1099 vs. W-2: the worker, the work, and what the facts say

Some workers are employees. Their pay is reported on a Form W-2. Some workers run their own business. Their pay is reported on a Form 1099. Which one fits is not picked from a menu. It follows how the work actually runs.

The label is not a choice

The form follows the facts. The facts do not follow the form.

A worker is not a contractor just because the business calls them one. A worker is not a contractor just because a paper they signed says so.

The IRS general rule, in plain words:

A person is an independent contractor if the business has the right to control or direct only the result of the work — not what will be done, and not how it will be done.

A person is generally an employee when the business has the right to direct and control the work itself — what the worker does, and how they do it.

That right counts even if the business never uses it. What matters is that the right is there.

Plain-words picture Hired to deliver a finished result, your own way, on your own schedule? That leans toward contractor. Told your exact hours, where to be, and each step of the job? That leans toward employee.

Why the answer matters

The two answers carry very different tax duties. This is what the IRS says each side means.

If the worker is an employee (W-2)

The business must withhold income taxes from the worker's wages.
The business must pay Social Security and Medicare taxes on wages paid to the employee.
The business must pay unemployment tax on those wages.

If the worker is an independent contractor (1099)

Businesses normally do not have to withhold or pay any taxes on payments to independent contractors.
The contractor's earnings are subject to self-employment tax. The contractor handles their own taxes.

That is why getting the facts right matters — for the business and for the worker.

How the IRS looks at it: three areas

The IRS does not look at one thing. It looks at the whole working relationship in three areas: how the work is controlled, how the money side is controlled, and what kind of relationship the two sides have.

1. Behavioral control — who directs how the work gets done?

This area asks: does the business have the right to direct and control how the worker does the work?

Instructions

More detailed instructions about when, where, and how to work may show the worker is an employee. Less detailed instruction shows less control.

How the work is judged

If the business measures the details of how the work is done, that points toward employee. If it measures just the end result, that can point either way.

Training

Training a worker on how to do the job is strong evidence the worker is an employee. So is ongoing training about procedures and methods. Independent contractors ordinarily use their own methods.

Plain-words picture Being trained step-by-step, and checked on each step, looks like employment. Being handed the finished result that is wanted — and left to choose the method — looks like contracting.

2. Financial control — who directs the money side of the job?

This area asks: does the business have the right to direct and control the business and financial side of the worker's job? The IRS looks at facts like these:

Significant investment. Has the worker put significant money into the equipment they use for the work?
Unreimbursed expenses. Independent contractors are more likely to have expenses nobody pays back.
Profit or loss. Can the worker make a profit on the job — or take a loss on it?
Open to other customers. Does the worker offer their services to other customers, out in the relevant market?
Method of payment. An employee is generally guaranteed a regular wage for an hourly, weekly, or other period of time. Independent contractors are most often paid a flat fee for the job.

Plain-words picture A steady weekly wage, with the business supplying the tools, looks like employment. A flat fee for the whole job, your own equipment, your own expenses, and other customers of your own — that looks like contracting.

3. Type of relationship — how do the two sides see the arrangement?

This area asks how the worker and the business understand their own arrangement. The IRS looks at facts like these:

Written contracts. A contract that describes what the parties intend is evidence of that intent. But the label in the contract, by itself, does not decide the answer.
Employee-type benefits. Benefits such as insurance, a pension plan, or vacation pay point toward employee — benefits like those are generally not given to independent contractors.
How long it lasts. A relationship expected to continue indefinitely points toward employee. Work for a specific project, or a specific period of time, points toward contractor.
A key part of the business. The IRS also looks at whether the services the worker performs are a key aspect of the business.

Plain-words picture Hired with benefits, with no end date, to do the very work the business exists to do? That looks like employment. Brought in for one named project, for a set stretch of time, with no employee benefits? That looks like contracting.

Side by side, in plain words

Every line below comes from the IRS facts on this page. Read it as a picture of leanings — not as a score. No line on its own settles anything.

What the facts can point toward
Points toward employee (W-2)	Points toward independent contractor (1099)
Behavioral control
Detailed instructions about when, where, and how to work Judged on the details of how the work is done Trained by the business on how to do the job, or given ongoing training on procedures and methods	Only the result is directed — not what will be done or how Less detailed instruction; the worker uses their own methods
Financial control
Guaranteed a regular wage for an hourly, weekly, or other period of time	Significant investment in the equipment used for the work Unreimbursed expenses the worker carries A real chance of profit — or loss — on the job Services offered to other customers in the market Paid a flat fee for the job
Type of relationship
Employee-type benefits: insurance, a pension plan, vacation pay The relationship is expected to continue indefinitely The worker's services are a key aspect of the business	The work is for a specific project or a specific period of time No employee-type benefits

Leans neither way: judging only the end result can point either way — on its own, it leans neither toward employee nor toward contractor.

One more fact belongs with this table: a written contract is evidence of what the parties intend — but the label in it does not decide the answer by itself.

No single fact decides

There is no one question that settles this. There is no checklist score.

Classification depends on the facts in each situation. The IRS weighs all the evidence — the degree of control, and the degree of independence — across the whole relationship.

Real work is often mixed. Some facts lean one way. Some lean the other. That is normal, and it is why the whole picture is what counts.

Still not sure? Form SS-8

Sometimes, after looking at everything, it is still genuinely unclear. The IRS has a form for exactly that.

Form SS-8, Determination of Worker Status. A business or a worker may file it and ask the IRS to determine the worker's status — whether the services are performed as an employee or as an independent contractor.

You do not have to guess. You can ask the IRS itself.

One last note: other laws, other tests

The IRS test above is for federal taxes. Other agencies — such as the U.S. Department of Labor, for wage-and-hour law — and the states use their own tests. So the same worker can be classified one way for taxes and another way under a different law.
