For MFS, the income limits are different for determining how much of SS is taxable...i.e. IF you lived with your spouse at any time during 2024, and you/she decide to file MFS, then her SS is likely to be taxed at 85% even if she had no other income.
Testing the MFS situation can get messy.....but OK if you aren't in a rush
1) For the "Desktop" software, you usually need to create separate tax files (though there is a What-IF worksheet one can use after a MFJ tax return has been prepared (NOT filed).
2) For the "Online" software, you need to create separate accounts for MFJ, and each MFS tax file to see what happens.....AND...if one MFS person uses itemized deductions, the other one must also use it, even if the other one has no itemized deductions to enter.
