IRS Worker Classification Audits | Kathryn Meyer Law PC

The examiner looks at whether people you paid as independent contractors were legally employees and, if so, how much employment tax you owe for them. Section 530 relief can eliminate those back taxes if you meet its requirements, whatever the workers' true status. If relief does not apply, reduced rates, settlement programs and Tax Court review can still shape the outcome.

These audits touch any business that pays people on Form 1099, including professional firms that use contract lawyers, paralegals or bookkeepers. This page explains the test, the relief rules and the choices you face, as part of Kathryn Meyer's guidance on IRS audits and examinations.

How a classification audit runs, step by step

The letter. The IRS writes to say it will examine your employment tax returns, by mail or in person at your business, an IRS office or your representative's office.
Information returns first. Publication 5146 says the examiner checks early on that you filed all required Forms W-2, 1099-NEC and 1099-MISC, from the period under review to the most recent year, and whether information return penalties apply.
The relationship. The examiner reviews contracts, invoices, how work is assigned and paid, and how similar workers are treated.
Relief and settlement. Section 530 is considered; if it does not apply and workers are found misclassified, a Classification Settlement Program offer may follow.
Time limits. If the assessment deadline is near, you may be asked to sign Form SS-10, which you can sign, restrict or refuse.
Results and appeal. You receive the proposed changes, can go to Appeals, and may later receive Letter 3523, which opens the Tax Court.

How does the IRS decide who is an employee?

The IRS applies the common-law test, which asks how much control and independence exist in the relationship. It groups the evidence into three categories:

Behavioral control: whether the business controls, or has the right to control, what the worker does and how the worker does the job.
Financial control: whether the business controls the business side of the work, such as how the worker is paid, whether expenses are reimbursed, and who provides tools and supplies.
Type of relationship: written contracts, employee-type benefits like a pension plan, insurance or vacation pay, whether the relationship is expected to continue, and whether the work is a key part of the business.

The IRS stresses that there is no set number of factors that makes someone an employee and that no single factor decides it. Working remotely does not change the answer: a remote worker is an employee if you have the right to control what is done and how. Getting it wrong can mean owing employment taxes for those workers, plus penalties and interest.

What is section 530 relief?

Section 530 of the Revenue Act of 1978 can relieve a business of federal employment tax for workers it treated as contractors, without deciding whether they were really employees. IRS Publication 1976 lists three requirements, and all must be met:

Reporting consistency. You filed all required federal returns, including information returns such as Form 1099-NEC for each worker, consistent with treating them as non-employees. Relief is not available for any year or worker for which the required information returns were not filed.
Substantive consistency. You, and any predecessor business, treated the workers and any workers in similar positions as contractors. If you treated a similar worker as an employee, relief is not available.
Reasonable basis. You had a reasonable basis for not treating them as employees, such as reliance on a court case or IRS ruling, a past IRS audit that did not reclassify similar workers, the way a significant segment of your industry treated similar workers, or the advice of a business lawyer or accountant who knew the facts.

A past audit counts only in limited cases: if it began after December 31, 1996, it must have included an employment tax examination of whether the same or similar workers were employees. Relief also does not make the workers contractors for other purposes; the IRS notes a worker can still be found to be an employee, for example through a Form SS-8 determination.

What if the workers are reclassified?

If section 530 does not apply, section 3509 can limit the back taxes on amounts you failed to withhold. Under the statute, liability for income tax withholding is figured at 1.5 percent of wages, and the employee's share of social security and Medicare tax at 20 percent of the normal amount. Those rates rise to 3 percent and 40 percent if you also failed to file the required information returns, unless that failure was due to reasonable cause.

Situation	Income tax withholding owed	Employee share of social security and Medicare owed
Information returns filed for the workers	1.5% of wages	20% of the employee share
Information returns not filed (no reasonable cause)	3% of wages	40% of the employee share
Intentional disregard of withholding rules	Reduced rates not available

The reduced rates are also unavailable if you withheld income tax but not social security and Medicare tax. IRS Publication 5146 explains that these special rates cover the employee share of social security and Medicare taxes and income tax withholding. Penalties may be added as well; see what penalties the IRS can add after an audit.

Can you settle a classification audit?

Sometimes, through one of two IRS programs:

Classification Settlement Program (CSP). Offered during an examination when section 530 relief does not apply and the IRS concludes workers were misclassified. You sign a closing agreement to treat the workers as employees going forward, and your liability for the past is reduced. Publication 5146 says CSP may also be available through Appeals, and that a business that qualifies for section 530 but prefers to treat workers as employees can enter a CSP agreement without giving up its section 530 claim for prior years.
Voluntary Classification Settlement Program (VCSP). For businesses not under an employment tax audit that want to reclassify workers on their own. You pay 10 percent of the employment tax liability that would have been due on the workers' pay for the most recent tax year, computed at the section 3509(a) rates, with no interest or penalties, and the IRS will not audit prior years' classification of those workers. You must have filed all required Forms 1099 for them for the previous three years, and you apply on Form 8952 at least 120 days before you start treating them as employees. A business under an IRS audit other than an employment tax audit can still apply.

Can you challenge the IRS determination in court?

Yes. If classification or section 530 relief is still disputed after the examination and Appeals, the IRS sends Letter 3523, a Notice of Employment Tax Determination Under IRC Section 7436. Under section 7436, the business can petition the U.S. Tax Court without paying first, but the petition must be filed before the 91st day after the notice is mailed. Changing your treatment of the workers to employees while the case is pending cannot be used against you. Alternatively, Publication 5146 explains you can pay a divisible portion, the tax for one worker for one period, claim a refund, and sue in a U.S. District Court or the U.S. Court of Federal Claims.

Timing matters for interest as well. Publication 5146 notes that an interest-free adjustment is not available once the section 7436 notice is issued, but a cash bond deposit made before the notice is treated as an interest-free adjustment. At Appeals, only attorneys, certified public accountants and enrolled agents may represent you; see what happens at an IRS Appeals conference.

What about Form SS-8?

Either a business or a worker can file Form SS-8 to ask the IRS to determine a worker's status. The IRS says a determination may take at least six months. Workers who believe they were misclassified can use Form 8919 to report their share of uncollected social security and Medicare tax.

Workers treated as employees bring the employer's deposit duties with them, explained in when a small law firm has to deposit payroll taxes.

Classification problems also come up when a business is sold, because buyers review payroll exposure; see what tax questions to settle before selling a business.

What changes the answer

Whether you filed the Forms 1099. Missing information returns can defeat section 530 relief for that worker and year, and they double the section 3509 rates absent reasonable cause.
How you treated similar workers. One similar worker on a W-2 can defeat substantive consistency.
The reason you chose contractor treatment. Section 530's reasonable basis can rest on a ruling or court case, a prior audit, industry practice or professional advice.
Whether the workers paid their own income tax. Under sections 3402(d) and 3102(f)(3), you may be relieved of income tax and Additional Medicare Tax not withheld if you show the workers reported and paid it, using Forms 4670 and 4669, though penalties and interest still apply (Publication 5146).
Intent. Intentional disregard of the withholding rules takes the reduced rates off the table.
Timing of your own correction. The Voluntary Classification Settlement Program is open only to businesses not under an employment tax audit.

For example: two contract paralegals

For example, suppose a small firm paid two paralegals $40,000 each on Forms 1099-NEC, while a third paralegal doing similar work was on payroll with a Form W-2. The examiner concludes the firm controlled how and when all three worked. Section 530 relief fails on substantive consistency, because a worker in a similar position was treated as an employee.

If the reduced rates in section 3509 apply, the firm's liability for income tax it did not withhold would be 1.5 percent of the $80,000, or $1,200, and its liability for the paralegals' share of social security and Medicare tax would be 20 percent of the normal amount. Had the Forms 1099 not been filed without reasonable cause, those figures would rise to 3 percent and 40 percent. Whether the Classification Settlement Program could reduce the result further would depend on the facts. This is a hypothetical, not a real case.

Common mistakes in classification audits

Relying on the contract's label. The IRS weighs control and the whole relationship; calling someone a contractor does not settle it.
Skipping Forms 1099. The omission costs section 530 relief and the lower section 3509 rates.
Treating similar workers differently. Mixed treatment undercuts substantive consistency.
Missing the Tax Court window. A petition on a section 7436 notice must be filed before the 91st day.
Assuming a payroll provider shifts the liability. Publication 5146 reminds employers that they remain responsible for the taxes even when payroll is outsourced, with limited exceptions for certified professional employer organizations.

What to do this week

List every worker paid as a contractor in the years under review, with what each did and how each was paid.
Confirm a Form 1099-NEC was filed for each one, and gather copies.
Write down why you chose contractor treatment at the time, and collect any advice, rulings or prior audit letters that support it.
Identify any similar workers treated as employees.
Pull contracts, invoices and correspondence that show how the work was directed.
Calendar any response date in the IRS letter and keep proof of what you send.

Frequently asked questions

Can the IRS look at years other than the one in the letter?

Publication 5146 says the examiner checks information return compliance from the period under examination through the most recent calendar year. Each year's assessment period is separate; see how far back the IRS can audit.

Does filing Form 941-X restart the clock?

No. Publication 5146 says an amended employment tax return, such as Form 941-X, does not affect the period of limitation for assessment.

Can you record the examination interview?

Yes, with your own equipment, if you write to the examiner at least 10 days ahead. Publication 5146 says video recording is not allowed; more on interview rights is in your rights during an IRS audit.

Who can represent the business?

An attorney, accountant, enrolled agent or the paid preparer who signed the return can represent you in the examination with a Form 2848. At Appeals, only attorneys, certified public accountants and enrolled agents may.

Could owners be personally liable for the employment taxes?

Possibly. Withheld taxes that are not paid over can lead to the trust fund recovery penalty, which is assessed against responsible people personally.

How long does a Form SS-8 determination take?

The IRS says at least six months. It answers a status question; it does not resolve an audit already under way.

Preparing for a classification audit

The strongest defenses are built from records you already have: contracts, invoices, 1099 filings, and the reasons you chose contractor treatment when you did. Kathryn Meyer can evaluate section 530 relief, the 3509 rates and the settlement programs before you commit to an answer.
