Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how many claimants of decommissioning tax relief from corporation tax there were in each financial year between 2013-14 and 2022-23.

Estimates of the cost of tax reliefs used by oil and gas companies under the Ring Fence Corporation Tax (RFCT) and Petroleum Revenue Tax (PRT) regimes, including the costs of RFCT and PRT decommissioning tax reliefs, are published at tax relief statistics gov.uk (www.gov.uk). This publication contains non-disclosive estimates of number of claimants for each relief, where relevant data are available.

A succinct summary of the UK’s ring fence oil and gas tax regime, including the relief available for decommissioning-related losses, is available on the relevant EITI website.
