Someone in your university's international student group mentioned a "tax treaty exemption." A few students from China say they get $5,000 of their income tax-free. Your Indian classmate says there's nothing for her. And your friend from Nepal has never heard of any of this. All three of them are right, but for completely different reasons.
Quick answer: China has a favorable student tax treaty with the US that exempts up to $5,000 of student income per year. India has a tax treaty with the US, but it offers very limited benefits for F-1 students, primarily for business income, not wages. Nepal has no tax treaty with the US at all, meaning Nepali students pay full federal income tax rates with no treaty-based reduction. This guide breaks down exactly what applies to you by country.
What You Need to Know First
A tax treaty is a bilateral agreement between the US and another country designed to prevent double taxation: paying income tax to two governments on the same income. The US has tax treaties with about 68 countries. Each treaty is different and contains specific articles covering different types of income and taxpayers.
For F-1 students, the most relevant treaty provision is typically the student/trainee article: a clause that exempts certain income earned by students from the treaty country who are studying in the US. Not all treaties include this. And even among those that do, the dollar amount, duration, and type of income covered varies significantly.
Two critical concepts:
Saving clause: Most US tax treaties contain a saving clause that says the US can still tax its own residents regardless of the treaty. As a non-resident alien F-1 student, the saving clause generally doesn't apply to you, which is why treaty benefits are most powerful during your NRA years.
Non-resident alien requirement: Most student treaty benefits only apply while you are a non-resident alien. Once you become a resident alien (after 5+ calendar years on F status), treaty benefits under the student article typically expire. Read our guide on OPT STEM extension tax filing rules.
⚠️ Verify before filing: Tax treaties are legal documents subject to renegotiation, IRS interpretation updates, and congressional modifications. Always confirm current treaty provisions at IRS.gov or through IRS Publication 901 (US Tax Treaties) before claiming a benefit.
China: The $5,000 Student Income Exemption
The US-China Tax Treaty, Article 20 provides the most generous student tax benefit available to any F-1 student group. Chinese students and trainees studying in the US can exclude up to $5,000 per year of US-sourced income from federal taxation.
Who qualifies:
- You are a resident of China (People's Republic of China) immediately before coming to the US
- You are present in the US primarily to study or obtain training
- You are in F-1, J-1, M-1, or similar student/trainee status
- The income is from employment or self-employment in the US
What counts as covered income:
- Wages from an on-campus job
- CPT wages
- OPT wages
- Research stipends (may vary: check with your DSO or tax advisor)
What the $5,000 exemption means in practice: If you earn $30,000 in your first year of OPT, only $25,000 is subject to federal income tax. At an effective NRA tax rate of around 12–15%, that's roughly $600–$750 saved per year.
Duration: Article 20 of the US-China treaty does not have a hard expiration year: it can apply for "a period not exceeding 5 years" from your first arrival for most interpretations, though IRS guidance has historically allowed it for as long as you remain a non-resident student or trainee. Consult IRS Publication 901 and a tax advisor for your specific situation.
Does it apply on STEM OPT? Generally yes, as long as you're still an NRA (within your 5 exempt calendar years). Once you become a resident alien, the saving clause in the treaty prevents you from claiming the Article 20 benefit.
How to Claim the China Treaty Exemption on Your Tax Return
Option 1: Claim on Form 1040-NR at filing time
- On your 1040-NR, report your full wages on Line 1a
- Then claim the treaty exemption on Schedule OI, Item L: enter "China," "20," and the amount you're excluding (up to $5,000)
- The excluded amount reduces your taxable income
Option 2: Claim at source using Form 8233
- Fill out Form W-8BEN or Form 8233 (depending on income type) and submit to your employer
- Your employer then withholds federal income tax on only the amount above $5,000
- This is more efficient: your withholding reflects the exemption throughout the year rather than waiting for a refund at tax time.
Sprintax handles the Form 1040-NR treaty claim automatically when you select China as your country of residence.
⚠️ W-4 note: If you submit Form 8233 to your employer, do not also submit a W-4. For NRAs claiming treaty benefits at the source, Form 8233 replaces the W-4 for the treaty-covered portion of income.
India: Limited Treaty Benefits for F-1 Students
The US-India Tax Treaty exists: it was signed in 1989 and covers various types of income. However, it offers very little benefit to F-1 students with wage income.
The student/trainee article (Article 21) in the US-India treaty covers students and business apprentices. However, the income exemption is narrow: it primarily applies to payments received from abroad (from Indian sources) specifically for maintenance, education, or training, not to wages earned in the US from a US employer.
What this means practically:
- If your parents in India send you money to pay your tuition: that transfer is covered and not subject to US tax (it's a gift/support payment, not income anyway)
- If you earn a salary from your US employer on OPT or CPT: the treaty Article 21 does not exempt this income.
The real-world bottom line for Indian F-1 students: The US-India treaty provides almost no benefit for the wages, stipends, and OPT income that most F-1 students actually care about. You pay the same federal income tax rates as any other NRA.
Where the India treaty does help:
- Dividend income: Article 10 of the US-India treaty caps withholding on dividends at 15–25% (rather than the default 30% for NRAs), which may be relevant if you hold Indian or US stocks that pay dividends
- Royalties and technical services: Article 12 covers certain royalty income at reduced rates, rarely relevant for students.
If you have investment income or dividend income, consult a tax professional about whether the India treaty helps your situation. For wage income from a US job, it doesn't.
Nepal: No Tax Treaty with the United States
Nepal does not have a tax treaty with the United States. Full stop.
Nepali F-1 students pay federal income tax at the standard NRA graduated rates with no treaty reduction of any kind. There is no exemption for wages, no reduced rate on dividends, and no student income exclusion.
| Country | Tax Treaty | Student Wage Exemption | Practical Benefit for F-1 |
|---|---|---|---|
| China | ✅ Yes (1984) | ✅ $5,000/year | High: saves $600–$750+/year |
| India | ✅ Yes (1989) | ❌ No (wages) | Low: no benefit on OPT wages |
| Nepal | ❌ None | ❌ No | None |
| South Korea | ✅ Yes (1979) | ✅ $2,000/year | Moderate |
| Philippines | ❌ None | ❌ No | None |
| Mexico | ✅ Yes (1993) | ⚠️ Limited | Low |
| Bangladesh | ❌ None | ❌ No | None |
| Pakistan | ❌ None | ❌ No | None |
For students from non-treaty countries, the only tax reduction tools available are: correct NRA withholding, FICA exemption, legitimate deductions available to NRAs (limited), and ensuring you're not over-withholding throughout the year.
What NRA Tax Rates Actually Look Like Without a Treaty
For students from Nepal, India (on wages), and other non-treaty countries, here's what federal income tax looks like on a typical OPT salary for tax year 2025:
| Taxable Income | Federal Tax Rate (NRA) | Approximate Tax |
|---|---|---|
| $0–$11,925 | 10% | Up to $1,193 |
| $11,926–$48,475 | 12% | $1,193 + 12% above $11,925 |
| $48,476–$103,350 | 22% | Prior + 22% above $48,475 |
| $103,351–$197,300 | 24% | Prior + 24% above $103,350 |
NRAs cannot claim the standard deduction (generally). This means your taxable income is your gross income minus only the specific deductions available to NRAs (state income taxes paid, certain charitable deductions). The absence of the $14,600 standard deduction means NRAs effectively pay more tax than a resident at the same income, which is one reason treaty benefits matter so much for Chinese students.
How to Know If Your Country Has a Treaty
Check IRS Publication 901 (US Tax Treaties): it's a free PDF on IRS.gov and lists every country with which the US has a tax treaty, along with the specific articles and rates.
For a quick lookup: search "IRS tax treaty [your country]" to find the treaty summary. The student/trainee article is what you're looking for: it's usually Article 20 or 21 in most treaties.
If your country has a treaty with a student article, you'll see a specific dollar amount and duration stated. If there's no student article, or no treaty at all, you have no wage exemption.
Real Student Scenarios
Priya's situation: Priya earns $65,000 on OPT as a data analyst in Texas. She looked up the US-India treaty and found Article 21. After research, she confirmed it doesn't cover her OPT wages. Her full $65,000 is subject to federal income tax at NRA rates. No FICA (still an NRA). She files 1040-NR with Sprintax, no treaty claim. Federal tax owed: approximately $9,200 after NRA-allowed deductions.
Wei's situation: Wei earns $72,000 on OPT. He claims the Article 20 exemption on Schedule OI of his 1040-NR: $5,000 excluded. His taxable income for federal purposes is $67,000. The treaty saves him approximately $750 in federal tax. His employer was notified via Form 8233 at the start of his OPT, so only $67,000 equivalent was withheld throughout the year. At filing, his withholding matches closely and he receives a small refund.
Sanjay's situation: Sanjay earns $48,000 on OPT in Illinois. No treaty. Full $48,000 is subject to federal tax. He also owes Illinois state income tax (4.95%). He files Form 1040-NR plus Illinois non-resident return via Sprintax. His FICA remains exempt as long as he's still an NRA. No treaty benefit of any kind, but he's correctly exempt from the 7.65% FICA on his wages, which saves him roughly $3,672/year compared to what a US citizen at the same salary would pay in total taxes.
Common Mistakes to Avoid
1. Chinese students not claiming their $5,000 exemption because they didn't know it existed. Fix: Check Schedule OI on your Form 1040-NR. If you're from China and haven't been claiming the Article 20 exemption, you may be able to amend prior-year returns (up to 3 years back) to claim refunds.
2. Indian students assuming the treaty covers their OPT wages because they heard "India has a tax treaty." Fix: The US-India treaty exists but Article 21 covers payments from abroad for education, not US employer wages. Don't claim an exemption that doesn't apply: it can trigger an IRS notice.
3. Nepali and other non-treaty students paying unnecessary federal income tax because their W-4 was filled out incorrectly. Fix: Use Sprintax's free W-4 tool for NRAs to ensure your withholding is calculated correctly. Over-withholding means giving the IRS an interest-free loan: under-withholding means a surprise tax bill in April.
4. Claiming treaty benefits after becoming a resident alien. Fix: Most student treaty benefits under the saving clause disappear once you become a resident alien. If you've crossed the 5-year threshold, don't claim treaty exemptions without confirming they still apply to residents.
5. Not using Form 8233 to claim the China treaty at source, then being confused by a large refund at filing. Fix: Submit Form 8233 to your employer when you start your job. This ensures your withholding reflects the exemption all year, rather than over-withholding and waiting for a refund.
Bottom Line
If you're from China: claim your $5,000 Article 20 exemption every year you're an NRA, either via Form 8233 with your employer or on Schedule OI of your 1040-NR. Amend prior years if you missed it.
If you're from India: the treaty doesn't help your OPT wages. Focus on correct NRA withholding, FICA exemption, and using Sprintax to file accurately.
If you're from Nepal (or any non-treaty country): no treaty benefit available. Make sure your W-4 withholding is correctly calculated for NRAs, confirm your FICA exemption is in place, and file 1040-NR on time. The FICA exemption alone saves you ~7.65% of your gross wages, that's real money even without a treaty.
The China treaty exemption is the most underutilized tax benefit in the international student community: I've seen students miss it for multiple years and leave thousands of dollars on the table. If you're from China, this is the one tax tip worth verifying before every filing season.
FAQ
Q: Do F-1 students from India get any tax treaty benefits in the US? A: The US-India tax treaty (1989) exists, but Article 21 primarily covers payments received from Indian sources for education and maintenance, not wages earned from a US employer on OPT or CPT. Most Indian F-1 students receive no treaty benefit on their US wages.
Q: How much do F-1 students from China save with the tax treaty exemption? A: The US-China tax treaty Article 20 exempts up to $5,000 of student income from federal tax each year. At typical NRA tax rates of 12–22%, this translates to roughly $600–$1,100 in annual federal tax savings.
Q: Does Nepal have a tax treaty with the US for F-1 students? A: No. The US does not have a tax treaty with Nepal. Nepali F-1 students pay full federal income tax at standard NRA rates with no treaty-based exemption on any type of income.
Q: How do I claim a tax treaty benefit on my Form 1040-NR? A: Report your full income on Line 1a of Form 1040-NR, then enter the treaty exemption on Schedule OI, Item L, listing your country, treaty article number, and the amount excluded. Alternatively, submit Form 8233 to your employer before the tax year begins so they withhold on only the non-exempt portion.
Q: Can I still claim a tax treaty benefit if I've been in the US for more than 5 years? A: Generally no. Once you become a resident alien (after 5+ calendar years and meeting the Substantial Presence Test), the saving clause in most US tax treaties prevents you from claiming student-specific treaty benefits. Confirm with a tax professional for your specific treaty and situation.
