My first ever self assessment, need a bit of help.

Aldi1234

Just completed my first self assessment tax return but not yet hit the 'submit' button (all because I'm now in receipt of a tiny Netherlands state pension). I think I've done ok , however when I viewed my calculation the 10% Married personal allowance from my wife's account was missing, leaving me only with the £12,570 standard personal allowance. Before self assessment I'd benefitted from the £1,260 extra allowance for the last few years. Am I dong something wrong?

You cannot have a Personal Allowance greater than £12,570.

Receipt of Marriage Allowance entitles you to a tax reduction of £252.  Which will be further down the calculation.

But HMRC have an odd system where you (the recipient) has to file the return without that showing, as you cannot "claim" Marriage Allowance, but they will issue a revised calculation once you file the return and their systems recognise your spouse had applied for that tax year.
