W2 vs 1099 Calculator - Frequently Asked Questions

Clear, plain-language answers to the most common questions about contractor and employee pay.

What is the difference between W2 and 1099 income?
W2 income comes from being an employee: your employer withholds your income taxes, pays half of your Social Security and Medicare taxes, and typically provides benefits like health insurance, a 401(k) match, and paid time off. 1099 income comes from being an independent contractor or freelancer. You receive the full gross amount with nothing withheld, and you are responsible for paying all of your own taxes - including both halves of FICA - as well as buying your own benefits. The trade-off is that 1099 contractors can deduct business expenses and access higher-limit retirement accounts. Because of these differences, the same dollar figure means very different take-home pay depending on which classification it falls under.
Why do I pay more taxes as a 1099 contractor?
The main reason is self-employment tax. As a W2 employee you pay 7.65% in FICA taxes and your employer pays a matching 7.65%. As a 1099 contractor you are both the employer and the employee, so you pay the full 15.3% yourself. On a $100,000 income that employer portion alone is roughly $7,000-$7,650 of additional tax you now owe. You also lose pre-tax benefits that an employer would have provided. The good news is that you can deduct half of your self-employment tax and write off legitimate business expenses, which softens the blow - but contractors should still expect a higher overall tax burden than an equivalent W2 salary.
What is self-employment tax and how is it calculated?
Self-employment tax funds Social Security and Medicare for people who work for themselves. It is 15.3% total: 12.4% for Social Security (up to the annual wage base of $176,100 in 2025) and 2.9% for Medicare (with no cap). It is calculated on 92.35% of your net self-employment earnings, not the full amount. For example, on $80,000 of net earnings you would multiply by 0.9235 to get about $73,880, then apply 15.3% for roughly $11,300 in self-employment tax. You can deduct half of that amount (the 'employer-equivalent' portion) when calculating your federal income tax, which reduces your overall liability.
How much more should I charge as a 1099 contractor compared to my W2 salary?
A common rule of thumb is that a 1099 rate should be 25-30% higher than an equivalent W2 salary just to break even on take-home pay. So a $100,000 salary roughly corresponds to a $125,000-$130,000 contract, or about $60-$65 per hour at 2,000 billable hours per year. The exact figure depends on your state income tax, filing status, the benefits you are giving up, and the business expenses you can deduct. Our break-even calculator works backward from a specific W2 offer to tell you the precise hourly and annual rate you would need to match it, which is far more accurate than relying on a generic percentage.
Can I deduct health insurance as a 1099 contractor?
Yes. Self-employed individuals can deduct 100% of their health insurance premiums - including medical, dental, and qualifying long-term care - for themselves, their spouse, and dependents. This is an above-the-line deduction, meaning it reduces your adjusted gross income directly and you do not need to itemize to claim it. The deduction cannot exceed your net self-employment income, and you are not eligible for any month you were able to participate in a subsidized plan through a spouse's employer. This deduction is one of the most valuable tax advantages of contracting, since W2 employees generally cannot deduct their share of premiums the same way.
What is the best retirement account for self-employed people?
The two most popular options are the SEP-IRA and the Solo 401(k). A SEP-IRA lets you contribute up to 25% of your net self-employment income, capped at $69,000 in 2025, and is extremely simple to set up. A Solo 401(k) is often better for higher savers because it combines an employee contribution (up to $23,500 in 2025) with an employer profit-sharing contribution of up to 25% of net earnings, also capped at $69,000 total. The Solo 401(k) usually allows a larger contribution at moderate income levels and supports Roth contributions and loans. A SIMPLE IRA is a lower-limit option better suited to smaller businesses with employees.
How do quarterly estimated taxes work and when are they due?
Because no taxes are withheld from 1099 income, the IRS requires you to pay estimated taxes four times per year rather than waiting until April. You estimate your total annual tax liability - income tax plus self-employment tax - and pay roughly one quarter each period. For the 2025 tax year the due dates are April 15, 2025 (Q1), June 16, 2025 (Q2), September 15, 2025 (Q3), and January 15, 2026 (Q4). If you expect to owe $1,000 or more and underpay, you can face an IRS underpayment penalty. A simple strategy is to set aside a fixed percentage of every invoice in a separate savings account so the money is ready when payments are due.
Is it better to be W2 or 1099?
It depends on your priorities and the specific numbers. W2 employment offers stability, withheld taxes, employer-paid FICA, and benefits that add real value without effort. 1099 contracting offers higher gross pay potential, flexibility, business deductions, and access to large retirement contributions, but you take on all the tax and benefit responsibilities yourself. Financially, a contract usually needs to pay 25-30% more than a salary to break even. Beyond the math, consider job security, your tolerance for handling taxes and bookkeeping, and how much you value flexibility. Run both scenarios through the calculator and weigh the dollar difference against these non-financial factors.
How do I calculate the value of my W2 benefits package?
Add up the annual employer contribution to each benefit. Start with the portion of your health insurance premium the employer pays, then add the dollar value of the 401(k) match (your match percentage times your salary), any HSA contribution, the value of dental and vision coverage, and the dollar value of your paid time off (your daily rate times your PTO days). Include extras like life insurance, disability coverage, commuter benefits, and equity. A solid package commonly adds 20-30% on top of base salary. Our Benefits Value Calculator does this automatically and shows a breakdown pie chart so you can see exactly how much your benefits are worth.
What business expenses can I deduct as a 1099 contractor?
You can deduct ordinary and necessary expenses for running your business. Common ones include a home office (either actual expenses or the simplified $5 per square foot method), equipment and computers, business internet and a portion of your phone bill, software and subscriptions, professional development and training, business travel, and vehicle or mileage costs (70 cents per mile in 2025). You can also deduct health insurance premiums and retirement contributions. Keep careful records and receipts, and remember that expenses must be genuinely business-related. These deductions reduce both your income tax and, for most expenses, your self-employment tax, making them one of the biggest advantages of contracting.
