Employee or contractor? Worker classification for payers, and what each answer means for your filings

Four categories, not two

Publication 15-A (2026) opens its discussion of workers with the point most payers skip: before you can decide how to treat a payment, you have to know the relationship. The person performing services may be an independent contractor, a common-law employee, a statutory employee or a statutory nonemployee. The IRS manual adds that the result is set by federal law, not chosen by the business (IRM 4.23.5.4).

Labels and contracts don't change the answer. Publication 15-A: “The substance of the relationship, not the label, governs the worker's status.” Full-time or part-time makes no difference, and supervisors and managers are employees like anyone else. A corporate officer is generally an employee; an officer who performs no or only minor services and receives no pay is not, and a director is not an employee for services as a director.

The common-law test, as the IRS states it

The core rule is control. A worker is generally your employee “if you have the right to control what will be done and how it will be done”, even if you give the employee freedom of action. The mirror image: “an individual is an independent contractor if you, the person for whom the services are performed, have the right to control or direct only the result of the work and not the means and methods of accomplishing the result.” The question is the right to control, not whether you exercise it.

Publication 15-A groups the evidence into three categories:

On behavioral control, the publication says “The key consideration is whether the business has retained the right to control the details of a worker's performance or has instead given up that right.” Highly specialized professionals may get no instructions at all and still be employees if the business has the right to control how results are achieved.

No single factor decides. The IRS's classification page: “There is no magic or set number of factors that makes the worker an employee or an independent contractor and no one factor stands alone in making this determination.” The same page tells businesses to look at the entire relationship and to document each factor used in reaching the decision. That record matters later: it is the start of the reasonable basis that section 530 asks for. The IRS manual adds that what counted as evidence of control can change over time; its example is a delivery driver's company uniform, which today may have more to do with customer safety than control (IRM 4.23.5.7.1).

Publication 15-A works through examples by industry. Two from construction show the line: a remodeling supervisor paid hourly, under almost constant supervision, with the owner paying suppliers and carrying the insurance, is an employee; a tile setter with his own tools, paid by the piece but working full time to the corporation's specifications with frequent inspections and no place of business of his own, is also an employee.

Statutory employees and statutory nonemployees

Some workers are classified by statute whatever the common-law answer.

Statutory employees are workers who are contractors under the common-law rules but fall into one of four groups in Publication 15-A: certain agent or commission drivers (beverages other than milk, meat, vegetables, fruit, bakery products, laundry or dry cleaning); full-time life insurance sales agents working primarily for one company; home workers using your materials and specifications; and full-time traveling or city salespersons taking orders from wholesalers, retailers, contractors or hotels and restaurants. Social security and Medicare apply when all three conditions are met: the contract states or implies substantially all services are performed personally, the worker has no substantial investment in equipment other than transportation, and the services are continuing for the same payer. Then:

• “Don't withhold federal income tax from the wages of statutory employees.”
• Furnish a Form W-2 with box 13 (Statutory employee) checked; report pay in box 1 as other compensation and social security and Medicare wages and tax in boxes 3 to 6.
• FUTA applies to drivers and salespersons, not to life insurance agents or home workers.

The categories cannot overlap with common-law status. IRM 4.23.5.7.4: “By definition, a worker cannot be a statutory employee under IRC 3121(d)(3) if that worker is a common law employee.”

Statutory nonemployees are direct sellers, licensed real estate agents and certain companion sitters. Direct sellers and real estate agents are self-employed for all federal tax purposes when substantially all their pay is tied to sales or output rather than hours, and they work under a written contract saying they will not be treated as employees. A companion sitting placement service is not the sitters' employer if it neither pays nor receives their wages and is paid a fee.

What follows from each answer

Publication 15-A summarizes the employee side: an employer must generally withhold income tax, withhold and pay social security and Medicare tax, and pay unemployment tax on wages; it doesn't generally have to withhold or pay any federal taxes on payments to independent contractors. But the contractor side has its own duties. Publication 15 says “You must generally withhold 24% of certain taxable payments if the payee fails to furnish you with their correct TIN”, and nonemployee compensation is one of those payments; the W-9 is how you get the TIN. For payments made after 2025, Publication 15 notes that P.L. 119-21 raised the Form 1099-NEC reporting threshold for payments for services from $600 to $2,000 in a calendar year, with the backup withholding threshold for those payments raised to match. Deposit timing on the employee side, and the penalties for missing it, are in Form 941 deposits and the failure-to-deposit penalty.

What a wrong answer costs

Publication 15 is direct: “You'll generally be liable for social security and Medicare taxes and withheld income tax if you don't deduct and withhold these taxes because you treated an employee as a nonemployee.” IRC 3509 softens the employee-side amounts, at rates that depend on whether you filed the required Forms 1099:

Three conditions come with the reduced rates. “You can't recover the employee share of social security tax, Medicare tax, or income tax withholding from the employee if the tax is paid under section 3509.” You still owe the full employer share. And the rates are unavailable if you withheld income tax but not social security and Medicare, for reclassifying statutory employees, or, under IRC 3509(c), “if such liability is due to the employer's intentional disregard of the requirement to deduct and withhold such tax.” FUTA, penalties and interest come on top, and the missed 1099s carry their own information return penalties. Publication 15-A adds that if you classify an employee as a contractor with no reasonable basis, the section 530 relief described next won't apply.

Fixing it: section 530, VCSP and CSP

Section 530 relief. Publication 15-A states the conditions: a reasonable basis for not treating the worker as an employee, all required information returns filed consistent with that treatment, and no worker in a substantially similar position treated as an employee for any period after 1977. It does not cover technical service specialists (engineers, designers, drafters, programmers, systems analysts and similar) placed with a client by a firm, though it can cover one you contract with directly. Late 1099s are the most common way payers lose it; see section 530 and late 1099s.

Voluntary Classification Settlement Program (VCSP). For a payer that wants to move workers to employee treatment before the IRS raises it. Per the IRS VCSP page, you agree to treat the class as employees going forward and in exchange “Pay 10 percent of the employment tax liability that would have been due on compensation paid to the workers for the most recent tax year, determined under the reduced rates of section 3509(a)”, with no interest or penalties on that amount and no employment tax audit of those workers' classification for prior years. The Form 8952 instructions (Rev. November 2025) set eligibility: you are treating the workers as nonemployees now and have done so consistently; you filed all required Forms 1099 for them for the three preceding calendar years; you are not under employment tax examination (nor is any member of your affiliated group); you are not under DOL or state examination on their classification; and you complied with any prior IRS or DOL classification audit. Timing: “Form 8952 should be filed at least 120 days before the date you want to begin treating the class or classes of workers as employees.” The taxpayer, not a representative, must sign it.

Classification Settlement Program (CSP). The examination counterpart, offered by IRS examiners when the payer timely filed its 1099s: a settlement of 100 or 25 percent of one year's tax at 3509 rates. How the IRS runs that exam is in employment tax examinations as the IRS runs them, and the two programs are compared in CSP and VCSP.

Asking the IRS: Form SS-8

Publication 15-A: “If you want the IRS to determine whether or not a worker is an employee, file Form SS-8 with the IRS.” Workers file it too, and the information is shared: the form warns that what you provide may be disclosed to the firm, worker or payer named, and “If you do not want this information disclosed to other parties, do not file Form SS-8.” It must be fully completed, with copies of the Forms W-2, 1099-MISC or 1099-NEC for each year contested. A determination against a business can lead further: the IRS manual lists SS-8 Unit referrals, made when the unit finds workers were improperly treated as non-employees, among the sources of employment tax examinations (IRM 4.23.23.3.1.1.8). What to do when a worker files one is in a Form SS-8 filed against your company, and the patterns in published determinations can be searched in the SS-8 determinations explorer.
