Managed IT for
Accountants & Finance.

IT that holds up when filing season won't.

Your deadlines are fixed and your clients trust you with their most sensitive records. An outage on the wrong week means missed submissions and penalties that land on your name. KAVIX keeps your practice running, your data locked down, and your systems ready for Making Tax Digital.

A Practice Runs on Trust
and a Working Deadline.

Break either one and the damage is real. Clients hand you their financials, their identities, and their bank details. HMRC hands you dates that do not move. Your IT has to protect the first and never threaten the second.

Downtime on the wrong week

A server or software outage in a quiet month is an annoyance. The same outage on 30 January stops you filing, and the penalty for a late return lands on your client and your reputation. Peak weeks give you no slack.

Fraud that wears an HMRC mask

During tax season, staff get a flood of emails claiming to be HMRC, clients, or software vendors. One convincing fake, one clicked link, and an attacker is inside the mailbox where your client data lives.

Client records with no way back

Years of accounts, working papers, and correspondence sit in Microsoft 365 and your practice software. Many firms assume that data is backed up. It usually is not, and they find out the week they need it most.

More Filings, More Clients Online,
Less Room for Error.

Making Tax Digital for Income Tax turns one annual return into four quarterly updates per client, plus a year-end declaration. The systems that carry that load need to be current, secure, and available every deadline week. This is where the strain shows.

April 2026
MTD for Income Tax becomes mandatory for sole traders and landlords earning over £50,000.
4 × a year
Quarterly updates per client, due 7 August, 7 November, 7 February, and 7 May, replacing the single return.
2027 & 2028
Thresholds drop to £30,000, then £20,000, pulling far more of your client base into quarterly filing.

Support That Understands
a Deadline Is a Deadline.

KAVIX runs the IT behind your practice so the parts that matter stay up when the pressure is on. Your practice software, your Microsoft 365, and the machines your team files from sit under one managed setup, watched around the clock.

We treat your client data the way your clients expect you to. Security sits on every device, access is controlled, and everything is backed up, so a bad day stays a bad day rather than a breach notification.

The Wrong Week for an Outage.

It is the third week of January and your team is filing self-assessment returns at full tilt. A staff member opens an attachment that looks like a client tax document. By the next morning the practice server is encrypted, and nobody can reach the tax software or the client files.

You have hundreds of returns due on the 31st and no way to file them. The penalties land on your clients, and the apology calls land on you.

With EDR stopping the attack at the first machine, backups that restore your files in hours, and out-of-hours monitoring that catches the intrusion overnight, that same incident is a contained scare instead of a missed deadline. What decides which one you get is what was in place before the email arrived.

Questions Accountancy Practices Ask.

Can you keep our systems up through filing season?
Yes. We monitor around the clock and schedule patching outside working hours, so the run-up to 31 January and every quarterly MTD deadline stays clear of avoidable outages.
Is our client data safe if a laptop is lost or stolen?
Yes. We encrypt and enrol every device, control access to client files, and can wipe a lost machine remotely, so a mislaid laptop does not become a data breach.
Are you ready for Making Tax Digital for Income Tax?
Yes. We keep your practice software and Microsoft 365 current and correctly configured so quarterly filing runs on infrastructure that can take the extra load.
Do you know our practice and tax software?
Our engineers work with the common practice and tax packages alongside Microsoft 365. Tell us your stack and we will confirm exactly what we support.
How do you protect us from tax-season phishing?
We filter the HMRC and client impersonation that spikes at deadline time, verify your domain against spoofing, and train your team to spot what gets through.
What does switching to KAVIX involve during a busy period?
We handle the transition end to end and plan it around your deadlines, so moving to us does not put a filing week at risk.
