Should I claim my adult son as a dependent or will the prohibit him from benefitting from Marketplace health insurance subsidies?

[JohnB5677]

You may not wish to claim him as a dependent.

• If you claim him, you are required to provide health insurance for anyone whom you claim as a tax dependent.
• The household would include You, (Your souse), and all of your tax dependents.
• The Marketplace counts estimated income of all household members.
• So, the marketplace policy would be based on his and your income.

Please so this HealthCare article Count income & household size.
