Before year-end tax forms go out, review every person you paid as an independent contractor and ask whether they were really in business for themselves. The IRS looks at three groups of evidence, behavioral control, financial control and the type of relationship, and the Department of Labor applies its own “economic reality” analysis under federal wage law. If the answers point toward an employee, fix the classification going forward rather than issuing another contractor form and hoping. This guide sets out a practical review you can complete in an afternoon, and what to do with a borderline case.
Why the Review Belongs at Year-End
December and January are when classification decisions become visible. Contractor payments are totalled for information returns, payroll is reconciled and budgets for next year are set. It is also when a business can most cleanly change how a worker is engaged, starting with the first pay period of the new year, instead of switching mid-project.
There is a second reason. Many small businesses add contractors during the autumn rush: extra hands for fulfilment, event staff, a bookkeeper to catch up before the holidays. Arrangements made quickly are the ones most likely to drift into something that looks like employment.
Two Tests, Two Agencies
Federal classification is not governed by a single test. The two that matter most for a typical employer are:
- The IRS common-law test, which decides employment tax treatment: income tax withholding, Social Security and Medicare, and federal unemployment tax.
- The Fair Labor Standards Act analysis, applied by the Department of Labor’s Wage and Hour Division, which decides minimum wage and overtime rights.
States can and do apply their own, sometimes stricter, tests for unemployment insurance, workers’ compensation and state wage law. A worker can pass one test and fail another, so treat a “contractor” label as a conclusion you have to support, not a starting point.
The IRS approach
The IRS says it is critical that business owners correctly determine whether the people providing services are employees or independent contractors, and that all the evidence of control and independence has to be weighed, with no single factor deciding the question. The evidence falls into three categories:
- Behavioral: does the company control, or have the right to control, what the worker does and how they do the job?
- Financial: are the business aspects of the work controlled by the payer, such as how the worker is paid, whether expenses are reimbursed and who provides tools and supplies?
- Type of relationship: is there a written contract, are employee-type benefits provided, is the relationship expected to continue, and is the work a key part of the business?
The Department of Labor approach
The Department of Labor’s most recent final regulation on employee or independent contractor status under the FLSA was published on January 10, 2024 and took effect on March 11, 2024, according to the Wage and Hour Division’s misclassification page. On February 26, 2026 the Department proposed a new rule to replace it, with comments due by April 28, 2026. Because federal rulemaking can change during the year, check that page for the current status before relying on any summary, including this one. Whichever version applies, the analysis asks the same underlying question: as a matter of economic reality, is the worker in business for themselves, or economically dependent on you?
The Year-End Classification Checklist
Run each contractor through these questions. Write the answers down; a short memo per worker is useful evidence that you considered the issue in good faith.
| Question | Points toward contractor | Points toward employee |
|---|---|---|
| Who sets the hours? | Worker chooses when and how much to work | You set shifts or require set hours |
| Who decides how the work is done? | You agree on results; worker chooses methods | You train, supervise and direct methods |
| Who supplies tools, equipment and space? | Worker invests in their own | You provide everything |
| Can the worker make or lose money? | Sets prices, takes other clients, bears costs | Paid by the hour with no real business risk |
| Does the worker serve other clients? | Yes, and markets services publicly | Works only for you, often full-time |
| How long is the relationship? | Defined project with an end | Open-ended, renewed indefinitely |
| Is the work core to your business? | Specialist work outside your main operation | The same work your employees do |
No single row decides the outcome. A web developer who builds your site, sets their own schedule and has a dozen other clients looks very different from a “contractor” who stocks your shelves on a rota you write.

Common Patterns That Need a Second Look
- Former employees rehired as contractors to do the same job. If nothing changed except the paperwork, the classification probably did not change either.
- Seasonal “contractors” working scheduled shifts. Holiday help who clock in, wear your uniform and follow a supervisor’s instructions are typically employees.
- Long-running part-timers. A bookkeeper who has worked set hours for you for three years, with no other clients, raises the permanence and dependence questions.
- Workers you train in your methods. Training is a strong sign of control.
What to Do With a Borderline or Wrong Classification
Change the arrangement going forward
If the review shows someone is effectively an employee, the cleanest step is to bring them onto payroll from a clear start date, ideally the first payroll of the new year. That means a Form W-4, a Form I-9, state new-hire reporting, and inclusion in workers’ compensation and unemployment insurance. Our explainer on W-2 employment versus contractor arrangements sets out how the two differ for the worker, which helps when you explain the change to them.
Consider a staffing or employer-of-record arrangement
If you want flexibility without carrying payroll administration, a staffing agency or employer of record can employ the worker and bill you. That does not make classification problems disappear, but it moves the payroll obligations to a party set up for them. See our comparison of employer of record and staffing agency models.
Ask the IRS for a determination
Either a business or a worker can file Form SS-8 to ask the IRS for an official determination of status. The IRS says the process takes at least six months, so it is not a quick fix for this year’s forms.
Look at the Voluntary Classification Settlement Program
The IRS runs an optional Voluntary Classification Settlement Program that lets eligible businesses reclassify workers as employees for future tax periods with partial relief from federal employment taxes. Applications use Form 8952, and there are eligibility conditions. A tax professional can tell you whether it fits your situation.
If the Classification Holds Up
For workers who genuinely are independent contractors, year-end is about paperwork. Confirm you have a current Form W-9 for each one, check the information-return threshold for the year, and diarise the filing deadline. Our separate guide to Form 1099-NEC for 2026 payments covers the new reporting threshold and the early-2027 deadline.

Frequently Asked Questions
Does a signed contractor agreement make someone an independent contractor?
No. A written contract is one piece of evidence under the IRS “type of relationship” category, but the actual working relationship is what counts. A contract that says “independent contractor” will not outweigh day-to-day control over how and when the work is done.
Is the IRS test the same as the Department of Labor test?
No. The IRS uses a common-law test for employment taxes, and the Department of Labor applies an economic reality analysis under the Fair Labor Standards Act. States may use different tests again. Check each one that applies to you.
Can I switch a contractor to an employee in the middle of the year?
Yes. You can bring a worker onto payroll at any time. Many businesses prefer the start of a new year because it keeps the year’s tax reporting simpler, but a known misclassification should not wait just for a tidy date.
What happens if I get classification wrong?
A misclassified employee may be owed the employment tax treatment, minimum wage and overtime that an employee receives, and state agencies may look at unemployment insurance and workers’ compensation coverage. The IRS Voluntary Classification Settlement Program exists to give eligible businesses partial relief when they correct the problem going forward.
Do part-time workers have to be contractors?
No. Hours worked do not determine classification. A part-time worker you direct and schedule is a part-time employee.
