Multiple states are revisiting or advancing surcharges on million-dollar incomes. For HR leaders, the after-tax value of executive and high-earner compensation is becoming more volatile and more jurisdiction-sensitive.
“Democratic legislators in Washington state approved a bill that will place a 9.9% tax on those who earn more than $1 million. That bill now heads to the state governor’s desk,” according to Marketplace, a public media outlet.
California, Massachusetts and New Jersey currently have “millionaire taxes.“ The report goes on to say that some states, such as California and Illinois, are now trying to “propose a one-time ‘billionaire tax’ on the unrealized gains of billionaires.”
When a state adds a millionaire surcharge, moving an employee from $950,000 to $1.1 million in total compensation, for example, can trigger a steep implicit tax jump. Compensation committees and HR leaders may need to revisit long-term incentives, employer-sponsored retirement vehicles and deferred-compensation structures that can smooth the tax impact over time.
‘Millionaire tax’ and HR responsibilities
Payroll teams are on the front line. With 2026’s updated withholding tables and evolving rules around SECURE 2.0 catch-up provisions for high-earner 401(k) plans, systems must accurately reflect new brackets, caps and bonus-trigger thresholds, according to a brief published by Thompson Reuters. HR information system partners should confirm that payroll vendors or in-house platforms can flag employees who cross high-income thresholds.
Research and expert commentary suggest that increases in tax rates can push high-earning professionals to consider relocating, negotiating more equity compensation or accelerating liquidity events such as stock-option exercises. That makes office-location decisions, remote-work policies and relocation support budgets part of a tax-sensitive talent strategy, not just a real estate or cost-of-living calculation.
Many senior executives and high-earning specialists may follow tax issues closely, but still benefit from employer-sponsored guidance on how surcharges, bracket changes or equity-trigger events affect their take-home pay. HR-led workshops or one-on-one sessions with tax specialists can help sustain perceived total-rewards value, even as headline tax rates rise.
