None of the deductions on Schedule 1-A are allowed for married filing separately, except the deduction for car loan interest. In order to claim the deduction for tips, for overtime, or for seniors you must file jointly if you are married.
The loss of eligibility for many deductions and credits is one of main reasons that filing jointly usually works out better. With the changes in the new tax law, you might find that you are now better off overall if you file jointly, even if it increases your state tax.
