You Classified a Therapist as 1099 and Now You’re Not Sure: How to Fix It

Most agency owners don’t discover a classification problem by reading the IRS common-law test. They discover it when a therapist who stopped taking visits files for unemployment, and a state agency sends a notice asking why this person wasn’t on payroll.

If you’re reading this with that letter in hand, or with a quieter suspicion that one of your 1099 therapists looks a lot like an employee, this page is the orderly version of what to do. It is not a reason to panic, and it is definitely not a reason to start rewriting old paperwork.

How Classification Problems Actually Surface

First: What Not to Do

• Don’t backdate or rewrite old agreements. Altering records after an inquiry begins converts a civil tax disagreement into something far worse. Whatever your files say today, that is what they say.
• Don’t ask the therapist to sign something confirming they were a contractor. A signed agreement has never been decisive — the IRS looks at how the relationship actually worked, not what the parties called it — and a document procured after the fact reads badly.
• Don’t file a Form SS-8 yourself as a reflex. A business can file one, but you’re inviting a formal determination. Get advice on whether that serves you before volunteering.
• Don’t stop filing 1099s. Whatever happens next, your reporting history matters enormously, as the next two sections show.

Section 530: The Safe Harbor Most Agencies Don’t Realize They Need

Section 530 of the Revenue Act of 1978 lets a business keep treating workers as contractors — and escape back employment taxes — even when the IRS would otherwise classify them as employees. It is the most important protection in this area, and it requires all three of the following:

• Reasonable basis. You had a defensible reason for the treatment: judicial precedent or IRS rulings, a prior IRS audit that didn’t object, a long-standing recognized practice in a significant segment of your industry, or other reasonable grounds such as written advice from a qualified professional.
• Substantive consistency. You treated that worker — and every substantially similar worker — as a contractor. If half your PTs are on payroll and half are on 1099 doing identical work, this prong is a serious problem.
• Reporting consistency. You filed all required Forms 1099 for those workers, for all relevant periods.

That last one is where agencies lose protection they would otherwise have had. Skipping a 1099 because a per-diem therapist only worked a few weekends can forfeit Section 530 relief for that worker entirely. File the forms, every year, for everyone required — our 1099-NEC year-end checklist walks through who needs one under the 2026 rules.

What It Costs If the IRS Reclassifies

If reclassification happens and the misclassification was not intentional, the employer’s liability is computed under reduced rates in Internal Revenue Code section 3509 rather than the full amount that would have been withheld:

Under section 3509(a), income tax withholding is computed at 1.5% of wages and the employer’s liability for the worker’s share of FICA is computed at 20% of that share, plus the entire employer share. Failing to file the information returns roughly doubles those components. On $200,000 of cumulative payments to one therapist, that spread is about $6,000 — for paperwork that costs nothing to file.

Two important limits: these reduced rates are not available where the misclassification was intentional disregard rather than an honest judgment, and interest and penalties can apply on top. State unemployment and workers’ compensation exposure is entirely separate from the federal number.

The Voluntary Route: VCSP

If you’ve concluded on your own that workers should be employees going forward, the IRS Voluntary Classification Settlement Program lets you make that change prospectively with partial relief from federal employment taxes. You apply on Form 8952. The core requirements:

VCSP is prospective: it changes the future and settles the past at a reduced amount. It is a real option for an owner who has looked honestly at the relationship and concluded it’s employment — but it is a decision to make with a professional, not from a web page.

Your State Is a Separate Problem

Federal relief does not bind your state. Several states apply an ABC test for unemployment insurance and sometimes for wage law, which is materially harder to satisfy than the federal common-law test — typically requiring that the worker be free from control, perform work outside the usual course of the hiring entity’s business, and be independently established in that trade. That middle prong is the one that bites therapy staffing agencies, because supplying therapy visits is the agency’s usual course of business.

Translation: a relationship that survives the IRS test can still fail a state test. If you operate in more than one state, you may genuinely have different right answers in different states.

What to Do This Month

• Inventory the relationship honestly. Who sets the schedule, who can refuse a visit, who supplies the tools, is there an exclusivity expectation, do they work for other agencies, is pay per visit or per hour against a set schedule? Write down the real answers, not the agreement’s answers.
• Confirm every 1099 was filed for every contractor for every year. If one is missing, talk to your CPA about correcting it — it’s the cheapest protective step available to you.
• Fix the forward-looking behaviors that read as control: mandatory meetings, set hours, agency-dictated documentation methods beyond what payers require, restrictions on working elsewhere.
• Get advice before you respond to any notice. A state unemployment determination answered casually can become the factual record everyone else relies on.

What a Defensible Contractor Relationship Looks Like

For agencies whose model genuinely is contract therapy — and most home health therapy staffing is — the relationship holds up best when the facts are consistently contractor-like: the therapist can decline visits, sets their own daily route and hours, carries their own license and liability coverage, works for more than one agency, is paid per visit rather than a salary against a required schedule, and isn’t trained by you in how to practice. Our classification guide walks through the IRS’s three categories of evidence in detail, and the cost comparison shows why “contractors are cheaper” is rarely the reason to choose it anyway.

One practical note: clean, consistent records of what each therapist was paid, per visit, per period, are useful in exactly this situation. An owner who can produce a complete per-contractor payment history in minutes is in a far better position than one reconstructing it from bank statements — which is one of the quieter arguments for keeping contractor payment records in one system rather than in spreadsheets.
