Corporation Tax for Limited Company in London
Corporation Tax for a limited company is the tax your business pays on its profits, currently set at rates between 19% and 25%, depending on how much your company earns. If you run a limited company in London, you’re legally required to calculate this tax yourself, file a CT600 with HMRC, and pay what’s owed within nine months and one day of your accounting period ending — even though HMRC won’t send you a reminder.
Most business owners don’t realise how unforgiving the deadlines are until they’ve missed one. Late filing brings an automatic £100 penalty that climbs the longer it’s left unpaid, and HMRC charges interest on top of whatever Corporation Tax is overdue. Our team handles the entire process for limited companies in London — from working out your taxable profit to preparing and submitting your CT600 — so you’re never caught off guard by a deadline or a penalty notice.

Why Managing Corporation Tax for Limited Company in London is Essential?
Properly managing your corporation tax for limited company in London is about protecting your business and keeping finances under control. It also helps you ensure you’re not paying more than you should. Here’s why corporation tax for limited Company matters:
Every limited company registered in the UK must file a Corporation Tax return, regardless of whether it made a profit or a loss. This isn't optional — HMRC expects accurate reporting from the day your company starts trading, and missing this duty can lead to fines, investigations, and in serious cases, director disqualification.
Knowing your Corporation Tax liability in advance means you can plan your cash flow properly instead of scrambling to find funds when the bill arrives. Limited companies in London that budget for tax throughout the year, rather than treating it as a year-end shock, tend to avoid the late payment interest that HMRC adds daily.
Lenders, investors, and even potential business partners often ask to see your Corporation Tax filing history before agreeing to work with you. A clean record of on-time, accurate filings signals that your company is well-run and financially stable — something that matters more than most directors expect when it comes to securing funding or contracts.
HMRC penalties for Corporation Tax start at £100 for being just one day late and increase the longer the delay continues. If your return is six months late, HMRC can also estimate your tax bill and add a 10% penalty on top of any unpaid tax — a costly mistake that's entirely avoidable with proper filing support.
