Contractor vs Employee Calculator

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 halves of FICA (Social Security and Medicare) that are normally split with an employer. On $100,000 of net SE income, that's roughly $14,130 in SE tax before any income tax applies. As a W-2 employee, your employer pays half of FICA (7.65%) silently behind the scenes; as a contractor you see the entire 15.3% as a line-item tax on Schedule SE, which psychologically hurts more even though the total tax burden is similar once you account for the employer-paid portion.

The Social Security portion of SE tax (12.4%) applies only to the first $168,600 of net earnings in 2024, then stops — so contractors earning above that threshold see their marginal SE tax rate drop to just 2.9% (Medicare only) on income above the wage base. This is why high-earning contractors sometimes come out ahead of high-earning employees even before QBI deduction: the SS wage base creates a built-in tax cap. Half of your total SE tax is deductible above-the-line on your federal return, which partially offsets the burden. Factor this into break-even analysis by computing SE tax on your specific income profile rather than applying a flat 15.3% to the full amount.

Since 2018, most self-employed individuals can deduct up to 20% of qualified business income (QBI) under IRC Section 199A, a provision of the Tax Cuts and Jobs Act that dramatically improved the tax math for contractors relative to employees. For a contractor with $100K in net business income, the QBI deduction reduces taxable income by $20,000, saving $4,400–$7,400 in federal income tax depending on marginal bracket. This single deduction significantly narrows (and in some cases eliminates) the gap between contractor and employee tax burdens.

QBI has income-based phase-outs that especially affect "specified service trades or businesses" (SSTBs) — a category that includes consultants, attorneys, accountants, financial advisors, and similar professional services. For 2024, SSTB contractors phase out the full QBI deduction between $197,300–$247,300 (single) or $394,600–$494,600 (married filing jointly). Above those upper thresholds, SSTB professionals get zero QBI deduction, which significantly changes the math for high-earning consultants. Non-SSTB contractors (software developers, engineers, trades, creative professionals in some cases) keep the full deduction above those thresholds subject to separate limits based on W-2 wages paid and qualified property. Check your specific classification with a tax professional because misapplying QBI costs thousands.

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/year for family coverage), 401k match (typically 3–6% of salary, worth $3,000–$6,000), paid time off (15 days = roughly $5,770 at that salary), and miscellaneous benefits like life insurance, disability coverage, employee assistance programs, and commuter benefits. Contractors must price all of this into their rate if they want equivalent take-home after accounting for self-funded equivalents.

Health insurance is typically the single biggest benefit gap. Marketplace family coverage can cost $1,200–$2,000/month ($14,400–$24,000/year) — far more than the $100–$500/month employee contribution on employer plans. Retirement match is the second-biggest underappreciated benefit because it's essentially free money: a 6% match on $100K salary is $6,000/year, and losing that match for 30 years of a career costs over $500K in foregone compounded retirement savings. Paid time off, disability insurance, and employer-subsidized life insurance round out the gap. Quantify every benefit at its fair-market replacement cost when comparing offers — "total compensation" numbers that only count salary plus health are systematically understated.

Once net self-employment income consistently exceeds roughly $50,000/year, electing S-Corp tax treatment on an LLC or corporation can meaningfully reduce SE taxes. The strategy: pay yourself a "reasonable salary" (typically 50–70% of net income, subject to FICA on both sides) and take remaining profits as shareholder distributions (not subject to SE tax at all). The savings scale with income — at $150K net SE income, a well-structured S-Corp can save $8,000–$12,000 annually after accounting for $2,000–$3,000 in additional accounting, payroll service, and state franchise tax costs.

The "reasonable salary" requirement is real and the IRS enforces it — paying yourself $20K salary on $200K of distributions will get challenged in an audit because the salary doesn't match market rates for the services performed. Use Bureau of Labor Statistics median wage data or industry salary surveys to justify your salary level, and document the rationale in corporate records. Below $50K in annual net income, the S-Corp administrative overhead (payroll processing, separate tax return, state filings, workers' comp where required) typically exceeds the tax savings, so it's not worth electing. Above $250K in net income, the savings become substantial enough that most tax advisors recommend it automatically. Work with a CPA to model the specific break-even for your state and income level before filing Form 2553 to elect S-Corp status.

The IRS uses a three-category test — Behavioral Control (who directs how and when work is done), Financial Control (who provides tools, who risks profit/loss, how payment is structured), and Type of Relationship (written contracts, permanency, benefits, integration into core business) — to determine whether a worker is properly classified as an employee or independent contractor. Contractors should set their own hours, provide their own tools, work for multiple clients, carry their own insurance, and genuinely risk profit or loss on the engagement. Workers who report to a specific manager, work fixed hours, use company equipment, and have no other clients look like employees regardless of the 1099 label on the paycheck.

Misclassification penalties for employers include back FICA taxes, failure-to-deposit penalties, state unemployment insurance contributions, workers' comp premiums, and potential ERISA liability for denied benefits. California's ABC test (codified in AB 5) is stricter than federal standards and has produced major employer liabilities in the gig economy. As a contractor, protect yourself by using written contracts specifying deliverables and milestones (not hours worked), maintaining multiple client relationships, invoicing properly through your own business entity, and keeping business records separate from personal finances. If you believe you've been misclassified by an employer, you can file IRS Form SS-8 to request an official determination — the IRS will investigate and reclassify with back-pay consequences for the employer.
