Really depends on your situation and the type of accountant you hire, if you go to chinese cpa office, it's usually pretty cheap (provided you have simple tax situation), like $50 -$100, if you goto american cpa, can start from $200...

if your situation is simple, e.g. using standard deduction, why don't you do it yourself?  

Give TurboTax a try first.  It's very simple to use.
