As part of ThinkAdvisor’s Special Report, 21 Days of Tax Planning Advice for 2014, throughout the month of March, we are partnering with our Summit Professional Networks sister service, Tax Facts Online, to take a deeper dive into certain tax planning issues in a convenient Q&A format.
The investment income tax is an additional 3.8 percent tax that is imposed upon the lesser of the following amounts:
(1) Net investment income; or
(2) The excess (if any) of (i) the taxpayer’s adjusted gross income (AGI) for the year over (ii) the applicable threshold amount.
The threshold amount for single taxpayers is $200,000. For married taxpayers filing a joint return, the threshold is increased to $250,000.
Example: Erica and Mickey are a married couple with earnings of $400,000 and net investment income equal to $125,000 for 2013. Their AGI, therefore, exceeds the threshold level for married taxpayers by $150,000. Because $125,000 is less than the $150,000 by which their income exceeds the threshold, the tax applies to all of their net investment income. In 2014, Erica and Mickey have earnings of only $300,000 and net investment income of $125,000. Because their AGI only exceeds the threshold by $50,000 in 2014, the tax applies to the $50,000 excess. Their $125,000 in net investment income is not subject to the tax in 2014.
Q: What is net investment income?
The investment income tax is a 3.8 percent tax on “net investment income” that is added to any tax that certain high income taxpayers would otherwise owe on such income. The tax applies for tax years beginning after December 31, 2012.
The tax is imposed on a taxpayer’s “net investment income” or a portion of the taxpayer’s adjusted gross income (AGI). In general, net investment income encompasses income that is considered to be “unearned,” and is defined in IRC Section 1411 to include the sum of the following three categories of income:
(a) gross income from interest, dividends, annuities, rents and royalties that is not derived in the ordinary course of the taxpayer’s trade or business;
(b) income derived from a trade or business involving a passive activity of the taxpayer or trading in financial instruments or commodities; and
