Common VAT Errors

5/12/2025

If you're thinking of becoming VAT registered, or have recently registered, find out what you need to know to avoid making common VAT errors.

Value Added Tax (VAT) can be an essential part of doing business, but it's an area that often trips up business owners, especially small businesses and start ups. At DWilkinson&Company, we work closely with tradespeople, shop owners, consultants, and other small business owners across Rochdale and Lancashire, helping them stay compliant with VAT rules while avoiding costly mistakes.

This blog highlights common VAT errors we frequently see and explains how our experienced team can help you with VAT registration, bookkeeping, filing, and compliance with the Making Tax Digital (MTD) for VAT rules.

Common VAT errors that cost businesses money

Many business owners assume that VAT is straightforward - you register, charge VAT on sales, claim it on purchases, and pay the balance to HMRC. But the reality is much more complex; even simple mistakes can lead to penalties, interest charges, and investigations.

Here are some of the common VAT errors we see among Rochdale businesses:

Missing the VAT registration threshold

One of the most common mistakes is not registering for VAT on time. Businesses must register when their VAT taxable turnover exceeds £90,000 (the VAT threshold as of 1 April 2024) during any rolling 12-month period. Many businesses only look at their year-end figures, missing the fact that they've crossed the threshold earlier in the year. This can lead to late registration penalties and a backlog of VAT due.

Incorrectly claiming VAT on expenses

Another frequent error is claiming VAT on purchases that are not eligible, for example, client entertainment expenses, certain car purchases, or invoices without valid VAT numbers. Claiming VAT incorrectly can trigger a VAT inspection and lead to HMRC clawing back the VAT claimed, plus penalties.

Charging the wrong VAT rate

Not all goods and services carry the standard 20% VAT rate. Some have reduced rates (5%), zero rates, or are VAT exempt. We often see businesses charging the wrong VAT rate, leading to underpaying or overpaying VAT.

Failure to issue valid VAT invoices

VAT registered businesses must issue VAT invoices with specific details, including their VAT number, invoice date, and a breakdown of VAT charged. Missing or incorrect invoices can result in disallowed VAT claims.

Poor bookkeeping and record-keeping

Without up to date and accurate bookkeeping, it's easy to miss VAT deadlines, miscalculate liabilities, or lose track of which invoices have been included in a VAT return. Poor records are a major source of common VAT errors.

Not complying with Making Tax Digital (MTD) for VAT

Since April 2022, all VAT registered businesses must comply with MTD for VAT, which means keeping digital records and filing VAT returns directly to HMRC using MTD compatible software. Failure to comply with MTD can result in HMRC charging you penalties.

Misunderstanding the VAT Domestic Reverse Charge for Construction Services

The VAT domestic reverse charge applies to most construction services under the CIS (Construction Industry Scheme). Instead of charging VAT on invoices to other VAT registered contractors, subcontractors must now apply the reverse charge, meaning the customer accounts for the VAT rather than the supplier. This is one of the common VAT errors we see among tradespeople, who either incorrectly charge VAT or fail to show the correct wording on invoices.
