Paying tax bill through next year tax code

For 22/23 tax year I have a tax bill (under £3000 and meets the other rules) My account shows I owe for Tax year ending 05 Apr 2023, a balancing payment with a due date of 31 Jan 2024 Below it says "How to Pay" linking to https://www.gov.uk/pay-self-assessment-tax-bill/through-your-tax-code This pages makes no mention of how HMRC confirm this will happen Will HMRC update my 24/25 tax code to collect this bill ? How will I know they will do this? If the payment is due 31 Jan 2024 surely I need confirmation that HMRC will collect via my tax code before this date to avoid any penalty

Hi
If you requested it to be collected through the code when you completed the return it should have already been updated to indicate this.
If you wish to check you will need to contact our Self Assessment department.
