• Thirteen states aren't offering a tax break on unemployment benefits received last year, according to data from H&R Block.
• The American Rescue Plan, a $1.9 trillion Covid relief bill, waived federal tax on up to $10,200 of jobless benefits per person.
• The remaining states partially or fully exclude benefits from tax. More than a dozen are adhering to the new federal rule. Others don't levy an income tax, for example.

More than a dozen states aren't offering a new tax break on unemployment benefits.

That means taxpayers will need to pay state tax on benefits they received last year, absent any forthcoming changes to state law.

The American Rescue Plan waived federal tax on up to $10,200 of jobless aid per person collected in 2020. The $1.9 trillion Covid relief measure limits that break to individuals and couples whose income was less than $150,000.

State tax

But not all states followed suit.

As of Monday, 13 aren't excluding unemployment compensation from taxes, according to data from tax preparer H&R Block.

They are: Colorado, Georgia, Hawaii, Idaho, Kentucky, Massachusetts, Minnesota, Mississippi, North Carolina, New York, Rhode Island, South Carolina and West Virginia.

The rest don't tax unemployment benefits for a few reasons. Some don't levy a personal income tax. Others specifically exclude unemployment income from state tax. Some, like Indiana and Wisconsin, offer a partial tax break on benefits.

Others adopted the new federal rule. In those areas, up to $10,200 of benefits are excluded from tax, but amounts in excess are taxable. The income-eligibility limit also applies.

Those states are Connecticut, Iowa, Illinois, Kansas, Louisiana, Maine, Michigan, Missouri, North Dakota, Nebraska, New Mexico, Oklahoma, Oregon and Utah, as well as Washington, D.C.

Others like Arizona, Ohio and Vermont haven't officially adopted the federal standard but are doing so administratively — their tax forms allow eligible taxpayers to claim the break, effectively giving them the waiver.

"It's a bit of a mix," said Andy Phillips, a director at H&R Block's Tax Institute, which studies changes in tax law. "Each state has its own legislature and will make its own determinations."

Approximately 40 million Americans received unemployment benefits last year, according to the Century Foundation. The average person got $14,000.

Small tax?

In states that don't offer the unemployment tax break, taxpayers must add back any benefits excluded on their federal tax return when filing their state taxes.

State tax won't necessarily amount to much, though, depending on the respective tax rate.

For example, taxpayers in Colorado pay a flat 4.63% on income, which would include jobless benefits. Kentucky and Massachusetts have a 5% flat tax rate. Mississippi has a top tax rate of 5%, which kicks in for income over $10,000.

Some states have higher rates, though. Hawaii, for example, has a top tax rate of 11%. New York and Minnesota have top rates of 8.82% and 9.85%, respectively. (However, a lower marginal tax rate would likely apply to taxpayers eligible for the federal tax break.)

States that haven't adopted the American Rescue Plan's tax break may still opt to do so.

The Indiana Department of Revenue, for example, said that may occur "depending on the actions of the General Assembly during the remainder of legislative session," which potentially continues until late April, the agency said in mid-March.

The state extended its filing deadline to May 17 to align with the one-month federal extension.

Colorado officials signaled that taxpayers won't get the tax break, however. The state's income tax rules don't incorporate federal changes made retroactively, according to its Department of Revenue. That occurred with the American Rescue Plan, which amended tax rules during the filing season.

"State leaders will continue to review the aspects of the American Rescue Plan Act to find additional ways to support individuals who have experienced unemployment and employers in Colorado who pay unemployment insurance premiums, and to support a strong economic recovery for Colorado," the agency said on March 22.
