Annual accounts & Corporation Tax
Statutory year-end accounts and your CT600 prepared, reviewed with you in plain English, and filed on time with Companies House and HMRC - so you stay compliant and penalty-free.
Every UK limited company has to file annual accounts at Companies House and a Corporation Tax return with HMRC. Miss a deadline and the penalties stack up automatically - £150 and rising at Companies House, plus interest and fines from HMRC.
TaxMag takes the whole job off your hands. We turn your records into a clean set of statutory accounts, calculate your Corporation Tax, and walk you through what the numbers actually mean before anything is filed. No surprises, no last-minute panic.

Annual accounts - your questions
When are my company accounts and Corporation Tax due?
Accounts are normally due at Companies House 9 months after your year end, and Corporation Tax is payable 9 months and 1 day after year end, with the CT600 return due 12 months after. We track all of these for you and file well ahead of time.
What happens if I file late?
Companies House charges an automatic penalty starting at £150 and rising to £1,500 the longer you leave it, and HMRC adds its own penalties and interest. Filing early removes that risk entirely - which is exactly what we do.
My company is dormant - do I still need to file?
Yes. Even a dormant company must file dormant accounts and a confirmation statement. We can prepare and file these for a small fixed fee.
Can you also do my personal tax return?
Absolutely. Most directors need a Self Assessment return too, and we usually handle both together so your salary, dividends and company position all line up.
