Form 8233: Stopping US Withholding on Wages and Fees Exempt Under the Treaty

A Canadian who performs services in the US, as an employee for a short assignment or as an independent contractor for a US client, may be exempt from US tax on the compensation under the treaty. The US payer must still withhold unless the exemption is documented. For dividends, interest, and royalties, the document is the Form W-8BEN. For compensation for personal services, it is Form 8233, which the payee completes and the payer submits to the IRS. Without it, the payer withholds (graduated rates on wages, 30% on independent fees), and the Canadian recovers the tax only by filing a 1040-NR the following year.

Key takeaways

• Form 8233 claims a treaty exemption from withholding on compensation for personal services performed in the US by a non-resident alien individual: employee wages exempt under Article XV, independent contractor fees exempt under Article VII (business profits, absent a US fixed base), and certain student, teacher, and researcher income.
• The payee completes it; the payer files it with the IRS within five days of receipt and can stop withholding ten days later unless the IRS objects. It covers one payer and one year.
• Employee wages: exempt under Article XV if under $10,000 for the year, or if the employee is present 183 days or fewer in any twelve-month period and paid by a non-US employer without a US permanent establishment. A Canadian employed by a US company does not qualify under the second branch (the employer is US-resident) and qualifies only under the $10,000 rule.
• Independent fees: exempt under Article VII if the contractor has no fixed base or permanent establishment in the US. Entities use Form W-8BEN-E instead.
• A US TIN is required on Form 8233: an SSN or an ITIN. Applicants without one file Form W-7 first or concurrently.

Form 8233 versus W-8BEN

The W-8BEN certifies foreign status and treaty entitlement for passive income (dividends, interest, royalties) and is given to the payer, who keeps it on file. Form 8233 certifies treaty exemption for compensation for personal services and must be sent by the payer to the IRS, which has ten days to object. A Canadian consultant who receives fees from a US client provides Form 8233 (as an individual) or W-8BEN-E (as a corporation); a Canadian who receives dividends provides W-8BEN. Both are needed if both kinds of income are involved.

Employees

A Canadian employee sent to the US by a Canadian employer for a project meets the Article XV exemption if the assignment stays under 183 days in any twelve-month period and the Canadian employer bears the cost (no US PE charged for the work). The employee completes Form 8233 with the treaty article, the expected amount of exempt compensation, and the dates; the employer submits it and stops US withholding. If the assignment runs past 183 days, the exemption fails retroactively for the whole period and the employer must withhold on all of it.

A Canadian employed directly by a US company for US work is not exempt under the 183-day branch (the employer is US-resident) and is exempt only if total US compensation for the year is under $10,000, which rarely applies to real employment. Most Canadians working for US employers in the US are simply taxable in the US on the wages.

Independent contractors

A Canadian consultant, speaker, performer, or professional who performs services in the US for a US client is exempt from US tax on the fees under Article VII if they have no fixed base in the US (an office, a regular workplace). Form 8233 documents the exemption for an individual; the US client then does not withhold 30% and does not issue a Form 1099 (it may issue a Form 1042-S showing exempt income). A Canadian corporation providing the services files W-8BEN-E with the limitation-on-benefits section completed.

Entertainers and athletes are an exception: Article XVI allows the US to tax them if gross receipts exceed $15,000 in the year, regardless of a fixed base, and Form 8233 does not apply above that threshold.

Students, teachers, and researchers

The treaty's provisions for students (Article XX) exempt certain payments from abroad; Form 8233 with the applicable statement is used by Canadian students and trainees receiving US-source scholarship or compensation that the treaty exempts.

When it is not filed

The payer withholds: graduated rates on wages (as if the employee were a US resident), 30% on independent fees. The Canadian files a 1040-NR after the year, reports the income as exempt under the treaty with Form 8833, and claims the refund of the withholding. The cost is the delay and the paperwork, not the tax. The payer that fails to withhold without a valid Form 8233 is liable for the tax, which is why US payers insist on the form.

Worked example

A Calgary engineer employed by a Calgary firm is sent to a Houston client for 90 days, earning $60,000 USD attributable to the US workdays. Separately, she gives a paid keynote at a Dallas conference for $8,000 as an independent speaker.

• Employment. Under 183 days; Canadian employer; no US PE charged. Exempt under Article XV. Form 8233 completed with the dates and the $60,000; the Canadian employer (registered with the IRS for the purpose) submits it; no US withholding. Wages taxed in Canada.
• Speaking fee. No US fixed base; exempt under Article VII. Form 8233 provided to the conference organizer with her ITIN; no 30% withholding; no 1099. Fee taxed in Canada.
• Without the forms. Withholding of roughly $12,000 on the wages and $2,400 on the fee; recovered on a 1040-NR with Form 8833 the following year.

Practitioner note

Form 8233 is the form the US payer will ask for and the Canadian will not have, because it requires an ITIN and the ITIN takes weeks. We start the ITIN application when the engagement is signed, not when the payer asks. For employees on assignments near the 183-day line, we count the rolling twelve-month window every month, because the exemption fails for the whole period on day 184.
