Retirement Income & Medicare Costs in 2026: Grand Junction
The check you cash this year sets your Medicare premium two years from now — and the income events people most often want undone are the ones Social Security won't reconsider.
The bottom line
- Your premium runs on a two-year delay. Social Security uses the most recent return the IRS can give it — generally two years back — so your 2026 Medicare premium is generally set by your 2024 tax return (SSA POMS HI 01101.010).
- MAGI is broader than "taxable income." It's your adjusted gross income plus tax-exempt interest — so municipal bond interest counts too.
- It's a cliff, not a ramp. One dollar past $109,000 single / $218,000 joint puts you in the next tier for the whole year — roughly $1,148 more per person, and every figure applies twice for a couple.
- The events people want undone usually can't be. Social Security's own manual lists capital gains from a property sale and an IRA-to-Roth conversion as non-qualifying events (SSA POMS HI 01120.005). Retiring or cutting back hours does qualify — that's what form SSA-44 is for.
- Time the big income year on purpose, with your tax advisor. We'll handle the Medicare side — free, local, no pressure.
Most people meet IRMAA by mail. A letter arrives from Social Security, the Part B premium has jumped by a few hundred dollars a month, and the income year that caused it is already two tax seasons in the rearview. Nothing went wrong — the system is working exactly as designed. But it's a system you can plan around, and the planning has to happen before the income lands, not after the letter does.

Here's something that catches a lot of Grand Junction retirees off guard: a big income year today can raise your Medicare premium two years from now. Social Security looks at your modified adjusted gross income — your adjusted gross income plus tax-exempt interest — and it generally pulls that from a tax return two years back. So your 2026 premium is generally based on your 2024 return. In 2026, the first threshold is one hundred nine thousand dollars if you file single, two hundred eighteen thousand if you file jointly. Cross it by one dollar and you're in the next tier for the entire year — about eleven hundred forty-eight dollars more per person. Now here's the part almost nobody knows. Social Security will redo your premium after a real life change: you retired, you cut back your hours, you lost a pension, you lost a spouse. But its own manual says capital gains from selling property and converting an IRA to a Roth are non-qualifying events. Meaning: the one-time income spike you chose usually can't be appealed. So sell the ground, convert the IRA, take the distribution — just do it with the Medicare bill two years out in the picture, and talk to your tax advisor first. We're happy to walk through the Medicare side, free. Call Medicare on Main in Grand Junction at 970-644-6954.
What income does Medicare actually count?
Not "taxable income," and not your Social Security check. Social Security's own operating manual defines the measure precisely: modified adjusted gross income (MAGI) is your adjusted gross income — line 11 of Form 1040 — plus tax-exempt interest from line 2a. That second piece catches people. Municipal bond interest is federally tax-free, but it is added back here on purpose, so a portfolio built partly around munis doesn't sidestep the calculation.
Everything that lands in AGI counts, including:
- Traditional IRA and 401(k) withdrawals, including required minimum distributions once they begin.
- The taxable portion of a Roth conversion — the conversion year is the expensive year.
- Capital gains on the sale of land, a rental, a second home, or a business.
- Dividends, interest, rents, and royalties — including oil, gas, and mineral royalties.
- The taxable share of Social Security benefits, plus pension and annuity income as it's reported on your return.
What generally doesn't show up in AGI: qualified withdrawals from a Roth IRA, and the return of your own basis. That asymmetry — the conversion is counted, the later withdrawal isn't — is the whole reason conversion timing is worth thinking about.
Why is my premium based on a two-year-old tax return?
Because Social Security uses the most recent return the IRS can hand it. Per POMS HI 01101.010, "generally, the information is from two years prior to the year for which the premium is being determined" — so 2026 premiums are generally based on 2024 tax return information. Occasionally the agency only has a three-year-old return to work from.
Two practical consequences fall out of that delay:
- The year you retire is not the year your premium drops. Your first year or two on Medicare can be priced off your final high-earning working years. This is the one situation the appeal process was built for — see below.
- A one-time windfall has a two-year fuse. Sell the ground in 2026 and the Medicare consequence shows up in your 2028 premium, long after the money has been spent or reinvested. Budget for it now, not then.
What are the 2026 brackets — and how big is the cliff?
These are the 2026 figures released by CMS on November 14, 2025. The Part B column is your total monthly premium at that tier; the Part D column is a surcharge added on top of whatever your drug plan charges:
| 2024 MAGI — individual | 2024 MAGI — joint | 2026 Part B/mo | Part D surcharge/mo | |
|---|---|---|---|---|
| Up to $109,000 | Up to $218,000 | $202.90 | $0.00 | Standard |
| $109,001 – $137,000 | $218,001 – $274,000 | $284.10 | $14.50 | Tier 1 |
| $137,001 – $171,000 | $274,001 – $342,000 | $405.80 | $37.50 | Tier 2 |
| $171,001 – $205,000 | $342,001 – $410,000 | $527.50 | $60.40 | Tier 3 |
| $205,001 – under $500,000 | $410,001 – under $750,000 | $649.20 | $83.30 | Tier 4 |
| $500,000 and above | $750,000 and above | $689.90 | $91.00 | Tier 5 |
Source: CMS: 2026 Medicare Parts A & B Premiums and Deductibles (Nov 14, 2025). Figures shown are for beneficiaries with full Part B coverage; separate tables apply to immunosuppressive-drug-only coverage and to married beneficiaries who lived together but filed separately.
Now the part that changes behavior. IRMAA is a cliff: there's no phase-in, so a single dollar over a threshold moves you into the next tier for the entire year. Here's what each step actually costs, per person:
The two annual figures are simple arithmetic on the CMS monthly amounts above (12 × the combined Part B and Part D adjustment), shown to make the size of each step concrete.
Which means the last few thousand dollars of a distribution can be the most expensive money you take all year. If your projected MAGI is going to land near a threshold, that's the moment to call your tax advisor and ask whether some of the income can shift into the next tax year.

Map my Medicare costs →What will Social Security reconsider — and what won't it?
This is where the surprise lives. Social Security will redo your determination after a qualifying life-changing event, and its manual is blunt that the list is exclusive — "our list of LCEs for IRMAA purposes is exclusive." Eight events qualify. Several very common income spikes explicitly do not:
| Event | Can Social Security redo your IRMAA? |
|---|---|
| You stopped working or retired | Qualifying |
| You cut back your hours or work | Qualifying |
| Death of a spouse | Qualifying |
| Marriage, divorce, or annulment | Qualifying |
| Loss of income-producing property (outside your control) | Qualifying |
| Loss of an employer pension | Qualifying |
| Settlement payment from a current or former employer | Qualifying |
| Capital gains from selling property or a business | Non-qualifying |
| Converting a traditional IRA to a Roth | Non-qualifying |
| Cashing in bonds, or lottery and casino winnings | Non-qualifying |
| Higher medical or living expenses | Non-qualifying |
Source: SSA POMS HI 01120.005 — Life Changing Events, which lists the eight qualifying events and names capital gains from the sale of property, conversion of an IRA, cashing bonds, and lottery or casino winnings as non-qualifying.
Read that table twice if you're weighing a conversion or a sale. The logic behind it is consistent even if it stings: the appeal exists for people whose income genuinely dropped for a reason outside a normal financial decision — you retired, your hours were cut, a spouse died, a pension failed. It does not exist to undo a profitable year you chose to have.
If you do have a qualifying event, don't wait for the letter to feel final. File form SSA-44 with proof of the event and an estimate of the more recent year's income. People most often qualify simply by retiring — a work stoppage is a life-changing event, and it's the single most common successful IRMAA appeal we see.
How do you sequence a big income year?
There's no universal answer, and the right one depends on tax brackets, charitable intent, estate goals, and how long the money needs to last — all of which belong with your tax advisor and financial professional. What we can do is name the Medicare-side questions worth putting in front of them:
- Where will this year's MAGI land relative to the nearest threshold? Project it before December, not in April.
- Can the income be split across two tax years? Two smaller conversions, or an installment structure on a sale, may keep both years under a cliff — or may not be worth the complexity. It's a math question.
- Is the surcharge a one-year event or a permanent step up? A one-time sale usually washes out the following year; a permanently higher RMD schedule doesn't.
- Which years are "quiet"? The window between retiring and starting RMDs is where many retirees have the most control over MAGI.
- Does a guaranteed-income arrangement change the shape of the income? Annuities and similar income products are not Medicare coverage and don't change what Medicare pays — but how and when income is recognized can matter to MAGI. Features, costs, and suitability vary a great deal, so review any such option with a licensed professional and take the tax treatment to your tax advisor. Nothing here is a recommendation of any product.
One more piece of the cost picture while you're modeling: in 2026 every Part D enrollee's out-of-pocket spending on covered drugs stops at $2,100 for the year, and the standard Part B deductible is $283. Those are fixed regardless of income — it's the premium side that moves.
Why does this land hard in Mesa County?
Grand Junction retirement money often isn't a tidy monthly pension. It's Palisade orchard ground and Redlands acreage that appreciated for thirty years, a contracting or medical practice sold at retirement, mineral and royalty interests, rental property built up over a career on the Western Slope. Those are lumpy, one-time income events — precisely the kind that spike a single year's MAGI and precisely the kind Social Security's manual calls non-qualifying.
The other half of the picture is health, because premium is only one line of your Medicare cost. Here's what Mesa County adults are actually managing, per CDC PLACES:

If you manage any of those, the drug formulary and specialist network on your plan will move your yearly total more than a tier of IRMAA will. Both are worth getting right — and you can compare every plan offered in Mesa County on medicare.gov/plan-compare.
How we know all this: the Medicare On Main Data Desk frames every article with public data — here, the 2026 income-related premium tables from CMS.gov (November 14, 2025), the MAGI definition and two-year lookback from SSA POMS HI 01101.010, the qualifying and non-qualifying event lists from SSA POMS HI 01120.005, and Mesa County health figures from CDC PLACES (2023) — and qualitative language for anything that varies by household.

Frequently asked questions
What income does Medicare use to set my 2026 premium?
Social Security uses your modified adjusted gross income (MAGI), which its own manual defines as your adjusted gross income (line 11 of Form 1040) plus tax-exempt interest (line 2a). Per SSA POMS HI 01101.010, the figure normally comes from the most recent return the IRS can provide — generally two years back, so 2026 premiums are generally based on your 2024 return. Anything that lands in AGI counts: IRA and 401(k) withdrawals, required minimum distributions, the taxable portion of a Roth conversion, capital gains on a property or business sale, dividends, rents, royalties, and the taxable share of Social Security. Municipal bond interest doesn't escape it either — tax-exempt interest is added back on purpose.
Does a Roth conversion raise my Medicare premiums?
It can. The taxable amount of a Roth conversion flows into your AGI for that year, and that year's MAGI is what Social Security uses two years later to decide whether an IRMAA surcharge applies. In 2026 the first threshold is $109,000 for individual filers and $218,000 for joint filers (CMS). The conversion may still be the right long-term move — it can reduce future required minimum distributions and future MAGI — but the Medicare cost of the conversion year deserves to be part of the math. Run the sizing with your tax advisor before you convert.
Can I appeal an IRMAA surcharge caused by selling property or converting an IRA?
Generally no, and this is the detail that surprises people most. Social Security's list of qualifying life-changing events is exclusive — eight events, including work stoppage, work reduction, marriage, divorce, death of a spouse, loss of income-producing property, loss of an employer pension, and an employer settlement payment (SSA POMS HI 01120.005). The same manual names capital gains from the sale of property and conversion of an IRA as examples of NON-qualifying events. So a one-time income spike you chose is usually not appealable; a genuine drop in income caused by one of the eight events is. If you retire or cut back your hours, that's exactly what form SSA-44 is for.
How much does crossing an IRMAA threshold actually cost in 2026?
IRMAA is a cliff, not a ramp — one dollar over a threshold moves you into the next tier for the whole year. Using the 2026 CMS figures: crossing the first threshold adds $81.20 a month to Part B and $14.50 a month to Part D, about $1,148 more per person for the year. At the top tier the Part B premium is $689.90 a month instead of $202.90, plus $91.00 a month on Part D. For a married couple both on Medicare, every figure applies twice.
Are annuities or other retirement-income products part of my Medicare planning?
They're separate products — an annuity is not Medicare coverage, and nothing about one changes what Medicare pays. Where they intersect is income: money that comes out of a non-qualified or qualified income stream in a given year can land in AGI and therefore in the MAGI that sets your Medicare premium two years later. Some retirees care about smoothing income across years for exactly that reason; others don't. Product features, costs, and suitability vary widely, so review options with a licensed professional and take the tax question — including how any income stream is taxed — to your tax advisor. This article is education, not a recommendation.
