Corporation Tax Act 2009 Explanatory Notes

Section 184: Cases where adjustment not required until assets realised or written off

697.This section is a timing rule for an adjustment which results from any of the amounts in subsection (2). It is based on paragraph 7 of Schedule 22 to FA 2002. The corresponding rule for income tax is in section 235 of ITTOIA.

698.The amounts in subsection (2) are:

  • closing trading stock;

  • opening trading stock; and

  • depreciation.

699.The general timing rule is that any adjustment is made at the start of the first period of account on the new basis (see section 181(2) and (3)). But any adjustment for stock or depreciation is made when the asset is realised or written off.
