The push to raise taxes on top earners is expanding beyond large coastal economies, with Maine emerging as the latest state to pursue higher levies on high-income households. Maine Governor Janet Mills and Democratic lawmakers in Augusta are backing proposals to increase taxes on the state’s highest earners as part of ongoing budget discussions, reflecting a broader national shift in how states are approaching revenue generation.
At the center of the effort is a proposal from Maine House Speaker Rachel Talbot Ross and Senate President Troy Jackson, who have signaled support for increasing income tax rates on top brackets to fund education, healthcare, and infrastructure. Supporters argue the approach allows the state to raise needed revenue without broadly impacting middle- and lower-income residents, a key political consideration as cost-of-living pressures persist.
Opposition has quickly formed among business groups and Republican lawmakers, including Maine Senate Minority Leader Trey Stewart, who warned that increasing taxes on high earners could undermine the state’s competitiveness. “We have to be very careful about policies that could push entrepreneurs and investors out of Maine,” Stewart said in recent remarks, pointing to migration trends seen in higher-tax states.
Economists say the debate in Maine reflects a larger national pattern, but with unique risks for smaller markets. Jared Walczak, vice president of state projects at the Tax Foundation, noted that while progressive tax policies can generate short-term revenue, they may also introduce volatility. “States with a narrower base of high-income taxpayers are more exposed if even a small number of those taxpayers relocate,” Walczak said.
The trend is not isolated. States including New York and California have long relied on high earners for a significant share of tax revenue, but smaller states are increasingly considering similar approaches. Katherine Loughead, senior policy analyst at the Tax Foundation, said policymakers are under pressure to find targeted revenue sources. “There’s a growing inclination to look at high-income households as a way to close budget gaps without broad-based tax increases,” Loughead explained.
Supporters of the Maine proposal argue the economic context has shifted in their favor. Governor Janet Mills has emphasized the need for sustainable funding as federal pandemic-era support fades. “We must ensure Maine has the resources to invest in its people and its future,” Mills said in a recent budget statement, underscoring the administration’s focus on long-term fiscal stability.
At the same time, the mobility of high earners remains a key concern. Mark Zandi, chief economist at Moody’s Analytics, has noted that remote work has made relocation easier, particularly for high-income individuals. “Tax differentials matter more when people have flexibility in where they live and work,” Zandi said, adding that smaller states may feel the effects more acutely.
Business leaders warn that higher taxes could also affect investment decisions. David Clough, a Maine-based business advocate and former head of the Maine Development Foundation, said policies targeting top earners can have ripple effects. “Many high-income taxpayers are also business owners and investors, so changes to their tax burden can influence hiring, expansion, and capital allocation decisions,” Clough said.
Still, proponents maintain that the approach is both fair and necessary. Rachel Talbot Ross has argued that those with the greatest ability to pay should contribute more toward public needs. “We are focused on building an economy that works for all Mainers, and that requires responsible, equitable revenue policies,” Talbot Ross said in legislative discussions.
The outcome in Maine is being closely watched by policymakers across the country. Jared Walczak noted that smaller states adopting wealth-focused tax strategies could set important precedents. “If states like Maine can implement these policies without significant economic disruption, others may follow,” he said.
For businesses and investors, the evolving landscape highlights the growing importance of state-level tax policy. As Katherine Loughead observed, “Tax structure is increasingly a factor in where people choose to live, work, and invest,” a dynamic that could reshape economic competition among states.
As Maine moves forward, the debate underscores a broader shift in fiscal policy across the U.S.—one where even smaller states are weighing the benefits and risks of relying more heavily on their highest earners to fund future growth.
