2027 Tax Brackets Explained: Bracket Creep, 401(k) Limits and Ways to Get Ready

Michael Henaghan, managing editor at Wolters Kluwer, explains the projected federal tax brackets for 2027, how they are calculated, why “bracket creep” can quietly push taxpayers into higher brackets even if real income has not increased, and what is expected to change in retirement contribution limits, including the 401(k) increase to $25,500.

Michael, it’s great to see you. Thanks for joining us.

I’m glad to be here. Taxes are never a fun subject for anyone, especially when April 15 comes around.

Still, you and your team have done a lot of work here, and it’s important to understand what may be ahead for taxes in 2027. You’ve also spent time sorting through the brackets.

Before we get into the details and talk about retirement figures and other numbers, can you walk us through the process you use to calculate them?

Michael Henaghan, Managing Editor at Wolters Kluwer

Sure. For someone like me, it’s actually pretty interesting. It’s a fun spreadsheet exercise.

It is not really a mystery. The whole system is built into the tax code.

At a basic level, the Internal Revenue Code sets the base amounts for all of these figures. There are more than 100 inflation-adjusted amounts that the IRS updates each year. The code establishes a starting amount and a base year.

From there, the process is math. You take a CPI rate over a 12-month period and compare it with the CPI rate for the same 12-month period in the base year.

Then you divide the new CPI rate by the base-year CPI rate and multiply that result by the base amount.

There is also some rounding involved, and that gives you the new number. It is a bit more complicated than that, but that is the general idea.

I may be simplifying it too much, but in the end it is basically ninth-grade math.

Jeffrey Snyder, Broadcast Retirement Network

Right, and I appreciate that. I also don’t think it’s simple enough for me to just punch into a calculator. But I do want to ask about some of the tax code changes.

I’m not asking for specific advice, but what should taxpayers know about the new brackets?

What should they be watching for, and then we can talk about what they might want to do.

Michael Henaghan, Managing Editor at Wolters Kluwer

The main reason for updating the brackets is to prevent something called bracket creep. To use a simple example, say a married couple makes $120,000 a year. That would place them in the 22% bracket.

There is a common misunderstanding about how tax brackets work. People hear that they are in the 22% bracket and assume all $120,000 is taxed at 22%.

That is not how the system works. It is progressive. The first portion is taxed at one rate, the next portion at another, and only the income above a certain level is taxed at the higher rate.

Bracket creep happens when those brackets are not adjusted each year. If your income rises only because of a cost-of-living increase, you may end up paying more tax even though you are not really earning more in economic terms.

For example, if income rises from $120,000 to $125,000, more of it may fall into the 22% bracket. But if that increase is only keeping pace with higher prices for things like milk, gifts, and eggs, you are not actually getting ahead economically.

Without bracket adjustments, you end up paying more tax on essentially the same real income. The brackets end up reflecting what is happening in the broader economy.

Inflation is higher than most people would like, and that shows up in the tax code. It is reflected in the brackets, the standard deduction, and other parts of the system.

The bottom line is that higher inflation is generally showing up in the tax code as well.

Jeffrey Snyder, Broadcast Retirement Network

That is the reality we are dealing with, and affordability remains a challenge for many people. Since these are 2027 brackets, I’m assuming they apply to income earned from the start of that year through the end of that year. Is that correct?

Michael Henaghan, Managing Editor at Wolters Kluwer

That is absolutely correct.

Jeffrey Snyder, Broadcast Retirement Network

Okay. So with this information coming out, what should Americans be thinking about? I’m not asking for tax advice, but should they consider reviewing payroll withholding, W-4 forms, and other paperwork they may have filled out before? Would it make sense to review those items with a tax advisor?

Michael Henaghan, Managing Editor at Wolters Kluwer

That is always good advice. It is smart to review withholding, especially at the beginning of the year, to make sure everything lines up.

But the reality is that people generally earn what they earn. For people who can defer income, that is usually a good idea, though we are not giving tax advice here.

There is not a huge amount of room to maneuver just by looking at the brackets alone. You are going to make what you are going to make, and you are going to pay what you are going to pay.

What matters more in many cases are things like business deductions. For businesses, the Section 179 deduction is one example, and it is also adjusted for inflation.

For individual taxpayers, a lot of the planning comes down to retirement decisions.

We can project what the IRA contribution limit is likely to be, and we can also project the 401(k) contribution limit. Eventually the IRS will release that information too.

The benefit of projecting it is that people get the information earlier and can make decisions in advance. Practitioners can also use the figures earlier in the year and help clients plan ahead.

That may help someone decide whether to max out an IRA contribution now or later. If money is limited, a higher contribution cap can create a little more room next year.

Jeffrey Snyder, Broadcast Retirement Network

I like that you brought up deductions. Can we spend a moment on employee benefits, including IRAs and the 401(k), 403(b), and 457(b) limits?

Are those limits projected to rise meaningfully, or only by a small amount?

Michael Henaghan, Managing Editor at Wolters Kluwer

That is one of the tricky parts of inflation adjustments. It is not as simple as assuming that if inflation is 3.5%, every number will rise by 3.5%.

Because of the way these calculations work, and because of rounding, the result is not always perfectly linear.

For example, the 401(k) contribution limit for the prior year was $24,500. We are projecting that it will rise to $25,500.

That is a fairly large increase. If inflation is around 3%, that is more than a 3% gain.

But the increase comes down to rounding. The limit rounds down to the nearest $500. So if the unrounded figure was just under $25,000 one year, it could have become $24,500 after rounding.

With the next adjustment, the unrounded number might move to $25,501. That would create a $1,000 jump in the published cap even though the underlying math only produced a much smaller increase.

The IRA contribution limit is different. It was $7,500 and is projected to remain $7,500.

That smaller number means the adjustment has less effect. The point is that rounding creates odd results.

That can be frustrating, because people see the projected numbers and then ask why they do not match the headline inflation rate they have heard about. The answer is that rounding matters, and the increases are not always uniform.

Jeffrey Snyder, Broadcast Retirement Network

That makes sense. I suppose it is close enough for the information people need, including practitioners. And even the government later revises labor data over time, so we all have to allow for some flexibility.

To close, since these are projections and the IRS has the final say, when does the agency usually weigh in? And I assume your team may revise things after that as well.

Michael Henaghan, Managing Editor at Wolters Kluwer

We expect those numbers to be released by the IRS soon. I have been checking this morning, and they have not come out yet.

There are two major groups of numbers, each based on different calculations.

The larger group includes the tax brackets, standard deduction, and similar items. Those have appeared as early as early October and as late as the second week of November.

The retirement-related figures come from a separate batch. They use an additional month of CPI data, and those have typically appeared from mid-October to mid-November.

The IRS already has the data it needs. It is simply a matter of completing its process.

Jeffrey Snyder, Broadcast Retirement Network

I’m sure they are busy with audits and other work, especially with a recent filing deadline now behind them. Michael, this has been a great conversation and very useful information.

I think many people do not realize how these brackets are adjusted. Thank you for joining us, and we look forward to having you back soon.

Michael Henaghan, Managing Editor at Wolters Kluwer

I would be happy to come back. It was great being here. Thank you.
