Hi Tax Expert,
For 2021, I lived in Massachusetts and my husband lived in California. We both have income and have house in both states. We have one kid in college in California. In our case, are these steps below correct and tax-efficient (maximize refund)? If not, please advise. Your help is highly appreciated! I am going to useTurboTax Premier.
1. Create an account using my name, file MFJ for federal
2. Create another account using my husband’s name, make a mock MFS for him with only his income and deductions for him and our kid, then efile CA, not including MFJ or MFS
3. Use account with my name, make a mock MFS for myself with only my income and deduction for myself, then efile MA, not including MFJ or MFS
