Making Tax Digital in the UK 2026: What Changes for LTDs and How to Prepare

The way British companies manage their tax obligations is changing in a structural and irreversible manner. The Making Tax Digital (MTD) programme — launched by HMRC in 2019 and progressively expanding — requires businesses to abandon manual and paper-based processes in favour of entirely digital tax management, using approved software that communicates directly with HMRC systems via API.

For those managing a UK LTD from Italy or another country, MTD is not a future topic to be addressed in due course: some obligations are already fully in force, others will come into effect over the next two years with direct impacts on the day-to-day management of the company. Understanding the programme in detail — what is already mandatory, what is about to become so and how to prepare — is essential to avoid penalties and manage compliance efficiently.

What is Making Tax Digital and what is its objective

Making Tax Digital is the programme through which the British government is digitalising the entire tax compliance system for businesses and taxpayers. The stated objective is threefold: to reduce errors in tax declarations (estimated by HMRC at approximately £9 billion annually attributable to avoidable mistakes), to make tax collection more efficient, and to give taxpayers a real-time view of their tax position.

In practice, MTD requires those subject to it to:

• maintain their accounting records in digital format using approved software
• submit tax declarations directly through the software, without manual access to the standard HMRC portal
• maintain a digital link between all accounting data and the information transmitted to HMRC, with no manual transcription in between

The programme is structured around three main phases, each relating to a different tax: MTD for VAT, MTD for Income Tax (ITSA) and MTD for Corporation Tax.

MTD for VAT — already mandatory for all registered businesses

The first phase of MTD — relating to VAT — is the most advanced and is already fully mandatory for all VAT-registered businesses in the United Kingdom, without exception.

Since April 2022, all VAT-registered businesses, regardless of turnover, are required to:

• maintain VAT records in digital format
• submit VAT Returns exclusively via MTD-compatible software connected directly to HMRC via API
• maintain a digital link between all data feeding into the return, eliminating any manual transcription

This means it is no longer possible to complete and submit a VAT Return by manually accessing the HMRC portal. Anyone attempting to do so will receive an error message. The only way to submit the return is via approved software.

For non-residents with a VAT-registered UK LTD: if you have not yet configured MTD-compatible software, you are technically in breach and face penalties at every quarterly deadline. Software configuration is an urgent and non-deferrable compliance step.

The MTD VAT penalty system — Points-Based Penalty System

Since 1 January 2023, HMRC introduced a new VAT penalty system based on a points mechanism — the points-based penalty system — replacing the previous Default Surcharge regime.

The mechanism works as follows:

Late submission penalties:

• Each VAT Return submitted late generates 1 penalty point
• On reaching the points threshold (which varies based on filing frequency) a fixed penalty of £200 is triggered
• Each subsequent late return generates a further £200 penalty

The points thresholds that trigger the penalty:

• Annual filing: 2 points
• Quarterly filing: 4 points
• Monthly filing: 5 points

Points reset after a period of compliance — generally 24 consecutive months of timely submissions.

Late payment penalties:

• Delay of up to 15 days: no penalty if payment is made by day 15 or HMRC is contacted to agree a payment plan
• Delay between 16 and 30 days: penalty of 2% of the unpaid amount
• Delay beyond 30 days: penalty of 2% calculated on the amount outstanding at day 30, plus a further 2% calculated on the average unpaid balance for the remaining period
• Interest on all late amounts, calculated at the Bank of England base rate plus 2.5 percentage points

MTD for Income Tax (ITSA) — in force from 2026

The second phase of MTD concerns Income Tax Self Assessment (ITSA) — the personal tax return of self-employed individuals and landlords with property income.

The implementation dates are as follows:

• April 2026: mandatory for self-employed individuals and landlords with annual income above £50,000
• April 2027: mandatory for those with annual income above £30,000
• April 2028 (date still under consultation): possible extension to those with income above £20,000

For directors of UK LTDs who also receive self-employment or UK property income above the applicable thresholds, MTD ITSA introduces an additional obligation beyond company management: the submission of quarterly income updates to HMRC via approved software, replacing the current annual return.

In practice, instead of submitting an annual Self Assessment by 31 January, those subject to the obligation will need to:

• submit quarterly updates within 1 month of the end of each quarter
• submit an annual closing declaration (end of period statement and final declaration) by 31 January following the tax year

MTD for Corporation Tax — the most significant change for LTDs

The third and most impactful phase of MTD concerns Corporation Tax — the tax on company profits. This is the phase that directly affects all UK LTDs and represents the most significant change in the programme for entrepreneurs managing a British company.

Current status in 2026:
MTD for Corporation Tax is still in the consultation and pilot phase. HMRC has been running pilot programmes with a limited number of voluntary companies since 2024. The mandatory implementation date has not yet been definitively confirmed, but the most recent HMRC indications suggest a gradual rollout starting no earlier than 2026–2027 for large businesses, with SMEs and micro-entities following in subsequent phases.

What MTD for Corporation Tax will require:

• Maintenance of accounting records in digital format
• Submission of periodic updates to HMRC during the financial year (exact frequency still under consultation — likely quarterly)
• Submission of the CT600 via approved software with direct connection to HMRC
• Elimination of the possibility of submitting the return manually or via the standard HMRC portal

Why prepare now:
Even though the formal obligation is not yet in force, companies that adopt digital MTD-compatible accounting software today are in a position of significant advantage: data is already correctly structured, the accounting workflow is digitalised and the transition to future obligations will require minimal adjustments rather than a complete reorganisation.

MTD-compatible software: the main options in 2026

HMRC maintains an updated list of approved software for MTD. The most widely used solutions among LTDs managed by non-residents are:

Xero
The most widely used solution internationally among SMEs. Offers full MTD compatibility for VAT, direct integration with Companies House and HMRC, real-time dashboard, multi-currency management and connection with over 1,000 third-party applications. Interface available in Italian. The most suitable plan for a small LTD costs between £15 and £42 per month depending on features.

QuickBooks Online
The second most widely used option, with a slightly more accessible learning curve than Xero. Full MTD compatibility for VAT, strong invoice and expense management, integrated tax reporting. The basic plan starts from £12 per month.

FreeAgent
A solution specific to freelancers and micro-businesses, particularly appreciated for its simplicity of use. Full MTD compatibility for VAT. Offered free of charge to customers of certain British banks (e.g. NatWest, Royal Bank of Scotland). The standard plan costs approximately £19 per month.

Sage Business Cloud Accounting
A solution more oriented towards medium-sized businesses with more complex accounting needs. Full MTD compatibility. Prices from £15 per month.

Bridging software
For those using Excel spreadsheets or other systems not natively compatible with MTD, bridging software solutions exist that act as intermediaries: they extract data from the spreadsheet and transmit it to HMRC in the required format. This is an acceptable short-term solution but not recommended as a structural choice, as MTD rules require a complete digital link with no manual transcription.

How to prepare for MTD in 2026: a practical action plan

For a UK LTD managed by a non-resident, the action plan for full MTD compliance in 2026 involves five steps:

Step 1 — Assess your current position
Check whether your company is already VAT-registered: if so, the MTD obligation for VAT is already in force and you must use approved software. If not yet registered for VAT, consider whether the registration obligation applies to your situation.

Step 2 — Choose and configure software
Select an MTD-compatible software from those listed by HMRC. Xero and QuickBooks are the most robust choices for a remotely managed LTD. Configure the connection to HMRC using the company's Government Gateway credentials.

Step 3 — Migrate accounting data
If you are transitioning from a manual system or spreadsheets, migrate historical data into the new software before the first applicable MTD deadline. Most software offers automatic import tools.

Step 4 — Configure the complete digital link
Ensure that all data feeding into the VAT Return — sales invoices, purchase invoices, bank statements — is imported into the software digitally, without manual transcription. The direct bank feed available in Xero and QuickBooks is the most efficient tool for meeting this requirement.

Step 5 — Submit the first VAT Return via MTD
At the first quarterly deadline, submit the VAT Return directly from the software. The software will guide you through the HMRC authorisation process and confirm successful transmission. Retain the confirmation of each submission.

MTD impact for non-residents: specific considerations

For those managing a UK LTD from Italy, MTD introduces some specific practical considerations:

Remote software access
All major MTD-compatible software solutions are cloud-based and accessible from any country via browser or mobile app. It is not necessary to be physically in the United Kingdom to manage digital compliance.

Interface language
Xero is available in Italian. QuickBooks and FreeAgent are primarily in English, but extensive support documentation is available.

Delegation to an adviser
All major MTD software solutions allow access to be granted to a tax adviser or accountant, who can manage compliance on behalf of the director. This is the most efficient solution for those who do not wish to manage the software directly.

Coordination with Italian accounting
For those also managing an Italian company or with tax obligations in Italy, it is important that the UK MTD software and the Italian accounting system are coordinated — particularly to avoid duplication in the recording of cross-border transactions.

Common mistakes to avoid

• Continuing to submit the VAT Return manually via the HMRC portal: this is no longer possible and generates automatic non-compliance
• Using Excel spreadsheets without bridging software as the sole accounting system: this does not satisfy MTD's digital link requirements
• Failing to configure automatic bank feeds, relying instead on manual transcription of bank statements: this violates the digital link requirement
• Waiting for the mandatory extension of MTD to Corporation Tax before digitalising accounting: the cost of late-stage change is always greater than that of an early and planned transition
• Failing to verify that the chosen software is on HMRC's updated list of approved providers: not all accounting software is MTD-compatible

FAQ

Does Making Tax Digital already apply to UK LTDs in 2026?
Partially. MTD for VAT has been fully mandatory for all VAT-registered companies since 2022. MTD for Corporation Tax is still in the pilot and consultation phase in 2026: the mandatory implementation date for LTDs has not yet been definitively set, but the direction is clear and early preparation is strongly recommended.

Can I still submit the VAT Return manually via the HMRC portal?
No. Since 2022 all VAT-registered businesses have been required to submit VAT Returns exclusively via MTD-compatible software. The standard HMRC portal no longer accepts manual VAT Return submissions from businesses subject to MTD.

What is the most suitable MTD software for a LTD managed by non-residents?
Xero is generally the most recommended choice for LTDs managed by non-residents: interface available in Italian, full MTD compatibility for VAT, multi-currency management, automatic bank feed and integration with a tax adviser. QuickBooks Online is a solid alternative at a slightly lower price point.

What is bridging software and can I use it?
Bridging software is an application that extracts data from Excel spreadsheets or other non-MTD-native systems and transmits it to HMRC in the required format. It is accepted by HMRC as a transitional solution, but does not fully satisfy the complete digital link requirements envisaged by MTD in the long term. It is preferable to adopt a natively MTD-compatible accounting software directly.

Will MTD change the quarterly VAT Return deadline?
No. VAT Return deadlines remain unchanged: one month and seven days from the end of the accounting quarter. MTD changes the submission method — from manual to digital via software — but not the timeframes.
