How Long to Keep Invoices in the UK: HMRC Rules Explained

Whether you're a sole trader or a limited company, understanding how long to keep invoices in the UK according to HMRC is important for compliance and financial health. In the UK, tax authorities require businesses to retain records for a specific period, and failing to do so can result in penalties.

HMRC requirements for invoice retention

The HMRC mandates different retention periods depending on your business type. For most businesses, the general rule is to keep records for six years. This applies to all records relating to VAT, Corporation Tax, and Income Tax.

Sole traders and partnerships

Sole traders and partnerships must keep their records for at least five years after the 31 January submission deadline of the relevant tax year. For example, if you submitted your 2022/23 tax return by 31 January 2024, you should keep your records until at least 31 January 2029.

Limited companies

Limited companies must keep records for six years from the end of the last company financial year they relate to, or longer if:

• they show a transaction that covers more than one accounting period
• the company has bought something expected to last more than six years, like equipment or machinery
• you sent your Company Tax Return late
• HMRC has started a compliance check into your Company Tax Return

VAT records

If your business is VAT registered, you must keep your VAT records and any supporting documents for six years. According to HMRC guidance, this includes all sales and purchase invoices, VAT credit notes, and debit notes. You can find more detailed guidance on VAT record-keeping on GOV.UK.

You might want to use a VAT calculator to ensure accuracy when dealing with VAT amounts on your invoices. This will not only help with record-keeping but also ensure you charge the correct VAT to your customers.

What records to keep beyond invoices

It's not just invoices you need to hold onto. HMRC expects you to keep a full picture of your business finances. For tradespeople, this typically means:

• Bank statements: Both business and personal if you mix the two (though you really shouldn't).
• Receipts for materials and tools: Every trip to the plumbers' merchant, electrical wholesaler, or builders' yard. These are your expense evidence.
• Mileage logs: If you claim vehicle expenses, keep a record of business miles driven. HMRC allows 45p per mile for the first 10,000 miles and 25p thereafter.
• Quotes and estimates you've issued: These help verify the scope and price of work if there's ever a dispute.
• Contracts and written agreements: Even informal email confirmations count.
• CIS payment and deduction statements: If you work under the Construction Industry Scheme, keep all verification and payment records. Use our CIS calculator to check deduction figures.

The general rule is: if it has a pound sign on it and relates to your business, keep it.

Practical tips for managing invoice records

Digital vs. physical storage

Both digital and paper records are acceptable to HMRC. However, digital records are easier to manage, search, and backup. Make sure any digital copies are accurate and legible. Consider using a free invoice generator to create compliant invoices quickly.

Organising your records

Organise your records by financial year and ensure they're easily accessible. Consider keeping a digital backup of all paper records and regularly updating your storage systems.

A practical filing system for tradespeople

Most tradespeople aren't office workers by nature — you'd rather be on site than sorting paperwork. So the best filing system is one that takes minimal effort to maintain.

Here's a simple digital setup that works:

Create a folder for each tax year (e.g., "2025-26"). Inside that, create subfolders for: Invoices Sent, Invoices Received, Bank Statements, Receipts, and Mileage.

Photograph receipts on the day you get them. Paper receipts fade, get wet in your van, and end up in the washing machine. Take a photo with your phone and drop it in the Receipts folder. Do this at the end of each day and it takes about two minutes.

Back everything up. Use a cloud service like Google Drive, Dropbox, or iCloud. If your phone gets nicked or your laptop dies, you haven't lost six years of records. HMRC won't accept "my dog ate my invoices" as an excuse.

If you're using InvoiceAdept to create and send your invoices, they're stored automatically in your account. That handles the "Invoices Sent" folder for you without any extra effort.

Making Tax Digital and record keeping

The government's Making Tax Digital (MTD) programme is changing how businesses keep and submit records. MTD for VAT is already in place for VAT-registered businesses. MTD for Income Tax Self Assessment is being rolled out from April 2026 for self-employed individuals and landlords with income over £50,000.

Under MTD, you'll need to keep digital records and submit quarterly updates to HMRC through compatible software. Paper records won't be enough on their own — you'll need a digital system that can talk to HMRC.

This is another reason to get your digital record-keeping sorted now rather than later. If you're still working from a shoebox of receipts and a handwritten invoice book, the transition will be painful. Starting with digital invoicing through a tool like our invoice generator is a straightforward first step.

If you're not sure whether you need to worry about MTD yet, check the current thresholds on gov.uk.

What happens during an HMRC enquiry

If HMRC decides to look into your tax affairs, they'll ask to see your records. This can happen at random — it doesn't mean you've done anything wrong. But if you can't produce the records they ask for, things get difficult quickly.

During an enquiry, HMRC may ask for:

• All invoices issued and received for the period under review
• Bank statements showing income and expenses
• Receipts for expenses you've claimed
• Mileage records if you've claimed vehicle costs
• Any contracts or agreements with clients

If your records are in order, the process is usually straightforward and can be handled by post or email. If they're not, HMRC may estimate your income — and they rarely estimate in your favour. They can also charge penalties for inadequate record-keeping, starting from £100 and going up to £3,000.

Having a clean, organised set of digital records makes an enquiry far less stressful. You can pull up any invoice, receipt, or bank statement within minutes rather than spending weeks digging through boxes. Our late payment calculator can also help you track any interest owed on overdue invoices, which HMRC may ask about if you've claimed bad debt relief.

Impact of failing to keep records

Failing to keep adequate records can result in hefty penalties from HMRC. You could face fines of up to £3,000 or even a tax bill based on estimated figures. It's important to stay compliant to avoid these costs.

Beyond the financial penalties, poor record-keeping creates practical problems. You can't accurately complete your Self Assessment if you don't know what you earned and spent. You might miss legitimate expense deductions that would reduce your tax bill. And if a client disputes a payment months down the line, you've got no evidence to fall back on.

If you work in construction and deal with CIS deductions, keeping records is even more important. You need to track CIS deductions made by contractors so you can offset them against your tax bill. Missing CIS records mean you could end up paying tax twice on the same income. Use our day rate calculator to make sure your pricing accounts for CIS deductions from the start.

FAQs

Do electronic invoices need to be kept in a specific format?

HMRC accepts digital invoices in any format, provided they are accurate and accessible. PDF, spreadsheet, or invoicing software exports are all fine. The key requirement is that they must be legible and you must be able to produce them if asked.

How should I report lost or stolen records?

If your records are lost or destroyed, inform HMRC immediately and try to recreate them as soon as possible. Contact your bank for duplicate statements, ask suppliers for copy invoices, and check your email for digital copies. Document your efforts to reconstruct the records.

What happens if I can't find specific invoices during an audit?

Inform HMRC and provide any available documents. Your tax return may be contested if sufficient evidence isn't provided, and HMRC may estimate your income based on available information — which typically results in a higher tax bill than your actual figures.

Could I be audited beyond the six-year period?

Generally, no, unless HMRC suspects fraud or deliberate tax avoidance, which can extend the period to 20 years. For careless errors (not deliberate), they can go back up to 6 years.

Can I destroy records after the required retention period?

Yes, once the required retention period passes, you may securely destroy your records. For paper records, use a shredder. For digital records, permanently delete them from all storage locations including cloud backups if you want to fully remove them.

Do I need to keep records of quotes that didn't lead to work?

Strictly speaking, no — HMRC only requires records of actual transactions. However, keeping quotes can be useful for your own business analysis and can help demonstrate your pricing methodology if HMRC questions your income levels.
