Medicare Part C (Medicare Advantage Plans) is another way to get your Medicare benefits. It combines Part A, Part B, and sometimes Part D (prescription drug) coverage. Medicare Advantage Plans are managed by private insurance companies approved by Medicare. These plans must cover medically-necessary services.

Medicare C is reported on Form 1099-SA Distributions from an HSA, Archer MSA, or Medicare Advantage MSA. The amount included in income is the amount not used to pay medical expenses. Generally, if you receive a taxable distribution, you must also pay an additional tax on the amount included in income. The additional tax for Medicare Advantage MSAs is 50%.

To enter or review information from Form 1099-SA:

1. From within your TaxAct return (Online or Desktop), click Federal. On smaller devices, click in the upper left-hand corner, then click Federal.
2. Click Other Income in the Federal Quick Q&A Topics menu to expand, then click MSA Distributions (Form 1099-SA).
3. Click + Add Form 1099-SA to create a new copy of the form or click Edit to review a form already created.
4. Continue with the interview process to enter all of the appropriate information.

Per the SSA Who can get Medicare? publication, on page 5:

Medicare Advantage plans

If you receive your Part A and Part B benefits directly from the government, you have Original Medicare. If you receive your benefits from a Medicare Advantage organization or other private company approved by Medicare, you have a Medicare Advantage plan. Many of these plans provide extra coverage and may lower your out-of-pocket costs.

If you have Medicare Parts A and B, you can join a Medicare Advantage plan. With these plans, you can’t have a Medigap policy, because Medicare Advantage plans cover many of the same benefits a Medigap policy covers. This includes benefits like extra days in the hospital after you’ve used the days that Medicare covers.

Medicare Advantage plans include all of the following:

• Health Maintenance Organization (HMO) plans.
• Preferred Provider Organization (PPO) plans.
• Private Fee-for-Service (PFFS) plans.
• Special Needs Plans (SNPs).

If you decide to join a Medicare Advantage plan, you use the health card that you get from your Medicare Advantage plan provider for your health care. Also, you might have to pay a monthly premium for your Medicare Advantage plan because of the extra benefits it offers.
