Making Tax Digital (MTD) is transforming how UK businesses maintain financial records and submit tax information to HMRC. It replaces manual processes with a more accurate, efficient and digitally connected tax-reporting system.

This guide explains the essential MTD compliance requirements, including digital record-keeping, compatible accounting software and electronic submissions to HMRC.

What Is Making Tax Digital?

Making Tax Digital is an HMRC initiative designed to simplify tax administration for individuals and businesses. Under the programme, eligible businesses are required to:

Maintain accurate digital financial records using compatible software.
Submit tax information directly to HMRC through MTD-compatible software.
Preserve digital links when transferring data between different software products.

MTD for VAT: Essential Requirements

Who Must Follow MTD for VAT?

Making Tax Digital for VAT applies to all VAT-registered businesses, including those that registered voluntarily. New VAT-registered businesses are generally enrolled automatically by HMRC.

Businesses that cannot reasonably use digital tools because of age, disability, location, religious beliefs or another valid reason may apply to HMRC for an exemption.

Digital Records You Must Maintain

Your MTD-compatible system should retain essential VAT information, including:

Business name, address and VAT registration number
Time and value of each supply, excluding VAT
Applicable VAT rate for each transaction
VAT charged on sales and VAT paid on purchases
Adjustments included within VAT returns
Reverse-charge transactions, where applicable
Information required for any VAT accounting schemes used

MTD-Compatible Software Requirements

Businesses must use compatible accounting software or suitable bridging software to:

Create, store and preserve digital VAT records
Prepare VAT returns using information from those records
Submit VAT returns directly to HMRC
Receive information from HMRC
Maintain digital links when transferring data between software systems

MTD for Income Tax: Current Requirements and Rollout

Who Must Use MTD for Income Tax?

Making Tax Digital for Income Tax applies to eligible sole traders and landlords based on their total qualifying income from self-employment and property:

From 6 April 2026: Qualifying income over £50,000
From 6 April 2027: Qualifying income over £30,000
From 6 April 2028: Qualifying income over £20,000
Voluntary participation: Eligible individuals may join before they are legally required to do so

Qualifying income means total gross income from self-employment and property before expenses and tax deductions.

Digital Reporting Requirements

Under MTD for Income Tax, eligible sole traders and landlords must use compatible software to:

Create and maintain digital records of business and property income and expenses
Send quarterly summaries to HMRC
Review and correct their information after the fourth quarterly update
Submit their Self Assessment tax return through compatible software
Pay the tax due by 31 January following the end of the relevant tax year

The existing references to an End of Period Statement (EOPS) and final declaration should be removed and replaced with submitting a tax return.

Standard Quarterly Update Deadlines

Quarterly update	Cumulative period covered	Submission deadline
Q1	6 April to 5 July	7 August
Q2	6 April to 5 October	7 November
Q3	6 April to 5 January	7 February
Q4	6 April to 5 April	7 May of the following tax year

Each update contains cumulative totals from the beginning of the tax year—not only the transactions from the latest three-month period. Businesses using a 1 April to 31 March accounting period may select calendar update periods, but the submission deadlines remain the same.

Digital Links Requirements for Making Tax Digital

What Is a Digital Link?

A digital link under Making Tax Digital is an electronic transfer or exchange of data between accounting software, spreadsheets or other business applications. Digital links create a continuous digital journey, protect data accuracy and reduce errors caused by manual data entry.

Acceptable Digital Links for MTD Compliance

HMRC accepts various methods for transferring digital records, including:

API transfers between compatible software systems
XML or CSV file imports and exports
Automated transfers between accounting applications
Linked spreadsheet cells using formulas
Downloading and uploading files between software
Emailing spreadsheets containing digital records for import into another system
Transferring digital records using a portable storage device

Transfers That Are Not Digital Links

The following manual methods do not normally meet the MTD digital links requirements:

Copying and pasting data between software programs
Re-entering figures manually into another application
Writing down information before entering it into accounting software
Manually changing or relocating digital records between systems

Maintaining compliant digital links helps businesses create an accurate audit trail and meet Making Tax Digital for VAT requirements. Where multiple software products are used, they should remain digitally connected throughout the VAT record-keeping and submission process. VAT returns must ultimately be submitted to HMRC through an API-enabled solution.

How to Submit an MTD VAT Return to HMRC

Step-by-Step Making Tax Digital VAT Submission Process

Submitting an accurate MTD VAT return requires complete digital records, careful reconciliation and HMRC-compatible accounting software. Follow these steps to complete your Making Tax Digital VAT submission:

Record all business transactions: Enter sales, purchases, VAT amounts and relevant transaction details into your MTD-compatible software.
Reconcile your bank accounts: Match bank transactions with invoices, expenses and accounting records to identify missing or duplicated entries.
Review the VAT calculation: Check output VAT, input VAT, adjustments, reverse-charge transactions and the final amount payable or reclaimable.
Check the VAT return period: Confirm that the correct accounting period and submission deadline have been selected.
Submit through MTD software: Use your accounting software’s API-enabled VAT filing feature to send the return directly to HMRC.
Confirm successful submission: Check the software response or your VAT online account to ensure HMRC has received the return.
Pay the VAT due: Arrange payment early enough for the funds to reach HMRC by the applicable deadline. The deadline is usually one calendar month and seven days after the accounting period ends.

Common VAT Return Submission Mistakes

Avoid these common errors when preparing an HMRC VAT return online:

Claiming VAT on personal or non-business expenses
Applying incorrect VAT rates or tax codes
Omitting purchase invoices or sales transactions
Entering duplicate transactions
Forgetting domestic or overseas reverse-charge VAT
Incorrectly treating imports, exports and zero-rated sales
Claiming VAT without valid supporting documents
Missing the VAT filing or payment deadline

Accurate digital records and regular account reconciliation can reduce mistakes, support MTD VAT compliance and help businesses submit VAT returns to HMRC with confidence.

MTD Bridging Software Solutions for VAT Returns

What Is MTD Bridging Software?

MTD bridging software connects spreadsheets or older accounting systems with HMRC’s Making Tax Digital platform. It allows VAT-registered businesses and accountants to submit VAT returns digitally without completely replacing their existing record-keeping systems.

The software extracts VAT figures from a spreadsheet or compatible accounting application and sends the return to HMRC through an authorised API connection. Businesses using more than one software product must also maintain the required digital links throughout their accounting process.

Benefits of Bridging Software for MTD

Connects spreadsheets and legacy accounting software to HMRC
Enables digital submission of VAT returns
Reduces the need to replace existing accounting systems
Supports businesses managing VAT records in spreadsheets
Helps accountants manage VAT submissions for multiple clients
Improves accuracy by reducing unnecessary manual data entry

Popular MTD Bridging Software Options

Taxfiler: Designed primarily for accountants and tax professionals managing client VAT returns.
Absolute TopUp: Suitable for businesses and accountants using spreadsheets or legacy accounting systems.
Capium: A cloud-based accounting platform suitable for practices managing multiple clients and VAT submissions.

Choosing the Right VAT Bridging Software

Before selecting VAT bridging software, consider spreadsheet compatibility, digital-link support, ease of use, security, pricing and the number of businesses or clients you manage. You should also confirm that the selected solution is currently recognised as compatible with Making Tax Digital for VAT.

MTD Record-Keeping Requirements for UK Businesses

What Digital Records Must Be Kept Under MTD?

Under Making Tax Digital record-keeping requirements, VAT-registered businesses must use compatible accounting software to create, maintain and preserve their required VAT records digitally.

Your MTD digital records should include:

Business name
Principal place of business
VAT registration number
VAT accounting schemes used
Date, net value and VAT rate for supplies made
Date and value of supplies received
Input VAT claimed on business purchases
Output VAT charged on sales
VAT adjustments made during the accounting period
VAT account totals used to prepare the return

Where different software products or spreadsheets are used, the required records should be transferred through compliant digital links. Manual copying and pasting between systems is not considered a valid digital link.

How Long Should MTD Records Be Kept?

VAT records: VAT-related digital records should generally be retained for at least six years.
Making Tax Digital for Income Tax records: Digital income and expense records must be stored for at least five years after the 31 January submission deadline for the relevant tax year.

Businesses should ensure their accounting records remain accurate, secure and accessible throughout the applicable retention period. Proper MTD record keeping supports accurate VAT submissions, simplifies HMRC compliance checks and reduces the risk of errors or penalties.

MTD VAT Penalties and Late Payment Interest

Late VAT Return Penalties: Points-Based System

HMRC uses a points-based system for late VAT return submissions. A penalty point is normally issued whenever a VAT return is submitted after its deadline.

One penalty point is added for each late VAT return
The threshold depends on the submission frequency
Quarterly VAT returns have a threshold of four points
Monthly returns have a threshold of five points
Annual returns have a threshold of two points
A £200 penalty applies when the relevant threshold is reached
A further £200 penalty applies to every subsequent late return while the business remains at the threshold
Points can expire or be reset after the applicable compliance conditions are met

VAT Late Payment Penalties

The previous 2% and 4% rates shown in the section are outdated. Current penalties are:

Up to 15 days overdue: No late payment penalty, but interest may still apply
Between 16 and 30 days overdue: 3% of the VAT outstanding at the end of day 15
31 days or more overdue: 3% of the amount outstanding at day 15, plus another 3% of the amount outstanding at day 30
From day 31: An additional penalty accrues daily at an annual rate of 10% on the unpaid balance

Businesses experiencing payment difficulties should contact HMRC promptly to request a Time to Pay arrangement, which may reduce or prevent further penalties.

HMRC Late Payment Interest

VAT late payment interest is charged from the first day the payment becomes overdue until HMRC receives the full amount. The rate can change because it is linked to the Bank of England base rate; HMRC currently calculates late payment interest at the base rate plus four percentage points.

Exemptions from MTD

Who Can Apply for Exemption?

Those who practice a religion that restricts use of electronic communications
People unable to use digital tools due to age, disability, or location
Businesses subject to insolvency procedures

How to Apply

Contact HMRC and explain your circumstances. Approval is at HMRC's discretion.
