The Midlife Money Checklist: 10 Things to Do Before the Year Ends

December in my house means three kids, a packed calendar, and a budget that suddenly has to stretch around holidays. It is also the month I sit down and do a short list of money moves that quietly make next year easier.

Most of these take less than an hour. Several have a hard December 31 deadline, which means if you wait until January, the opportunity is simply gone. And in your 40s and 50s, these small moves add up fast. You are in your peak earning years, and every tax-advantaged dollar you save now has decades left to grow.

Here is the checklist I use. Pour a coffee and work through it one item at a time.

1. Push extra money into your 401(k) before the last paycheck

401(k) contributions count for the year they come out of your paycheck, so December 31 is the deadline. If you have room left, ask HR or log into your benefits portal and raise your contribution for your final paychecks of the year.

For 2026, the limits are:

• $24,500 if you are under 50

• $32,500 if you are 50 or older (that includes an $8,000 catch-up contribution)

• $35,750 if you turn 60, 61, 62 or 63 this year, thanks to a special higher catch-up of $11,250

One new wrinkle: if you earned more than about $150,000 in wages last year, your catch-up contributions may now have to go in as Roth (after-tax) money. Your plan administrator can tell you how your plan handles it.

👉 Even an extra 2% for the last two paychecks is real money invested before the year closes.

2. Plan your IRA contribution (you have until April)

Unlike a 401(k), you can make your 2026 IRA contribution until the tax-filing deadline in April 2027. The limit is $7,500, or $8,600 if you are 50 or older.

Still, I like to decide now. Pick the amount, set up an automatic transfer, and you will not be scrambling in April. If you are not sure whether a Roth or traditional IRA fits you better, start with your income: in 2026, the ability to contribute directly to a Roth IRA phases out between $153,000 and $168,000 for single filers and heads of household.

👉 Decide in December, fund by April, and let the money start working sooner.

3. Spend down your FSA

A health Flexible Spending Account is usually use it or lose it. Some plans offer a grace period or let you carry over a small amount, but many do not. Check your balance now and book the eye exam, refill the prescriptions, or stock up on eligible items like sunscreen, first-aid supplies and contact solution.

👉 Leaving FSA money on the table is the same as throwing away part of your paycheck.

4. Top up your HSA

If you have a high-deductible health plan, a Health Savings Account is one of the best accounts available: money goes in tax-free, grows tax-free, and comes out tax-free for medical costs. For 2026 you can contribute up to $4,400 for self-only coverage or $8,750 for family coverage, plus an extra $1,000 if you are 55 or older. You have until April 2027 to finish your 2026 contributions.

👉 If you can afford to pay small medical bills out of pocket, let your HSA grow as a second retirement account.

5. Review your open enrollment choices carefully

Open enrollment usually happens in November, and it is easy to just click "keep my current plan." Do not. Your 40s and 50s are when life insurance and disability insurance matter most, especially if people depend on your income.

As a single mom of three, this is the one I take most seriously. If something happened to me, my kids need a plan. Look at:

• Life insurance: Is the coverage enough to replace your income for the years your kids still need you?

• Disability insurance: Your ability to earn is your biggest asset. Make sure it is protected.

• Health plan: Compare total yearly cost (premiums plus expected out-of-pocket), not just the premium.

👉 Ten minutes of comparing plans can save hundreds of dollars and protect your family.

6. Update your beneficiaries

This is the most overlooked item on the list, and one of the most important. Beneficiary designations on your 401(k), IRA and life insurance override your will. If you have been through a divorce, remarried or had children since you opened those accounts, the wrong person could inherit your money.

As a divorced mom, I would put this at the very top of your list (and if you are in the middle of that transition, see my guide on how to rebuild your finances after divorce). Log into each account and confirm the names are right. It takes about five minutes per account.

👉 Your will does not control your retirement accounts. Your beneficiary forms do.

7. Rebalance and look for tax losses

Markets move, and your mix of investments drifts. Year-end is a good time to check whether your stock-and-bond mix still matches your goals and move it back if it has drifted.

If you invest in a regular taxable brokerage account, look for investments that are down. Selling them before December 31 can create a loss that offsets your gains, plus up to $3,000 of ordinary income. Just do not buy the same investment back within 30 days, or the loss will not count (the IRS "wash sale" rule).

👉 Rebalancing keeps your risk where you want it. Tax-loss harvesting turns a bad year into a tax break.

8. Make your charitable gifts by December 31

Gifts to charity need to be made by December 31 to count for this tax year. There is also a new benefit starting in 2026: even if you take the standard deduction, you may be able to deduct up to $1,000 in cash gifts to qualified charities ($2,000 for married couples filing jointly). Keep your receipts, and ask your tax preparer how it applies to you.

👉 If you were going to give anyway, giving before year-end can lower your tax bill.

9. Fund your kids' 529 plans

If you are saving for college, many states give you a state income tax deduction for contributions to your state's 529 plan, and the deadline is often December 31. Rules differ by state, so check yours.

With three kids, I think about this balance a lot. My rule: retirement comes first, because your kids can borrow for college but you cannot borrow for retirement. Once retirement savings are on track, 529 contributions are a powerful next step.

👉 If your state offers a deduction, a December 529 contribution can pay you back in April.

10. Check your numbers and set next year's goals

Finally, take a snapshot of where you stand:

• Net worth: Add up what you own and subtract what you owe. Then see how it compares to the average net worth by age.

• Savings: Compare your retirement savings to the benchmarks for your age.

• Emergency fund: Is it in a high-yield savings account earning real interest?

• Credit report: Pull your free reports at AnnualCreditReport.com and look for anything you do not recognize.

Then write down two or three money goals for next year. Not ten. Two or three you will actually do.

👉 You cannot steer what you do not measure.

Final Thoughts

The end of the year does not need to be a financial scramble. Work through this checklist in a weekend or spread it across December, and you will start next year with lower taxes, better protection and more money invested for your future.

If you are in your 40s or 50s and feel behind, remember: it is not too late to build wealth after 40. The goal is not perfection. It is freedom, built one smart decision at a time. And if you want to know what to avoid along the way, read the biggest financial mistakes people make in their 40s.
