<prompt> Human: My boyfriend and I have discussed marriage over the past year or so. We are both interested in how it would effect or income tax filing next year. Pertinent facts:1. He owns our home outright2. He has zero debt, as do I. I paid off my student loans 2 months ago so this will be the last year I can deduct my interest payments on that. 3. I have a 6 year old son that I claim every year. 4. I make a salary of 59,000year. He makes approximately 133,000year after bonuses. It looks like at least this years tax brackets wed stay in the tax bracket hes been in. So what effect do you think this will have on our taxes? Thanks in advance.  <response>: Without a child, it would save you a few hundred dollars per year. But with the child it actually costs you about 2000 a year to get married because you lose the 1000 child tax credit due to your high combined income and some deductions get phased out. Basically youre a moderate income single mom becoming a high income married couple and the tax code is designed to give the former some breaks that the latter doesnt get. As others have said, put it into an online calculator, but make sure you use one that asks about dependents.
