What's mildly irritating you today?

[Carruthers]

On Monday an instantly recognisable letter (UK Dwellars will shudder) from HMRC landed on the mat, the latest in a saga. (Post #6604 et seq)

A few months ago my tax code was adjusted so that more tax was taken because I hadn't paid enough during FY 2018-19.

That's supposedly an arithmetical fact and not a debating point according to the taxman.

On Monday of this week I received another letter saying that I had paid too much tax for FY2018-19 and a refund would be made.

Today (Thursday) I've received yet another missive altering my tax code to take less tax for the current FY, at least I think that's what it says.

They always include a killer clause which says if the calculation is correct you don't need to do anything, but if it's wrong and I don't say anything because I don't know it's wrong, I suppose that could be held against me in the future.

Will it never end?
