MTD for VAT is mandatory for all UK VAT-registered businesses, and you must use compatible software to keep required digital records and submit returns. HMRC signs up new registrants automatically once they register for VAT. Your immediate priorities are checking your software is compatible, authorising your agent if you use one, and confirming your next filing deadline before it arrives.
TL;DR:
- Compatibility testing is crucial; run a test export from your main system and ensure no manual intervention is needed before your first VAT return.
- Digital links between systems must be automated via API, XML, or CSV; manual copy-pasting breaks the digital journey and can lead to penalties.
- Authorise your agent early through the digital handshake, and allow at least 72 hours for processing before the return deadline to avoid missed filings.
- Late submissions now accrue points, with fixed penalties once thresholds are reached, and record-keeping errors can result in daily fines up to £15 per day.
- Exemptions are rare and require evidence; most businesses need compliant software and proper setup, with continuous testing especially after adding new systems.

What MTD for VAT requires: electronic accounts and digital links
Under VAT Notice 700/22, every VAT-registered business must keep an “electronic account”. This is not a single piece of software but a structured digital record of specific data, held in a format HMRC’s systems can read and submit from directly.
The records that must be kept digitally include:
- Your business name, VAT registration number and address (designatory data).
- The VAT account itself, including output tax and input tax figures for each period.
- Details of every supply made and received, with date, value and VAT rate.
- Totals for adjustments such as bad debt relief or partial exemption calculations.
Source documents, invoices, receipts and paper records, do not need to be scanned or stored digitally. The requirement is that the transactional data behind them sits in your electronic account, not the paper itself.
Crucially, that account can span more than one product. You might record sales in one system and run payroll in another, provided the two are joined by a compliant digital link rather than by re-entering figures by hand. HMRC’s guidance is explicit that the electronic account can be built from multiple linked tools, which is useful for ecommerce sellers juggling marketplace exports, spreadsheets and accounting software.
What counts as compatible software and which links are acceptable
“Functional compatible software” means any product, or combination of products, that can record and preserve digital records, connect to HMRC’s systems via API and receive information from HMRC. There is no single approved product: HMRC maintains a directory of software that meets these criteria, and many businesses use more than one tool together.
The links between those tools matter as much as the tools themselves. Acceptable digital links include:
- API connections that pass data automatically between systems.
- XML or CSV file imports and exports moved without manual editing.
- Bridging software that reads data from a spreadsheet and submits it to HMRC.
What is not acceptable is copying and pasting, or manually retyping, figures from one system into another once those figures form part of your VAT records. HMRC’s compliance guidance treats this as breaking the “digital journey” the rules are built around.
Before your first submission, run a test: export data from your main system, pass it through any bridging or linking tool, and confirm the figures match with no manual intervention required.
Pro Tip: Keep a simple map of every system that touches your VAT figures and how they connect. It’s the fastest way to spot a manual step hiding in your process.
Signing up, agent authorisation and getting the timing right
HMRC signs new VAT registrants up to MTD automatically, but automatic enrolment does not mean automatic compliance. You still need compatible software in place before your first return is due, and if an accountant files on your behalf, they need to be properly authorised first.
- Confirm your VAT registration status and check which return period applies to you.
- If you use an agent, they should hold an agent services account and request authorisation through the “digital handshake” rather than an older-style authorisation.
- Approve that authorisation request promptly through your business tax account.
- Allow enough time before your return is due: HMRC’s agent guidance recommends at least 72 hours for non-Direct Debit payers, or seven working days where Direct Debit is involved.
- Test the submission route once authorisation is confirmed, rather than waiting until deadline week.
Leaving sign-up or authorisation until the days before a return is due is one of the most common causes of missed deadlines, particularly for businesses that have just registered for VAT.
Penalties and deadlines you need to plan around
Since 1 January 2023, late VAT returns are penalised through a points-based system rather than an automatic fine on every late filing. You gain a point each time you miss a submission deadline, and once you hit the threshold for your filing frequency, a £200 fixed penalty applies, with a further £200 for each subsequent late return while you remain at the threshold, as set out by HMRC.
- Annual filers reach a fixed penalty threshold after a small number of late submissions.
- Quarterly filers reach a fixed penalty threshold after multiple late submissions.
- Monthly filers reach a fixed penalty threshold after several late submissions.
Separately, HMRC’s compliance guidance sets out daily penalties of roughly £5 to £15 for failing to keep digital records or maintain proper digital links, and a penalty of up to £400 per return for filing without functional compatible software.
The most reliable mitigation is procedural: use your software’s built-in checking functions before submitting, fix errors as soon as you spot them rather than at year end, and keep a downloaded copy of every return you submit as evidence of what was filed and when.
Exemptions and where to get official help
Exemption from MTD for VAT is granted narrowly, and HMRC assesses each case on its own facts rather than by category. Typical grounds include:
- Genuine digital impracticability, for example due to age, disability, remoteness of location or a religious objection to using computers.
- Insolvency, where a business is subject to an insolvency procedure.
- Cases where HMRC is satisfied that it is not reasonably practicable for the business to use digital tools for reasons beyond its control.
If you believe you qualify, you apply directly to HMRC rather than simply opting out, and you should expect to provide evidence supporting your circumstances. Businesses that do not qualify but want to move early, or that need to confirm their obligations, can use the VAT Helpline or the guidance pages on GOV.UK for current forms and instructions, since exemption criteria and application routes are reviewed periodically.
A 30 day compliance checklist for getting MTD right
- Confirm your VAT registration and current filing frequency.
- Check your software against HMRC’s compatible software list.
- Map every digital link between systems and remove any manual transfer step.
- Authorise your agent through the digital handshake if one files on your behalf.
- Run a test submission well before your actual deadline.
- Switch on your software’s error-checking functions as standard practice.
- Put a quarterly review in the diary to catch drift before it becomes a penalty.
Ongoing client support includes managing Xero integration and digital links, handling agent authorisation, and reviewing VAT returns before submission rather than after a problem appears. The most common pitfall is treating MTD as a one-off setup rather than a system that needs occasional checking, especially when a business adds a new sales channel or piece of software.
Pro Tip: Re-run your digital link check whenever you add a new sales channel or accounting tool, not just once a year.
Why accountants should treat MTD as a systems project
MTD moved VAT compliance risk out of the filing cabinet and into your processes. The businesses that struggle are rarely the ones that misunderstand VAT: they are the ones with an undocumented manual step buried between two systems.
Treat every digital link as something to document and re-test, not something you set up once and forget. That habit does more to prevent penalties than any last-minute check before a deadline.

FAQ
Does MTD apply to VAT for every registered business?
Yes, MTD for VAT applies to all VAT-registered businesses in the UK, with exemption granted only in narrow, individually assessed circumstances. Full detail on record-keeping and software requirements sits in VAT Notice 700/22.
How do I set up MTD for VAT as a new registrant?
HMRC automatically signs up new VAT registrants to MTD, but you still need functional compatible software in place before your first return is due. Check the software list, set up any digital links between systems, and authorise your agent through the digital handshake if one files on your behalf.
Can I submit a VAT return without using MTD software?
No, VAT-registered businesses must submit returns through compatible software connected to HMRC’s systems rather than by manual entry on the old portal. Filing without functional compatible software can attract a penalty of up to £400 per return under HMRC’s compliance guidance.
What happens if I miss the MTD VAT deadline?
Missing a submission deadline earns you a point under HMRC’s points-based penalty system, and reaching your threshold triggers a £200 fixed penalty, as set out in HMRC’s penalty points guidance. The threshold is 2 points for annual filers, 4 for quarterly filers and 5 for monthly filers.
