California (CA) 1099 vs W2 Calculator

California taxes both W2 wages and 1099 net profit using the same graduated brackets (1%–13.3%). On the 1099 side, the deductible half of SE tax reduces CA AGI slightly, giving a small CA state tax advantage to contractors at the same income level. However, the federal SE tax gap (15.3% vs 7.65% FICA) far outweighs this state benefit. At $100k gross in CA, a contractor pays roughly $14,000 more in combined taxes than a W2 employee at the same pay.

California SDI (State Disability Insurance, ~0.9% of wages) applies to W2 employees only — not to self-employed contractors. This slightly narrows the W2 advantage in CA, though SDI is not included in this calculator. If you factor in SDI, the effective W2 tax rate increases by about 0.9%, making the 1099 vs W2 comparison marginally closer in California.

As a W2 employee your employer pays half of Social Security and Medicare taxes on your behalf — about 7.65% of your wages. As a 1099 contractor you pay both halves yourself (15.3% on 92.35% of net profit). That payroll tax gap is the primary reason the same gross pay produces a smaller check as a contractor. Adding state income tax to both sides shows the true combined difference in your state.

California taxes ordinary income including both W2 wages and 1099 net profit using the same brackets. However, the 1099 side benefits from the deductible half of SE tax, which reduces federal AGI and therefore California taxable income in most cases. This slightly narrows — but does not close — the overall 1099 vs W2 gap.

In California, the break-even premium reflects both the federal payroll tax gap and the state income tax. Because state income tax applies to both sides, the break-even premium is driven primarily by the SE tax vs FICA difference, but the state tax affects both denominators. The calculator computes the precise break-even for the income level you enter.

The 20% Qualified Business Income (QBI) deduction is a federal deduction only — it reduces federal income tax on the 1099 side but does not affect California state income tax. In states with their own income tax, this means the QBI benefit narrows the federal income tax gap but leaves the state income tax gap unchanged. Most freelancers under the income threshold ($201,775 single / $403,550 MFJ for 2026) qualify for QBI.

This calculator shows the employee's share of taxes. Your W2 employer also pays an equal 7.65% in employer FICA (matching your Social Security and Medicare), plus state unemployment insurance (FUTA/SUTA), and potentially other payroll taxes. These employer costs are a real benefit to you as an employee — they're why companies often offer 1099 rates 20–30% higher than equivalent W2 salaries.
