Marketplace Health Insurance 1095-A allocation question

[jgao]

So I was a student in the first half of 2021, then I had got employed  in June, so from January to June I've had a Marketplace Health Insurance with my Mom. Then I switch to my workplace Health Insurance in July to December. Now We are filing taxes separately for 2021,  When filling out the information from the 1095-A form do I enter in the amounts for January to June and leave the rest blank? and when asked about allocations, do I fill in 50% for all 3 boxes? 

also would we both have to fill out the 1095-A form on the tax return?

Are you referring to having a spouse and married filing jointly?  Fill out the 1095-A information exactly as it appears on the form.  There is question asking if you shared the plan with another person and the percentage for each person.

It's just me and my Mom on the plan, and I am only on there from January to June, from July to December I have my own plan from my work.

[GeorgeDenseff]

You still fifi out the form using 1095-A and then you and your mom can allocate what percentage each of you want to claim.  The only requirements are that both percentages add up to 100 and that you both agree.

That part I do understand, maybe I'm not being clear enough.
I am only on the marketplace plan from January to June, Do I only fill out the credit boxes for January to June from the boxes? or do I fill out all the boxes from January to December? as I only want to claim credit for 50% for January to June.

For example,

let's say on the 1095-A form January to June the credits were 500 for both of us,

and from July to December the credits were 250 since it is just my mom.
So do I fill out every month in my tax return or just the months I had the plan?
I only fill out the credits for January to June, and leave July to December  blank. and I want to claim 50% of the credits for January to June.
or do I fill out every month like it is on the 1095-A?
My mom's tax return she would have to fill out January to December credits, would she also claim 50%? or should she put 75%?
How would they know that she's claiming 50% for January to June and 100% for July to December?

[GeorgeDenseff]

You both fill in the form exactly as it is on the 1095-A.  Then you decide between you on the amount that each will be allocated.  The IRS does not care which months each of you were insured through the marketplace.  Just keep that information for your own records in case you are ever audited or asked for more information.
