Common VAT Return Mistakes

Submitting a VAT return may seem straightforward, but even small mistakes can lead to incorrect VAT payments, HMRC queries, interest or penalties. Whether you are a small business or a growing company, getting your VAT accounting right is essential for staying compliant.

Understanding the most common VAT return mistakes can help your business maintain accurate records and avoid unnecessary problems with HMRC.

1. Using the Wrong VAT Rate

One of the most common VAT errors is applying the wrong VAT rate to sales or purchases.

Depending on the goods or services involved, a transaction could be:

Applying the wrong treatment can result in VAT being overpaid or underpaid. Businesses should ensure that the correct VAT treatment is applied to every transaction.

2. Claiming VAT Without Valid Evidence

Businesses generally need appropriate evidence, such as a valid VAT invoice, to support VAT being reclaimed on purchases.

A common mistake is claiming input VAT using incomplete documentation or where the supplier has not correctly charged VAT.

Keeping accurate invoices and supporting records makes your VAT return easier to prepare and helps if HMRC reviews your records.

3. Claiming VAT on Non-Allowable Expenses

Not every business expense automatically allows you to reclaim all the VAT charged.

Restrictions can apply to certain expenses, including some:

Before reclaiming VAT, businesses should check whether the expense qualifies and whether any restriction or apportionment is required.

4. Mixing Business and Personal Expenses

Using the same accounts or payment methods for business and personal spending can make VAT bookkeeping unnecessarily complicated.

Where an expense has both business and private use, you may only be entitled to reclaim the appropriate business proportion of the VAT.

Separating business transactions wherever possible makes record-keeping and VAT calculations much clearer.

5. Getting the Reverse Charge Wrong

The VAT reverse charge can cause confusion, particularly for businesses operating within industries such as construction or dealing with certain international transactions.

Incorrectly applying or failing to apply the reverse charge can affect both the VAT return and the accounting records behind it.

Businesses should understand whether the reverse charge applies before issuing or processing an invoice.

6. Recording Transactions in the Wrong VAT Period

Including sales or purchases in the incorrect VAT period can result in inaccurate returns.

The correct VAT period can depend on factors such as the tax point, invoice date, payment date and the VAT accounting scheme being used.

Regular bookkeeping helps ensure transactions are recorded in the appropriate period rather than being corrected months later.

7. Missing VAT Return and Payment Deadlines

Missing an HMRC VAT deadline can have financial consequences.

Businesses should keep track of both their VAT filing and payment obligations. Even where there is little or no VAT to pay, a return may still need to be submitted.

Setting reminders and keeping bookkeeping up to date can significantly reduce the risk of late submissions.

8. Poor VAT Record-Keeping

Incomplete records are one of the easiest ways for VAT problems to develop.

Businesses should maintain appropriate records of sales, purchases, VAT invoices, credit notes and other information supporting the figures reported to HMRC.

Good VAT record-keeping also makes it easier to identify discrepancies before the return is submitted.

9. Making Tax Digital Errors

Most VAT-registered businesses are required to follow Making Tax Digital (MTD) for VAT requirements.

Using incompatible software, failing to maintain the required digital records or breaking required digital links can create compliance issues.

Businesses should ensure their accounting processes and software remain suitable for MTD VAT compliance.

10. Not Correcting VAT Errors Properly

Finding a mistake after submitting a VAT return does not necessarily mean it should simply be ignored or adjusted without checking the rules.

How a VAT return error should be corrected can depend on factors such as the nature, value and circumstances of the mistake.

If you discover an error, it is important to determine the correct method of disclosure or adjustment under HMRC’s rules.
