Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how many shipping companies that qualify for tonnage tax operate container lines from UK ports.

The information requested is not available. It is not possible to identify which shipping companies qualifying for tonnage tax operate container lines from UK ports, because companies paying tonnage tax are not required to declare this information in tax returns.

HMRC does publish the total number of companies paying tonnage tax in its publication on non-structural tax reliefs, available here: https://www.gov.uk/government/statistics/main-tax-expenditures-and-structural-reliefs. In 2018-19, in total 415 companies paid tonnage tax.
