The tenant under a taxed lease is treated as incurring an expense of a revenue nature in respect of the premises subject to the taxed lease for each qualifying day.

If there is more than one taxed receipt, this section applies separately in relation to each of them.

A day is a “qualifying day”, in relation to a taxed receipt, if it falls within the receipt period of the taxed receipt.

The amount of the expense for the qualifying day by reference to the taxed receipt is given by the formula—

$\frac{A}{\mathrm{TRP}}$

where—

A is the unreduced amount of the taxed receipt, and

TRP is the number of days in the receipt period of the taxed receipt.

No expense is to be determined under this section by reference to the taxed receipt if subsection (4B) or (4C) applies.

This subsection applies if there would have been no taxed receipt but for the application of Rule 1 in section 303 in determining the effective duration of the lease.

This subsection applies if there would have been no taxed receipt but for the application of Rule 1 in section 243 of CTA 2009 in determining the effective duration of the lease for the purposes of Chapter 4 of Part 4 of that Act.

This section is subject to sections 293 and 294 (restrictions on expenses where the additional calculation rule is relevant).

For the meaning of expressions used in this section, see in particular—

• section 288(6) (“receipt period”), and

• section 290(2) to (4) (“unreduced amount”).
