Stamp Duty Land Tax Manual

Calculation of Stamp Duty Land Tax (SDLT): Rent: Variable or uncertain rent: Royalty payments, extraction of mineral rights etc.

Royalty payments represent payments for the use of or right over land and are treated in the same way as rent.

Since the amount payable is likely to be unascertained at the effective date and also to be variable, the provisions of FA03/S51(1) and FA03/S51(2) apply by virtue of FA03/SCH17A/PARA7, that is, a reasonable estimate of the amount payable should be included for the first five years in calculating the net present value.

Refer to SDLTM13155 for the approach when the end of the fifth year is reached.
