Yes — work-study does take out taxes, but not all of them. Your school withholds federal income tax (and state income tax, where it applies) from every work-study paycheck the same way any employer would. What usually doesn’t come out is the 7.65% for Social Security and Medicare, because student employees working for their own school qualify for a special FICA exemption. And because most work-study earnings fall well below the standard deduction, a lot of students get every withheld dollar back at tax time.
What Gets Withheld From Each Paycheck
Your school’s payroll office treats work-study wages like any other wages for income tax purposes.1Federal Student Aid. The Federal Work-Study Program The fact that the job is funded through financial aid changes nothing on the payroll side. Federal income tax comes out. If your state has an income tax, that comes out too.
Before your first shift you’ll fill out Form W-4, which tells payroll how much federal tax to withhold from each check. Your filing status, whether someone else claims you as a dependent, and whether you hold another job all feed into the calculation.2Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
Claiming Exempt on Your W-4
A lot of work-study students can skip federal income tax withholding entirely by writing “Exempt” on their W-4. You qualify if you had no federal income tax liability last year and expect none this year.2Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate For a student whose only income is a modest work-study paycheck, that’s often the case. The upside: more money in each check, no refund to chase later.
Two catches. Claiming exempt only affects income tax; it doesn’t change Social Security or Medicare withholding. And the exempt claim expires annually. If you claim it, submit a new W-4 by mid-February of the following year or payroll will revert to the default rate.
Why Social Security and Medicare Usually Aren’t Withheld
Under federal law, wages you earn working for the school where you’re enrolled are exempt from Social Security tax (6.2%) and Medicare tax (1.45%) as long as you’re regularly attending classes.3Office of the Law Revision Counsel. 26 USC 3121 – Definitions That’s the 7.65% that would otherwise vanish from a typical part-time paycheck. On $3,000 of semester earnings, keeping the FICA exemption is worth about $230.
The rule rests on the idea that your primary relationship with the school is educational rather than employment-based. The IRS safe-harbor test generally requires at least half-time enrollment during the academic term, and payroll checks enrollment each term to confirm the exemption still applies. Students in their final semester who are enrolled in fewer credits than usual can still qualify if they’re taking whatever hours are needed to finish the degree.4Internal Revenue Service. Revenue Procedure 2005-11
When FICA Does Come Out
The exemption disappears in a few common situations, and the one that surprises students most is summer work.
- Working during a break longer than five weeks without being enrolled that term. If you stay on campus over the summer and aren’t taking summer classes, FICA will be withheld from those paychecks. Shorter breaks like winter and spring are fine as long as you were a qualifying student the prior term and plan to enroll the next one.4Internal Revenue Service. Revenue Procedure 2005-11
- Enrollment dropping below half-time during a regular semester. From that point forward, the school must start withholding FICA.5eCFR. 26 CFR 31.3121(b)(10)-2 – Services Performed by Certain Students in the Employ of a School, College, or University
- Off-campus placements where the outside organization controls and directs the work. The FICA exemption only covers work in the employ of a school, and whether the school or the off-campus employer counts as your employer depends on the terms of their agreement.1Federal Student Aid. The Federal Work-Study Program
- Being classified as a full-time employee rather than a student worker. In that case the exemption doesn’t apply regardless of your enrollment.4Internal Revenue Service. Revenue Procedure 2005-11
If you want to preserve the FICA benefit through the summer, enroll in summer classes that keep you at half-time. Otherwise, plan on seeing Social Security and Medicare deductions on those checks.
International Students on F-1, J-1, or M-1 Visas
International students get a broader FICA exemption than the general student rule. A separate provision of federal law exempts nonresident aliens temporarily in the U.S. under these visa categories from Social Security and Medicare taxes, as long as the work relates to the purpose of the visa.3Office of the Law Revision Counsel. 26 USC 3121 – Definitions The exemption generally covers the first five calendar years in the U.S. and applies to on-campus work up to 20 hours per week during the academic year and 40 hours during summer.6Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes
After five calendar years, students who meet the substantial presence test become resident aliens for tax purposes. The broad visa-based FICA exemption ends at that point, though the regular student employee FICA exemption may still apply if they’re enrolled at least half-time at the school where they work.6Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes Students from countries with U.S. tax treaties may also be able to reduce or eliminate federal income tax withholding on their wages, but not every treaty includes a wage exemption. Check with the school’s international tax office before assuming you qualify.
Will You Actually Owe Anything?
Whether you owe federal tax depends on your total income for the year, not just work-study. For 2026, the standard deduction for a single filer is $16,100.7Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If your total stays below that, you’ll likely owe nothing in federal income tax. Most work-study positions pay well under the threshold.
If a parent or someone else claims you as a dependent, your standard deduction is generally limited to your earned income plus a small additional amount, capped at the full $16,100.8Internal Revenue Service. Publication 501, Dependents, Standard Deduction, and Filing Information In practice a dependent student whose only income is wages still won’t owe federal tax as long as those wages come in under $16,100, because the deduction grows with earned income.
Owing nothing is not the same as getting nothing back. If any federal or state income tax was withheld from your paychecks, filing a return is the only way to get that money back.9Internal Revenue Service. Tax Information for Students A student who earned a few thousand dollars during the school year with $200 withheld is leaving that $200 on the table by skipping the return. Most students can file for free through IRS Free File or a campus volunteer tax assistance program.
This is also the case for claiming exempt on your W-4, if you legitimately qualify. Claiming exempt when you truly expect no tax liability spares you the withhold-then-refund cycle.
Work-Study Earnings and Next Year’s Aid
One boundary worth knowing, because the concern comes up often: earning money through work-study doesn’t shrink your financial aid the following year. Federal Work-Study earnings are excluded from the income calculation your school uses to determine your aid package.10Federal Student Aid. 8 Things You Should Know About Federal Work-Study The wages still appear on your tax return and on the FAFSA, but when you report them in the designated field, the formula subtracts them out. Wages from a non-work-study campus job or an outside employer don’t get the same treatment.
