Can I pay HMRC ahead of receiving a tax demand?

I've only just sent my 2022/23 paper tax return to HMRC but have no idea how long it might take to process and issue my tax liability demand. Is there any way I can pay HMRC an amount now that I think will cover my tax liability such that I minimize any late payment fines I will have, and already have, incurred?

Hi ahasuerus24,
Yes you can make a payment to your account which would minimize late payment penalties and interest charges Pay your Self Assessment tax bill.
Thank you.
