A rare sight is coming to Oklahoma. The last time the Sooner State raised its gas tax rate, the Berlin Wall was still standing, and Congress was debating whether to ban smoking on flights shorter than two hours. Fast forward 31 years, and Oklahoma is finally at it again. On Sunday, the state’s gas tax rate will rise by 3 cents and its diesel tax rate by 6 cents. Both taxes will now stand at 19 cents per gallon—still among the lowest in the country. But Oklahoma isn’t the only state where gas taxes will soon rise.

Following is a statement by Carl Davis, research director at the Institute on Taxation and Economic Policy, regarding the Supreme Court’s decision in South Dakota v. Wayfair. Mr. Davis has authored numerous policy briefs regarding how online retailers that fail to collect sales taxes deprive states of necessary sales tax revenue and maintain an unfair advantage over bricks and mortar retailers.

Many state legislators and regulators are considering expanding state-sponsored gambling by allowing betting on major league sports games. But the revenue states could bring in isn’t worth the risk.

Cash-strapped, tax-averse state lawmakers continue to seek unconventional revenue-raising alternatives to the income, sales, and property taxes that form the backbone of most state tax systems. However, gambling revenues are rarely as lucrative, or as long-lasting, as supporters claim.

The federal Tax Cuts and Jobs Act (TCJA) enacted last year temporarily capped deductions for state and local tax (SALT) payments at $10,000 per year. The cap, which expires at the end of 2025, disproportionately impacts taxpayers in higher-income states and in states and localities more reliant on income or property taxes, as opposed to sales taxes. Increasingly, lawmakers in those states who feel their residents were unfairly targeted by the federal law are debating and enacting tax credits that can help some of their residents circumvent this cap.

An updated version of this blog was published in April 2019. State tax policy can be a contentious topic, but in recent years there has been a remarkable level of agreement on one tax in particular: the gasoline tax. Increasingly, state lawmakers are deciding that outdated gas taxes need to be raised and reformed to fund infrastructure projects that are vital to their economies.

Many state governments are struggling to repair and expand their transportation infrastructure because they are attempting to cover the rising cost of asphalt, machinery, and other construction materials with fixed-rate gasoline taxes that are rarely increased.
