If you are a limited company, you have to pay corporation tax on your profits. This includes money you make from trading; income from renting property and investment gains. It is calculated and paid annually, based on your corporation tax accounting period – this is usually the same as your financial year. It is your responsibility to tell HM Revenue & Customs (HMRC) how much corporation tax you owe by completing a company tax return every year. We can help you with corporation tax compliance by preparing your corporate tax self-assessment returns; calculating liabilities; corresponding with HMRC; preparing claims and elections and, where appropriate, minimising your tax liabilities.
