Federal law would limit states' power to tax multi-state workers

What it does

This bill restricts states' ability to tax employees who work across multiple states. Under the law, a multi-state worker's wages can only be taxed by their home state or by any state where they work more than 30 days in a calendar year. The bill exempts professional athletes, entertainers, production workers, and public figures from these protections, allowing states to continue taxing them. Employers gain safe harbor to rely on employees' self-reported work locations unless they have actual knowledge of fraud.

Why we flagged it

The bill's core mechanism is a federal constraint on state taxing power over multi-state workers. It is not a tax cut per se (no federal tax change), but a reallocation of taxing authority from states to home-state-only taxation, with narrow carve-outs for high-income performers.

What the text implies

• States with large commuter populations (e.g., border states, major metro areas) may experience significant revenue loss, potentially forcing tax increases on residents or service reductions.
• The 30-day threshold creates a bright-line rule that may incentivize employers to structure assignments to stay just under 30 days to minimize withholding obligations.
• Professional athletes, entertainers, and public figures are explicitly carved out, preserving states' ability to tax high-income performers—suggesting the bill's primary beneficiaries are ordinary multi-state workers, not celebrities.
• Employer reliance on employee self-reporting (absent fraud or collusion) shifts compliance risk and audit burden; employers have little incentive to verify accuracy if they face no penalty for honest reliance.
• The effective date is delayed to the second calendar year after enactment, giving states and employers time to adjust systems but also delaying revenue impact.

Who it affects

Multi-state workers gain tax simplification and potential lower tax burdens by limiting exposure to multiple state taxes, which is a concrete benefit. However, states lose revenue that funds public services (schools, infrastructure, emergency services), which may result in higher taxes elsewhere, service cuts, or reduced public investment—costs borne by all residents including those who benefit from the tax relief.

Who stands to gain

• Multi-state workers (reduced tax exposure)
• Employers with multi-state workforces (simplified withholding and compliance)
