I am starting an online retail business and have bought market research tools and website building software. Also I just got a dba. My site is not yet published on the net.
Couple of questions…
what can i deduct as start up deductions?
Did getting a dba officially start my business?
What sort of time restrictions go along with start up tax? ( i bought the software listed above in 07 and got the dba in 08)
what sort of reciepts should I be saving?

I know …I need an accountant but am strapped for cash at the moment. . ,. PLEASE HELP!!! Quality info is needed! thanks!!!
