Employee or Contractor? The Federal Rules, and What Getting It Wrong Can Cost You
Many U.S.-based business owners eventually face the same question, regardless of whether their business is located in the CNMI, Guam, any state, or elsewhere in the United States. When you bring someone on to help with the work, do they get treated as an employee or a contractor? It sounds like a paperwork detail, but two separate federal agencies watch this decision closely, and a wrong answer can follow a business owner personally, not just the business, for years.
Guam and the CNMI, while separate from the contiguous United States, mirror its federal tax system almost identically, with specific wage statement and information return forms used to report a worker's pay, each differing by jurisdiction. The mainland uses Form W-2 for employees, Guam uses Form W-2GU, and the CNMI uses Form W-2CM, while contractor payments are generally reported on an information return, such as Form 1099-NEC across all three.
To simplify, this piece refers to these documents collectively as “wage statements” and “information returns,” because the federal worker-classification rules and penalty structure discussed below apply consistently regardless of which jurisdiction-specific form is used. It is important to note that each respective local jurisdiction maintains the right to impose additional requirements beyond the federal rules addressed here.
The labels given to workers go beyond basic paperwork and are more important than most realize.
An independent contractor is, in effect, running their own small business. They generally set their own hours, use their own tools or equipment, and often work for more than one client at a time. Nobody withholds taxes from their pay. Instead, they receive an information return at year's end and are responsible for handling their own income tax and self-employment tax obligations. There are no benefits package that comes with the arrangement, no employer-sponsored health insurance, no paid time off, and no employer contribution to retirement savings.
An employee, by contrast, works under the direction of the business. The employer sets the schedule, dictates how the work gets done, and typically supplies the tools or workspace. In general, employees work for a single employer, and the employer withholds taxes from each paycheck. These withholdings include income tax and the employee's share of Social Security and Medicare. At year's end, the worker receives a wage statement documenting wages paid and taxes withheld. Employees may also be entitled to benefits that contractors typically don't receive, such as health coverage, paid leave, or a retirement match.
How the IRS Determines Worker Classification
There is no single factor that settles the question on its own. The determination requires weighing the full facts and circumstances of the relationship, and the IRS looks at that relationship through three lenses:
Behavioral control asks whether the business directs what the worker does and how they do it. If you dictate hours, methods, or procedures, and can control the specific techniques a worker must use, that points toward an employee relationship. Independent contractors typically have far more latitude to decide how the work actually gets done.
Financial control asks who bears the financial risk. Employees are paid a steady wage or salary regardless of outcome, and the employer usually supplies the tools and materials needed for the job. Contractors, on the other hand, usually invest in their own equipment, cover their own expenses, and are often paid a flat fee per project. Because of that, they can profit or lose money based on their own business decisions in a way that an employee cannot.
Type of relationship looks at whether there's a written agreement, whether the arrangement is ongoing or tied to a single project with a defined end date, and whether the work performed is central to what the business actually does. A worker who has been showing up for years and performing a core function of the business starts to look a lot like an employee, regardless of what the contract calls them or what form they receive at tax time. The more control a business exercises over the methods, timing, and scope of the work, and the more closely the arrangement resembles conventional employment, the stronger the indication that the worker belongs on the payroll as an employee rather than being paid by invoice as a contractor.
Business owners are expected to classify workers correctly, but the IRS makes the final call on the federal tax side of a dispute. Either the business or the worker can file Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding, to request an official ruling. If the balancing factors indicate that a worker labeled as a contractor was actually functioning as an employee, that worker may still be entitled to the legal rights and tax treatment of an employee despite the information return they received, and the employer can become liable for the shortfall.
How the DOL Determines Worker Classification
The U.S. Department of Labor is not a subordinate agency waiting on the IRS's answer. It has its own, independent jurisdiction over worker classification under the Fair Labor Standards Act, which governs minimum wage, overtime, and related protections, and it enforces that jurisdiction on its own schedule and its own investigations, regardless of what the IRS has or hasn't decided. A business can be fully cleared on the tax side and still be squarely in the DOL's crosshairs.
The DOL implements a separate test called the economic realities test, which asks a related but distinct question from the IRS common law test: is the worker genuinely in business for themselves, or economically dependent on this one employer for their livelihood? It considers many of the same underlying facts, control, investment, permanence, and integration into the business, but it weighs them differently, and it is generally regarded as the stricter of the two tests.
It is entirely possible, and not even unusual, for a worker to be correctly treated as a contractor under the IRS test and still be found to be an employee under the DOL's economic realities test. A business that has done the work to be defensible with the IRS can still owe back wages, overtime, and civil penalties to the DOL for the exact same worker relationship. Passing one test is not passing both, and treating them as interchangeable is one of the more common and costly assumptions business owners make.
If the Misclassification Was Not Willful
Even an honest mistake carries a real price tag. If the employer filed the required information returns, the reduced penalty is 1.5% of wages for the failure to withhold income tax, plus 20% of the employee's share of FICA taxes that should have been withheld. If the required information returns were never filed at all, both of those rates double, to 3% of wages and 40% of the employee's FICA share. In either scenario, the employer still owes 100% of the employer's own matching share of FICA taxes. A failure-to-pay penalty of 0.5% of the unpaid liability accrues for each month it remains unpaid, capped at 25% in total, with interest accruing on the full balance from the original due date forward. Separate, per-form penalties apply to each missing wage statement.
None of this requires the IRS to prove the employer meant to break the law. A business that genuinely believed its classification was correct, and was simply wrong, is still on the hook for every figure above, and a business with a pattern of many misclassified workers can watch a routine review turn into a liability with six figures attached before penalties for a related DOL claim are even added on top.
If the Misclassification Was Willful or Fraudulent
Once the IRS believes the misclassification was willful or fraudulent, rather than a good-faith mistake, the entire calculus changes, and not in the employer's favor. The person actually responsible for collecting and remitting withheld taxes, not just the business entity, can be pursued personally under the trust fund recovery penalty, equal to 100% of the unpaid trust fund taxes. That liability follows the individual, survives the business closing its doors, and generally is not discharged in bankruptcy.
The reduced rates under the Voluntary Classification Settlement Program disappear completely. The employer is fully liable for all income and FICA taxes that should have been withheld and paid, with no discount.
Criminal exposure becomes real, not theoretical, and can include up to a year in prison in addition to fines. The per-form penalty for intentional disregard of the wage statement filing requirement climbs to $680 per form, with no annual cap. Additionally, the DOL can impose its own penalties in addition to any the IRS assesses. For repeated or willful minimum wage or overtime violations, the DOL can impose a civil penalty of up to $2,515 per violation, in addition to back wages and liquidated damages equal to those back wages, and willful FLSA violations can carry criminal fines of up to $10,000, with imprisonment possible for a repeat offense.
This is the scenario in which the business is no longer the only thing at risk. Once personal liability and criminal exposure are on the table, the conversation moves from a bookkeeping fix to something that needs to be handled immediately and carefully, ideally before the IRS or the DOL opens a file rather than after.
What This Means for Your Business
Everything above describes the federal analysis, which is the same starting point whether a business operates in Guam, the CNMI, or the mainland, and it's the piece of the puzzle every employer shares regardless of location.
Business owners who realize they've been misclassifying workers do not have to wait for a notice from either agency to fix it. The Voluntary Classification Settlement Program allows eligible employers to reclassify workers as employees going forward, with substantial relief from past federal employment tax liability. The Voluntary Classification Settlement Program allows the disclosing business to settle for ten (10%) percent of what the overall employment tax liability is due on the compensation paid to the workers for the most recently closed tax year, provided the business hasn't already been audited on the classification issue. Coming forward voluntarily and paying 10% is always a better financial and legal position than being caught by an IRS or DOL audit.
If you're not sure how a worker should be classified, don't guess and don't wait. Review the arrangement against the behavioral control, financial control, and relationship factors above, and be honest with yourself about how much direction you're actually exercising day to day. Because both federal agencies can reach different conclusions on the same facts, it's worth confirming your classification against both the IRS standard and the DOL standard before a routine review becomes an expensive one.
