Before you make a payment, you need to tell HMRC about overclaimed Research and Development (R&D) tax relief.

We will send you a payment reference number that you can use to make a payment.

When to pay

We suggest you make a payment on account for the amount in your offer within 30 calendar days of submitting your disclosure. Doing so will prevent any further interest accruing.

If day 30 is on a weekend or bank holiday, make sure your payment reaches HMRC by the end of the previous working day.

What you need

You need your 15-character payment reference number, starting with X, when you pay.

You can find this on the letter HMRC sent you after you submitted the disclosure.

If you use the wrong reference number:

• your payment may be delayed
• your payment may be used to pay a different tax bill that you owe
• you will receive a payment reminder

If your payment has paid the wrong tax bill, you can contact Corporation Tax general enquiries to ask for your payment to be moved.

Pay now

Paying online through your bank account

You can pay by approving a payment through your online bank account by selecting the ‘pay by bank account’ option.

You will be directed to sign in to your online or mobile banking account to approve your payment.

You will need to have your online banking details to hand to pay this way.

Paying online by Direct Debit

Set up a Direct Debit through your HMRC online account.

You’ll need the sign in details you used when you registered for the account. If you do not already have sign in details, you’ll be able to create them.

You must pay in a different way if you are making a payment of more than £20 million.

You should set up the Direct Debit at least 5 working days before the date you want your payment to be collected.

You can only use this service if you have registered for one or more of the following services:

Paying by debit or corporate credit card

You can make a full payment online using a debit or corporate credit card. There is a non-refundable fee if you pay using either of these methods. You cannot pay by personal credit card.

Your payment will be accepted on the date you make it and not the date it reaches HMRC’s account (including weekends and bank holidays).

You must make sure the details you enter match those held by your bank or card provider. For example, the billing address should match the one your card is currently registered with.

Pay by bank transfer

If you pay by CHAPS (Clearing House Automated Payment System) or Faster Payments, you can submit your payment on the same or next day.

If you pay by Bacs (Bankers Automated Clearing System), allow 3 working days for the payment to reach HMRC.

We recommend you check your bank’s processing times and maximum transaction limits before you pay.

Use the following details to make a payment if your account is in the UK:

• account name — HMRC Shipley

Account details to use if your account is overseas

• account number (IBAN) — GB03 BARC 2011 4783 9776 92

After you’ve paid

We will write to you to let you know if we have accepted your disclosure. The letter you received with your payment reference number on will have more information on the amount of time this may take.

If we do not accept your disclosure, HMRC will contact you to let you know the next steps.

If you cannot pay the full amount

Contact HMRC if you cannot pay the full amount you owe as soon as you get your payment reference number. The payment reference number and HMRC contact details can be found in your letter.
