A Guide to Making Tax Digital (MTD) for VAT in the UK

Making Tax Digital (MTD) for VAT means VAT-registered businesses must keep the required VAT records digitally and submit VAT Returns through compatible software, unless HMRC has accepted that they are exempt. It is not just an online form. The change affects how you capture sales, expenses and VAT figures throughout the quarter.

The practical answer is to use a reliable accounting system, keep records up to date and make sure the person submitting the return can see the right information. Once the process is in place, MTD can reduce rekeying and make your VAT position easier to monitor. For many businesses in Cheltenham, Gloucestershire and across the UK, it is also a good reason to improve everyday bookkeeping.

Who needs to follow MTD for VAT?

All VAT-registered businesses should now be signed up for Making Tax Digital for VAT. GOV.UK confirms this in its current VAT charging, reclaiming and record-keeping guidance. There are limited exemptions, for example where it is not reasonably practical for a business to use digital tools, but you should not assume an exemption applies without discussing it with HMRC.

MTD applies whether you are:

• A sole trader. Your VAT records can sit alongside your Self Assessment bookkeeping, but the VAT process still needs to meet the MTD requirements.
• A limited company. The company needs clear records of its VAT sales and purchases, as well as the information needed for its accounts and Corporation Tax return.
• A partnership or other business. The digital record and software rules apply to the registered entity.
• Voluntarily registered. The requirement is not limited to businesses above the compulsory registration threshold.

What MTD actually requires

There are two connected requirements: keeping the prescribed records digitally and filing the VAT Return through functional compatible software. You can use accounting software, a spreadsheet linked to bridging software, or another system that meets HMRC’s requirements. Copying figures manually from a spreadsheet into the old VAT portal is not the intended process.

In everyday terms, your system needs to keep a digital record of the VAT data behind your return and send the figures to HMRC digitally. The software should give you a clear audit trail from the transaction to the VAT Return.

What a digital link means in practice

A digital link is an electronic transfer or exchange of data between pieces of software or between a spreadsheet and compatible filing software. It is there to preserve the trail from the underlying record to the submitted return. Re-typing totals into another spreadsheet or manually keying the nine VAT-box figures into a portal is not the same thing.

You do not need to make the process complicated. The aim is simply to avoid breaking the chain of evidence. Choose a system that keeps the records, calculations and final submission connected in a way that someone else could follow.

Part of the process	What good practice looks like
Sales invoices	Create invoices through your system or record each sale promptly with the correct VAT treatment.
Purchase invoices	Keep supplier invoices and receipts, capture the VAT amount and record the correct expense category.
VAT treatment	Use the right VAT rate and identify reverse charge, exempt, zero-rated or out-of-scope items where relevant.
Quarter-end review	Reconcile the bank, check the VAT control account and review unusual transactions before filing.
Submission	File from compatible software and retain the confirmation and a copy of the submitted return.

Why spreadsheets alone can create problems

A spreadsheet is not automatically wrong. Some businesses use one successfully, especially where the transaction volume is low. The problem arises when the spreadsheet is incomplete, formulas are changed accidentally, records are typed twice or the VAT figures are copied manually into different systems.

Cloud accounting software can make the process easier by bringing bank transactions, invoices, receipt images and VAT reports into one place. It also gives your accountant access to the same live information, which means queries can be resolved before the filing deadline instead of after it. Focus on choosing a system that your business will actually keep up to date.

Records you should have before filing

A VAT Return is only as good as the records behind it. Before each submission, make sure you can explain how the figures have been produced.

• Sales are complete. Check that invoices, cash sales, online platform income and credit notes are all included in the correct period.
• Purchases have evidence. Keep VAT invoices where input VAT is being reclaimed and make sure personal expenditure is not included.
• The bank is reconciled. Every bank transaction should be matched or investigated. Unreconciled bank feeds are a common source of missing income and duplicated costs.
• VAT codes make sense. Look for unusual codes, zero VAT on a standard-rated cost, or VAT reclaimed where the invoice does not support it.
• Special transactions are reviewed. Overseas purchases, reverse charge services, deposits, deposits and partially exempt activities often need more than a quick automated rule.

It is useful to separate the deadline for submitting the VAT Return from the deadline for paying the VAT. Your online VAT account can show due dates, payments and any amounts outstanding; GOV.UK explains the features of the VAT online account.

Common MTD VAT mistakes

Most VAT errors are process errors rather than deliberate ones. They build up when the bookkeeping is left until the end of the quarter.

• Using the wrong VAT rate. Standard, reduced, zero-rated and exempt supplies are not interchangeable. Check the treatment before raising an invoice or reclaiming VAT.
• Claiming VAT on unsupported costs. You usually need proper evidence. A bank statement showing a payment is not always enough to support the input VAT claim.
• Mixing personal and business spending. This makes the VAT return harder to review and can create director’s loan or benefit issues for a company.
• Ignoring credit notes. A credit note affects the VAT position and needs to be recorded in the correct period.
• Leaving it too late. Last-minute filing gives you little time to investigate a large or unexpected liability.

How to make VAT less stressful

The strongest VAT process is usually simple and regular. Set aside a short time each week to raise invoices, upload receipts and reconcile the bank. Then complete a proper review shortly after the quarter end, while transactions are still familiar.

A good workflow might look like this:

1. Raise invoices promptly. This improves cash collection and keeps sales records current.
2. Capture bills as they arrive. Do not rely on a pile of paper or an inbox search three months later.
3. Reconcile weekly or monthly. Match the bank feed and investigate transactions that do not belong.
4. Review the VAT report. Compare it with the previous quarter and ask why the figures have moved.
5. File and save confirmation. Submit via the approved software and retain the records that support the return.

That routine will also make your annual accounts and tax planning easier. VAT bookkeeping is not separate from the rest of the business; it is part of the same financial picture.

Do not overlook the wider digital picture

VAT MTD is often the first digital tax process a business experiences, but it should not be treated as a one-off compliance project. A well-organised accounting system can help you see who owes you money, what you owe suppliers, how much VAT may be due and whether the business is generating enough cash.

If you are a sole trader, that better information is also useful when considering whether a company structure is right for you. Read our guide on when a sole trader may move to a limited company for the broader decision.
