliefs
Earned income relief, CPF relief and other reliefs reduce chargeable income before the rates apply.
4. Applying the top rate to all income
Singapore tax is progressive: each band is taxed at its own rate, so your effective rate is well below your marginal rate.
5. Assuming non-residents pay resident rates
Non-resident employment income is taxed at the higher of 15% or resident rates, without reliefs.
The correct method
Stamp duty = 0.4% × total rent for the lease period. Leases with total rent of S$1,000 or less are remitted.
For example, with these inputs:
- Monthly rent (S$): 3,500
- Lease period (months, up to 48): 24
the calculator returns:
- Total rent for the lease: S$84,000.00
- Stamp duty payable: S$336.00
Leases longer than four years use a different rate. Check IRAS for the latest rules before stamping.
