Making Tax Digital (MTD) is transforming the way UK businesses manage and submit their tax information. At the same time, GDPR continues to place strict responsibilities on organisations that handle personal data. For many businesses, these two areas overlap more than they might realise.

At Edmondson's, we regularly speak to business owners who are unsure what systems they may need, or whether their current setup is compliant. The good news is that with the right hardware, software and processes in place, meeting both MTD and GDPR requirements becomes far more straightforward.

What Making Tax Digital Means for Your Business

Making Tax Digital is a government initiative that requires businesses to keep digital records and submit tax returns using compatible software. VAT registered businesses are already affected, and Income Tax Self Assessment requirements are being introduced in stages.

MTD means you can no longer rely on paper records or disconnected spreadsheets. Your financial data must be stored digitally and submitted through approved software. That digital shift brings efficiency, but it also increases your responsibility to protect sensitive financial information.

Why GDPR Still Matters

GDPR applies to any organisation that processes personal data. That includes customer names, addresses, email addresses, payroll data and financial records. If you are storing tax records digitally to meet MTD requirements, you are almost certainly processing personal data.

Under GDPR, you must ensure that personal data is secure, protected against unauthorised access and only retained for as long as necessary. You must also be able to demonstrate that you have appropriate technical and organisational measures in place. That’s where IT infrastructure becomes critical.

The Hardware You Should Have in Place

To meet both MTD and GDPR requirements, your hardware needs to be reliable and secure.

Business-grade computers and laptops are essential. Consumer devices often lack the security features needed for professional environments. Devices should support full disk encryption, secure boot and modern operating systems that receive regular security updates.

A secure router and firewall are equally important. Your internet connection is the gateway to your systems. A properly configured business firewall helps prevent unauthorised access and reduces the risk of cyber attacks.

Secure backup solutions are non-negotiable. Whether you use encrypted external drives or a secure cloud backup service, your financial data must be backed up regularly. Hardware failure, theft or ransomware can otherwise bring your business to a halt.

At Edmondson's, we assess your existing setup and recommend practical upgrades that fit your business size and budget.

The Software You Need to Be Compliant

Choosing the right software is central to MTD compliance; You need MTD compatible accounting software such as Xero, QuickBooks or Sage. These platforms allow you to keep digital records and submit returns directly to HMRC. However, simply installing the software isn’t enough. It must be configured correctly, with secure user access controls and strong passwords.

You’ll also need endpoint security software on all devices. This includes antivirus, anti-malware protection and ideally advanced threat detection. Cyber criminals increasingly target small and medium-sized businesses because they assume defences are weaker.

Secure cloud storage and collaboration tools should also be implemented. If staff are accessing financial data remotely, the platform must use encryption in transit and at rest. Multi-factor authentication should be enabled wherever possible.

Finally, ensure that your software is kept up to date. Outdated systems are one of the most common causes of data breaches.

Policies, Processes and People

Hardware and software are only part of the picture. Staff training is vital. Employees should understand how to recognise phishing emails, create strong passwords and handle personal data responsibly.

You should also have clear data retention policies, access controls and documented procedures for responding to a data breach. GDPR requires accountability, not just good intentions.
