The Social Security retirement income is really important. Your spouse may be on Medicare, and not seeking health insurance, but if they are receiving Social Security retirement benefits, that income, even though it may not be fully taxed, it must be included in the Modified Adjusted Gross Income. Many families have failed to include the Social Security retirement benefits in their income estimated and then found they earned too much money to qualify for the Premium Tax Credit subsidy and they had to pay it all back.
