Phillips 66 Employees: Preparing for the 2026 Social Security COLA Increase

Healthcare Provider Update: Healthcare Provider for Phillips 66 Phillips 66 offers healthcare coverage through multiple providers, primarily Aetna and Blue Cross Blue Shield (BCBS), depending on the employee's home ZIP code. Employees also have access to a Kaiser HMO option if they live in designated areas of California or Washington. The medical plans include comprehensive coverage for various healthcare services, including preventive care, regular checkups, mental health, and substance use disorder treatments. Potential Healthcare Cost Increases in 2026 Healthcare costs for Phillips 66 employees can be expected to rise significantly in 2026, reflecting broader trends impacting the Affordable Care Act (ACA) marketplace. As major insurers are filing for rate increases that may exceed 60% in certain states, Phillips 66 employees could face steep hikes in out-of-pocket premiums, especially if federal subsidies are not extended. The combination of escalating medical costs and the potential loss of enhanced subsidies means many employees may see their premium costs increase substantially, leaving them with difficult choices regarding their healthcare coverage amidst these changing economic conditions.

'While the Social Security COLA boost may offer added income for Phillips 66 employees entering retirement, it’s important to plan carefully, as higher benefits can also raise taxable income over time.'—Patrick Ray, a representative of The Retirement Group, a division of Wealth Enhancement.

In this article, we will discuss:

1. How the 2026 Social Security cost-of-living adjustment (COLA) impacts Phillips 66 retirees.

2. Tax implications of higher Social Security benefits and ways to manage them.

3. Timing strategies for Social Security benefits and available deductions for retirees.

What Phillips 66 Retirees Need to Know About Social Security COLA 2026

The Social Security cost-of-living adjustment (COLA) for 2026 is set at 2.8%, slightly higher than the previous year’s 2.5% increase. ¹  This annual COLA, announced by the Social Security Administration (SSA) in October and applied to January benefits, helps retirees maintain purchasing power during inflationary periods. For Phillips 66 employees nearing or in retirement, this adjustment can play a key role in income planning.

According to the Bureau of Labor Statistics, the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W)—which determines COLA—increased 3% over the 12 months ending September 2025. ²

While this is lower than the 8.7% increase in 2023, ³  it may still offer meaningful relief to Phillips 66 retirees experiencing higher living expenses.

How Higher Benefits Could Affect Taxes

As Social Security benefits rise, your combined (or “provisional”) income may increase, which can cause a greater portion of your benefits to be taxed. Combined income includes wages, pensions, interest, dividends, taxable withdrawals from traditional 401(k)s or IRAs, non-taxable interest, and half of your Social Security benefits. 

For single filers with income below $25,000 and joint filers below $32,000, Social Security benefits are not taxed. Between $25,000 and $34,000 for single filers and $32,000 and $44,000 for joint filers, up to 50% of benefits may be taxable. Income above those ranges can result in up to 85% of benefits being taxable. ³  These income thresholds are not adjusted for inflation, which means Phillips 66 retirees may experience increased taxation over time as income rises.

Withdrawals from traditional Phillips 66 retirement plans, such as 401(k)s and IRAs, are treated as ordinary income and can increase the taxable portion of Social Security benefits. Thoughtful timing of withdrawals may help manage tax exposure.

Strategies to Manage Tax Impact

If rising taxes are a concern, the following strategies may help:

• Balance withdrawals across account types.  Coordinating distributions from tax-deferred, taxable, and Roth accounts may help you meet required minimum distribution (RMD) rules while managing your tax bracket.

• Use taxable accounts strategically.  Only capital gains—not your initial investment—are taxable.

• Consider tax-free withdrawals.  Qualified distributions from Roth IRAs, Roth 401(k)s, or Health Savings Accounts (HSAs) are not included in taxable income and do not affect Social Security taxation.

New Senior Tax Deduction: 2025–2028

Beginning in 2025, a new senior deduction of $6,000 per person ($12,000 for joint filers) will be available to taxpayers age 65 and older. This deduction phases out at $75,000 adjusted gross income (AGI) for single filers and $150,000 for joint filers. 

This deduction is in addition to the age-65+ standard deduction increase of $2,000 for single filers and $1,600 per eligible spouse for joint filers in 2025. Phillips 66 retirees may wish to include this in long-term tax planning.

Timing Your Social Security Benefits

Delaying Social Security until full retirement age (67) or up to age 70 generally results in higher lifetime benefits. Benefits increase by about 8% for each year you delay claiming between your full retirement age and age 70. 

For Phillips 66 retirees, delaying benefits may provide additional flexibility in coordinating income from pensions, savings, or retiree medical accounts.

Social Security provides inflation-adjusted income for life, which may contribute to financial stability when aligned with corporate retirement benefits.

Keep the Big Picture in Mind

While the 2026 COLA helps counter rising costs, it can also raise taxable income for some retirees. Thoughtful planning around withdrawals, deductions, and timing of benefits can help manage long-term taxes. Because tax laws are complex, developing a multi-year strategy with a financial advisor is recommended.
