Collection of self assessment tax through PAYE tax code

If I am able to submit a self assessment return before the end of December I can opt to have any tax collected via my PAYE tax code (subject to criteria), however, on this years calculation it has triggered payments on account due what happens with these when the tax is being collected via the tax code rather than a lump sum being paid at the normal times? Also if still able to do via tax code and if the payments on account are then not applicable do I have to adjust these in some way on my tax return? Any help would be most appreciated.

Is anyone from HMRC admin able to help on my query?

Hi Zorba,
If you meet the criteria to have the 2023/24 balance collected in your tax code then once updated to collect the balance the payments on account set up for 2024/25 will automatically be reduced to nil. 
Thank you. 

Hi thank you for your reply, so if collected through my tax code then does it basically mean I don’t have to pay any payments on account towards the next year even though they are showing as triggered due to being above relevant amount? I tried speaking to hmrc by phone and the gentleman I spoke with told me i could have the balance collected through my tax code but that I would still need to pay the payments on account as normal as they are mandatory. Bit confusing.

Hi,
No - you will still need to pay your Payments on Account, these cannot be coded.
Payments on Account are predictions of the tax that you will owe for the tax year that is ongoing or just finished, and should ideally be paid from money you have set aside to pay for that year's tax. 
Thank you.
