Obamacare tax – who will feel the impact
High-income-earners have other factors to keep in mind when mapping out year-end plans. For the first time, they have to take into account the 3.8% surtax on unearned income and the additional 0.9% Medicare (hospital insurance, or HI) tax that applies to individuals receiving wages with respect to employment in excess of $200,000 ($250,000 for married couples filing jointly and $125,000 for married couples filing separately).
The surtax of 3.8% is assessed on all unearned income earned in excess of the floor, explained below. Unearned income includes all types of passive income, including interest, dividends, capital gains and income from passive flow through entities. The surtax is 3.8% of the lesser of: (1) net investment income (NII), or (2) the excess of modified adjusted gross income (MAGI) over an unindexed threshold amount ($250,000 for joint filers or surviving spouses, $125,000 for a
married individual filing a separate return, and $200,000 in any other case). As year-end nears, a taxpayer’s approach to minimizing or eliminating the 3.8% surtax will depend on his estimated MAGI and NII for the year. Some taxpayers should consider ways to minimize (e.g., through deferral) additional NII for the balance of the year, others should try to see if they can reduce MAGI other than unearned income, and others should consider ways to minimize both NII and other types of MAGI.
The additional Medicare tax may require year-end actions. Employers must withhold the additional Medicare tax from wages in excess of $200,000 regardless of filing status or other income. Self-employed persons must take it into account in figuring estimate tax. There could be situations where an employee may need to have more withheld toward year-end to cover the tax.
