Frequently Asked Questions

Advanced How much more revenue do I need as a contractor vs my employee salary?
As a rule of thumb, contractors need 1.35x–1.55x the equivalent salary to match total employee compensation. A $100K salary with typical benefits (health, 401k match, PTO) usually requires $135K-$155K in contract revenue to break even. Use the Break-Even Revenue stat in the 6-metric grid to see your specific number based on your inputs.
Basics What is the self-employment tax and how is it calculated?
Self-employment tax is 15.3% applied to 92.35% of net self-employment income (revenue minus business deductions). It covers both the employee (7.65%) and employer (7.65%) shares of Social Security and Medicare. Half of the SE tax is deductible from your federal income tax, partially offsetting the impact. On $100K net income: $100K × 92.35% × 15.3% = $14,130 SE tax.
Basics What is the QBI deduction and does every contractor qualify?
The Qualified Business Income (QBI) deduction under IRC Section 199A allows most self-employed individuals to deduct up to 20% of their qualified business income. Most contractors qualify, but there are income phase-outs for "specified service trades or businesses" (SSTB) — which includes consultants, attorneys, financial advisors, and similar professions — above $197,300 (single) / $394,600 (married) in 2024. Contractors below these thresholds generally receive the full 20% deduction.
Strategy When should a contractor elect S-Corp tax treatment?
S-Corp election typically becomes financially worthwhile when your net self-employment income exceeds approximately $50,000/year. The strategy: elect S-Corp status, pay yourself a reasonable salary (typically 50-70% of profits, subject to FICA), and take remaining profits as shareholder distributions (not subject to SE tax). At $100K net income with a $65K salary, you'd save SE tax on $35K × 15.3% = ~$5,355. After $2,500 in additional accounting costs, the net savings is ~$2,855/year. At $200K+ income, savings typically exceed $10,000/year.
Basics How do contractors pay taxes? What are the quarterly deadlines?
Contractors must pay estimated quarterly taxes to avoid IRS penalties. The 2025 deadlines are: Q1 (Jan-Mar) due April 15; Q2 (Apr-May) due June 16; Q3 (Jun-Aug) due September 15; Q4 (Sep-Dec) due January 15, 2026. Pay at least 100% of your prior year total tax liability (or 110% if prior year AGI exceeded $150,000) to avoid the underpayment penalty. Most contractors set aside 30-35% of each invoice payment.
Advanced Can contractors deduct health insurance premiums?
Yes. Self-employed individuals can deduct 100% of health insurance premiums for themselves and their families as an "above-the-line" deduction on Schedule 1 of Form 1040. This reduces your adjusted gross income directly. The deduction is limited to your net self-employment profit and is not available if you were eligible for employer-subsidized coverage through a spouse's plan during any month.
Basics What retirement accounts can contractors contribute to, and what are the limits?
Contractors have several powerful options: (1) SEP-IRA: contribute up to 25% of net SE income, maximum $69,000 in 2024 — simple to set up; (2) Solo 401k: contribute up to $23,000 as the "employee" plus 25% of net SE income as the "employer," maximum $69,000 total — allows Roth contributions and loans; (3) SIMPLE IRA: up to $16,000 plus 2% employer contribution. These contribution limits are far higher than the $23,000 employee 401k limit, making contractor retirement savings potentially much more powerful.
Basics What is the misclassification risk and how can I protect myself?
Worker misclassification occurs when someone doing employee-like work is classified as an independent contractor. The IRS uses three categories: Behavioral Control (who controls how/when work is done), Financial Control (who provides tools, who risks profit/loss), and Type of Relationship (written contracts, permanency, integration into core business). To protect yourself: use written contracts specifying deliverables not hours, work for multiple clients, use your own equipment, set your own methods, and maintain business records. If misclassified by an employer, file IRS Form SS-8 to request a determination.
Basics How do I value health insurance when comparing offers?
Get quotes from healthcare.gov (ACA marketplace) or your state exchange for your age, location, family size, and desired plan tier before accepting a contractor offer. Compare the actual monthly premium to what you pay as an employee (your payroll deduction, not the total premium). For a 35-year-old family, marketplace family coverage can cost $1,200-$2,000/month vs. $400-$800/month employee contribution — a $10,000-$15,000 annual difference that must be built into your contractor rate.
Advanced What business expenses can contractors deduct?
Contractors can deduct ordinary and necessary business expenses: home office (actual expenses or simplified $5/sq ft method), computer/equipment, software subscriptions, business-use vehicle (actual expenses or mileage at $0.67/mile in 2024), professional development and courses, business-related books and publications, professional association dues, business insurance, accounting/legal fees, business meals (50%), advertising and marketing, and business phone/internet (business-use portion). Keep receipts and maintain clear records separating personal from business use.
Strategy Is it better to work as a contractor or employee financially?
It depends on your specific situation. Contractors generally win financially when: (1) the rate is 40%+ above equivalent salary, (2) billable utilization stays above 80%, (3) you have multiple clients, (4) you can effectively use business deductions, and (5) you're in a low-benefit industry. Employees generally win when: (1) employer benefits are very comprehensive and valuable, (2) the rate premium is below 30%, (3) you need income stability, or (4) you're in a high-benefit industry. Use the 6-stat grid and Scenario Analysis tab to compare your specific situation.
Basics What is a W-2 employee burden rate?
The burden rate is the ratio of total employer cost to base salary. Employers pay: base salary + employer FICA (7.65%) + FUTA (0.6% on first $7K) + SUTA (~2.5% on first $12K) + health insurance + 401k match + other benefits. A $100K salary typically has a total burden of $125K-$145K, giving a multiplier of 1.25x-1.45x. When comparing contractor cost to employee cost, employers should compare the contractor's invoice rate to this fully-loaded burden, not just the base salary.
Advanced Can I switch between contractor and employee status?
Yes, though there are considerations. Switching from employee to contractor: consider COBRA for health insurance continuity (18 months), immediately open a SEP-IRA or Solo 401k, set up a separate business bank account, register your business structure (LLC recommended), and ensure a 3-6 month emergency fund before making the switch. Switching from contractor to employee: note that contractors who were previously full-time W-2 employees at the same company for 2+ years face higher IRS misclassification scrutiny and should use a clear written contract documenting the change in relationship.
Basics How does the sensitivity matrix in Scenario Analysis work?
The sensitivity matrix shows how the net financial advantage changes across different employee salary levels (rows) and contractor revenue multipliers (columns). Each cell shows the dollar advantage (positive = contractor ahead, negative = employee ahead) using your current benefit and deduction inputs. Your current salary/revenue combination is highlighted with a bold border. This helps you see how sensitive the decision is to income levels — whether a small rate change or salary increase would flip the winner.
Basics What does the Career Projector show?
The Career Projector shows cumulative net income over 10 years, assuming both salary and contractor revenue grow at the same rate (adjustable with the slider, default 3%/year). It helps visualize whether a current contractor advantage compounds over time or whether an employee's growing salary+benefits package eventually catches up. The Year-by-Year table can be toggled between annual and cumulative views and exported to CSV for detailed analysis.

Formula & Methodology

Employee Total Economic Value
Value = Salary − 401k − FICA(7.65%) − Fed Tax − State Tax + Health Value + Match + Benefits
Total value includes both cash take-home and non-cash employer-provided benefits at their full annual value.
Contractor Net Income
Net = Revenue − Deductions − QBI(20%) − SE Tax(92.35%×15.3%) − Fed Tax − State Tax
SE tax covers both halves of FICA. Half SE is deductible from income. QBI deduction (IRC 199A) reduces taxable income by up to 20%.
Break-Even Revenue

Contractor vs Employee: The Complete Financial Analysis

The Real Cost of Self-Employment Tax

When you become a contractor, you immediately face a 15.3% self-employment tax on 92.35% of your net income — covering both the employee and employer shares of FICA. On $100,000 of net SE income, that's roughly $14,130 in SE tax alone. This is why contractors typically need 1.4-1.6x an equivalent salary just to break even.

The QBI Deduction Changes the Math

Since 2018, most self-employed individuals can deduct up to 20% of qualified business income under IRC Section 199A. For a contractor with $100K in net business income, this could reduce taxable income by $20,000, saving $4,400-$6,400 in federal income tax depending on bracket. This significantly narrows the gap between contractor and employee arrangements.

The Hidden Value of Employee Benefits

A $100,000 salary can easily represent $125,000-$140,000 in total compensation when you add employer FICA matching ($7,650), health insurance ($8,000-$20,000/yr), 401k match (3-6% of salary), paid time off (15 days = ~$5,769 at that salary), and other benefits. Contractors must price all of this into their rate.

When S-Corp Election Makes Sense

Once net self-employment income consistently exceeds $50,000/year, an S-Corp election can meaningfully reduce SE taxes. The strategy: pay yourself a "reasonable salary" (typically 50-70% of net income, subject to FICA) and take remaining profits as shareholder distributions (no SE tax). The savings scale with income — at $150K net SE income, this can save $8,000-$12,000 annually after accounting for $2,000-$2,500 in additional accounting costs.

Misclassification Risk

The IRS uses a three-category test — Behavioral Control, Financial Control, and Type of Relationship — to determine worker status. Contractors should set their own hours, provide their own tools, work for multiple clients, and risk profit/loss. Misclassification penalties for employers include back FICA taxes, failure-to-deposit penalties, and potential ERISA liability. Always use written contracts.
