The easiest and fastest way to pay your self assessment tax is using the HMRC online payment portal. All you will need is:
- The value that you need to pay – This should have been given to you when you signed off your tax return;
- Your debit/credit card – There is a small fee for using credit cards;
- Your UTR – This can be found on all HMRC correspondence concerning your personal tax affairs or on your tax return.
If you can’t find any of this information or your unsure of anything then contact your accountant and they should be able to provide you with everything you need to pay your self assessment tax.
