Making Tax Digital Vat

You've opened the VAT return spreadsheet, checked the totals twice, and now you're wondering whether copying those figures into a filing tool is still acceptable. For a UK VAT-registered business, that uncertainty is a compliance problem, not a software preference. Making Tax Digital for VAT is now the normal VAT system, and the right response is to build a reliable working process around it.

The key question isn't, “Which software should I buy?” It's whether your records flow cleanly from transactions to VAT return, whether the submission reaches HMRC through the approved route, and whether you can identify and correct errors before they become expensive. The choices you make now also matter for Making Tax Digital for Income Tax from April 2026, particularly if you're a sole trader or landlord.

What Making Tax Digital for VAT Actually Means in 2026

Making Tax Digital for VAT applies to every VAT-registered business in the UK, unless HMRC has granted a valid exemption. The rules require you to keep VAT records digitally and submit VAT returns through MTD-compatible software, rather than typing figures into the old HMRC online portal. HMRC's Making Tax Digital for VAT guidance confirms that the regime has applied to all VAT-registered businesses since April 2022.

That means your accounting system must do more than store invoices. It needs to calculate the VAT return, preserve the connection between your source records and reported figures, communicate with HMRC through an API, and retain evidence of the submission. An API is the secure software connection that allows your accounting system to exchange information with HMRC.

The practical change for your business

You can't treat VAT filing as a quarterly exercise where someone gathers totals from different places and manually re-enters them into a government webpage. The VAT portal closed on 1 November 2022, so the current route is software-led submission through the HMRC API, as set out in the official VAT notice.

A compliant MTD VAT system has four working parts:

• Software selection: Choose a product that HMRC recognises and that suits your bookkeeping needs.
• Digital link setup: Make sure figures move electronically between systems without manual re-keying.
• Submission workflow: Retrieve the obligation, review the return, submit through the software, and store the confirmation.
• Error control: Reconcile the return before filing and follow a clear process when you find a mistake.

Practical rule: If your software produces the VAT figures but you manually type them into another filing tool, stop and document the process. You may have broken the digital link.

MTD for VAT isn't a one-off technology project. It's a recurring control system that should operate every month, not just on the filing day.

Who Is in Scope and Why the Deadlines Matter

The scope is straightforward. Every VAT-registered business is in MTD for VAT, regardless of turnover, unless HMRC accepts an exemption. That includes limited companies, sole traders, partnerships, landlords with VAT registration, VAT groups and businesses using special VAT arrangements. Businesses in insolvency procedures may fall outside the normal digital requirement, and HMRC can consider limited digital exemptions where using computers, software or the internet isn't practical.

The rollout happened in stages. From April 2019, MTD for VAT applied to VAT-registered businesses with taxable turnover above the £85,000 VAT threshold, according to HMRC's final evaluation of Making Tax Digital for VAT. Certain complex organisations received a deferral until October 2019. From April 2022, the regime expanded to all VAT-registered businesses, regardless of turnover.

April 2022 is the date that matters

The earlier dates explain the history, but April 2022 is the practical compliance anchor for SMEs. If you're VAT-registered today and still maintain your VAT records in an isolated spreadsheet, or use desktop software that can't connect to HMRC, your process doesn't meet the standard route. The fact that your business joined the VAT register recently, or that your turnover sits below the former threshold, doesn't change that.

The online VAT portal is no longer the normal filing channel. Your business, or your authorised accountant, must use compatible software to send the return. HMRC allows exemptions only in limited circumstances, and you should wait for HMRC's decision before relying on an alternative filing method.

Check your own position

Start with three facts:

1. Your VAT registration status: If you're VAT-registered, assume MTD applies.
2. Your registration history: Businesses that registered before April 2022 may already have changed systems, but the obligation now applies equally across the VAT population.
3. Your software route: Confirm that your product appears on HMRC's published list of compatible software, or that your spreadsheet connects through an approved bridging product.

The next decision is broader than VAT. HMRC says MTD for Income Tax starts from April 2026 for sole traders and landlords with qualifying income above £50,000, and its technical note reports that more than 570,000 taxpayers had signed up by its 2026 update. That makes software choice a business systems decision, not merely a VAT filing decision.

Choosing MTD-Compatible Software That Fits Your Business

Don't choose software because the interface looks attractive or because the monthly price is low. Choose it based on how your business records transactions, reconciles bank activity, manages users and will handle future tax obligations.

Most SMEs will consider one of three routes:

Full cloud accounting is the default recommendation

For most SMEs, use a full cloud platform such as Xero, QuickBooks or Sage. These systems can combine sales invoices, purchase bills, bank feeds, nominal coding, VAT reports and submission activity. Xero is a common SME choice because it supports MTD submission, bank feeds and a broader cloud bookkeeping workflow, while its product ecosystem can support preparation for Income Tax requirements from 2026.

A specialist platform can be the right answer where stock, construction work, property activity or another sector-specific process drives the accounting. Don't assume specialist software is compliant because it produces a VAT report. Check how the VAT figures reach HMRC and whether the underlying records remain digitally linked.

Bridging software has a legitimate place. It can connect a spreadsheet or older system to HMRC, but it shouldn't become an excuse to preserve a fragile process indefinitely. If staff calculate VAT in one workbook, make adjustments in another and submit through a third tool, your control environment is asking for trouble.

For broader context on system selection and finance IT from F1Group, look beyond tax filing and assess how the finance system supports access, security, reporting and integration.

Use this buying checklist

Before committing, confirm that the product:

• Appears on HMRC's compatible software list: Don't rely on a reseller's general claim.
• Supports API submission: You need a live connection to HMRC, not just VAT calculations.
• Offers appropriate user access: Your bookkeeper, accountant and management team may need different permissions.
• Provides meaningful bank reconciliation: Imported transactions still need review and correct coding.
• Has a credible Income Tax roadmap: If you're a sole trader or landlord, check its MTD Income Tax capability before you migrate.

Digital Record Keeping and the Digital Link Explained

Digital record keeping means more than saving a PDF of each invoice. Your accounting records must contain enough information to support the VAT return and allow an auditor or HMRC officer to follow the calculation back to the underlying transaction.

For each relevant transaction, your records should capture the time of supply, value, VAT amount, VAT rate, VAT category, supplier or customer details, description, invoice reference and invoice date. The exact treatment depends on your transaction and VAT scheme, but the central principle is consistent: each reported figure needs a traceable source.

Build a chain from invoice to return

Think of the digital link as a chain:

1. A sales invoice or purchase bill is created or received.
2. The transaction enters your accounting system through direct entry, an electronic transfer, email capture or a structured export.
3. The system applies the correct VAT treatment and posts the transaction to the ledger.
4. The VAT report draws its boxes from that ledger.
5. The software sends the return to HMRC through the API.

The weak point is usually manual re-entry. Copying a total from a spreadsheet into a VAT return tool may produce the right number, but it interrupts the electronic audit trail. HMRC's VAT digital record guidance requires businesses to maintain the digital link through the VAT calculation and submission process.

If your business has a bespoke system, you don't necessarily need to replace it immediately. A functional compatible software setup can connect older records to a compliant filing product, provided you can explain how the data moves and demonstrate that the return figures came from the digital records.

What evidence should you retain?

Keep the source invoices, transaction exports, reconciliation reports, adjustment notes and submission confirmation. Your evidence should show who prepared the return, who reviewed it, how unusual items were treated and how the final figures reconcile to the ledger.

For a practical review of the underlying process, use this guide to VAT digital record keeping.

The following video provides an additional visual explanation of the workflow. Watch it after reviewing your own data path, because the useful question is whether your system behaves in the same way.

Submitting Your VAT Return Through HMRC-Approved Software

The submission process should be routine. If your bookkeeping is current and your VAT codes are configured correctly, filing becomes the final controlled step rather than a last-minute reconstruction of the quarter.

A sensible workflow looks like this:

Retrieve the obligation first

Open your MTD-compatible software and connect it to HMRC using the correct business credentials or agent authority. The software should retrieve the VAT obligation, including the accounting period and filing deadline. Don't begin by typing dates from memory. The obligation retrieved from HMRC is the reference point for the return.

Reconcile before you submit

Review the VAT report against the underlying records. At minimum, reconcile:

• sales and purchase ledger totals,
• output VAT and input VAT,
• VAT control account movements,
• unusual transactions and manual journals,
• the return boxes against the trial balance or management accounts.

Investigate differences before submitting. A return can be technically accepted even when the accounting behind it is incomplete, so the software connection doesn't replace professional judgement.

Lock the period and send

Once the review is complete, lock the VAT period in your accounting system or otherwise prevent untracked edits. Submit the return from the software, not from the old HMRC portal. HMRC expects the compatible system to retrieve obligations, send the return through the API and return an Accepted status when the submission has been received successfully, as explained in technical software guidance on MTD VAT submissions.

Save the confirmation, submission reference and final VAT report in your records. Your accountant may submit on your behalf, but you remain responsible for giving them complete records and agreed approval authority.

If you need a more detailed operational checklist, follow this guide on how to submit VAT returns. Corrections should also follow the current HMRC reporting process. Don't rely on the old VAT652 form route without checking the applicable method in your software and HMRC guidance.

Common Pitfalls, Error Thresholds and How to Avoid Penalties

The most dangerous MTD mistake is believing that a correct total is enough. It isn't. HMRC's rules focus on the integrity of the digital records and the submission route as well as the VAT amount.

Manual copying is the first failure point. If your team calculates VAT in a spreadsheet and re-keys totals into a filing product, the process may lack the required digital link. A bridging tool can be suitable where it transfers the relevant data electronically, but you need a documented explanation of how the figures move from source records into the return.

Late filing is the second. Build the review into your monthly bookkeeping routine instead of waiting until the VAT deadline. HMRC's points-based system can award a penalty point for a late submission, and a fixed £200 penalty applies once the business reaches its filing-frequency threshold, according to the HMRC VAT guidance.

Use the error thresholds as a control rule

HMRC provides a practical benchmark for correcting VAT errors:

• Errors up to £10,000 can usually be adjusted on the next VAT return.
• Errors between £10,000 and £50,000 can usually be adjusted on the next return only where they're below 1% of box 6 turnover.
• Larger errors must be reported directly to HMRC.

These thresholds come from HMRC's error-correction framework, summarised in VAT error reporting guidance. Your internal procedure should record the error, quantify it, identify the affected period, decide whether self-correction is allowed and escalate where necessary.

Make the controls boring

Run a pre-submission review every quarter. Reconcile the VAT return to the ledger, review unusual tax codes, check that the period is complete and retain the evidence. If you can't pay the VAT, file on time and contact HMRC about payment. Don't delay the return because payment is difficult.

Control that works: Separate preparation, review and submission where your team size allows it. A second pair of eyes catches coding mistakes that software can't understand.

Bridging VAT and Income Tax and When to Bring in an Accountant

VAT bookkeeping is already the foundation for a wider digital tax workflow. From April 2026, MTD for Income Tax starts for sole traders and landlords with qualifying income over £50,000, according to HMRC's technical note on modernising the tax system. HMRC's update also records more than 570,000 taxpayers signed up for MTD for Income Tax, so this isn't a distant administrative theory for affected businesses.

The mistake is to run VAT and Income Tax as completely separate bookkeeping projects. If your sales, expenses and bank activity are fragmented across spreadsheets, desktop records and cloud software, you'll create duplicate work when the Income Tax process requires digital updates.

Design one finance workflow

Use one nominal chart of accounts where possible. Reconcile the bank regularly, capture invoices digitally and keep business and personal transactions clearly separated. Then check whether your VAT software also supports MTD for Income Tax, rather than assuming that a product capable of VAT submission automatically handles every Income Tax requirement.

A practical setup should answer these questions:

• Where are transactions entered? Pick one primary ledger.
• Who reviews the coding? Assign responsibility before the quarter ends.
• How are adjustments recorded? Keep an audit trail for journals and corrections.
• Can the system support both taxes? Confirm the product's 2026 Income Tax functionality directly with the provider.
• What does the accountant receive? Agree the reports, exports and access rights in advance.

Cloud platforms such as Xero and QuickBooks are obvious products to assess, but functionality varies across providers and packages. Don't sign a long contract until you've checked the specific MTD Income Tax features your business needs.

Know when software isn't enough

You may be able to manage the system yourself if you have straightforward transactions, stable margins, no partial exemption issues and enough time to reconcile records consistently. Bring in an accountant where you deal with partial exemption, cross-border VAT, annual accounting scheme changes, complicated adjustments, multiple income streams, MTD Income Tax submissions or an HMRC enquiry.

A sensible 12-month plan is:

1. Review the current VAT software and registration details.
2. Map every transaction route into the VAT return.
3. Replace manual re-entry with a documented digital link.
4. Test the software's Income Tax capability if you may be in scope.
5. Start monthly reconciliations and quarterly review habits.
6. Agree with an accountant who prepares, reviews and submits each obligation.

MTD works when the process runs continuously. Review your software and VAT workflow before the next return, then arrange a structured readiness meeting with Stewart Accounting Services or another qualified adviser if you're unsure whether your records, digital links or future Income Tax setup meet HMRC's requirements.
