How Progressive Taxation Works
A common misconception is that moving into a higher tax bracket means your entire salary is taxed at that new rate. Fortunately, the US uses a **Marginal Tax System**. Think of your income as water filling a series of buckets. Only when the first bucket is full does the water spill over into the next, higher-taxed bucket.
2026 Estimated Federal Tax Brackets (Single Filers)
To understand how your 2026 income tax is calculated, look at the marginal rates below. These represent the "buckets" for the current year:
| Tax Rate | Income Range (Single) | Tax Owed for Bracket |
|---|---|---|
| 10% | $0 – $11,925 | 10% of taxable income |
| 12% | $11,926 – $48,475 | $1,192.50 + 12% of amount over $11,925 |
| 22% | $48,476 – $103,350 | $5,578.50 + 22% of amount over $48,475 |
| 24% | $103,351 – $197,300 | $17,651 + 24% of amount over $103,350 |
The Danger of Bracket Creep
**Tax Bracket Creep** occurs when your nominal income rises (perhaps due to a cost-of-living raise) but the tax brackets stay relatively static. Because you are earning more "dollars"—even if those dollars buy less than they used to—a larger percentage of your income falls into higher-tax buckets.
-
Marginal Rate vs. Effective Rate
Your marginal rate is the tax on your last dollar. Your effective rate is the actual percentage of your total income that goes to the IRS. Most people pay an effective rate significantly lower than their top bracket.
-
The Standard Deduction
Before applying these brackets, you subtract the Standard Deduction (approx. $15,000 for singles in 2026). This income is taxed at 0%.
Three Ways to Fight Bracket Creep
If you are worried that your next raise will be swallowed by taxes, consider these tax-efficient strategies:
- Maximize 401(k) or 403(b) Contributions: These are "pre-tax" contributions that lower your taxable income, potentially keeping you in a lower bracket.
- Health Savings Accounts (HSAs): Contributions are 100% tax-deductible, providing a "triple tax advantage" while lowering your AGI.
- Tax-Loss Harvesting: Offsetting capital gains with losses can reduce your overall taxable income at the end of the year.
