Will the ‘Millionaires Tax’ Hurt Seattle Sports? It’s Complicated

Why It Matters

The tax could shift talent to lower‑tax markets, weakening Seattle’s competitive position and forcing costly contract redesigns across its sports franchises.

Key Takeaways

• 9.9% tax on earnings over $1 M may deter free‑agent signings
• Seahawks GM warns tax could diminish Seattle’s recruiting advantage
• Study finds each 1‑point tax rise cuts team win % by 0.7
• Teams likely to use bonuses, deferred pay to offset new tax burden

Pulse Analysis

The Washington legislature’s “millionaires tax,” a 9.9 % surcharge on income exceeding $1 million slated for 2028, adds a new fiscal layer to a market that has long benefited from a zero‑state‑income‑tax environment. Seattle’s NFL, MLB and NBA franchises have leveraged that advantage to attract free agents who can keep more of their contracts than peers in New York, Los Angeles or Chicago. As Seahawks general manager John Schneider warned, the looming levy could erode the city’s recruiting edge, forcing players to weigh tax savings against lifestyle and competitive prospects.

The tax’s ripple effect will be felt most in leagues with hard salary caps, such as the NFL, where every dollar saved on taxes translates directly into cap space. Front offices are already brainstorming contract architectures that shift income into signing bonuses, deferred payments, or performance‑based incentives—structures that can be taxed in lower‑jurisdiction years or spread over time. In contrast, MLB’s lack of a cap gives owners more flexibility, but even baseball clubs may adopt creative deals to keep star contracts attractive. Sports lawyers predict a wave of renegotiations as teams seek to preserve net earnings for athletes.

Beyond Seattle, the tax underscores a broader strategic calculus for professional sports. Academic research from the University of Illinois at Chicago links higher state income taxes to a 0.7‑percentage‑point dip in team winning percentages per tax‑point, suggesting a measurable competitive penalty. Markets like Texas, home to the Spurs, have thrived without an income tax, while high‑tax cities such as Los Angeles continue to win championships by leveraging other amenities. If Washington’s levy proceeds, we may see a gradual talent migration toward lower‑tax hubs, reshaping free‑agency dynamics across the major leagues.
