If you run a business with employees in California, the word "wages" just got a lot bigger — and so did your compliance exposure.
Starting January 1, 2026, California's SB 642 (the Pay Equity Enforcement Act) rewrites how the state's Equal Pay Act defines compensation. For years, "wages" in equal-pay disputes meant something close to base salary or hourly rate. SB 642 blows that definition open: it now covers bonuses, stock and stock options, gas and cleaning allowances, hotel accommodations, travel reimbursements, and effectively any form of pay an employer provides. If you thought equal-pay compliance was about matching base salaries across similarly situated employees, you now have to think about the entire compensation package — every perk, every allowance, every equity grant.
For small and mid-sized employers who've never had to run a formal pay-equity audit, this is the year that changes. Here's what actually shifted, why it matters even if you have no intention of discriminating on pay, and how to get your records in shape before a complaint — not after one.
What SB 642 Actually Changes
SB 642 amends California Labor Code Section 1197.5, the state's Equal Pay Act, in three concrete ways.
1. "Wages" Now Means Total Compensation
Before SB 642, the Equal Pay Act didn't formally define "wages" or "wage rates" at all — courts and regulators mostly read it as base pay. The new law spells it out explicitly: wages include "all forms of pay, including, inter alia, bonuses, stock, stock options, cleaning or gasoline allowances, hotel accommodations, and reimbursement for travel expenses."
That "inter alia" (Latin for "among other things") is doing a lot of work. It signals the list isn't exhaustive — regulators and plaintiffs' attorneys will read it as an invitation to argue that any employer-provided benefit with monetary value counts. Health insurance subsidies, remote-work stipends, signing bonuses, relocation packages — all now plausibly fall inside the definition.
What this means practically: if you pay two employees in the same role the same base salary, but one gets a company car allowance and the other doesn't, you may now have an equal-pay exposure you didn't have in 2025.
2. Gender Language Broadened
SB 642 replaces "opposite sex" with "another sex" throughout the Equal Pay Act's comparison language, aligning it with how the law already treats race- and ethnicity-based pay comparisons. This isn't a symbolic change — it clarifies that pay-equity comparisons apply across the full spectrum of gender identity, not just binary male/female pairs, closing a gap that had made some claims harder to bring.
3. Every Paycheck Can Restart the Clock
SB 642 also codifies what counts as a separate violation: adopting a discriminatory compensation practice, being subjected to one, or — critically — receiving each individual paycheck issued under it. Under the amended law, the statute of limitations for filing a claim runs three years from the most recent discriminatory paycheck, and back pay can be recovered for the full violation period, capped at six years.
In practice, this means a pay disparity that started in 2022 doesn't age out of enforceability just because it's now 2026 — as long as the underpaid employee is still receiving those paychecks, the clock keeps resetting.
What Didn't Change (and Where Confusion Creeps In)
SB 642 is easy to conflate with two other things it's not:
- It doesn't change job-posting pay scale rules. California's separate pay-transparency law (Labor Code 432.3, requiring employers with 15+ employees to post pay ranges) is untouched by SB 642's wage-definition expansion. SB 642 does clarify that a posted "pay scale" means a good-faith estimate of what the employer expects to pay upon hire — not a range that accounts for years of tenure or future promotions. That's a narrower, separate clarification, not the headline change.
- It's not the same as SB 1162's pay data reporting requirement. California's annual pay data report to the Civil Rights Department (due each May) is a distinct filing obligation for employers with 100+ employees. SB 642 amends what counts as "wages" in a lawsuit or DFEH/CRD complaint — it doesn't touch the reporting form itself.
If you've already updated your job postings for pay-scale compliance, that's good — but it's a different checklist from what SB 642 requires.
Why This Hits Small Businesses Harder Than You'd Expect
Larger employers with dedicated HR and compensation teams already track total rewards — base pay, bonus targets, equity vesting schedules, benefits value — in a unified system, often because they need it for financial reporting or investor disclosures anyway. Small businesses frequently don't. It's common to see:
- Base pay tracked in a payroll system
- Bonuses decided informally and paid as one-off checks
- A gas card or phone stipend handled as a reimbursement, outside of payroll entirely
- Equity grants tracked in a cap table tool that never talks to payroll
Under the old, narrower reading of "wages," that fragmentation was a bookkeeping inconvenience. Under SB 642, it's a compliance blind spot: if a regulator or plaintiff's attorney asks you to demonstrate that two employees in comparable roles received equitable total compensation, you need to be able to produce that total — reliably, for every employee, going back years — not reconstruct it after the fact from scattered receipts and Venmo notes.
A Practical Compliance Checklist
You don't need a general counsel on retainer to get ahead of this. Here's a reasonable starting point for a business with California employees:
1. Inventory every form of compensation you actually pay
Go role by role and list everything of monetary value each employee receives: base salary or hourly wage, overtime, bonuses (spot and structured), commissions, equity or options, allowances (gas, phone, home office, wellness), reimbursed travel and lodging, and any other perk with a dollar value attached.
2. Consolidate the record
Whatever your bookkeeping system, make sure every one of those compensation types is recorded against the employee it was paid to — not buried in a generic "office expenses" or "travel" category that doesn't tie back to a person. If your books can't answer "what was this employee's total compensation in 2025, broken out by type?" in a few minutes, that's the gap to close first.
3. Run an internal comparison by role
For employees performing substantially similar work (California's Equal Pay Act standard, not just identical job titles), compare total compensation, not just base pay. Document your reasoning for any differences — seniority, merit, quantity/quality of production, and legitimate business factors other than sex, race, or ethnicity are the recognized defenses under the statute. Write the reasoning down now, while it's fresh and defensible, not two years from now when a claim arrives.
4. Fix retention practices
California already requires employers to keep records of job titles and wage rate history for current employees, and for three years after employment ends. SB 642's expanded wage definition means those retained records need to capture total compensation, not just base pay stubs.
5. Revisit non-cash benefits with real dollar value
Company vehicles, hotel stays for work travel, cleaning allowances for field workers, gas cards for delivery staff — these are called out by name in the statute's list. If any of these differ between similarly situated employees, be ready to explain why in terms the law recognizes.
The Bookkeeping Root of the Problem
Almost every compliance headache in this story traces back to the same root cause: compensation data that lives in too many disconnected places. A bonus paid via a one-off check that never got coded consistently. A travel reimbursement logged as a general business expense instead of tagged to the employee and the pay period. An equity grant tracked in a spreadsheet nobody reconciles against payroll.
This is exactly the kind of problem that plain-text, version-controlled accounting is built to solve. When your books are structured data — not scattered PDFs and disconnected spreadsheets — every dollar of compensation can be tagged with the employee, the pay period, and the compensation type, and queried instantly. "Show me total 2025 compensation, by type, for every employee in the Sales department" becomes a query you can run in seconds rather than a multi-week reconstruction project the week a demand letter arrives.
Keep Your Compensation Records Audit-Ready
Pay equity laws like SB 642 reward businesses that can produce clear, complete compensation records on demand — and penalize the ones that can't. Beancount.io gives you plain-text accounting with full transparency and version history, so every bonus, allowance, and reimbursement is tagged, traceable, and ready to report on the moment you need it, whether that's for a pay-equity review or your own peace of mind.
