A client offers you a contract role at $90,000 a year. Another company offers a salaried W-2 position at $75,000. On paper, the contractor role pays $15,000 more. After running the actual numbers - self-employment tax, health insurance, retirement matching, and paid time off - the gap closes fast, and in some scenarios it reverses entirely.
This comparison is one of the most consequential financial calculations a freelancer or contractor faces, and most people do it wrong. They compare gross compensation figures instead of after-tax, after-benefits take-home amounts. This guide walks through the full calculation so you can make an informed decision rather than one based on headline numbers.

Why 1099 and W-2 Income Are Not Comparable at Face Value
The difference between 1099 and W-2 income is not just a paperwork distinction. It changes your total tax burden in a fundamental way.
When you earn income as a W-2 employee, your employer covers half of your Social Security and Medicare taxes. The combined FICA rate is 15.3% of wages. You pay 7.65% and your employer pays 7.65% on your behalf. That employer contribution does not appear on your paycheck - it is invisible to most employees - but it is real money your employer is spending to compensate you.
As a 1099 contractor, you pay both halves. That full 15.3% is your self-employment tax, applied to 92.35% of your net self-employment income. On $90,000 of net contractor income, self-employment tax runs to roughly $12,700. A W-2 employee earning $90,000 owes only the employee's 7.65% share, which is $6,885. The contractor's federal tax bill starts $5,815 higher before any income tax is even calculated.
The IRS self-employment tax overview explains the mechanic in full. The short version: the moment you go from W-2 to 1099, you absorb a tax cost that your employer was previously paying on your behalf.
Benefits Are a Second Major Adjustment
Beyond the SE tax difference, contractors must fund benefits that employers typically provide:
Health insurance: Employer-sponsored family plans often carry employer contributions of $800 to $1,400 per month. Individual marketplace plans for comparable coverage run similarly. If you are leaving a job where your employer covered most of that premium, you are now paying it in full. That is $9,600 to $16,800 per year that needs to factor into your comparison.
Retirement matching: Many W-2 employers match 401(k) contributions up to 3-6% of salary. On a $75,000 salary with 4% matching, that is $3,000 per year in employer contributions. Contractors can still build retirement savings - and can contribute more to a Solo 401(k) in some income ranges - but there is no matching component unless you provide it yourself.
Paid time off: A W-2 employee who takes two weeks of vacation is still paid. A contractor who does not work for two weeks earns nothing. If your annual rate assumes 52 working weeks but you realistically take two weeks off and have another two weeks of slow pipeline, your effective annual income is four weeks lower than your stated rate.
According to SHRM's compensation research, benefits commonly add 25 to 40 percent to total employment cost. That gap does not disappear when you become a contractor - it shifts from employer to you.
Step-by-Step: Running the Real Comparison
Step 1: Establish Net Contractor Income
Start with your gross contractor rate and subtract legitimate business expenses. Software, equipment, home office costs, professional development, and business insurance are all deductible. If your gross contract is $90,000 and you have $6,000 in business expenses, your net self-employment income is $84,000.
Step 2: Calculate Your Self-Employment Tax
Multiply net income by 0.9235, then by 0.153.
$84,000 x 0.9235 = $77,574
$77,574 x 0.153 = $11,869 in SE tax
You can deduct half of that ($5,935) from your gross income when calculating income tax. Adjusted gross income: $84,000 - $5,935 = $78,065.
Step 3: Estimate Federal Income Tax
Apply the 2026 brackets to your AGI after the standard deduction ($15,000 for single filers). Taxable income: $78,065 - $15,000 = $63,065. Federal income tax on that figure is approximately $9,500.
Total federal tax: $11,869 + $9,500 = $21,369.
Step 4: Add Back Benefit Costs
If you are paying $800 per month for health insurance as a contractor: add $9,600.
If you are forgoing 3% employer retirement matching on a $75,000 equivalent: add $2,250.
Two weeks of unpaid time on a $90,000 gross rate: subtract approximately $3,461 from annual earnings.
Adjusted contractor cost: $21,369 (taxes) + $9,600 (health) + $2,250 (foregone retirement) = $33,219 in combined tax and benefit costs. Effective net income on $90,000 gross: $90,000 - $3,461 (unpaid time) - $33,219 = $53,320.
Step 5: Run the W-2 Comparison
For a $75,000 W-2 salary with employer health coverage and 3% retirement matching:
- Employee FICA (7.65%): $5,738
- Federal income tax on $60,000 taxable income: approximately $8,100
- Employee health premium ($200/month): $2,400
Net W-2 take-home: $75,000 - $5,738 - $8,100 - $2,400 = $58,762.
In this scenario, the $75,000 W-2 position produces more net income than the $90,000 contract. The contractor would need approximately $97,000 to $100,000 in gross revenue to match the W-2 after-tax, after-benefit equivalency. That is the breakeven rate - the minimum contractor compensation that makes the 1099 path financially equivalent.
The 1099 vs W-2 Calculator on EvvyTools runs this full comparison for you. Enter your contractor rate and the W-2 offer side by side along with your state, estimated expenses, and benefit costs. The tool shows after-tax take-home for both scenarios and calculates the exact breakeven contractor rate for your specific numbers.

Common Mistakes That Skew the Comparison
Comparing gross numbers only: This is the most common error. A $90K contract versus a $75K salary is not a $15K advantage for the contractor. It might not be any advantage at all, depending on your tax situation and benefit costs.
Ignoring quarterly estimated taxes: W-2 workers have taxes withheld automatically. As a contractor, you owe quarterly estimated payments four times a year, and if you underpay, you face IRS penalties on top of what you owe. Budgeting for those payments - and understanding how to calculate them safely - is part of the total cost of being self-employed. For a full breakdown of the quarterly tax calculation and safe harbor rules, How to Calculate Your Quarterly Estimated Taxes covers the complete process.
Not accounting for state income tax differences: Some states have no income tax. Others have rates above 9%. If you are comparing offers across state lines - or if one role allows remote work from a lower-tax state - that difference needs to be in the calculation.
Skipping the retirement contribution gap: Many W-2 employees underestimate how much employer retirement matching contributes to their total compensation. If you are walking away from $3,000 to $4,000 per year in matching contributions, that needs to be factored into the minimum contractor rate you would accept.
