What’s a tax bracket?

A tax bracket is a range of income that gets taxed at a specific rate. The United States uses a progressive tax system, meaning your income is divided into layers, and each layer is taxed at successively higher rates as your income increases.

Some people mistakenly believe that getting a raise bumps them into a higher tax bracket, and that the extra income isn’t worth it. In reality, getting bumped into a higher tax bracket doesn’t mean all of your income gets taxed at the higher rate — only the portion of income that falls within that bracket does. So if you get a raise, take the money, then use smart tax strategies to keep more of it.

Think about it this way:

• The first $11,925 of your income is taxed at 10%.
• The next $11,926 – $48,475 is taxed at 12%.
• And so on, up the brackets.

2025 and 2026 federal tax brackets

For income earned in 2025 (returns filed in 2026) and 2026, the IRS set the brackets below. They reflect the inflation-adjusted thresholds published in IRS Revenue Procedures, which apply the Chained Consumer Price Index (C-CPI) to account for inflation.

One important note: tax brackets apply to your taxable income, not your overall gross income. To find your taxable income, subtract your standard deduction (and any other deductions) from your gross income.

For 2025, the standard deductions are $15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household. For 2026 they rise to $16,100, $32,200, and $24,150, respectively.

If you earn $65,000 as a single filer in 2025, your taxable income after the standard deduction is $50,000 — which puts you firmly in the 22% bracket, not the 24% bracket. That single deduction alone saves you several thousand dollars.

And if you’re self-employed, you’re eligible for a ton of deductions (the QBI deduction, the home office deduction, and other deductible business expenses) that lower your taxable income even further — and those apply on top of the standard deduction.

Marginal tax rate vs. effective tax rate

There are two numbers most people confuse, and conflating them is one of the most common tax mistakes out there.

Your marginal tax rate is the rate applied to your last dollar of income — the highest bracket you fall into. If you’re a single filer with $90,000 in taxable income in 2025, your marginal rate is 22%. But that rate only applies to a small slice of your income: the first $11,925 was taxed at 10%, the next chunk at 12%, and only income above $48,475 hits the 22% rate. So your marginal rate tends to inflate what you think you owe.

Your effective tax rate is the actual overall percentage of your income you pay in federal income tax, found by dividing your total tax by your total income. It’s almost always lower than your marginal rate, and it’s the number that tells you what you’re really paying.

Here’s a worked example — a single filer with $90,000 of taxable income in 2025. Only the income within each bracket is taxed at that bracket’s rate:

The marginal rate is 22%, but the effective rate — what you actually pay — is just 16.4%. This gap is why deductions are so powerful for higher earners. Every dollar you deduct reduces your taxable income. In the 22% bracket, a $5,000 deduction saves you $1,100 in taxes; in the 32% bracket, that same $5,000 saves you $1,600.

How to lower your tax bracket

Most tax advice stops at “claim your deductions.” But a good CPA thinks ahead about timing, investment structure, and the interplay between federal and state taxes. Every situation is unique, and it’s important to understand the full context of yours to make the right moves.

Max your pre-tax retirement contributions

Every dollar contributed to a traditional 401(k) or IRA reduces your taxable income dollar-for-dollar. The 2025 401(k) limit is $23,500 (plus a $7,500 catch-up for those 50+). For someone in the 22% bracket, maxing the 401(k) alone can cut their tax bill by over $5,000 and shift a portion of their income into the 12% bracket.

Fund an HSA

If you have a high-deductible health plan (HDHP), a health savings account is a triple tax advantage: contributions are deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. The 2025 contribution limit is $4,300 for self-only coverage and $8,550 for family coverage — one of the most underused deductions for middle-income earners.

Consider a Roth conversion in low-income years

If your income temporarily drops due to a job change, sabbatical, or early retirement, it can be a smart time to convert a traditional IRA to a Roth. You’ll pay taxes on the conversion now, but at a lower rate, and future Roth withdrawals are tax-free. This requires precise planning, but the long-term savings can be substantial.

Time bonuses and self-employment income strategically

If you expect a large bonus or self-employment income and you’re near a bracket threshold in December, ask whether it can be deferred to January. Conversely, if your income this year is unusually low, you might accelerate income into this year to take advantage of a lower rate. This kind of income timing is exactly the conversation CPAs have with clients in Q4.
