Graduate School Taxes: Stipends, Fellowships, and the 1098-T
How graduate student stipends, fellowships, and tuition waivers are taxed — and what first-gen students need to know to file correctly and avoid surprises.
The Surprise No One Warns You About
Most first-gen graduate students arrive in their programs expecting taxes to work like undergraduate employment — the university withholds, you file, and nothing is owed at the end. Stipends do not work that way. Your university deposits the full stipend amount with zero withholding, and you owe federal and state income taxes on it come April.
The solution is quarterly estimated tax payments — small amounts paid in April, June, September, and January that prevent a single large bill at filing time. Missing this in year one is the most common first-gen financial miscalculation in doctoral programs. This guide covers everything you need to know.
Stipends vs. Fellowships: What Is Taxable
The IRS distinguishes between fellowship income used for qualified education expenses (tuition, required fees, books required by the course) and fellowship income used for living expenses. The first category is not taxable. The second category is — regardless of whether the university issues a W-2 or calls the payment a "fellowship," "stipend," or "graduate assistantship."
Practically: the portion of your funding that covers your tuition waiver is not taxable. The portion that lands in your bank account for living expenses is taxable. Keep records of how your funding package is structured — your offer letter and the graduate school's financial aid documentation should spell this out.
The 1098-T (Tuition Statement) reports both tuition and scholarship amounts to the IRS. When Box 5 (scholarships received) exceeds Box 1 (qualified tuition billed), the difference is potentially taxable. This is common for PhD students with full tuition waivers — the scholarship amount shown is large, but most of it offsets tuition directly and is not cash in your pocket. Your university's graduate school tax resources or a VITA volunteer can help you reconcile the form correctly.
Quarterly Estimated Tax Payments
If your taxable stipend income exceeds $1,000 annually and your university does not withhold, you are required to make quarterly estimated payments. The IRS payment schedule: April 15, June 15, September 15, January 15 of the following year. Pay using IRS Form 1040-ES or online at IRS Direct Pay.
A practical estimate for a single filer in the 12% federal bracket: multiply your annual taxable stipend by 0.12, then divide by 4. Add Massachusetts state tax at 5% of your annual stipend divided by 4 if you are in MA. The IRS underpayment penalty is typically 4 to 6% of the shortfall — small, but the habit of quarterly payments protects you from both the penalty and the cash-flow shock of a lump-sum April bill.
Many graduate students in their first year simply miss these payments and pay the penalty at filing — it is survivable. But planning ahead is the better path.

Leadership Brainery's Tax Resource List
We distribute a one-page tax checklist to all new fellows in September — covering estimated payments, 1098-T interpretation, and MA state filing — so the first April filing is not a surprise. Ask during monthly sessions for the current year's checklist.
Frequently Asked Questions
Is a PhD stipend taxable income?+
Yes. Graduate stipends are taxable income under US federal law — they are reported on your tax return even though they are typically not reported on a W-2 (since they are not wages in the traditional employment sense). Most universities do not withhold federal income tax from stipend payments, which means PhD students receive their full stipend but owe taxes on it at filing time. This is one of the most common first-gen financial surprises in the first year of graduate school — planning for a quarterly estimated tax payment prevents a large bill in April.
How are graduate fellowships taxed differently from stipends?+
Fellowships used for tuition and required fees are not taxable. Fellowships used for living expenses (room, board, transportation, personal expenses) are taxable — even if the university calls it a 'fellowship' and issues no W-2. The distinction is what the money is used for, not what it is called. If your fellowship covers both tuition and living expenses, only the living expense portion is taxable. Keep records of how each dollar of fellowship income was used.
What is a 1098-T and do graduate students receive one?+
The 1098-T (Tuition Statement) reports tuition and scholarship/fellowship amounts to the IRS. Graduate students at universities with tuition waivers often receive a 1098-T showing tuition billed and scholarships received. The form can be confusing: if Box 5 (scholarships) exceeds Box 1 (qualified tuition), the difference may be taxable. Many graduate students mistakenly believe the 1098-T means they owe nothing — it is a reporting document, not a tax clearance. Consult your university's financial aid or graduate school tax resources for field-specific guidance.
Should graduate students make estimated tax payments?+
Yes, if your annual taxable income exceeds $1,000 and your university does not withhold taxes from your stipend. The IRS requires quarterly estimated tax payments (due April, June, September, January) from anyone whose tax liability is not covered by withholding. Underpaying estimated taxes results in a penalty — typically small but avoidable. Use IRS Form 1040-ES to estimate. A rough calculation: multiply your annual taxable stipend by 12% (single filer in the 12% bracket) and divide by 4 to find your quarterly payment.
Do I owe state income taxes on my stipend?+
Most states with income taxes tax PhD stipends — Massachusetts (where most Leadership Brainery fellows are enrolled) taxes stipend income at 5%. This state tax is also typically not withheld from stipend payments, so Massachusetts graduate students owe both federal and state estimated payments. Check your state's department of revenue for graduate stipend guidance — some states have specific exclusions for fellowship income.
Where can graduate students get free tax help?+
Free tax preparation resources for graduate students: IRS Free File (income under $73,000); VITA (Volunteer Income Tax Assistance — free for income under $67,000, run by IRS-certified volunteers at many universities and community organizations); your university's graduate school may offer a tax workshop specifically for international and domestic graduate students in January or February; the Grad Student Union at many universities publishes a tax guide each year. Never pay a commercial tax preparer for a stipend-only return — the return is straightforward and free resources handle it correctly.
