Understanding VAT: A Vital Part of Running a Limited Company

VAT (Value Added Tax) is an essential consideration for many UK limited companies. Whether you’re approaching the £85,000 registration threshold or you’re already VAT registered, compliance is key to avoiding penalties and maintaining smooth operations. Despite its importance, VAT remains one of the most misunderstood areas of UK tax law, leading to costly errors.

At DSR Ashburns Accountants, we often see limited companies fall into the same VAT traps. Here, we highlight the most common VAT mistakes and how to avoid them.

1. Missing the VAT Registration Threshold

One of the most frequent mistakes small businesses make is failing to register for VAT on time. If your VAT taxable turnover exceeds £85,000 in any rolling 12-month period, you’re legally required to register. Unlike the tax year or calendar year, this refers to any consecutive 12 months—which can catch many businesses off-guard.

Failure to register on time can result in penalties and backdated VAT payments. It’s crucial to monitor your turnover closely, especially during periods of rapid growth or seasonal peaks.

2. Charging VAT Incorrectly

Once registered, your business must charge VAT correctly on all applicable goods and services. Mistakes can occur when businesses invoice items which are zero-rated or exempt but accidentally apply the standard VAT rate. Conversely, some companies undercharge VAT or forget to charge it at all.

Common issues include:

• Applying zero-rate VAT to standard-rated services.
• Charging VAT on exempt items like insurance or education-related services.
• Failing to update prices or invoices after VAT registration.

It’s vital to understand whether your goods or services attract standard, reduced, or zero-rate VAT, and to update your invoicing systems accordingly.

3. Reclaiming VAT Incorrectly

Another mistake we often see is businesses reclaiming VAT they are not entitled to. You can only reclaim VAT on business-related purchases, not personal expenses. Furthermore, if a supplier’s invoice doesn’t include a valid VAT number, HMRC can reject your claim.

Missteps in this area include:

• Reclaiming VAT on entertainment expenses for clients.
• Including VAT on supplies used for both personal and business use without apportioning it.
• Claiming VAT on purchases from businesses not registered for VAT.

Proper record-keeping and ensuring all claims are legitimate will save time and reduce the risk of a VAT investigation.

4. Ignoring the VAT Flat Rate Scheme Rules

The VAT Flat Rate Scheme can simplify accounting for small businesses, particularly limited companies with a turnover under £150,000 (ex VAT). However, misapplying the flat rate or misunderstanding which turnover figures to apply the rate to can skew your VAT liability.

Companies often forget that even under the Flat Rate Scheme, VAT must still be charged at the standard rate on sales invoices. Their payment to HMRC is then calculated using the flat rate percentage. Misreporting these figures can highlight discrepancies during a VAT inspection.

5. Late or Incorrect VAT Returns

Filing your VAT returns late or submitting incorrect figures can trigger penalties from HMRC. Automation tools can help, but they’re only effective if they are set up correctly and based on accurate data.

Ensure you:

• Submit your VAT returns by the deadline—usually one calendar month and seven days after the end of your accounting period.
• Keep digital records in line with Making Tax Digital (MTD) requirements.
• Double-check input and output VAT figures before filing.

6. Not Staying Compliant with Making Tax Digital (MTD)

All VAT registered businesses are now required to follow MTD rules by keeping digital records and using compatible software to submit returns. Yet some companies are still not fully compliant.

Non-compliance with MTD not only leads to potential fines but also makes your business less efficient. Switching to compliant software and proper bookkeeping support can streamline your VAT process and reduce the chance of errors down the line.
