Medigap Household Discount: Save 5-14% on Your Premiums

What Is the Medigap Household Discount?

The Medigap household discount is a premium reduction that most major Medicare Supplement carriers offer when two eligible adults live at the same address. It's one of the few discounts on Medigap policies that can meaningfully reduce your monthly cost, and it typically ranges from 5% to 14% off the base premium.

Because Medigap benefits are federally standardized (a Plan G from one carrier covers the same things as a Plan G from another), premiums and discounts are where carriers actually compete. The household discount is filed with each state's insurance department, so the exact percentage and eligibility rules can vary by carrier, plan, and ZIP code.

Unlike Medicare Advantage, where the government sets many rules, Medigap premium pricing structures are largely a private carrier decision. That's why shopping matters so much, and why a discount buried in fine print can be the difference between two otherwise identical quotes.

Which Carriers Offer a Household Discount in 2026?

Almost every top-rated Medigap carrier offers some form of household discount, but the size varies significantly. Here's how the major national carriers stack up for 2026.

If you want carrier-specific detail, our full Mutual of Omaha Medicare Supplement review and Cigna Medicare Supplement review walk through how each company applies the discount alongside base rates.

Why Mutual of Omaha stands out

Mutual of Omaha's 12% household discount is one of the most generous in the industry, and its rules are relatively flexible. In most states, you qualify if you've lived with another adult for the past year, and the other person doesn't necessarily need to hold a Mutual of Omaha Medigap policy.

Do You Have to Be Married?

This is the single biggest misconception about the Medigap household discount. In many cases, no, you don't have to be married.

Carriers use different definitions of "household," and the rules generally fall into three buckets:

1. Marriage or legal partnership required

Some carriers (Aetna is a common example) require the two applicants to be spouses, civil union partners, or registered domestic partners. In these cases, both people typically must be Medicare-eligible and enroll with the same underwriting company in the same state.

2. Any adult co-resident with age or duration rules

Many carriers will grant the discount if you've lived with another qualifying adult (often age 50, 60, or Medicare-eligible) for at least 12 continuous months. The other person can be:

• A sibling
• An adult child
• A roommate
• A significant other or domestic partner
• Any long-term co-resident meeting age rules

3. Any adult in the household, no relationship required

A few carriers, and some Blue Cross Blue Shield state plans, apply the discount simply because you and another Medigap policyholder live at the same single-family home, condo, or apartment. You don't have to be related at all.

Do Both People Need the Same Carrier?

Usually yes, but not always. Here's how it typically works:

Even when the same-carrier rule applies, you and your spouse do not need to pick the same plan letter. One of you can enroll in Plan G while the other picks Plan N, and both policies still receive the household discount. That flexibility matters if one of you wants richer coverage and the other prefers lower premiums.

How the Household Discount Stacks With Other Savings

The household discount is often just the starting point. Most carriers allow it to combine with several other discounts, which is where the real savings show up.

Common stackable discounts include:

• Electronic funds transfer (EFT) / autopay, usually $2 to $3 per month
• Annual or semiannual pay discount, small percentage off for paying in bulk
• Non-tobacco rate, standard preferred pricing for non-smokers
• Online enrollment discount, Humana offers 6% (excluded in CA, CT, OH, PA)
• New-to-Medicare discount, a few states offer a first-year discount
• Multi-year membership discount, AARP/UnitedHealthcare offers 8% to 21% multi-year reductions

At its best, a HealthSpring (Cigna) policyholder in a state that allows both the household and online discounts can stack them for savings approaching 25%. On a $165 base premium, that's roughly $40 per month, or nearly $500 per year, per person.

State-by-State Variations

There is no federal rule requiring carriers to offer a household discount, and no federal rule banning it either. Every discount is a carrier filing approved by the state, which means availability varies in three ways:

1. Which carriers sell in your state. Mutual of Omaha doesn't sell Medigap in Massachusetts, for example, so its 12% household discount isn't an option there.
2. How the carrier defined the discount in that state's filing. The same carrier might use different residency or age rules in different states.
3. How state-specific rules interact. Massachusetts, Minnesota, and Wisconsin use standardized plan structures that differ from the other 47 states, which can affect discount availability.

Common state exclusions

• Humana's 6% online enrollment discount (which stacks with household savings) is not available in California, Connecticut, Ohio, or Pennsylvania.
• Some carriers require Medicare eligibility for both parties in certain states, which changes eligibility for cohabitating adults under 65.
• A few community-rated states like New York already price Medigap uniformly, which can reduce the size of some carrier discounts.

The bottom line: always confirm the specific discount rules in your state before assuming a national average applies.

How Much Can a Household Discount Actually Save You?

Let's put real numbers to it. The 2026 national average Plan G premium at age 65 is about $165.85 per month. Here's what household discounts of different sizes would save a couple.

At age 75, where the national Plan G average rises to about $205 per month, a 12% household discount saves a couple roughly $590 per year. Over 10 years of coverage, that's nearly $6,000 in household savings, and that's before adding autopay or annual-pay discounts on top.

Using the Discount as a Tiebreaker

When you're comparing quotes from similarly priced carriers, the household discount can shift the winner. Here's a practical approach:

1. Get quotes from at least three carriers using your ZIP code, ages, and tobacco status.
2. Ask each carrier or broker for the net premium after household discount, not just the base rate.
3. Confirm the discount's residency requirements and same-carrier rules apply to your situation.
4. Factor in how likely the discount is to remain in place (e.g., if a roommate might move out).
5. Check whether other discounts (autopay, annual pay) stack on top.

For couples specifically, remember that you don't have to pick identical plans. One spouse can enroll in the AARP/UnitedHealthcare Plan G while the other picks a different plan letter, and both still qualify for the household discount if the carrier allows different plans under the same policyholder rules. Just be sure to verify same-carrier eligibility before assuming both discounts will apply.

Also consider the carrier's rate stability. A 12% household discount is less valuable if the carrier files 20% rate increases every year. Our review of Humana's Medicare Supplement plans explains why rate history matters as much as the initial discount.

Frequently Asked Questions

Do I have to be married to get a Medigap household discount?

No, not with most carriers. Many companies extend the discount to any two adults living at the same address, though some require age thresholds (often 50 or 60) or a minimum co-residency period of 12 months. Aetna is one common exception, as it typically requires a spouse, civil union partner, or domestic partner in most states.

What happens to my discount if my spouse or roommate moves out?

The household discount will end and your premium will increase to the standard rate. You are typically required to notify your carrier of the change in living situation. Some carriers may allow you to reapply if a new qualifying adult moves in, but the transition usually isn't automatic.

Can I get a household discount if my spouse isn't on Medicare yet?

It depends on the carrier. Some, like Mutual of Omaha in many states, extend the discount as long as you live with another adult meeting age criteria, regardless of Medicare enrollment. Others require both people to be Medicare-eligible and hold Medigap policies with the same company.

Do both spouses need the same Medigap plan letter?

No. You and your spouse can pick different plan letters (for example, Plan G and Plan N) from the same carrier and still receive the household discount on both policies. This flexibility helps couples balance coverage needs with premium budgets.

Can I stack the household discount with other savings?

Usually yes. Most carriers allow the household discount to combine with autopay/EFT, annual-pay, non-tobacco, and online enrollment discounts. Total stacked savings can reach 20% to 25% with some carriers like HealthSpring (Cigna), though a few insurers restrict certain combinations, so always confirm with your carrier or broker before enrolling.
