VAT Returns Explained: A Beginner's Guide

Value Added Tax (VAT) is one of the most important taxes for UK businesses, yet it is also one of the most misunderstood. This guide covers everything a beginner needs to know about VAT returns — from registration to filing.

What Is VAT?

VAT is a consumption tax charged on most goods and services sold in the UK. It is collected by businesses on behalf of HMRC. The current standard rate is 20%, with reduced rates of 5% and 0% for certain items.

When your business charges VAT to customers (output VAT) and pays VAT on purchases (input VAT), the difference is what you owe to — or are owed by — HMRC.

Do I Need to Register for VAT?

You must register for VAT if:

• Your taxable turnover exceeds £90,000 in any 12-month rolling period (as of April 2024)
• You expect to exceed the threshold within the next 30 days

You can register voluntarily even if below the threshold. This can be beneficial if:

• Your customers are VAT-registered businesses (they can reclaim your VAT)
• You want to reclaim VAT on business purchases
• It makes your business appear more established

What Is a VAT Return?

A VAT return is a form submitted to HMRC (usually every quarter) that reports:

• The total VAT you have charged to customers (output VAT)
• The total VAT you have paid on purchases (input VAT)
• The net difference — either a payment to HMRC or a refund

The 9 Boxes

Every VAT return has 9 boxes:

Box	Description
1	VAT due on sales and other outputs
2	VAT due on acquisitions from EU
3	Total VAT due (Box 1 + Box 2)
4	VAT reclaimed on purchases and other inputs
5	Net VAT to pay or reclaim (Box 3 - Box 4)
6	Total value of sales, excluding VAT
7	Total value of purchases, excluding VAT
8	Total value of EU supplies, excluding VAT
9	Total value of EU acquisitions, excluding VAT

VAT Filing Deadlines

Most businesses file VAT returns quarterly. The return and payment are due one month and 7 days after the end of the VAT period.

For example, if your VAT quarter ends on 31 March:

• Filing and payment deadline: 7 May

Late Filing Penalties

HMRC uses a points-based penalty system for late VAT returns:

• Each late submission earns a penalty point
• After reaching the threshold (4 points for quarterly filers), you receive a £200 penalty
• Additional £200 penalties for each subsequent late submission until points are reset

Making Tax Digital (MTD)

Since April 2022, all VAT-registered businesses must comply with Making Tax Digital. This means:

• You must keep digital records using MTD-compatible software
• You must submit VAT returns digitally through the software
• You cannot manually type figures into HMRC's online portal

Popular MTD-compatible software includes Xero, QuickBooks, Sage, and FreeAgent.

Common VAT Schemes

Flat Rate Scheme

Instead of tracking VAT on every purchase, you pay a fixed percentage of your gross turnover. This simplifies record-keeping. The percentage varies by industry (e.g., 14.5% for computer and IT consultancy).

Best for: Businesses with low input VAT (few purchases).

Cash Accounting Scheme

You account for VAT based on when you receive and make payments, rather than when invoices are issued. This helps with cash flow.

Best for: Businesses with slow-paying customers.

Annual Accounting Scheme

You make advance VAT payments throughout the year and file just one return at the end.

Best for: Businesses wanting simpler administration.

Common Mistakes to Avoid

1. Claiming VAT on non-business expenses — only business purchases qualify
2. Not keeping valid VAT invoices — you need proper invoices to reclaim input VAT
3. Missing the flat rate first-year discount — new users get 1% off their flat rate in year one
4. Forgetting to deregister — if turnover drops below £88,000, consider voluntary deregistration
5. Not using MTD-compatible software — this is now mandatory

Key Takeaways

• Register for VAT when turnover exceeds £90,000 (or voluntarily if beneficial)
• File VAT returns quarterly (usually) — deadline is 1 month and 7 days after period end
• Making Tax Digital compliance is mandatory for all VAT-registered businesses
• Consider VAT schemes like the Flat Rate Scheme to simplify your obligations
• Keep accurate, digital records of all VAT transactions
• Plan your cash flow — VAT payments can be significant

VAT can seem daunting at first, but with the right systems in place, it becomes a routine part of running your business.
