How is a worker classified?
By the degree of control and independence: behavioral control over how the work is done, financial control such as investment, expenses and opportunity for profit, and the relationship, such as permanence and benefits. A worker who follows your schedule, uses your tools and works only for you is likely an employee, whatever the contract says. Some states use a stricter ABC test. See independent contractor or employee.
Contracts help, but the facts decide.
What is the exposure?
| Item | Notes |
|---|---|
| Federal income tax that should have been withheld | Reduced rate if the error was not intentional |
| Employee share of Social Security and Medicare | Reduced rate if not intentional |
| Employer share of Social Security and Medicare | In full |
| Federal and state unemployment tax | In full |
| Interest and penalties | Including late deposit penalties |
| State and labor law liabilities | Overtime, minimum wage, benefits, workers' compensation |
What are the reduced rates?
Where the misclassification was not intentional disregard, section 3509 sets the employer's liability for the employee-side taxes at reduced rates: 1.5% of wages for income tax withholding and 20% of the employee's share of Social Security and Medicare if Forms 1099 were filed, doubling to 3% and 40% if they were not. The employer share is still due in full. Filing 1099s for contractors therefore matters even if classification is later challenged.
What is the Voluntary Classification Settlement Program?
An IRS program that lets a business start treating workers as employees going forward and pay 10% of the employment tax liability that would apply to the most recent tax year under the reduced rates, with no interest or penalties and no audit of earlier years on the issue. To qualify, the business must have consistently treated the workers as contractors, filed the required Forms 1099 for them for the previous three years, and not be under an employment tax audit. Apply with Form 8952 well before you want to begin treating the workers as employees.
What is section 530 relief?
A safe harbor that stops the IRS from reclassifying workers for federal employment taxes if the business had a reasonable basis for contractor treatment, such as industry practice, a prior audit or a court ruling, treated similar workers consistently, and filed all required 1099s. It can be raised in an audit.
Keep the evidence for it.
How do you fix misclassification?
Review each worker relationship
Against the federal and state tests.
Decide on the approach
Reclassify, settle through the program, or rely on safe harbor where it fits.
Put reclassified workers on payroll
With W-4s and state registrations.
Address state exposure
Some states have their own settlement routes.
How large can the exposure be?
A business paid three workers $50,000 each in a year as contractors and filed Forms 1099. If reclassified as employees without intentional disregard, the federal bill for that year would include roughly $2,250 of withholding at 1.5%, about $2,295 for the employee share of Social Security and Medicare at 20% of the usual amount, $11,475 for the employer share, and federal unemployment tax, before interest, penalties and state amounts. Over three open years the total multiplies. Under the settlement program, the business would instead pay a fraction of one year's reduced amount.
Can you ask the IRS to decide?
Yes. Form SS-8 asks the IRS for a determination of a worker's status. Either the business or the worker can file it, and the process can take many months. Workers who believe they were misclassified can file Form 8919 to pay only the employee share of Social Security and Medicare.
