Why CompanyTaxes
Fixed-fee company accounts.
No nonsense.
Traditional accountants charge monthly retainers, chase paperwork, and disappear at deadline. We do one thing exceptionally well — get your year-end filed — for one honest fee.
From £79
Fixed-fee packages from £79 for dormant companies, quoted upfront from your Companies House data.
10 days
Standard turnaround from receipt of your records to filed with Companies House and HMRC.

A permanent 10% discount from your second year onwards, automatically applied.
Your online account
One place to track all your companies.
See every company, filing deadline and year-end status at a glance. Your records, messages and completed filings stay together, so you always know what is happening.
One price. In writing. Before you pay.
You pick your package and pay a single fixed fee — no hourly billing, no deadline surcharges, no surprise invoice months after your year-end. If your records show the work needs a different package, we tell you the exact difference first and you decide.
- Fee shown alongside your filing deadline
- No rush, late or priority fees — ever
- Nothing extra charged without your approval
