Part-Time Student Job: Do I Owe Taxes?

If you are a student working part-time and your total income for 2026 is below the standard deduction ($16,100 for single filers), you will not owe federal income tax. However, Social Security (6.2%) and Medicare (1.5%) are still withheld from every paycheck regardless of how little you earn. This article explains the filing threshold, when students must file, and how to recover any withheld income tax.

The filing threshold explained

The federal filing threshold for a single filer in 2026 is $16,100 - the standard deduction. If your gross income is at or below this amount, your taxable income is zero, which means your federal income tax liability is also zero. You cannot owe tax on zero taxable income.

This threshold applies to your total income for the year, not just your income from the part-time job. If you have other income - interest, freelance work, investment gains - it all counts toward the threshold.

For 2026, the standard deductions by filing status are:

• Single: $16,100
• Married Filing Jointly: $32,200
• Head of Household: $24,150

When students must file

You are required to file a federal return in 2026 if any of these apply:

• Income above the standard deduction: Your gross income exceeds $16,100 (single). Even if you end up owing nothing, you must file once you cross the threshold.
• Self-employment net income above $400: If you babysit, tutor, freelance, or run any side business and net more than $400, you must file regardless of your total income level. Self-employment tax (which covers both employee and employer FICA shares) applies from the first dollar above $400.
• Special situations: Receiving an advance premium tax credit, owing household employment taxes, or certain other conditions can also require filing even below the income threshold.

You are not required to file if your income is below the threshold and none of the special situations apply - but you should still file if income tax was withheld from your paychecks. See the next section.

FICA still applies below the threshold

Here is the part many students miss: the filing threshold only applies to income tax. FICA taxes - Social Security and Medicare - have no standard deduction, no threshold, and no exemption for low earners (with one exception, covered below).

On every paycheck from a regular employer, 6.2% goes to Social Security and 1.5% goes to Medicare. That is a combined7.7% taken before you see a dollar, starting from your very first paycheck.

Example: A student earns $8,000 over the summer. No federal income tax is owed (well below the $16,100 threshold). But FICA is still due:

• Social Security: $8,000 x 6.2% = $496.00
• Medicare: $8,000 x 1.5% = $116.00
• Total FICA withheld: $612.00

This $612.00 in FICA cannot be recovered through a tax return (unless the student FICA exemption applies).

How to get withheld taxes back

Even if you are not required to file, you should file a return if your employer withheld federal income tax from your paychecks. Because your taxable income is below $16,100, your actual income tax liability is zero - meaning every dollar withheld for federal income tax comes back to you as a refund.

The process is straightforward:

1. Receive your W-2 form from your employer (typically mailed by January 31).
2. File a federal Form 1040 reporting your income and claiming the standard deduction.
3. Your taxable income will be zero (or negative, which is treated as zero).
4. The IRS refunds the full amount of federal income tax withheld.

Do not skip this step. Employers sometimes withhold income tax even on wages well below the filing threshold, because payroll systems annualize your earnings and may overestimate your annual income. Filing takes under an hour with free IRS Free File software and you get your money back.

Note: FICA taxes withheld (Social Security and Medicare) are not refunded through your return. Those go directly into the FICA system and do not come back via Form 1040.

The student FICA exemption

There is one significant FICA exception for students. Under IRC Section 3121(b)(10), students who are enrolled at least half-time and work for the university they attend are exempt from FICA withholding on those specific wages.

This exemption covers:

• Student workers in dining halls, libraries, and administrative offices at their university
• Teaching assistants (TAs) employed by their own school
• Research assistants (RAs) employed by their own school

This exemption does not cover:

• Jobs at off-campus employers (restaurants, retail, etc.)
• Work at a different school than the one you are enrolled in
• Students who are not enrolled at least half-time during the pay period
• Full-time professional employees who happen to be enrolled in a class

If the exemption applies, your university payroll should not withhold Social Security or Medicare. If you see FICA withheld on wages that should qualify, ask your payroll office to review your status. Correcting an error may require filing Form 843 for a refund of incorrectly withheld FICA.

Dependent vs. independent student

Whether someone else claims you as a dependent affects your standard deduction and filing threshold. If your parents (or someone else) can claim you on their return:

• Your standard deduction is limited to the greater of $1,300 or your earned income plus $450 - up to the normal standard deduction cap ($16,100).
• For most students with earned income only, this means your deduction equals your earned income plus $450, which is slightly more than your earned income. The result: a small positive taxable income (or near zero) once you cross $1,300 in earnings.
• Unearned income (interest, dividends, capital gains) above $1,300 may be subject to the "kiddie tax" - taxed at the parent's rate.

If you support yourself and cannot be claimed as a dependent, you get the full $16,100 standard deduction, and the filing threshold is simply that amount.

Not sure whether you are a dependent? IRS Publication 501 has a step-by-step dependency test. Generally, if your parents provide more than half of your financial support and you are a full-time student under age 24, they can claim you.
