Tax filing, automated.
Built over more than a decade, ready for what's next. Basetax exists for one simple reason: filing your tax shouldn't be painful. Most of the process can be automated — and we've spent years proving it.
A problem technology could quietly solve.
The idea behind Basetax took shape in 2010, long before "Making Tax Digital" was a phrase anyone used. The belief was straightforward: the manual, last-minute scramble most people go through every year was a problem technology could quietly solve.
So we started building. Over time, that software grew into a full, ICAEW-supervised accountancy practice — and it worked. Clients found us and stayed, some since 2014, trusting a platform that did the job long before it carried a brand to match.
"That loyalty is the proof we point to most — clients who stayed since 2014, long before the platform carried a brand to match. The idea was right from the start."

Why now.
The biggest change to personal tax administration in a generation — and exactly what Basetax was designed for.
From 6 April 2026, Making Tax Digital for Income Tax becomes mandatory for self-employed people and landlords with qualifying income over £50,000 — meaning digital record-keeping and quarterly submissions to HMRC through compatible software.
MTD becomes mandatory · over £50,000
Self-employed people and landlords with qualifying income above £50,000 must keep digital records and submit quarterly to HMRC through compatible software.
Threshold lowers to £30,000
The qualifying-income threshold drops, bringing many more sole traders and landlords into Making Tax Digital.
Threshold lowers to £20,000
The threshold lowers again to £20,000 — extending digital, quarterly reporting across most self-assessment taxpayers.
It's exactly what Basetax was designed for, more than a decade ago. So we've relaunched: a new brand, significantly slicker software, and a sharper experience — built around the way tax is now going, not the way it used to be.
