How to Report Your 2023 Medicare Coverage to the IRS

Why the IRS Asks About Your 2023 Medicare

The IRS asks whether you had Medicare at any time in 2023 because it affects how you file your taxes and whether you owe penalties. If you had Medicare Part A or Part B during 2023, you report it on your tax return. The main reason is the Individual Shared Responsibility Payment — a penalty you may owe if you went without may have access to health coverage for more than three months in a row during the year.

Medicare counts as may have access to coverage. So does employer health insurance, marketplace insurance, Medicaid, TRICARE, and several other plans. If you had Medicare for even part of 2023, you had coverage for those months, and you do not owe a penalty for that time period.

You report your coverage status on Form 8965, which attaches to your Form 1040. You do not need to send proof to the IRS — they receive records from Medicare directly — but you do need to answer the question honestly on your return.

Key Takeaways

Medicare Part A or Part B counts as may have access to health coverage for tax purposes, so you report it on Form 8965 if you had it during 2023.
You owe a penalty only if you had a gap of more than three consecutive months without any may have access to coverage during 2023.
The IRS receives Medicare enrollment records directly from Social Security and Medicare, so they already know your coverage dates.
If you had Medicare for the entire year, you check "full-year coverage" on Form 8965 and do not need to list individual months.
If you had Medicare for part of the year and a different plan for another part, you report both and show the months each covered you.

How to Report Medicare Coverage on Your Tax Return

You report your 2023 Medicare coverage using Form 8965: Health Insurance Providers Statement. This form asks you to list each month you had may have access to coverage and which plan covered you. If you had Medicare for the full year, you can straightforward mark "full-year coverage" and move on — you do not need to list each individual month.

If you had Medicare for part of 2023 and a different plan (such as employer insurance or marketplace coverage) for another part, you list both. For example, if you turned 65 in July and enrolled in Medicare Part A and Part B, you would show employer coverage for January through June and Medicare for July through December.

Form 8965 attaches to your Form 1040 when you file. You file it with your tax return, not separately. If you use tax software or work with a tax preparer, they will ask you about your coverage and fill in the form for you.

When You Had Medicare for Only Part of 2023

If you enrolled in Medicare partway through 2023 — for example, when you turned 65 or after a may have access to life event — you report the months you had Medicare and the months you had other coverage. The IRS needs to see that you had may have access to coverage for each month, or that any gap was three months or less.

A common scenario is someone who retired mid-year. If you had employer coverage through June and Medicare starting in July, you had coverage for all 12 months and owe no penalty. If you had employer coverage through June, nothing in July and August, and Medicare starting in September, you had a two-month gap — still under the three-month threshold, so no penalty.

If you had employer coverage through June and did not enroll in Medicare until October, you had a three-month gap (July, August, September). A gap of exactly three months does not trigger a penalty. A gap of four months or more does.

What Happens If You Did Not Have Medicare or Other Coverage

If you had no may have access to health coverage for more than three consecutive months during 2023, you owe the Individual Shared Responsibility Payment. The amount is the greater of two calculations: either a percentage of your household income or a flat dollar amount per person. The exact dollar amount varies by year and by the number of people in your household without coverage.

You calculate the penalty on Form 8965 itself. The form walks you through the math: it asks how many months you were uninsured, subtracts any months you had coverage, and then applies the penalty formula. You then add the penalty to the tax you owe when you file.

There are limited exceptions to the penalty — for example, if you had a hardship such as homelessness, eviction, or a utility shutoff. If you believe you had a hardship, you can claim an exemption on Form 8965 by checking the relevant box and attaching a brief explanation.

The IRS Already Has Your Medicare Records

Social Security and Medicare send enrollment records to the IRS automatically. This means the IRS already knows whether you had Medicare in 2023, when you enrolled, and when you disenrolled if you did. You do not need to send proof or documentation with your tax return.

However, you still must report your coverage on Form 8965. The IRS uses your report to cross-check against the records they received. If your report does not match the records, the IRS may contact you to clarify. If you made a mistake, it is easier to correct it on your return than to deal with a notice later.

If you had Medicare but did not report it on your return, or if you reported different dates than what Medicare has on file, the IRS will send you a notice asking you to explain the discrepancy. You can then provide the correct information and avoid a penalty.

Medicare Part A Versus Part B: What Counts

Both Medicare Part A (hospital insurance) and Medicare Part B (medical insurance) count as may have access to coverage for tax purposes. You do not need both — having either one is enough. Most people age 65 and older have both, but some have only Part A or only Part B depending on their work history and enrollment choices.

Medicare Part D (prescription drug coverage) and Part C (Medicare Advantage) do not count as may have access to coverage on their own. However, if you have Part C (Medicare Advantage), you automatically have Part A and Part B coverage through that plan, so you still have may have access to coverage.

If you had Part A or Part B for any month in 2023, report that month as covered. If you had a gap between when one coverage ended and another began, count those days carefully — a gap of three months or fewer does not trigger a penalty.

Common Mistakes When Reporting Medicare Coverage

The most common mistake is not reporting Medicare coverage at all. Some people assume that because the IRS already has the records, they do not need to report it themselves. This is wrong — you must report it on Form 8965, even if the IRS already knows about it.

Another mistake is reporting the wrong enrollment date. If you enrolled in Medicare in July, do not report June as covered. The IRS will see the discrepancy when they compare your return to the records from Medicare. If you are unsure of your exact enrollment date, check your Medicare card or log into your Medicare account online.

A third mistake is forgetting to report a gap in coverage. If you had employer insurance through one month and Medicare starting the next month, that is not a gap — you had coverage for both months. But if there was a month in between when you had nothing, you must count it and report it honestly on Form 8965.

I had Medicare Part A but not Part B in 2023. Do I still report it?
