'Alliant Energy employees approaching retirement should recognize that proactive income and health care planning can make the difference between preserving subsidy eligibility and facing sharply higher ACA premiums.' – Paul Bergeron, a representative of The Retirement Group, a division of Wealth Enhancement.
In this article, we will discuss:

How the expiration of enhanced ACA subsidies after 2025 could impact health care costs for retirees and early retirees.

Real-life case studies illustrating how different individuals are adjusting to rising ACA premiums.

Practical steps Alliant Energy professionals can take before enrolling in 2026 Marketplace plans.
by Brent Wolf, CFP®, Wealth Enhancement
As open enrollment for 2026 Marketplace plans begins, many households are seeing dramatic shifts in their renewal letters. Rising base premiums and the possible end of enhanced subsidies after 2025 could mean significantly higher out-of-pocket costs for anyone purchasing coverage through the Affordable Care Act (ACA) exchange.
The Kaiser Family Foundation (KFF) estimates that if Congress does not extend enhanced premium tax credits, average net premium payments could more than double in 2026. 1
“It feels like a second mortgage to pay this premium.”
Profile: A couple in their early 60s who retired a few years before becoming Medicare-eligible.
What changed: Their ACA premium had been manageable due to increased subsidies. Their renewal now indicates a rise of about $1,000 to $1,200 monthly if enhanced credits expire.
Decision pressure: They faced hard choices—drawing more taxable income from IRAs, going without coverage, or returning to the workforce for employer-based insurance.
Our response: We reworked their income plan to align with the ACA’s income-based subsidy structure. By controlling their Modified Adjusted Gross Income (MAGI) through smaller IRA withdrawals, use of cash reserves, and partial Roth conversions, we kept them eligible for key subsidies. Comparing a Bronze high-deductible plan with a health savings account (HSA) to a Silver plan revealed the Silver plan—thanks to cost-sharing reductions—was more economical given their expected medical treatments.
“I can’t risk losing coverage while battling an illness.”
Profile: A single client in her early 60s undergoing ongoing medical treatment.
What changed: Without enhanced subsidies, her premiums nearly tripled.
Decision pressure: Balancing affordability with the need to keep her care team and prescriptions consistent.
Our response: We prioritized staying with her provider network and controlling her out-of-pocket costs. A dedicated “medical reserve” fund—equal to one year’s maximum out-of-pocket limit—gave her a cushion without liquidating investments during market declines. We also worked with her physicians to identify lower-cost prescriptions through her plan’s formulary.
“The new premiums are hurting our business margins.”
Profile: A self-employed couple—one partner managing asthma and the other a cardiac rhythm condition.
What changed: Without subsidies, their net premiums are expected to rise sharply.
Decision pressure: Continue paying high premiums, choose a plan with a very high deductible, or seek W-2 employment for benefits.
Our response: We compared total annual costs for a Silver plan versus a Bronze option, factoring in frequent specialist visits and prescriptions. Once total medical costs were considered, the Silver plan proved more cost-effective. We also aligned their life and disability coverage and tailored their tax approach to reflect potential changes in premium tax credits.
“I’m young and healthy—do I even need full coverage?”
Profile: An independent contractor in their 20s with minimal expected medical use.
What changed: Premiums for mid- and high-tier plans nearly quadrupled.
Decision pressure: Choosing between a high-deductible Bronze HSA plan and catastrophic coverage.
Our response: We modeled three options—a Bronze HSA-eligible plan, a mid-tier plan, and catastrophic coverage. The Bronze HSA option offered the best mix of lower premiums and long-term tax benefits. Monthly automated HSA contributions build a future medical fund that can later be used for qualified health care expenses or Medicare premiums (excluding Medigap) after age 65.
Five Steps to Take Before You Enroll
1. Evaluate your total annual cost, not just the premium. Factor in deductibles, copays, and the possibility of reaching your out-of-pocket maximum.
2. Manage your MAGI carefully. ACA subsidies depend on income. Coordinate Roth conversions, capital gains, and IRA withdrawals strategically.
3. Verify your doctor and prescription coverage. Always confirm your plan’s provider network and formulary before enrolling.
4. Maintain a medical reserve fund. Hold six to 12 months of premiums plus a portion of your maximum out-of-pocket in cash or short-term Treasuries.
5. Finalize your plan by December 15. Open Enrollment for 2026 coverage ends on December 15, with plans effective January 1.
If Affordability Is a Concern
Choosing to go without insurance can expose you to serious financial strain in case of illness or accident. Consider the most affordable Bronze plan that still meets ACA minimum coverage requirements. If your income decreases during the year, you may become eligible for Medicaid or CHIP and qualify for a Special Enrollment Period. 2

Alliant Energy offers its employees both a defined benefit pension plan and a 401(k) plan as part of their retirement benefits package. The company's pension plan follows a Final Average Pay (FAP) formula, where benefits are calculated based on the average salary over the final years of an employee's career, multiplied by years of service. Employees become vested in the pension plan after a specified number of years of service, generally after 10 years. Alliant Energy's defined benefit plan ensures that employees who retire at the standard retirement age of 65 or older receive a monthly pension payment, with earlier retirements receiving adjusted, reduced benefits (Pension Rights Center) (Wikipedia) (Wikipedia).
Alliant Energy's 401(k) plan allows employees to contribute a percentage of their income to a tax-deferred savings account. The company matches a portion of employee contributions, a common feature to incentivize savings. Employees have the option to choose between traditional 401(k) contributions, which are made pre-tax, and Roth 401(k) contributions, made after-tax. These plans also provide a wide range of investment options, such as mutual funds, bonds, and stocks, which employees can select based on their retirement goals (Wikipedia) (Annuity.org).
In terms of eligibility, employees generally qualify for both the pension plan and the 401(k) plan after meeting a specific threshold of years of service, which is typically 10 years for the pension plan and immediate eligibility for the 401(k) plan upon employment. The pension benefits calculation typically involves age and years of service. As for the 401(k), employees can enroll upon hire and take advantage of Alliant Energy's employer matching contribution immediately.
In 2024, Alliant Energy continued its energy transition efforts by filing a request to convert its coal-fueled Edgewater Generating Station to natural gas. This shift is part of Alliant's broader sustainability initiatives aimed at reducing greenhouse gas emissions and bolstering reliability (Homepage). The company reaffirmed its commitment to clean energy and community economic benefits. This restructuring is crucial to track because the energy industry is directly influenced by shifts in the economic and political landscape, which has implications for investment strategies and tax benefits (Alliant Energy Retirees - Home) (Alliant Energy Retirees - Home).
Alliant Energy updated its 401(k) plan record keeper in 2023, switching to Fidelity Investments. This transition, disclosed in an 8-K filing with the SEC, signifies an effort to enhance the management and performance of employee retirement plans (Alliant Energy Retirees - Home). Changes in company benefits and pensions are essential to follow because they reflect how companies are adapting to both market conditions and new tax laws, affecting employees' retirement security (Alliant Energy Retirees - Home).
Alliant Energy offers its employees stock options (SO) and Restricted Stock Units (RSU) as part of its compensation and benefits program. Stock options provide employees the right to purchase company stock at a predetermined price, while RSUs are company shares granted to employees, typically with vesting conditions. Alliant Energy's stock options and RSUs are generally made available to senior-level management and eligible employees based on performance and tenure.
In 2022, Alliant Energy continued to grant stock options under its Long-Term Incentive Plan (LTIP). These stock options (LNT-SO) allowed eligible employees to purchase shares at a set price, aligning their interests with shareholder value growth. Additionally, RSUs (LNT-RSU) were awarded, vesting over time as an incentive to retain talent and reward long-term contributions (Homepage) (Alliant Energy) (Homepage).
For 2023 and 2024, the company sustained its stock option grants, especially focusing on performance-based RSUs, which required meeting specific performance metrics for full vesting. These RSUs are typically granted annually and can vest over several years, incentivizing executives and employees to meet long-term company goals. Information on the distribution and conditions for these awards can be found in Alliant Energy’s annual reports and proxy filings.
Alliant Energy offers comprehensive health benefits to its employees and retirees, reflecting a commitment to supporting the well-being of their workforce. For current employees, the company provides several key healthcare options, including medical, dental, and vision insurance plans. Their health plans emphasize flexibility and affordability, with options such as the Consumer-Driven Health Plan (CDHP), which allows employees to manage their healthcare expenses using Health Reimbursement Arrangements (HRA) and Flexible Spending Accounts (FSA). Additionally, Alliant Energy provides access to mental health services through their Employee Assistance Program (EAP), which offers confidential support for personal, emotional, and financial issues (Alliant) (Homepage).
The importance of discussing healthcare benefits at Alliant Energy in today's economic, investment, and political environment cannot be overstated. Rising healthcare costs and changing tax laws have made it critical for employees to maximize their benefits, especially as companies like Alliant Energy continue to adapt their offerings to provide sustainable and inclusive coverage. For retirees, Alliant Energy ensures continuity in care through early retiree medical benefits, with premium categories based on contract status. With programs such as Delta Dental and VSP for vision care, the company maintains comprehensive coverage even after retirement. As healthcare remains a significant concern in policy debates, understanding these benefits helps employees and retirees alike plan for future costs and healthcare needs.
