How to correct VAT errors and make adjustments or claims (VAT Notice 700/45)
How to amend your VAT records if you've made errors, correct errors on your VAT Return and claim a refund if you’ve wrongly accounted for VAT.
1. Overview
1.1 What this notice is about
This notice explains how to:
- amend your VAT records if you discover they contain errors
- correct errors you discover on VAT Returns you’ve already sent to us
- claim a refund if you’ve overpaid VAT, or not claimed enough credit on a return
- claim a refund of VAT if you disagree with our decision on the VAT treatment of a supply
- claim a refund of VAT if our practices in relation to VAT are being challenged in the court
1.2 How we can help you to get your VAT Returns right the first time
Errors on your VAT Return can prove costly to you and us. If you do not correct errors, you could be liable to a penalty and interest.
2. Errors found in records
2.1 If you find errors in your VAT records
If you find errors in your VAT records, you’ll need to correct them. Read section 2.2 for an explanation on how to correct errors.
If you’ve made an error on a VAT Return you’ve already sent to us, read section 4 to find out how to correct the error.
If you deliberately fail to correct an under-declaration of VAT, you may be liable to a penalty or even criminal prosecution.
2.2 If you record or work out your VAT incorrectly
If you find an error in your business records before submitting your VAT Return, you can correct this by amending your records.
Keep a clear note to show the reason for the error and include the correct figure in your VAT account for the same period. The correct figure will then work its way through to your VAT Return.
If you’ve already submitted your VAT Return, you should follow the correction process in section 4.
3. Errors on invoices
3.1 If the wrong amount of VAT was shown on an invoice
This section does not apply if there’s been a change in the consideration for the supply. For example, if the price has changed and consequently the amount of VAT has also changed. You can find more information in section 18 of VAT Notice 700.
If the wrong amount of VAT was shown on an invoice, this section explains how you can correct it.
For example, if you’ve:
- made a mistake in working out the tax value or the VAT element of the supply
- charged VAT on a supply, but no VAT was due
3.2 Invoices you’ve issued
If the amount of VAT on a VAT invoice you have issued is:
- higher than the amount properly due, then you must account for the higher amount in your records, unless you correct the error with your customer by issuing a credit note
- lower than the amount properly due, then you must account for the correct amount of VAT due whether or not you correct the error with your customer (for example, by issuing a supplementary invoice for the amount undercharged)
You can find more information on credit notes in sections 18 and 19 of VAT Notice 700.
3.3 Invoices you’ve received
If the amount of VAT shown on an invoice you received is:
- too high, then you must go back to your supplier for a replacement invoice reducing the amount of VAT charged
- too low, then you must go back to your supplier for a replacement invoice increasing the amount of VAT charged
If the amount of VAT shown on an invoice you received is incorrect and your VAT return is due you must:
- submit the return accounting for the amount of VAT shown on the invoice
- not adjust the VAT
You can adjust your next VAT return if both the following apply:
- you’ve received relevant documentation, like a credit note or replacement invoice
- this is within the error correction limits described in section 4
4. Correcting VAT errors on a return already submitted
4.1 Penalties for errors
You’ll face penalties for any errors in your return that are careless or deliberate. You will not need to pay a penalty if you make an error despite taking reasonable care.
An error is careless if you fail to take the care and attention that could be expected from a reasonable person in the circumstances.
If you discover an error after making a return that was neither careless or deliberate when you sent it to HMRC, you must take steps to correct it. If you do not, we’ll treat the error as careless.
If you can correct an error that you made despite taking reasonable care using method 1 (read section 4.3), you will not need to make a disclosure to HMRC.
If you correct a careless error using method 1, you must tell us about it, regardless of its size or value, to receive a lower penalty. The penalty will be lower if you tell us about an error before you have reason to believe that we’ve found out about it.
If you’ve adjusted an error under method 1, but you’re not sure whether HMRC would consider it careless, you can still either:
- send us an error correction notification
- write to us to make a disclosure
You must notify HMRC about any deliberate errors, in writing, or using an error correction notification under method 2 (read section 4.4). You should provide a description of the error, explaining how and why it happened. You must also include the full amount of the inaccuracy. You can continue on a separate sheet if necessary.
If you send a letter, it should contain the same information you’d need to include on an error correction notification. You must also tell us that you’ve made the adjustment on your return.
Late payment interest will apply if an error means that you did not pay all the VAT payable by the due date for the VAT period. Learn more about VAT penalties and interest.
4.2 Methods for correcting errors
There are 2 methods for correcting errors.
Method 1 is for either:
- errors of a net value that do not exceed £10,000
- errors of a net value between £10,000 and £50,000 that do not exceed the limit described in section 4.3
Method 2 is for either:
- errors of a net value between £10,000 and £50,000 that exceed the limit in section 4.3
- net errors greater than £50,000
You can also choose to use method 2 to report errors of any size.
4.3 Method 1
You can use this method to adjust your VAT account, if you’ve accounted for too much or too little tax and include the value of that adjustment on your current VAT Return, as long as the:
- net value of errors found on previous returns does not exceed £10,000
- net value of errors found on previous returns is between £10,000 and £50,000 but does not exceed 1% of the box 6 (net outputs) VAT Return declaration due for the return period in which you discover the errors
Work out the net value of VAT errors on previous returns, by calculating the:
- total amount due to us, if any
- total amount due to you, if any
If the difference between the 2 figures is greater than £10,000 and exceeds 1% of the box 6 (net outputs) VAT Return declaration due for the current return period during which you discovered the error, you must use method 2.
You must always use method 2 if the net errors exceed £50,000 or if you made the errors on previous returns deliberately.
Correcting errors using method 1 is not a disclosure for the purposes of the penalty rules described in section 4.1. If you consider that the error corrected using method 1 was a result of careless conduct you will not be able to gain the maximum reduction of the penalty unless you also tell us separately in writing, either by letter or by completion of an error correction notification, about both:
- the error
- your grounds for seeking a reduction to the penalty
This will be an unprompted or prompted disclosure depending on the circumstances.
4.4 Method 2
You must use this method and notify HMRC separately of the error if the:
- net value of errors found on previous returns is between £10,000 and £50,000 and exceeds 1% of the box 6 (net outputs) VAT Return declaration due for the current return period during which you discovered the error
- net value of errors found on previous returns is greater than £50,000
- you made the errors on previous returns deliberately
You can also use this method for errors of any size which are below the limits in section 4.3, instead of a method 1 error correction.
If you’re not sure which method to use, you can check how to tell HMRC about VAT Return errors.
4.5 How to tell HMRC about an error
You can report errors to HMRC online. You’ll need to include the following information:
- how each error arose
- the VAT accounting period in which it occurred
- if it was an input tax or output tax error
- the VAT underdeclared or overdeclared in each VAT period
- how you worked out the VAT underdeclared or overdeclared
- whether any of the errors resulted in you paying us an amount that was not due
- the total amount to be adjusted
If you’re making a refund claim, we can only accept it if you provide all this information.
4.6 If you cannot use the online service
Notifications in writing must include your VAT registration number. Send them to the VAT Error Correction Team by post at:
BT VAT
HMRC
BX9 1WR
You can also contact us by:
- telephone: 0300 200 3700
- email: inbox.btcnevaterrorcorrection@hmrc.gov.uk
4.7 The time limit for correcting errors
The time limit for error corrections is 4 years from the:
- end of the prescribed accounting period in which the error occurred for under-declared and over-declared output tax and over-claimed input tax
- due date of the return for the prescribed accounting period in which the error occurred for under claimed input tax
There are 2 exceptions:
- time of supply (tax point errors) where you’ve declared an amount of VAT on the return that immediately precedes or follows the return for which the amount was due, provided the later return is within the 4-year time limit
- the 4-year time limit does not apply to deliberate errors
4.8 When to correct errors
As soon as you find an error, record it in your VAT records for correction.
You may find it useful to keep a separate record in your current VAT account that you can update if you discover errors. You should:
- show the date you discover the error
- show the period in which the error occurred
- identify any related documentation
- identify whether the error was output or input tax related
The record will help you decide whether method 1 or method 2 is the appropriate method to use when correcting errors. You should normally wait until the end of the current accounting period before making this decision. However, if an individual error is so large that the 1% box 6 test or £50,000 limit referred to in section 4.4 will be breached, you must immediately make an error correction notification to HMRC, using method 2.
4.9 If you do not correct VAT errors and HMRC finds them
If we find underdeclared VAT on your returns, we’ll assess for the tax due and may charge you interest. To avoid a penalty, you must disclose the full details of any errors before we begin to make enquiries into your VAT affairs.
Enquiries normally begin when we make an appointment to inspect your records. We’ll accept disclosures for penalty purposes after this point, unless we have reason to believe that you already knew about the errors, and only disclosed them because of our enquiries.
You should make an error correction by following the procedures in sections 4.3 and 4.4.
You can find further information:
Read section 4.1 for information about penalties for errors in a VAT Return.
4.10 Correcting errors that have little effect on the net VAT that you declared
There may be times when large output and input tax errors have a small or no effect on the net VAT due on returns. If the net value of errors you’ve found on previous VAT Returns is within the limit shown in section 4.2, you can choose either method 1 or 2 (described in paragraphs 4.3 and 4.4) to correct the errors. For us to consider any reduction to a penalty, you must tell us if you’ve made a careless or deliberate error in individual VAT Return declarations, no matter the size or value.
4.11 Adjustments that are not errors
Adjustments you need to make as part of the normal operation of VAT accounting are not errors, and are covered by other VAT accounting provisions. This is as long as:
- they’re accurate
- you make them at the right time
These accounting adjustments include:
- retail scheme annual adjustments, or other adjustments required when a person stops using a particular retail scheme
- adjustments under the Capital Goods Scheme
- an approved estimation procedure
- partial exemption adjustments
- partial exemption clawback and payback adjustments
- exports and supplies of goods within the European Commission
- issuing or receiving credit and debit notes
- claims for bad debt relief
- pre-registration and post deregistration expenses
- adjustments for valid prompt payment discounts
If the original accounting adjustment was incorrect, or made at the wrong time, you’ll need to make error corrections in the normal way.
5. How to claim a refund
5.1 Accounting for output tax that was not due
If you’ve accounted for output tax to HMRC that was not due and this was within the last 4 years, depending on the amount (read section 4.2) you can either:
- adjust your return for the period in which you discover the over declaration
- claim a refund by making an error correction notification
You should correct all other known errors at the same time.
Read section 4 for information about both methods and how the 4-year time limit works. We will not pay a claim which would result in your unjust enrichment. This is where you’ve:
- passed the mistaken VAT charge on to your customer who bore the burden of the mistaken charge but are unable, or do not intend, to pass on to them any repayment resulting from the claim
- not suffered any loss or damage by charging a higher price than you needed to
Read further information about unjust enrichment and the arrangements for reimbursing customers in section 9.
5.2 If you’ve been charged output tax incorrectly
If you think you’ve been wrongly charged an amount as VAT by your supplier, this is a commercial matter. You should seek a refund from your supplier. If you overpaid your supplier and your supplier accounted to HMRC for a corresponding amount, they can make a refund claim to HMRC in order to reimburse you. Claims to HMRC by suppliers for amounts overpaid as VAT are limited to a 4-year period. Read section 4.7 for more information on the time limit for correcting errors.
6. Not claiming enough input tax on your previous returns
6.1 Claiming input tax
You can claim input tax after you have both:
- incurred the input tax
- received the associated VAT invoice
If you could not claim input tax in any tax period because you did not hold the VAT invoice at the time, you can claim it in a later period on your VAT return. This must be within the 4-year time limit described in section 4.7.
If you had the necessary evidence in the tax period but did not claim, then that return is in error.
7. What happens after you make an error correction notification
7.1 When we may contact you
We may need to contact you to clarify the details of your notification before we process it. In some cases it may be necessary to visit you to verify it. We’ll agree a date and time for the visit with you.
7.2 How we’ll notify you
Once we’ve processed your error correction, we’ll send you a notice confirming the amount and any interest calculated on it. We’ll also send a statement showing the current balance payable to us (including any interest), or repayable to you.
If your correction generated a repayment that is subject to the unjust enrichment provisions detailed in section 9, we’ll not send you these documents, but will write to you to tell you.
If you do not hear from us within 40 working days, contact the VAT Error Correction Team using the contact details in section 4.6 to make sure they’ve received your error correction notification.
7.3 Payments or repayments of amounts
If we’ve notified you in line with section 7.2 and the statement shows a current balance payable to us, it will include details of ways to pay.
7.4 How we’ll pay net amounts due to you
If we’ve notified you in line with section 7.2 and the statement shows a current balance payable to you, it will include details of how we’ll make the payment.
8. If you disagree with a decision or ruling
8.1 How to make a claim if you disagree with our decision
Once we’ve given you a decision or ruling concerning your VAT liabilities, we’ll normally reject any claim from you which challenges our decision or ruling.
If your claim is formally rejected you can apply for a review of our decision. You have 30 days to apply.
If you do not want a review, or if you do not agree with the result of the review, you can appeal to the First-tier Tribunal to decide the matter.
If you’ve made a valid claim and appeal, and our decision is overturned, you’ll be entitled to a refund.
If you do not appeal, any future claim will be:
- a new claim
- subject to the time limits in section 4.7

9. Unjust enrichment and the reimbursement scheme
9.1 What unjust enrichment is
For tax purposes, unjust enrichment is when someone benefits from a tax refund, but their customer bore the cost for the amount of tax wrongly charged.
We may refuse a claim for over-declared output tax if we find that you’ve passed the economic burden on to your customer.
We will not refuse a claim on the grounds of unjust enrichment, if you both:
- agree to reimburse your customer
- can meet the conditions of HMRC’s reimbursement scheme
For this purpose, a customer includes everyone you’ve made sales to, whether they’re registered for VAT or not.
9.2 HMRC’s reimbursement scheme
To meet the conditions of the reimbursement scheme, you must:
- sign an undertaking in the format set out in section 10 of this notice — you cannot amend this once you’ve signed it
- refund all of your customers within 90 days
- repay any residual amounts not returned to your customers after 90 days to HMRC within 14 days (we will not send reminders) — if you fail to do this we’ll assess for the residue
- pass any interest paid with the refunds to your customers — this is subject to the same terms and conditions as the refund
You cannot use the reimbursement scheme if your customer is VAT registered and recovered the overcharged VAT as input tax.
You must also keep the following records, the:
- names and addresses of the customers you intend to reimburse
- total amount of money paid to each of your customers
- amount of interest, if applicable, paid to each of your customers
- date you refunded the money
You must not take out of the refund any costs you incur in administering the scheme. If you do, we’ll normally assess you.
You can still use the scheme even if you’re no longer registered for VAT. You’ll be subject to the same terms and conditions as VAT-registered businesses.
9.3 Repaying interest to you
If you’re due a repayment, you may also receive interest. Read more about repayment interest on VAT credits or overpayments.
If we pay interest, this will be subject to the same terms and conditions as money refunded under the scheme. You must pass this on to your customers in full.
You must pay back any interest that you’ve been unable to pass on to your customers within the specified time limit of 14 days.
9.4 If you do not wish to use the reimbursement scheme
If you agree that you would be unjustly enriched but do not want to, or cannot refund your customers (for example, if you cannot identify them), then you cannot get a refund from us.
The existence of the scheme does not affect your right to claim that you would not be unjustly enriched, or appeal to the tribunal if we reject your claim.
If the tribunal finds in our favour you can still use the scheme.
10. Undertaking for the reimbursement scheme
In relation to a claim for £(insert amount) made on (insert date) relating to prescribed accounting period(s) (insert accounting period(s)) made under section 80 VATA 1994. In accordance with the terms of section 80A VATA 1994 and regulations 43A to 43G of the Value Added Tax Act Regulations 1995, Part VA Reimbursement Arrangements (Statutory Instrument 1995/2518), I agree to comply with the following reimbursement arrangements.
‘I, the undersigned, can identify the names and addresses of consumers whom I intend to reimburse. I will reimburse those persons, in cash or by cheque, all of the amount credited by HMRC under section 80(1) or 80(1A) of the VAT Act 1994, together with any associated interest, without any deduction, for whatever purpose, within 90 days of receiving the credit and I understand that I cannot use the credit for any other purpose. Furthermore, where some or all of the credited amount to be reimbursed has been paid or repaid to me and I have not reimbursed some or all of it to consumers, I will, without reminder, notify HMRC and return the balance together with any associated interest to HMRC within 14 days of the 90 days expiring. Where the credited amount has not been paid or repaid to me, and I have not reimbursed some or all of it to consumers, I will notify HMRC of that amount of credit and associated interest I have not reimbursed to consumers within 14 days of the 90 days expiring. I will keep the necessary records as set out in the Regulations and I will comply with any notice given to me by HMRC about producing the records I am required to keep.’
