<prompt> Human: My wife and I have been together for 5 years, have lived together for 4 years, but are not legally married. We had a child in January, she sold her house, and together we just bought a house last month. We both work and make a little over 100k combined. We would like to legally get married but would she get a better tax return next year if she is a single mom who just purchased a house? Edit: We have planned a wedding before but a family member become terminally ill and things got put on hold. We will eventually get married, BUT we can wait a few more months if she would get a better tax return.  <response>: You should get married ifwhen you two are married, not mainly driven by finances. If you bought the house together you already did something that most of us would tell you not to.
