HSA vs FSA Checklist (2026) | HSA Tracker

Confirm you are enrolled in a qualifying High-Deductible Health Plan (HDHP).

This is the absolute requirement for HSA eligibility. For 2026, the HDHP must have a minimum deductible of $1,700 for self-only coverage or $3,400 for family coverage. Without this plan, an HSA is off the table.

Verify your HDHP's out-of-pocket maximum does not exceed IRS limits.

Even with a high deductible, your plan must cap total patient costs. For 2026, the maximum out-of-pocket for an HSA-qualified HDHP is $8,500 (self) or $17,000 (family). Plans with higher maximums disqualify you.

Check that you have no other disqualifying health coverage.

You cannot be covered by a spouse's non-HDHP plan, a general-purpose Health FSA, or Medicare and still contribute to an HSA. Other specific coverages like TRICARE may also affect eligibility.

Determine if your employer offers a health FSA.

If your employer offers a general-purpose health FSA, you likely cannot open an HSA unless you waive the FSA or it's a limited-purpose type. This is a common trap for W2 employees.

Review your plan's HSA eligibility determination with HR or the provider.

Don't assume your HDHP is HSA-eligible. Some HDHPs have embedded features (like low deductibles for specific services) that break the rules. Get official confirmation from your plan administrator.

Understand the 'first-month' rule for partial-year HSA eligibility.

If you become eligible for an HSA (e.g., switch to an HDHP) on the first day of any month, you can contribute the full annual amount for that year, even if eligible for only one month.

Check FSA enrollment deadlines and any required election amounts.

FSAs require a pre-tax election during open enrollment or upon a qualifying life event. You generally cannot change this amount mid-year unless your situation changes. Plan your expected expenses carefully.

Apply the correct 2026 HSA contribution limit based on your coverage.

For self-only HDHP coverage, you can contribute up to $4,400. For family coverage, the limit is $8,750. Contributing over these limits results in a 6% excise tax each year until corrected.

Apply the 2026 health FSA contribution limit of $3,400.

This is the maximum you can elect to put into a health FSA for the plan year. Unlike an HSA, this is a use-it-or-lose-it election, so accuracy is key to avoid forfeiting money.

Add the $1,000 HSA catch-up contribution if you are 55 or older.

This is an extra amount you can contribute to your HSA, but only if you are not enrolled in Medicare. This boosts your retirement healthcare savings significantly over time.

Note that FSAs have no catch-up contribution provision.

Regardless of age, the FSA limit is fixed. This is a structural difference that makes HSAs more powerful for older workers planning for retirement healthcare costs.

Coordinate HSA contributions if both spouses have separate HSAs.

The $8,750 family limit is a household limit, not per-person. If both spouses have HSAs, their combined contributions cannot exceed the family limit, plus any individual catch-up contributions.

Plan FSA contributions based on predictable, known expenses.

Since FSA funds may be forfeited, base your election on solid estimates for items like copays, prescriptions, glasses, or dental work. Avoid guessing high on 'maybe' expenses.

Consider front-loading HSA contributions early in the year.

Funding your HSA early gives the money more time to grow tax-free if invested. It also ensures funds are available if a major medical expense occurs early in the plan year.

Understand the separate $7,500 limit for a Dependent Care FSA.

This is a completely separate account for childcare or adult dependent care expenses. You can have both a health FSA and a Dependent Care FSA, but their limits are independent.

Confirm that your HSA is held in your name at a provider you choose.

HSAs are individual accounts. Even if offered through work, you own it. You can often move it to a provider like Fidelity or Lively for better investment options and lower fees.

Verify your HSA funds roll over 100% year to year, indefinitely.

There is no deadline to spend HSA money. Unused funds remain yours forever, allowing you to save for future major expenses or retirement. This is a core advantage over FSAs.

Check your employer's specific FSA rollover or grace period policy.

The default is 'use-it-or-lose-it.' Your employer may offer the $680 carryover option or a 2.5-month grace period. You must know which applies to avoid surprise forfeitures.

Plan for HSA portability if you anticipate changing jobs.

Your HSA balance is not tied to your employer. You keep it when you leave. Factor this into career decisions, as it provides continuity in your healthcare savings strategy.

Understand that FSA access typically ends when employment ends.

If you leave your job, you usually lose access to your FSA funds immediately, unless you elect COBRA for the FSA (which can be expensive). This adds risk for job-changers.

Evaluate HSA investment options for long-term growth.

Once your HSA balance reaches a certain threshold (often $1,000), you can invest in mutual funds or ETFs. This turns it into a powerful retirement savings tool with triple tax advantages.

Note that FSAs have no investment component.

FSA funds are purely a pre-tax spending account. They do not earn interest or investment returns. This makes them a short-term savings tool, not a long-term wealth builder.

Use the IRS Publication 502 list as the guide for qualified medical expenses.

Both accounts follow the same basic list for eligible expenses, including doctors, dentists, prescriptions, and many over-the-counter items. This is your primary reference to avoid non-qualified purchases.

Save receipts and documentation for all HSA and FSA purchases.

The IRS can audit these accounts. You must be able to prove that withdrawals paid for qualified medical expenses. Keep records for as long as you have the account, plus several tax years.

Remember the 20% penalty for non-qualified withdrawals applies to both.

If you use HSA or FSA funds for a non-eligible expense, you'll owe income tax plus a 20% penalty on the amount. This is a significant deterrent against misuse.

Note the HSA penalty waiver for non-medical withdrawals after age 65.

This transforms the HSA. After 65, you can withdraw for any reason penalty-free (you still pay income tax), making it function like a traditional IRA for retirement income.

Confirm if your FSA requires submission of receipts for reimbursement.

Many FSAs work with a debit card, but you may still need to submit receipts to justify the expense to your plan administrator. Failure to do so could lead to having to repay the funds.

Understand that HSA funds can be used for qualified expenses from any prior year.

You can reimburse yourself from your HSA for a qualified expense you paid out-of-pocket years ago, as long as the expense occurred after the HSA was opened. This allows for strategic tax-free growth.

Know that FSA funds are only for expenses incurred during the plan year.

You cannot use current FSA funds to pay for last year's bills or save them for future years (beyond any carryover/grace period). Timing of the expense is strict.
