Moving for Retirement? Key State Tax Insights for Marathon Oil Employees

Healthcare Provider Update: Healthcare Provider for Marathon Oil: Marathon Oil utilizes various healthcare providers for its employee health insurance plans, including major national insurers such as UnitedHealthcare, Anthem Blue Cross Blue Shield, and Cigna. These partnerships typically aim to deliver comprehensive health coverage to employees, taking into account various healthcare needs and preferences. Potential Healthcare Cost Increases in 2026: As we approach 2026, employees of Marathon Oil may face significantly higher healthcare costs due to anticipated sharp increases in Affordable Care Act (ACA) premiums. Projections indicate that up to 92% of ACA policyholders could see their monthly premiums rise by over 75%, largely attributed to the expiration of enhanced federal subsidies. Coupled with record rate hikes from insurers-some exceeding 60%-these factors are creating a perfect storm for increased healthcare expenses, impacting financial planning for many employees considering retirement or changes in coverage. Without proactive strategies, employees may find themselves navigating a challenging healthcare landscape. Click here to learn more

Potential tax implications of moving

If you are thinking of moving to a new state when you retire, there are several factors to consider in advance. Beyond determining if the location suits your needs and lifestyle, it's important to find out how much you will owe in state taxes. That's because both your short- and long-term living expenses can be influenced by property and sales taxes. Additionally, certain states have estate and inheritance taxes that may affect your legacy planning.

Even if you plan to move to a state with no income tax after retiring from Marathon Oil, look closely at the full tax landscape before making the leap. In truth, income tax is just one piece of a larger equation. Here are four core tax categories to keep in mind:

1. Income taxes

As of 2025, wage income is not taxed at the state level in nine U.S. states: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. This can make these states attractive to Marathon Oil retirees who anticipate earning a higher income even after retirement.

If you plan to meet most of your income needs from pensions, traditional IRAs, and employer retirement plans, this income is generally subject to federal taxes and may be subject to state taxes. That said, most states do not tax Social Security benefits. Be sure to check if that's true in the state you'd like to move to. There are still nine states that impose income tax on Social Security, although they typically also offer exemptions or credits based on your income level. ¹

Comparing estimated state and federal taxes on retirement withdrawals can help clarify how your income could differ depending on where you live. State rules, exemptions, and formulas can vary widely.

2. Property tax

Property tax costs differ greatly depending on where you live. New Jersey, for instance, has an effective property tax of 2.23%, while Hawaii's property tax is only 0.27%. ²  According to the U.S. Census Bureau, the national average is 1.02%. ³  

In some states, eligible homeowners could see cost reductions through age-based or homestead exemptions. However, this is not universally true. This makes it important to understand the property tax landscape in advance of making any moves. Location and real estate values will heavily influence your total housing-related expenses in retirement.

3. Sales tax

Sales taxes can shape everyday spending, especially for retirees living on fixed income sources of revenue. As of 2025, 45 states impose a statewide sales tax, and 38 states have additional local sales taxes levied by counties or municipalities. ⁴  While exemptions for items like groceries or clothing may exist, they vary widely between states. And these exemptions typically do not mitigate sales taxes on other items, which average 7.52% nationwide. ⁴  Even in places without income taxes, the combined sales tax burden can noticeably impact the cost of living.

4. Inheritance and estate taxes

Other taxes you should consider before moving include those levied on estates and inheritances. These can be crucial as they may influence how much your heirs ultimately receive.

In addition to federal estate tax, 12 states and the District of Columbia impose estate taxes and five states levy inheritance taxes. And then there's Maryland, the only state that charges both. ⁵

Before relocating, be sure to review estate tax laws in both your current and future state of residence since rules and thresholds differ.

The bottom line

Taxes are only one piece of the cost-of-living puzzle. Housing, health care, and insurance may also factor heavily into retirement planning for those leaving the Marathon Oil workforce.

Taking a full view of a state’s tax environment can help you make sound, well-considered choices. Working with a financial planner or tax professional can help you evaluate how a move could influence your income, assets, and long-term goals.
