A 1099 contractor is independent and pays their own taxes. A W-2 employee is on your payroll with tax withholding and statutory benefits. An EOR is a third party that becomes the W-2 employer of your worker in a state or country where you have no entity. Same worker classification (W-2), different legal employer.
If you are hiring someone in the United States, three letters keep coming up: 1099, W-2, and EOR. The first two are IRS tax-form classifications. The third is a service model that lets you employ someone where you have no entity. They get pitched as alternatives, and that is part of the confusion. A 1099 contractor is independent. A W-2 employee is on your payroll. An EOR puts a worker on someone else’s W-2 payroll on your behalf, in a country or US state where you have no entity. Each one has a specific use case, and getting the call wrong has real tax, classification, and operational consequences.
This article walks through what each one is, when each is the right call, and how to combine them across a US-and-international footprint.
The One-Paragraph Version
A 1099 contractor is an independent worker. You issue them a Form 1099-NEC at year-end if you paid them $600 or more in trade or business. They handle their own income tax, their own self-employment tax (Social Security and Medicare combined, currently 15.3% on net earnings), and they have no statutory benefits from you. A W-2 employee is on your payroll. You withhold federal and state income tax, employee FICA, and any state-specific contributions. You pay employer FICA, FUTA, SUTA, workers’ compensation premiums, and (if applicable) state mandates such as paid family leave. You issue a Form W-2 at year-end. An EOR (Employer of Record) is a third party that becomes the W-2 employer of your worker. The worker gets a W-2 from the EOR, not from you. Useful when you have no entity in the worker’s state or country.
What 1099 Actually Means
A 1099 worker is an independent contractor under IRS classification. They invoice you for services, set their own hours within the bounds of the contract, supply their own tools, and bear their own business risk. The worker pays self-employment tax on net earnings, files Schedule C if they operate as a sole proprietor (or Form 1120-S if they elected S-corp status, or Form 1065 if they operate as a partnership), and they remit their own quarterly estimated tax payments. You file Form 1099-NEC for them at year-end if you paid them $600 or more.
The IRS uses three categories of evidence to classify a worker: behavioral control, financial control, and the type of relationship. The Department of Labor uses a different test (the economic-realities test). Several states (notably California with the ABC test under AB 5, Massachusetts, New Jersey) apply stricter standards. Even if your contract calls the worker an independent contractor, the legal test looks at the actual working relationship.
What W-2 Actually Means
A W-2 worker is your employee. You enter them into your payroll system, withhold income tax based on their Form W-4, deduct employee FICA (currently 7.65% combined for Social Security and Medicare), and remit those amounts to the IRS along with your matching employer FICA. You also pay FUTA at 0.6% on the first $7,000 of wages, SUTA at the rate set by the state for your unemployment account, workers’ compensation premiums (highly variable by industry and state), and any state-specific contributions (state disability, paid family leave, paid sick leave, and so on).
The W-2 employee receives statutory protections under the Fair Labor Standards Act, the Family and Medical Leave Act if you cross the headcount threshold, the Affordable Care Act if you cross 50 full-time equivalents, and the relevant state wage-and-hour laws. They are eligible for benefits you offer to your employee class, can be enrolled in your retirement plan, and you have ongoing reporting obligations (quarterly 941, annual W-2 distribution, state-by-state filings).
What An EOR Actually Does
An EOR is a service provider that becomes the W-2 employer of your worker on your behalf. The EOR carries the entity registration in the worker’s state (or country), runs payroll under its own EIN, files the employer tax forms, manages workers’ compensation, administers benefits, and handles termination. You direct the work. You pay the EOR a flat fee per employee per month (commonly $400 to $700 in the international context, similar in the US for state-coverage EORs), plus the worker’s gross salary and statutory employer contributions. An EOR is the fastest way to put a worker on a real W-2 in a state or country where you do not yet have an entity.
The EOR is not a way to dodge employment tax or classification rules. It is a way to skip the entity-registration project for a state or country where you have one or two employees and the cost of registering, paying state corporate tax, and running multi-state payroll outweighs the EOR fee.
Side-by-Side Comparison
The table below brings the three models into one view across the dimensions that finance and HR usually want to compare.
| Dimension | 1099 Contractor | W-2 Employee | EOR |
|---|---|---|---|
| Legal employer | No employer (worker is self-employed) | Your company | EOR’s entity |
| Year-end form | 1099-NEC | W-2 | W-2 from EOR |
| Tax withholding | None (worker pays own) | Federal, state, FICA | Federal, state, FICA (run by EOR) |
| Employer-side tax | None | FICA, FUTA, SUTA, state-specific | Same, paid by EOR; you fund |
| Statutory benefits | None | FMLA, ACA, state mandates if applicable | Same, administered by EOR |
| Pricing structure | Flat hourly or per-project rate | Salary plus benefits plus employer tax | $400 to $700 per month plus gross plus statutory |
| Misclassification risk | High if engagement looks like employment | None | None |
| Best for | Genuine independent specialists, project work | Full-time staff in a state where you operate | Full-time staff in a state or country where you do not |
The Classification Question
The IRS three-factor test (behavioral, financial, type of relationship) is the federal baseline. The DOL’s economic-realities test, used for FLSA wage-and-hour purposes, looks at six factors: opportunity for profit or loss, investments by the worker, permanence, nature and degree of control, integral nature of the work to your business, and the worker’s skill and initiative. Several states impose tougher tests. California’s ABC test under AB 5 presumes employment unless all three of: (A) the worker is free from your control, (B) the work is outside your usual course of business, and (C) the worker is customarily engaged in an independently established trade.
If a worker fails the test in the state or under the federal framework that applies, they are an employee regardless of how the contract describes them. Reclassification can result in back FICA, FUTA, SUTA, withholding tax, ACA penalties, and damages under state wage-and-hour law. It is one of the most expensive mistakes a small business can make.
Cost: How The Three Actually Compare
For a hypothetical engineer at a $100,000 annualized package:
As a 1099 at $50 per hour (2,000 hours), the worker bills $100,000. You pay $100,000 plus payment processing. There is no employer FICA, no benefits, no state unemployment. Net cost to you: roughly $100,000 to $101,000.
As a W-2 at $100,000 salary, employer FICA adds 7.65% ($7,650), FUTA tops out around $42, SUTA varies by state but figure 1% to 6% of the first $7,000-$36,000 of wages depending on state and your account experience (commonly $300 to $2,000), workers’ comp varies (around $200 to $1,000 for a desk job), benefits commonly run 15% to 25% of base, paid time off has a real cost. All-in cost typically lands at 25% to 35% above base. Roughly $125,000 to $135,000.
As an EOR W-2 at the same $100,000 salary, the EOR fee adds $400 to $700 per month ($4,800 to $8,400 annually), and the EOR runs all the same employer-side tax and benefits as you would. Total cost lands at roughly $130,000 to $145,000. The EOR premium over your own W-2 is the EOR fee plus a benefits markup, in exchange for not having to register and operate in that state or country yourself.
When 1099 Is The Right Call
1099 fits when the engagement is genuinely independent. Defined-scope projects (build this dashboard, audit this codebase, design this brand system). Specialist help where the worker has multiple clients and is not exclusive to you. Fractional roles split across a portfolio of customers. Short engagements with a clear deliverable. Workers who supply their own tools, set their own schedule, and bear business risk. The worker takes the tax-efficient self-employment path and you avoid statutory benefit obligations. Both sides know it is contract work.
When W-2 Is The Right Call
W-2 fits when the role is full-time, integrated into your team, and looks like employment. Engineers building your core product. Sales and customer success staff carrying quotas and reporting into managers. Operations and finance staff with daily team integration. Anyone whose work pattern, exclusivity, and duration would fail the IRS or DOL classification tests. If you would manage them like an employee, classify them like one.
When An EOR Is The Right Call
An EOR fits when you want a W-2 employee but you do not have an entity in their state or country. Common scenarios: hiring your first employee in a new US state and not wanting to register as a foreign-qualified entity, paying state corporate income tax, and running multi-state payroll for one person. Hiring an international employee in a country where you have no entity (the dominant EOR use case). Bridging while a state or country entity is being set up but the candidate needs to start sooner.
For US-only hires, EOR economics work best when state count is 1 to 3 in any single state where you have no nexus and no near-term plan to register. If you already operate in the state, an EOR is overkill.
The Hybrid Pattern Most US Companies Actually Run
Most US-headquartered companies end up with a mix. W-2 employees in their primary states (typically the founding state plus a small handful where headcount has grown enough to justify registration). 1099 contractors for genuine freelance and project work. EOR coverage for international hires and for one-off US-state hires where they do not want to incur the cost of state registration. The lines are clean: W-2 for full-time integrated staff, 1099 for genuinely independent project work, EOR for full-time staff in places where the entity does not operate.
Decision Framework
Walk through these questions for the specific hire you are planning:
- Does the work pattern look like employment? If yes (set hours, daily team integration, exclusive use, manager-employee dynamic, no business risk on the worker), it is W-2 or EOR. Do not run it as a 1099.
- Where will the worker live? A state where you have an entity: W-2. A state where you do not: EOR. A foreign country: EOR.
- Is the work genuinely defined-scope and short-term? 1099 is fine if the work pattern actually matches the test (independent control, multiple clients, business risk).
- Do you want the worker to have benefits and statutory protections? Yes leans W-2 or EOR. No is a signal to look at whether 1099 is even legitimate.
The Bottom Line
1099 is a contractor classification for genuinely independent work. W-2 is the employee path for full-time integrated staff in states where you operate. EOR is the W-2 path for staff in states or countries where you do not operate. The three are not interchangeable and the right call comes from the work pattern (employment-like vs independent) plus the geography (where you have an entity vs where you do not). Most US growing companies run all three across their footprint.
Frequently Asked Questions
A 1099 contractor is independent. They invoice you, set their own schedule, and pay their own income and self-employment tax. You issue a 1099-NEC at year-end if you paid them $600 or more. A W-2 employee is on your payroll. You withhold federal and state tax, deduct employee FICA, and pay employer FICA, FUTA, SUTA, workers' compensation, and state mandates. An EOR is a service that becomes the W-2 employer of your worker on your behalf, in a state or country where you have no entity. The worker gets a W-2 from the EOR, not from you.
Only when the work is genuinely independent. The IRS looks at behavioral control, financial control, and the type of relationship. The DOL applies a six-factor economic-realities test for wage-and-hour purposes. Several states (notably California's ABC test, Massachusetts, New Jersey) apply tougher standards. If the worker has set hours on your team, daily integration, exclusivity, no business risk, and a long-term relationship, they fail the test regardless of what the contract says. Defined-scope projects with multiple clients and worker-controlled methods are fine for 1099. Full-time integrated work is not.
Use an EOR when you do not have a legal entity in the worker's state or country. For US hires this typically means hiring in a state where you have no nexus and no plan to register in the next twelve to eighteen months. State registration carries cost (corporate income tax, payroll registration, multi-state filings, sometimes sales-tax exposure). For one or two employees, the EOR fee usually beats the registration overhead. For ten or more in a state, registering yourself is often cheaper. International hires almost always start with an EOR until headcount in the country justifies a local entity.
Yes. The worker is a regular W-2 employee for federal income-tax purposes. They have federal and state income tax withheld at source, FICA deducted, and they file Form 1040 at year-end. The only difference is the employer name on the W-2 (the EOR's entity, not yours). The worker counts toward Social Security earnings and quarters of coverage in the normal way. They are eligible for unemployment benefits under the EOR's state account. They can contribute to the EOR's 401(k) plan if it offers one. The W-2 itself is treated identically by the IRS and state tax authorities.
The IRS can assess back federal income tax withholding, employer FICA, and penalties under Section 3509 of the Internal Revenue Code. The DOL can assess back wages and overtime under the FLSA, plus liquidated damages. State tax authorities can pursue state income tax withholding, SUTA, and state-specific contributions. State labor agencies and class-action plaintiffs can pursue wage-and-hour, sick-leave, and benefits claims. California's Labor Commissioner has issued nine-figure misclassification awards against gig-economy companies. Audits typically look back three to four years, and reclassification of one worker often triggers review of others.
For a worker at $100,000 a year, a 1099 costs you about the gross billed (no employer FICA, no benefits, no state UI). A W-2 typically lands at 25% to 35% above base once employer FICA, FUTA, SUTA, workers' comp, benefits, and PTO are included. An EOR W-2 lands at roughly the same plus a $400 to $700 per month EOR fee. The 1099 looks cheapest on paper, but only when classification is honest. Misclassification fines and back-tax assessments quickly outpace the W-2 or EOR cost.
Technically yes if they perform genuinely separate kinds of work for you, but the IRS scrutinizes this pattern. A worker who is your employee for 30 hours per week and also bills you as a 1099 contractor for unrelated services has to be able to defend the contractor work as truly outside the employment scope. In practice, this rarely holds up. The cleaner solution is to either pay all the work as W-2 or to draw a hard line: either the worker is an independent specialist for everything you pay them, or they are an employee for everything.
For the EOR-employed worker, yes. They are a W-2 employee from day one, on the EOR's payroll, with all employer contributions handled. There is no contractor classification at issue. For workers you engage as 1099 contractors, an EOR does not help. The classification question is between you and the worker, governed by the IRS and DOL tests and the relevant state rules. An EOR is an alternative to running your own W-2 payroll, not an alternative to classifying correctly. The right answer to a misclassification problem is to convert to W-2, not to route the same arrangement through an EOR.
