For tax years beginning January 1, 2013, the tax law imposes a 3.8 percent surtax on certain passive investment income of individuals, trusts and estates. For individuals, the amount subject to the tax is the lesser of (1) net investment income (NII) or (2) the excess of a taxpayer's modified adjusted gross income (MAGI) over an applicable threshold amount.
The applicable threshold amounts are shown below.
Married taxpayers filing jointly $250,000
Married taxpayers filing separately $125,000
All other individual taxpayers $200,000
A simple example will illustrate how the tax is calculated.
Example. Al and Barb, married taxpayers filing separately, have $300,000 of salary income and $100,000 of NII. The amount subject to the surtax is the lesser of (1) NII ($100,000) or (2) the excess of their MAGI ($400,000) over the threshold amount ($400,000 -$250,000 = $150,000). Because NII is the smaller amount, it is the base on which the tax is calculated. Thus, the amount subject to the tax is $100,000 and the surtax payable is $3,800 (.038 x $100,000).
Fortunately, there are a number of effective strategies that can be used to reduce MAGI and or NII and reduce the base on which the surtax is paid. These include (1) Roth IRA conversions, (2) tax exempt bonds, (3) tax-deferred annuities, (4) life insurance, (5) rental real estate, (6) oil and gas investments, (7) timing estate and trust distributions, (8) charitable remainder trusts, (9) installment sales and maximizing above-the-line deductions. We would be happy to explain how these strategies might save you large amounts of surtax.
