Minnesota Should Learn From Europe: Wealth Taxes Are a Failed Experiment

Why It Matters

The tax threatens to widen Minnesota’s fiscal deficit while potentially driving high‑net‑worth individuals and capital out of the state, undermining long‑term growth. It also highlights the broader risk that wealth taxes, despite political appeal, often fail to deliver promised revenues and can distort investment.

Key Takeaways

• Minnesota's bill taxes wealth over $10 million at 1 % starting 2026
• Projected revenue $290 million, far short of $2.7 billion budget gap
• European wealth taxes repeatedly failed, prompting repeals across OECD
• Simulations show a 1‑2 % tax could cut US GDP by ~5 %
• Valuing illiquid assets each year creates high compliance costs and asset sales

Pulse Analysis

The Minnesota House has moved HF 4616, a pioneering state‑level wealth tax that would levy a 1 % charge on personal and trust assets exceeding $10 million, beginning in tax year 2026. The proposal estimates $290 million in annual revenue from roughly 5,600 high‑net‑worth filers, a modest contribution against a projected $2.7 billion shortfall for FY 2026‑27 that widens to $3.36 billion by 2028‑29. While the measure mirrors a wave of wealth‑tax ideas in California, New York and Illinois, Minnesota’s lower threshold makes it the most aggressive of the group.

Economists warn that wealth taxes are uniquely distortionary because they tax a stock of capital rather than a flow of income. Simulation studies suggest a 1‑2 % levy could shrink the U.S. capital stock by 13 % and depress GDP by nearly 5 %, while European experience shows capital flight—France’s former wealth tax coincided with roughly €200 billion (about $218 billion) of asset outflows. Compliance adds another layer of cost: annual valuations of private businesses, farms or art require costly appraisals, forcing cash‑poor owners to sell productive assets to meet tax bills.

Given the modest revenue upside and the risk of driving entrepreneurs and investors out of Minnesota, policymakers would be wiser to pursue broader tax reforms that improve competitiveness rather than adding a complex wealth levy. States with simpler, growth‑oriented tax structures have consistently attracted inbound migration, as IRS data on inter‑state moves demonstrate. By focusing on expanding the tax base, modernizing administration, and reducing rates on income and consumption, Minnesota could close its budget gap without sacrificing long‑term economic vitality.
