Deductions & credits

@DaveF1006 

 

Thanks for taking time to respond. Just to ensure I conveyed my thoughts clearly, 

 

if I filed MFJ, I get to deduct $25k

if I file MFS, my calculations come to $6.25k each which is $12.5k. 

I would expect it would be 12.5k each which is half of MFJ and together it is 25k.

 

Is the disadvantage here correct?
