Four retirement decisions that look different in 2026 than they did last year

Ten years ago, the retirement playbook for a working woman was simple enough on paper. Max the 401(k) when you could, take Social Security around 65 or 66, and trust that the tax code would sort itself out later.

In 2026, the full retirement age for Social Security finished its long climb, catch-up contributions for higher earners have to be made a very specific way, and how your savings are taxed matters more than how much you save.

None of that means the old advice was wrong. It means the defaults have moved, and a handful of decisions you might have been making on autopilot deserve a fresh look this year.

Decide When You’ll Actually Claim Social Security

For anyone born in 1960 or later, the full retirement age is now 67. That finishes a phase-in that started back in the 1980s, and it changes the math on early claiming. Take benefits at 62 instead of 67, and your monthly check is permanently smaller for the rest of your life.

That trade-off matters more for women than the headlines usually acknowledge. Women live longer on average, are more likely to be the surviving spouse, and are more likely to have stepped out of the workforce for caregiving at some point. A reduced benefit compounds across a longer retirement, and it often becomes the household floor once a partner dies.

The decision isn’t 62 versus 70 in the abstract. It’s what does your household income actually look like in your early sixties, and can you bridge to a later claim with other assets? If you can, delaying usually wins. If you can’t, claim early with your eyes open, not by default.

Decide Whether Your Catch-Up Contributions Should Be Roth

Starting January 1, 2026, if you’re 50 or older and earned more than $150,000 in FICA wages last year, any catch-up contributions to your workplace plan have to go into a Roth (after-tax) bucket. Pre-tax is off the table. And if your plan doesn’t offer a Roth option, you may not be able to make catch-ups at all until it does.

For a lot of women in their peak earning years, this is a real planning moment, not a paperwork one. Paying tax now on catch-up dollars means those dollars grow and come out tax-free later. That can be a great deal if you expect your retirement tax rate to look similar to or higher than today’s, and a worse one if you’re at the top of your career and expect to spend from a much smaller income later.

A few things worth working through before you set your 2026 elections:

Your plan’s Roth option. Confirm your 401(k) or 403(b) actually offers Roth deferrals. If it doesn’t, ask HR whether that’s changing, and consider a Roth IRA in parallel.
Your expected retirement tax rate. Compare your current marginal rate to a realistic estimate for retirement, including Social Security and any pension income. The gap between the two is the whole ballgame.
Your withholding. Roth contributions come out of after-tax pay, so your take-home may drop unless you adjust other savings to match.

Decide How Aggressively to Use the 60-to-63 Window

There’s a small, powerful piece of the current retirement rules that hasn’t gotten the attention it deserves. Workers who turn 60, 61, 62, or 63 in a given year can make a larger “super” catch-up to their 401(k), 403(b), or governmental 457(b) plan instead of the standard age-50 catch-up. It’s a four-year window that then closes.

For a woman who spent part of her career on a lower savings rate, took a break, or is coming into her highest earnings late, that window is a genuine gift. It’s also the kind of thing that only helps if you plan for it. Cash flow at 60 doesn’t magically expand to absorb thousands of additional dollars in deferrals. You have to decide, ahead of time, what you’re going to redirect.

If you’re a few years out from that window, the decision now is where the money will come from later. If you’re already inside it, the decision is whether to use every dollar of the enhanced limit or split it with other goals like paying down a mortgage.

Decide Who’s Actually Doing the Math With You

The through-line in all of this is that retirement is less about a single number and more about a sequence of specific decisions inside a specific tax code, in a specific year. That’s harder to do alone than it used to be, and it’s harder to do with a generic online calculator that hasn’t caught up to the new rules.

If your current setup is a workplace 401(k), a spouse who handles the taxes, and a vague plan to “figure it out closer to 60,” it’s worth pressure-testing this year. A fee-only fiduciary planner will run the numbers on Roth versus pre-tax, model different Social Security claiming ages against your actual life expectancy, and stress-test what happens if you retire earlier or later than planned. Independent firms like Lighthouse Financial combine investment strategy with tax planning so those decisions get made together instead of in separate rooms.

You don’t need to hire anyone tomorrow. You do need to know who’s going to help you decide, and when. The rules that framed retirement for your mother, and even for your older sister, aren’t the rules you’re retiring under.
