How Vistra Employees Can Prepare for the Five “Ghost Taxes” That Could Haunt Retirement

There are several lesser-known surcharges and thresholds that may unexpectedly increase your tax bill in retirement, even if you already understand federal, state, and local tax obligations. These include the Alternative Minimum Tax (AMT), the Net Investment Income Tax (NIIT), the Medicare Income-Related Monthly Adjustment Amount (IRMAA), the Social Security “tax torpedo,” and the new senior deduction. Because many of these thresholds are not adjusted for inflation, they increasingly impact retirees, including those from Vistra.

1. AMT: Alternative Minimum Tax

The AMT is a parallel tax system designed to make sure higher-income individuals pay at least a minimum amount of taxes. It has its own tax brackets, forms, and rules, with a top rate of 28%. ¹ Some deductions available under the traditional tax system are limited under AMT rules.

For 2025, the AMT exemptions are:

- $88,100 for single filers (phasing out at $626,350)
- $137,000 for married couples filing jointly (phasing out at $1,252,700)

High income, exercising incentive stock options, large capital gains, or numerous itemized deductions may trigger AMT. Even though long-term capital gains receive preferential tax treatment, they can still reduce your AMT exemption. If AMT is paid in one year, a tax credit may be available in future years when AMT is not owed.

2. NIIT: Net Investment Income Tax

The NIIT applies a 3.8% tax on net investment income when modified adjusted gross income (MAGI) exceeds:

- $200,000 for single filers
- $250,000 for married couples filing jointly ²

This tax applies to dividends, interest, rental income, gains from home sales, and capital gains beyond exclusion limits. Withdrawals from 401(k)s and traditional IRAs are not directly taxed by NIIT, but they may increase MAGI and cause other investment income to be taxed.

Strategies to limit exposure include contributing to traditional retirement accounts, using health savings accounts (HSAs), and tax-loss harvesting. For instance, tax-loss harvesting allows you to use up to $3,000 in capital losses annually to offset ordinary income. ³

For individuals age 70½ or older looking to reduce MAGI, qualified charitable distributions (QCDs) may help. QCDs allow you to donate to qualified charities on a tax-free basis directly from your IRA, satisfying required minimum distribution (RMD) rules without bringing distributions into income. In 2025, up to $108,000 may be donated tax-free. ⁴

3. IRMAA: Income-Related Monthly Adjustment Amount

IRMAA adds a surcharge to Medicare Parts B and D premiums for higher-income retirees and is based on MAGI from two years prior.

For 2025, IRMAA applies when MAGI exceeds:

- $106,000 for single filers
- $212,000 for married couples filing jointly

Even a small increase above these limits can place retirees in a higher premium bracket. Tax-exempt interest from municipal bonds is included in MAGI for IRMAA purposes. Premiums and IRMAA can be deducted from Social Security payments or paid directly. Social Security allows individuals experiencing major life changes, such as retirement or death of a spouse, to request revised IRMAA calculations.

4. The Social Security “Tax Torpedo”

Social Security benefits may be taxable depending on “provisional income,” which includes:

- Adjusted gross income
- Non-taxable interest
- One-half of Social Security benefits

If provisional income exceeds:

- $34,000 for single filers
- $44,000 for married couples filing jointly

...then up to 85% of Social Security benefits may be taxable. ⁵

Delaying Social Security up to age 70 increases benefits by 8% per year beyond full retirement age.

5. The 2025–2028 New Senior Deduction

From 2025 to 2028, individuals age 65 and older may qualify for a new senior deduction:

- $6,000 for single filers
- $12,000 for married couples filing jointly

This deduction phases out at:

- $75,000 MAGI for single filers
- $150,000 MAGI for joint filers

This is separate from the standard senior deduction, which currently adds $2,000 for individuals or $3,200 for married couples age 65 or older.

Eligibility Criteria for Represented and Non-Represented Employees: The Vistra Operations Company pension plan has distinct eligibility criteria for represented and non-represented employees. Non-represented employees hired or rehired on or after January 1, 2019, are not eligible to participate in the plan, as their benefits were frozen effective December 31, 2018.

What steps should an employee at Vistra Operations Company take if they wish to contest a denial of benefits they believe they are entitled to under the plan? Please outline the procedures outlined in the document that the employees must follow to ensure their rights under the Employee Retirement Income Security Act are upheld.

Contesting a Denial of Benefits: Employees must file a written claim for benefits if they believe they were denied benefits under the plan.

What factors specific to their circumstances and relation to the plan should they consider, such as marital status or previous employment benefits?

Options for Employees Nearing Retirement: Employees nearing retirement have several options for receiving their pension benefits, including single life annuity or joint and survivor annuity payments.

In what ways does the Vistra Operations Company pension plan accommodate employees transitioning from another employer's retirement plan, particularly with frozen benefits under an acquired plan? Employees should consider how these changes could impact their retirement outcomes and what steps are needed to integrate these benefits.

Transitioning from Another Employer’s Retirement Plan: Employees who transition from another employer’s retirement plan, especially those whose benefits have been frozen under an acquired plan, may still be eligible for interest credits on their account balances. The plan allows these employees to continue receiving interest credits while their account remains in the plan, preserving the value of their retirement savings(Vistra_Operations_Compa…)(Vistra_Operations_Compa…).

How can employees of Vistra Operations Company name a beneficiary in relation to their retirement benefits, and what specific requirements must be met to ensure that the designation is legally valid? Discuss the implications for both the employees and their chosen beneficiaries, including any necessary consents or notarizations.

Naming a Beneficiary: Employees can designate a beneficiary for their pension benefits, and if they are married, their spouse must provide notarized consent if they choose someone else as their beneficiary. It is important to update this information following life changes, such as marriage or divorce, to ensure benefits are distributed according to their wishes(Vistra_Operations_Compa…).

What provisions are in place within the Vistra Operations Company pension plan for employees who become disabled before reaching retirement age? Employees should understand how disability benefits interact with their retirement benefits and what criteria they must meet to access these provisions.

Annual Interest Crediting Rate: For defined benefit plans, the interest crediting rate is based on the 30-year Treasury securities rate, which can affect employees’ retirement savings. Represented employees may be subject to minimum interest credit rates depending on their collective bargaining agreements, while non-represented employees' interest credits continue even after benefits were frozen(Vistra_Operations_Compa…).

What are the implications of being classified as a non-represented employee under the Viesta Operations Company pension plan, especially considering the plan was frozen for them starting January 1, 2019? Employees should evaluate how this classification impacts their retirement planning and options moving forward.

Impact of Being a Non-Represented Employee: Non-represented employees had their benefits frozen as of December 31, 2018. This freeze means they no longer accrue new benefits, but they may still receive interest credits on their existing frozen benefit. Employees in this classification should evaluate alternative retirement savings options moving forward(Vistra_Operations_Compa…).

Could you explain the importance of the â€œnormal retirement ageâ€ and how it affects the pension benefits for participants in the Vistra Operations Company pension plan? Illustrate how this age plays a significant role in defining eligibility and benefit calculations.

Importance of "Normal Retirement Age": The normal retirement age under the plan is 65. This age is critical because it affects when employees become eligible for their full pension benefits without reduction, which plays a significant role in the calculation and payment of benefits(Vistra_Operations_Compa…).
