Takeaway
Three Washington employment laws took effect in June 2026. While all three laws are effective as of June 11, key provisions phase in later — and each introduces new compliance expectations for HR and payroll teams. Read what you need to know about the new Washington employment laws.
When do the new Washington employment laws go into effect?
HB 2105, HB 2345 and HB 2479 all take effect on June 11, 2026.
However, each law includes different implementation timelines:
- HB 2105: Core compliance requirements begin Oct. 1, 2026.
- HB 2345: Payroll deduction changes apply Jan. 1, 2027.
- HB 2479: Wage recovery program begins no earlier than July 1, 2028.
This staggered timeline gives employers time to prepare, but also creates risk if changes are not carefully tracked across HR and payroll workflows.

HB 2105: What are the new rules for I-9 inspections in Washington?
What the law requires
HB 2105 requires employers to notify employees within five business days of a federal Form I-9 inspection notice and again within five business days after receiving inspection results.
The law also:
- establishes antiretaliation protections
- places limits on certain reverification practices
- introduces penalties for failure to comply
Who is affected
Any employer with employees in Washington who is subject to a federal I-9 inspection or audit.
Why this matters for HR and payroll
While I-9 compliance is typically managed by HR, employee data, audit logs and documentation frequently intersect with payroll systems and recordkeeping tools.
This creates operational risks such as:
- missed notification deadlines due to unclear ownership of compliance workflows
- inconsistent communication across departments or locations
- improper reverification activity triggered by outdated processes
How HB 2105 affects HR and payroll activity
To comply with HB 2105, organizations will need to introduce:
- trackable notification workflows (to meet five-day deadlines)
- centralized visibility into inspection activity
- documented processes for employee communication
How to prepare
- Assign a single owner responsible for inspection notices.
- Build standardized employee notification templates.
- Implement a tracking system for compliance deadlines.
- Train HR managers and supervisors on antiretaliation protections.
HB 2345: What do I need to know about PFML changes?
What the law does
HB 2345 changes how Washington Paid Family and Medical Leave (PFML) premiums are allocated between family leave and medical leave.
Importantly:
- It does not change total contribution levels.
- It does not change the employer vs. employee split overall.
Instead, it reallocates how contributions are divided within the program.
When it takes effect
- effective: June 11, 2026
- payroll impact: Jan. 1, 2027
How HB 2345 affects payroll
Although this change is administrative, it directly impacts how payroll deductions are calculated and applied.
Payroll teams will need to:
- apply updated deduction caps for employees
- adjust contribution calculations between leave categories
- ensure systems reflect new allocation rules when 2027 rates are released
Where errors are most likely
Common failure points include:
- miscalculating employee deductions under new caps
- applying outdated system configurations into 2027
- incorrectly allocating premium shares between leave categories
How to prepare
- Confirm payroll systems can support updated PFML logic.
- Monitor rate and implementation guidance from Washington agencies.
- Validate employer size classification annually (affects contribution obligations).
- Coordinate payroll updates with tax and compliance advisers.
HB 2479: What are the penalties for unpaid wages in Washington?
What the law changes
HB 2479 increases the minimum penalty for willful unpaid wage violations to $1,500 or 10% of unpaid wages (whichever is greater) and removes the previous penalty cap.
The law also:
- allows penalties up to the full amount of unpaid wages plus interest
- introduces penalties for repeat violations
- expands enforcement authority
Why this is the highest-risk change
HB 2479 significantly increases financial exposure because:
- A single complaint can trigger a broader investigation.
- Penalties are no longer capped.
- Repeat issues can amplify financial and legal risk.
How HB 2479 affects HR and payroll activity
This law places greater emphasis on payroll accuracy and audit-readiness.
Payroll risks now carry higher consequences, particularly for:
- variable pay structures
- manual adjustments
- multilocation or multistate payroll operations
Payroll scenarios with elevated risk
Under HB 2479, higher penalties may result from:
- incorrect overtime calculations
- late or inaccurate final pay
- off-the-clock work not captured in payroll systems
- errors in manual pay adjustments or corrections
- misclassification affecting wage calculations
How to prepare
- Audit wage and timekeeping practices across the organization.
- Review prior wage complaints and resolutions.
- Strengthen payroll controls and validation processes.
- Maintain detailed and accurate employee records.
