Taxes for first year

I know its probably different in each state and for different business, but I was wondering if anyone knew the percentage of taxes you may have to pay a year in this kind of small business. This is my first year so I am hoping the start up costs(website, paints, gear, tables, chairs, insurance and such) will be enough to deduct most of my taxes, but I am trying to save just in case I have to pay taxes this year. If someone knows any info would be appreciated!

I've been doing this for 3 years now (and while everywhere is going to be different), I am only now coming out in the black after all deductions that can go on my taxes (including % of mortgage, % of utilities, internet, mileage, etc)... I'm still not having to pay anything yet.
