I'm not really concerned about the property taxes deduction on the Schedule A form because the Homestead Property Tax Credit on the Michigan State side is larger than the deduction I get on the federal side.
We don't file jointly and we're not married but we both are liable for the property taxes but only I'm liable for the mortgage because the other person's name is not on the mortgage but is on the deed.
I mostly just need to know that if I amend my Michigan State taxes for 2017 do I still have to amend my federal taxes for 2017? Michigan state allows for 4 years while the FED only allows for 3.
