What is MTD?

Making Tax Digital (MTD) is the UK government’s initiative to modernize tax administration through mandatory digital record-keeping and software integration. For VAT-registered entities, MTD requires the use of ‘functional compatible software’ to preserve digital records and submit returns directly via HMRC’s API.

Crucially, MTD does not alter the frequency of VAT returns—whether monthly, quarterly, or annual—but transforms the submission mechanism. By enforcing a seamless digital journey from source data to HMRC, the framework enhances accuracy, reduces transposition errors, and aligns the UK with modern, near real-time compliance standards.

How has MTD evolved? 

Making Tax Digital (MTD) has experienced some setbacks, largely due to COVID-19 disrupting the projected timeline. With the new Labour government, the MTD initiative may (or may not) change. We suggest keeping up-to-date to ensure your business remains compliant.

What is MTD software?

MTD software is a selection of digital financial tools compatible with the Making Tax Digital (MTD) initiative. Its primary function is to send a business’s digital financial records directly to HMRC via HMRC’s API.

One of the MTD requirements is 'digital links'—the electronic exchange of data between software programs, products, or applications without manual intervention. Digital records can be submitted in a range of formats, including XML, CSV, and Excel, provided they are API-enabled. 

These stored financial records must include designatory data and summary VAT data for the period. The format of these VAT returns is a 9-box summary filed via the HMRC’s JSON API platform, which must be digitally linked between the customer’s source data and the submitted digital return. 

MTD software is integral to Making Tax Digital (MTD) because the initiative can’t be rolled out successfully without it. No MTD software means no digital, real-time data for HMRC!

Who is subject to MTD for VAT?

Since 1 April 2022, the scope of MTD for VAT has been universal. The legislation no longer distinguishes based on the VAT registration threshold (currently £90,000). Consequently, all VAT-registered businesses—including those voluntarily registered with lower turnover—must now utilize functional compatible software for every return period.

There are no 'phased' entry dates remaining; compliance with 'MTD for VAT' is mandatory today. Limited exemptions exist only for those who can prove 'digital exclusion' to HMRC, or businesses subject to insolvency procedures.

What are the benefits of MTD software?

While driven by HMRC compliance, the adoption of MTD software offers tangible operational advantages for businesses:

 

Risk Mitigation: By automating data transfer via digital links, businesses significantly reduce the risk of manual transposition errors, thereby minimizing exposure to compliance enquiries and potential surcharges.

 

Financial Visibility: Moving to near real-time digital record-keeping provides businesses with an up-to-date view of their tax position. This enhanced visibility transforms VAT data from a retrospective reporting requirement into a tool for proactive cash flow management and accurate financial forecasting.

What are the challenges of MTD software?

While MTD drives long-term efficiency, the transition presents immediate operational hurdles for many businesses:

Transitional Resource Allocation: The shift requires an upfront investment of time and capital; not just for software subscriptions, but for staff training and the migration of legacy data.

Digital Link Complexity: For smaller businesses accustomed to manual records, establishing compliant 'digital links' (avoiding copy-paste) often requires a steep learning curve or the adoption of bridging software.

Dependency on Connectivity: Unlike paper records, MTD creates a total reliance on software availability and internet connectivity.

Data Security Responsibility: While software providers manage the API security, businesses effectively become data stewards. This necessitates rigorous internal controls and strict access management to protect the digital tax account, though this is a best-practice standard rather than a new regulatory cost.

Avoid penalties for MTD for VAT non-compliance

HMRC currently enforces a two-tier penalty structure: one for process failures and one for lateness.

MTD Compliance Penalties: Failure to adhere to MTD rules triggers specific sanctions. Filing a return without using functional compatible software (e.g., manually typing figures into the portal) can result in a penalty of up to £400 per return. Additionally, failing to maintain digital records or the required ‘digital links’ can attract daily penalties of between £5 and £15 for every day the non-compliance continues.

Late Submission & Payment: The old ‘Default Surcharge’ regime has been replaced by a points-based system for late submissions and a tiered percentage penalty for late payments, alongside daily interest charges.

The implementation of MTD compliant software is one part of the overall MTD transformation that UK businesses need to undertake in the next few years.

Like any overhaul project, Making Tax Digital (MTD) presents both benefits and challenges that each company will need to navigate individually, and this extends to the integration of new financial processes that MTD software will inevitably bring. However, the advantages of MTD software do look promising. The best thing for UK businesses to do right now is get prepared, stay up-to-date with the latest news on MTD, and research software solutions that are suitable for their particular needs and requirements.
