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. Illumina 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 Illumina 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.
