Working Past 65 in Monticello, UT: Medicare in 2026
In San Juan County the answer splits two ways: the school, the hospital, and county offices are big enough to let you wait — but the ranch, the shop, and the trades usually aren't. Here's how to tell which side you're on.
The bottom line
- Still working at 65 with coverage from a 20+ employee employer (yours or your spouse's)? You can usually delay Part B penalty-free — the group plan pays first.
- If the employer has fewer than 20 employees — most private jobs across San Juan County — Medicare pays first at 65, and skipping Part B can leave bills the group plan won't cover.
- HSA savers: your contribution limit drops to zero the month Medicare starts — and Part A can be backdated up to 6 months if you enroll after 65 (IRS Pub. 969).
- COBRA does not count as current-employment coverage. Your 8-month Part B window starts when employment or the group plan ends — not when COBRA does.
- Miss the window and the Part B penalty is 10% per full year, for life — about $20.29/month per year of delay at the 2026 base premium of $202.90.
If you're turning 65 in Monticello and still working, you may not need all of Medicare yet — but whether you can safely wait comes down to your employer's size, not your preference. With coverage from a 20-or-more-employee workplace, you can usually delay Part B without penalty. With a smaller employer, Medicare becomes your primary coverage at 65 whether you enroll or not, and that makes enrolling on time the safe move. What makes San Juan County unusual is that both worlds sit side by side — so let's sort out which one you're in, rule by rule, with the official sources.

Hi, it's Emma with Medicare on Main. If you're still working at 65 in Monticello or anywhere in San Juan County, whether you can delay Medicare comes down to one thing: your employer's size. If your employer, or your spouse's, has twenty or more employees — like the school district, the hospital, or county offices — you can usually delay Part B with no penalty. But if it's a smaller shop, ranch, or trade with fewer than twenty employees, Medicare pays first the month you turn 65, even if you never sign up. So skipping Part B can leave you with the bills. Two quick traps to know: COBRA does not count as current employer coverage, and your HSA contributions have to stop once Medicare starts. Miss your eight-month enrollment window and the Part B penalty is ten percent a year — for life. Not sure which side of the line you're on? Call Medicare on Main, right here in Monticello, at 435-260-3200.
What is the 20-employee rule?
Medicare decides who pays your medical bills first — Medicare or your job-based plan — using coordination of benefits, and the biggest factor is employer size. Per Medicare.gov's "Who pays first?" rules:
| Your situation at 65 | Who pays first | Your move | |
|---|---|---|---|
| Employer has 20+ employees (you or your spouse actively working) | Employer plan pays first; Medicare (if you have it) pays second | You can usually delay Part B penalty-free while the coverage lasts. Compare costs — sometimes Medicare still wins. | Can delay |
| Employer has fewer than 20 employees | Medicare pays first at 65; the group plan may pay only secondary | Enroll in Part A AND Part B on time. Without Part B, the plan may not pay what Medicare would have covered. | Enroll now |
| COBRA or retiree coverage | Medicare pays first; COBRA/retiree plans pay second | This is NOT current-employment coverage — it doesn't delay your Part B deadline or prevent penalties. | No protection |
| No employer coverage | Medicare is your primary coverage | Use your 7-month Initial Enrollment Period around 65 — waiting invites lifelong penalties. | Enroll now |

Two details people miss: the coverage must be based on current, active employment (yours or your spouse's), and the 20-employee test is about the employer's total headcount — not how many people are on the plan.
Why does San Juan County split two ways?
Most rural counties lean one direction — either everyone works for a big employer or almost no one does. San Juan County is different, and that's exactly why this decision trips people up here. On one side sit the county's large public employers: the San Juan School District, San Juan Hospital, county and municipal government, and tribal government offices generally clear 20 employees. If your coverage (or a spouse's) comes from one of those, you can usually delay Part B penalty-free while you keep working.
On the other side is nearly everything else — the ranches, dry-farm operations, trades, outfitters, and Main Street businesses of Monticello, Blanding, Bluff, and the surrounding communities. These are almost all under 20 employees, and there the rule flips: Medicare pays first the month you turn 65, even if you never enroll. The group plan is only expected to pay second. So if you skip Part B, there can be a hole exactly where Medicare's share was supposed to be — Medicare.gov warns that small-employer coverage "might not pay for health services if you don't have both Part A and Part B."
Health is the other reason not to leave gaps. San Juan County carries the heaviest chronic-condition load in our service area — per CDC PLACES (2023), 34.6% of adults live with high blood pressure and 13.7% with diagnosed diabetes — the kind of ongoing care where a primary-payer gap gets expensive fast. When you're not sure which side of the 20-employee line your job falls on, the safe default is to enroll on time and sort out the coordination afterward.

Check my timing →How does Medicare affect my HSA?
If you fund a Health Savings Account through a high-deductible work plan, Medicare changes the math. Per IRS Publication 969, beginning the first month you're enrolled in any part of Medicare, your HSA contribution limit is zero. Even premium-free Part A ends your eligibility to contribute.
The trap is retroactivity: if you enroll in Medicare after 65, Part A coverage can be backdated up to 6 months — and the IRS applies the zero-contribution rule to those retroactive months too. Contributions made during backdated coverage count as excess contributions and carry tax consequences. The rhythm most people follow: plan to stop HSA contributions about 6 months before applying for Medicare or Social Security benefits, and confirm the exact timing with your tax professional.
Money already in the HSA stays yours — you can spend it tax-free on qualified medical costs, including Medicare premiums, for the rest of your life. The rule only stops new contributions.
Does COBRA protect me from the penalty?
No — and this myth is expensive. Medicare.gov is explicit: COBRA is not coverage based on current employment. Electing 18 months of COBRA at retirement does not pause your Part B clock — your 8-month Special Enrollment Period starts when your employment or your group coverage ends, whichever comes first. Ride COBRA past that window and you're facing the lifelong penalty plus a wait for the next General Enrollment Period. Retiree coverage works the same way: welcome extra protection, but no substitute for enrolling on time.
What happens if I miss my 8-month window?
When you (or your spouse) stop working or the group coverage ends, you get an 8-month Special Enrollment Period to take Part B penalty-free (Medicare.gov — When can I sign up for Medicare?). Miss it, and the Part B late penalty adds 10% of the standard premium for each full 12-month period you went without Part B or creditable employer coverage — and you pay it for as long as you have Part B.

What should I do if I'm working past 65 in 2026?
- Ask HR one question first: does the employer have 20 or more employees? That answer sets your whole strategy.
- 20+ employees (school district, hospital, county or tribal government): you may delay Part B penalty-free — but compare anyway. Sometimes Part B plus a Medigap or Advantage plan costs less than your payroll deduction.
- Fewer than 20 (most ranches, shops, and trades): enroll in Part A and Part B on time during your Initial Enrollment Period. Medicare is primary at 65 whether you sign up or not.
- Funding an HSA? Map your last contribution about 6 months before you apply for Medicare, and confirm with your tax pro.
- When work ends, calendar your 8-month Part B window immediately — and don't let COBRA lull you past it.

Frequently asked questions
Do I have to sign up for Medicare at 65 if I'm still working in San Juan County?
It depends on how many people your employer has. If you (or your spouse) are actively working and the employer has 20 or more employees — think the San Juan School District, San Juan Hospital, or county and tribal government offices — that group plan pays first and you can usually delay Part B without a penalty. If the employer has fewer than 20 employees — most ranches, trades, outfitters, and Main Street shops in the Monticello area — Medicare pays first at 65, and skipping Part B can leave you exposed. The official rules are on Medicare.gov's “Working past 65” page.
My Monticello employer has fewer than 20 employees. What should I do at 65?
Enroll in both Part A and Part B during your Initial Enrollment Period. With a small employer, Medicare becomes the primary payer at 65, and your job-based plan may only pay secondary — meaning if you skip Part B, you could owe the share Medicare would have paid. In a county where most private employers are small family operations, this is the single most common trap we see.
Can I keep contributing to my HSA after 65?
Only if you are NOT enrolled in any part of Medicare — including premium-free Part A. Per IRS Publication 969, your HSA contribution limit drops to zero beginning the first month you're enrolled in Medicare, and the rule applies to retroactive coverage too. If you enroll after 65, Part A can be backdated up to 6 months, so the common guidance is to stop HSA contributions about 6 months before you apply, then confirm the timing with your tax professional.
Does COBRA count as employer coverage so I can delay Part B?
No — and this is one of the most expensive Medicare mistakes. COBRA is not coverage based on current employment, so it does not protect you from the Part B late penalty and does not give you a Special Enrollment Period when it ends. If you're 65+ and lose job-based coverage, your 8-month window to enroll in Part B starts when the employment or the group coverage ends — whichever comes first — not when COBRA runs out.
How long do I have to enroll in Part B after I stop working?
You have an 8-month Special Enrollment Period that starts the month after your employment ends or your group coverage ends, whichever happens first. Enroll inside that window and you pay no penalty. Miss it, and you may have to wait for the General Enrollment Period and pay a lifelong Part B penalty of 10% for each full 12-month period you went without coverage.
Does Medicare On Main charge to help me sort this out?
No. Brian Penner is an independent, licensed Medicare advisor with 22+ years of experience — paid by the carriers, not by you. Walking through your employer's size, your HSA, and your enrollment deadlines is free and no-pressure, from our office at 65 S Main St in Monticello.
