• 1

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

• 2

  Treat the computed US Dollar amount as the base figure for United States: 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.

• 3

  When comparing two options for United States, run both through this stamp duty with the same rate and the same US Dollar basis; then the difference you see reflects the options themselves rather than an inconsistency between the two inputs.

• Assessed value is not market value: United States property levies apply the official assessment or band to the rate, so typing the US Dollar 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 States Stamp Duty field expects before you type.
