While the thresholds for the 3.8% net investment income tax (NIIT) have remained unchanged since the NIIT went into effect in 2013, taxpayer incomes have generally grown significantly. So more taxpayers are getting hit with this additional tax. The NIIT applies to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds the applicable threshold. And it kicks in long before the top short- and long-term capital gains rates apply. We can help you manage potential NIIT exposure. Contact us at (636) 532-9100.
