I hate these!
Every year I fill it in and return it because I mad a rather large claim when I paid some student fees for a self funded course. I only have one income and no pension
I then get a letter saying that I owe them lots of tax, I then question t his and they send me a second letter with greatly reduced amount or in 3 of the last 5 years they have on re-assessment owed me money.
Then I get the D0 tax code (40% on all earnings with no allowances
I then phone and query this when they state that I have a second job in Cardiff and that is why I he been taxed thus
I then point out that apart from cycling through once I have never been to Cardiff.
They then admit this is also a mistake and revert me to a normal tax code
The first year it was probably a mistake, but to repeat the same mistakes for three consecutive years is riddiculous.
