The North Carolina General Assembly has passed bills to place six constitutional amendments on the ballot on November 6. A simple majority vote puts these ill-advised amendments into the state Constitution.
The purpose of these amendments is to get right-leaning voters to the polls for the crucial mid-term elections. Take Senate Bill 677, a constitutional amendment to protect the right to “hunt, fish, and harvest wildlife.” Is there some threat to these activities? Nope. But it sure sounds like something that the GOP’s base would want to come out to the polls to support.
Other than cluttering up the Constitution, SB 677 sounds harmless enough. But some of the other amendments are terrible for the future of North Carolina. I’m going to analyze one of them, a cap on state income tax rates.

Senate Bill 75 caps the state income tax at 7 percent of net incomes. This replaces the Constitution’s current cap of 10 percent. The recent history of N.C.’s income tax rates is necessary context for understanding SB 75. Here are the top marginal tax rates since 2001:
This percentage is the percentage of the next dollar earned paid by top earners. Until 2014, lower-earning taxpayers had a lower marginal tax rate, but N.C. switched to a flat-rate tax in 2014, meaning that everyone, regardless of earnings, pays the same marginal rate. This switch lowered the marginal rate for all taxpayers, with married couples earning over $100,000 getting the largest reduction (1.95 percent) and lower-earners getting the smallest reduction (0.2 percent). This was a big gift to our highest-earning taxpayers.
SB 75 was filed in February 2017, proposing an amendment to cap the tax rate at 5.5 percent, a hair above the current income tax rate. The Senate passed this bill in March 2017, but the House failed to approve it. The House reconsidered it in June 2018, replacing the 5.5 percent cap with a 7 percent cap and passing the bill on June 28. The Senate passed the revised bill the same day, placing the 7 percent cap in front of voters.
The original SB 75 would have locked in the entire big gift to high earners incorporated into the tax code in 2014 and would have prevented any increases in overall tax rates. The revised version is less onerous in that it locks in only a portion of the gift to high earners and is not quite as tight a constraint on tax rates.
Nevertheless, SB 75 is a bad idea.
Why is this cap bad?
Income tax caps are bad policy because a state’s revenue needs can vary unpredictably over time and income tax caps eliminate flexibility. If income taxes can’t be raised to meet needs, a state’s primary alternative is to raise sales taxes (and various usage fees).
Sales taxes (and usage fees) impact poor people much more than they impact wealthy people: Poor people must spend most of their income, subjecting most of their income to sales tax, while wealthier people spend a much lower percentage of their income.
Moreover, the specific cap passed in SB 75 locks in rates that are lower than recent historical rates and the new flat-rate tax structure shifts more of the income tax burden to lower earners.
Other states such as Kansas that have lowered tax rates dramatically have had poor results. We are already seeing hints of the impact in N.C. with a precipitous drop in inflation-adjusted per student spending in public schools.
Foolish to experiment in amendments
It is one thing to try an experiment, however ill-advised, but something entirely different to enshrine an experiment in the state Constitution. A constitutional income tax cap below historical rates ties our future legislators’ hands. If they need to address the state’s future needs, they won’t be able to do so by returning even to historical levels of income tax; their only recourse will be to raise sales taxes, which will hurt poor people more than wealthy people.
This is foolish. Unfortunately, it is also consistent with the N.C. GOP’s trend to both reduce spending on public services and to shift the burden of taxes away from their wealthier constituents.
