Rolling money from a traditional IRA into an HSA turns tax-deferred dollars into tax-free withdrawals for medical bills. But you’ll maximize the tax breaks if you contribute new money to the HSA. Getty Images By Kimberly Lankford, Contributing Editor August 18, 2017 QI’m now on Medicare, but I had opened a health savings account when I was still working and was covered by a high-deductible health insurance policy. Can I transfer funds from a traditional IRA to a health savings account now? How much can be transferred?SEE ALSO: 10 Things Boomers Must Know About RMDs From IRAs AYou can only transfer money from an IRA to an HSA if you’re eligible to make new HSA contributions. Because you’ve enrolled in Medicare, you can no longer contribute to your HSA, although you can use the money in the account tax-free for eligible medical expenses. And now that you’re over 65, these expenses include Medicare parts B and D as well as Medicare Advantage premiums. People who still qualify to make HSA contributions can make a one-time rollover from an IRA to an HSA, which can be a good way to build up the account if you don’t have other cash to contribute. You must currently have an HSA-eligible health insurance policy with a deductible of at least $1,300 for single coverage or $2,600 for family coverage. The amount you can roll over is the same as your annual HSA contribution limit -- up to $3,400 in 2017 if you have single coverage or $6,750 if you have family coverage, plus an extra $1,000 if you’re 55 or older. The annual contribution limit is the same, whether the money is coming from cash or an IRA rollover or a combination of the two.

Contact your HSA administrator to find out how to do this. You can only roll money over from an IRA to an HSA once in your lifetime. Advertisement By doing a rollover, you’re converting tax-deferred dollars into tax-free money if you use the withdrawals from the HSA for medical expenses. But you’ll get an even better tax benefit if you can contribute new money to the HSA instead. That way, you can keep more money growing tax-deferred in the IRA and get a tax deduction for the new HSA contribution.
