• 1

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

• 2

  A stamp duty result for United Kingdom is only as current as the rate you typed in: when the figure matters, re-run it with a freshly confirmed Pound Sterling rate instead of one saved last month.

• 3

  Treat the computed Pound Sterling amount as the base figure for United Kingdom: 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.

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

• 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 United Kingdom Stamp Duty field expects before you type.
