If you haven’t reviewed your retirement finances since January, there’s a real chance you’re already $15,000 behind where you should be — not because of bad luck, but because of missed timing on Social Security claims, required minimum distributions (RMDs), and Medicare premium planning. The good news: July is the perfect reset point, and the moves you make in the next 90 days can protect tens of thousands of dollars before 2026 closes out.

Why does the midyear mark matter so much for retirees?

For working Americans, a midyear financial check is helpful. For retirees, it can be the difference between a comfortable year and an expensive one. Several retirement money decisions have hard deadlines or time-sensitive sweet spots clustered in the second half of the calendar year. Missing them doesn’t just cost you this year — it can compound into losses that follow you for a decade or more.

Think about it this way: Social Security timing, RMD withdrawals, and Medicare’s income look-back period all interact with each other. Pull the wrong lever at the wrong time, and you can accidentally trigger higher taxes, steeper Medicare premiums, or a reduced monthly benefit for life. Getting all three right requires a mid-year snapshot — exactly what we’re doing today.

When should I claim Social Security to maximise my benefit?

Claiming Social Security at the right age is one of the highest-value financial decisions you’ll ever make, and it’s worth revisiting even if you’ve already started. If you haven’t claimed yet, here’s the core rule: every year you delay past your full retirement age (currently 67 for most people born after 1960), your monthly benefit grows by 8%. That means waiting from 67 to 70 can permanently increase your check by 24% — for life.

For a retiree whose base benefit is $2,000 a month, that delay is worth roughly $5,760 extra per year, or nearly $115,000 over a 20-year retirement. If you’re still on the fence and you’re in your early 60s, delaying even one year has a measurable payoff. Run your personalised estimate at ssa.gov or ask a financial advisor to model the break-even point based on your health and savings.

If you’ve already claimed, it’s not necessarily final. If you claimed within the last 12 months and regret it, you can withdraw your application (Form SSA-521) and repay what you’ve received — then restart later at a higher amount.

How much of Social Security is taxable?

This surprises a lot of people: up to 85% of your Social Security benefit can be subject to federal income tax, depending on your combined income. The IRS uses a figure called “provisional income” — that’s your adjusted gross income, plus non-taxable interest, plus half your Social Security benefit.

If that number lands between $25,000 and $34,000 for single filers (or $32,000–$44,000 for married couples), up to 50% of your benefit is taxable. Above those thresholds, up to 85% is taxable. The midyear moment matters here because you still have time to manage your income — through Roth conversions, delaying RMDs where allowed, or bunching deductions — before December 31 locks in your tax picture.

What are the RMD rules for 2025 and 2026?

Required minimum distributions — the IRS-mandated withdrawals from your traditional IRA or 401(k) — now begin at age 73 under the SECURE 2.0 Act. If you turned 73 in 2025, you had until April 1, 2026 to take your first RMD. If you pushed it to April, remember: you also owe your 2026 RMD by December 31, 2026. That means two RMDs in one calendar year, which can bump you into a higher tax bracket and trigger IRMAA surcharges on Medicare (more on that below).

For everyone already taking RMDs, now is the time to calculate your 2026 amount based on your December 31, 2025 account balance divided by the IRS life expectancy factor for your age. Many financial institutions calculate this automatically, but don’t assume they’ll remind you in time. Miss your RMD deadline and the penalty is 25% of the amount you should have withdrawn — though it drops to 10% if you correct it quickly.

If you’re charitably inclined, a qualified charitable distribution (QCD) lets you send up to $105,000 directly from your IRA to a qualifying charity in 2026. It counts toward your RMD but doesn’t show up as taxable income — a powerful move if you’re near a tax or Medicare threshold.

How do I avoid Medicare IRMAA surcharges?

IRMAA stands for Income-Related Monthly Adjustment Amount — the extra premium high-income Medicare beneficiaries pay on top of the standard Part B and Part D rates. In 2026, the surcharge kicks in if your 2024 modified adjusted gross income (MAGI) exceeded $106,000 for individuals or $212,000 for couples.

Here’s the catch: Medicare looks back two years. So your 2026 premiums are based on your 2024 income. If you had a one-time income spike in 2024 — a home sale, a large Roth conversion, or two RMDs in one year — you may be paying IRMAA surcharges right now even if your income is lower today. The good news: you can appeal using Form SSA-44 if you’ve had a qualifying life change such as retirement, divorce, or death of a spouse.

For planning purposes, watch your 2026 income carefully, because it will affect your 2028 Medicare premiums. Strategic moves now — like partial Roth conversions spread over multiple years, or timing asset sales — can keep you below the IRMAA thresholds and save hundreds per month.

What is the Medicare Part B premium for 2026?

The standard Medicare Part B premium in 2026 is $185.00 per month for most beneficiaries — up from $174.70 in 2025. That’s a meaningful increase, and it’s automatically deducted from your Social Security payment if you’re already receiving benefits. If you’re subject to IRMAA, your Part B premium can climb to $628.90 or higher per month depending on your income tier. Knowing these numbers lets you accurately budget your net Social Security income and model the real cost of a higher-income year.

Your midyear retirement action checklist

Here’s what to do before August:

  • Calculate your 2026 RMD and decide whether to take it now or near year-end based on your income picture.
  • Check your provisional income to estimate how much of your Social Security will be taxed this year.
  • Review your 2024 MAGI to confirm whether you’re paying IRMAA — and whether you qualify to appeal.
  • Model a Roth conversion to see if moving money now lowers your long-term tax and Medicare costs.
  • Confirm your Social Security strategy — especially if you haven’t claimed yet and you’re between 62 and 69.

The $15,000 gap isn’t a scare tactic. It’s a realistic estimate of what inaction costs across just three or four of these decisions in a single year. The calendar is on your side right now — but that window narrows every week.

Frequently Asked Questions

Frequently Asked Questions

When should I claim Social Security to maximise my benefit?

Delaying Social Security past your full retirement age (67 for most people) increases your monthly benefit by 8% for every year you wait, up to age 70. For many retirees, waiting until 70 results in a 24% larger monthly check for life. The best claiming age depends on your health, other income sources, and whether you’re married — a financial advisor or the SSA’s online calculator can help you find your personal break-even point.

How much of my Social Security benefit is taxable?

Between 0% and 85% of your Social Security benefit may be subject to federal income tax, depending on your provisional income (adjusted gross income plus non-taxable interest plus half your Social Security). Single filers with provisional income above $34,000 and married couples above $44,000 pay tax on up to 85% of their benefit. Managing withdrawals, Roth conversions, and deductions before December 31 can help reduce this taxable portion.

What are the RMD rules for 2025 and 2026?

Under the SECURE 2.0 Act, required minimum distributions now begin at age 73. Your annual RMD is calculated by dividing your prior December 31 account balance by an IRS life expectancy factor. Missing your RMD deadline triggers a 25% penalty on the shortfall, reduced to 10% if corrected promptly. If you turned 73 in 2025 and deferred your first RMD to April 2026, you’ll owe a second RMD by December 31, 2026 — potentially pushing you into a higher tax bracket.

How do I avoid Medicare IRMAA surcharges?

IRMAA surcharges apply when your modified adjusted gross income from two years prior exceeds $106,000 (single) or $212,000 (married). You can reduce exposure by spreading Roth conversions over multiple years, using qualified charitable distributions to satisfy RMDs without raising taxable income, and timing large asset sales carefully. If you experienced a qualifying life event that lowered your income — like retiring or losing a spouse — you can appeal your surcharge using IRS Form SSA-44.

What is the Medicare Part B premium in 2026?

The standard Medicare Part B premium for 2026 is $185.00 per month, up from $174.70 in 2025. This amount is automatically deducted from Social Security payments for most beneficiaries. Higher-income enrollees subject to IRMAA can pay significantly more — up to $628.90 per month — so understanding your income thresholds and planning ahead is essential to accurate retirement budgeting.
