Open Enrollment Money Checklist 2026: How to Compare Health Plans, HSAs, FSAs, and Employer Benefits
The lowest-premium health plan is not always the least expensive plan. A better open enrollment decision starts with your expected healthcare use, then compares premiums, cost sharing, tax-advantaged accounts, employer contributions, and the financial risk of an unexpectedly expensive year.
Use this 2026 open enrollment money checklist to evaluate the complete benefits package—not just the number deducted from each paycheck. The federal limits below apply to 2026, but your employer may offer lower contribution limits or different plan features. Confirm every election in the official plan documents before enrolling.
1. Start With Your 2026 Healthcare Forecast
Begin by listing the healthcare services your household is reasonably likely to use. You cannot predict every diagnosis, but you can identify recurring expenses and known events.
- Primary care, pediatric, specialist, and urgent care visits
- Maintenance and specialty prescriptions
- Physical therapy, counseling, or other recurring treatment
- Pregnancy, delivery, fertility treatment, or family planning
- Planned procedures, imaging, laboratory work, or surgery
- Dental treatment, glasses, contact lenses, or hearing care
- Medical equipment and ongoing treatment for chronic conditions
Review the previous year’s explanation-of-benefits statements, pharmacy history, and account transactions. Separate spending into predictable costs and possible high-cost events. For example, six therapy appointments are relatively predictable; an emergency room visit is not, but it belongs in a high-use scenario.
Verify providers and prescriptions
Do not assume that a doctor who accepts your current plan will remain in-network in 2026. Search each plan’s current provider directory and confirm participation directly with the provider when continued access is important. Check physicians, hospitals, laboratories, imaging centers, therapists, and pharmacies.
Also review the plan’s drug formulary. Confirm each medication’s coverage tier, copay or coinsurance, quantity limits, prior-authorization requirements, and rules for generic or mail-order alternatives. A plan with lower premiums can become expensive if it excludes a recurring prescription or places it on a high-cost tier.
Account for household changes
Consider whether 2026 may bring marriage, divorce, a new child, a dependent aging out of coverage, Medicare enrollment, or a job change. These events can affect eligibility, tax-account contributions, and whether employer or Marketplace coverage is more practical.
Finally, estimate the largest medical bill your household could reasonably face. That does not mean assuming the worst possible catastrophe. It means asking whether you could manage a deductible, hospital admission, expensive medication, or several months of specialist care without taking on high-interest debt.
2. Compare the Total Cost of Each Health Plan
Calculate annual premiums before comparing deductibles. Multiply the employee deduction by the number of pay periods:
- Weekly payroll: deduction × 52
- Biweekly payroll: deduction × 26
- Semimonthly payroll: deduction × 24
- Monthly payroll: deduction × 12
For example, a plan costing $220 per biweekly paycheck has an annual employee premium of $5,720. A competing plan costing $140 per paycheck has an annual premium of $3,640. The second plan saves $2,080 in premiums, but that does not automatically make it the better choice.
Model three usage scenarios
Compare each plan under low-, medium-, and high-use assumptions:
| Scenario | Possible assumptions | Costs to compare |
|---|---|---|
| Low use | Preventive care, one sick visit, and inexpensive prescriptions | Premiums plus expected copays and prescription costs |
| Medium use | Several office visits, therapy, testing, and recurring prescriptions | Premiums plus deductible, copays, and coinsurance |
| High use | Hospital care, surgery, pregnancy, or extensive specialist treatment | Annual premiums plus the applicable out-of-pocket maximum |
Subtract employer HSA or reimbursement contributions when comparing the employer-funded value of the plans. Keep your own HSA or FSA deposits separate: they are still your money, even when contributed before tax.
For a simplified worst-case comparison, use:
Annual employee premiums + in-network out-of-pocket maximum − employer-funded account contributions
This calculation does not capture uncovered services, out-of-network balance bills, or nonmedical costs, but it provides a useful risk benchmark.
Read the Summary of Benefits and Coverage
Compare deductibles, office-visit copays, prescription costs, coinsurance, and out-of-pocket maximums. Then review the Summary of Benefits and Coverage and plan certificate for details that comparison charts may omit:
- Services excluded from coverage
- Referral and prior-authorization requirements
- Separate prescription deductibles
- Out-of-network coverage and balance-billing exposure
- Whether copays apply before the deductible
- How family deductibles and maximums work
For 2026, a non-grandfathered family plan with a family out-of-pocket maximum above $10,600 generally needs an embedded individual limit of no more than $10,600. That protects one covered family member from being required to satisfy the larger family maximum alone. HSA-qualified plans also have separate, lower HDHP limits described below.
3. Check 2026 HSA and HDHP Eligibility
A Health Savings Account is available only when you meet the eligibility rules. Merely choosing a plan with a large deductible does not make the plan HSA-qualified.
| 2026 HSA or HDHP rule | Self-only coverage | Family coverage |
|---|---|---|
| HSA contribution limit | $4,400 | $8,750 |
| HDHP minimum deductible | $1,700 | $3,400 |
| HDHP out-of-pocket maximum | $8,500 | $17,000 |
Eligible individuals age 55 or older can generally contribute an additional $1,000. Employer HSA deposits count toward the regular annual contribution limit. If both spouses qualify for catch-up contributions, each spouse generally must make the catch-up contribution to an HSA in that spouse’s own name.
Before contributing, confirm that you are not enrolled in Medicare, covered by a spouse’s general-purpose health FSA, eligible under another disqualifying medical plan, or claimable as another person’s tax dependent. Medicare enrollment can be especially important because retroactive Medicare coverage may affect HSA eligibility for earlier months.
Ask the benefits administrator whether the plan covers telehealth or direct primary care before the deductible and how the arrangement preserves HSA eligibility under the 2026 rules. Rely on the plan’s written confirmation rather than assuming that every telehealth subscription or primary-care membership qualifies.
4. Decide Whether an HSA Fits Your Cash Flow
An HSA can provide valuable federal tax benefits: qualifying contributions may reduce taxable income, earnings can grow tax-deferred, and withdrawals for qualified medical expenses can be tax-free. State tax treatment can differ. The balance rolls over indefinitely, and the account remains yours when you change employers.
Those advantages do not erase the HDHP’s deductible. Compare the following:
- Annual premium savings relative to other plans
- Employer HSA seed or matching contribution
- Expected additional out-of-pocket spending
- Your ability to pay a large bill early in the year
- The cost of your recurring prescriptions and specialist care
Suppose an HDHP saves $2,080 in annual premiums and the employer contributes $1,000 to the HSA. Its initial financial advantage is $3,080. If your projected cost sharing is $2,500 higher than under the PPO, the HDHP may still be competitive. If it exposes you to $5,000 more in likely spending that you cannot comfortably fund, the tax advantages may not make the plan affordable.
Review the HSA provider’s administrative fees, cash-balance or investment threshold, fund selection, investment expenses, transfer rules, and debit-card procedures. If you plan to invest, confirm whether monthly fees or limited funds would materially reduce the benefit.
Do not select an HDHP solely for the tax deduction. Frequent medical care, expensive prescriptions, or tight emergency savings can make its cost-sharing structure difficult even when its long-term HSA features are attractive.
5. Choose an FSA Contribution You Can Actually Use
The 2026 health FSA salary-reduction limit is $3,400, although an employer may set a lower limit. Unlike an HSA, a health FSA is generally intended for near-term spending and may be subject to a use-it-or-lose-it rule.
Your employer may offer either an optional carryover of up to $680 for 2026 or a grace period, but it is not required to offer either feature. Review the plan document instead of assuming unused money will remain available.
Build a conservative contribution estimate
Add predictable eligible expenses such as:
- Medical, dental, vision, and therapy copays
- Prescription medications
- Glasses, contact lenses, and eligible vision supplies
- Planned dental treatment
- Eligible over-the-counter medications and medical products
Use expenses you are reasonably confident will occur. If you expect $1,200 of eligible costs but contribute the full $3,400 without a plan for the difference, the tax savings may be outweighed by forfeited funds.
Check the spending deadline, claim-submission deadline, documentation rules, and what happens to unused funds when employment ends. Although the annual health FSA election is normally available at the beginning of the plan year, reimbursement still depends on eligible expenses and plan procedures.
If you contribute to an HSA, ask whether the employer offers a limited-purpose FSA. This account is generally restricted to eligible dental and vision expenses until any applicable deductible conditions are met, allowing it to operate alongside an HSA.
Review dependent care FSA rules separately
For 2026, the dependent care FSA limit is generally $7,500 per household, or $3,750 for a married person filing separately. This account covers qualifying dependent-care expenses that allow eligible individuals to work or look for work; it is not a medical FSA.
Verify that the provider and type of care qualify, determine when reimbursements become available, and compare the account’s tax benefit with any dependent-care tax credit you may claim. The most favorable choice depends on income, filing status, expenses, and current tax rules.
6. Review Employer Benefits Beyond Medical Insurance
Medical coverage is only one part of the compensation package. Compare employer premium subsidies, HSA funding, FSA administration, wellness incentives, and any credits for completing health assessments or other activities.
- Dental and vision: Review premiums, networks, deductibles, annual benefit maximums, orthodontia coverage, frequency limits, and waiting periods.
- Life insurance: Check employer-paid coverage, supplemental rates, portability, beneficiary designations, and evidence-of-insurability requirements.
- Disability insurance: Compare waiting periods, benefit percentages, maximum payments, coverage duration, and whether benefits may be taxable.
- Mental health and virtual care: Review provider access, visit limits, copays, privacy practices, and whether virtual services are integrated with the medical plan.
- Family support: Evaluate fertility, adoption, caregiver, backup-care, and leave benefits based on their eligibility rules and lifetime limits.
- Other benefits: Consider commuter accounts, legal services, identity protection, employee assistance programs, and voluntary insurance based on actual need.
Confirm any changes to retirement-plan matching, contribution defaults, vesting, or required elections. Review retirement and life-insurance beneficiaries after a marriage, divorce, birth, or death.
Employers may respond to rising 2026 healthcare costs through higher premiums, deductibles, narrower networks, or redesigned benefits. Ask what changed from 2025 and request a side-by-side comparison. A plan with the same name may not have the same network or cost-sharing rules.
7. Complete the Enrollment and Verification Checklist
Before submitting your elections, complete these final steps:
- Save the 2026 plan summaries, rate sheets, provider directories, formularies, and account deadlines.
- Verify dependent eligibility and remove anyone who is no longer eligible.
- Confirm each enrollee’s legal name, date of birth, Social Security number, and coverage election.
- Coordinate your HSA or FSA election with a spouse’s coverage and benefits.
- Check beneficiaries for life insurance, HSAs, and retirement accounts.
- Submit elections before the employer’s stated deadline.
- Save confirmation pages, emails, and confirmation numbers.
If you are comparing employer coverage with a Marketplace plan, use the current Marketplace eligibility calculation. The enhanced federal premium tax credits that applied through 2025 were scheduled to expire after that year, potentially increasing 2026 premiums for affected households. Eligibility also depends on household income, family size, access to affordable employer coverage, and any subsequent federal or state changes.
After coverage begins, inspect the first 2026 pay statement. Confirm the medical, dental, vision, HSA, FSA, life-insurance, disability, and retirement deductions. Also verify that employer HSA funding or other promised credits arrive on schedule. Report discrepancies promptly while enrollment records are easy to retrieve.
What to Do Next
- Forecast your household’s low-, medium-, and high-use healthcare needs.
- Calculate annual premiums and worst-case in-network costs for every plan.
- Confirm provider, hospital, prescription, and HSA eligibility details.
- Choose HSA or FSA contributions based on cash flow and realistic expenses.
- Review the full employer benefits package and document every election.
The best 2026 open enrollment choice is the plan that balances expected costs, financial risk, provider access, and cash-flow needs. Use official plan documents for the final comparison, and consult a qualified benefits, tax, or financial professional when eligibility or tax coordination is unclear.
