Corporation tax

Every limited company must submit a corporation tax return known as a CT600. Getting this wrong can lead to penalties and unwanted attention from HMRC.

We often see companies paying more tax than necessary because reliefs have been missed or because there has been no planning during the year. We also see directors being told their tax bill only at the last minute which makes cash flow difficult.

We prepare and submit CT600 corporation tax returns, calculate your tax liability, and advise you of the amount well in advance of payment dates. We also review available reliefs, capital allowances and planning options to optimise your tax position.

This is not just about filing a form, it is about making sure your business is structured efficiently.
