Are Ghost Taxes Creeping Into Your Berkshire hathaway Retirement Plan?

Healthcare Provider Update: Healthcare Provider for Berkshire Hathaway: UnitedHealth Group Blog Post Paragraph on Potential Healthcare Cost Increases in 2026: As we look toward 2026, Berkshire Hathaway employees and many others in the United States may face significant challenges with healthcare costs. Current projections indicate that average premiums for Affordable Care Act (ACA) marketplace plans could rise sharply, with some states experiencing increases of over 60%. This surge is largely attributed to the possible expiration of enhanced federal subsidies, alongside escalating medical costs driven by factors such as expensive medications and hospital services. Experts warn that without renewed subsidies, millions of consumers could see their premiums more than double, putting healthcare access at risk for a substantial portion of the population.

How Berkshire hathaway 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 Berkshire hathaway.

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.

How does the merger of the Johns Manville Employees Retirement Plan into the Berkshire Hathaway Consolidated Pension Plan specifically affect the retirement benefits for current employees at Johns Manville? In what ways can eligible employees of Johns Manville leverage the benefits of this merger to maximize their retirement planning?

Impact of Merger on Current Employees' Retirement Benefits: The merger of the Johns Manville Employees Retirement Plan into the Berkshire Hathaway Consolidated Pension Plan does not decrease the pension benefits previously earned by employees under their prior plans. Employees continue to receive the same benefits with the same payment options as provided by their prior plan. Any previous payment elections, beneficiary designations, and qualified domestic relations orders remain effective. This consolidation also maintains the insurance of pension benefits through the federal Pension Benefit Guaranty Corporation.

What are the implications for employees of Johns Manville if they choose to retire early prior to their Normal Retirement Age? How do the specific conditions set forth in the Berkshire Hathaway Consolidated Pension Plan guide early retirees from Johns Manville in making informed decisions regarding their benefit options?

Implications of Early Retirement: Employees of Johns Manville who choose to retire early, before their Normal Retirement Age, can still receive benefits. However, these benefits are adjusted based on the age of retirement. If an employee retires at 60, for instance, their monthly benefit payment from the plan will be reduced by a certain percentage for each month that the benefit payments start before the Normal Retirement Age. This reduction compensates for the longer period over which benefits are expected to be paid.

Additionally, how is Covered Compensation factored into this adjustment, and what strategies can employees employ to ensure accurate calculations?

Calculation of Average Final Salary and Covered Compensation: When calculating the Average Final Salary for retirement benefits, it includes the highest-paid, five consecutive years out of the last ten years of employment. This calculation impacts the retirement benefits as it forms part of the formula used to determine the pension amount. Additionally, Covered Compensation, which refers to the average of the Social Security wage bases, is used to adjust portions of the salary in the benefits calculation, ensuring that the benefits align with national wage growth trends.

How can employees of Johns Manville navigate the various options available for retirement benefit payments outlined in the Berkshire Hathaway Consolidated Pension Plan? What key points should Johns Manville employees consider regarding the selection of forms of payment and potential tax implications in retirement?

Navigating Retirement Benefit Payment Options: Employees of Johns Manville need to consider the form of payment for their retirement benefits, as different options can have different tax implications and affect monthly income. Options typically include lump sums, annuities, or a combination. Employees should consider their financial needs, tax situation, and life expectancy when choosing the form of payment. Consulting with a financial advisor could be beneficial.

For employees at Johns Manville, what steps should they take to stay informed about their accumulated service and benefit service credits, particularly in relation to the changes brought about by the merger into the Berkshire Hathaway Consolidated Pension Plan? How do vested rights impact their eligibility for retirement benefits?

Staying Informed About Service Credits: To manage the transition and keep track of their service credits post-merger, Johns Manville employees should regularly review their service and benefit statements, maintain communication with the plan administrator, and attend any informational meetings or seminars offered by Berkshire Hathaway. Understanding how service credits are calculated and tracked ensures that employees can accurately plan for retirement.

What is the process for reemployment under the Terms of the Merged Plan for former employees of Johns Manville, and how can they ensure their accumulated benefit service is credited effectively upon rehire? What are the implications of this reemployment on their retirement benefits, particularly concerning their previous employment history?

Reemployment and Accumulated Benefits: Reemployed former employees of Johns Manville should verify how their accumulated benefits are treated upon their rehire. Generally, benefits accumulated during previous periods of employment will be credited upon rehire, but specific plan provisions should be consulted to confirm how reemployment affects accrued benefits and eligibility for additional benefits.

What do the terms of the Berkshire Hathaway Consolidated Pension Plan dictate regarding disability retirement benefits for eligible employees at Johns Manville? How should employees approach the application process for disability benefits, and what criteria do they need to be aware of to qualify?

Disability Retirement Benefits: Eligible employees of Johns Manville who become disabled according to the terms of the plan may qualify for disability retirement benefits. The process involves a determination by the plan administrator, and employees must meet specific criteria outlined in the plan documents to qualify. Understanding these criteria and the required documentation is crucial for accessing disability benefits.

How can employees of Johns Manville ensure they have adequate protection for their beneficiaries under the retirement provisions outlined in the Berkshire Hathaway Consolidated Pension Plan? What specific steps can employees take to secure these benefits, and how can they keep their beneficiary designations updated?

Beneficiary Protections: Employees should regularly review and update their beneficiary designations to ensure that their retirement benefits are distributed according to their wishes upon their death. This includes making any necessary changes following life events such as marriage, divorce, or the birth of a child.

How does participation in the Merged Plan differ for salaried and hourly employees of Johns Manville, and what specific eligibility criteria apply to each group? How can understanding these differences improve retirement planning for employees across the different classifications?

Differences in Participation for Salaried and Hourly Employees: The eligibility and benefits might differ between salaried and hourly employees under the Merged Plan. Understanding these differences helps employees make informed decisions about their retirement planning and benefit utilization.

How can employees of Johns Manville contact the Local Benefits Administrator for assistance regarding their retirement benefits and the contents of their plan documents? What are the recommended methods of communication for inquiries or requests regarding their Merged Plan benefits?

Contacting Local Benefits Administrator: Employees should contact their Local Benefits Administrator for any inquiries or assistance regarding their retirement plan.
