What is the difference between drawing account and expense account?

A Drawing account is used for withdrawals by owners of the entity. This is commonly used in sole proprietoships and partnerships. The withdrawals are the distribution of the profits to the owners. In corporations dividends declared reduce retained earnings in a similar manner because dividends are distributions of profits to the stockholders. An expense account is used for costs incurred by the entity such as salaries, depreciation, rent, interest, insurance, advertising, and taxes.
