California has the most complex payroll compliance requirements of any US state — 13 tax brackets, mandatory SDI and PFL contributions, EDD reporting obligations, and CalSavers auto-enrollment. Paylon handles all of it automatically so you can run payroll in minutes, not days.
California employers must withhold state income tax, SDI, and — when applicable — additional taxes for employees subject to local payroll taxes. Here's the complete picture for a California payroll run:
| Tax | Rate | Who Pays | Notes |
|---|---|---|---|
| CA State Income Tax | 1% – 13.3% | Employee | 10 progressive brackets; highest bracket kicks in at $1M+ |
| SDI (State Disability Insurance) | 1.1% (no wage cap) | Employee | Funds both SDI and PFL; unlimited wage base since 2024 |
| SUI / ETT (Employer) | 1.5% – 6.2% | Employer | New employer rate: 3.4% on first $7,000 per employee |
| Federal Income Tax | 10% – 37% | Employee | Standard federal brackets apply |
| Social Security | 6.2% (employer + employee) | Both | Wage base: $176,100 (2026) |
| Medicare | 1.45% + 0.9% surcharge | Both / Employee | Additional 0.9% on wages over $200K (single) |
Beyond tax withholding, California employers face a compliance checklist that changes every year. Miss any of these and you're looking at EDD notices, back-payment obligations, or civil penalties:
California's payroll rules are layered — each year the state adds or adjusts requirements. The 2024 change to SDI (removing the wage cap) alone required every California employer to recalculate withholding mid-year. Teams relying on manual spreadsheets or legacy software discovered the change when their payroll was already wrong.
The SDI program funds both short-term disability and paid family leave. When an employee files a PFL or SDI claim, the EDD looks at the employer's payroll records to verify contributions. Any withholding discrepancy can delay or reduce the employee's benefit — a compliance failure that directly harms your workers.
California's progressive income tax structure adds another layer. With 10 brackets ranging from 1% to 13.3%, every compensation change — a raise, a bonus, a one-time payment — requires recalculating withholding at the correct marginal rate. Supplemental wages like bonuses use a separate flat rate (10.23% for withholding purposes), which must be applied correctly or you'll either over- or under-withhold.
Paylon calculates California SDI at 1.1% on every dollar of wages — no wage cap to track, no manual rate updates when EDD changes rates annually. PFL eligibility is tracked automatically alongside SDI contributions.
Quarterly DE 9 and DE 9C filing data is generated automatically from your payroll runs. No manual data entry into EDD's portal — Paylon produces audit-ready records every pay period.
CA's 10 income tax brackets are applied precisely, including the correct withholding method for supplemental wages. When an employee crosses a bracket threshold mid-year, calculations update automatically.
California's statewide minimum wage is $16.50/hour as of January 2026. Fast food workers covered under AB 1228 are subject to $20/hour minimums. Healthcare workers at large facilities may have higher sector-specific minimums.
Some cities and counties have their own minimum wages that exceed the state floor: Los Angeles City ($17.28/hour), San Francisco ($18.67/hour), and others. Paylon tracks the correct minimum for each employee's work location and flags potential violations before they become Labor Board complaints.
California's Employment Development Department runs one of the most active payroll audit programs in the country. If your SDI withholding records don't match employee claims, expect a compliance inquiry. If your SUI contributions are understated, expect an assessment with interest and penalties.
Paylon maintains a complete, immutable audit trail for every California payroll run — every withholding calculation, every contribution rate applied, every filing-ready record — so that an EDD audit is a documentation exercise, not a fire drill.
