HMRC's free service closed — here's the better way
Your company's accounts and tax return. Done in an afternoon.
Answer plain-English questions. Watch your Corporation Tax calculate itself. Companies House filing is proven on their real gateway; HMRC filing switches on with our software recognition — no accountant, no spreadsheets, no jargon.
"An afternoon" assumes a straightforward micro or small company with its records to hand — see exactly what we cover on the what-we-support page.
Your tax, as you type
£100,000 taxable after full relief on the equipment — includes £2,250 marginal relief, found automatically. Pay by 1 January 2027.
Security & trust
Your filings, treated like they matter
Credentials never stored
Your Government Gateway login and Companies House code are used once, in memory, at the moment of filing — there is nowhere in our database to store them.
Official government gateways
Every filing travels through Companies House's official XML Gateway and HMRC's official submission service — the same routes professional software uses.
Built like it matters
Encrypted in transit, UK-hosted data, hashed sessions — and every calculation locked by hand-verified tests against the published tax rules.
Three steps. Both filings.
Find your company
Type your company name. We pull your details and every filing deadline straight from Companies House — before you've paid a penny.
Answer plain questions
Money in, money out, what's in the bank. About fifteen questions, no accounting jargon — your tax bill updates live as you type.
Check your finished filings
Review your finished accounts and tax return exactly as they'll be filed, enter your government credentials securely, and submit through the guided filing process.
Guidance at every step — in plain English
Every question explains itself as you go, and our guides cover the things directors actually ask. Written in plain English and checked against published HMRC guidance — no jargon, no 40-page PDFs.
GoTaxes is filing software with clear guidance, not a regulated tax adviser — if your situation is unusual, we'll say so and point you to a professional rather than guess.
What can I claim as expenses?
Rent, software, travel, phone — what counts, what doesn't, and the grey areas.
Salary or dividends?
How director pay affects your Corporation Tax, in numbers not theory.
My first year filing
The deadlines that matter, what happens if you're late, and how to never think about it again.
Equipment and the £1m allowance
Why the laptop you bought is 100% deductible this year.
Made a loss this year?
How losses carry forward and quietly cut next year's bill.
What is marginal relief?
The 19%–25% sliding scale, and why we calculate it automatically.
One price. Both filings. No surprises.
Others charge extra for Companies House filing, director's loans, or fixing a mistake. We don't. Prepare everything free — pay only when you're ready to file.
