You don’t need to take a hot-air balloon ride to see that that inflation also has climbed sky high. But inflation can provide some positive results for taxpayers, thanks to annual adjustments to a variety of tax laws. A key revision is to the income tax brackets that determine how much we’ll owe Uncle Sam. (Photo by Stefan Maritz)
Happy Tax Year 2027! Yes, we are still about two months away from that date, but the IRS has announced annual inflation adjustments for the coming year. They will affect a wide range of tax laws, and details on key ones will part of the ol’ blog’s annual 10-part tax inflation series. Welcome to Part 1, a look at 2027’s individual income tax brackets.
It is that time of year again. Yes, holiday season is here, including Santa’s big day (at least judging by the displays in my local stores and some of my neighbors’ front yards). But it’s also the season when two tax years collide.
Millions of taxpayers spend the last two months of the year looking for any and all ways we can reduce our current tax year’s bill. (Quick, and shameless, promotion: The ol’ blog’s tax tips can help.).
The Internal Revenue Service also is updating tax forms and other material that we’ll use to file this year’s returns next year.
But in addition, the IRS is preparing for the upcoming tax year. And it announces, typically each fall, inflation-related changes to tax laws that will take effect when the calendar flips to Jan. 1.
The IRS announced on Nov. 5 those inflation revisions for the 2027 tax year. The changes affect a wide variety of tax laws, and will apply to 2027 returns that will be filed in 2028.
Early info helps with tax planning.
Yes, the overlap can be a bit confusing since, as noted, many of us are focusing right now on our 2026 taxes that we’ll file in 2027.
But the annual adjustments can help with current tax planning and in making some end-of-year moves that could cut our more immediate tax bills.
Take, for example, your tax bracket. These earning ranges determine how much of your income is taxed at the Internal Revenue Code’s seven tax rates.
The IRS’ annual individual income tax bracket update gives us a preview of where our future taxes will fall. And that knowledge can help shape actions to maximize current tax breaks and/or minimize the current year tax we’ll owe.
Some people might find that postponing a portion of 2026 income and pushing it instead into the next year is advantageous. For these filers, the delayed earnings go into a tax year where more of their income is taxed at a lower rate thanks to 2027’s wider tax brackets.
Others might discover they will likely be in a higher tax bracket next year. So, they might choose to convert all or part of their traditional IRA to a Roth before the current year ends. That way, the tax owed on the converted retirement funds will be at their lower 2026 rate.
Of course, all tax moves should be made in with your overall financial situation and needs in mind. If you are the least bit concerned about what to do, your best tax move is to talk to a tax professional before doing anything.
But a little homework before that tax adviser meeting won’t hurt. The table below, showing the 2027 income ranges for the seven tax rates, is part of that preparatory curriculum.

Progressive tax rates pay off.
As the 2027 and 2026 income tax bracket tables above show, the increase in income amounts into which each of the current seven tax rates apply means you’ll be able to make more money without your tax bill growing so much.
Remember, too, that the tax rates are marginal, not effective. You marginal rate is the tax rate applied to the last dollar you make.
But your effective tax rate is just like it sounds. It is the final, actual, and lower tax rate that applies when you finally tally up what you owe the U.S. Treasury. Tax deductions that reduce your taxable income, and tax credits that cut the tax you owe dollar-for-dollar, help you reach your effective tax rate.
The biggest factor, though, is our progressive tax system.
As the above tables show, your earnings are taxed at all the rates that apply to your income, not just at the final amount of your income.
Applying the just announced 2027 tax brackets, here’s how it works, using a single taxpayer I’ve dubbed Kathy as an example.
Kathy’s 2027 annual income will be $110,000. That would put her next year just into the 24 percent tax bracket. But her tax bill isn’t $26,400, which is 24 percent of $110,000.
Since our taxes are collectively progressively, the first chunk of Kathy’s earnings next year will be taxed at 10 percent. That’s $12,800.
The next tax rate, 12 percent, applies her earnings of $12,801 to $52,025. Her 2027 pay from $52,026 to $109,125 is taxed at 22 percent.
And it’s only that last chunk of Kathy’s earned dollars next year — the amount from $109,126 to $110,000 — is taxed at 24 percent.
That means her taxes breakout in 2027 will be —
$12,800 x 10% = $1,280.00
$39,225 x 12% = $4,707.00
$57,100 x 22% = $12,562.00
$875 x 24% = $210.00
My trusty calculator tells me that the total for Kathy’s 2027 tax bill will be $18,759. That is well below the $26,400 in taxes if you applied her 24 percent marginal tax rate to all her earnings.
And in fact, the smallest portion of Kathy’s total $110,000 income is taxed at her highest rate.
So, Kathy pays Uncle Sam an effective tax rate, which is the average rate of tax on all dollars, that’s a tinch more than 17.3 percent (17.053636364 percent to be precise), and not her marginal tax rate, which is the rate that applies to the last dollar a taxpayer earns, of 24 percent.
Of course, this calculation for Kathy’s 2027 tax bill is a basic, for-illustration-purposes-only example. The ol’ blog’s tax-savvy readers have already realized it doesn’t take into account the previously mentioned deductions or the other tax breaks that Kathy can claim to reduce her ultimate tax bill.
But the example of Kathy’s rough numbers give you an idea of how the wider tax brackets of progressively taxed income will apply to your 2027 earnings.
But wait! There’s more tax inflation numbers!
The tax brackets in this post are just a part of the vast array changes prompted by inflation and cited in the IRS announcement. That release gives you an overview of the coming changes. You also can take a deeper look at the items in the 37-page IRS Revenue Procedure 2026-35.
I am going through that longer IRS document now, and will discuss some of the myriad changes that could affect your 2027 taxes in future posts.
Those discussions will be in my annual 10-part tax-related inflation series that’s been a Don’t Mess With Taxes staple for years. I opted to tackle these yearly adjustments this way instead of as one massive data drop for several reasons.
First, it’s a lot of stuff, and we all have busy lives. And all our tax lives are different. By focusing on the sections separately, you have the option to skip areas that don’t affect you and head straight to the ones that do.
Plus, parsing the IRS adjustments in 10 different posts saves me (and you readers) from having to deal with one massive post.
Second, while we all need to focus on tax planning in a timely manner. The IRS was a bit slow this year in issuing the 2027 amounts, so that crunches us a bit more. But I’m hoping that by spreading the data out over 10 posts in the next week or so, the details will be clearer and we all still will have time to make any tax-saving moves for this year that might be affected by the 2027 figures.
And third and finally, the 10 part series gives me nine more already determined topics on which to blog in the coming days!
Tax inflation preview.
As to that third point, below is a table of contents preview of what’s ahead in the 2027 version of tax-related inflation changes. It also is a good indicator of why I do it as a series.
If you click on the links now (Nov. 6), you’ll find that most of them go to the Don’t Mess With Taxes tax brackets and inflation category page because, well, I’ve yet to post them.
As I publish the 2027 inflation adjusted items, I’ll come back here and update the links.
