Only 14 states adjust their income tax brackets for inflation

November 26, 2013

If you're hitting the road to a new destination this Thanksgiving holiday, you've probably been looking at a road map.

Take a tax break from those red and blue highways and check out the even more colorful Tax Foundation's map of possible tax bracket creep across the United States.

State Income Tax Brackets and Inflation Adjustments_Tax Foundation

Bracket creep is as icky as it sounds.

It flares up, notes the Washington, D.C.-based group, when tax brackets aren't indexed for inflation. Without that adjustment, as a taxpayer's earnings increase, that added money will be taxed at higher rates.

You could contract this terrible tax affliction if you live in one of the map's orange-tinted states.

Unlike the Internal Revenue Service, which adjusts the federal income tax brackets each year to account for inflation, those 20 states and the District of Columbia do not index their multiple tax brackets for inflation.

Only 12 states — those in green in the map above — fully index brackets to inflation, say Tax Foundation analysts.

They are Arkansas, Idaho, Iowa, Montana, Maine, Minnesota, New York, North Dakota, Rhode Island, South Carolina, Vermont and Wisconsin.

California and Oregon, shown in purple, partially index their tax brackets.

And, notes Tax Analysts, New York's indexing is temporary.

Thank goodness I live in Texas, one of the gray states. The Lone Star State, along with Alaska, Florida, Nevada, South Dakota, Washington and Wyoming, don't tax any individual income.

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.)
