Open Enrollment Guide to Employee Benefits Planning

Jeff Weeks, CFP® (Certified Financial Planner™) | ATX Portfolio Advisors | The Accountable Update

Did you spend more time picking your last vacation rental than choosing your employee benefits? Annual enrollment may not be anyone’s idea of a good time, but it deserves more than a speed run through the human resources portal. Those choices help determine how your household handles medical expenses, lost income, taxes, and retirement savings.

The planning challenge is that employers present benefits one election at a time, while families experience the consequences together. A health plan affects the emergency reserve. A spouse’s benefits can change which tax accounts are available. The most useful review connects those decisions to the household’s financial plan.

1. Compare the Full Cost of Health Coverage

I would begin with the Summary of Benefits and Coverage for each available plan, then verify the provider network and prescription coverage. Compare annual employee premiums, expected medical expenses, employer health savings account (HSA) funding, and the applicable maximum for covered care within the network. Check how individual and family deductibles work. A lower premium has limited appeal if an important specialist or medication becomes substantially more expensive.

Consider a simplified hypothetical. Plan A costs $6,000 annually in premiums, has an $8,000 family spending maximum within the network, and provides $1,500 in employer HSA funding. Plan B costs $9,000 in premiums, has a $5,000 family spending maximum, and provides no account funding. In a year when the family reaches each maximum, the combined cost is $12,500 for Plan A after employer funding and $14,000 for Plan B, before tax effects.

That calculation is a starting point. Premiums, excluded services, and some care outside the network can create expenses beyond the stated spending maximum. The timing matters, too: a deductible due in January may arrive before much employer funding. I would compare a routine year, a year with known treatment, and a high-spending year, then confirm that cash reserves support the choice.

2. Invest the Health Savings Account for Future Expenses

For 2027, HSA contribution limits are $4,500 for individual coverage and $9,000 for family coverage, including employer deposits. Eligible people age 55 or older can add $1,000. Each spouse’s additional contribution must go into that spouse’s own account.

I would put the HSA in the running for the most tax-favored investment vehicle available under federal law. Eligible payroll contributions through an employer’s cafeteria plan generally avoid federal income tax and Federal Insurance Contributions Act (FICA) taxes, which fund Social Security and Medicare. Investment growth and withdrawals for qualified medical expenses are also federally tax-free. Direct personal contributions generally provide an income tax deduction but do not recover FICA taxes already paid.

For households that can comfortably pay current medical bills from other resources, the strategy is to contribute, invest the HSA for long-term growth, and save receipts instead of immediately withdrawing the money. Keep a durable digital record of itemized bills, proof of payment, and reimbursement history. Federal rules impose no time limit for reimbursing qualifying expenses incurred after the account was established, provided they were not previously reimbursed or claimed as a tax deduction. Those records can support tax-free withdrawals years later while the invested balance has had time to compound.

Eligibility and liquidity still matter. A spouse’s general purpose health flexible spending arrangement (FSA) can block HSA contributions if it covers your expenses; an appropriately designed limited purpose FSA may be compatible. Medicare enrollment and an existing FSA can also affect eligibility. Invest according to your time horizon and risk tolerance, keeping enough accessible for anticipated bills rather than borrowing to preserve an invested balance.

3. Size Spending Accounts to Expenses You Can Predict

A health FSA works best when the contribution reflects expenses you reasonably expect to incur. Review prescriptions, dental treatment, vision care, and scheduled procedures, along with the plan’s spending and claim deadlines. Unused balances generally face forfeiture, although a plan may offer a permitted carryover or grace period. An election based on the maximum allowance can leave money stranded.

Dependent care deserves a separate calculation. Beginning in 2026, the federal exclusion increased to $7,500, or $3,750 for married taxpayers filing separately, but the employer’s plan may allow less. Coordinate both spouses’ elections, employer contributions, work eligibility, and expected qualifying care costs. Compare the exclusion with the dependent care tax credit under the applicable year’s rules; excluded benefits reduce the expenses available for that credit.

4. Protect the Income Supporting the Plan

Disability coverage may have more influence on a working family’s financial security than several smaller benefit elections combined. Review the monthly benefit cap, waiting period, definition of disability, benefit duration, and treatment of bonuses or commissions. Then estimate the amount actually available for household expenses. A percentage of salary can sound sufficient until the policy’s cap and taxes are applied.

Benefits attributable to employer-paid premiums or premiums paid through a cafeteria plan generally are taxable. Benefits from coverage you pay for entirely with money already taxed generally are not. That distinction changes the income replacement calculation. Life insurance needs a similar review of the actual dollar amount, dependents’ needs, existing assets, underwriting requirements, and what happens to coverage when employment ends.

5. Explore the Mega Backdoor Roth 401(k)

Start with the contribution needed for the full employer match, then ask whether the plan supports a Mega Backdoor Roth 401(k). This strategy can move substantially more retirement savings into Roth accounts than the regular employee deferral limit alone allows. It requires the plan to permit additional, non Roth after tax employee contributions and a way to move them into Roth accounts.

Depending on the plan, that route is a conversion to the Roth account inside the 401(k) or an eligible distribution while still employed that can be rolled into a Roth individual retirement account (IRA). Regular employee deferrals apart from catch-up contributions, along with employer contributions, use part of the overall annual contribution limit; eligible after-tax contributions can use the remaining room, subject to plan restrictions and testing. Simply selecting “Roth” for your regular payroll contribution does not activate this strategy.

Ask whether conversions can occur automatically or frequently. Moving the after-tax contributions promptly can limit taxable earnings accumulated before conversion; those contributions themselves are not taxed again, while associated pretax earnings moved to Roth generally are taxable. A properly implemented Mega Backdoor Roth can be especially useful for higher earners who have additional saving capacity, with future qualified Roth withdrawals free of federal income tax. Confirm the mechanics and any taxes before changing payroll elections.

Also review the regular pretax versus Roth election and whether contributing heavily early could cost you later payroll matches. Certain higher-earning employees eligible for catch-up contributions must use Roth for those catch-ups under the rule that began in 2026. Confirm the applicable prior year wage threshold, the coming year’s limits, and payroll treatment. These decisions belong in the household tax and cash flow plan.

6. Weigh Stock Awards and Deferred Compensation Against Employer Risk

Restricted stock units (RSUs), an employee stock purchase plan, and nonqualified deferred compensation can be valuable benefits, but each adds a different exposure to the employer. RSUs typically deliver shares as they vest and settle, with their value generally recognized as compensation income when delivered. Review the vesting schedule, tax withholding, sale restrictions, and how much employer stock would accumulate if you keep every award. Include unvested awards when assessing future dependence on the company, while recognizing that they remain conditional.

Once shares are available to sell, I would consider this question: If the company paid the same amount in cash, would you use it to buy its stock? Keeping the shares is an investment decision with the same concentration risk. A stock purchase discount can also be attractive without making indefinite ownership the best choice. Coordinate purchases and sales with taxes, trading restrictions, liquidity needs, and a diversification policy across all employer shares.

Nonqualified deferred compensation may postpone income and help manage future taxes but generally involves an unsecured promise from the employer. Review election deadlines, payment dates, consequences of leaving, and the company’s ability to pay. Consider that exposure alongside your salary, unvested RSUs, and stock holdings. The planning question is whether the combined benefits justify having more of the family’s financial future depend on one company.

7. Confirm the Elections and Update the Plan

Before submitting, compare both spouses’ benefit packages and confirm covered dependents, beneficiary designations, and any evidence of insurability required. Save the election confirmation and check the first applicable payroll deductions. Feed the results back into the household budget, emergency reserve, insurance analysis, and retirement projections. A completed enrollment screen is useful only when the intended coverage and contributions actually take effect.

As an Austin financial planner, I would use enrollment season to bring those connections into focus. The goal is to choose benefits that support the family’s priorities and remain workable when expenses or employment change.
