The VAT Refund Hiding in Your Software Stack: A UK Small-Firm Checklist

If you run a limited company or a VAT-registered sole trader business in the UK, the 20% VAT on your software is usually not a real cost. It is a cash-flow item. You pay it, then you reclaim it. Yet plenty of small firms leave that money sitting with HMRC because the paperwork is wrong, the invoice never arrived, or nobody asked the supplier for a proper document.

This is not formal tax advice. Rules change, and partial exemption or mixed personal use can complicate things. But here is the practical checklist we would use before filing a software-heavy VAT return in 2026.

First, the boring bit: can you actually reclaim it?

You need to be VAT-registered. A sole trader below the registration threshold cannot reclaim VAT just because software is expensive. A limited company is in the same position: incorporation does not automatically make you VAT-registered. If you are registered, software bought wholly for business use is generally fair game. If you use a tool partly for personal work, apportion it honestly rather than claiming the lot.

If you are not registered but expect to cross the threshold soon, keep every software invoice anyway. You may be able to recover VAT on some purchases made before registration, depending on the rules and timing. Ask your accountant before assuming either way.

What a valid VAT invoice looks like, and what your card receipt is not

A card receipt is proof of payment. It is not normally a valid VAT invoice. A full VAT invoice should show the supplier's name, address and VAT number; a unique invoice number; the invoice date; your business name and address; a description of what was supplied; the net amount, VAT rate and VAT amount; and the total.

For software subscriptions, the invoice is often a PDF in your account area or an email attachment. Download it. Check that your VAT number is on it. If it is missing, update your billing details and ask the supplier to reissue the invoice. A monthly Stripe receipt with no VAT breakdown is not good enough for a tidy claim.

Overseas suppliers need care. If you buy digital services from a business outside the UK, the invoice may not show UK VAT. The reverse charge can apply: you account for VAT on your return and usually reclaim it in the same period. It sounds like extra admin for no gain, but it keeps your records straight and stops a future query becoming painful.

The bundle problem: hardware, software and the mysterious setup fee

Mixed purchases are where invoices get fuzzy. Buy a laptop with software preinstalled and the whole invoice may carry VAT. That is usually straightforward if the machine is for business use. Buy a 'software bundle' that includes setup, training or support and you may get one vague line item. Ask for a breakdown.

If a supplier sells hardware and software together, the invoice should still show the VAT charged on the whole supply unless a specific rule applies. Do not assume that because an item is described as software, it is outside VAT. Standard-rated is the norm for most commercial software. The mistake is not asking for an itemised invoice when the description says something like 'business system package' and nothing else.

Five mistakes that leave money on the table

• Using a card receipt or app store screenshot instead of a proper VAT invoice.
• Forgetting to add your VAT number to the software account, so every invoice is addressed to nobody in particular.
• Claiming the headline subscription but ignoring add-ons, extra seats, plugins and annual upgrade fees.
• Filing an overseas SaaS invoice without recording the reverse charge.
• Claiming VAT on tools that are partly for personal use and hoping nobody notices.

A simple quarterly routine

Once a quarter, open your software accounts and download every invoice as a PDF. Name the files clearly: supplier, month, invoice number. Drop them into a folder your accountant can access. Check the VAT number and the VAT amount before you file them. If something is missing, email the supplier that day. Most billing teams will reissue an invoice without argument.

Keep records for at least six years. If you use accounting software, attach the PDF to the transaction rather than relying on a note that says 'software'. Future you will be grateful.

When to ask for help

If you are partially exempt, buy software through a mix of business and personal accounts, or deal with overseas suppliers regularly, get your accountant involved. The point of this checklist is not to turn you into a VAT specialist. It is to stop obvious recoverable VAT from disappearing because the invoice was never requested.

Software is one of the easier business costs to document. A little housekeeping now can turn a stack of forgotten PDFs into a genuine refund.
