What Is a VAT Return?

A VAT return is a summary submitted to HM Revenue & Customs showing:

Total sales and purchases
VAT owed to HMRC
VAT reclaimable
Net VAT payable or refundable

Most VAT-registered businesses must submit returns quarterly under the Making Tax Digital (MTD) rules.

You can view the HMRC official guidance here, which goes into more details about filling in your VAT return (VAT Notice 700/12)

Who Needs to Submit VAT Returns?

You must register for VAT if your taxable turnover exceeds the UK threshold (currently £90,000 – confirm latest threshold before publishing). Once registered, you are legally required to:

Keep digital VAT records
Use MTD-compatible software
Submit VAT returns electronically

Failure to comply can lead to penalties and interest charges.

Key VAT Deadlines (UK)

For most businesses:

VAT returns are due 1 month and 7 days after the end of your VAT period.
Payment must also clear by this date.
Direct Debit users must ensure funds are available in time.

Missing deadlines may trigger default surcharges or penalty points under HMRC’s new penalty regime.

You can calculate your VAT payment deadline using the Gov.uk calculator linked here.

Common VAT Mistakes Small Businesses Make

1. Mixing Personal & Business Transactions

This causes reconciliation issues and incorrect VAT claims.

2. Claiming VAT Without Valid Invoices

HMRC requires proper VAT invoices to support claims.

3. Incorrect VAT Rates

Standard rate (20%), reduced rate (5%), and zero-rated supplies must be correctly applied.

4. Poor Record-Keeping

Under MTD, digital record keeping is mandatory.

How Cloud Bookkeeping Simplifies VAT Returns

Modern cloud accounting software can be used to automate many of the processes below. Some of the main software in use today.

Processes which it can help automate:

VAT calculations
Digital record storage
MTD-compliant submissions
Real-time financial visibility

VAT for Contractors & CIS Businesses

Professional bookkeeping ensures:

Correct CIS deductions
Proper reverse charge application
Accurate VAT box reporting

You can read more in our guide to CIS here.

When Should You Get Professional VAT Support?

Consider hiring a bookkeeper if:

You’re unsure about MTD compliance
You regularly submit late VAT returns
Your bookkeeping is not reconciled monthly
You’ve received penalty notices
You’re growing and turnover is increasing
