State tax revenue is down a lot since last year. The latest comparable data from Census’s QTAX survey is for the 2nd quarter of 2023, and it shows a massive hit: state tax revenue was down 14% from the same quarter in 2022, which is about $66 billion. Almost all of that decline is from income tax revenue, specifically individual income tax revenue which is down over 30% (almost $60 billion). General sales taxes, the other workhorse of state budgets, is essentially flat over the year.
That’s a huge revenue decline! So, what’s going on? In some states, there has been an attempt to blame recent tax cuts. It’s not a bad place to start, since half of US states have reduced income taxes in the past 3 years, mostly reducing top marginal tax rates. But that can’t be the full explanation, since almost every state saw a reduction in revenue: just 3 states had individual income tax revenue increases (Louisiana, Mississippi, and New Hampshire) from 2022q2 to 2023q2, and they were among the half of states that reduced rates!
To get some perspective let’s look at long-run trends. This chart shows total state individual income tax revenue for all 50 states (sorry, DC) going back to 1993. I use a 4-quarter total, since tax receipts are seasonal (and because states sometimes move tax deadlines due to things like disasters, a specific quarter can sometimes look weird). And importantly, this data is not inflation adjusted. Don’t worry, I will do an adjustment further below in this post, but for starters let’s just look at the nominal dollars, because nominal dollars are how states receive money!
