Extra income at what rate?

Hi,
I currently work and get paid through PAYE at 41%. I have recently started a very small buisness only about 200-300 profit per month. I just want to know how to pay tax on this does it just add to the other income and warrent 41% or is there another way of working it out.
Thanks in advance

It is just added to what ever else you earn, so in your cause 41% + Income Levy + PRSI. So in reality you need to be keeping over 50% for the tax man at the end of the year.
