Trash, it isn't. If you are on PAYE the tax is allocated to wherever your company reports from. The location of your tax office has no bearing on the matter. I have worked for companies in Watford tax office in Portsmouth; Reading, tax office in Newcastle; Bury, tax office in Bury; Manchester, tax office in Leeds whilst all the time living in the Manchester area. When I worked for a company in Croydon, reporting from a Peterborogh HQ, the tax office was Edinburgh then changed to Liverpool. The same for National Insurance. VAT take is based on the reporting HQ. The only time branches would be involved is if the VAT man linked a query to a branch.
