Thanks Xmasbaby0!
Yes, both of us using the standard deduction.
I claim no dependents for my kids and he claim the kids for dependent credits. both of us don't have education credits and earned income credit.
Both of our tax are simple which don't have any earned income credit, education credits, adoption credits, or deductions for student loan interest. That's why except he claimed dependent credits, we file separately jointly won't give us any much benefit, it will only makes it worse. Because I can be taxed on lower bracket if filed separately. If we filed jointly, I have to be taxed on higher rate which doesn't make sense.
