The IT Support Checklist for UK Accountancy Practices

Why accountants cannot treat IT as an afterthought

Accountancy practices sit on a goldmine of sensitive information: financial records, National Insurance numbers, bank details and confidential business data for every client on your books. That makes you both a prime target for criminals and a business with serious data-protection responsibilities. On top of that, your calendar has immovable deadlines. An outage on 31 January is not an inconvenience; it is a crisis.

This checklist is written for practice owners and managers, not IT specialists. Work through it to spot the gaps in your setup before they cause a problem. If you would like the full picture for accountancy firms, we have a page dedicated to it, but the essentials below apply to practices of every size.

Protecting client data

This is the foundation. Get this wrong and everything else is at risk.

• Multi-factor authentication (MFA) on everything. Email, practice-management software, tax software, cloud accounting and online banking. A stolen password should never be enough to get in.
• A password manager for the whole team. No reused passwords, no shared logins on sticky notes. Every account gets a strong, unique password.
• Encryption on all devices. Every laptop and phone should be encrypted so a lost device does not become a reportable data breach.
• Strict access control. Staff should only be able to reach the client data they actually need. Review access whenever someone joins, changes role, or leaves.
• A clear process for secure file sharing. Emailing sensitive documents as plain attachments is risky. Use a secure portal or encrypted sharing so client data is protected in transit.
• A breach plan. Know in advance who to call, and remember your duty to report a qualifying personal-data breach to the ICO within 72 hours.

Staying online through tax season

Your busiest periods are exactly when downtime hurts most. Resilience is not a luxury for a practice; it is part of the service you sell.

• Backups that are tested, not assumed. Follow the 3-2-1 rule and, crucially, actually restore a test file. Remember that cloud tools like Microsoft 365 are not a full backup on their own.
• A backup internet connection. A second line, or a 4G/5G failover, keeps you working if your main connection drops. During self-assessment season this can save your deadline.
• Cloud-based software you can use from anywhere. If a laptop dies or the office is inaccessible, staff should be able to pick up on another device without missing a beat.
• A support provider who responds fast. Know your provider’s response times, and make sure they are ready for your peak periods rather than caught out by them.

The worst possible time to discover your backup does not work is at 11pm on 31 January. The whole point of this checklist is to find the gaps in June, not on deadline day.

Meeting Cyber Essentials and your professional obligations

For a practice handling sensitive financial data, Cyber Essentials is close to essential rather than optional. It is the UK government-backed certification, run by IASME on behalf of the NCSC, that confirms you have five basic security controls in place.

For accountants it does three useful things at once:

• It reassures clients and professional bodies that you protect their data properly.
• It is increasingly expected by larger clients before they will work with you.
• It gives you a clear, structured checklist so nothing important is missed.

Pair it with the data-protection basics your regulatory and professional duties already require, and you have a defensible, well-documented position if anyone ever asks how you keep client information safe.

Managing the software you rely on

Practices run on a specific stack of tools, and each one needs looking after.

• Keep everything updated. Tax software, practice-management systems, operating systems and browsers. Automatic updates close the flaws attackers rely on.
• Watch your licences and renewals. An expired licence at deadline time is an avoidable disaster. Keep a simple register of what you use and when it renews.
• Be careful with integrations. When tools connect to each other or to bank feeds, make sure only trusted, current connections have access.
• Protect your email domain. Set up SPF, DKIM and DMARC so criminals cannot send emails pretending to be your practice, a common route into invoice fraud that targets firms handling client money.

Getting the right support

General IT support is fine for a general business. An accountancy practice benefits from a provider who understands your deadlines, your software and your duty to protect client data. Look for:

• Genuine experience with practices like yours.
• Fast, clear response times, with extra readiness around your peak seasons.
• A proactive approach that prevents problems, rather than only reacting once something breaks.
• Straight-talking advice with no jargon and no scare tactics.

Our managed IT services and cyber-security support are built for exactly this, and we work with UK accountancy practices who want their IT handled so they can focus on their clients.

If you are not sure where your practice stands, the simplest next step is to find out. Book a free IT and security review and we will go through this checklist with you, highlight anything that needs attention, and give you a clear plan, well before your next deadline.
