About UK Corporation Tax Return (CT600)
A clear overview, in simple terms — what it is, why it matters, and how we handle it.
UK companies pay corporation tax at 19% on profits up to £50,000, 25% on profits above £250,000, and an effective rate in between through marginal relief (limits are shared among associated companies). Tax is payable nine months and one day after the year-end, and the CT600 return is due 12 months after it. Companies must register for corporation tax within three months of starting to trade.
Group companies — for example a UK subsidiary of an Indian parent — share the £50,000 and £250,000 limits with associated companies, which often pushes them to higher effective rates.
We prepare the computation and return with partner UK accountants and coordinate transfer pricing and Indian tax credits on dividends.
| Small profits rate | 19% (up to £50,000) |
|---|---|
| Main rate | 25% (above £250,000) |
| Payment | 9 months + 1 day after year-end |
| Return | 12 months after year-end |
| Associated companies | Limits divided between them |
