The short answer
General information, not legal or tax advice. TNPath provides general educational information and document-automation tools. It is not a law firm or an accounting firm, and it does not provide tax advice, legal advice, eligibility opinions, or case-specific strategy. Worker classification and TN status both turn on individual facts; where classification is in question, consider an independent review by a U.S. immigration lawyer.
Two different systems use the word “employment,” and they do not ask the same question. For TN purposes, USCIS states that a TN applicant works in “a prearranged full-time or part-time job for a U.S. employer or entity” and that “self-employment does not qualify” under the TN classification. For U.S. federal tax purposes, the IRS separately determines whether a worker is an employee or an independent contractor by examining the degree of control and independence in the relationship, under common-law rules grouped into behavioural control, financial control, and the relationship of the parties. The form that reports the pay follows the classification: employers report wages paid to an employee on Form W-2, and payers report nonemployee compensation on Form 1099-NEC. A label in a contract, or the form a payer prefers to issue, does not by itself decide either system’s answer.
This page covers worker classification only. Residency, the Substantial Presence Test, FICA, RRSPs, TFSAs, FBAR/FATCA and Canada’s departure tax are covered in the TN visa taxes guide.
The TN side: a prearranged job, and no self-employment in substance
The TN regulation defines “engage in business activities at a professional level” as “the performance of prearranged business activities for a United States entity, including an individual,” and states that it “does not authorize the establishment of a business or practice in the United States in which the professional will be, in substance, self-employed” (8 CFR 214.6(b)). The same definition states that a professional is deemed to be self-employed if the professional renders services to a corporation or entity of which the professional is the sole or controlling shareholder or owner (8 CFR 214.6(b)).
USCIS guidance restates the same structure. The USCIS TN page lists, as one condition, that the applicant “will work in a prearranged full-time or part-time job for a U.S. employer or entity.” The USCIS Policy Manual adds that a formal arrangement may be “through an employee-employer relationship or through a signed contract between the alien or the alien’s employer and a person or enterprise in the United States” (USCIS Policy Manual, Volume 2, Part P, Chapter 2). The Policy Manual also lists factors relevant to whether an applicant is self-employed, including whether the U.S. enterprise is a separate legal entity from the applicant, whether the applicant has substantial control over the enterprise, and whether evidence indicates the enterprise was established to facilitate the applicant’s self-employment.
Two points follow from those texts, stated neutrally. The TN texts focus on a prearranged arrangement with a U.S. employer or entity, and on whether the professional is, in substance, self-employed — including through an entity the professional solely or controllingly owns. And the TN texts do not use the IRS forms as their test: nothing in 8 CFR 214.6(b) or in the Policy Manual chapter cited above states that receiving a Form 1099-NEC, standing alone, answers the TN question, and nothing in them states that receiving a Form W-2, standing alone, answers it either. Whether any particular contract-based arrangement is self-employment “in substance” is a fact-specific determination; the sources state factors, not a bright-line rule, and assign no fixed weight to the tax form issued.
The tax side: the IRS common-law classification test
For federal employment tax purposes, the IRS states that a business must determine whether the individuals providing services are employees or independent contractors before it can determine how to treat payments for those services. The IRS describes the test as an examination of “all information that provides evidence of the degree of control and independence” in the relationship. IRS Topic No. 762 groups the evidence into three categories:
- Behavioural control — facts showing whether the business has a right to direct and control what work is accomplished and how the work is done, through instructions, training, or other means.
- Financial control — facts showing whether the business has a right to direct and control the financial and business aspects of the worker’s job, including unreimbursed business expenses, the worker’s investment in facilities or tools, whether the worker makes services available to the relevant market, how the business pays the worker, and the extent to which the worker can realize a profit or incur a loss.
- Relationship of the parties — facts showing the type of relationship, including written contracts describing the relationship the parties intended to create, whether the business provides employee-type benefits such as insurance, a pension plan, vacation pay, or sick pay, the permanency of the relationship, and the extent to which the worker’s services are a key aspect of the regular business of the company.
The IRS states that there is no set number of factors that makes a worker an employee or an independent contractor, that no one factor stands alone, and that the entire relationship is considered. The IRS also states that either the business or the worker may file Form SS-8 to ask the IRS to review the facts and officially determine the worker’s status, and that a determination may take at least six months.
The Canada Revenue Agency publishes a parallel guide for Canadian working relationships, RC4110, Employee or Self-employed?, which states that employment status affects entitlements and treatment under the Canada Pension Plan, the Employment Insurance Act, and the Income Tax Act, and that the facts of the working relationship as a whole decide the status. The CRA guide addresses Canadian payer relationships; it is included here only because readers arriving from Canada sometimes conflate the two countries’ tests. The IRS test above is the one the IRS describes for U.S. federal employment tax purposes. This page addresses U.S. federal classification only; classification can also arise under state law and other federal statutes, which are not described here.

What the two forms report
The IRS FAQ on Form 1099-NEC describes the forms as serving different functions. Employers use Form W-2, Wage and Tax Statement, to report wages, tips, or other compensation paid to an employee, and to report the employee’s income, Social Security, and Medicare taxes withheld; employers furnish Form W-2 to the employee and to the Social Security Administration, which shares the information with the IRS. Payers use Form 1099-NEC, Nonemployee Compensation, to report payments made in the course of a business to a person who is not an employee for services, at or above the reporting threshold stated in the FAQ, and to report any amount of federal income tax withheld under the backup withholding rules.
The IRS FAQ states the Form 1099-NEC services threshold as $600, and $2,000 for payments made after December 31, 2025. Reporting thresholds are set by law and IRS guidance and can change, so confirm the current-year figure in the current-year IRS instructions before relying on it.
On withholding, the IRS states the general rule as follows: a business must generally withhold and deposit income taxes, Social Security taxes, and Medicare taxes from wages paid to an employee, and must also pay the matching employer portion of Social Security and Medicare taxes and unemployment tax on those wages; generally, a business does not have to withhold or pay taxes on payments to independent contractors.
On self-employment tax, the IRS describes it as a tax consisting of Social Security and Medicare taxes primarily for individuals who work for themselves, states a rate of 15.3% (12.4% for Social Security and 2.9% for Medicare) on net earnings from self-employment as described on its self-employment tax page, and states that self-employed individuals generally figure the tax on Schedule SE and may have to pay it through estimated taxes. That page states its rate and wage-limit figures by tax year; figures for a given year belong in the current-year IRS instructions.
Where the two systems meet for TN visa holders
The IRS page on Social Security and Medicare liability for foreign professionals addresses TN status directly. It states that professionals who arrive in the United States in TN status “are fully liable for U.S. Social Security/Medicare taxes from the very first day of U.S. employment if they are employed on the payroll of the university or other employer,” regardless of whether they are resident or nonresident aliens for tax purposes, unless a totalization agreement relieves them. The same page states that a nonresident alien is not liable for self-employment tax, that a resident alien is liable for self-employment tax under the same conditions as a U.S. citizen, and that, as a general rule, U.S. immigration law does not permit nonimmigrants to earn self-employment income. That page also notes that if a nonimmigrant earns self-employment income, the income is subject to U.S. federal income tax and, if the person becomes a resident alien, to self-employment tax.
Read together, the sources describe three separate questions that are sometimes collapsed into one:
- Immigration: Is the arrangement a prearranged job for a U.S. employer or entity, and is the professional in substance self-employed within the meaning of 8 CFR 214.6(b) and the USCIS Policy Manual factors?
- Tax classification: Under the IRS common-law categories, is the worker an employee or an independent contractor for federal employment tax purposes?
- Tax reporting and payment: Which form reports the pay, what is withheld, and — for a person taxed as self-employed — how is self-employment tax calculated and paid?
The sources reviewed do not state that the answer to any one of these questions automatically supplies the answer to another, and they do not describe how, if at all, an adjudicator in one system treats a determination made in the other system. This page makes no claim about cross-system effect; where both systems are in question at once, consider an independent review by a U.S. immigration lawyer.
Misclassification, as the IRS describes it
The IRS states that if a business classifies an employee as an independent contractor with no reasonable basis for doing so, the business may be held liable for employment taxes for that worker. The same page describes relief provisions that can apply where a reasonable basis existed and required information returns were filed consistently, and a Voluntary Classification Settlement Program under which eligible taxpayers may reclassify workers as employees for future tax periods with partial relief. The page also states that workers who believe they have been improperly classified as independent contractors can use Form 8919 to figure and report the employee’s share of uncollected Social Security and Medicare taxes due on their compensation.
This section reports the IRS description only. Whether any provision applies to a particular business or worker is a determination the sources reserve to the IRS process described above, including Form SS-8.
Common questions
Does a TN visa require a W-2, or can a TN visa holder be paid on a 1099?
The TN sources reviewed do not frame the requirement in terms of tax forms. The regulation requires prearranged business activities for a U.S. entity and does not authorize a business or practice in which the professional will be, in substance, self-employed (8 CFR 214.6(b)). The IRS separately classifies a worker as an employee or an independent contractor under its common-law categories, and the reporting form follows that classification. Because both questions are fact-specific, consider an independent review by a U.S. immigration lawyer where an arrangement is borderline.
What test does the IRS use to tell an employee from an independent contractor?
The IRS examines all evidence of the degree of control and independence, grouped as behavioural control, financial control, and the relationship of the parties (IRS Topic No. 762). The IRS states that no single factor and no set number of factors decides the outcome, and that the entire relationship is considered.
Do Social Security and Medicare taxes apply from the first day of TN employment?
The IRS states that professionals in TN status who are employed on an employer’s payroll are fully liable for U.S. Social Security and Medicare taxes from the very first day of U.S. employment, whether resident or nonresident aliens for tax purposes, unless a totalization agreement relieves them. The existing TN visa taxes guide covers the U.S.–Canada totalization agreement and the certificate of coverage in more detail.
What happens if a worker is classified as a contractor but the relationship looks like employment?
The IRS states that a business that classifies an employee as an independent contractor with no reasonable basis may be held liable for employment taxes for that worker, and describes relief provisions and a voluntary reclassification program. Either the business or the worker may file Form SS-8 to ask the IRS to determine the worker’s status. How those provisions apply to any specific relationship is fact-specific.
Is the Canadian employee-versus-self-employed test the same as the U.S. test?
The CRA guide RC4110 describes a Canadian analysis in which the facts of the working relationship as a whole decide employment status, for purposes that include the Canada Pension Plan, employment insurance, and the Canadian Income Tax Act. The IRS describes its own common-law categories for U.S. federal employment tax purposes. The sources present the two tests separately and for different statutory purposes; this page does not equate them.
