State Tax Policy 101, Part 1: Income and Unemployment Insurance Taxes

In the first of our six courses, we will explore individual and corporate income taxes plus the timely subject of unemployment insurance taxes.

Income taxes are the largest source of state tax revenue, generating 41 percent of state tax collections nationwide despite nine states forgoing a wage income tax and five states going without a tax on corporate income. Everyone knows about income taxes—but sometimes the details can be murky.

What does it mean to conform to the Internal Revenue Code on a static or rolling basis and why does it matter? What is the difference between a personal exemption and a personal exemption credit? What determines domicile for income tax purposes? How long does someone have to work in a state to pay income taxes there, and how does that affect their tax burden in their home state? What is the purpose of inflation indexing, and why are there so many different approaches to it? Why—and how—do most small businesses pay individual income taxes, and how does this burden compare to those paid by traditional corporations?

How is corporate income apportioned among states? How do you know where a service has been performed for tax purposes? Do economic development incentives work, and how do the different types compare? What is meant by terms like throwback rules, cost recovery, net operating loss carryforwards, or GILTI, and why do they matter?

We will address these questions and more in this informative first course.

Unemployment insurance (UI) taxes, meanwhile, are opaque to even the most senior policymakers. We will walk through the basic structure of unemployment insurance taxation, explaining how each business’s rate is determined, outlining some of the key provisions of UI taxation, and highlighting how the exhaustion of state unemployment compensation funds yields automatic UI tax increases.
