Hiring in the United States
One person working for a foreign-owned business inside the United States can change that business's filing position, and the change is not the same depending on whether the paperwork calls that person a contractor or an employee. Getting the label right comes before anything else, because the two categories trigger different obligations and different tests for whether the business itself has a U.S. presence.
Classification is not a choice made on a form
Calling someone an independent contractor on a services agreement does not make them one for tax purposes. Worker classification under U.S. tax law turns on the degree of control the business exercises over how the work is done, not on what the contract is titled or which form the worker receives at year end.
Treas. Reg. §31.3121(d)-1(c)(2) states the common law test in its usual form: a worker is an employee if the business for whom services are performed has the right to control and direct the worker, not only as to the result to be accomplished, but as to the details and means by which that result is achieved. A worker who is subject only to the result, and who is free to determine the method and means of accomplishing it, is generally an independent contractor. The IRS's own guidance, developed from Rev. Rul. 87-41, groups the relevant facts into three broad categories that examiners still use as a working framework: behavioral control, meaning instructions and training given to the worker; financial control, meaning how the worker is paid, whether business expenses are reimbursed, and whether the worker has a real opportunity for profit or loss; and the type of relationship, meaning written contracts, benefits, permanency, and whether the services are a key aspect of the regular business.
No single factor is decisive, and the analysis is holistic. A worker set fixed hours, given a company email address and equipment, required to use specified software, supervised on a daily basis, and paid a fixed periodic amount regardless of output looks like an employee whatever the contract says. A worker engaged for a defined project, who sets their own hours, uses their own equipment, bills by invoice, and works for other clients at the same time looks like a contractor. Most real arrangements sit somewhere between those two descriptions, which is exactly why the classification question gets litigated as often as it does.
What follows from getting it wrong
A business that treats a worker as a contractor when the facts describe an employee has generally failed to withhold and deposit federal income tax withholding, has not paid its share of Federal Insurance Contributions Act tax under IRC §3111, and has not paid federal unemployment tax under IRC §3301. IRC §3403 makes the employer liable for the income tax it should have withheld, without regard to whether the worker separately paid tax on the same income, and IRC §3509 provides a reduced-rate calculation available in certain circumstances where the failure was not intentional, but the reduced rates still apply on top of penalties and interest that accrue from the original due date.
A separate and personal exposure sits behind the corporate one. IRC §6672 imposes the trust fund recovery penalty on any person responsible for collecting, accounting for, and paying over withheld employment taxes who willfully fails to do so. That penalty reaches individuals, including officers, and it is not limited by the entity's own assets. A foreign owner who signs off on how U.S. workers are paid should understand that a misclassification finding does not stay inside the corporate entity.
Relief exists for a business that had a reasonable basis for treating workers as contractors, under the safe harbor originally enacted as section 530 of the Revenue Act of 1978 and still administered on those terms. It requires consistent treatment of similarly situated workers, consistent filing of information returns such as Form 1099-NEC for those workers, and a reasonable basis for the position, which can rest on judicial precedent, a past IRS audit that did not challenge the treatment, or a recognized industry practice. It is a defense to raise when the classification is challenged, not a substitute for getting the classification right at the outset.
Withholding and registration obligations for a genuine employee
Where the worker is genuinely an employee, the employer has to obtain a federal employer identification number if it does not already have one, and register for state withholding and unemployment insurance in the state where the employee actually performs services, which is generally the controlling state regardless of where the employer itself is organized or headquartered.
A U.S. citizen or resident employee completes Form W-4 to set federal withholding. A nonresident alien employee completes Form 8233 to claim any applicable treaty exemption for compensation, or otherwise is subject to the modified withholding procedure for nonresident aliens described in IRS Publication 15-T, which adds a fixed amount to wages before computing withholding to approximate the absence of the standard deduction nonresident aliens generally cannot claim. Employment tax deposits and Form 941 quarterly filings follow from there, along with an annual Form W-2 and, where applicable, state equivalents.
This is the point at which the firm's own scope has to be stated plainly. Ali Gulzari, CPA, EA advises on the tax exposure that hiring in the United States creates and on the classification and structuring questions that determine which obligations apply. The firm does not run payroll. A business that determines it has a genuine U.S. employee needs a payroll provider to handle withholding calculations, deposits, and the recurring filings that follow, and that provider should be engaged before the first paycheck is issued, not after the first quarter has already passed without a Form 941 on file.
The separate question a worker's authority can raise
Classification for employment tax purposes is one analysis. Whether a worker's activity creates a U.S. tax presence for the foreign business itself is a different one, and it applies to genuine independent contractors as much as to employees.
Under Treas. Reg. §1.864-7(d), the U.S. activities of an agent can be attributed to a foreign principal, making the principal engaged in a U.S. trade or business, where the agent is not independent and acting in the ordinary course of its own business, and either regularly exercises the authority to negotiate and conclude contracts in the name of the principal, or regularly fills orders on the principal's behalf from a stock of the principal's goods that the agent maintains. A worker who genuinely just executes instructions, without authority to bind the business or commit it to terms, sits outside that description even where the underlying employment classification question is close. A worker, whether formally an employee or a contractor, who can sign off on customer contracts, set pricing, or commit the business to supplier terms without further approval is a different fact pattern, and it is this contract-concluding authority, not the worker's job title, that the dependent agent analysis actually looks for.
The two questions can point in different directions on the same set of facts. A worker correctly classified as an independent contractor for employment tax purposes, because they control their own hours and methods, can still be a dependent agent for trade-or-business purposes, because independence for common law control purposes and independence in the narrower sense the agency regulation requires, meaning acting in the ordinary course of the agent's own separate business rather than as a captive representative of one principal, are not the same test answered the same way.
The worker's own filing question, when the worker is also a nonresident
A business hiring in the United States does not necessarily hire a U.S. citizen or a green card holder. It is common for the person doing the work, whether classified as an employee or an engaged as a contractor, to be a nonresident alien present in the United States temporarily. That person has a filing question of their own, separate from the employer's exposure, and the two are worth distinguishing because a foreign owner is sometimes the one filling both roles at once.
IRC §864(b)(1) treats the performance of personal services within the United States as a per se trade or business within the United States, without regard to whether the individual holds an office here or maintains any continuing presence. A narrow exception applies where the nonresident is present in the United States for 90 days or less during the taxable year, total compensation for the services does not exceed $3,000, and the services are performed for a foreign person not engaged in a U.S. trade or business, or for a foreign office of a domestic employer. Outside that narrow combination of facts, a nonresident who performs services physically inside the United States is engaged in a U.S. trade or business by that fact alone, and generally has to file Form 1040-NR for the year, obtain an individual taxpayer identification number if one is not already on file, and report the compensation as effectively connected income.
The payor's withholding obligation tracks a different provision. Compensation paid to a nonresident alien for personal services performed in the United States is generally subject to withholding under IRC §1441, but where the recipient furnishes Form 8233 claiming a treaty exemption, or where the compensation is treated as wages subject to graduated withholding because the recipient is a common law employee, the flat 30% rate under §1441(a) does not apply in the same way it would to a passive FDAP payment. A genuine independent contractor without a treaty exemption on file is generally subject to withholding at the statutory rate on the gross payment, which the payor reports on Form 1042-S rather than Form 1099-NEC, since Form 1099-NEC is a reporting form for U.S. persons. This is a separate mechanism from the backup withholding and employment tax questions already described, and a business that assumes every contractor gets a Form 1099-NEC and every employee gets a W-2 will misroute the paperwork the moment either one is a nonresident alien.
| Fact pattern | Employment tax question | Trade-or-business question |
|---|---|---|
| Worker sets own hours, uses own equipment, works for multiple clients | Likely an independent contractor under the common law control test | Not attributed to the principal unless it also has authority to conclude contracts on the business's behalf |
| Worker follows detailed instructions, uses company systems, works fixed hours for one payer | Likely an employee regardless of the contract label | Employee's U.S. activity is generally attributed to the employer directly |
| Worker is a genuinely independent sales representative who can sign customer contracts | May remain a contractor for employment tax purposes | Can still create a U.S. trade or business for the principal under the dependent agent rule |
Documentation that supports either answer
Because both analyses are fact-intensive, the underlying documentation matters more than the label chosen at the outset. A written agreement describing the scope of authority, whether the worker can bind the business, how instructions are given and how much day-to-day supervision actually occurs, how the worker is paid, and whether the worker performs similar services for others, is the record either analysis is eventually built from. That documentation should reflect how the relationship actually operates, not only how it was described when the relationship began, since a role that started as a narrowly scoped project engagement can drift into something closer to ongoing supervised work without anyone updating the paperwork that describes it.
What to do before hiring anyone in the United States
Decide the classification question deliberately, based on the actual working arrangement rather than on which label is administratively simpler. If the answer is employee, line up a payroll provider before the engagement begins, because there is no grace period for the first missed deposit. If the answer is contractor, confirm that the scope of the role, particularly any authority to negotiate or conclude agreements on the business's behalf, is documented accurately, because that authority is what the dependent agent analysis will examine if the question of a U.S. trade or business ever comes up. Neither exercise predicts a result for a particular business. Both depend on facts specific to the working relationship, and those facts should be written down while the arrangement is being set up rather than reconstructed later from memory.
