The Internal Revenue Service (IRS) is the U.S. government agency that collects taxes. As a nonresident F-1 or J-1 student, you need to file forms each year with the IRS, even if you earned no income. It is your individual responsibility to understand and meet your tax obligations. Generally, tax returns are due every April 15th based on earnings from the previous year, though there are exceptions to this deadline.

While employers do deduct money from your paycheck throughout the year and send it to the IRS, it may not equal the exact amount owed at the end of the year. If too much was deducted, you may be eligible for a refund. Or, perhaps not enough was deducted, and you will owe more. Salary from a job is not the only kind of earning taxed; many types of income are taxable. Even if you did not work and do not owe any taxes, you may need to submit an informational form to the IRS.

 Form 8843 is not an income tax return. Form 8843 is merely an informational statement required by the U.S. government for certain nonresident aliens (including the spouses or dependents of nonresident aliens).  Nonresident aliens who are not required to file an income tax return (Form 1040NR or Form 1040NR-EZ), but who are required to file Form 8843, need not apply for a Social Security number (SSN) or an Individual Taxpayer Identification Number (ITIN). If, however, an SSN/ITIN has been assigned, the number must be included on Form 8843.
