Ranking Unemployment Insurance Taxes on the 2021 State Business Tax Climate Index

Today’s map is the final in our series examining each of the five major components of the 2021 State Business Tax Climate Index. Compared to individual, corporate, sales, and property taxes, unemployment insurance (UI) taxes are less widely understood, but they have important implications for a state’s business climate. A state’s performance on the UI tax component accounts for 9.4 percent of that state’s overall Index score.

Unemployment insurance is a joint federal-state social insurance program that finances benefits for recently unemployed workers through taxes on employers. State UI taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. systems are often quite complex, using variable-rate structures that impose different rates depending on the age of a business, its layoff history, and the health of the state’s UI trust fund, among other factors. All 50 states and the District of Columbia levy UI taxes, but some states structure their systems better than others.

The least-damaging UI tax systems are those that adhere closely to the federal taxable wage base, have low minimum and maximum tax rates on each rate schedule, avoid levying surtaxes or creating benefit add-ons, and have straightforward experience formulas and charging methods. More harmful UI tax systems are those that have high minimum and maximum rates, wage bases that far exceed the federal level, complicated experience formulas and charging methods, and surtaxes or benefit add-ons that go beyond the core functions of the UI program.

On this year’s Index, the states with the best-scoring UI tax systems are Oklahoma, Florida, Delaware, Louisiana, Mississippi, and Ohio. The worst-structured UI tax systems are found in Massachusetts, Kentucky, Idaho, Nevada, Virginia, and Alaska.

The climates created by UI policies can differ greatly. Some states have high statutory minimum and maximum tax rates that apply to large taxable wage bases, while others have low minimum and maximum rates and low taxable wage bases. For example, Arizona, California, Florida, and Tennessee align their taxable wage base with the federal base of $7,000 per employee, while other states extend the taxable wage base far beyond the federal minimum, so that the tax is applied on tens of thousands of dollars of each employee’s wages. (Currently, Washington is the state with the highest taxable wage base, at $52,700.) Rates can only be understood in tandem with wage bases. A 10 percent tax on a $7,000 wage base raises $700, while the same rate on a $49,800 wage base generates $4,980.

Another important consideration is a state’s experience rating formula, which varies from state to state. The concept behind experience ratings is that each employer’s UI tax liability should be adjusted by their own past experience with layoffs. Companies with frequent layoffs face greater liability than companies with steadier track records. But there are different ways that these ratings can be calculated, and different approaches for handling new businesses which have yet to develop a meaningful track record. Some states lean more heavily on aggregate state “experience,” while others focus more specifically on individual businesses. Some use what is called a benefit ratio formula, based on the ratio of unemployment benefits to payroll. Others use a benefit wage ratio formula, or a reserve ratio formula, defined as the balance in the employer’s state unemployment insurance account divided by payroll.

One of the most harmful aspects of UI taxes is that financially troubled businesses, for which layoffs may be a matter of survival, are shifted into higher tax rate schedules when they can least afford to pay a higher tax bill. Failing businesses face ever-higher UI taxes, sending them into further decline. Similarly, surtaxes imposed when UI fund reserves are low mean higher tax liability right when businesses are struggling most. Well-designed UI tax systems emphasize greater stability and predictability.

This issue is particularly important during the ongoing coronavirus crisis. Unemployment compensation funds are inadequately funded in many states, with many states already turning to federal loans (Title XII Advances) to cover shortfalls. The short-term priority should be ensuring that businesses remain viable and able to rehire laid off workers when the health crisis abates, not raising UI taxes immediately to replenish the depleted funds. Many states have already moved to delay automatic rate increases or freeze experience ratings temporarily.
