That just shows that you live in the past tuerto
The inland revenue ceased to be several years ago. It is now Her Majesty's Revenue and Customs.
you can work out when because it is the same point at which your communication with the Tax Office started to go tits-up.
As an example despite phone calls in double figures I am still trying to resolve as problem that I first asked them to address in April last year, and have yet to receive one written communication about. Their excuse (And it is fast becoming an excuse for everything being late bad or not at all) has consistently been, "We are too busy with covid and we furloughed all our staff"
They amalgamated the IR and the Customs Service but neither one would talk to the other or share information and it all went to rat shit. I think it's called progress.
Oddly enough previously the people who collected our income tax worked for the Inland Revenue and the customs who collected VAT and tried to stop smuggling were historically known as 'Revenue men'
So I get no satisfaction form then and neither will you if you ask to speak to the 'inland revenue'
