Vat records – what do you need to keep

VAT records can feel like a mountain of paperwork, but understanding what you actually need to keep—and for how long—takes a lot of the stress out of compliance. Whether you’re a sole trader, partnership, or limited company, HMRC has clear rules about record retention, and getting it right protects you from penalties and makes tax time considerably easier.

What records you must keep

HMRC requires you to keep records that allow them to verify your VAT position. This isn’t vague—they’re quite specific about what falls into this category.

Purchase invoices form the backbone of your input tax claims. You’ll need to retain invoices from all suppliers, including those where you’ve claimed VAT back. These should show the supplier’s name, their VAT registration number, the invoice date, a description of goods or services, and the VAT amount. Without these, you can’t support your return to HMRC.

Sales invoices or till records are equally essential. If you issue invoices, keep copies. If you operate a till system, you need transaction records that show the date, customer details (where applicable), description of items sold, and VAT amount. For e-commerce businesses, order confirmations and despatch records also count.

Bank statements and payment records document the money flowing in and out of your business. These cross-reference with your sales and purchases, helping HMRC spot any discrepancies. If you use accounting software that’s connected to your bank, this integration can significantly reduce administrative burden.

Ledgers and accounting records sit at the core of VAT compliance. Your purchase and sales ledgers, or equivalent digital records, must show transactions in sufficient detail. If you use cloud-based accounting software compliant with Making Tax Digital (MTD) rules, this requirement is satisfied by your software’s records.

Import and export documentation applies if you trade across borders. Keep customs declarations, Intrastat records (for EU trade up to your relevant threshold), and any supporting paperwork. Rules have evolved considerably since 2021, so ensure your records reflect your actual trading arrangements.

How long to keep records

HMRC’s rule is straightforward: keep VAT records for six years from the end of the quarter to which they relate. In practice, this means if you’ve claimed VAT in January to March of the current tax year, you must retain those records until 31 March six years later.

This applies to all records mentioned above—invoices, ledgers, bank statements, digital records, and supporting documentation. The six-year period exists partly to align with self-assessment record retention rules and partly to give HMRC adequate time to conduct investigations or audits.

If you’re subject to a VAT investigation or dispute, don’t destroy records until HMRC confirms the matter is closed. Similarly, if you’re involved in legal proceedings relating to your business, preserve relevant records beyond the six-year window until your advisers confirm it’s safe to do so.

Digital records and best practice

HMRC actively encourages digital record-keeping and, under Making Tax Digital rules, certain businesses must file VAT returns digitally using compatible software. Your records themselves don’t all need to be digital, but having electronic copies alongside physical originals is sensible.

Best practice tip: scan invoices and store them in an organised folder structure by date or supplier. Alongside your accounting software records, this creates a robust audit trail. Cloud storage adds another layer of security—your records survive office flooding or accidental deletion.

If you receive invoices by email, avoid deleting them from your inbox. Many accountants recommend exporting important emails to a dedicated folder or printing them for your paper records, depending on your preference and business volume.

Common compliance mistakes

Many businesses fall into the trap of discarding records once they’ve completed a VAT return, or keeping only a summary rather than the underlying invoices. HMRC can challenge your claims if you can’t produce the original supporting documents. Digital records created from paper originals are acceptable, but you need evidence of what the original said.

Another pitfall is failing to distinguish between personal and business expenses, then losing receipts. Keep everything clearly labelled, especially if you operate a home office or claim mileage allowance—these details matter during an inspection.
