The True Cost of Being 1099: What Nobody Tells You
A $120,000 contract sounds like a raise. After taxes, insurance, and the costs nobody mentions upfront, it often is not.
Every year, thousands of people accept contractor roles expecting more freedom and more money - and end up with less of both, at least financially. Not because contracting is bad. Because nobody sat them down and walked through the actual math before they signed. This article does that.
The Self-Employment Tax Surprise
This is the one that catches people most off guard. When you are a W2 employee, you pay 7.65% in FICA taxes (Social Security and Medicare). Your employer matches that 7.65% - you never see it, but it is real money being spent on your behalf.
As a 1099 contractor, you are your own employer. You pay the full 15.3% - technically calculated on 92.35% of your net earnings, but effectively about 14.1% of your gross contract income. On a $120,000 contract, that is roughly $16,900 in self-employment tax alone - on top of your regular income tax.
You do get one break: you can deduct half of the self-employment tax from your taxable income. But the other half is simply gone, a cost of running your own business.
Health Insurance: The Biggest Line Item
If your previous employer covered 70% of your health insurance premium, you may have paid $150-$200 per month. As a self-employed contractor, you now pay the entire premium - often $400-$700 per month for an individual plan on the marketplace, and $1,200-$2,000 per month for a family.
The good news: self-employed health insurance premiums are 100% deductible as an above-the-line adjustment to income. This means you can deduct the full premium without itemizing, which significantly reduces both your income tax and, indirectly, your self-employment tax base.
Even with the deduction, the out-of-pocket cost is typically $4,000-$8,000 per year more than what you paid as an employee. That gap needs to be covered by your higher contractor rate.
The Quarterly Tax Obligation
As a W2 employee, taxes are withheld from every paycheck automatically. You never have to think about it. As a 1099 contractor, nothing is withheld. Every dollar hits your bank account gross, and it is entirely your responsibility to set aside what you owe.
The IRS requires quarterly estimated tax payments - due in April, June, September, and January. If you underpay significantly, you face a penalty even if you pay the full amount by April 15. Most contractors should set aside 25-35% of every payment they receive, depending on their state and income level.
The practical consequence: your $10,000 invoice feels like $10,000 when it hits your account, but $2,500-$3,500 of it needs to go directly into a separate savings account. Contractors who skip this step find themselves scrambling for cash in April.

Benefits You Stop Receiving
401(k) Match
A 4% employer match on a $100,000 salary is $4,000 per year of free money. It does not show up on your paycheck, but it builds your retirement account automatically. As a contractor, that disappears. You can and should replace it with a Solo 401(k) or SEP-IRA - but the contribution comes entirely from your own income.
Paid Time Off
Contractors often think of PTO as a perk, not compensation. It is very much compensation. Two weeks of paid leave on a $90,000 salary is $3,460 of income you receive without working. As a contractor, you either work or you do not get paid. That time off now comes directly out of your annual billable income.
Other Protections
Employer-paid life insurance, short and long-term disability, workers compensation, and unemployment insurance all disappear. These are not glamorous, but disability insurance in particular can replace a meaningful chunk of income if you are unable to work. Replacing it privately costs money and is often skipped entirely by contractors who do not price it in.
The Hidden Time Costs
Contracting is running a small business. That means invoicing, chasing payments, managing quarterly taxes, maintaining business records, and handling your own accounting or paying someone to do it. A basic bookkeeper or CPA for a self-employed person runs $500-$2,000 per year. Tax software with Schedule C support costs more than standard W2 filing tools.
None of these costs are dealbreakers. But they need to be counted.
What Contracting Actually Costs: A Summary
On a $120,000 gross 1099 contract versus a $100,000 W2 salary (single filer, Texas, standard benefits):
| Cost | Approximate Annual Amount |
|---|---|
| Self-employment tax premium (vs W2 FICA) | $7,300 |
| Additional health insurance cost | $5,400 |
| Lost 401(k) employer match (3%) | $3,000 |
| Lost PTO value (15 days) | $4,615 |
| Accounting / bookkeeping | $1,000 |
| Total additional costs | $21,315 |
This means the $120,000 contract and the $100,000 salary are roughly equivalent in net take-home - confirming the 20% premium rule in this scenario.
The Upside You Should Not Ignore
None of this means 1099 is a bad deal. For the right person at the right rate, contracting is substantially better financially. The deductions are real. The retirement contribution limits are dramatically higher - up to $69,000 per year in a Solo 401(k) versus $23,500 in a standard workplace plan. And at high income levels, the ability to shelter more pre-tax income can more than offset the self-employment tax burden.
