No, they are not the same, and the differences matter for your taxes and how you use the money

A Medical Savings Account (MSA) and a Health Savings Account (HSA) are separate accounts with different rules, different tax treatment, and different may be able to access requirements. Both let you set aside pre-tax money for medical expenses, but an MSA is older, less common, and has stricter limits on how much you can contribute and what insurance plan you need to own. An HSA is newer, more flexible, and available to more people. If someone mentions "medical savings account" to you, they might mean an MSA, or they might be using the term loosely to describe an HSA. The only way to know is to ask what plan it is tied to and what the contribution limits are.

The practical difference comes down to portability and reach. An MSA stays locked to your insurance plan and has income caps that disqualify most middle-income earners. An HSA follows you from job to job, has no income limits, and is offered by the vast majority of employers and insurers. If your employer or insurance company offers a medical savings account, it is almost certainly an HSA.

Key Takeaways

  • MSAs are older accounts tied to high-deductible health plans with specific income caps and contribution limits that have not changed since 1996, while HSAs are newer and have higher contribution limits that adjust yearly.
  • MSAs require you to have a high-deductible plan and meet strict income thresholds; HSAs require only a high-deductible plan and have no income limit.
  • Money in an MSA can roll over year to year, but you lose contribution rights if you change insurance plans; HSA money stays with you even if you change plans or leave your job.
  • Both accounts let you withdraw money tax-free for may have access to medical expenses, but HSAs are far more widely offered by employers and insurance companies.
  • If your employer or insurance company offers an account, that is almost certainly an HSA—MSAs are rare and usually only available through individual insurance policies.

How MSAs and HSAs differ in may be able to access and contribution limits

To open an MSA, you must have a high-deductible health plan and meet income limits set by the IRS. Those income thresholds have not changed since 1996, which means they are now so low that most people earning a middle-class income exceed them. For 2024, the MSA income cap is roughly $36,000 for self-employed individuals and $75,000 for employees—well below the median household income in most states. If you earn above those limits, you cannot open an MSA, period.

HSAs have no income limit. You only need to be enrolled in a high-deductible health plan. The contribution limits are also much higher: for 2024, you can contribute up to $4,150 per year for self-only coverage or $8,300 for family coverage. Those limits increase slightly each year. MSAs cap out at roughly half that amount and have not budged since the 1990s.

Both accounts require you to have a high-deductible plan, meaning your deductible is at least $1,600 (self-only) or $3,200 (family) for 2024. But the MSA rules are stricter: your out-of-pocket maximum cannot exceed certain thresholds, and your plan must meet specific design requirements that most insurers stopped offering years ago.

What happens to your money if you change plans or leave your job

An MSA is tied to your insurance plan. If you switch to a different high-deductible plan, you can keep the money in your old MSA, but you cannot add new contributions to it. If you drop your high-deductible coverage altogether—because you switch to a regular plan, lose your job, or retire—you can still withdraw money from the MSA for medical expenses, but only if you remain uninsured or stay on a high-deductible plan. The rules are complicated and the penalties for breaking them are steep.

An HSA is yours to keep. You own it, not your employer or your insurance company. If you change jobs, change insurance plans, or retire, the money stays in your HSA and you can use it for medical expenses whenever you want. You can even invest the money in stocks or bonds inside the account, just like a retirement account. This portability is one of the biggest practical differences between the two. Your HSA follows you for life, regardless of what happens to your insurance or employment.

Tax treatment and withdrawal rules

Both MSAs and HSAs let you contribute money before taxes are taken out of your paycheck, which lowers your taxable income for the year. Both let you withdraw money tax-free as long as you use it for may have access to medical expenses—doctor visits, prescriptions, dental work, vision care, and many other health-related costs.

The key difference is what happens if you withdraw money for something that is not a may have access to medical expense. With an HSA, you pay income tax on the withdrawal plus a 20 percent penalty if you are under 65. With an MSA, the penalty is 20 percent as well, but the tax rules are stricter about what counts as a may have access to expense. After age 65, both accounts let you withdraw money for any reason without penalty, though you still pay income tax on non-medical withdrawals from an MSA.

MSAs also have a "use it or lose it" rule in some cases: if you do not spend the money within a certain timeframe or if you change insurance plans, you may forfeit unused funds. HSAs do not have this rule—money rolls over indefinitely and is yours to keep. This is another reason HSAs are more practical for most people: you do not have to worry about losing money you have saved.

Why HSAs are far more common than MSAs

MSAs were created in 1996 as a pilot program for self-employed people and small business employees. They were supposed to be temporary, but they were never shut down. However, insurers and employers largely stopped offering them because the income caps and contribution limits made them impractical for most workers. Today, MSAs are rare—you are unlikely to encounter one unless you buy an individual health plan from a specific insurer that still offers them.

HSAs were created in 2003 and have become the standard savings account tied to high-deductible plans. Employers offer them, insurance companies promote them, and financial institutions compete to manage them. If your employer or insurance company mentions a medical savings account, they almost certainly mean an HSA, even if they use the older term. The shift happened because HSAs are simpler, more flexible, and reach a much larger population of workers.

How to tell which account you have

Check your insurance paperwork or your employer's benefits materials. The account will be labeled as either an "HSA" or an "MSA." If it says HSA, you have an HSA. If it says MSA, you have an MSA—and you should ask your insurance company or benefits administrator about the income limits and contribution caps, because they may affect your ability to contribute or keep the account if your circumstances change.

You can also call the financial institution that holds the account. They will tell you immediately which type it is and what the rules are for your specific account. Do not assume based on the name alone, because some companies use "medical savings account" as a generic term even when they are describing an HSA. Your account statement should also clearly label which type of account it is.

Frequently Asked Questions

Can I have both an MSA and an HSA at the same time?

No. The IRS does not allow you to contribute to both in the same year. If you have an MSA and want to open an HSA, you must close the MSA or stop contributing to it. You can keep the money in the closed MSA and use it for medical expenses, but you cannot add new money to it once you open an HSA.

If I have an MSA and my income goes above the limit, what happens?

You can keep the money in the account and continue to use it for may have access to medical expenses. You just cannot make new contributions. If you want to keep saving money in a medical account, you would need to switch to an HSA, which has no income limit—but you cannot contribute to both in the same year.

Can I use HSA money for my spouse's medical expenses?

Yes. If you have family coverage on your HSA, you can use the money for may have access to medical expenses for you, your spouse, and any dependents on your plan. The money does not have to be used only for the person whose name is on the account.

What if I inherited an MSA from someone?

The rules depend on whether you inherited it from a spouse or a non-spouse. If your spouse had an MSA, you can treat it as your own and continue to use it. If a non-spouse left you an MSA, the money is taxable to you and you cannot keep it in the account. You should contact the financial institution holding the account for specific instructions on how to close it and receive the funds.

Do I need to use my HSA or MSA money by the end of the year?

No. Both accounts let money roll over indefinitely. You do not lose it if you do not spend it. However, some MSAs have restrictions if you change insurance plans—check your plan documents to see if there are any limits on how long you can keep the money after you leave the plan.
