What Records Do I Need to Keep for VAT

Keeping proper VAT records is not just a formality. It is one of the core legal obligations that comes with being VAT registered and it is an area where HMRC shows very little flexibility. I regularly see businesses file VAT returns on time but still run into trouble because their underlying records are incomplete, inconsistent, or poorly organised.

In this article, I am going to explain exactly what VAT records you are required to keep in the UK, how long you must keep them for, and what HMRC expects to see if they ever review your VAT position. I will also explain how Making Tax Digital has changed record keeping, what digital records actually mean in practice, and the common mistakes I see businesses make.

Everything here reflects real UK practice and how the rules are applied by HMRC and published through GOV.UK, but explained in clear practical language rather than legislation.

Why VAT Record Keeping Matters

VAT is a transaction-based tax. HMRC is not just interested in the final VAT return figures. They care deeply about how those figures were arrived at.

If HMRC ever carries out a VAT inspection, they will not start by looking at your VAT return. They will start by looking at your records.

Good VAT records allow you to:

Support the figures on your VAT returns

Reclaim VAT correctly and confidently

Respond quickly to HMRC questions

Reduce the risk of penalties

Save time and stress

Poor records do the opposite.

The Legal Requirement to Keep VAT Records

If you are VAT registered, you are legally required to keep VAT records.

This applies whether you are:

A sole trader

A limited company

A partnership

A charity

A small business or a large one

There is no turnover exemption and no relaxation for small businesses.

How Long VAT Records Must Be Kept

In most cases, VAT records must be kept for at least six years.

This applies to:

Paper records

Digital records

Invoices

VAT returns

Supporting documents

There are limited situations where records may be kept for a shorter period, such as where HMRC has agreed to it or where records relate to goods with a shorter lifespan, but six years should be treated as the default.

HMRC can open enquiries into past VAT periods within this timeframe, so deleting records early is risky.

Core VAT Records You Must Keep

There are certain VAT records that every VAT registered business must keep, regardless of size or sector.

These form the backbone of your VAT compliance.

VAT Account

You must keep a VAT account.

This is not a bank account. It is a summary record that shows how you worked out the VAT figures on each VAT return.

Your VAT account should show:

Output VAT charged on sales

Input VAT reclaimed on purchases

Any adjustments made

The net VAT payable or reclaimable

Most accounting software maintains this automatically, but if you are using spreadsheets, you must ensure this information is clearly recorded.

Sales Records

You must keep records of all sales made by the business.

This includes:

VAT invoices issued

Sales receipts

Till reports

Online sales records

Marketplace sales reports

Sales records must show:

The date of sale

The value of the sale

The VAT rate applied

The VAT amount charged

This applies to standard rated, reduced rate, and zero rated sales.

Even zero rated sales must be recorded because they count towards VAT turnover.

Purchase Records

You must keep records of all purchases and expenses.

This includes:

Supplier VAT invoices

Receipts

Import VAT documentation

Expense claims

Purchase records must show:

The supplier’s name and VAT number

The date

The net amount

The VAT amount

The total amount paid

Without a valid VAT invoice, VAT cannot usually be reclaimed.

VAT Invoices and What They Must Show

VAT invoices are a key part of VAT record keeping.

If you issue VAT invoices, they must contain specific information.

A full VAT invoice must include:

Your business name and address

Your VAT registration number

A unique invoice number

The invoice date

The tax point if different

The customer’s name and address

A description of the goods or services

The net amount

The VAT rate applied

The VAT amount

The total gross amount

If you reclaim VAT, you must also hold VAT invoices from your suppliers that meet similar requirements.

Simplified VAT Invoices

For sales of £250 or less including VAT, simplified VAT invoices are allowed.

These must show:

Your business name and VAT number

The date

The total amount including VAT

The VAT rate

These are common in retail and hospitality businesses.

Records of VAT Exempt and Zero Rated Supplies

It is not enough to keep records only for VAT charged at 20 percent.

You must also keep records of:

Zero rated supplies

VAT exempt supplies

HMRC expects clear separation between taxable and exempt income, especially where partial exemption applies.

Import and Export VAT Records

If you import or export goods, additional records are required.

Import VAT Records

You must keep:

Postponed import VAT statements

C79 import VAT certificates where VAT was paid upfront

Customs declarations

Freight and courier documentation

These records support any import VAT reclaimed or declared.

Export Records

If you zero rate exports, you must keep evidence that goods left the UK.

This can include:

Shipping documents

Bills of lading

Courier confirmations

Export declarations

Without proof of export, HMRC may disallow zero rating.

Records for VAT Schemes

If you use a VAT scheme, you must keep additional records specific to that scheme.

Flat Rate Scheme

You must keep records of:

Gross turnover

Flat rate percentage applied

VAT calculations

Cash Accounting Scheme

You must keep records of:

Payments received

Payments made

Dates of payment

VAT is accounted for based on cash movement rather than invoices.

Annual Accounting Scheme

You must keep records supporting:

Instalment calculations

Final annual VAT return

Making Tax Digital and VAT Records

Making Tax Digital has changed how VAT records must be kept.

Under Making Tax Digital:

VAT records must be kept digitally

VAT returns must be submitted using compatible software

Digital links must exist between records and returns

This does not necessarily mean everything must be paperless, but the key VAT data must exist in digital form.

What Counts as a Digital Record

A digital VAT record includes:

Date of supply

Value excluding VAT

VAT rate applied

This information must be stored electronically.

Scanned invoices, accounting software, and spreadsheets can all qualify, provided they meet the requirements and are digitally linked.

Digital Links Explained Simply

A digital link means data flows between systems without manual retyping.

For example:

A spreadsheet linked to accounting software

Accounting software linked to VAT submission software

Copying and pasting figures manually breaks the digital link and is not compliant long term.

Adjustments and Supporting Records

If you make adjustments on your VAT return, you must keep records explaining them.

This includes:

Partial exemption calculations

Bad debt relief claims

Capital goods scheme adjustments

Error corrections

VAT on fuel scale charges

HMRC expects to see not just the adjustment but the reasoning behind it.

Records for Business Assets

You must keep VAT records relating to assets, including:

Purchase invoices

VAT reclaimed

Disposal records

VAT charged on sale or deregistration

These records become particularly important if you later deregister for VAT.

Records for Deregistration and Final VAT Returns

When you deregister for VAT, you must keep:

The final VAT return

Stock valuations

Asset valuations

Correspondence with HMRC

VAT on assets and stock is one of the most common areas HMRC challenges after deregistration.

Marketplace and Online Sales Records

If you sell online, HMRC expects you to retain:

Amazon or eBay sales reports

Records showing VAT collected by marketplaces

Fee invoices and VAT treatment

Evidence supporting VAT returns

HMRC receives data directly from marketplaces, so your records should reconcile to what HMRC can already see.

What Happens If Records Are Missing or Poor

If HMRC inspects your VAT records and finds gaps, they can:

Disallow VAT reclaims

Estimate VAT due

Apply penalties

Extend assessment periods

Open wider compliance checks

Even where VAT returns were filed correctly, poor records can still lead to assessments.

Penalties for Poor VAT Record Keeping

HMRC penalties are based on behaviour.

Poor record keeping can be classed as:

Careless

Deliberate

Concealed

The worse the record keeping, the higher the potential penalties.

Good records are one of the strongest protections you have.

Common VAT Record Keeping Mistakes I See

In practice, the same issues come up repeatedly:

Missing VAT invoices

Reclaiming VAT on receipts without supplier VAT numbers

No separation of VAT rates

Manual retyping of figures

Missing import VAT statements

Deleting old records too early

Relying on bank statements alone

Most of these mistakes are easy to avoid with the right systems.

Practical Tips for Keeping VAT Records Properly

In practical terms, I recommend:

Using accounting software from the outset

Uploading invoices regularly

Downloading HMRC statements monthly

Keeping clear folders for VAT periods

Reviewing VAT reports before submission

Retaining records for at least six years

Consistency matters more than complexity.

HMRC Inspections and What They Ask For

If HMRC carries out a VAT inspection, they will usually ask for:

VAT returns

Sales and purchase ledgers

VAT invoices

Import VAT evidence

Explanations of adjustments

If these are readily available and well organised, inspections are usually straightforward.

When I Recommend Professional Help

I strongly recommend advice if:

You have mixed VAT supplies

You are partially exempt

You import goods

You sell online or internationally

HMRC has raised questions previously

VAT record keeping becomes more complex as businesses grow.

Practical Summary

In practical terms, you must keep:

A VAT account

Sales and purchase records

VAT invoices

Import and export documentation

Adjustment workings

Digital records under Making Tax Digital

Records for at least six years

Good VAT records are not optional. They are the foundation of VAT compliance.

Final Thoughts

VAT record keeping is not about bureaucracy for its own sake. It is about being able to explain and support your VAT position with confidence. HMRC does not expect perfection, but they do expect clarity, consistency, and evidence.

My advice is always to treat VAT records as part of running a professional business rather than an afterthought. The time spent keeping them properly is far less than the time and cost of fixing problems later.
