HSAs and 401ks—Better Together (Part One)

HSA and 401ks

A supermajority of employers has denied their workers access to America’s most valuable benefits tax preference—the Health Savings Account (HSA). Only 17% of surveyed employers who offer health coverage offer an HSA-capable option.[i] Few use automatic features.[ii] Even fewer structure their employer HSA contributions as a match to encourage worker contributions.[iii]  

For plan sponsors pursuing a “health and wealth” strategy, failure to offer a 401k and an HSA is a mistake. These two, better together, create a unique engagement lever. 

Over-insurance impedes retirement savings 

Consistent with Liberty Mutual’s tagline, workers should select health coverage so they “only pay for what you need.” [iv] Average spend on medical services for more than 50% of Americans is less than $400 a year.[v] Excluding Medicare-eligible Americans (age 65+ and disabled), health expenditure data suggest that four out of five Americans spend less than $1,000 a year on medical services. 

“Plan sponsors can remove any barriers that would impede workers from maximizing the value from both the HSA and 401k.”

Unfortunately, many let biases control benefits decision-making. Many Americans are risk averse. Many are financially fragile. Biased decision-making leads many to purchase more medical coverage than needed. 

Generally, HSA-capable coverage comes as a choice, often with a lower employee contribution coupled with higher point-of-purchase cost-sharing (deductibles, etc.) What biases prompt individuals to over-insure and reject HSA-capable coverage? 

Further, many employers “nudge” workers to over-insure by limiting the coverage choices: 

Researchers found that workers who over-insure are more likely to forego employer-matching contributions for retirement saving. In one study, one-third of employees overpaid $1,700/year for health coverage and simultaneously made no voluntary retirement contributions. The losses were highest for employees with lower salaries, lower educational attainment and for women. Simply, consumers could redirect money away from health coverage to retirement savings without sacrificing consumption.[vi] However, a more accurate description is that by redirecting the savings from lower employee contributions, workers could invest those monies in their Health Savings Account—offering maximum utility along the way to and throughout retirement:[vii] 

The most tax-efficient way to reallocate funds currently spent as employee contributions for medical coverage would be to enroll in HSA-capable coverage and use cafeteria plan automatic enrollment defaults to redirect monies to the HSA. Other studies show consumers who are enrolled in HSA-capable coverage options are the most engaged of all health plan consumer categories.[viii]

Prioritizing savings—Which comes first, the “HSA chicken” or the “401k nest egg”?

Long ago, W. Scott Simon, then at Morningstar, argued in favor of prioritizing saving in the HSA before the 401k, asserting that: “… employees should first max out contributions to their HSAs no matter their tax bracket, and once that’s done, contribute to their 401(k) plans. HSA tax savings even beat the employer’s match.” [ix]

While I have been a champion of HSAs since 2004, I respectfully disagree with his prioritization. My decades of practical experience suggests a more nuanced approach based on each worker’s financial situation. 

Best: For those who can afford it, max out both HSA and 401k contributions and do so as early in the year as possible. For an age 55+ single worker, that is almost $35,000 pre-tax in 2023.[x] Those who can afford such funding levels might also consider Roth. Why max out, and max out early? The future is guaranteed to no one.  

Next best:  Most workers can’t afford to save the max. Most retirement experts suggest savings of at least 15% of pay per year. So, workers should prioritize contributions so that:

Note that many structure employer contributions to Health Savings Accounts so that they comply with the comparability requirements—allowing for considerable discretion on the timing of employer contributions. For example, some “front load” a portion or all of the employer contribution. For comparison, only 1 in 20 HSAs use a match similar to that used by many, perhaps most 401k plans.       

For the rest—including the financially fragile: Many workers are financially unable or unwilling to contribute to both the HSA and the 401k at the same time. To ensure workers receive the full employer financial support, a plan sponsor will want to: 

Much depends on your specific plan provisions, employer contributions, etc. Remember that HSA employee contributions, similar to 401k contributions in most plans, can be prospectively changed during the year—increased, reduced, stopped and (re)started. And, like 401k plans, plan sponsors can (re) enroll, or auto-escalate HSA contributions. Importantly, financially fragile workers may need to leverage the 401k’s tax-preferred liquidity to fund the HSA. 

Plan sponsors can remove any barriers that would impede workers from maximizing the value from both the HSA and 401k by:

Kaiser Family Foundation, 11/12/21. “… the 50% of the population with total health spending below or equal to the 50th percentile accounted for only 3% of all health spending; the average spending for this group was $374 in 2019. Roughly 14% of the population had $0 in health expenditures in 2019. Health spending is concentrated even within populations with relatively high average health costs. Among people reporting fair or poor health, the top 10% of people with the highest health spending accounted for 50% of total health spending. Considerable spending variation exists between those who are 65 and over and those under the age of 65, with younger persons experiencing more concentrated health spending. In 2019, just over half of all health expenditures among adults ages 18 through 64 was concentrated in people in the top 5% of total health spending while almost half of all health expenditures among adults 65 or older was concentrated in people in the top 10% of total health spending.

That is, regardless of when the contributions arrive in the Health Savings Account, all eligible expenses incurred on or after the date the HSA account was opened will qualify for tax favored reimbursement.
