Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what the most recent estimate is of the cost of tax incentives and tax relief currently available to UK-based multinational companies.

An answer could only be produced at disproportionate cost.

HM Revenue and Customs (HMRC) publishes estimates of the cost of individual tax incentives and tax reliefs.

Main tax incentives and structural reliefs can be found at https://www.gov.uk/government/statistics/main-tax-expenditures-and-structural-reliefs.

Minor tax incentives and structural reliefs can be found at https://www.gov.uk/government/statistics/minor-tax-expenditures-and-structural-reliefs.

These include tax incentives and reliefs which will be claimed by UK-based multinational companies, as well as domestic firms and groups based outside the UK.

There are also some allowances and reliefs which HMRC does not have sufficient data to estimate the cost of. They can be found at this address: https://www.gov.uk/government/statistics/tax-allowances-and-reliefs-in-force-cost-not-known
