On Jan. 1, German citizen Hans Schlabaugh arrived in the United States for business meetings. He returned to Germany 10 days later. Then, on May 15, Schlabaugh traveled to the U.S. again, this time on a visa to work for the American division of his employer for the remainder of the year.
For tax purposes, the Internal Revenue Service considers Schlabaugh a U.S. nonresident alien until May 15. After May 15, he is considered a U.S. resident alien. Will this affect the tax forms Schlabaugh will file for that tax year?
In a word: Yes. He'll need to file federal income taxes as a dual-status alien, which recognizes a person as a U.S. resident alien and a U.S. nonresident alien in the same tax year. Typically, this occurs the year a non-U.S. citizen arrives in or departs from the U.S., as long as certain residency requirements are met.
Being a dual-status alien shouldn't be confused with citizenship, though. It only applies to federal taxes. It signifies that a person will need to follow different tax rules for portions of the same year, depending on the amount of time he or she is a U.S. resident alien versus a U.S. nonresident alien [source: IRS].
Certain people, although they may meet the criteria for dual-status aliens, are exempt. This includes teachers, trainees, students and people temporarily in the U.S., such as professional athletes or foreign government workers.

10: Pass the Resident Alien IRS Test
You're not a U.S. resident, but your work necessitates that you to live in America for a significant period of time, probably several months. This may sound like a simple enough scenario for figuring out your income taxes, but there's an important test that will eventually factor into the mix.
Before you break out the calculus primer or hire a tutor, take heart. This test doesn't require any studying. In fact, it may be one of the easiest tests you'll ever take. It simply tracks the time you've spent in the United States.
You'll pass the test, known as the Resident Alien Test, if you've established a "substantial presence" in the U.S. This means you have spent more than 31 days in the U.S. during the current tax year or more than 183 days during a three-year period that includes the current tax year.
You'll also meet the requirements of the Resident Alien Test if you become a permanent resident of the U.S. but do not have citizenship or are in the process of applying for citizenship. In this case, the Resident Alien Test applies to someone who, for example, has a green card that allows him or her to resident and work in the U.S. lawfully [source:Investopedia].

9: Pass the Nonresident Alien IRS Test
If you are not a citizen of the U.S., but are in the U.S., you may be considered a nonresident alien, according to the IRS. Unlike a noncitizen who passes the Resident Alien test, which involves a green card and a days-spent-in-country threshold, the Nonresident Alien Test requires neither of these criteria. In fact, the opposite is true.
A nonresident alien earns the classification when they reside in the U.S. without a green card. A green card is the colloquial term for the Alien Registration Card, which signifies that a nonresident is lawfully in the U.S. as a permanent or conditional resident. It allows a nonresident to work in the U.S., and travel back and forth between the U.S. and other countries [source: Bray]. If a noncitizen does not qualify for a green card, that person is considered a nonresident alien.
In addition, if a person who is not a U.S. resident does not show "substantial presence" in the U.S. — by living in America for 31 days in the current year or 183 days during a three-year period that includes the current year — then that person is considered a nonresident alien [source: Investopedia].
When a person is a nonresident alien and a resident alien in the same year, he or she will follow different tax rules according to the difference in alien status. It's important to understand the differences between resident alien taxes and nonresident alien taxes, which we'll begin outlining on the next page.
8: Understand Resident Alien Taxes
When a noncitizen of the U.S. is classified as a U.S. resident alien, that person is subject to specific taxation on income. In general, a resident alien will be taxed on personal income in the same way a U.S. citizen is taxed.
This means a resident alien will need to include all forms of income — interest, dividends, wages or other compensation for services — when filing federal income taxes. A resident alien also will need to include income from rental property, royalties or any other type of income on his or her taxes. And this goes for income earned in any other part of the world, too. Worldwide income should be included when filing U.S. federal income taxes.
Because resident aliens are taxed the same way U.S. residents are taxed, resident aliens will be taxed on income according to the graduated tax rates determined by the IRS. These gradated tax rates, known commonly as tax brackets, range from 10 percent on taxable income of $9, 075 or less to 39.6 percent on taxable income of $406,750 or more [sources: Erb, IRS].
7: Understand Nonresident Alien Taxes
In most cases, nonresident aliens will need to file federal income taxes in the United States. Specifically, nonresident aliens who earned income that exceeded the personal exemptions allowed by the IRS, who received money from an estate or trust, or who are charged with the care of a nonresident alien, will be required to withhold federal income tax and file federal income taxes at the end of the tax year.
There is one important exception. Nonresident aliens need only to claim sources of income that originated in the United States.
To complicate matters, there are exceptions to the exception. Certain investments, like stocks, could still be subject to tax. For example, if you live in Saudi Arabia and own a company that operates in the U.S., but you are a nonresident alien of the U.S., the income you receive from the business could be subject to U.S. tax. Dividends like these would be taxed at 30 percent for a nonresident alien, unless they are capital gains received from the sale of a business or property, at which point the money is exempt until a certain threshold — usually $250,000 [sources: IRS, Investopedia, Pomerlau].
6: Claim Tax Credits When You Can
For the part of the tax year a person is considered a resident alien, he or she can generally claim the same tax credits that apply to U.S. citizens. After all, a resident alien is withholding taxes according to the same rules and regulations that apply to U.S. citizens, too.
As long as a resident alien meets the criteria for each credit, he or she is typically able to claim credits such as a Child Tax Credit, Earned Income Credit, Adoption Credit, Child and Dependent Care Credit and Credit for the Elderly and Disabled [source: IRS].
Plus, a resident alien can claim foreign tax credits, unlike a nonresident alien. A foreign tax credit is designed to avoid double taxation by the U.S. and another country. Often, if the tax rate in another country is higher than in the U.S., there won't be a U.S. tax levied on foreign income. If, however, the tax rate in another country is lower than in the United States, the U.S. tax will only be applicable to the difference between the two tax rates. Keep in mind, however, that the credit can only be used to reduce U.S. taxes on income that originates in another country. It cannot be used to reduce U.S. taxes on U.S. income [source: IRS].
