Deductions & credits

Hi there,

 

Following up on this question.

Another gave advice to allocate 0-100%between us.

Since our son is filing separately, and was taken off our policy in August how do we allocate?  

Can my husband and I allocate 100% to our son and we take 0%?

Not sure how to do this because our son was not on the policy for 4 months. 

Any assistance is appreciated.

Thank you,

Laura
