Tax Brackets Explained: Why That Big Raise Might Sting

TL;DR:
Before you pop champagne over that raise, hit pause. If you don’t understand how tax brackets work, you might end up with less in your pocket than expected. Here’s the scoop on tax brackets explained, plus smart taxable income tips to help you save money on taxes before Uncle Sam swoops in.

You finally got the raise you worked your hoodie off for—nice. But why does your paycheck look… not so upgraded? Here’s the real plot twist: the U.S. tax system is marginal, which means only the extra income over each bracket limit gets taxed at the higher rate. So no, getting a raise won’t launch your whole paycheck into a higher tax tier. But without some strategy, you can lose more than you should.

Welcome to the world of marginal tax brackets—where getting paid more doesn’t always mean keeping more. Gen Z and Millennials, especially those navigating promotions, side hustles, or new salary tiers, should absolutely understand how tax brackets work and how to legally reduce taxable income with pre-tax contributions.

Tax Brackets Explained: It’s Not All or Nothing

A lot of folks think a raise means their entire income gets taxed at the new rate. That’s a tax myth, like thinking avocado toast ruined our homeownership dreams.

The Truth About Marginal Tax Brackets

Here’s how it actually works:

• The IRS splits your income into portions (a.k.a. tax brackets).

• Each portion is taxed at a different rate.

• Only the amount within each bracket gets taxed at that rate—not your entire income.

Example:
Let’s say you earn $50,000 and then get a raise to $60,000. If the 22% bracket starts at $47,151, only the $12,849 above that gets taxed at 22%. The first chunks of your income are still taxed at the lower 10% and 12% rates.

2025 Federal Tax Brackets (For Single Filers):

1. 10% on income up to $11,600

2. 12% on $11,601 to $47,150

3. 22% on $47,151 to $100,525

4. (It climbs from there, but you get the idea)

Smart Ways to Legally Lower Your Taxable Income

Getting a raise is great. Keeping more of it is even better. Here’s how you can reduce your taxable income using perfectly legal, pre-tax strategies.

1. Beef Up Your 401(k)

• Contributions are pre-tax.

• Lowers your taxable income today while investing in your future.

2. Contribute to an HSA or FSA

• Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) also reduce your taxable income.

• Triple tax advantage: contribute pre-tax, grow tax-free, withdraw tax-free for qualified expenses.

3. Deduct Student Loan Interest

• If you’re paying down debt, you may qualify for a deduction up to $2,500 in interest.

4. Use Pre-Tax Commuter Benefits

• Public transportation or parking expenses? You might be able to pay pre-tax.

5. Donate Smart

• Charitable donations can reduce taxable income—but only if you itemize.

Pro Tip:

Always review these options during open enrollment or when you’re setting up direct deposit. A 10-minute tweak could mean hundreds saved on taxes.

But Wait—What About Side Hustles?

Good question. If you’re freelancing, Ubering, or selling your Beanie Babies on Etsy, congrats—you’re self-employed. And that means you get access to even more ways to reduce your taxable income.

Write-Off Heaven

• Internet bill (if you work from home)? Deductible.

• New laptop for editing TikToks? Deductible.

• Your portion of rent for the home office? Yep—also deductible.

Just keep clean records and receipts. The IRS doesn’t play when it comes to documentation.

Tax brackets are layered like a birthday cake, not a trap. You can (and should) celebrate that raise. Just be smart about it.

Here’s the recap:

• Only the extra income gets taxed higher.

• The more you know, the more you keep.
