Inflation affects state taxes, too

November 22, 2014

The Internal Revenue Service recently released its figures on how inflation will affect many federal tax provisions in 2015.

But the cost of living also affects states. And these jurisdictions' tax departments deal with annual price increases in different ways.

Thanks to the Tax Foundation map below, you can see the various state tax approaches to inflation.

The Washington, D.C.-based tax think tank notes that:

  • 23 states fully index brackets to inflation; this number includes the nine states (each marked by an asterisk and listed in the "Notes" box in the map) with single-rate income taxes, which are by definition inflation-indexed).
  • California and Oregon partially index their brackets.
  • 19 states, along with the District of Columbia, with multiple brackets do not index at all.

When tax brackets aren't indexed for inflation, note the Tax Foundation's Scott Drenkard and Richard Borean, taxpayers can encounter bracket creep. This happens when a higher income bumps a taxpayer into the next tax bracket, even if that higher income is merely keeping pace with inflation.

Practically speaking, absent inflation adjustments many taxpayers face a tax increase without any legislation being passed.

Have you seen inflation's effects, for good or ill, on your state taxes?

Tax Season 2026 Continues!

We made it. Tax Day 2025 is finally over. For most of us. When the filing season started on Jan. 26, millions who were expecting refunds filed immediately. Most of us got our returns to the Internal Revenue Service by April 15. But plenty of taxpayers also got extensions. They are looking at an Oct. 15 filing deadline.

Those procrastinating filers aren’t a problem. In fact, the IRS appreciates taxpayers who take time to fill out their 1040 forms correctly. It also is grateful that tax submissions are spread out a bit, especially now that the IRS is a leaner agency. Processing returns is easier when they arrive throughout the year instead of in massive bunches.

But enough about Uncle Sam’s tax collection issues. The focus now is on all y’all who filed for extensions, giving you another six months to complete your return. Since your new mid-October due date will be here before you know it, let’s get started now on meeting it.

The ol’ blog is here to help you finish up your extended Form 1040. You can start with January’s tax tips page, which has links to the rest of the year’s tips by-month collections. You also can peruse various tax categories for more tailored advice by clicking on the More Tax Posts drop-down menu at the top of this (and every) page.

And to make sure you don’t miss your new filing deadline, the count-down clock below will let you know just how much time you to file by Oct. 15. At the latest.e. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
