Health Savings Accounts for Tech Workers

A Health Savings Account (HSA) is a tax-advantaged account available to people enrolled in a High Deductible Health Plan (HDHP). You contribute pre-tax dollars, the money grows tax-free, and withdrawals for qualified medical expenses are tax-free. No other account in the U.S. tax code offers this triple tax advantage — not a 401(k), not a Roth IRA, not a 529.

For tech workers at well-compensated companies, the HSA is often the most underutilized account available. Most FAANG-adjacent employers offer HDHPs alongside traditional PPO plans, frequently with an employer HSA contribution on top. Yet the majority of employees either skip the HDHP in favor of a lower-deductible plan or, if they do enroll, treat the HSA as a healthcare checking account rather than a long-term investment vehicle.

How an HSA Works

To open and contribute to an HSA, you must be enrolled in an HSA-eligible HDHP — a health plan with a minimum deductible of $1,700 for self-only coverage or $3,400 for family coverage in 2026, and maximum out-of-pocket limits of $8,500 (self-only) or $17,000 (family). You cannot be enrolled in Medicare, be claimed as a dependent on someone else's return, or have a spouse with a non-HDHP FSA that covers you.

Once enrolled, you contribute to the HSA — either directly or through payroll deduction — up to the annual IRS limit. The 2026 contribution limits are $4,400 for self-only coverage and $8,750 for family coverage. If you are 55 or older, you can contribute an additional $1,000 per year as a catch-up contribution. Unused balances roll over indefinitely — there is no "use it or lose it" rule, unlike a Flexible Spending Account (FSA).

The Triple Tax Advantage

The HSA's defining feature is that it is the only account in the tax code that avoids taxation at every stage:

• Contributions are pre-tax. Money contributed through payroll deduction avoids federal income tax and FICA payroll taxes (Social Security and Medicare — a 7.65% saving on top of income tax). Contributions made directly and deducted on your return save income tax but not FICA. For a tech worker in the 32% or 37% federal bracket, every dollar contributed through payroll saves $0.40–$0.45 in combined federal income and payroll tax.
• Growth is tax-free. HSA balances can be invested in mutual funds, ETFs, or index funds — just like a brokerage account — and dividends, interest, and capital gains accumulate without any annual tax drag.
• Withdrawals for qualified medical expenses are tax-free. Qualified expenses include deductibles, copays, prescriptions, dental, vision, and a broad range of medical costs. There is no time limit on reimbursement — you can pay a medical expense out of pocket today, save the receipt, and reimburse yourself from the HSA years or decades later.

After age 65, the HSA converts to a de facto traditional IRA: you can withdraw for any purpose and pay ordinary income tax on non-medical withdrawals, with no penalty. For medical expenses it remains tax-free at any age. This makes the HSA strictly better than a traditional IRA — same tax treatment after 65, plus tax-free withdrawals for medical at any age.

HSAs at FAANG Companies: What Employers Contribute

Most large tech companies offer at least one HDHP option alongside traditional PPO plans, and many seed the HSA with an employer contribution to offset the higher deductible. Specific employer contributions vary by year and plan election, but documented examples from recent years give a sense of scale:

• Google (Alphabet): Has offered HSA contributions of approximately $1,350–$1,600 for self-only and $2,700–$3,200 for family coverage depending on the plan year, deposited at the start of the year. Combined with the employee contribution limit, a Google employee on a family plan can enter the year with over $11,000 already allocated to the HSA.
• Amazon: Offers HDHPs through its medical plan options and contributes to employee HSAs — reported amounts have been in the range of $500–$1,500 for self-only coverage. Amazon's specific contribution varies by plan tier and changes annually.
• Meta: Has offered employer HSA contributions and covers a significant portion of premiums on its HDHP options. Meta's total compensation philosophy extends to benefits, with the HDHP often carrying lower premiums than the PPO at the expense of a higher deductible.
• Microsoft: Contributes to employee HSAs — reported contributions have been around $1,000 for self-only and $2,000 for family coverage. Microsoft also offers HSA investment options with no minimum balance required before investing.
• Apple: Offers HSA-eligible plans with employer contributions. Apple employees have reported employer seeding in the $500–$1,000 range for self-only plans.

These figures change annually and vary by the specific plan elected. The key point: at most large tech companies, the employer HSA contribution partially or fully offsets the higher deductible of the HDHP relative to a PPO — which means the HDHP is often the financially superior choice even before accounting for the tax savings on contributions.

HDHP vs. PPO: The Math for Tech Workers

The common objection to HDHPs is the higher deductible — the amount you pay out of pocket before insurance kicks in. For a healthy tech worker in their 30s who rarely uses medical care, this concern is usually unfounded on the numbers.

Consider a simplified comparison for a single employee at a Bay Area tech company:

• PPO: $200/month premium ($2,400/year), $500 deductible, $30 copays
• HDHP: $50/month premium ($600/year), $1,650 deductible, employer contributes $1,350 to HSA

The premium difference alone saves $1,800/year on the HDHP. Add the $1,350 employer HSA contribution and you are ahead by $3,150 before using a single dollar of medical care. The HDHP only becomes more expensive if you hit the full deductible every year and use no PPO benefits — an unlikely scenario for a healthy individual. For families with predictable, high medical usage, the comparison is closer and requires case-by-case analysis.

The HSA as a Retirement Account: The Investor's Approach

Most people use their HSA as a healthcare checking account — money goes in, medical bills come out. This is leaving significant value on the table. The more powerful approach for high earners with sufficient cash flow is to treat the HSA as an additional retirement account:

1. Pay all medical expenses out of pocket. Use your regular income or savings for current medical costs instead of drawing from the HSA.
2. Invest the full HSA balance. Most HSA providers allow you to invest in index funds once the balance exceeds a threshold (often $1,000–$2,000). Move the balance above the threshold into low-cost equity funds.
3. Save every medical receipt. The IRS imposes no time limit on HSA reimbursements. A medical expense paid in 2026 can be reimbursed from the HSA in 2036 — tax-free, with no documentation deadline. Saving receipts creates a growing pool of future tax-free withdrawal capacity.
4. Withdraw years later. In retirement, use accumulated receipts to make large tax-free withdrawals from the HSA — effectively unlocking years of tax-free investment growth on medical expenses you already paid out of pocket.

A tech worker who contributes $4,400/year to an HSA for 20 years and invests the full balance at a 7% real return accumulates approximately $180,000. If they saved $4,000/year in out-of-pocket medical receipts over the same period, they can withdraw $80,000 of that balance completely tax-free (reimbursing old expenses), and the remaining $100,000 converts to penalty-free retirement income after 65 — taxed like a traditional IRA withdrawal. On a family plan at $8,750/year, the 20-year balance approaches $360,000.

California: The HSA Exception That Costs Real Money

California is the only remaining state that does not recognize the federal HSA tax exemption. The consequences are specific and significant:

• Contributions are not deductible from California state income tax. Whether you contribute through payroll deduction or directly, the HSA contribution does not reduce your California taxable income. At California's top marginal rate of 13.3%, a $4,400 self-only contribution costs $585 more in state tax than it would if California recognized the deduction.
• Investment earnings inside the HSA are taxable in California. Dividends, interest, and capital gains generated within the HSA must be reported on your California return each year — exactly as if the account were a standard taxable brokerage account. This creates a compliance burden: you need to track the HSA's investment activity and report it annually to the California Franchise Tax Board.
• Withdrawals for medical expenses are still California tax-free. California does not tax qualified HSA withdrawals — only the accumulation phase is affected. This partially preserves the value of the account for California residents, but the federal triple tax advantage is reduced to a double tax advantage at the state level.

For a senior software engineer in California earning $350,000 and maxing an HSA at $8,750/year on a family plan, the California non-conformity costs roughly $1,160 in additional state income tax on contributions annually, plus annual state tax on investment earnings within the account. Over 20 years, this adds up to real money — but the federal tax savings still dwarf the California cost, and the HSA remains worth maximizing for California residents despite the state-level friction.

Washington State: Full Federal Benefit, No State Tax

Washington has no state income tax, which means Washington-based tech workers — including the large population employed at Amazon, Microsoft, and their suppliers in the Seattle area — capture the full federal HSA tax advantage with no state-level offset. Every dollar contributed through payroll avoids federal income tax and FICA payroll taxes. Investment growth is completely untaxed at both federal and state levels. Qualified withdrawals are tax-free federally and there is no state income tax to owe.

For a Seattle-area software engineer in the 32% federal bracket contributing $8,750/year on a family plan through payroll deduction, the combined federal income tax and FICA savings are approximately $3,500 per year — pure value that requires no additional action beyond enrolling in the HDHP and electing payroll deduction. Washington's lack of state income tax makes the HSA one of the cleanest tax arbitrages available to tech workers in the region.

Common HSA Mistakes

Mistake 1: Choosing the PPO Without Running the Numbers

Many employees default to the PPO because it feels safer — lower deductible, familiar copay structure. But for healthy employees with low medical utilization, the HDHP plus HSA contribution frequently produces a lower total cost (premiums plus out-of-pocket plus tax savings) than the PPO. Before open enrollment, model both options with your actual expected medical usage. Most HR portals include a comparison tool; use it with realistic numbers, not worst-case assumptions.

Mistake 2: Leaving the HSA in Cash

The default investment option in most HSA accounts is a cash or money market fund. Many employees never change this, leaving a growing balance earning near-zero returns when it could be invested in index funds. Check your HSA provider's investment options, set up automatic investment above the required cash threshold, and treat the HSA like any other investment account.

Mistake 3: Using HSA Funds for Small Current Expenses

Paying a $25 copay from the HSA today forfeits decades of tax-free compounding on that $25. For tech workers with sufficient cash flow to cover day-to-day medical costs from their paycheck, paying out of pocket and letting the HSA compound is almost always the better long-term choice. The exception: if you are carrying high-interest debt, the math may favor using HSA funds for medical costs and directing cash toward debt payoff.

Mistake 4: Not Tracking Receipts

The ability to reimburse past medical expenses from the HSA years later is one of the most valuable HSA features — and one of the most commonly overlooked. It requires keeping records of qualified medical expenses paid out of pocket. A simple system: photograph or scan every EOB (Explanation of Benefits), medical invoice, pharmacy receipt, and dental bill, and store them in a dedicated folder. This growing stack of receipts represents future tax-free withdrawal capacity that compounds alongside the HSA balance.

Mistake 5: California Residents Skipping Annual State Tax Reporting

California requires HSA account holders to report investment income generated within the account on their state return each year. Many residents are unaware of this requirement and omit it. HSA providers are required to report distributions on Form 1099-SA but may not provide a California-specific earnings statement. You may need to request the annual account activity from your HSA custodian and report dividends and capital gains on Schedule CA. Failure to report can result in underpayment penalties from the FTB.
