Physical payments

There are various methods available to pay tax that is due. You can post a cheque to HMRC for the full amount of thetaxbill, or by giving your local bank branch a pay-in-slip provided bt HMRC. Digital payment methods are also availableandwidely utilised online.

Digital payments

Paying tax using a bank transfer, direct debit or debit card is the quickest and most accessible method. The ClearingHouse Automated Payment System (CHAPS) is accessible through HMRC’s self-assessment online portal. It is worthnotingthat credit cards are no longer accepted.

Advance payments

Depending on the amount of the tax bill, some people will opt to pay the tax owed through a budget payment plan. Thiscan be set up online, be paid weekly or monthly, and works as an advance payment towards the next tax bill.Depending onthe amount you choose to pay, and how often, the accumulated sum will be deducted once the self-assessment form forthenext tax year. If you overpay via the budget payment plan, you will be eligible for a refund. This option may beespecially helpful for the self-employed, as spreading out the cost instead of paying as a lump sum limits thefinancialimpact, one which could jeopardise your ability to remain in self-employment.

Payments on account

Payments on account’ are advance payments towards your tax bill (including Class 4 National Insurance if you’reself-employed).

You have to make 2 payments on account every year unless:

• your last Self Assessment tax bill was less than £1,000
• you paid more than 80% of the previous year’s tax you owed, for example through your tax code or because yourbank hadalready deducted interest on your savings

Each payment is half your previous year’s tax bill. Payments are usually due by midnight on 31 January and 31July.

If you still have tax to pay after you’ve made your payments on account, you must make a ‘balancing payment’ bymidnighton 31 January next year.

If you know your tax bill is going to be lower than last year, you can ask HMRC to reduce your payments onaccount. Youcan do this either online or by post.

Late payments

If you fail to pay your tax bill before the tax year deadline, a fine of £100 will be issued immediately. You willthenalso be liable to pay interest on your tax bill. Further fines and higher interest will be applied if you continuetopay income tax, national insurance, or do not submit your self-assessment. HMRC can charge penalties of up to 100%ofyour tax bill, and they will suspect you of attempting to hide untaxed income, even if the mistake was benign.
