Tariffs and policies lift grocery, housing costs amid shifting consumer habits

States across the country have adjusted their revenue strategies since 1990 by reducing top marginal income tax rates while increasing reliance on sales and consumption taxes. Data compiled by the Institute on Taxation and Economic Policy document this pattern, with top income tax brackets falling in many jurisdictions even as sales tax collections have grown to represent the largest share of state tax revenue according to Census Bureau figures.

This adjustment aligns with efforts in several states to flatten or eliminate income taxes altogether. Lawmakers have cited the need to improve incentives for work, saving, and investment by lowering the direct tax penalty on earnings. Sales taxes, by contrast, apply when income is spent rather than when it is earned, which some analysts argue creates fewer distortions in labor supply decisions.

Lower earners face higher effective rates under heavier sales taxation because they devote a larger portion of their resources to taxable purchases. Yet the broader economic record shows that reductions in income tax rates have often coincided with expanded job opportunities and wage growth that benefit lower-income households through increased employment rather than through redistribution. Historical episodes of marginal rate cuts demonstrate that overall tax collections can rise when economic activity expands.

Corporations have also seen relief from certain income-based levies in these shifts. Proponents maintain that lighter taxation on business income encourages capital formation and productivity gains that ultimately raise living standards across income levels. Critics who focus solely on the distribution of tax payments at a single point in time tend to overlook these dynamic effects on growth.

The trend reflects ongoing debate over whether revenue systems should prioritize taxing current consumption or accumulated earnings. States that have moved toward greater use of sales taxes have done so amid voter pressure for relief on high earners and businesses, even as everyday purchases carry a larger share of the load. Empirical patterns since 1990 indicate that these changes have altered the composition of state budgets without necessarily shrinking total collections when economies respond to improved incentives.
