The important thing to keep in mind is that different rules will apply to income earned during the different time periods (resident and non-resident status). Though we can’t cover these rules exhaustively here, we’ll lay out the ground rules and key concepts that you should be familiar with.

The key principles of dual-status taxation:

For the part of the year that you are a US resident, you will be taxed on income from all worldwide sources
During the nonresident portion of a year, you will be taxed on certain US-sourced income only, including, but not limited to:
- Income that is effectively connected with a U.S. trade or business
- Certain types of income which are not effectively connected to a US trade or business. (More on Effectively Connected Income (ECI) and FDAP below.)
US-sourced income is potentially taxable whether you are resident or nonresident unless a specific exclusion, exemption, or treaty rule applies to your case.
ECI is generally taxed at normal graduated (progressive) tax rates.
FDAP income earned by non-residents is taxed at a flat 30% rate (unless reduced by statute or tax treaty).

Effectively Connected Income (ECI)

The “hard part” of determining your tax obligation in a dual-status scenario is generally identifying which portions of income are U.S.-sourced. The IRS applies a principle called “effectively connected income” to determine which income sources are considered to be “connected” to the U.S. ECI is a category mainly applied to nonresident aliens (and foreign corporations) to determine which income will be taxed on a net basis at graduated rates.

Depending on your tax bracket and financial asset position, ECI tax rates may be more favorable than the flat 30% rate for nonresident FDAP income. It’s important to remember that generally only nonresident aliens or foreign corporations can receive effectively connected income.

If you engage in any trade or business in the United States, all U.S.-sourced income connected with the conduct of that trade or business is considered to be ECI.

Common examples of ECI include:

Compensation for personal services performed in the United States
Partnership income connected with a U.S. trade or business
Certain types of U.S.-sourced rental income
Gains from sale or exchange of U.S. real property assets
If you are a student on an F/M/J/Q visa, the taxable portion of any scholarship you receive is treated as ECI

Notably, trading stocks, securities, or commodities through a U.S. broker or other agent does not, by itself, cause the related income to be treated as ECI.

Certain types of income which are normally treated as FDAP income can instead become ECI if it passes either of the following tests:

The Asset-Use Test: the income must be associated with assets used in the conduct of a U.S. trade or business.
The Business Activities Test: the activities of a trade or business conducted in the U.S. are a material factor in the realization of the income

More details on ECI can be found on the IRS Website.

Fixed, Determinable, Annual, or Periodical Income (FDAP)

FDAP generally refers to certain fixed or determinable, annual or periodical income such as interest, dividends, pensions, annuities, scholarship and fellowship grants, and some other types of compensation, to the extent that they are not treated as ECI.

FDAP is taxed at a flat 30% rate (unless lowered by a tax treaty).

Generally, FDAP is any income which is:

Not ECI
Not derived from the sale of real or personal property
Not a type of income exempt from gross income (e.g. tax-exempt municipal bonds or qualified scholarship income)

FDAP and Capital Gains dual-status taxpayer

Whether or not your capital gains are subject to the flat 30% tax rate depends on how many days you were in the U.S. during a given tax year:

For individuals who were in the U.S. for 183 days or more in a given year, income derived from sales or exchanges of capital assets are taxed at the 30% FDAP rate.
For individuals who were in the U.S. for less than 183 days, capital gains are generally not taxed unless they are classified as ECI.

Note: Many tax treaties specifically reduce or eliminate capital gains taxation.

A full list of examples and classifications of FDAP can be found on the IRS website.

Restrictions and Limitations

Some unique restrictions apply to those applying for dual status tax returns. We’ve listed the most important ones below. A complete list can be found here.

Dual status filers cannot use the standard deduction on IRS Form 1040 (but certain deductions can be itemized), unless married to a U.S. citizen or resident and electing to be taxed as a full-year resident.
You cannot use the head of household tax schedule
You cannot take any deductions against non-ECI earned during periods of nonresidence
You cannot file a joint return, unless you are married to a U.S. citizen or resident
If you are a nonresident married to a U.S. citizen and you choose not to file jointly, you must file as married filing separately
If you are a nonresident, married to a U.S. citizen, and not filing jointly, you are ineligible for: dual-status taxpayer

It’s no exaggeration to say that tax preparations for dual-status situations can get very complicated – there are a huge number of factors to consider. Planning ahead and working with a qualified professional tax advisor to develop an effective strategy for your dual-status transition could potentially save you a lot of time and ensure compliance while potentially reducing your overall tax burden.
