Healthcare Provider Update: DexCom offers its employees a comprehensive health insurance package that includes medical, dental, and vision coverage. Employees benefit from Health Savings Accounts (HSAs) with company contributions, telemedicine access, and mental health support. Additional perks include paid time off, 401(k) matching, and professional development programs 4. Healthcare costs in the United States are projected to continue rising through 2026, with insurers proposing significant premium increases for Affordable Care Act (ACA) plans. A recent analysis found that ACA insurers are seeking a median premium increase of 15% for 2026, marking the largest hike since 2018. This surge is attributed to factors such as the anticipated expiration of enhanced premium tax credits, rising medical costsincluding expensive medications and increased hospital staysand a shift in the risk pool towards higher-cost enrollees. Without the renewal of enhanced subsidies, out-of-pocket premiums for ACA marketplace enrollees could increase by more than 75% on average. Click here to learn more

How federal tax brackets work and why they matter.
How taxable income is calculated for retirement planning.
Strategies that may help reduce taxable income.

Navigating taxes can feel more manageable when you understand how your income is allocated to various federal tax bands. Income tax is calculated by the IRS using seven brackets that adjust annually for inflation. You do not pay the same rate on every dollar you earn because income is taxed progressively. Instead, your taxable income is divided into ranges, each taxed at its own rate. DexCom employees can benefit from understanding how their tax brackets may change as they prepare for retirement income decisions.

Below are the IRS’s official 2025 and 2026 bracket tables, along with an explanation of how federal brackets work. The Retirement Group can help review how these rules may influence your long-term income strategy. You can reach us at (800) 900-5867 .

How Federal Tax Brackets Work

The seven federal income tax brackets in the United States are 10%, 12%, 22%, 24%, 32%, 35%, and 37% .

This progressive structure means that each additional portion of income is taxed according to the next bracket as taxable income increases, which may be important for DexCom employees reviewing future retirement income.

Your marginal tax rate applies to the last dollar of taxable income you earn. Your effective tax rate represents the overall percentage of income paid toward federal tax after all brackets are applied.

Your tax brackets also depend on the filing status you choose:

- Single
- Married filing jointly
- Married filing separately
- Head of household (single with a qualifying dependent)

The IRS adjusts these brackets every year to account for inflation.

How Your Taxable Income Is Calculated

To determine taxable income, start by adding all sources of taxable income, such as interest, qualifying pre-2019 alimony, tips, bonuses, and both employment and freelance earnings.

Next, subtract items already included on your W-2, such as contributions to a health savings account (HSA) or retirement plan contributions through your employer (401(k)).

Then subtract either your itemized deductions or the standard deduction—whichever applies. The remaining amount is your taxable income.

A Federal Effective Tax Rate Example

If a married couple with $150,000 in total income files jointly in 2025 and takes the standard deduction of $31,500 , their taxable income becomes $118,500 . Their federal tax calculation would look like this:

- 10% on the first $23,850 → $2,385
- 12% on $23,851 to $96,950 → $8,772
- 22% on the remaining amount up to $118,500 → $4,741

- Total federal income tax: $15,898

- Effective tax rate: approximately 10.6%

Possible Strategies to Lower Taxable Income

These approaches may help reduce taxable income and potentially push you into a lower tax bracket:

- Contributing to traditional IRAs or employer retirement plans
- Adding funds to an HSA if enrolled in a qualifying high-deductible health plan
- Using tax-loss harvesting in taxable brokerage accounts
- Considering the timing of controlled income, such as bonuses or freelance payments

Starting in 2026, taxpayers who do not itemize may deduct up to $1,000 (single filers) or $2,000 (married filing jointly) for eligible cash charitable contributions.

DexCom offers a 401(k) plan but does not currently provide a defined pension plan for its employees. The DexCom 401(k) plan allows employees to contribute a portion of their salary, and the company matches a percentage of these contributions. As of 2022, the plan's total retirement assets were over $234 million, with 5,430 participants. The plan is accessible to all full-time employees aged 21 and over, with the option to start contributing immediately upon employment. For specific terminology and detailed plan descriptions, DexCom uses standard retirement-related terms like "vesting," "deferral," and "matching contributions." The plan focuses on providing long-term savings opportunities, emphasizing employee participation and the benefits of employer matching.

Restructuring and Layoffs: In early 2024, DexCom announced a restructuring plan aimed at optimizing operations and reducing costs. The company is expected to lay off approximately 5% of its workforce as part of this initiative. This move is a strategic response to the current economic uncertainties and is designed to enhance efficiency and profitability amidst fluctuating market conditions. The importance of addressing this news is heightened by the current economic environment, which is marked by inflationary pressures and changing investment dynamics. Understanding such developments is crucial for assessing the potential impact on employee benefits and job security. Company Benefits and Pension Changes: Alongside the restructuring, DexCom has also made adjustments to its benefits and pension plans. The company has modified its 401(k) match policy, reducing the employer contribution rate from 5% to 3%. Additionally, there have been changes to the pension plan, including a freeze on new pension accruals. These changes reflect broader trends in the industry where companies are reassessing their benefits structures in response to financial pressures. It is essential to monitor these developments as they affect employee retirement planning and long-term financial stability, especially in light of current tax and investment environments.

DexCom provided stock options to executives and key employees, with a four-year vesting schedule. RSUs were granted to align interests with shareholders, typically vesting over three years.
