Cost Comparison: Contractor vs. Employee at $100,000
The true cost of an employee goes beyond salary: employer payroll taxes, the employer's share of health premiums, a retirement match and workers compensation all sit on top. Every input below is visible so you can substitute your own and redo the arithmetic. On these inputs the uplift is about 22%, not the 30 to 40% figure often quoted, because two things that inflate the usual version of this comparison have been left out deliberately. See the notes beneath the table.
Contractor at $100,000
Employee at $100,000
Two things this table deliberately does not do
It does not charge the whole health premium to the employer. The KFF 2025 Employer Health Benefits Survey puts the average annual single-coverage premium at $9,325, of which workers contributed $1,440 on average. The employer share is therefore about $7,885, and that is the figure used above. Comparisons that put the full $9,325 in the employer column overstate the gap by the worker's own payroll deduction.
It does not add paid time off as a separate line. For a salaried employee, PTO is already inside the $100,000: you pay the same salary whether or not the leave is taken, so adding a 15-day "PTO cost" on top counts the same money twice. PTO is a genuine incremental cost only where the worker is paid hourly and leave is paid on top of hours worked. This is the most common error in contractor-versus-employee cost tables, and it was in ours until we recomputed it.
This is our own model, not a published benchmark. Sourced inputs: FICA employer share 7.65% and FUTA of $42 to $420 per employee (IRS); average single-coverage premium $9,325 and average worker contribution $1,440 (KFF 2025 Employer Health Benefits Survey, checked 1 October 2026). Estimated inputs you should replace with your own: the $1,200 combined FUTA and state unemployment figure, the 4% retirement match, and the $1,200 workers compensation allowance. Workers compensation rates in particular vary enormously by industry classification and state. Note also that a contractor charging $100,000 is not the same engagement as an employee on a $100,000 salary; contractors typically price their own overhead and self-employment tax into the rate, so the honest comparison is between two quoted numbers, not between a salary and a rate.
10 Differences in Detail
1.Tax Treatment and Withholding
Contractor
Contractor pays own self-employment tax (15.3%: 12.4% Social Security + 2.9% Medicare). Receives Form 1099-NEC. Makes quarterly estimated payments. Company withholds nothing.
Employee
Employer withholds income tax, FICA (7.65% employee share), and pays matching FICA (7.65% employer share). Employee receives W-2. Total employer tax burden: 7.65% of wages plus FUTA ($42 to $420 per employee per year).
Financial Impact
For a $100,000 engagement, the employer's additional tax cost for an employee is approximately $7,650 in FICA matching alone, plus $420 FUTA, plus state unemployment tax ($400 to $2,000+ depending on state). This does not include benefits overhead.
What Your Agreement Needs to Say
Contractor agreement: include a tax obligations clause stating the contractor is responsible for all self-employment taxes. Employee agreement: no such clause needed since the employer withholds automatically.
2.Benefits and Insurance
Contractor
No benefits. Contractor arranges their own health insurance, retirement savings, disability, and liability coverage. This is a defining characteristic of contractor status.
Employee
Employer typically provides health insurance (average cost $9,325/year for single, $26,993/year for family in 2025 per the KFF Employer Health Benefits Survey), 401(k) with match (3 to 6% of salary), PTO (10 to 20 days), workers compensation, and disability insurance.
Financial Impact
On the inputs in our cost model below, a $100,000 salary carries roughly $21,900 of employer payroll tax, health premium share, retirement match and workers compensation, for a total around $121,900. A contractor invoicing $100,000 costs $100,000 plus your portion of any agreed expenses. Substitute your own benefit structure; the point is the shape, not our numbers.
What Your Agreement Needs to Say
Contractor agreement: explicitly state 'Contractor is not eligible for any Company benefits.' Providing benefits to a contractor is one of the strongest indicators of misclassification.
3.Work Schedule and Location Control
Contractor
Contractor controls when, where, and how they work. Company specifies deliverables and deadlines, not daily schedules. Contractor may work from their own office, home, or any location.
Employee
Employer sets work hours (e.g., 9 to 5, Monday to Friday), may require on-site presence, monitors attendance, and controls the method of work. Even with flexible schedules, the employer retains the right to set them.
Financial Impact
The IRS considers schedule control one of the most important behavioral control factors. If you require a contractor to work specific hours at your office, you are creating evidence of an employment relationship.
What Your Agreement Needs to Say
Contractor agreement: specify deliverables and deadlines, never work hours. Include language like 'Contractor shall determine the time, place, and manner of performing Services.' Employee agreement: may include expected hours and location.
4.Tools and Equipment
Contractor
Contractor provides their own tools, software, equipment, and workspace. The contractor's investment in their own trade is evidence of financial independence.
Employee
Employer provides all necessary tools: computer, software licenses, office space, phone, and supplies. Employee is not expected to invest in the tools of the employer's business.
Financial Impact
The IRS treats a significant investment by the worker in their own equipment and facilities as evidence of contractor status, while declining to attach any dollar threshold to it. What matters is the direction of travel, not a figure: providing a contractor with a company laptop, email address and desk undermines the classification regardless of what the kit costs.
What Your Agreement Needs to Say
Contractor agreement: include a clause stating 'Contractor shall provide all tools, equipment, and materials necessary to perform the Services at Contractor's own expense.' Employee agreement: no such clause needed.
5.Intellectual Property Ownership
Contractor
Contractor owns all work product by default under 17 U.S.C. Section 101 unless the agreement includes an explicit IP assignment clause. Work-for-hire doctrine has limited applicability for independent contractors.
Employee
Employer typically owns all work product under the work-for-hire doctrine. Employee inventions created within the scope of employment belong to the employer automatically in most states.
Financial Impact
This is the most commonly misunderstood difference. Without an IP assignment clause, a contractor who builds your software, designs your logo, or writes your content owns the copyright, and can license the same work to your competitors. Recovering the rights afterwards means buying them from someone who knows you need them, and until you do you cannot register the copyright or sue an infringer.
What Your Agreement Needs to Say
Contractor agreement: MUST include an IP assignment clause with backup assignment language. Include pre-existing IP carve-outs. Employee agreement: work-for-hire typically applies automatically, but many companies include invention assignment clauses for additional protection.
6.Termination Rights and Notice
Contractor
Governed by the contract terms. Typically requires 30 days written notice for termination without cause. For-cause termination may be immediate with specific triggers defined in the agreement.
Employee
At-will employment (in 49 states) allows either party to terminate at any time for any legal reason, with or without notice. Montana requires good cause for termination after a probationary period.
Financial Impact
Contractor termination is a contractual matter. If you terminate without following the contract's terms, you may owe the full contract value. Employee termination is an employment law matter with protections against discrimination, retaliation, and wrongful termination.
What Your Agreement Needs to Say
Contractor agreement: specify notice periods, for-cause triggers, final payment terms, and work product handoff requirements. Employee agreement: typically references at-will status or includes a notice period for senior roles.
7.Non-Compete Enforceability
Contractor
Non-competes face heightened scrutiny for contractors because restricting their ability to work for others undermines their independent status. Courts in many states will void a non-compete that is inconsistent with contractor classification.
Employee
Non-competes are more commonly enforced for employees, subject to state law. Approximately 18% of US workers are currently bound by a non-compete. California, Oklahoma, North Dakota, and Minnesota ban them for both employees and contractors.
Financial Impact
A broad non-compete in a contractor agreement creates a paradox: if the contractor cannot work for others, the IRS may view the exclusivity as evidence of employment. Focus on non-solicitation of specific clients rather than broad non-competes.
What Your Agreement Needs to Say
Contractor agreement: use non-solicitation clauses targeting specific client relationships and employees, not broad competitive restrictions. Employee agreement: non-competes are more defensible but still must be reasonable in scope, duration, and geography.
8.Liability and Indemnification
Contractor
Contractor is typically liable for their own negligence. Mutual indemnification clauses are standard. Contractor carries their own insurance (general liability, professional liability/E&O).
Employee
Employer is vicariously liable for employee actions within the scope of employment under the doctrine of respondeat superior. Employer carries workers compensation and employer's liability insurance.
Financial Impact
With a contractor, your liability is limited to what the contract provides (plus any negligent hiring claims). With an employee, you are liable for their on-the-job actions even if you did not authorize them. This is a significant advantage of the contractor model for risk management.
What Your Agreement Needs to Say
Contractor agreement: include mutual indemnification, liability caps, and insurance requirements. Employee agreement: indemnification is less common; focus on confidentiality, invention assignment, and non-solicitation.
9.Dispute Resolution
Contractor
Governed by the contract's dispute resolution clause. Best practice: mediation-first, then binding arbitration. Venue and governing law specified in the agreement.
Employee
Subject to employment law protections. Many employers use mandatory arbitration agreements (upheld by the Supreme Court in Epic Systems v. Lewis, 2018). Employees retain access to EEOC, state labor boards, and federal courts for discrimination claims.
Financial Impact
Contractor disputes are fundamentally contract disputes, decided on what the agreement says. Employee disputes bring in employment law and its additional protections (anti-discrimination, FLSA, FMLA and so on) which do not apply to contractors, so the range of claims available to an employee is wider and the forums more numerous. We do not publish average cost figures for either, because the credible ones do not exist at this level of generality.
What Your Agreement Needs to Say
Contractor agreement: specify mediation-first, then AAA arbitration, with a defined venue. Employee agreement: consider mandatory arbitration with class action waiver (subject to state law restrictions).
10.Duration and Renewal
Contractor
Defined term with specific start and end dates. Project-based engagements end upon deliverable completion. Renewals require mutual agreement and often a new or amended contract.
Employee
Ongoing, indefinite relationship. No defined end date. The permanency of the relationship is evidence of employment status under both IRS and DOL tests.
Financial Impact
The IRS considers the permanency of the relationship a key factor. A contractor who has worked for you for 5 years with automatic renewals and no project-based scope looks more like an employee. Structure engagements with clear terms: 3-month, 6-month, or project-based, with explicit renewal processes.
What Your Agreement Needs to Say
Contractor agreement: always include an end date or project completion trigger. For ongoing engagements, use 6 to 12 month terms with renewal provisions. Employee agreement: typically states at-will employment without a defined end.
When to Convert a Contractor to an Employee
Sometimes a contractor relationship naturally evolves toward employment. Recognizing when to convert is critical for avoiding retroactive reclassification penalties.
The engagement has lasted over 12 months with automatic renewals
Long-term, indefinite engagements with no project-based scope are a strong indicator of employment. If you need this person indefinitely, hire them.
You are controlling their daily schedule and work location
If you need the worker at your office from 9 to 5, that level of behavioral control is employment. Contractors control their own schedule.
The contractor works exclusively for you
Exclusivity is one of the strongest employment indicators. If the contractor has no other clients, the IRS views this as economic dependence.
You provide all tools, equipment, and workspace
When the worker's only investment is their labor and you supply everything else, the financial independence that defines contractor status is absent.
The work is identical to what your employees do
A contractor doing the same job as your employees, sitting next to them, with the same schedule, is an employee in everything but name.
If you recognize these signs, consider the IRS Voluntary Classification Settlement Program (VCSP), which allows you to reclassify workers prospectively with reduced penalties. See our misclassification risk page for details.
