Idaho will become 10th individual flat-tax state in 2023

Gem State lawmakers, however, recently went the other direction, lowering the state's top personal income tax rate and making it the lone flat tax amount collected on individual earnings starting in 2023.

I've spent most of my earnings life in no-individual-income tax states. I was born, grew up, and got my first jobs in Texas.

After a stint in Maryland, which collects state and local income taxes, the hubby and I moved to Florida, another no personal income tax state. Then we came home (he's a native Texan, too) to the Lone Star State.

Those years in Maryland were great, but they also gave me an understanding of why folks hate paying tax on their earnings to multiple government collectors.

And there are a lot of U.S. residents in that crowed state tax boat.

A few no-tax places: Most U.S. residents pay state income taxes. A lot of them, like my former Maryland neighbors, also pay local taxes on their earnings.

Only eight states don't levy a personal income tax. They are my current home of Texas, former home of Florida, and Alaska, Nevada, South Dakota, Tennessee, Washington, and Wyoming.

Wealthier Washington state individuals do have pay a newly instituted and still being challenged 7 percent capital gains tax.

But across the country in New Hampshire, individuals who've long been paying tax on dividends and interest are watching that tax fade away. The Granite State's tax is being phased out, and when Jan. 1, 2027, arrives, New Hampshire will become the ninth no-personal-income-tax state.

The remaining states follow the Internal Revenue Service's lead and tax individual income. Most — 32 and Washington, D.C. — are strict IRS tax method acolytes; they have graduated tax rates.

Flat taxers hitting 10: Nine, however, use a flat tax system.

That flat tax number will become 10 — and the graduated rates and brackets list drop to 31 + D.C. — next year.

In 2023, Idaho is joining the flat state income club.

The Gem State's one rate will be 5.8 percent. Idaho's lone rate also will be the highest among the current flat tax states. Those states and their 2022 tax year rates are:

Colorado, 4.55%
Illinois, 4.95%
Indiana, 3.23%
Kentucky, 5.0%
Massachusetts, 5.0%
Michigan, 4.25%
North Carolina, 4.99%
Pennsylvania, 3.07%
Utah, 4.85%

Still, as advocates of the change would argue, you've got to start somewhere.

Flat tax rate pros and cons: The battle of which is best and for whom has been raging for, probably as long as income taxes have been levied.

Man in suit driving road equipment over taxes to flatten themBoth sides can agree on one thing. A flat tax is simpler.

After that, though, there's no common ground.

Flat tax supporters argue that it helps grow economies and encourages wealth accumulation because higher income earners have more money to invest in their or other companies.

They also point to the end of loopholes added to state and federal tax codes at the behest of lobbyists. Personal aside: I don't think loopholes will ever be plugged.

Pro flat-taxers also contend that the simplicity will help reduce fraud. Again, color me skeptical about anything stopping tax cheats.

Opponents of a flat tax argue that it places an unfair burden on low-income earners, since people with the lowest income pay the same tax rate as the people with the highest income in the state.

Proportionally, goes the argument, the $1,500 that represents 5 percent of $30,000 is a bigger loss of spending money to that earner than the $6,500 that 5 percent takes from a person making $130,000.

They also argue that the usually lower tax rates could negatively affect state revenues and projects the tax money funds.

Growing flat-tax trend: You can expect those arguments to continue in more states.

While 10 flat tax states aren't many, the trend toward that system has accelerated recently. Idaho is the fifth state in the last two years to move from a graduated rates personal tax system to a flat tax.

That's pretty amazing since, as Jared Walczak, vice president of state projects at the Tax Foundation, notes, "In more than a century of state income taxes, only four states have ever transitioned from a graduated-rate income tax to a flat tax."

"In what is already a year of significant bipartisan focus on tax relief, 2022 is also launching something of a flat tax revolution," wrote Walczak in a recent article for the Washington, D.C.-based tax policy organization.

Just how big will this flat tax revolution become? We'll get a better idea in a couple of months after the Nov. 8 midterm election results.

TAX-SAVVY WAYS 
TO WRAP UP 2026

It’s over! With October’s extended filing deadline behind us, it is now time to focus on year-end moves to reduce your 2026 tax bill. 

You’ll find ways to do just that on the Tax Tips page (see the More Tax Posts drop-down menu at the top of the blog), as well as the separate tax tip pages for each month, notably October through December. If you’re on the Tax Tips page, you’ll find a monthly list at the end of this column. If you’re on another blog page, you can head straight to the October tips; at the bottom of that tips page you’ll find links to all the other 11 months’ collections of tax advice.

Not to spoil what you’ll find in that tax advice, but it does cover such things as tax deductions for charitable donations, investment moves that could reduce tax due, and ways to max out your tax-favored retirement savings. 

Finally, as the year winds down, things get hectic. There are lots of other things to occupy our time, like the much more fun upcoming holidays. But don’t lose sight of taxes, since timing is key. To be of use, most tax moves must be made by the end of the tax year. That’s Thursday, Dec. 31, which also is the last business day of the year. 

So that you don’t miss that final tax year deadline, also keep an eye on the countdown clock below. It will keep you on top of just how much time is left to make important, tax-saving moves. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
