Director ltd company

As a Director of a Limited Company, you should be aware that the Companies funds are not yours to do with as you wish, but belong to a separate legal entity of which you are a Director. As such you need to comply with the companies acts.  You can pay yourself a Salary - which will be subject to PAYE in the normal way and if this is the case you should operate a PAYE scheme accordingly. Or if the company makes profits or has retained profits it may decide to pay some of the profits out to its shareholders ( which you may well me a shareholder) in which case Dividends will be paid  after the company has computed corporation tax and will in the receipt of the Director be subject to Income tax on your self assessment tax return. 

In the case of salaries they would be classified as an expense

In the cast of a dividend they would normally be classified as an other expense, thus being "below the line" and show at the bottom of the profit and loss report.
