Unpaid Tax - Which exchange rates would they use?

julians_2

If someone had unpaid tax from say 1999-2000 and the money was held in dollars - would the tax people use today's exchange rate or some average from that period?

Thanks for any thoughts,

You owe tax but need to pay in US dollars? It would be at today's exchange rate. If you had income from 1999-2000 in US dollars and need to convert to sterling in order to declare to HMRC, you would use an average from that period.
