ObamaCare & Form 1040

If you or a family member enrolled in health insurance coverage through your employer, your employer must issue a Form 1095-B or 1095-C.
This form provides the required information on a monthly or annual basis to complete IRS Form 8962. Form 8962 is used to calculate a Premium Tax Credit or a Repayment on your current year's tax return.
Your employer has also reported this information to the IRS.

You may be eligible to claim the premium tax credit on your 2016 tax credit if you, your spouse, or a dependent enrolled in health insurance through a Health Insurance Marketplace and your household income falls within specific criteria.
The credit provides financial assistance to pay the premiums by reducing the amount you owe or increasing your refund amount.
If the marketplace overestimated your income when they calculated your advance payment then you will probably receive a refund. If the marketplace underestimated your income then you will have to repay a portion of the advance payment. The premium tax credit will be reported on IRS Form 8962. Both the credit or additional tax due transfer to Form 1040.

If the marketplace underestimated your income when calculating your advance payment and you do not claim any health coverage exemptions then you will probably have to repay a portion of the advance payment. The premium tax credit will be reported on new IRS Form 8962.
Other factors that can cause a penalty calculation is that you received a advanced payment and your filing status is married filing separately or as a dependent of another or your household income is above or below certain limits.

If you do not have health insurance coverage for all 12 months in 2016 you may have to make a penalty payment with your tax return unless certain other conditions exist.
Individuals for whom coverage is too expensive are exempt from the penalty payment. Also individuals may qualify for a coverage exemption. A coverage exemption can be granted from your marketplace or you may qualify for a coverage exemption based on your household income or gross income being below certain threshold amounts.
Individuals may also qualify for certain hardship coverage exemptions based on their family circumstances. The Shared Responsibility Penalty Payment will be reported on Form 1040, line 61. The coverage exemptions being claimed are reported on new IRS Form 8965.
