Payment gone from bank account not showing up on my HMRC page as paid

Money left my online bank account on the 30th January, but it does not show up as paid on my self- assessment account page. I f it still doesn't show as paid by the end of the day will I get fined? If so, can I appeal based on the online evidence that it went from my bank account to HMRC on the 30th of January?

Hi,

You need to allow 5 working days for it to show. The payment date will be the 30th, as this is the date you made the payment.

Thank you.
