Taxes

Tax Brackets

One of the most persistent and damaging myths in personal finance is the fear of "moving into a higher tax bracket." You will often hear people say, “I don't want that raise or bonus, because it will bump me into a higher tax bracket and I’ll actually end up taking home less money.”

This is mathematically impossible.

"Buckets"

The confusion stems from a misunderstanding of how a progressive tax system works. The United States (and many other countries) uses marginal tax rates. You do not pay a single, flat percentage on your entire income. Instead, you should think of tax brackets like a series of buckets filling up with water.

Here is a simplified example using imaginary numbers:

• Bucket 1: $0 to $10,000 is taxed at 10%

• Bucket 2: $10,001 to $40,000 is taxed at 12%

• Bucket 3: $40,001 to $90,000 is taxed at 22%

If you earn $45,000 a year, you are technically in the "22% tax bracket." However, all of your income is not taxed at 22%.

Instead, your income fills up the buckets one by one:

• Your first $10,000 fills Bucket 1 and is taxed at 10% ($1,000).

• Your next $30,000 fills Bucket 2 and is taxed at 12% ($3,600).

• Only your final $5,000 spills over into Bucket 3 and is taxed at the higher 22% rate ($1,100).

Even though you are in the 22% bracket, your total tax bill is $5,700. If you divide that by your total income ($45,000), you will see that you actually paid about 12.6% of your total income in taxes.

Be sure to check out the latest federal and state tax brackets. These do not include FICA taxes, which is a flat 7.65% on the first $184,500 as of 2026.

Tax Rates

This brings us to two crucial terms you need to know:

• Marginal Tax Rate: The highest bracket you reach (22% in this example). This is the tax you will pay on your next dollar earned.

• Effective Tax Rate: The actual percentage of your total income that you paid in taxes (12.6% in this example). This is the number that truly matters for your budget.

Bottom Line

Because only the money that spills over into the next bucket is taxed at the higher rate, earning more money will always result in more money in your pocket. Never turn down a raise think you will lose money.

Deductions & Credits

Your taxable income is not your salary, it is your salary minus every deduction and adjustment you take. Every reduction to that number saves you money at your marginal rate, the rate applied to your last dollar of income.

Below we will go over how the calculation works and what kinds of deductions and credits most people can take. Click here for an up-to-date list of deductions.

Calculating Your Taxes

1. You start with gross income:

   • • Wages/Salary

     • Interest

     • Dividends

     • Any other income you received during the year

2. From there, you subtract above-the-line deductions (discussed in the next section) to arrive at your Adjusted Gross Income (AGI), which determines your eligibility for a range of credits and deductions.

3. From AGI, you subtract either the standard deduction or your itemized deductions, whichever is larger, to get your taxable income. The vast majority of people take the standard deduction, as it is difficult to itemize enough without a business.

4. You then apply the tax brackets to that number to calculate your gross tax liability.

5. From that liability, you subtract any tax credits you qualify for to arrive at your final bill.

Above-the-Line Deductions

Above-the-line deductions are subtracted from gross income before you arrive at AGI. They are called "above the line" because they appear above the AGI line on your tax return, and they are available whether or not you itemize.

• Investment Accounts: Traditional 401(k), traditional IRA, and HSA contributions are the most readily available above-the-line deductions for salaried employees. As of 2026, the combined contribution limit is $36,400.

• Student Loan Interest Deduction (SLID): Payments toward student loan interest is deductible up to $2,500 per year, subject to income phase-outs.

• Charity Contributions: New for 2026 is being able to take an above-the-line deduction up to $1,000 for a single filer, or $2,000 for married filing jointly.

The Standard Deduction vs. Itemizing

After above-the-line deductions reduce your gross income to AGI, you choose between the standard deduction and itemizing. You take whichever is larger, which is the standard deduction for over 90% of Americans. For 2026, it is $16,100 for single filers and $32,200 for married filing jointly.

For most salaried Americans without a mortgage, significant charitable giving, or business expenses, itemizing is simply not worth the effort. The standard deduction already exceeds what they could claim by listing individual deductions knowing this ahead of time prevents wasted effort.

Itemizing becomes worth considering when the sum of your eligible deductions exceeds the standard deduction threshold. The major itemized deductions available to non-business owners are as follows.

• State and Local Taxes (SALT): Allows you to deduct state income taxes and property taxes, currently capped at $10,000 combined per return.

• Mortgage Interest: Payments toward interest on your primary residence and one secondary residence is deductible on loan balances up to $750,000 for mortgages from after December 2017. This deduction is the primary reason homeowners with larger mortgages benefit from itemizing. Early in a mortgage, when payments are heavily weighted toward interest, the deduction is most valuable. As the mortgage matures and more of each payment goes to principal, the deduction shrinks.

• Charitable Contributions: Cash contributions to qualifying organizations are deductible up to 60% of your AGI, while non-cash contributions have their own rules and limits. Donating appreciated stock directly to a charity rather than selling it first and donating cash is a particularly efficient strategy, as you avoid capital gains tax on the appreciation and still deduct the full fair market value.

• Medical Expenses: Any that exceed 7.5% of your AGI are deductible. In practice, this threshold is high enough that only people with very significant medical costs in a given year clear it.

Common Tax Credits

Tax credits reduce your final bill directly and are therefore worth understanding even if their names sound arcane.

• Child Tax Credit: Provides up to $2,000 per qualifying child under 17, with a portion being refundable, meaning it can reduce your bill below zero and generate a refund even if you owed nothing.

• Child and Dependent Care Credit: Covers a percentage of childcare expenses incurred while you work or look for work. It applies to daycare, after-school programs, and summer camps for children under 13. The credit is non-refundable, meaning it can reduce your bill to zero but not below it.

• Earned Income Tax Credit (EITC): Specifically designed for lower-to-moderate income working individuals and families and is one of the most valuable credits in the code for those who qualify. It is refundable, and the credit amount varies with income, filing status, and number of children.

• Saver's Credit: Provides a credit of 10–50% of retirement contributions (401k, IRA) for lower-income filers. It is designed to incentivize retirement saving among people who most need the encouragement. If your income is below the qualifying threshold, this credit stacks directly on top of the tax deduction from the contribution itself.

• American Opportunity Tax Credit and Lifetime Learning Credit: Covers qualified education expenses. The AOTC is worth up to $2,500 per year for the first four years of higher education and is partially refundable. The LLC covers a broader range of educational expenses beyond the first four years and is worth up to $2,000 per return.

Roth vs. Traditional

Both Traditional and Roth accounts shelter your investments from taxes on dividends, interest, and capital gains; the difference is when you pay tax on the money.

With a Traditional account, you contribute pre-tax dollars, reducing your taxable income now. The money grows tax-deferred, and you pay ordinary income tax on withdrawals in retirement. With a Roth account, you contribute after-tax dollars, so they are taxed today. The money grows tax-free, and qualified withdrawals in retirement are entirely tax-free. Assuming the same marginal tax rate now and later, the result is the same. Let's look at an example if you had $10,000 to invest and let it grow for 10 years with a marginal tax rate of 22%:

• Traditional

  • $10,000 Invested

  • After 10 Years: $25,937.42

  • Amount After Tax on Withdrawal: $22,824.93

• Roth

  • $10,000 Available, $8,800 Invested After Taxes

  • After 10 Years: $22,824.93

The general rule of thumb is to make traditional contributions when you expect to be in a lower tax bracket in retirement and Roth contributions when you expect to be in a higher bracket. For most people early in their careers, Roth contributions are advantageous because current income is lower than they are likely to be at peak earning years, while for people in peak earning years in high tax brackets, Traditional contributions provide valuable deductions that are likely to be at higher rates than in retirement. However, we do not know what tax rates will be like in retirement, and the amount you will have 30 years down the line is unpredictable. A simple method for most is to use a Traditional 401(k) and Roth IRA, allowing you to mix tax benefits and giving you flexibility in retirement. Below are a few additional considerations:

• For lower income individuals, getting tax breaks now may be integral to affording key expenses

• Traditional accounts have required monthly distributions starting at age 73

• The tax deduction for Traditional IRAs phases out based your income

• Roth IRAs have an income limit for direct contributions, but you can easily do a backdoor Roth, which is basically contributing to a Traditional IRA and converting it to a Roth IRA

Common Mistakes

Misunderstanding Tax Brackets

The United States uses a marginal tax system, meaning only the income within each bracket is taxed at that bracket's rate. If you are a single filer with $50,000 of taxable income in 2025, you do not pay 22% on all of it. This is explained it more detail above. Understanding this prevents the irrational fear of "moving into a higher bracket" causing you to avoid a raise or additional income.

Waiting Until Tax Season

Do not wait until April to think about taxes. The highest-leverage decisions, like retirement account contributions, happen during the year, not after it ends. By the time you are preparing them, almost all of the meaningful decisions for that tax year are already made. Setting yourself up now helps you save on taxes in the future.

Overpaying for Tax Software or Professionals

If you are a salaried employee with a W-2, no business income, standard investment accounts, and no unusual life events, you shouldn't need help preparing your taxes. The value of a CPA or tax professional is real, but mostly just for complex situations: self-employment, significant investment activity, and major life changes. For the straightforward majority, the money spent on an expensive preparer is a cost, not an investment. File at FreeTaxUSA to get your federal return for free and pay just ~$15 for your state return.
