The net investment income tax, which applies for the first time from Jan 1 2013, imposes a rate of 3.8 percent to certain net investment income of individual estate and trusts that have income over certain amounts. The US/UK treaty, does not give US persons residing outside of the US protection against this amount, nor does a foreign tax credit apply.
Individuals will owe this tax if they have Net Investment Income and also have modified adjusted gross income over the following thresholds:
| Filing Status | Threshold Amount |
|---|---|
| Married filing jointly | $250,000 |
| Married filing separately | $125,000 |
| Single | $200,000 |
| Head of household (with qualifying person) | $200,000 |
| Qualifying widow(er) with dependent child | $250,000 |

As a general rule, such deductions must be “properly allocable” to items of gross investment income.
