VAT Returns in the UK: Deadlines, Penalties, and How to Stay Compliant

Value Added Tax (VAT) plays a crucial role in the UK’s tax system and applies to most goods and services sold in the country.

Businesses of all sizes are required to comply with VAT regulations, which include submitting returns to HM Revenue and Customs (HMRC) on time.

Getting VAT reporting right is essential to avoid penalties and protect your business’s reputation. Late or inaccurate submissions can lead to costly fines, interest charges, and harm your financial credibility in the long run.

In this article, we’ll cover the essentials of VAT returns—key deadlines, common penalties for late submissions, typical mistakes to watch out for, and practical tips to help you stay on top of compliance.

VAT Return Deadlines

VAT returns are a key part of your business’s tax obligations in the UK, and understanding the different deadlines is crucial to avoid penalties.

Your business must submit its returns on time to remain compliant with HM Revenue and Customs (HMRC).

Standard VAT Return Periods

For most businesses, VAT returns are filed on a quarterly basis. The VAT period typically lasts for three months, and the return must be submitted to HM Revenue and Customs (HMRC) by one month and seven days after the period ends. 

For example, if the VAT period ends on 31st March, the return is due by 7th May. Timely submission is essential to avoid penalties, and payments are also due by this deadline.

Alternative VAT Accounting Schemes

1. Annual Accounting Scheme

Under the Annual Accounting Scheme, businesses with an annual turnover of up to £1.35 million can file just one VAT return per year. 

However, they are required to make interim payments throughout the year based on estimated VAT liability. The return is due 9 Months and 7 Days after the end of the accounting year.

This scheme offers more flexibility but requires businesses to manage their VAT payments more carefully to avoid underpayment.

2. Monthly VAT Returns for Repayment Traders

Businesses that regularly receive VAT repayments can opt for monthly VAT returns. This option allows them to receive repayments faster, improving cash flow.

Monthly submissions are due days 1 Month and 7 days after the end of each VAT period, ensuring timely reimbursement for VAT refunds.

Penalties for Missing VAT Deadlines

The UK’s HM Revenue and Customs (HMRC) has implemented a penalty points-based system to encourage timely VAT returns and payments.

This system aims to penalise businesses for late submissions or non-compliance, helping ensure that VAT obligations are met properly and on time.

Earning Points for Missed Submissions

Under the penalty points system, businesses accumulate points each time they fail to submit a VAT return by the due date. 

The number of points awarded depends on the frequency of VAT returns: 

• Quarterly 
• Monthly
• Annually 

Once your business reaches a certain number of points, penalties are triggered. For example, after accumulating four points for quarterly submissions, you will face a fine.

The threshold varies, and your business must be vigilant about keeping its submissions on time to avoid unnecessary penalties.

Financial Penalties for Persistent Non-Compliance

If the threshold of penalty points is reached, your business will incur a fixed fine. The fine increases with the number of missed submissions.

In addition, if your business continues to miss deadlines or is repeatedly non-compliant, further fines may be applied, leading to significant financial costs. 

This tiered penalty structure aims to incentivise businesses to submit returns on time consistently.

Penalties for Late VAT Payments

In addition to late submissions, HMRC imposes interest charges on overdue VAT payments. Interest accrues daily from the day after the due date until the payment is made.

These interest charges can quickly add up, increasing the overall financial burden on non-compliant businesses and underscoring the importance of timely payment.

Common Mistakes in VAT Filing

Mistakes in VAT filing can lead to penalties and financial inaccuracies. Here are a few common errors you should look for to avoid:

• Submitting Incorrect VAT Figures: 
  Overestimating or underestimating VAT liabilities can result in financial discrepancies and the need for adjustments, leading to penalties or interest charges.
• Failing to Claim Eligible VAT Refunds: 
  Many businesses sometimes  overlook the opportunity to reclaim VAT on allowable expenses, which reduces cash flow and the overall business profitability.
• Using Outdated Accounting Methods or Software: 
  Non-compliance with Making Tax Digital (MTD) requirements by using outdated or incompatible accounting software can result in fines. MTD-compliant tools are essential for accurate VAT reporting and filing.
• Forgetting to Reconcile VAT Accounts: 
  Before submitting VAT returns, it’s critical that you reconcile all VAT accounts to ensure the figures are accurate. Failure to do so can lead to errors in reporting and missed opportunities for refunds.
• Incorrect VAT Rate Application: 
  If any business applies the wrong VAT rate to goods or services, it can lead to miscalculations, resulting in potential penalties for the business.
• Not Keeping Adequate Records: 
  Failing to maintain proper VAT records can complicate the filing process for your business and may lead to issues during audits.

Avoiding these common mistakes will help you maintain compliance and prevent any unnecessary penalties.
