Statutory year-end accounts prepared & filed at Companies House
Corporation tax computed and filed correctly with HMRC
Accounts tagged in the digital format HMRC requires
Every Companies House and HMRC deadline tracked for you
Your accounts and corporation tax return are prepared together, by a Chartered Accountant, with nothing left for you to chase or second-guess.
Full preparation of your year-end accounts in the correct statutory format — FRS 105 for micro-entities or FRS 102 Section 1A for small companies — ready to file at Companies House.
AnnualWe calculate your corporation tax, prepare and file the CT600 return with HMRC, and tell you exactly how much to pay and when — no nasty surprises near the deadline.
HMRCYour accounts and tax computations are tagged in the iXBRL format HMRC requires — handled entirely by us, with no special software needed at your end.
ComplianceWe file your accounts and your annual confirmation statement, keeping your company's public record accurate, current and penalty-free.
FilingWe track every Companies House and HMRC date for you and prepare well ahead — so a missed filing penalty is one thing you'll never have to think about.
Peace of MindMore than box-ticking. We look for allowances, reliefs and a salary/dividend mix that legitimately lower your bill, and flag planning points before your year-end, while there's still time to act.
Tax SavingsYear-end accounts and your corporation tax return are included in every Lumi package — from Lite upward. What changes between tiers is the bookkeeping, VAT and advisory support that surrounds them.
All packages include a Xero subscription (our recommended software). View full package details →
Because we keep your bookkeeping current through the year, your year-end isn't a frantic scramble — the accounts almost prepare themselves, and we have time to plan rather than just file.
You deal directly with a qualified ICAEW Chartered Accountant — not a call centre or a different junior every year.
Your accounts are prepared and reviewed by a Chartered Accountant — the gold standard for technical accuracy and trust.
We explain what your numbers mean and what to do about them — no jargon, no acronym-soup, no pretending it's more complicated than it is.
We work to your dates well in advance and chase what we need from you, so late-filing penalties simply don't happen.
Your accounts and tax are part of one transparent monthly fee — no hourly billing, no year-end invoice shock.
