Score the misclassification risk of treating a worker as a 1099 contractor using IRS common-law control factors, and compare the true cost of a W-2 employee versus a 1099 contractor. Avoid back taxes, penalties, and audits with a clear, instant assessment.
IRS control test + cost compare
Misclassifying an employee as an independent contractor is one of the most expensive mistakes a U.S. business can make. If the IRS or a state agency reclassifies your 1099 worker as a W-2 employee, you can owe back payroll taxes, the worker's unpaid FICA, penalties, and interest — plus potential overtime, benefits, and unemployment liabilities. The savings of "just 1099-ing" someone disappear fast.
The IRS uses a common-law control test across three categories: behavioral control (do you direct how, when, and where the work is done?), financial control (who provides tools, can the worker profit or loss, do they serve other clients?), and the relationship (is it ongoing, are benefits provided, is the work core to your business?). The more control you exert, the more the worker looks like an employee. This tool scores those factors into a risk level, then compares the real cost of a W-2 hire (wages + ~7.65% employer FICA + unemployment + benefits) against a straight 1099 fee.
Setting hours, methods, and training points strongly toward employee status.
Providing tools and a steady wage (vs invoices and profit/loss) signals an employee.
Ongoing, exclusive, core-to-business work looks like employment, not a contract gig.
Reclassification brings back taxes, penalties, and interest — far more than payroll tax saved.
Misclassifying employees as independent contractors is one of the costliest mistakes a U.S. business can make, triggering back payroll taxes, penalties, and interest. That is why "W2 vs 1099," "employee vs independent contractor," and "worker misclassification penalties" are searched by employers nationwide. This calculator scores your misclassification risk using the IRS common-law control factors and compares the true cost of a W-2 hire against a 1099 contractor.
The IRS weighs behavioral control, financial control, and the relationship to decide status — but several states, including California, apply the stricter ABC test that presumes employee status unless three conditions are met. The more control you exert over how, when, and where the work is done, the more likely the worker is an employee. Check the factors above before you issue a 1099.
A business pays a worker $60,000 a year, sets their hours, directs how the work is done, and provides training — four of nine factors point to employee status. The risk gauge flags a moderate-to-high misclassification risk, and the true W-2 cost (about $60,000 plus employer FICA, unemployment, and ~15% benefits) is compared against the straight 1099 fee.
U.S. employers, small business owners, HR and finance teams, startups, and agencies deciding whether to hire a worker as a W-2 employee or a 1099 independent contractor and assessing IRS and state ABC-test risk.
