R14 000 income per month for a year how much return can expect to pay?

I started my business in 2013 June I started buy material for my business I never paid tax before every month I get ± R14000 how much can I maybe be owing?

Did you register a business or is this in your personal name?

Its registered.

Tax on a company is paid at 28% of the profit per financial year. So depending on your profit amount you would need to work out 28% of that.
