Should I hire someone as a contractor or as an employee through an EOR?

Only within a narrow band. Classification is a legal conclusion drawn from how the work is actually performed, and the paperwork does not control the outcome. The Treasury regulation on common law employees is blunt: where an employer and employee relationship exists, the parties' designation of it as anything else is immaterial [5], and the IRS adds that a contract naming someone an independent contractor is not sufficient to determine that worker's status [4]. The useful question is which arrangement the facts already support, and what you would have to change to reach the other.

The test belongs to the worker's country

The deciding analysis is the one applying where the person works, and those analyses differ. US federal employment tax uses the common law right to control test [1][5], federal wage and hour law uses a separate economic reality analysis [9], California and Massachusetts apply an ABC test that begins from a presumption of employment [10][11], and the UK assigns the determination duty to the client [12]. One person can be an employee under one body of law and not another, so a single global contractor template rarely survives more than one country.

Where the genuine decision sits

The part you control is the shape of the engagement. Someone available during your business hours, working under your direction, on the product you sell, indefinitely, on equipment you provide, is an employee, and the only remaining question is how you employ them. An employer of record answers it by becoming the legal employer in the worker's country and running local payroll for you. A defined deliverable from someone who serves other clients and sets their own methods can stay a contractor [3].

The IRS groups evidence of control and independence into behavioral control, financial control, and the type of relationship, and the instruction is to weigh the whole relationship rather than score any one of them [1].

Behavioral control asks who decides how the work gets done

Behavioral control covers instructions about when and where to work, what tools to use, who performs which task, and the order the work follows; more detailed instruction means more control [2]. Two markers surprise companies most often: an evaluation system that measures how the work is performed rather than the result, and training in your procedures [2].

Financial control asks who carries the business risk

Independent contractors often hold a significant investment in their own equipment, are more likely to have unreimbursed expenses, and have a genuine opportunity for profit or loss along with freedom to seek other business [3]. Method of payment matters too, since an employee is generally guaranteed a regular wage for a set period [3].

Type of relationship asks what the parties built to last

Insurance, pension plans, paid vacation, and sick days are rarely granted to independent contractors, so extending them is evidence the other way [4]. Hiring with the expectation that the relationship continues indefinitely rather than for a specific project is evidence of employment intent, and work that is a key aspect of the business makes the right to direct more likely [4].

Four other layers can reach the same engagement, and each can arrive at a different answer than the federal tax test.

US wage and hour law runs a separate analysis

The Fair Labor Standards Act uses its own economic reality test, and the applicable version is in flux. On February 27, 2026 the Department of Labor proposed rescinding the 2024 analysis codified at 29 CFR part 795 and replacing it with the analysis from its January 7, 2021 final rule, with modifications; comments closed on April 28, 2026 and the proposal was not final as of the review date shown here [9]. The Wage and Hour Division has said it will no longer apply the 2024 rule's analysis in FLSA investigations, while that rule remains in effect for private litigation, so a plaintiff and a federal investigator can currently apply different analyses to identical facts [9].

Some states presume employment and make you disprove it

California Labor Code section 2775 treats a person providing labor or services for remuneration as an employee unless the hiring entity demonstrates all three ABC conditions: freedom from control and direction, work outside the usual course of that entity's business, and an independently established trade of the same nature [10]. Massachusetts applies a similar three-prong test under General Laws chapter 149, section 148B, with civil and criminal remedies that can reach corporate officers and agents [11]. The B prong catches technology companies, since an engineer building your product is rarely working outside a software company's usual course of business.

The UK and the EU look at actual performance

Under the UK off-payroll working rules the client usually determines the worker's status and must produce a status determination statement with its reasons, though for a small client outside the public sector the worker's intermediary decides [12]. Directive (EU) 2024/2831 creates a rebuttable presumption of employment for platform work where facts indicating direction and control are found, with Member State transposition due by 2 December 2026 [13].

The employer pays the back taxes and contributions the worker was never enrolled in, plus penalties, and in some places the exposure reaches individual officers. The IRS baseline: classify an employee as an independent contractor with no reasonable basis and you may be held liable for employment taxes for that worker, though relief may be available where a reasonable basis exists [1].

The US federal tax arithmetic

Internal Revenue Code section 3509 sets the rates where an employer fails to withhold by reason of treating an employee as not being an employee: withholding is computed as if the amount required equaled 1.5 percent of wages, and the employee share of FICA as if the tax were 20 percent of the amount otherwise imposed [7]. Those figures double to 3 percent and 40 percent where the employer also missed the information reporting requirements without reasonable cause, and the section does not apply where the failure was due to intentional disregard, which returns the employer to full liability [7].

The worker can open the question without you

Both firms and workers file Form SS-8 to request a determination of the status of a worker for federal employment tax purposes [6]. A contractor refused unemployment benefits can start that alone, long after the work is over.

Company tax exposure travels with the arrangement

A long-running engagement abroad can also raise a question about your own taxable presence, since treaties generally define a permanent establishment as a fixed place of business through which an enterprise carries on its business, with business profits attributable to it taxable there [14].

Match the arrangement to the facts you can honestly describe, then revisit when those facts change. Genuine contractors exist in large numbers, and pushing every engagement onto an employer of record is expensive and often unnecessary.

When a contractor is genuinely appropriate

Use a contractor where the person runs an actual business: several clients, their own methods and equipment, unreimbursed expenses, and a real chance of profit or loss [3]. Short defined projects fit, as does independent specialist work such as a translation, a security audit, or a fixed-scope design system. The engagement should end with the deliverable, since an expectation that it continues indefinitely is evidence of employment intent [4].

When an employer of record is the right answer

Use one where the role is employment in substance and you have no registered entity in the worker's country. The provider becomes the local legal employer and administers payroll, withholding, and statutory entitlements, so you can direct the work normally without that direction creating a liability [2]. Opening your own entity makes more sense once headcount in one country outgrows per-employee fees, or when you need something an employer of record cannot easily give, such as local equity or a regulated license.

Triggers to convert a contractor to employment

• You start setting hours or requiring availability during your working day [2].
• The contractor stops taking other clients and depends on you for nearly all income [3].
• The contract has renewed for a year or more with no end date [4].
• You start reviewing how the work is done rather than the result [2].
• You ship equipment or reimburse expenses [3].
• The work becomes a key aspect of your business, or you want to grant benefits [4].

An employer of record solves the mechanics of employing someone in a country where you have no entity. Several adjacent problems stay with you.

It does not clean up the period before you switched

Moving someone onto an employment contract going forward does not address the months or years they were paid as a contractor, since section 3509 reaches the employer's liability for the period the person was treated as not an employee [7]. In the US the correction route is the Voluntary Classification Settlement Program, where eligible taxpayers reclassify prospectively and pay 10 percent of the employment tax liability that would have been due for the most recent tax year under the reduced section 3509(a) rates, with no interest or penalties [8]. It is closed to anyone already under an IRS employment tax audit or a state or federal classification audit [8].

It does not make the classification analysis go away

Some providers offer contractor payments and employment on one platform, which can suggest the classification question was outsourced with the invoicing. The tests still apply to your relationship with the worker, and the regulation is explicit that the parties' own description is immaterial where employment exists in substance [5].

It is not a substitute for legal advice

Outcomes depend on the facts of an engagement and the law of a jurisdiction, and the US federal wage and hour standard was mid-rulemaking on the date this page was verified [9]. A Form SS-8 request or an opinion from local counsel costs far less than a reclassification assessment [6].
