W-9 Contractor or Employee? The Difference Could Cost Your Business Thousands

“I’ll just pay them as a 1099.”

I hear small-business owners say this all the time, especially contractors and tradespeople who need an extra set of hands.

It sounds simple. Have the worker fill out a W-9, pay them without withholding taxes and send them a 1099 at the end of the year.

But here is the problem:

A W-9 does not automatically make someone an independent contractor.

You cannot turn an employee into a contractor by calling them one, paying them by check or having them sign an independent contractor agreement.

What matters is how the working relationship actually operates.

If someone should have been treated as an employee, the business could become responsible for payroll taxes, penalties, unpaid overtime, workers’ compensation issues and other employment-related costs.

What Is a W-9?

A Form W-9 provides a payee’s:

• Legal name

• Business name

• Address

• Federal tax classification

• Taxpayer identification number

Small businesses commonly collect W-9s from independent contractors and vendors. The information helps determine whether a Form 1099 must be issued after the end of the year.

The W-9 is paperwork.

It does not determine whether the person is legally an independent contractor.

Sending someone a 1099 does not prove that they were classified correctly either.

Do Corporations Receive a 1099?

Generally, payments made to a C corporation or S corporation are not reported on Form 1099-NEC.

But do not assume every business with “LLC” in its name is exempt.

An LLC may be taxed as:

• A sole proprietorship

• A partnership

• An S corporation

• A C corporation

The vendor’s completed W-9 tells you how the business is taxed.

There are exceptions. Payments for legal services generally remain reportable even when the attorney or law firm is incorporated. Certain medical and healthcare payments to corporations may also be reportable on Form 1099-MISC.

How you paid matters too.

Payments made by credit card or through certain third-party payment processors are generally handled under Form 1099-K reporting rules. The business should not report the same payment again on Form 1099-NEC.

This is why I tell clients to collect the W-9 before making the first payment.

Do not wait until January to start chasing people.

For payments made during 2026, the federal reporting threshold for Form 1099-NEC is generally $2,000. Different thresholds applied in previous years, and future amounts may change, so reporting requirements should be confirmed each year.

What Is an Independent Contractor?

A true independent contractor generally operates a separate business.

They may:

• Work for multiple customers

• Advertise their services

• Set their own schedule

• Decide how to complete the work

• Invest in their own tools and equipment

• Negotiate their own rates

• Submit invoices

• Accept or reject projects

• Have an opportunity for profit or loss

For example, suppose a plumbing company hires an independent bookkeeper.

The bookkeeper has her own business, works for several clients, uses her own computer and software, controls her schedule, decides how to perform the work and sends the plumbing company an invoice.

That looks much more like a legitimate business-to-business relationship.

Now compare that with someone who reports to the shop every morning, follows the company’s schedule, drives the company truck, primarily uses company tools, performs the same work the company sells and works almost exclusively for that company.

That arrangement needs a much closer look.

Calling the worker a subcontractor does not settle it.

What Is an Employee?

An employee generally performs work under the direction or control of the business.

The business may decide:

• When and where the employee works

• Which jobs the employee performs

• How the work must be completed

• What tools, equipment or vehicle will be used

• How the employee is trained and supervised

Employees are normally paid through payroll. The employer withholds applicable payroll taxes and may also be responsible for:

• Employer payroll taxes

• Workers’ compensation insurance

• Unemployment insurance

• Paid sick leave

• Minimum wage and overtime

• Meal and rest break requirements

• Other employment-related obligations

Paying someone through payroll costs more than handing them a check.

I understand why small businesses are tempted to avoid it.

But avoiding payroll does not eliminate the responsibility. It may only postpone the bill until an audit, injury, unemployment claim or wage complaint brings the problem to light.

What Does the IRS Look At?

For federal tax purposes, the IRS looks at the entire relationship between the worker and the business.

The main areas include:

Behavioral Control

Does the business control, or have the right to control, what the worker does and how the work is completed?

This can include instructions, training, scheduling, supervision and how the worker’s performance is evaluated.

Financial Control

Who controls the financial side of the work?

Consider who provides tools and supplies, whether expenses are reimbursed, how the worker is paid and whether the worker can make a profit or suffer a loss.

The Relationship

Is there a written contract?

Are benefits provided?

Is the relationship expected to continue indefinitely?

Is the worker performing an important part of the company’s regular business?

No single factor automatically decides the answer.

You can read more in the IRS worker-classification guidance.

California Has a Tougher Test

California generally starts with the assumption that a worker is an employee.

Under California’s ABC test, the hiring business must generally establish all three of the following:

A: The Worker Is Free From Control

The worker must be free from the hiring business’s control and direction, both in the written agreement and in the way the work is actually performed.

B: The Work Is Outside the Business’s Usual Work

The worker must generally perform work outside the usual course of the hiring business.

A plumbing company hiring an independent bookkeeper is one example. Bookkeeping is not the service the plumbing company sells to its customers.

A plumbing company hiring someone to perform plumbing work requires a closer review.

C: The Worker Operates an Independent Business

The worker must be customarily engaged in an independently established business performing that type of work.

A business card, LLC, contractor’s license, insurance policy or signed agreement may help support this.

None of them automatically determines the worker’s status.

What About Construction Subcontractors?

California has specific rules that may apply to construction subcontractors.

Depending on the situation, the requirements can involve:

• A valid contractor’s license

• Freedom from the hiring contractor’s control

• A separate business location

• A written subcontract

• Authority to hire and fire workers

• Financial responsibility for mistakes or incomplete work

• The ability to work for other businesses

• Required business licenses and registrations

A licensed subcontractor performing the same trade as the hiring contractor is not automatically an employee.

But a license and W-9 do not automatically make the person an independent contractor either.

The complete arrangement matters, and a different legal classification test may apply when an exception to the ABC test is met.

California construction businesses should have questionable arrangements reviewed by a qualified CPA or employment attorney.

You can find additional information through the California Labor and Workforce Development Agency.

“But They Asked to Be Paid as a 1099”

That does not decide the classification.

A worker may prefer contractor pay because they do not want taxes withheld. A business owner may prefer it because payroll costs more.

The two of you cannot simply agree to ignore worker-classification laws.

The actual relationship still matters even if the worker:

• Asks to be paid as a contractor

• Signs an independent contractor agreement

• Works part time

• Has another job

• Gives you a W-9

• Receives a 1099

• Is paid in cash

And please do not call someone a “1099 employee.”

For most small-business situations, someone is either an employee who receives a W-2 or an independent contractor who may receive a 1099-NEC.

Those are different classifications with different responsibilities.

Red Flags to Watch For

A worker may lean toward employee status if:

• You control their regular schedule

• You tell them exactly how to perform the work

• You provide most of the tools and equipment

• They work mainly or exclusively for you

• They perform the same service your business sells

• You pay them like a regular employee instead of paying invoices

• They consistently represent themselves as part of your company

• They cannot hire or send someone else to complete the work

• The relationship continues indefinitely

A worker may lean toward independent contractor status if:

• They operate an established business

• They advertise to other customers

• They work for multiple clients

• They control their schedule

• They decide how to complete the work

• They invest in their tools and equipment

• They submit invoices

• They carry appropriate licenses and insurance

• They negotiate their prices

• They can accept or reject projects

• They have a real opportunity for profit or loss

These are only indicators.

Contractors can bill hourly. A business might provide equipment for practical or safety reasons. A new contractor may temporarily have only one customer.

The complete working relationship matters.

This is not a checklist where one answer decides everything.

What Can Happen If You Get It Wrong?

Misclassifying an employee as an independent contractor can result in:

• Back payroll taxes

• Interest and penalties

• Unpaid minimum wages or overtime

• Meal and rest break claims

• Unemployment insurance assessments

• Workers’ compensation problems

• Paid sick leave claims

• Legal expenses

• Additional federal or state penalties

The situation can become especially serious if someone is injured on a job site and your insurance company or a government agency determines that the worker should have been covered as an employee.

Saving money on payroll today can become a very expensive cleanup later.

What Should You Collect From a Subcontractor?

Depending on your business and industry, a subcontractor file may need:

• Completed Form W-9

• Written subcontractor agreement

• Certificate of liability insurance

• Workers’ compensation certificate or applicable exemption information

• Current contractor or professional license

• Business name and contact information

• Scope of work

• Invoices

• Payment records

• Required industry-specific documents

Collecting these documents helps protect your business.

But paperwork cannot repair a working relationship that actually functions like employment.

Ask Before the First Payment

The best time to review someone’s classification is before they begin working.

Not when payroll reports are due.

Not when it is time to prepare 1099s.

And definitely not after someone files an unemployment claim or gets hurt.

Before hiring someone, ask:

• What work will this person perform?

• Is it part of what my business normally sells?

• Who controls the schedule and work methods?

• Who provides the tools and equipment?

• Does this person operate a real independent business?

• Are they properly licensed and insured?

• Does the written agreement match the actual arrangement?

• Should I have the situation reviewed professionally?

The Bottom Line

A W-9 is paperwork.

It is not proof that someone is legally an independent contractor.

If you control someone like an employee, schedule them like an employee and use them to perform the regular work of your business, stop and review the arrangement before paying them as a contractor.

Also, do not assume every LLC needs a 1099 or that every corporation is exempt.

Collect a completed W-9 before the first payment so you know who you are paying and how the business is taxed.

A little work at the beginning is much cheaper than cleaning up years of payroll, taxes, penalties and missing paperwork later.

Not Sure Your Subcontractor Paperwork Is Complete?

Ask me.

I can help you collect and organize W-9s, insurance certificates, licenses and other subcontractor documents. I can also help make sure payments are recorded correctly and flag situations that may need professional review.

Final worker-classification decisions may need to be confirmed with your payroll provider, CPA, insurance professional or employment attorney.

I would much rather help you get the paperwork organized now than try to track everything down in January. 😂
