About Taxley
Why we built Taxley
Filing a Corporation Tax return for a straightforward company should be quick, clear and affordable. For a lot of small directors it's still none of those things — so we built the software we wished existed.
The problem
A simple return shouldn't cost a fortune
A dormant company, a small landlord, a one-person consultancy — many UK limited companies have genuinely simple tax affairs. Yet the usual options are an accountant charging £500–£1,500 a year, or wrestling with HMRC's own software that assumes you already speak fluent CT600.
The return itself is often the easy part. What's missing is a tool that walks you through it in plain English, does the tax maths correctly, produces the iXBRL accounts HMRC and Companies House expect, and then files them — for a price that matches the size of the job.
What we believe
The principles behind the product
Pay for the job, not a subscription
One clear fee when you choose to file — shown before you pay, and nothing while you prepare or preview. No retainer, no lock-in.
You stay in control
The figures are yours and the declaration is made by you, not by us. We show every number and the schedule behind it so you can check the return before it goes anywhere.
Plain English over jargon
Guided steps, worked examples and a free calculator — not a wall of box numbers. The technical detail is there when you want it, tucked out of the way when you don't.
Honest about what we are
We're independent software, not an accountant and not HMRC-recognised. We say so plainly, and we tell you when a case is beyond what the tool should handle on its own.
Being straight with you
What we're not
Taxley prepares figures and files them on your instruction — it isn't tax advice, and using it doesn't make us your accountant or agent. HMRC "recognition" is an optional technical accreditation, not an endorsement, and it isn't required to file; we're not recognised, and we don't imply otherwise.
The product is still maturing. Some calculations and the iXBRL tagging carry expert-review flags, and trading companies in particular — capital allowances, loss relief, group structures — usually still need a qualified accountant. We'd rather tell you that up front than pretend a tool can do everything.
