A limited company is generally strongly favoured by the taxation regulations. It is subject to tax but its profits are not normally subjected to higher rates of tax - unlike income tax. Directors do pay tax but they are entitled to claim all the usual personal allowances against their income.
The profits of a partnership are divided for tax purposes amongst the partners and they are assessed personally to tax on these amounts at once even if they have not actually drawn any cash out of the business.
 
With good tax planning, including the implementation of a company pension fund it is possible for your accountant to allay a considerable amount of tax and in most cases negate all corporation tax completely.
 
Whilst a good accountant can help you in the reduction of your tax he should also be able to assist in demolishing the old myth that the administration of a limited company costs more than any other form of business and is more cumbersome. If your accountant says that administering your limited company will cost more than you could otherwise save then perhaps you should investigate a new accountant.
