The single most important thing you can do with your retirement finances right now is pause, look at the calendar, and act. With exactly six months left in 2026, mid-year is the ideal moment to review your Social Security strategy, check your Required Minimum Distributions (RMDs), audit your Medicare costs, and shore up your tax picture — before year-end deadlines sneak up on you. Think of this as your financial half-time: the score isn’t final yet, and there’s still plenty of time to adjust your game plan.

Why does mid-year matter so much for retirees?

Most financial deadlines cluster at the end of the year, which means many retirees scramble in November and December. But acting in late June gives you a six-month runway to fix mistakes, shift income, and avoid costly penalties. Procrastination is expensive when you’re living on a fixed income — a missed RMD, for example, triggers a 25% excise tax on the amount you should have withdrawn. Starting your checklist today means finishing the year with more money in your pocket.

What are the 15 mid-year money moves retirees should make?

Here’s your complete checklist. Work through it at your own pace — even checking off half of these items will put you ahead of most retirees.

Social Security & Income

  1. Review your Social Security claiming age. If you haven’t claimed yet, every year you delay past your full retirement age (currently 67 for those born in 1960 or later) adds roughly 8% to your benefit. Run the numbers at ssa.gov.
  2. Check how much of your Social Security is taxable. Up to 85% of your benefit can be taxed if your combined income (adjusted gross income + nontaxable interest + half your Social Security) exceeds $34,000 for singles or $44,000 for couples. Knowing your number now lets you manage income before December 31.
  3. Assess whether a Roth conversion makes sense this year. If your income is lower than usual in 2026, converting some traditional IRA money to a Roth IRA locks in today’s lower tax rate and reduces future RMDs.
  4. Look at your overall income mix. Wages, pension, dividends, and IRA withdrawals all affect your tax bracket differently. A quick review with a tax professional can reveal surprising savings.

RMDs (Required Minimum Distributions) 5. Confirm your 2026 RMD amount. If you turned 73 or older this year, you must take your RMD from traditional IRAs and most workplace retirement accounts by December 31, 2026. Your custodian (the bank or brokerage holding your account) should calculate it for you, but verify the number yourself. 6. Check whether the SECURE 2.0 Act changes your timeline. Under rules updated in 2025 and continuing into 2026, Roth accounts inside workplace 401(k) plans no longer require RMDs during the owner’s lifetime. If your plan hasn’t updated its records, flag this with your plan administrator. 7. Set up automatic RMD withdrawals now. Waiting until December is risky — holiday processing delays can cause you to miss the deadline. Schedule withdrawals for October or November. 8. Consider a Qualified Charitable Distribution (QCD). If you’re 70½ or older, you can donate up to $105,000 directly from your IRA to a qualified charity. It counts toward your RMD and is excluded from your taxable income — a double win.

Medicare Costs 9. Calculate your IRMAA risk for 2028. IRMAA (Income-Related Monthly Adjustment Amount) is a surcharge added to your Medicare Part B and Part D premiums if your income exceeds certain thresholds. Here’s the catch: Medicare uses your income from two years ago. So your 2026 income will determine your 2028 premiums. If you had an unusually high-income year — say, from a home sale or large IRA withdrawal — you can file Form SSA-44 to appeal. 10. Know your current Part B premium. The standard Medicare Part B premium in 2025 is $185.00 per month, and 2026 figures are in a similar range. Log into Medicare.gov or check your Social Security statement to see exactly what you’re paying. 11. Review your Medicare Advantage or Supplement plan during Open Enrollment. The Annual Enrollment Period runs October 15 – December 7. Use your mid-year review to research alternatives now, so you’re not deciding in a rush. 12. Check your prescription drug costs. The Inflation Reduction Act caps out-of-pocket drug costs for Medicare beneficiaries. Make sure your current plan is applying the cap correctly.

Tax & Savings Moves 13. Harvest tax losses in your investment accounts. If some of your non-retirement investments have dropped in value, selling them now can offset capital gains elsewhere — a strategy called tax-loss harvesting. You can repurchase similar (not identical) investments after 30 days. 14. Max out your HSA if you’re still eligible. If you’re under 65 and enrolled in a high-deductible health plan, your 2026 HSA contribution limit is $4,300 for individuals and $8,550 for families (plus a $1,000 catch-up if you’re 55 or older). HSA money rolls over forever and can be used tax-free for Medicare premiums in retirement. 15. Update your beneficiary designations. This isn’t glamorous, but it’s critical. Check every account — IRAs, 401(k)s, life insurance, annuities — and confirm the beneficiaries listed still reflect your wishes. A mid-year review is the perfect time.

How should I prioritize if I can’t do all 15 moves at once?

Start with the items that have hard deadlines or the biggest financial consequences. RMD compliance, IRMAA management, and Social Security timing tend to have the highest dollar impact for most retirees. If you have an IRA and are over 73, your RMD is non-negotiable — missing it costs you 25% of the amount you should have withdrawn. After that, work on income management to protect your Medicare premiums two years from now. Everything else can be tackled in the order that fits your schedule.

What is the biggest retirement money mistake people make in the second half of the year?

Waiting. The most common and costly error is assuming there’s plenty of time and then scrambling in December. Tax moves require lead time — Roth conversions need to settle, charitable donations need documentation, and account changes need processing. Advisors and tax professionals are also swamped in the fourth quarter, making it harder to get timely help. The retirees who finish the year in the best financial shape are almost always the ones who started planning in June.

This checklist is your invitation to be one of those people. Pick one item today — just one — and you’ll have built the momentum to work through the rest over the coming weeks. Your future self will thank you.

Frequently Asked Questions

When should I claim Social Security to maximise my benefit?

Delaying Social Security past your full retirement age (67 for those born in 1960 or later) increases your monthly benefit by about 8% for each year you wait, up to age 70. If you’re in good health and can afford to wait, delaying to 70 gives you the largest possible lifetime benefit. However, if you have health concerns or need income sooner, claiming earlier may still be the right personal choice.

How much of my Social Security benefit is taxable?

Up to 85% of your Social Security benefit can be subject to federal income tax, depending on your combined income (your adjusted gross income, plus nontaxable interest, plus half your Social Security). If that combined figure exceeds $34,000 for single filers or $44,000 for married couples filing jointly, 85% of your benefit is taxable. Managing your other income sources — such as timing IRA withdrawals — can help keep you below these thresholds.

What are the RMD rules for 2025 and 2026?

Under the SECURE 2.0 Act, the age to begin Required Minimum Distributions is 73 for anyone who turns 73 in 2023 or later, rising to 75 for those born in 1960 or after. You must withdraw your RMD from traditional IRAs and most employer retirement plans by December 31 each year (your very first RMD can be delayed to April 1 of the following year, but that means taking two distributions in one year). Missing your RMD triggers a 25% excise tax on the amount not withdrawn.

How do I avoid Medicare IRMAA surcharges?

IRMAA (Income-Related Monthly Adjustment Amount) surcharges are added to your Medicare Part B and Part D premiums when your income from two years prior exceeds set thresholds — starting at $106,000 for single filers in 2026. You can reduce your exposure by managing taxable income: timing large IRA withdrawals, spreading Roth conversions over multiple years, and using Qualified Charitable Distributions instead of taxable withdrawals. If your income dropped due to a life-changing event like retirement or divorce, you can appeal the surcharge using IRS Form SSA-44.

What is the Medicare Part B premium for 2025?

The standard Medicare Part B premium for 2025 is $185.00 per month, up from $174.70 in 2024. Higher-income beneficiaries pay more due to IRMAA surcharges, which can push the monthly premium well above $500 at the highest income tiers. You can find your exact premium amount on your Social Security statement or by logging into your Medicare.gov account.
