Bye-bye paycheck taxes? Mississippi and Kentucky plan to eliminate state income tax in decades

In a bold shift in fiscal policy, Mississippi and Kentucky have unveiled major tax reforms aimed at eliminating personal income taxes—an action unseen in the US since Alaska ended its income tax in 1980. These southern states are joining a national wave focused on tax relief and economic competitiveness.

Mississippi’s Roadmap to Zero Income Tax

Governor Tate Reeves of Mississippi recently signed legislation outlining a step-by-step plan to completely phase out the state’s 4% income tax by 2040. The plan begins with a reduction to 3% by 2030 and includes further conditional cuts based on revenue benchmarks.

Key changes under Mississippi’s plan:

  • Income tax phase-out: 4% reduced gradually to 0% by 2040
  • Grocery sales tax: Proposed reduction to support lower-income households
  • Gas tax: Proposed hike to offset revenue losses

Reeves stated, “This puts us in a rare class of elite, competitive states,” referencing income-tax-free states like Florida and Texas.

However, critics argue the risks are steep. Mississippi is one of the country’s poorest states and relies heavily on federal aid. Tax experts like Neva Butkus from the Institute on Taxation and Economic Policy warn that slashing income tax revenue may threaten funding for essential public services like education and healthcare.

Kentucky’s Gradual and Conditional Approach

Kentucky is taking a more measured route. A 2022 law enables income tax reductions only when state revenues meet specific targets. The state’s current plan is:

  • 2026: Income tax rate to drop to 3.5%
  • Further cuts: Possible if revenue thresholds are met and legislative approval is secured

A recent law also permits smaller cuts even when financial benchmarks aren’t fully achieved—an approach Democratic Governor Andy Beshear has described as a “bait-and-switch.” Though critical, Beshear allowed the new law to take effect, signaling cautious endorsement.

A Broader National Trend

Mississippi and Kentucky’s efforts are part of a larger movement toward tax reform:

  • Oklahoma is considering a bill to end income tax using revenue-based triggers
  • Missouri may introduce capital gains exemptions
  • New Hampshire and Tennessee have already eliminated taxes on interest and dividends

Yet, experts like Katherine Loughead of the Tax Foundation caution that removing a long-standing revenue stream is not easy. “Once you rely on that money, phasing it out is much more complicated,” she noted.

Conclusion

Mississippi and Kentucky’s aggressive tax reform strategies could redefine state-level fiscal governance. While the promise of economic growth and tax relief is appealing, the true test will be sustainability. With looming economic uncertainties, the success or failure of these initiatives may shape future tax policy across the United States.
