The misclassification audit: how a 1099 clinician gets reclassified

Summary

A worker misclassification audit tests whether someone a practice pays on a 1099 is really an employee under the IRS common-law test — behavioral control, financial control, and the relationship. If the reviewer reclassifies them, the practice, not the worker, owes the back withholding, Social Security, Medicare, and unemployment tax, plus interest and penalties. The facts that decide it are how much control the practice exercises, not the label on the contract.

What a worker-misclassification audit examines

A worker-misclassification audit asks one question: does the practice control the person it pays on a 1099 enough that the law treats them as an employee? The IRS applies a common-law test that weighs behavioral control, financial control, and the relationship, and it looks past the contract to how the work actually happens 1Ref 1Internal Revenue Service (2026).Independent contractor (self-employed) or employee?.The IRS common-law test (behavioral control, financial control, relationship) that governs whether a paid worker is a contractor or employee, and that the misclassification exposure falls on the employer.. These reviews run as employment-tax examinations — by correspondence, in an office, or in the field — with a defined lookback period 2Ref 2Internal Revenue Service (2026).IRS audits.That the IRS conducts examinations by correspondence, office, or field, with a defined lookback period..

State labor agencies and the U.S. Department of Labor run their own parallel tests, so one set of facts can produce a federal tax reclassification and a separate state wage-and-hour or unemployment finding. This page covers the federal tax side; the employment-law consequences run on their own track.

The three buckets of control

The common-law test sorts the evidence into three buckets, and no single fact decides it — the reviewer weighs the whole picture 1Ref 1Internal Revenue Service (2026).Independent contractor (self-employed) or employee?.The IRS common-law test (behavioral control, financial control, relationship) that governs whether a paid worker is a contractor or employee, and that the misclassification exposure falls on the employer.. Behavioral control asks who directs how the work is done. Financial control asks who carries the business risk and owns the tools. The relationship factors ask how the two parties actually treat the arrangement over time, including whether it looks permanent.

Bucket	Points toward employee	Points toward contractor
Behavioral control	Set schedule, required methods, close supervision	Worker sets their own methods and hours
Financial control	Practice supplies tools, reimburses costs, pays hourly	Worker invoices, serves other clients, can lose money
Relationship	Indefinite term, benefits, restrictive covenants	Written project scope, no benefits, defined end

What reclassification costs, and who pays it

When a worker is reclassified, the practice — not the worker — owes what should have been withheld and paid all along 1Ref 1Internal Revenue Service (2026).Independent contractor (self-employed) or employee?.The IRS common-law test (behavioral control, financial control, relationship) that governs whether a paid worker is a contractor or employee, and that the misclassification exposure falls on the employer.. That means back federal income-tax withholding, both the employer and employee shares of Social Security and Medicare, and federal unemployment tax, on the deposit schedule that governs every W-2 employer 3Ref 3Internal Revenue Service (2026).Understanding employment taxes.The employer's obligation to withhold and deposit income tax, Social Security, Medicare, and federal unemployment tax on an employee's wages.. Interest and penalties ride on top, and the exposure compounds for each quarter still inside the lookback.

The information-return side matters too. A practice that pays a contractor $600 or more in a year must issue a Form 1099-NEC 4Ref 4Internal Revenue Service (2026).About Form 1099-NEC, Nonemployee Compensation.That payments of $600 or more to a nonemployee for services require a Form 1099-NEC.; missing or inconsistent 1099s tell a reviewer the classification and reporting were loose. Keep payroll records, deposit records, and the worker agreements for at least the retention period the IRS sets for employment-tax records 5Ref 5Internal Revenue Service (2026).Recordkeeping.How long a practice should retain employment-tax and other business records..

What tends to trigger the reclassification

Certain patterns draw the reviewer's eye because they contradict the contractor label. A 1099 clinician who works only for your practice, on your schedule, using your templates and your supervision, reads as an employee no matter what the agreement says 1Ref 1Internal Revenue Service (2026).Independent contractor (self-employed) or employee?.The IRS common-law test (behavioral control, financial control, relationship) that governs whether a paid worker is a contractor or employee, and that the misclassification exposure falls on the employer.. So does an admin worker doing core, ongoing office work rather than a defined project — the w-2 vs 1099 for admin work line is where many solo practices slip first.

Restrictive covenants are their own signal. The restrictive covenants you would impose on a true employee — a non-compete, a long non-solicit — cut against contractor status, because they reflect the ongoing control that defines employment. As of July 2026, the FTC's 2024 rule that would have banned most non-competes was set aside by a federal court, so these covenants remain governed by state law while appeals proceed 6Ref 6Federal Trade Commission (2024).Noncompete Rule.That the FTC's 2024 non-compete rule was set aside in federal court and that non-competes remain governed by state law as of July 2026..

The mirror image inside an S corporation

Solo owners meet the same control question from the other direction. An owner who elects S-corporation tax treatment becomes a shareholder-employee, and the IRS requires reasonable compensation paid as W-2 wages before any profit distributions 7Ref 7Internal Revenue Service (2026).S corporations.That an S-corporation shareholder-employee must take reasonable compensation as W-2 wages before profit distributions.. Paying yourself entirely in distributions to avoid payroll tax is the mirror image of calling an employee a contractor — the same reclassification logic applies, and the fix is the same reasonable, documented wage.

An owner-employee setup also pulls in obligations a pure contractor model avoids: payroll filings, and in most states workers' comp coverage rules that turn on employee status. Price those before you convert, not after.

Building the record before you add anyone

The time to win a classification question is before any audit, when you set the arrangement up. A defensible 1099 relationship looks like one on paper and in practice: a written scope of work, invoices the worker submits, real freedom to set their own methods and take other clients, and no employee-style supervision 1Ref 1Internal Revenue Service (2026).Independent contractor (self-employed) or employee?.The IRS common-law test (behavioral control, financial control, relationship) that governs whether a paid worker is a contractor or employee, and that the misclassification exposure falls on the employer.. Store those documents with your employment-tax records so they are ready if a reviewer ever asks 5Ref 5Internal Revenue Service (2026).Recordkeeping.How long a practice should retain employment-tax and other business records..

Run the classification with your CPA before onboarding a supervisor, a biller, or a treating clinician under the 1099 clinician model, and re-run it whenever the working relationship tightens. If the honest answer is 'employee,' the cheaper path is usually to set up payroll correctly from the first check rather than defend a 1099 later. Where the facts are genuinely mixed is exactly where professional advice earns its fee — and learning the three buckets first makes that conversation shorter.

Common questions

No. The agreement is one relationship factor, but the IRS looks past the paperwork to how the work actually happens — who controls the schedule, the methods, and the tools. A contract that calls someone a contractor while the practice supervises them like staff will not survive the common-law test. Draft the agreement to match a real contractor relationship, then run the arrangement that way.

The practice does. Because the employer is responsible for withholding and depositing employment taxes, a reclassification puts the back withholding, the employer and employee shares of Social Security and Medicare, unemployment tax, interest, and penalties on the practice — not on the worker who was paid gross. That is why the exposure is worth pricing before you rely on a 1099.

Sometimes, but it is harder than practices assume. A clinician who keeps their own panel, sets their own hours, works for several practices, and is not supervised can fit the contractor profile. One who works only for you, on your schedule, under your protocols starts to look like an employee. The facts, not the credential, decide it — review them with your CPA before you commit.

Not exactly. State labor departments and the U.S. Department of Labor apply their own classification standards for wage-and-hour and unemployment purposes, and some are stricter than the IRS common-law test. A worker can be a contractor for one and an employee for another. Treat a favorable federal answer as covering only the federal tax question, and check your state's rule separately.

Filing the form is required when you pay a contractor $600 or more, and failing to file is its own problem — but the 1099 itself does not prove the person is a contractor. It reports the payment; it does not decide the classification. A worker can receive a 1099 and still be reclassified as an employee if the control facts point that way.
