1099 vs W2: How to Run the Numbers Before You Switch

The hidden tax most people miss

When a company offers you $75/hr as a W2 employee, they’re paying half your Social Security and Medicare taxes on top of that. You see 7.65% leave your paycheck as FICA, and they quietly send another 7.65% to the IRS on your behalf.

When that same company offers you $75/hr as a 1099 contractor, both halves are yours to pay. That’s 15.3% in self-employment tax before a single dollar of income tax is calculated. On $75/hr at 40 hours a week, that’s roughly $11,700 in additional taxes per year compared to W2 — money that disappears before federal and state income tax even enters the picture.

This is the calculation most people skip. They see a higher hourly rate, assume it means more money, and say yes. Then April comes.

Self-employment tax explained

Self-employment tax is the IRS’s way of collecting both the employee and employer portions of FICA from people who work for themselves. As a W2 employee, your employer pays 7.65% and you pay 7.65% — 15.3% total, but only half comes out of your paycheck. As a 1099 contractor, you pay the full 15.3%.

There’s a partial offset: the IRS lets you deduct 50% of your self-employment tax from your gross income before calculating federal income tax. This reduces your adjusted gross income slightly, but it doesn’t change the fact that the cash leaves your account.

For 2026, the Social Security portion of SE tax applies to the first $184,500 of net self-employment income. Above that threshold, only Medicare (2.9%) applies. High earners above $200,000 also face an additional 0.9% Medicare surtax.

How to run the numbers side by side

The only fair comparison is after-tax take-home, not gross rate. Here’s what a $75/hr 1099 offer looks like against a $60/hr W2 offer at 40 hours per week, 50 weeks a year, in a state with a 5% income tax:

On raw take-home, the 1099 offer wins by about $8,400. But once you subtract the cost of individual health insurance and account for the W2 employer’s 401(k) match and PTO, the gap narrows dramatically — and often reverses entirely.

The benefits gap: what W2 is really worth

Gross salary comparisons are misleading because W2 compensation is never just salary. Employers routinely provide benefits worth $10,000–$25,000 per year that don’t appear on a pay stub. When you switch to 1099, those costs become yours.

Health insurance

The average employer contribution to employee health insurance is over $7,000 per year for single coverage and over $20,000 for family coverage, according to the KFF 2024 Employer Health Benefits Survey. As a 1099 contractor, you pay the full premium yourself. Individual marketplace plans for a healthy 35-year-old typically run $400–$700/month — roughly $4,800–$8,400/year before any claims.

Retirement match

A 3% employer 401(k) match on a $120,000 salary is $3,600/year going into your retirement account at no cost to you. As a contractor, that $3,600 is simply gone. You can still contribute to a SEP-IRA or Solo 401(k) — and the contribution limits are actually higher — but the employer contribution is not replicated.

Paid time off

Two weeks of PTO on a $120,000 salary is worth $4,615. As a 1099 contractor, every day you don’t work is a day you don’t get paid. Factor in sick days, holidays, and vacation, and this adds up to 3–5% of annual gross income that W2 employees receive and contractors don’t.

Finding your 1099 break-even rate

The break-even 1099 rate is the hourly rate at which your after-tax, after-benefits take-home equals what you’d net from the W2 position. The standard rule of thumb is to add 25–35% to the W2 equivalent rate — but the actual number depends on your specific tax situation, health insurance costs, and how much your employer was contributing.

Here’s a simple framework. Start with your W2 annual salary and work forward:

That’s before accounting for income volatility, unpaid gap time between contracts, and the administrative cost of running your own business. Most experienced contractors add another 10–15% buffer on top of the pure break-even rate.

What 1099 workers can deduct

The tax picture for 1099 contractors isn’t entirely worse than W2. Independent contractors can deduct legitimate business expenses directly from gross income before calculating taxable income — deductions that W2 employees generally cannot take.

Health insurance premiums are worth calling out specifically: as a self-employed person, you can deduct 100% of what you pay for health insurance directly from your adjusted gross income — reducing both federal and state taxable income. At a $500/month premium and a combined 28% tax rate, that deduction saves roughly $1,680/year.

For high-earning contractors, the SEP-IRA contribution limit is substantial: up to 25% of net self-employment income, capped at $70,000 for 2026. This dramatically exceeds the W2 employee 401(k) limit of $23,500 and can meaningfully reduce your tax bill at higher income levels.

Quarterly taxes: the cash flow reality

As a W2 employee, taxes are withheld from every paycheck automatically. You never see the money — it goes to the IRS before it reaches your account. As a 1099 contractor, you receive your full invoiced amount and are responsible for setting aside and paying taxes yourself, four times a year.

The 2026 estimated tax deadlines are:

The IRS penalizes underpayment even if you pay the full amount by April 15. Timing matters. The most reliable system: open a separate savings account and transfer 28–35% of every client payment immediately. The exact percentage depends on your combined federal, state, and SE tax rate — use the 1099 vs W2 calculator to estimate your effective rate, then add a 3–5% buffer for safety.

How to actually make the decision

The math matters, but it’s not the whole picture. Here’s a framework for thinking through the decision beyond the numbers.

The 1099 arrangement makes financial sense when:

The rate premium covers your full benefits gap and SE tax delta — typically 30%+ above the equivalent W2 rate. You have a stable pipeline of work that reduces income volatility. You have legitimate business expenses that will meaningfully reduce your taxable income. You’re in a high tax bracket where the SEP-IRA’s larger contribution limit creates significant tax shelter. You can secure affordable individual health insurance (especially important if you’re healthy and young).

The W2 arrangement is likely better when:

The rate premium is under 20% — not enough to cover SE tax plus benefits. You have dependents on your health plan and individual coverage would be significantly more expensive. You value income predictability and the role has room to grow in compensation. The employer’s 401(k) match and benefit package is generous relative to the industry. You’re early in your career and the role provides mentorship, training, or credentials that have long-term value beyond the paycheck.

The number that actually matters

After all the analysis, reduce the decision to one figure: your after-tax, after-benefits monthly take-home under each scenario. That’s what pays your rent. Everything else is context. Use the calculator, enter conservative numbers on the 1099 side, and if the gap still favors the contract — take it.
