2: If I can do IRA. I didn't do it last year for this IRA deduction, can I redo it using 1040X for last year?
3: If part of my after-tax health premium was included in the W-2 box1, and our payroll manager already redid the tax for me as pre-tax premium, I mean she did it as pre-tax health insurance instead of the after-tax option I did. but no new W-2 form, can I just use this new tax calculation for this year's tax return instead of the W-2 form issued to me?
Thanks,
Amy
