CA81100 - Dredging: Writing down period

CAA01/S487(2)

Dredging allowances on an item of qualifying expenditure are given during a writing down period. No allowances are available for a chargeable period if that chargeable period falls outside the writing down period even if there is still some expenditure for which allowances have not been claimed.

The writing down period for qualifying expenditure is the 25 year period that begins with the chargeable period in which that qualifying expenditure was incurred.

Example

Doug incurs qualifying expenditure in his chargeable period 24 May 2011 to 23 May 2012. The writing down period for that qualifying expenditure is the 25 year period from 24 May 2011 to 23 May 2036.
