ACA is calendar year while Medicaid is current month based.
I'm trying to figure this out right now.
Colorado.
I'm on ACA Medicaid.
I recently got a part time job. The hours are variable, 0 to 15 hours a week, occasionally more than 15 hours, depending on what projects come up. Most months I will be well under the monthly limit, occasionally I may go over the monthly limit. I did update the CO Medicaid website with my information from my first paycheck which their system calculated my projected yearly income as under the limit. Not sure if they will get some notice from DOL if I get monthly income above what I reported.
I can keep my yearly MAGI income under the Medicaid limit. I can contribute to IRA to lower MAGI if I need to.
I have been searching the web for Colorado specific information but I cannot find helpful specific information. I get info like update the system if your income changes. Every week my hours are different, so yeah, my income changes every two weeks. Many websites just give a chart of the yearly income limits. I suppose I could call someone and ask but I expect even a customer service agent won't really know what to tell me.
I found this on Colorado income verification. It's from 2018 so I'm not sure if there is an updated document.
