Are HSAs Worth It in California? What High Earners Who Don’t Feel Rich Yet Should Know
If you’re a high earner in California, you’ve probably heard two things about Health Savings Accounts that seem to cancel each other out. The first is that the HSA is the most tax-advantaged account available, better than a 401(k) or a Roth IRA. The second is that California doesn’t recognize HSAs at all, so maybe the whole thing isn’t worth the trouble.
For many high-income professionals who are healthy, can comfortably cover a higher deductible, and are willing to invest the account rather than spend it, an HSA is often still worth it in California. The federal tax benefits carry most of the weight, and California’s non-conformity reduces the advantage without eliminating it. That said, it isn’t automatic. Whether it makes sense depends on how your health plan options compare, how much medical care your household actually uses, and whether your cash flow can absorb a larger deductible without strain.
This question comes up constantly with clients I’d describe as HENRYs, short for “High Earners, Not Rich Yet.” These are people earning strong incomes, often in tech, medicine, law, or finance, who still feel stretched by a Newport Beach mortgage, childcare, and the general cost of living in coastal Orange County. If that tension sounds familiar, I wrote more about it in why you can make good money and still feel behind. HENRYs are usually doing all the right things, maxing out the 401(k) and trying to save, and they want to know which account deserves the next dollar. Open enrollment is usually when the HSA question lands on my desk, and it deserves a better answer than “always” or “never.”
What Makes an HSA Different From Other Accounts?
A Health Savings Account is a personal account you can contribute to when you’re covered by a qualifying high-deductible health plan. You own it, it stays with you when you change jobs, and unlike a flexible spending account, the money doesn’t disappear at the end of the year.
At the federal level, the HSA is often described as having a “triple tax advantage.” Contributions reduce your federal taxable income, the money can grow without federal tax on interest, dividends, or gains, and withdrawals for qualified medical expenses come out federally tax-free. No other account gets all three. A traditional 401(k) gives you the deduction going in but taxes you coming out. A Roth gives you tax-free withdrawals but no deduction up front, which is part of why high earners spend so much time weighing the tradeoffs I cover in my post on when Roth conversions make sense for high-income earners in California. The HSA does both, as long as the money is used for medical costs.
There’s one more benefit that often gets overlooked. When you contribute through payroll at work, those dollars generally also avoid Social Security and Medicare payroll taxes, which is something you don’t get from contributing to an HSA on your own or even from your 401(k) deferrals.
Contribution limits are set by the IRS and adjust most years, with separate limits for individual and family coverage plus an extra catch-up amount once you reach 55. You can find the current figures in IRS Publication 969, and since these numbers shift annually, it’s worth checking the current year’s limits before setting your payroll election.
What Does California Do Differently With HSAs?
California is one of only two states with an income tax, New Jersey being the other, that doesn’t follow the federal HSA rules. The Franchise Tax Board treats an HSA much like a regular taxable investment account, which plays out in a few ways.
Your contributions aren’t deductible on your California return. If you contribute through payroll, your employer adds those dollars back into your California wages, which is why the state wage figure on your W-2 often looks higher than your federal one. If you contribute on your own, you add the deduction back when you file. Employer contributions to your HSA are treated the same way.
The growth inside the account is also taxable to California each year. Interest, dividends, and realized gains generated inside the HSA need to be reported on your state return, even though nothing is owed federally. Your HSA custodian won’t send you a neat California tax form for this, so it requires some tracking.
There is a silver lining. Because you’ve already paid California tax on your contributions and earnings along the way, those dollars build up what’s called “basis” for state purposes, meaning you generally won’t be taxed by California again when that money comes out later.
California lawmakers have introduced bills to conform to the federal HSA rules several times, including a recent proposal that would have provided state conformity for tax years 2026 through 2030. As of this writing, none have been enacted, but this is worth watching, because conformity would make the decision even easier for California residents.
So Is an HSA Still Worth It for High Earners in California?
For a lot of HENRYs, the answer leans yes, and the reason comes down to where your tax savings actually come from.
When you’re in a high federal bracket, the federal deduction alone is meaningful, and the payroll tax savings add a bit more. Losing the California deduction reduces the benefit, but most of the value was always on the federal side. The long-term growth story is even stronger. Decades of investment growth that you never pay federal tax on, as long as it’s eventually used for medical expenses, is hard to replicate anywhere else.
And you will very likely have medical expenses later in life. Healthcare costs in retirement, including Medicare premiums, many out-of-pocket costs, dental, vision, and long-term care insurance premiums within IRS limits, are often one of the larger line items in a retirement plan. An HSA built up over 20 or 30 years becomes a dedicated, tax-efficient pool earmarked for exactly that.
I worked with a couple in their late 30s, both physicians, who had been choosing the PPO every year out of habit. They were healthy, had a solid emergency fund, and had already maxed out their 401(k)s. When we sat down and compared both plan options side by side, including the premium difference and the employer’s HSA contribution, the HDHP came out ahead even before counting any tax benefit. Once we factored in the federal tax savings, the decision wasn’t close. California’s add-back didn’t change the answer, it just made their state return slightly more involved.
For many California HENRYs, the HSA is less about this year’s tax bill and more about what it can become in 25 years.
When Might an HSA Not Make Sense?
An HSA is only available if you’re on a qualifying high-deductible health plan, so the real decision usually starts with the health plan, not the account.
If someone in your household has a chronic condition, ongoing specialist care, a planned surgery, or a pregnancy on the horizon, the higher deductible could easily outweigh the tax savings. Some employers heavily subsidize their PPO, and in that case the traditional plan may simply be the better value. The network matters too, especially if a family member has established relationships with specific doctors.
Cash flow is the other factor I watch closely with HENRYs. Earning a high income doesn’t mean you have a lot of free cash each month, especially in the first years after buying a home or while paying for childcare. If a surprise deductible would put a charge on a credit card or force you to pull from investments at a bad time, the HSA’s long-term benefits may not justify the short-term stress. A healthy emergency fund comes first.
Finally, an HSA that sits in cash and gets drained each year for routine doctor visits still provides some tax savings, but it misses most of the reason the account is valuable. If you know you’ll spend it as you go, the case is weaker, though still often positive.
How Do HENRYs Get the Most Out of an HSA?
The strategy many planners talk about is treating the HSA as a long-term investment account rather than a medical checking account.
In practice, that means paying current medical bills out of pocket when your cash flow allows it, keeping digital copies of the receipts, and letting the HSA stay invested. Under current federal rules, there’s no deadline to reimburse yourself for a qualified expense as long as it was incurred after the HSA was opened. Years later, you can reimburse yourself tax-free for those saved receipts, which gives the account flexibility that looks a lot like an emergency reserve.
A software engineer I worked with had been using her HSA debit card for every prescription and copay. She had the cash flow to cover those costs herself, she just hadn’t thought about the account differently. Once she started paying out of pocket and saving receipts, her HSA balance began compounding instead of resetting each year. She now thinks of it as a long-term bucket that happens to have a medical label on it.
This is also where the HSA fits into a broader savings order. For many high earners, the priority looks something like capturing the full employer 401(k) match, building an emergency fund, then evaluating the HSA alongside maxing the rest of the 401(k) and other retirement accounts. I walk through how these pieces fit together in my post on maximizing retirement contributions to lower your taxes.
Because California taxes the HSA’s earnings each year, investment selection inside the account deserves some thought. A broad, low-turnover index fund generally creates less annual California tax than an actively managed fund that distributes gains frequently. This is one of those spots where tax planning and investment management really need to talk to each other.
What If You’re Self-Employed or Buying Your Own Insurance?
This is where recent federal changes may matter most. Beginning January 1, 2026, the One Big Beautiful Bill Act allows bronze and catastrophic plans to be treated as HSA-compatible, even if they don’t meet the traditional definition of a high-deductible plan, according to IRS guidance in Notice 2026-05. For many self-employed HENRYs buying coverage through Covered California, that opens up HSA eligibility that may not have existed before.
The same law also allows people enrolled in certain direct primary care arrangements, where you pay your doctor a flat monthly membership fee, to remain HSA-eligible and pay those fees from the HSA. It also made permanent the ability to receive telehealth services before meeting your deductible without losing HSA eligibility.
If you’ve recently left a W-2 job to start your own practice or business, health insurance is often one of the more frustrating new costs, along with the other adjustments I describe in the real financial challenges of starting a business after leaving a W-2 job. It’s worth looking at whether a qualifying plan paired with an HSA could fit into your new cash-flow picture, especially in years when your income and tax bracket are high.
Does an HSA Affect My California Tax Bill at Filing Time?
It can, and this catches people off guard. Because California taxes your HSA contributions and growth, some HENRYs are surprised to see a higher state tax bill than expected, particularly when their payroll withholding was set based on federal numbers.
It’s rarely a large difference on its own, but it stacks on top of other common gaps for high earners, like bonuses or RSU vests withheld at flat rates that don’t reflect your actual bracket. If that’s a pattern you’ve noticed, my post on why high-income earners still owe taxes even with withholding explains where those gaps usually come from.
Keeping a simple year-end record of HSA contributions, employer contributions, and any earnings inside the account makes your California return much easier to prepare correctly.
How Does an HSA Fit Into the Bigger Financial Picture?
An HSA touches more parts of your plan than most people expect.
In retirement, it can help cover healthcare costs without generating taxable income, which matters because higher taxable income can push up Medicare premiums through IRMAA, the income-based surcharge on Medicare Parts B and D. Once you’re 65, you can also withdraw HSA money for non-medical purposes without the penalty, though those withdrawals are taxed as ordinary income, similar to a traditional IRA. Before 65, non-medical withdrawals are generally subject to both income tax and an additional federal penalty, currently 20%, so confirm current rules before taking any distribution.
Where you live in retirement matters too. If you eventually move to a state that follows the federal rules or has no income tax at all, California’s drag on the account simply stops.
Estate planning is the piece people overlook. If your spouse is the beneficiary, the HSA can generally continue as their own HSA. If anyone else inherits it, such as your children, the account stops being an HSA and the full value is generally taxable to them in the year of your death. For high-income families thinking ahead, that’s a reason to coordinate beneficiary designations and consider spending HSA dollars on medical costs during your lifetime, while leaving other assets to heirs.
For tech professionals juggling equity compensation, an HSA also plays a role in managing taxable income in heavy vesting years. I cover more of that in my post on RSU and tax planning strategies for high-income professionals.
When Does It Make Sense to Work With an Advisor?
Choosing a health plan during open enrollment can feel like a benefits question, but for HENRYs it’s really a tax, cash-flow, investment, and retirement question all at once. That’s usually where things get fragmented. Your benefits portal shows premiums, your CPA sees the California add-back after the fact, and your investment advisor may not even know the HSA exists. I explain more about why that gap matters in why clients need integrated tax and financial planning.
As both a CPA and a CFP®, I find the most useful conversations happen before the enrollment deadline, when we can compare plan options using your household’s actual health usage, look at how the HSA fits alongside your 401(k), RSUs, and savings goals, and make sure the account is invested in a way that makes sense given California’s annual tax on its growth. It may be worth exploring with your advisor if you’re weighing an HDHP for the first time, recently became self-employed, or have an HSA balance sitting in cash without a clear plan.
Frequently Asked Questions
Are HSAs worth it in California?
For many healthy, high-income Californians who can comfortably cover a higher deductible, an HSA is often still worth it. The federal tax benefits and long-term tax-free growth for medical expenses usually outweigh the loss of California’s deduction. It depends on your health plan options, expected medical costs, and cash flow.
Does California tax HSA contributions?
Yes. California doesn’t follow the federal HSA rules, so contributions aren’t deductible on your California return. Payroll and employer contributions are added back into your state wages.
Do I pay California tax on HSA investment earnings?
Generally, yes. Interest, dividends, and realized gains inside your HSA are taxable to California each year, even though they’re federally tax-free. You’ll need to track these yourself because custodians don’t typically provide a California-specific form.
Are HSA withdrawals taxed in California?
Because you’ve already paid California tax on your contributions and earnings, those amounts generally form your state basis and aren’t taxed again by California when withdrawn. Federally, withdrawals for qualified medical expenses are tax-free.
Is California going to start recognizing HSAs?
Bills to conform California to the federal HSA rules have been introduced several times, including a proposal covering tax years 2026 through 2030. As of this writing, none have passed. It’s worth checking current California legislation before planning around a possible change.
Is an HSA better than a 401(k) for high earners?
They serve different roles. Many planners suggest capturing your full 401(k) employer match first, then considering the HSA because of its unique federal tax treatment for medical costs. The right order depends on your cash flow and overall plan.
Should I invest my HSA or keep it in cash?
Many people keep a portion in cash for near-term deductibles and invest the rest for long-term growth. If you can pay current medical bills out of pocket, investing the HSA allows it to compound over time. In California, low-turnover investments may reduce the annual state tax on earnings.
Can I reimburse myself from my HSA years later?
Under current federal rules, yes, as long as the expense was incurred after your HSA was opened and you keep documentation. This is why many people save receipts and reimburse themselves later. Check current IRS guidance in Publication 969 before relying on this.
Can I use an HSA with a Covered California bronze plan?
Starting in 2026, bronze and catastrophic plans are treated as HSA-compatible under federal law, which may make many Covered California enrollees newly eligible. Confirm your specific plan’s eligibility before contributing.
Can I still contribute to an HSA after age 65?
Once you enroll in any part of Medicare, you can no longer contribute to an HSA, though you can still use the existing balance. Timing around Medicare enrollment matters, especially if you’re still working past 65.
What happens to my HSA when I die?
If your spouse is your beneficiary, the account can generally continue as their HSA. If someone else inherits it, the account generally becomes fully taxable to them in the year of death, which makes beneficiary planning important.
Can I have an HSA and an FSA at the same time?
Generally, a standard health FSA (including your spouse’s) disqualifies you from contributing to an HSA. A limited-purpose FSA covering only dental and vision is usually compatible. Check your employer’s plan details before enrolling in both.
In Short
For many California HENRYs, an HSA is still often worth it because the federal tax benefits do most of the work.
California doesn’t recognize HSAs, so contributions are added back to state income and earnings are taxed by California each year.
The real decision starts with the health plan: compare premiums, employer contributions, deductibles, and your household’s actual medical usage.
The account is most valuable when you can pay medical costs out of pocket, save receipts, and keep the HSA invested.
Recent federal changes expanded HSA eligibility to bronze and catastrophic plans starting in 2026, which matters for self-employed professionals.
HSAs connect to retirement income, Medicare premiums, investments, and estate planning, so it helps to coordinate them with the rest of your plan.
Contribution limits, penalties, and California’s conformity status can change, so it’s worth confirming current numbers and rules before acting.
