How to pay a non self assessment retrospective tax bill for 2020/21

areader

In my personal online HRMC account I received the message below on the 1st February this year stating that I owe some tax for the year 2020/21. I accept that I owe this money (for untaxed interest) but cannot figure out how to pay it. If at all relevant, I did not fill in a self assessment form for this tax year.

I have been waiting for a further message or letter through the post since it says "We will contact you soon to tell you ways you can pay what you owe" but it has now been over 2 months and I've heard nothing.

I have also received a "Simple Assessment tax calculation for the year 6 April 2019 to 5 April 2020" which had a Charge Reference of format XN00123456789 and was able to pay that here.

In summary, what is the simplest, quickest and most reliable way I can pay this bill? Online preferably, without needing to send a cheque and explaining covering letter through the post. It does not appear to be a Simple Assessment tax bill and there is no payment reference.

MR FIRSTNAME SURNAME

You have paid too little tax.

You owe HMRC £212.50

What happens next

We will contact you soon to tell you ways you can pay what you owe. If you have already made a voluntary payment, you will only need to pay the balance owed.

Why you have paid too little tax

Each year we check to see if the correct amount of Income Tax has been paid. We have now looked at the latest information we hold for this year and have worked out that you have paid too little tax. You can find a full calculation and explanation in this letter.

Now check this calculation

You must tell us if you think the information we hold is wrong or about any changes to your taxable income. Find out more about tax overpayments and underpayments on GOV.UK.

can't you just sign-in and pay?

errr, possibly! I could be massively overthinking this. Do you have a link to where I can make ad-hoc personal tax payments? I can't find anything particularly obvious or relevant.

This bit appears very relevant.

It looks like online payment of a Simple Assessment bill that old (in tax year terms) isn't possible.

If you owe tax from before 6 April 2022 you cannot see and pay tax using your Personal Tax Account.
