Open an HSA and start receipt-stockpiling
A 12-step path to opening an HSA, moving it off the employer custodian if you have one, investing the balance, and starting the receipt-stockpile system that turns an HSA into a stealth Roth IRA. Federal mechanics. 🟢 DIY; requires HDHP enrollment.
Bridge to a licensed pro — skip this playbook if any apply
Opening and funding an HSA is DIY. The following situations warrant professional guidance:
- **HDHP + general-purpose FSA conflict.** A general-purpose healthcare Flexible Spending Account — yours or a spouse's — disqualifies you from HSA contributions for the entire plan year (26 USC § 223(c)(1)(A)(ii)). A *limited-purpose* FSA (dental/vision only) does NOT disqualify. If you or your spouse has an FSA at work, talk to HR before enrolling in the HDHP.
- **Medicare enrollment near age 65.** Once enrolled in ANY part of Medicare (including Part A, which is automatic at 65 for anyone who has taken Social Security), you are ineligible to CONTRIBUTE to an HSA. The Part-A-retroactive-6-months rule means someone who enrolls in Medicare at 65 cannot contribute for the 6 months prior. This interacts with Social Security claiming strategy. Consult a fee-only advisor or CPA if planning to delay Medicare or continue working past 65.
- **Over-contribution correction.** If you over-contributed in a year (common when HDHP coverage changes mid-year, or when both spouses have HSAs), you must withdraw the excess + earnings before your tax-filing deadline (including extensions) or pay a 6% excise tax per year until corrected (IRC § 4973). A CPA can handle the corrective distribution form.
- **Inheriting an HSA as a non-spouse.** Only a spouse can inherit an HSA as-an-HSA. A non-spouse beneficiary must liquidate and pay income tax on the full balance (no stretch available). If planning to leave an HSA to a non-spouse, consider spending it down for qualified medical expenses first — attorney / CPA conversation about inheritance sequencing.
- **HSA with employer contribution + plan restrictions.** Some employer HSAs require contributions stay with the employer's custodian for a holding period (e.g., 30 days) before transfer. Read the plan document or confirm with HR.
When none of these apply, the 12-step checklist below takes most families from no-HSA to fully-automated-and-invested in a single afternoon.
State-specific flags
2025/2026 HSA contribution limits — IRS Rev. Proc. 2024-25 + IR-2025-94
2025: $4,300 self-only / $8,550 family. 2026: $4,400 self-only / $8,750 family. Catch-up (age 55+): $1,000 (not indexed for inflation). Limits are PRO-RATED if you had HDHP coverage for only part of the year — except if you're HDHP-covered on December 1 + stay covered through the following December 1 (the last-month rule), in which case you can contribute the full year's limit.
Spousal HSA — separate accounts, shared family limit
If both spouses have HDHP coverage, each spouse can have their own HSA and take their own $1,000 catch-up at 55+. The $8,550/$8,750 FAMILY limit is shared — allocate however you choose. A common strategy: fund the younger spouse's HSA (longer compounding runway), then once both hit 55, split contributions to claim both catch-ups.
Qualified medical expenses — IRS Publication 502
Definitive list at IRS Pub 502. Notable expansions: OTC medications (CARES Act 2020, permanent), menstrual products (CARES Act 2020, permanent). Notable exclusions: cosmetic procedures, health-club dues, general vitamins. Medicare Part B + Part D + Medicare Advantage premiums qualify after 65; Medigap does not. Long-term care insurance premiums qualify up to IRC § 213(d)(10) age-based caps (adjusted annually).
Virginia HSA — full conformity with federal rules
Virginia conforms to federal HSA treatment — contributions reduce Virginia AGI; growth is state-tax-free; qualified withdrawals are state-tax-free. Payroll contributions additionally avoid Virginia income-tax withholding. No Virginia-specific form beyond Form 760 itself.
West Virginia HSA — full conformity with federal rules
West Virginia conforms to federal HSA treatment — contributions reduce WV AGI, growth is state-tax-free, qualified withdrawals are state-tax-free. As WV's income-tax transition completes (flatter structure by 2026), HSA treatment is unchanged; it's AGI-reducing at the contribution step.
Alabama HSA add-back — contributions NOT state-deductible
Alabama decoupled from the federal HSA deduction in 2017 and has not reconformed. Contributions ARE federally deductible (and avoid federal FICA if via payroll), but Alabama requires an add-back at the state level — HSA contributions do not reduce Alabama AGI. Roughly 5% of the contribution is lost to Alabama income tax. Alabama residents should still max the HSA despite this — the federal triple-tax advantage + FICA savings far outweigh the 5% state-level gap. Track the add-back on Alabama Form 40 Schedule W, line 5.

1.Confirm HDHP eligibility
You must be enrolled in a High-Deductible Health Plan (HDHP) to contribute to an HSA. **2025 HDHP minimums (IRS Rev. Proc. 2024-25):** deductible ≥ $1,650 self / $3,300 family; out-of-pocket max ≤ $8,300 self / $16,600 family. Check your health plan's Summary of Benefits and Coverage — it should say "HSA-eligible" or "qualified HDHP." Also confirm NO disqualifying coverage: general-purpose FSA (yours or spouse's), TRICARE, Medicare, VA medical benefits in the last 3 months, or being claimed as a dependent on someone else's return. A limited-purpose FSA (dental/vision only) is OK. An HRA can be OK depending on design.
2.Pick a custodian — Fidelity is usually the right default
The HSA market has four tiers: (1) **Fidelity HSA** — zero maintenance fee, $0 investment minimum, full Fidelity fund lineup including zero-ER index funds (FZROX/FZILX), no cash-sweep-minimum. Almost always the right answer for a DIY HSA. (2) **Lively + Schwab** — zero fee, integrates with Schwab brokerage. Comparable. (3) **HSA Bank / Bank of America / Optum / HealthEquity** — common employer-default custodians; typically $3-5/month fee + $1k-2k minimum cash sweep before investing is allowed. Move money out. (4) **Local credit union / community bank HSA** — usually no investment option, interest-bearing only. Avoid. Your employer's HSA (if any) must accept contributions through their custodian; you can still transfer OUT regularly.
3.Open the HSA
At Fidelity: fidelity.com → Open an Account → Health Savings Account. 10-minute form — Social Security number, beneficiary, HDHP confirmation. No credit check. Funding not required at opening. Name a **primary beneficiary** (usually spouse for the spousal-HSA-treatment rule) and **contingent beneficiary**. Review the account agreement for the custodian's position on closing / transferring.
4.Connect to payroll if possible (FICA savings)
Employer payroll contributions to an HSA (via a § 125 cafeteria plan) are exempt from federal + state income tax AND from FICA (7.65%) — this is the only retirement vehicle that avoids FICA. If your employer offers payroll HSA contributions, turn them on even if the destination custodian is not your preferred one. You can transfer OUT periodically (see step 5). Target the full IRS annual limit: **2025** $4,300 self / $8,550 family; **2026** $4,400 self / $8,750 family; add $1,000 catch-up at 55+. If payroll deduction isn't available (self-employed, gig worker), contribute directly to Fidelity via ACH — same tax deduction on Form 8889, but you miss the 7.65% FICA savings (~$500/yr for a family hitting the limit).
5.Consolidate from employer HealthEquity / Optum via custodian-to-custodian transfer
If your employer's HSA is at a fee-charging custodian (HealthEquity, Optum, BofA, etc.), do a **custodian-to-custodian transfer** from employer-HSA → Fidelity HSA. This is NOT a distribution — no tax, no 1099-SA. Fidelity's HSA Transfer Form (downloadable from fidelity.com) authorizes Fidelity to pull funds directly. Takes 3-6 weeks. IRS allows UNLIMITED custodian-to-custodian transfers per year (unlike the 1-per-12-months rollover rule). A good cadence: transfer quarterly once the employer HSA balance hits ~$1,000. Keep the employer HSA OPEN so payroll contributions keep flowing in + keep avoiding FICA.
6.Invest the HSA balance — do not leave it in cash
Inside Fidelity HSA, click Transfer Money → buy a diversified fund allocation. For a long-horizon (20+ year) HSA, a simple three-fund portfolio works: 60-80% **FZROX** (Fidelity ZERO Total Market), 15-30% **FZILX** (Fidelity ZERO International Index), 10-20% **FXNAX** or **BND** (bonds, if desired). Or a single target-date index fund matching your expected "spend the HSA on medical" decade (ideally age-65+ for receipt-stockpilers). Leaving the HSA in cash-sweep at ~4% APY is a WASTE of the tax-free-growth wrapper; over 30 years the difference between cash and equities is the difference between an HSA worth $200k vs $1M on the same contributions.
7.Set up the receipt-stockpile system
The KEY INSIGHT. IRS has no time limit on reimbursing qualified medical expenses from an HSA. Pay 2026 medical bills with after-tax cash, SAVE EVERY RECEIPT, let the HSA grow invested for 20-30 years, then reimburse yourself tax-free decades later for those 2026 expenses. Setup: (a) a mobile scanner app (Adobe Scan, Genius Scan, CamScanner — any of these) for quick phone capture. (b) A cloud folder (Google Drive / Dropbox / iCloud) named "HSA receipts YYYY" with subfolders per year. (c) A running spreadsheet — Date | Provider | Amount | Category | Receipt-file path. Scan every medical receipt same-day (easier to stay on top of 1 receipt than 50 at year-end). Include: co-pays, prescriptions, dental, vision, LASIK, mental-health, fertility treatment, OTC medications (expanded permanently in 2020 under CARES), menstrual products (also 2020), and Medicare premiums (after 65).
8.File the year's Form 8889 with your tax return
Every year you contributed to, or distributed from, an HSA, you file IRS Form 8889 with your 1040. Line 2 = your direct (non-payroll) contributions. Line 9 = employer + payroll contributions. Line 14a = total distributions taken this year (reimbursements + direct payments from HSA debit card). Line 15 = the portion that was for qualified medical expenses. Keep the Form 8889 with your tax records — audit retention target is 7 years. Most tax software (TurboTax, FreeTaxUSA, H&R Block) handles Form 8889 automatically; you enter HSA contributions + distributions and it generates the form.
9.Track qualified medical expenses for future reimbursement
List every qualifying medical expense paid with after-tax cash (outside the HSA) in a master "unreimbursed" spreadsheet — Date | Provider | Amount | Receipt-file path | Reimbursed? (Y/N). This is your future tax-free-withdrawal credit. At any point in the future, you can withdraw that amount from the HSA tax-free and cite the old receipts as justification. Keep this list forever. Qualifying expenses defined in **IRS Publication 502**: deductibles, copays, prescriptions, dental, vision, OTC medications (post-2020), menstrual products (post-2020), LASIK, mental-health, fertility treatment, long-term care insurance premiums (up to age-based caps), Medicare Part B + D + Medicare Advantage premiums (after 65 only — Medigap doesn't qualify).
10.Update the review cadence to match life stages
At 55: contribution limit rises by $1,000/yr (catch-up — paid from your own HSA; a spouse with a separate HSA gets their own catch-up). At 65: HSA contributions STOP (Medicare enrollment disqualifies you). HSA withdrawals continue tax-free for qualified medical forever; non-medical withdrawals are penalty-free (20% penalty waived) but taxed as ordinary income — treatment identical to a traditional IRA. The practical plan: contribute max every year until 65, stockpile receipts, draw on the HSA only for Medicare premiums + ongoing medical in retirement, never deplete the growth wrapper until late in retirement if possible.
11.Name / update beneficiaries — spouse vs non-spouse rules differ dramatically
Spouse as beneficiary: the HSA transfers to the spouse AS an HSA, continues tax-free-growth treatment, retains all benefits. Non-spouse as beneficiary (children, other family, a trust): the HSA is LIQUIDATED on date of death — full balance becomes taxable income to the beneficiary in that year. No stretch, no Roth-style rollover. For a $500k HSA in a 32% bracket, that's $160k of tax. If you have a large HSA and a non-spouse beneficiary is likely (single, widowed, kids as beneficiaries), plan to draw it down for medical expenses before death OR name a spouse/charity primary and non-spouse only as contingent. Update beneficiary at Fidelity portal anytime — it takes 2 minutes; do it after any major life event (marriage, divorce, spouse's death, child's birth).
12.Year-over-year receipt-stockpile review
Once a year (tax-filing season is a natural trigger): confirm the year's receipts are all scanned + in the cloud folder + tallied in the spreadsheet. Sum the year's unreimbursed medical. Add it to the cumulative unreimbursed total. Compute what percent of the HSA balance the cumulative unreimbursed represents — your "tax-free withdrawal buffer." Back-test: ask "if I needed to withdraw $X tax-free today, could I justify it with receipts?" If yes, you have optionality. If the HSA balance has grown faster than the stockpile of unreimbursed, you're building long-horizon tax-free growth even more effectively.
