Thanks for your reply, though still not clear. Realised I should ask for more in-depth answer.
I own 10% of the shares in the company which I paid for.
In the tax year 2014-2015 I took circa £60,000 of my salary in shareholders dividends on which I will pay personal tax.
The company now calculates it owes HRMC £80,000 in corporation tax. Am I personally liable to pay any of this corporation tax as I am NOT a director of the company?
The company is responsible for the corporation tax, not the shareholders or employees. For example, if Barclays didn't pay its corporation tax. HMRC wouldn't go to the shareholders to get the money. In some situations, the company directors can be held responsible for a company's debts including tax.
