How tax brackets work, and why a raise still pays
This is informational and not tax advice.
The belief that a raise can leave you worse off is one of the most persistent misunderstandings in personal finance, and it occasionally causes real harm when people decline additional work or hours to avoid crossing a line. The fear rests on a misreading of how brackets operate. Working through an actual salary against the current rates settles it in about two minutes.
Marginal and effective rates
A tax bracket does not apply to your whole income. It applies to the portion of income that falls inside it.
Your marginal rate is the rate charged on your next dollar of income. Your effective rate is the total tax divided by total income, and it is always lower than the marginal rate for anyone above the first bracket, because the earlier portions were taxed at lower rates.
When someone says they are “in the 22% bracket”, they mean their marginal rate is 22%. They are not paying 22% on everything, and the gap between the two figures is usually large.
The 2026 brackets
For tax year 2026, the seven rates apply to a single filer as follows.
| Rate | Taxable income, single filer |
|---|---|
| 10% | $0 to $12,400 |
| 12% | $12,400 to $50,400 |
| 22% | $50,400 to $105,700 |
| 24% | $105,700 to $201,775 |
| 32% | $201,775 to $256,225 |
| 35% | $256,225 to $640,600 |
| 37% | Above $640,600 |
For married couples filing jointly the thresholds are broader: 10% to $24,800, 12% to $100,800, 22% to $211,400, 24% to $403,550, 32% to $512,450, 35% to $768,700, and 37% above that.
Note the column heading. These apply to taxable income, which is what remains after deductions, not to your salary. For 2026 the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.
Walking one salary through the brackets
A single filer earning $66,000, taking the standard deduction.
Taxable income: $66,000 minus $16,100 equals $49,900.
| Portion | Rate | Tax |
|---|---|---|
| First $12,400 | 10% | $1,240 |
| Next $37,500 (from $12,400 to $49,900) | 12% | $4,500 |
| Total | $5,740 |
Marginal rate: 12%. Effective rate against gross salary: 8.7%.
Why a raise never lowers take-home
Now the same person receives a $5,000 raise, taking them to $71,000. Taxable income becomes $54,900, which crosses into the 22% bracket.
| Portion | Rate | Tax |
|---|---|---|
| First $12,400 | 10% | $1,240 |
| $12,400 to $50,400 | 12% | $4,560 |
| $50,400 to $54,900 | 22% | $990 |
| Total | $6,790 |
Compare the two outcomes directly.
| Before | After | |
|---|---|---|
| Gross salary | $66,000 | $71,000 |
| Federal income tax | $5,740 | $6,790 |
| Left after this tax | $60,260 | $64,210 |
The raise was $5,000. Additional tax was $1,050. Take-home rose by $3,950.
Here is the specific point the myth gets wrong. Only $4,500 of the raise was taxed at 22%, producing $990. The other $500 was still taxed at 12%, producing $60. Nothing that was already being taxed at 12% moved up to 22%. The higher rate reached only the income above the threshold, which is what “marginal” means.
Note also that the marginal rate is now 22% while the effective rate is 9.6%. Someone describing themselves as “in the 22% bracket” is paying well under ten per cent of their salary in federal income tax.
Where the myth comes from
It is not invented out of nothing. Three real things produce the sensation it describes.
Benefit cliffs. Some assistance programmes and credits phase out or terminate at defined income levels, and those genuinely can be sharp. A cliff of this kind is a feature of the benefit, not of the tax brackets, but the experience is real and the two get conflated.
Withholding changes. A bonus or a raise can be withheld at a different rate than your regular pay, making a single paycheque look worse than expected. Withholding is an estimate settled at filing, not the tax itself.
Other thresholds. Additional taxes, contribution limits and phase-outs attach at various income levels, and crossing several at once can make the marginal effect on a particular increase feel large.
None of these mean that the income tax brackets themselves reduce take-home pay when income rises. Within the bracket structure alone, more gross income always produces more net income.
Deductions and the standard deduction
Because the rates apply to taxable income, deductions move the whole calculation down the table.
Most filers take the standard deduction, which requires no records and no itemising. Itemising is worthwhile only when your qualifying deductions exceed the standard amount, which for 2026 means clearing $16,100 as a single filer or $32,200 filing jointly.
Contributions to certain retirement and health accounts can reduce taxable income further, which lowers tax at your marginal rate rather than your effective one. That distinction is the reason such contributions are worth most to people in higher brackets, and it is the practical use of understanding the difference between the two rates.
