U.S. Income Tax Basics
Most international visitors living in the United States are required to file annual income tax returns. U.S. tax law is very complex. Here is a brief summary of what you need to know.
U.S taxes are pay-as-you-go.
This means you need to pay most of your tax during the year.
You pay as you receive income, rather than paying at the end of the year. The tax year is a normal calendar year—from January 1 to December 31.
In most cases, taxes are withheld from your income throughout the year. Cornell University and other employers are required to take money out of your paycheck for taxes and send it to the tax collection agency. By March 15, Cornell reports wages, scholarships, and tax withheld during the previous year and sends you a statement.
Each Cornellian’s tax situation is unique.
Your situation depends on the amount of time you’ve spent in the United States, the visa statuses you’ve held, the type of income you receive, and your nationality. Find out if your country has a tax treaty with the United States.
The deadline for filing your 2020 tax returns has been extended to May 17, 2021, for both federal and New York State taxes. The deadline is usually April 15, for both federal and New York State taxes.
You pay taxes on U.S. income earned in the previous calendar year.
Your tax return is a form you fill out that accounts for the difference between taxes already withheld and tax you still owe. Sometimes you get a refund, and other years you may owe the government money. If you’re a nonresident for federal tax purposes, you need to file a nonresident tax return.

How do I know if I need to file a U.S. federal tax return?
If you received any U.S. income—wages, a fellowship for living expenses, or a travel grant, for example—you will need to file some U.S. tax forms. Our Sprintax software will select which forms you need to file based on how you answer several initial questions.
If you did not receive any income in the United States during the tax year, you do not need to file a tax return, but you’re obligated to send one form to the IRS. Sprintax will help you file the required form 8843.
What kinds of income are taxable?
- Scholarships, fellowships, or grants from a U.S. source that exceed the amount of tuition and mandatory fees
- Wages from any U.S. job, on-campus or off-campus, including a teaching or research assistantship
- Consulting fees for work done in the United States
- Dividends or capital gains from U.S. mutual funds, stocks, or bonds
- Any other income—such as rent or copyright earnings—from U.S. sources, except for interest earned on a U.S. savings account or certificate of deposit
I'm worried about my withholdings. What should I do?
Many nonresident students, scholars, and researchers do not have to contribute to Social Security and Medicare during their first five years in the United States. Find out if you qualify for this exemption.
If you are exempt, you can show the IRS webpage to your employer and ask for a refund, or you can wait until you file your taxes. You’ll receive a refund from the IRS.
