Missouri Realtors Donate $1.9 Million to Fight State Income Tax Elimination Amendment

JEFFERSON CITY, Mo. — The Missouri Realtors association has intensified the state’s escalating battle over tax policy, donating $1.9 million in early June to a campaign opposing a constitutional amendment that would eliminate the state’s individual income tax. The contribution signals that the fight over Amendment 5, slated for the August ballot, is rapidly becoming one of Missouri's most expensive and contentious political issues this year. This move highlights the significant uncertainty such sweeping tax proposals create for businesses and individuals alike. Amendment 5 proposes to amend the Missouri Constitution to compel the state legislature to incrementally reduce and ultimately eliminate the individual income tax. The pace of these reductions would be tied to state revenue growth. Once eliminated, the amendment would prohibit the General Assembly from ever re-imposing a state-level individual income tax. Currently, Missouri has a graduated individual income tax with rates ranging from 2% to 4.7%, alongside a 4% corporate income tax. Proponents argue that eliminating the personal income tax will spur economic growth and relieve the financial burden on working families. The Realtors' contribution was made to Missourians for Fair Taxation, the primary political action committee organized to defeat the measure. The timing and amount of the donation are notable, as it came just days after Missouri Promise PAC, the committee backing Amendment 5, reported receiving a nearly identical $1.9 million contribution. That funding came from Missouri Promise Inc., a nonprofit organization whose donors are not required to be publicly disclosed, adding a layer of intrigue to the campaign finance landscape. The near-perfect match in funding—the Realtors' check was reportedly $1 more than the one received by the pro-amendment PAC—underscores the dollar-for-dollar political fight taking shape. Both sides are now heavily capitalized for a statewide campaign to win over voters. John Charton, a representative for the Realtors, stated the group’s opposition is rooted in concerns that the amendment’s language could undermine other constitutional protections that the association has previously championed. Specifically, the Realtors fear the measure could jeopardize a 2010 amendment banning real estate transfer taxes and a 2016 amendment prohibiting the expansion of sales taxes to services. “The real agenda behind Amendment 5 is to trick voters into giving politicians a license to ignore current constitutional taxpayer protections approved by the people,” Charton said. Supporters of Amendment 5 reject this characterization. Joe Lamie, a spokesman for Missouri Promise PAC, argued that the proposal is designed to create a stronger economy and that working families have “shouldered the tax burden for far too long.” For business owners, the appeal of eliminating income tax is obvious, but the practical reality is that state revenue must be replaced. This typically leads to increases in sales taxes, property taxes, or other transaction-based fees that can create new burdens and complexities. We find that businesses thrive on predictability, and a vague constitutional change that could trigger a massive, undefined shift in the state’s entire tax structure is the opposite of predictable.

Opponents have also raised concerns that Amendment 5 is written so broadly that it could weaken the Hancock Amendment, a landmark 1980 provision in the state constitution that requires voter approval for certain tax increases. They point to the fact that even the state auditor’s office could not produce a definitive fiscal note detailing the full financial impact on the state budget, arguing that voters are being asked to approve a change without knowing its ultimate cost. Charton noted that the General Assembly already possesses the authority to reduce and eliminate the income tax through the legislative process, making a constitutional amendment an unnecessary and potentially risky step. The potential disruption to the state budget could also affect specific tax relief programs that many Missourians rely on. For example, the Missouri Property Tax Credit provides relief to senior citizens and fully disabled individuals, offering a credit of up to $1,100 for homeowners and $750 for renters to offset property tax payments. The funding for this and other state-run programs depends on a stable revenue stream, which would be fundamentally altered by the elimination of the state's largest source of general revenue. Ultimately, business owners in Missouri must look past the headline promise of 'no income tax' and ask critical questions about what comes next. The stability of the state's fiscal environment is paramount for long-term investment and growth, and that stability is now a central question in this debate. With both sides now armed with significant funding, Missouri voters can expect a barrage of advertising and campaigning in the months leading up to the August election. The outcome will hinge on whether voters are persuaded by the promise of economic stimulus through tax elimination or the warnings of fiscal uncertainty and unintended consequences.
