Where should I do my taxes?

[Ryan Dossey]

I have always been a turbo tax user. I got married in 2014. That is the only thing that has changed. I'm puzzled as I entered all of our info into both turbotax and taxact and got extremely different results. 

Turbotax: No federal refund. State 200 back.

Taxact:Federal 500. State I owe 2500. 

I have double/triple checked everything and it is all entered the same... Hence I am thinking I should probably go with a professional this year. 

Only weird thing my wife was a nanny for a few months and the family DID NOT set up an EIN and remove taxes like they are supposed to. They paid her cash under the table yet claimed the as a deduction on their end. From what we have read the IRS is cracking down on that. But just like last year we claimed she "owned a business from home". 

Last year we both got a large amount back. (separately)
