How CITGO 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 CITGO.

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.

Understanding how AMT, NIIT, IRMAA, Social Security rules, and senior deductions affect retirement income can be complex, especially for CITGO retirees managing pensions, 401(k)s, and other investments.

What are the eligibility criteria for employees to participate in the Retirement Plan of CITGO Petroleum Corporation, and how do these criteria affect the benefits that employees accrue? Employees of CITGO Petroleum Corporation must meet specific criteria to qualify for the Retirement Plan, which is designed to provide a stable income during retirement. Understanding these eligibility requirements is crucial for employees, as it impacts their expected benefits and retirement strategy.

Eligibility for the CITGO Petroleum Corporation Retirement Plan: Employees must be at least 21 years old and have completed 12 months of employment with at least 1,000 hours of service to be eligible. Hourly employees covered by a collective bargaining agreement are typically included after meeting these requirements. Eligibility significantly affects benefits accrual, as being a participant allows employees to begin accruing service and vesting credits, which directly influence retirement benefit calculations(CITGO_Petroleum_Corpora…).

How does the Cash Balance Benefit structure work within the Retirement Plan of CITGO Petroleum Corporation, particularly regarding the accumulation of Compensation Credits and Interest Credits? The Cash Balance Benefits offer a valuable retirement savings mechanism for CITGO employees, impacted by their Basic Earnings and years of service. As interest rates fluctuate, the manner in which these credits accumulate can significantly influence the overall retirement benefit.

Cash Balance Benefit Structure: The Cash Balance Benefit under the Retirement Plan includes Compensation Credits and Interest Credits. Compensation Credits are based on a percentage of Basic Earnings, determined by the employee's age and years of service. Interest Credits are applied annually and are calculated based on the higher of the 30-year Treasury securities rate or 1.5%. These credits are added to the employee's notional account balance each year, with the total balance used to determine the retirement benefit(CITGO_Petroleum_Corpora…).

In what ways can employees of CITGO Petroleum Corporation manage their Frozen Accrued Benefit upon retirement, and what considerations must they take into account? Employees nearing retirement should know how to optimize their Frozen Accrued Benefit for their individual retirement planning. Factors such as timing, potential changes in personal circumstances, and regulatory aspects play a critical role in this planning process.

Managing Frozen Accrued Benefits: Upon retirement, employees can manage their Frozen Accrued Benefit by selecting different payout options such as a single-life annuity or joint and survivor annuities. The timing of retirement also plays a key role, as early retirement may reduce the benefits based on age reduction factors. Employees need to consider their financial circumstances and retirement goals to optimize this benefit(CITGO_Petroleum_Corpora…).

What are the implications of transferring employment status (from hourly to salaried) on participation in the Retirement Plan of CITGO Petroleum Corporation? Understanding how a transition from hourly to salaried employment affects fund accumulation and credit service under the Retirement Plan is vital for employees planning their careers. Such transitions need to be handled carefully to ensure that benefits remain maximized.

Effect of Employment Status Transfer: A transfer from hourly to salaried employment will freeze Benefit Credit Service under the Plan, but Vesting Credit Service continues. Compensation and Transition Credits cease for hourly employees transitioning to salaried roles. However, Interest Credits continue until the Cash Balance Benefit is distributed. These changes can affect the overall retirement fund accumulation(CITGO_Petroleum_Corpora…).

How do various retirement benefit options, including lump-sum payments and annuities, function within the CITGO Petroleum Corporation Retirement Plan? Employees face various choices regarding the disbursement of retirement benefits, each carrying unique financial implications. Evaluating these options requires a keen understanding of how they interact with overarching financial goals.

Retirement Benefit Options: CITGO Petroleum employees can choose between receiving their retirement benefits as a lump sum or through an annuity. Each option has different financial implications. Lump-sum payments offer immediate access to funds, but annuities provide a steady income stream over the retiree's lifetime. The choice between these options depends on the employee’s personal financial strategy(CITGO_Petroleum_Corpora…).

What is the role of the Plan Administrator in resolving benefits-related issues for employees at CITGO Petroleum Corporation, and how can employees effectively interact with this office? Employees must understand the administrative structure governing their retirement benefits. Effective communication with the Plan Administrator can significantly enhance an employee's ability to navigate complex issues regarding their retirement.

Role of Plan Administrator: The Plan Administrator is responsible for managing and resolving any issues related to retirement benefits. Employees can contact the Benefits HelpLine for inquiries or disputes regarding their benefits. Effective communication with the Plan Administrator ensures that employees can navigate and resolve issues related to their retirement plan(CITGO_Petroleum_Corpora…).

How does the vesting schedule impact the retirement benefits of employees at CITGO Petroleum Corporation, and what strategies can employees employ to ensure full vesting? The vesting schedule is a critical component influencing when employees become entitled to their benefits. Employees should be aware of what actions can enhance their vesting status prior to retirement.

Impact of the Vesting Schedule: CITGO’s vesting schedule requires employees to have at least three years of service to become 100% vested. Vesting entitles employees to receive full benefits under the Plan. Employees nearing retirement should ensure they meet the vesting requirements to maximize their entitled benefits(CITGO_Petroleum_Corpora…).

What are the special provisions that exist for employees returning to work after receiving retirement benefits within the CITGO Petroleum Corporation Retirement Plan? Employees considering retirement must appreciate how returning to work can alter their benefits under the Retirement Plan. The potential effects on benefit payments, roles, and rights are crucial discussions for retiring employees.

Returning to Work Post-Retirement: Employees who return to work after receiving retirement benefits will have their benefit payments suspended. Upon re-retirement, their benefits are recalculated to reflect any additional service accrued during reemployment. Employees must understand these provisions to avoid potential disruptions to their retirement income(CITGO_Petroleum_Corpora…).

How is the funding status of the Retirement Plan of CITGO Petroleum Corporation determined, and what implications does it have for current and future benefits? The viability of the Retirement Plan is heavily influenced by its funding status, impacting all participants. Employees should stay informed about what underpins this status and how it may affect their own long-term retirement planning.

Plan Funding Status: The funding status of the Retirement Plan is essential, as it affects the availability of lump-sum payments and may influence future benefits. Employees should monitor the Plan’s funding status to understand how it impacts their options and the security of their retirement benefits(CITGO_Petroleum_Corpora…).

How can employees of CITGO Petroleum Corporation obtain further information about their retirement benefits, and what specific resources are available to assist them?
