Article 20(c) of a U.S. tax treaty is the subsection that exempts a limited amount of U.S. wage income from federal income tax for students, apprentices, and business trainees visiting from the treaty partner country. In the U.S.-China treaty — the version people usually have in mind when they use the phrase — the cap is $5,000 per year. The dollar amount, the time limit, and even whether an employment income exemption exists at all depend on which country’s treaty applies to you.
Where 20(c) Sits Within Article 20
Most U.S. tax treaties use Article 20 to address students and trainees, and the U.S.-China treaty is the cleanest illustration of the three-part structure. It exempts qualifying visitors from U.S. tax on:
- Payments received from abroad for maintenance, education, study, research, or training (subsection a).
- Grants or awards from a government, scientific, educational, or other tax-exempt organization (subsection b).
- Income from personal services performed in the United States, up to $5,000 per taxable year (subsection c).1Internal Revenue Service. United States-People’s Republic of China Income Tax Convention
Other treaties cover the same ground but organize it differently. The U.S.-Germany treaty spreads the same provisions across numbered paragraphs 2 through 5 and caps employment income at $5,000 across a four-year window.2Internal Revenue Service. Tax Convention With the Federal Republic of Germany The U.S.-UK treaty has no subsections and no employment income exemption at all; it only covers payments arising outside the United States for maintenance, education, or training.3U.S. Department of the Treasury. U.S.-U.K. Income Tax Treaty The lettered “(c)” label only maps cleanly onto the China-style layout, so always read your own treaty.
Who Qualifies
Every version of Article 20 shares the same eligibility test. You must have been a resident of the treaty partner country immediately before arriving in the United States, and your presence here must be solely or principally for education, training, or gaining technical experience.1Internal Revenue Service. United States-People’s Republic of China Income Tax Convention If you came to the U.S. primarily for long-term employment or immigration, the exemption doesn’t apply regardless of visa category.
A “student” generally attends a recognized educational institution. A “business apprentice” acquires trade or technical skills; the U.S.-Germany treaty names the German equivalents, Volontäre and Praktikanten, expressly.2Internal Revenue Service. Tax Convention With the Federal Republic of Germany A “business trainee” typically covers individuals gaining specialized knowledge from a U.S. firm or institution.
Intent to return home matters. Filing for a green card, or letting home-country ties like a dwelling or driver’s license lapse, cuts against you. Students on F, J, M, or Q visas who have been in the U.S. for more than five calendar years face additional scrutiny: the IRS requires them to show they don’t intend to reside permanently in the United States and have complied with their visa requirements.4Internal Revenue Service.

How Much U.S. Wage Income Is Exempt
The annual cap on exempt employment income varies substantially by country. The IRS publishes Tax Treaty Table 2 as the master reference. A sampling:5Internal Revenue Service. Tax Treaty Table 2 – Compensation for Personal Services of Students and Trainees
- $2,000 per year: Cyprus, Indonesia, South Korea, Morocco.
- $3,000 per year: Egypt, Israel.
- $5,000 per year: China, Czech Republic, France, Germany.
- $7,500 per year: Jamaica.
- $8,000 per year: Bangladesh, Estonia, Latvia, Lithuania.
- $9,000 per year: Belgium, Bulgaria, Iceland, Malta, and Germany when the income is for gaining experience.
- $10,000 for various countries under U.S. Government-sponsored programs.
Some countries have different caps depending on whether the income comes from study-related work, gaining professional experience, or a government exchange program. Germany, for instance, allows $5,000 per year for student employment and a separate $10,000 for gaining experience.5Internal Revenue Service. Tax Treaty Table 2 – Compensation for Personal Services of Students and Trainees Anything above the cap is fully subject to U.S. federal income tax.
How Long the Exemption Lasts
Time limit language varies more than most people expect. The U.S.-China treaty says the benefit extends “only for such period of time as is reasonably necessary to complete the education or training” — no fixed number of years.1Internal Revenue Service. United States-People’s Republic of China Income Tax Convention The U.S.-India treaty uses almost identical phrasing.6Internal Revenue Service. Tax Convention With the Republic of India The U.S.-Germany treaty sets a four-year limit on the employment income exemption, and the U.S.-UK treaty limits its business apprentice provision to one year.3U.S. Department of the Treasury. U.S.-U.K. Income Tax Treaty
The treaty clock runs alongside a separate five-calendar-year window the IRS uses to decide whether F, J, M, or Q visa holders are still nonresident aliens under the substantial presence test.4Internal Revenue Service. Exempt Individual – Who Is a Student They are different clocks. Once either expires, the corresponding benefit ends — although a few treaties (see China, below) keep the Article 20 exemption alive even after you become a resident alien.
How to Claim the Benefit
Form 8833 With Your Return
Every year you rely on a treaty to reduce your U.S. tax, attach Form 8833, Treaty-Based Return Position Disclosure, to your federal return. It identifies the treaty country, the article you’re invoking, and the Internal Revenue Code provision being overridden.7Internal Revenue Service. About Form 8833 – Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b) File it even if the treaty reduces your taxable income to zero. Skipping it triggers a $1,000 penalty under 26 U.S.C. § 6712, or $10,000 for a C corporation.8Office of the Law Revision Counsel. 26 USC 6712 – Failure to Disclose Treaty-Based Return Positions
Form 1040-NR
Nonresident aliens report U.S. income and claim treaty positions on Form 1040-NR with Form 8833 attached. Deadlines split by income type: if you received wages subject to U.S. income tax withholding, the return is due April 15. If not, it’s due June 15.9Internal Revenue Service. Instructions for Form 1040-NR
Form W-8BEN to Stop Withholding Up Front
Waiting until you file means the exempt tax comes back as a refund months later. To keep the U.S. payer from withholding on exempt amounts in the first place, give them a completed Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting, with a statement identifying the specific treaty article.10Internal Revenue Service. Form W-8BEN – Certificate of Foreign Status of Beneficial Owner The payer can then reduce or eliminate withholding on the exempt portion.
Form 8843 to Preserve Nonresident Status
Students on F, J, M, or Q visas file Form 8843, Statement for Exempt Individuals, each year to keep their U.S. days from counting toward the substantial presence test’s 183-day threshold. Attach it to your return, or send it separately by the return due date if you have no filing requirement.11Internal Revenue Service. Form 8843 – Statement for Exempt Individuals Miss it and the IRS can count all your days, which may reclassify you as a resident alien and complicate (though not always eliminate) your treaty position.
Variations That Change the Answer
China: Benefits Continue After Residency Change
Most treaty benefits disappear the moment you become a U.S. resident alien. The U.S.-China treaty is an exception. Article 20 continues to apply to Chinese students even after they pass the substantial presence test and become resident aliens for tax purposes.12Internal Revenue Service. Claiming Treaty Exemption for a Scholarship or Fellowship Grant That matters most to doctoral students and others whose programs stretch past year five.
India: Access to the Standard Deduction
Nonresident aliens normally cannot claim the U.S. standard deduction. Under Article 21(2) of the U.S.-India treaty, a resident of India temporarily in the U.S. for education or training is entitled to the same deductions as a U.S. citizen, including the standard deduction.6Internal Revenue Service. Tax Convention With the Republic of India For 2026, the single-filer standard deduction is $16,100.13Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
United Kingdom: No Wage Exemption
The U.S.-UK treaty protects foreign-source remittances for maintenance, education, and training but does not exempt any wages earned from a U.S. employer. Its only time-limited provision covers business apprentices, capped at one year.3U.S. Department of the Treasury. U.S.-U.K. Income Tax Treaty UK students working on campus should not expect an Article 20 benefit on those wages.
State Tax Is a Separate Question
Tax treaties are agreements between the U.S. federal government and foreign nations. They override federal income tax obligations but generally do not bind state governments. Some states voluntarily follow federal treaty positions; others ignore them entirely and tax nonresident alien income under their own rules. If you live in a state with an income tax, check that state’s treatment of treaty-exempt income separately. A treaty that zeroes out your federal bill may do nothing for your state liability.
