- Companies House authorised software filing
- Files directly to HMRC
Running a trade? The A.X.E.L platform handles leads, quotes and invoices, free for 14 days. Making Tax Digital filing for Income Tax and VAT comes to A.X.E.L in 2027.
Since 31 March 2026
The free government filing service has closed.
HMRC and Companies House used to let small companies file their accounts and Corporation Tax return together for free. That joint service shut on 31 March 2026. The CT600 now goes through commercial software or an accountant. Accounts can still go to Companies House directly, until software becomes compulsory there in April 2028.
A.X.E.L Filing is that software, built for directors who would rather do it themselves. £49 for both filings. No subscription.
Your year end starts three clocks
- 9 monthsAccounts due at Companies House
- 9 months + 1 dayCorporation Tax due to HMRC
- 12 monthsCT600 return due to HMRC
Every company's dates come from its own year end, so deadlines fall in every month of the year.
Your accountant charges £500+. We charge £49.

Accountant figures are typical published quotes for a micro limited company, checked October 2026. A.X.E.L Filing is a filing tool, not an accountancy service: the figures you file stay your responsibility.

FAQ
A.X.E.L Filing lets the director of a small UK limited company prepare and file their own company accounts to Companies House and their CT600 Corporation Tax return to HMRC, for £49. A.X.E.L is also a job management platform for trades and small businesses: leads, quotes, invoicing, expenses and timesheets in one dashboard.
Not the CT600. The free joint HMRC and Companies House filing service closed on 31 March 2026, so the CT600 now goes through commercial software like A.X.E.L Filing, or an accountant. Companies House still takes accounts through its own online service until 1 April 2028, when software becomes compulsory for those too.
£49 for your accounts and CT600 together, or either one alone. £20 if the company was dormant. It is a one-off payment per filing, with no subscription.
A.X.E.L Filing is built for active or dormant UK private limited companies with a single UK trade that file micro-entity accounts. It is not for groups, R&D claims, property income, chargeable gains, or companies above the micro-entity limits. The free eligibility check tells you in two minutes, before you enter any figures.
It depends on your company's own year end. Accounts are due at Companies House 9 months after it, Corporation Tax is payable 9 months and a day after it, and the CT600 return is due 12 months after it.
If your company is complicated, you should, and A.X.E.L tells you so before you start. But the return is yours either way: if it is late or wrong, the penalty is the company's, not the accountant's. Doing it yourself, you see your numbers whenever you like rather than once a year, for £49.
Plans start from free (10 leads/month) up to £59/month for the full package. All paid plans come with a 14-day free trial. No contracts, cancel anytime.
Yes — all paid plans include a 14-day free trial. You'll enter card details at signup so your subscription starts seamlessly after the trial. The Apprentice plan is completely free forever with 10 leads per month.
No. A.X.E.L works as a standalone platform. That said, if you need a website, we build those too — hand-coded, SEO-optimised, from £497.
A complete 5-page website, hand-coded with React and Next.js. Includes homepage, about, services, contact, and one more page of your choice. SEO-optimised, mobile-first, and fast. Pay once — it's yours. No monthly fees.
Most sites are ready within 1–2 weeks. We agree on content and layout upfront so there's no back and forth.
No. A.X.E.L is built for trades and small businesses alike: contractors, cleaners, consultants, landscapers, handymen and more. A.X.E.L Filing works for any small UK limited company, and if you manage leads and jobs, the platform is built for you too.
For websites: hosting is included at no extra cost. For A.X.E.L: it's a cloud platform — just sign up and go. Nothing to install.
