Self Assessment for >£10k interest

I'm doing this for the first time and I've got to the page that caused the self assessment: UK Interest. It has two boxes:
'Taxed UK interest. Enter net amount after tax has been taken off: (optional)'
and
'Untaxed UK interest (amounts which have not been taxed). Enter total amount: (optional)'
I assume it's the second one, as it wasn't taxed by the bank, but my Tax Code has been changing because of untaxed interest, so I was taxed through PAYE.
I still don't really understand why I'm having to do this at all, as they know how much I have, they have taxed me through PAYE, and now it's saying it's optional!
I've added up my interest from 6th Apr 23 to 5th Apr 24 and put it in the 2nd box. Does that sound right, or do I need to subtract the £1000 interest that doesn't get taxed?

Sounds right. You don't subtract allowances (just like you don't subtract personal allowance from employment income etc). The boxes that say "optional" doesn't mean it's optional to declare the interest, it just means you can leave blank if it doesn't apply. For instance you can leave the taxed interest box blank (I'm not sure why that box is still there as I thought no banks took tax off interest but there might be some accounts/financial instruments to which this would still apply).

Add up the interest and put the amount in the UNTAXED box.
The tax you paid due to your amended tax code via PAYE will be on your P60, use that figure in the appropriate box.
Your allowance will be automatically included on the calculation page depending on your marginal tax rate.
It'll all be taken account in the calculation.1 -

Thanks everyone.
I think I've done it. I was surprised to see I own the tax year I just did as well as a guess for the first half of the current one. I didn't realise you pay twice a year, either.
I haven't submitted yet. It's a bit scary when it mentions fines, etc. if you do it wrong. I'm trying my best!

I'm trying my best!They are assuming you get the same amount of interest / income next year as well.So want so cash upfront.I made sure not to go over £18,5770 in total.That way I pay no tax, as the rest is in a few ISA'S.1 -

After the tax year there is a process to check income and tax paid, resulting in a P800 (PAYE) or PA302 (Simple Assessment). These are based on Real Time Information returns from payrolls, pension payrolls, banks and building societies. So for taxpayers moved onto Simple Assessment there is no need to supply that information through Self Assessment anymore, but you should check against your records.
The final calculation process, or Self Assessment for those still submitting returns, may result in a final adjustment.

Why would it take until November to identify the exact amount of interest credited to your accounts in the previous tax year?0
