Incorrect VAT coding, missing invoices, duplicated purchases, weak digital records and transactions entered in the wrong period can all lead to inaccurate returns.

Seven VAT Mistakes Small Businesses Make
Using The Wrong VAT Treatment
Not every sale or purchase has the same VAT treatment. Businesses can make errors by applying the wrong rate, treating an exempt supply as taxable, or assuming that VAT on every cost can be reclaimed. Once the coding is wrong, the return can also be wrong. BES Accountancy can review transaction coding, source documents and VAT settings before submission.
Reclaiming VAT Without Adequate Evidence
Input VAT claims generally need appropriate documentary evidence. A bank payment alone does not automatically establish that VAT can be reclaimed. Missing or incorrect supplier invoices can therefore create problems. Good bookkeeping means matching purchase entries to suitable evidence and resolving gaps before filing.
Missing Sales Or Recording Purchases Twice
A missing sales invoice can understate output VAT. A duplicated purchase invoice can overstate recoverable VAT. These mistakes are more likely when bookkeeping is updated in batches or data comes from several sources. Regular reconciliation between sales, purchases, bank activity and the VAT account is an effective control before a return is finalised.
Weak Making Tax Digital Records
HMRC requires specified VAT records to be kept digitally under Making Tax Digital unless an exemption applies. Where more than one software product is used, required transfers of VAT data must use digital links rather than manual copying and pasting. BES Accountancy has expertise in Xero and QuickBooks and can support cleaner digital bookkeeping and consistent VAT coding. HMRC’s guidance on keeping VAT records explains the current requirements.
Putting Transactions In The Wrong VAT Period
VAT reporting is not always determined by the date money reaches the bank. The correct period can depend on time of supply rules and, where relevant, the accounting scheme in use. Posting a transaction to the wrong period can shift VAT between returns and create reconciliation differences later.
Filing Or Paying Late
HMRC operates a points based system for late VAT Returns. Once the relevant threshold is reached, a £200 penalty applies, with further £200 penalties for subsequent late submissions while the business remains at the threshold. Late payment penalties can also apply when VAT remains unpaid more than 15 days after the due date.
Finding An Error And Doing Nothing
A discovered VAT error should not simply be carried forward. HMRC allows certain errors from earlier returns to be corrected on a later VAT Return, subject to limits. Net errors of £10,000 or less can generally be adjusted on the next return. Errors between £10,000 and £50,000 can also qualify if they are less than 1 per cent of total sales. Errors outside those limits, and deliberate errors, must be notified separately.
How Better VAT Bookkeeping Protects Cash Flow
VAT is not just a filing exercise. If the VAT account is inaccurate, a business can misunderstand how much cash is genuinely available, overlook recoverable VAT or face an unexpected liability close to the payment date.
Accurate bookkeeping, regular reconciliations and well configured digital accounting give owners better visibility before a return is filed. They also make financial information easier to prepare for accountants, lenders and other professional advisers.
Besnik Vata, Director of BES Accountancy, explains:
“Accurate VAT reporting starts with complete records, consistent coding and regular reconciliation. Problems are easier to correct when they are identified early.”
