1099 vs W-2: How to Compare Contract and Salaried Income Accurately

Recruiters often quote contract rates and salaried offers in the same breath — but a $120,000 1099 contract is worth significantly less than a $120,000 W-2 salary after you account for every cost the employer normally absorbs.

This is one of the most common and costly miscalculations in modern hiring negotiations. Getting it wrong means accepting a pay cut while believing you negotiated a raise.

The self-employment tax: the hidden 15.3%

W-2 employees pay 7.65% for FICA (Social Security and Medicare). Their employer matches that 7.65% and remits it to the IRS invisibly — the employee never sees the employer share.

A self-employed 1099 contractor pays both sides. The self-employment tax rate is 15.3% on net self-employment income up to the Social Security wage base ($176,100 in 2026) and 2.9% on income above that. On $120,000 of net contract income, the SE tax bill is approximately $16,956 — before a single dollar of federal or state income tax is applied.

The IRS does allow a deduction for half of SE tax (roughly $8,478 in this example), which reduces adjusted gross income. But you still net out significantly worse on FICA than your salaried counterpart.

Benefits: the costs you now pay yourself

Employers typically cover a substantial portion of employee benefits. Bureau of Labor Statistics data puts the average employer benefit cost at approximately 29–32% of total compensation for private-sector workers. That includes:

Health insurance: Employers cover roughly 73% of employee-only premiums (KFF 2024 survey average: $1,369/month total premium, employer pays $1,003). A contractor buying the equivalent ACA plan individually might pay the full $1,369 — or more for a family plan.

Retirement matching: A common 401k match of 3–4% of salary represents $3,600–$4,800 in annual employer contributions on a $120,000 salary. A contractor funds their solo 401k or SEP-IRA entirely from their own income.

Paid time off: A two-week vacation for a W-2 employee costs the employer money. A 1099 contractor who doesn't work doesn't get paid. If you take 10 days off, you lose approximately $4,600 of billing time on a $120,000 annual run rate.

Other costs: Liability insurance, professional tools, software, and home office expenses are often employer-provided for W-2 workers; entirely contractor-funded for 1099s.

The real comparability formula

To compare a 1099 rate fairly to a W-2 salary, most financial advisors use a multiplier of 1.25x to 1.4x to account for the gap:

Item	W-2 Employee	1099 Contractor
Base pay	$120,000	$120,000
Employer FICA	+$9,180 (employer pays)	−$16,956 (you pay both sides)
Health insurance	+$12,036 (employer covers 73%)	−$16,428 (full premium)
401k match (4%)	+$4,800	$0
PTO (10 days)	+$4,615	$0
Other benefits	+$2,400	$0
True total value	~$153,031	$120,000 gross

So if a recruiter offers you a $120,000 1099 rate to match your current $120,000 W-2 compensation, you are looking at a real pay cut of roughly $33,000 before even calculating the difference in quarterly tax obligations.

What 1099 workers can deduct

The gap is partially offset by the ability to deduct legitimate business expenses on Schedule C:

• Home office: simplified method $5/sq ft up to 300 sq ft = $1,500 max
• Health insurance premiums: 100% deductible above-the-line for self-employed
• Retirement contributions: up to $70,000 via solo 401k (employee + employer contributions in 2026)
• Business travel, software, professional development: deductible at the business-use percentage
• Half of SE tax: deductible from AGI

The health insurance deduction is particularly valuable: self-employed individuals deduct 100% of premiums for themselves and their family from AGI, regardless of whether they itemize.

The Self-Employed Tax Calculator calculates exactly what you owe in SE tax, income tax, and estimated quarterly payments based on your gross 1099 income — making it straightforward to compare offers and set aside the right amount each quarter.
