• 1

  United Kingdom publishes inheritance tax 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 inheritance tax 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

  When comparing two options for United Kingdom, run both through this inheritance tax with the same rate and the same Pound Sterling basis; then the difference you see reflects the options themselves rather than an inconsistency between the two inputs.

• Rates in United Kingdom move — annually, or with each fiscal announcement — and a Inheritance Tax result computed from last year's figure misleads budgets and quotes alike. Re-enter the current rate whenever the underlying number changes.

• 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 Inheritance Tax field expects before you type.
