What are Differences Between 1099 and W2 Employees?
A W-2 employee works under your direction and control, has taxes withheld from every paycheck, and is covered by wage, overtime, and benefit laws. A 1099 contractor runs their own business, controls how the work gets done, pays their own self-employment tax, and is covered by none of those protections. The difference isn't what you call the arrangement or what the contract says. It's who controls the work.
Get it wrong and the bill comes from several directions at once: back taxes, back overtime, workers' comp premiums, and penalties from agencies that don't coordinate but do talk. Here's how to tell the difference, what the IRS actually looks at, and why Maine can reach a different answer than the IRS does.
Key Takeaways from this Article
- Classification is decided by the facts of the working relationship, not by a contract, a job title, or the worker's preference.
- The IRS weighs three categories of evidence: behavioral control, financial control, and the nature of the relationship.
- Maine applies additional requirements for workers' compensation and unemployment, so a worker can be a contractor to the IRS and an employee to the state.
- In Maine, workers are presumed to be employees, and the burden of proving otherwise sits with the business.
- Misclassification exposure includes back payroll taxes, unpaid overtime, workers' comp premiums, and penalties from multiple agencies.
What is a W-2 Employee?
A W-2 employee works for your business under your direction. You decide what work gets done and have the right to direct how, when, and where it happens. You withhold federal and state income tax, Social Security, and Medicare from their pay, match the FICA portion, and pay unemployment tax on their wages. At year end they get a Form W-2.
W-2 employees are covered by employment law in a way contractors aren't. Minimum wage applies. Overtime applies unless they're properly exempt. In Maine they're covered by workers' compensation from the first employee, earned paid leave above ten employees, and paid family and medical leave regardless of size. They count toward headcount thresholds for benefits and compliance obligations.
Employees can be full-time, part-time, seasonal, or temporary. None of that changes the classification. A student working eight hours a week in July is a W-2 employee.
What is a 1099 Contractor?
A 1099 contractor is a separate business you hire to deliver a result. They control how the work gets done, usually supply their own tools, often work for several clients, and can realize a profit or a loss on the engagement.
You don't withhold anything. They handle their own income tax and self-employment tax, which covers both halves of Social Security and Medicare, typically paying quarterly. Your only year-end obligation is issuing Form 1099-NEC by January 31 if you paid them $600 or more.
A note on the term: "1099 employee" is a contradiction, and it causes real confusion. A 1099 worker is not an employee at all. They're a vendor who happens to be a person. The phrase is common enough that everyone uses it, but the mental model it creates is exactly the one that leads to misclassification.
W-2 Employee vs 1099 Contractor
| W-2 employee | 1099 contractor | |
|---|---|---|
| Who controls the work | The employer | The worker |
| Tax withholding | Employer withholds | None; worker pays their own |
| Payroll taxes | Employer pays half of FICA | Worker pays self-employment tax |
| Minimum wage and overtime | Yes | No |
| Workers' compensation | Covered | Not covered by you |
| Unemployment benefits | Eligible | Not eligible |
| Benefits | Usually offered | Their own responsibility |
| Tools and equipment | Usually employer's | Usually the worker's |
| Year-end form | W-2 | 1099-NEC, if paid $600 or more |
How Do You Determine Worker Classification?
Not by preference and not by paperwork. A signed independent contractor agreement is evidence, but it doesn't settle anything. If the facts show an employment relationship, the contract loses.
The IRS looks at three categories of evidence, weighing the whole picture rather than scoring points.
Behavioral Control
Does the business have the right to direct how the work is done? Note "the right to," not whether you actually exercise it. A business that could tell the worker how to do the job has behavioral control even if it never bothers.
Signs pointing toward employee: you set the hours, you say where the work happens, you provide instructions on methods and sequence, you train them in your way of doing things, you supervise or evaluate the details rather than just the result.
Financial Control
Does the worker have a real stake in the business side of the arrangement?
Signs pointing toward contractor: they've made a significant investment in their own equipment, they have unreimbursed business expenses, they're free to offer their services to other clients, they're paid a flat fee for a project rather than by the hour, and they can actually lose money if the job runs long.
That last one carries weight. A genuine contractor who underbids a job absorbs the loss. An employee gets paid either way.
Type of Relationship
What does the overall arrangement look like?
Signs pointing toward employee: the relationship is open-ended rather than project-based, you provide benefits like insurance or paid leave, and the work they do is a core part of what your business does rather than something peripheral.
That last point is the one small businesses miss. If you run a landscaping company and hire someone to landscape, that work is your core business and it's hard to argue they're an outside vendor. Hiring someone to redesign your website is a different matter.
When You Genuinely Can't Tell
File Form SS-8 and ask the IRS to determine status. It's free, either the business or the worker can file, and the answer is binding on the IRS.
The catch is timing. A determination can take months, and filing can prompt the IRS to look at how you've classified comparable workers. It's a reasonable move for a genuinely ambiguous arrangement you intend to keep, and a poor one if you suspect the answer you'll get.
What Happens if You Misclassify a Worker?
The exposure is wider than most employers expect, because several agencies have an interest and they reach their own conclusions.
Federal tax. Back income tax withholding, both halves of FICA, and federal unemployment tax on everything you paid that worker, plus interest and penalties. Relief provisions can reduce the amount where the misclassification was genuinely unintentional and you filed the required 1099s. Where the IRS finds it was deliberate, that relief disappears.
Wage and hour. If the worker should have been a non-exempt employee, you owe unpaid overtime for every week they worked more than forty hours, often with liquidated damages doubling it. Maine's minimum wage is well above the federal floor, which widens the gap on anyone paid near the bottom.
Workers' compensation. Unpaid premiums, and far worse if the worker was injured while uninsured.
State unemployment. Back contributions and penalties, and a higher experience rate afterward.
Benefits. A worker reclassified as an employee may have a claim to benefits they were excluded from, including retirement plan participation.
These stack, and misclassification is rarely a one-person problem. If one worker in a role was misclassified, everyone in that role usually was.
Which Should You Hire?
Only once you've established which one the work actually is. The classification follows the nature of the work, not your preference, so this question really means: should this role be structured as employment or as a contracted engagement?
A contractor fits when the work is a defined project with an end, requires expertise you don't need year-round, can be judged on the result rather than the method, and the person genuinely runs their own business.
An employee fits when the work is ongoing, you need to direct how it's done, it's central to what your business does, and you want the continuity that comes from someone invested in the organization.
Cost comparisons are the common trap. Contractors look cheaper because the employer tax, benefits, and insurance aren't visible. But a contractor's rate usually builds those costs in, and the gap narrows once you count the time spent managing a vendor relationship rather than a team member.
FAQs: W-2 Employees and 1099 Contractors
-
A W-2 employee works under your direction with taxes withheld from their pay and is covered by minimum wage, overtime, workers' compensation, and unemployment. A 1099 contractor runs their own business, controls how the work is done, pays their own self-employment tax, and has none of those protections through you. The deciding factor is control over the work, not the contract or the job title.
-
Strictly speaking, no such thing exists. A worker who receives a 1099 is an independent contractor, meaning a separate business, not an employee. The phrase is common shorthand but it describes a contradiction, and the confusion it creates is one reason misclassification is so widespread.
-
Apply the IRS factors: who controls how the work is done, who bears the financial risk, and what the overall relationship looks like. A worker you schedule, train, supervise, and equip is an employee regardless of what the agreement says. If it's genuinely unclear, Form SS-8 lets you ask the IRS for a determination, though it can take months.
-
No. A signed agreement is one piece of evidence and it does not override the facts. Agencies look at how the relationship actually works. If you direct the schedule, supply the tools, and oversee the method, the worker is an employee no matter what either of you signed.
-
Yes. Maine applies its own definitions for workers' compensation and unemployment that are separate from the IRS test, and the Maine Department of Labor states that an employer may owe state unemployment tax or workers' compensation on a worker the IRS would treat as a contractor. Maine also presumes every worker is an employee, placing the burden of proof on the business.
-
Back federal income tax withholding, both halves of FICA, and unemployment tax with interest and penalties. Add unpaid overtime with potential liquidated damages, unpaid workers' compensation premiums, state unemployment back contributions, and possible benefit claims. The liability usually extends to everyone in the same role rather than the single worker who raised it.
-
Only if you paid them $600 or more during the year, in which case the deadline is January 31. Payments made through a third-party network or payment card are generally reported by the processor instead, so check how you paid before issuing one.
Getting a Classification Right Before It Matters
Classification decisions get made quickly, usually when someone needs help and a contractor seems simpler than running payroll for one more person. They get reviewed slowly, usually when that person files for unemployment or gets hurt.
The useful time to look at a relationship is while you're setting it up. Our HR consulting team works through classification with Maine employers against the actual facts of the arrangement, including the state tests that the IRS answer doesn't cover. If the answer is employee, onboarding them properly is straightforward and our pricing is published.
