• 1

  Singapore publishes stamp duty figures in Singapore Dollar, revised periodically — enter the rate currently in force for your case in Singapore rather than an older stored figure so the result matches the official calculation.

• 2

  Keep the stamp duty amount and rate for Singapore on one period and one basis — monthly Singapore Dollar figures with an annual rate, or gross with net, give a number that is arithmetically right but misleading in practice.

• 3

  Treat the computed Singapore Dollar amount as the base figure for Singapore: any additional local fees, deductions, or rounding rules that apply to your situation must be added separately, so the number you rely on stays honest and complete.

• A percentage entered as a whole number where a decimal is expected (15 versus 0.15) is off by ×100 — the most common single error in rate fields. Check which form the Singapore Stamp Duty field expects before you type.

• Assessed value is not market value: Singapore property levies apply the official assessment or band to the rate, so typing the Singapore Dollar purchase price alone can misstate the bill. Use the assessment on the official notice as the base.
