Might be a dumb question, but just want to be clear in my head.
I've done my self assessment and I owe £1k. I can either pay it off or adjust my tax code for 2023/24
If I did the latter, they will lower my tax allowance so I pay them more back.
But then, in essence, as my tax allowance is lower, I'll hit high rate tax sooner and pay more @ 40%
Or am I wrong, it will just all work itself out and be fine?

I've been saying this from day dot!! I couldn't be bothered to work out all the numbers but with only being 5k into the higher tax band but I'm sure it'd be better upping the pension, saving on tax there, keeping the child benefit etc. Might end up around £1k physically out of pocket over the year but gain much more come pension time (granted there's the unknown with stock market etc ref pension and whether you make it to the age to draw on it).
