Medicare tax increase
Since 2013, many higher-income taxpayers have experienced an increase in their Medicare tax on earned income, as implemented by ACA. Filing categories affected include:
- individuals who earn more than $200,000
- people married filing separately who earn more than $125,000
- joint filers who make $250,000 or more
Such earners can expect to pay 0.9 percent extra in Medicare taxes. That means Medicare taxes will range from 1.45 percent to 2.34 percent.
Unearned income tax increase
The ACA imposes a 3.8 percent tax on unearned income as a Net Investment Income Tax. This affects higher income individuals with these thresholds:
- individuals who make more than $200,000 and file single
- married taxpayers who earn over $250,000 and file jointly
- married individuals who file separately and make over $125,000
Unearned income affects net investment income which includes:
- gross income from royalties, rents, annuities and dividends
- certain capital gains
- passive business activities that have pass-through income
Tax is imposed on the modified adjusted income that exceeds the thresholds. The tax is levied on the lesser of annual investment income, or the amount the MAGI exceeds the threshold limit.
TurboTax Tip:
Many of the people eligible for Medicaid have children who now qualify for Children’s Health Insurance Program (CHIP).
Increasing access to Medicaid
The ACA has put into place a means that allows Medicaid to insure a number of previously uninsured individuals. Prior to ACA, states were only allowed to cover childless individuals with Medicaid by applying for a special waiver from the federal government. Under ACA, a state has the option to cover these people without a waiver, provided they are within 138 percent of the federal poverty level. To determine eligibility, an individual must complete a tax filing. The 138 percent mark of the federal poverty level is $20,120 per year for 2023, according to the U.S. Department of Health and Human Services.
Children's health insurance program
Under the ACA, the Children’s Health Insurance Program (CHIP) has seen some changes. CHIP falls under Medicaid’s umbrella. As of publication, any person under age 65 who has an income that falls within 138 percent of the federal poverty level is now eligible for Medicaid. Many who fit this criteria have children who qualify for CHIP. Determination as to whether a person falls into this category is generally determined by completing an income tax return. The program is administered by states, according to federal requirements.
