Taxes freaking out now please help

[fishnut9]

Ok so i dont know what to do now. I just realized that my wifes business writeoffs are actually deducted from her total income not the actual taxes. That only gives me a couple hundred dollars off. Does anyone know if this is true. She owes 5800$ to the government now here is my question. I want to go to hrblock then have them do the taxes for me. if i dont like the results can i back out for a second opinion. I have 3000 to go towards the taxes. After hr block i will see if i can get a accountant to check it out. Problem is what if he charges me 1000$ leaving me 2000$ for taxes only to have the same number pop up as hr block. Now im 1000$ short. Do accountants allow free evaluations or no. I just dont want to spend the money to get the same results.
