Thanks for asking your question! I'm sorry to hear about your tax issue and I'm going to try my best to help you understand or resolve it.
How are you today?
I am going to calculate your self employed income based on $120,000 net and then your spouse's earnings
Based on the information you gave, I ran it through the TaxCaster, and I came up with a tax liability of $32,724
You can play around with the figures yourself, by going to the following web address:
The calculation is based on 2012, but the 2013 amount should not vary by much.
Is there anything else that I can assist you with today?
If not, please rate my response as "excellent" so that I may receive credit for assisting you today. Thanks again
