2026 Federal Income Tax Brackets: Rates, Thresholds, and Worked Math
For tax year 2026, the return you file in 2027, the United States keeps seven federal income tax rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For a single filer the 10% rate covers the first $12,400 of taxable income and the 37% rate starts above $640,600. The standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household. A single worker earning $75,000 in wages owes $7,670 of federal income tax before credits, an effective rate of 10.23%, even though the top dollar is taxed at 22%.

Educational only, not tax advice. Every person in this guide is a labeled hypothetical with stated inputs. Rates, thresholds, and deduction amounts come from IRS Revenue Procedure 2025-32 and the IRS pages named where each figure is used, checked October 2026.
1. The seven 2026 brackets for each filing status
The thresholds below are taxable income, which is income after the standard deduction (or itemized deductions) and any other deductions have been subtracted. They are taken from the tax rate tables in section 4.01 of IRS Revenue Procedure 2025-32 (checked October 2026), which the IRS announced in its news release on tax year 2026 inflation adjustments (checked October 2026).
Single filers (unmarried, not head of household)
| Rate | Taxable income over | But not over | Tax at the bottom of the band |
|---|---|---|---|
| 10% | $0 | $12,400 | $0 |
| 12% | $12,400 | $50,400 | $1,240 |
| 22% | $50,400 | $105,700 | $5,800 |
| 24% | $105,700 | $201,775 | $17,966 |
| 32% | $201,775 | $256,225 | $41,024 |
| 35% | $256,225 | $640,600 | $58,448 |
| 37% | $640,600 | no limit | $192,979.25 |
Married filing jointly (and surviving spouses)
| Rate | Taxable income over | But not over | Tax at the bottom of the band |
|---|---|---|---|
| 10% | $0 | $24,800 | $0 |
| 12% | $24,800 | $100,800 | $2,480 |
| 22% | $100,800 | $211,400 | $11,600 |
| 24% | $211,400 | $403,550 | $35,932 |
| 32% | $403,550 | $512,450 | $82,048 |
| 35% | $512,450 | $768,700 | $116,896 |
| 37% | $768,700 | no limit | $206,583.50 |
Head of household
| Rate | Taxable income over | But not over | Tax at the bottom of the band |
|---|---|---|---|
| 10% | $0 | $17,700 | $0 |
| 12% | $17,700 | $67,450 | $1,770 |
| 22% | $67,450 | $105,700 | $7,740 |
| 24% | $105,700 | $201,750 | $16,155 |
| 32% | $201,750 | $256,200 | $39,207 |
| 35% | $256,200 | $640,600 | $56,631 |
| 37% | $640,600 | no limit | $191,171 |
Married couples filing separately use the single thresholds up to the 35% band, which for them ends at $384,350. Above that, the 37% rate applies, starting from a base of $103,291.75.
The last column is the cumulative tax on every band below. It is how the IRS itself states the schedule: a single filer with $58,900 of taxable income owes $5,800 plus 22% of the $8,500 above $50,400. Every base amount in these tables was re-derived band by band for this guide and matches the Revenue Procedure to the cent.
Three patterns worth noticing
Joint thresholds are double the single thresholds, until they are not. From the 10% band through the 32% band, every joint threshold is exactly twice the single one ($24,800 versus $12,400, $403,550 versus $201,775). The 35% band for joint filers starts at $512,450, also double. But the 37% rate for couples starts at $768,700, while twice the single threshold would be $1,281,200. Section 9 prices what that gap costs a two-earner couple at the top.
Head of household is a wider version of single, not a smaller version of joint. The 10% and 12% bands are wider for heads of household ($17,700 and $67,450 against $12,400 and $50,400), the 22% band ends at the same $105,700, and the upper thresholds sit within $25 of the single ones ($201,750 against $201,775, $256,200 against $256,225). The top rate starts at the same $640,600. So the head of household advantage is concentrated in the lower and middle bands, plus a larger standard deduction.
The rate list itself did not change. The 2026 tables use the same seven rates that applied in 2025. What changed is the dollar thresholds, which move each year for inflation, and the legal status of the rates, covered in section 6.
2. The 2026 standard deduction and the other amounts that set taxable income
Brackets apply to taxable income, so the first number that matters is the deduction that stands between your gross income and the brackets. For 2026, section 4.14 of Rev. Proc. 2025-32 sets these amounts:
| Item (tax year 2026) | Amount | Who it applies to |
|---|---|---|
| Standard deduction, single | $16,100 | Unmarried filers who are not heads of household |
| Standard deduction, married filing separately | $16,100 | Each spouse filing a separate return |
| Standard deduction, married filing jointly | $32,200 | Couples on one return, and surviving spouses |
| Standard deduction, head of household | $24,150 | Unmarried filers who qualify as head of household |
| Additional standard deduction, aged or blind | $1,650 | Per qualifying condition, for married filers and surviving spouses |
| Additional standard deduction, aged or blind, unmarried | $2,050 | Per qualifying condition, unmarried and not a surviving spouse |
| Dependent's standard deduction | Cannot exceed the greater of $1,350, or $450 plus earned income | Someone who can be claimed as a dependent by another taxpayer |
| Personal exemption | $0 | Everyone |
For comparison, the 2025 amounts were $15,750 for single and separate filers, $31,500 for joint filers, and $23,625 for heads of household, per the IRS news release. The single amount rose by $350, the joint amount by $700, and the head of household amount by $525.
The aged-or-blind addition stacks. A married couple filing jointly in which both spouses are 65 or older adds $1,650 twice, for a standard deduction of $35,500 before any senior deduction from Schedule 1-A. A single filer who is both 65 or older and blind adds $2,050 twice.
Where each bracket starts in wages
A useful way to read the tables is to add the standard deduction back and ask where each rate begins in gross wages for someone with no other deductions. This table is built from the two IRS tables above, and it is the version most people actually need when they look at a paycheck or an offer letter.
| Rate begins at gross wages of | Single | Married filing jointly | Head of household |
|---|---|---|---|
| 10% | $16,100 | $32,200 | $24,150 |
| 12% | $28,500 | $57,000 | $41,850 |
| 22% | $66,500 | $133,000 | $91,600 |
| 24% | $121,800 | $243,600 | $129,850 |
| 32% | $217,875 | $435,750 | $225,900 |
| 35% | $272,325 | $544,650 | $280,350 |
| 37% | $656,700 | $800,900 | $664,750 |
Read it this way: a single worker whose only income is wages and who takes the standard deduction pays no federal income tax on the first $16,100, pays 10% on wages from $16,100 to $28,500, and reaches the 22% rate only on wages above $66,500. Pre-tax 401(k) deferrals, health savings account contributions, and other above-the-line amounts push every one of these starting points higher still, which is why a 401(k) contribution near a threshold is often discussed in bracket terms. The 401(k) calculator shows the long-run side of that trade.
3. Marginal rate versus effective rate
Two rates describe the same return, and mixing them up causes most bracket confusion.
The marginal rate is the rate on the next dollar of taxable income. It is the rate of the highest band your taxable income reaches. It is the right number for questions about change: what happens to tax if income rises by $1,000, or what a $5,000 deduction saves.
The effective rate is total tax divided by income. It answers a different question: what share of income went to federal income tax this year. Because the lower bands are always taxed at their own lower rates, the effective rate is always below the marginal rate once income passes the first band.
There is a further choice inside "effective rate": the denominator. This guide divides federal income tax by gross wages, because gross pay is the figure people know. Dividing by taxable income gives a higher number. For the single $75,000 worker below, $7,670 is 10.23% of gross wages but 13.02% of the $58,900 of taxable income. Both are correct; they answer different questions, and any comparison has to use the same one on both sides.
4. Worked examples at four incomes
Each example assumes wages are the only income, the standard deduction is taken, and no credits, Schedule 1-A deductions, or pre-tax payroll deductions apply. Those assumptions isolate the bracket math. Real returns often differ, and section 9 lists where.
Example A: single filer, $75,000 in wages
Taxable income: $75,000 minus the $16,100 standard deduction is $58,900.
| Band | Income taxed in this band | Rate | Tax |
|---|---|---|---|
| $0 to $12,400 | $12,400 | 10% | $1,240.00 |
| $12,400 to $50,400 | $38,000 | 12% | $4,560.00 |
| $50,400 to $58,900 | $8,500 | 22% | $1,870.00 |
| Total | $58,900 | $7,670.00 |
Check with the IRS schedule: $5,800 plus 22% of $8,500 is $5,800 plus $1,870, which is $7,670.
- Marginal rate: 22%.
- Effective rate on gross wages: $7,670 divided by $75,000 is 10.23%.
- Only $8,500 of the $75,000, about 11% of the paycheck, is taxed at 22%.
Payroll tax on the same wages (rates in section 7): Social Security is 6.2% of $75,000, or $4,650. Medicare is 1.45%, or $1,087.50. Together that is $5,737.50. Federal income tax plus payroll tax is $13,407.50, 17.88% of gross, leaving $61,592.50 before state tax, benefits, and retirement contributions.
Example B: married filing jointly, $150,000 in combined wages
Taxable income: $150,000 minus $32,200 is $117,800.
| Band | Income taxed in this band | Rate | Tax |
|---|---|---|---|
| $0 to $24,800 | $24,800 | 10% | $2,480.00 |
| $24,800 to $100,800 | $76,000 | 12% | $9,120.00 |
| $100,800 to $117,800 | $17,000 | 22% | $3,740.00 |
| Total | $117,800 | $15,340.00 |
- Marginal rate: 22%.
- Effective rate on gross wages: 10.23%.
That result is exactly double Example A, and it is not a coincidence. Because the joint thresholds and the joint standard deduction are each twice the single figures in this range, two $75,000 earners pay $7,670 each as singles or $15,340 together as a married couple. Through the 35% band there is no marriage penalty and no marriage bonus for two equal earners. Unequal earners are different: if one spouse earns all $150,000, filing jointly produces the same $15,340, whereas that person filing as single would have had $133,900 of taxable income and a $24,734 bill. That spread is the familiar marriage bonus for one-earner couples.
Payroll tax: if the $150,000 is two salaries of $75,000, each spouse pays $5,737.50 in Social Security and Medicare, $11,475 together. Social Security and the 1.45% Medicare tax are figured per worker, so the Social Security cap applies to each spouse's wages separately. The 0.9% Additional Medicare Tax is different: employers withhold it per job, but the couple owes it on combined wages above the joint threshold, as section 7 shows.
Example C: head of household, $60,000 in wages
Taxable income: $60,000 minus $24,150 is $35,850.
| Band | Income taxed in this band | Rate | Tax |
|---|---|---|---|
| $0 to $17,700 | $17,700 | 10% | $1,770.00 |
| $17,700 to $35,850 | $18,150 | 12% | $2,178.00 |
| Total | $35,850 | $3,948.00 |
- Marginal rate: 12%.
- Effective rate on gross wages: 6.58%, before credits.
A head of household by definition maintains a home for a qualifying person, and that usually means credits this guide does not model. For many filers at this income the final bill is lower than $3,948 once credits apply. Treat the figure as the pre-credit tax that credits are then subtracted from, not as the amount owed.
For contrast, the same $60,000 on a single return is $43,900 of taxable income and $5,020 of tax, so head of household status is worth $1,072 here before credits. Most of that comes from the $8,050 larger standard deduction and the wider 10% and 12% bands.
Example D: single filer, $250,000 in wages
Taxable income: $250,000 minus $16,100 is $233,900.
| Band | Income taxed in this band | Rate | Tax |
|---|---|---|---|
| $0 to $12,400 | $12,400 | 10% | $1,240.00 |
| $12,400 to $50,400 | $38,000 | 12% | $4,560.00 |
| $50,400 to $105,700 | $55,300 | 22% | $12,166.00 |
| $105,700 to $201,775 | $96,075 | 24% | $23,058.00 |
| $201,775 to $233,900 | $32,125 | 32% | $10,280.00 |
| Total | $233,900 | $51,304.00 |
Check: $41,024 plus 32% of $32,125 ($10,280) is $51,304.
- Marginal rate: 32%.
- Effective rate on gross wages: 20.52%.
Payroll tax here shows all three moving parts. Social Security stops at the 2026 wage base of $184,500, so it is 6.2% of $184,500, or $11,439, not 6.2% of $250,000. Medicare at 1.45% applies to all $250,000, which is $3,625. The 0.9% Additional Medicare Tax applies to wages above $200,000 for a single filer, so 0.9% of $50,000 adds $450. Payroll tax totals $15,514, and federal income tax plus payroll tax is $66,818, which is 26.73% of gross.
5. Original table: 2026 federal income tax and effective rate by income and filing status
This table applies the 2026 brackets and standard deductions to wage income at eight levels. Every cell was computed band by band for this guide from the Rev. Proc. 2025-32 tables. Effective rate is federal income tax divided by gross wages.
Inputs and limits: wages only; standard deduction only (no aged or blind additions); no credits of any kind; no Schedule 1-A deductions; no pre-tax 401(k) or HSA deferrals; no capital gains, dividends, or self-employment income; Alternative Minimum Tax not modeled; payroll tax excluded. Head of household rows in particular overstate what most such filers owe, because the qualifying person usually brings credits.
| Gross wages | Single: tax | Single: effective / marginal | Joint: tax | Joint: effective / marginal | Head of household: tax | HoH: effective / marginal |
|---|---|---|---|---|---|---|
| $30,000 | $1,420 | 4.73% / 12% | $0 | 0.00% / none | $585 | 1.95% / 10% |
| $50,000 | $3,820 | 7.64% / 12% | $1,780 | 3.56% / 10% | $2,748 | 5.50% / 12% |
| $75,000 | $7,670 | 10.23% / 22% | $4,640 | 6.19% / 12% | $5,748 | 7.66% / 12% |
| $100,000 | $13,170 | 13.17% / 22% | $7,640 | 7.64% / 12% | $9,588 | 9.59% / 22% |
| $150,000 | $24,734 | 16.49% / 24% | $15,340 | 10.23% / 22% | $20,991 | 13.99% / 24% |
| $250,000 | $51,304 | 20.52% / 32% | $37,468 | 14.99% / 24% | $46,919 | 18.77% / 32% |
| $500,000 | $138,134.25 | 27.63% / 35% | $102,608 | 20.52% / 32% | $133,508.50 | 26.70% / 35% |
| $1,000,000 | $320,000.25 | 32.00% / 37% | $280,250.50 | 28.03% / 37% | $315,213.50 | 31.52% / 37% |
What the table shows
The effective rate never reaches the marginal rate. Even at $1,000,000 of single wages, where the marginal rate is 37%, the effective rate is 32.00%. Every filer pays 10% on the first band no matter how high income goes.
The gap between marginal and effective is widest just after a threshold. A single filer at $75,000 has a 22% marginal rate but a 10.23% effective rate, a gap of almost 12 points, because only $8,500 of taxable income sits in the 22% band.
Joint rows mirror single rows at double the income, through the 35% band. The joint figure at $150,000 equals twice the single figure at $75,000 ($15,340), and the joint figure at $500,000 equals twice the single figure at $250,000 ($102,608). The pattern breaks only at the top: the joint figure at $1,000,000 is $280,250.50, while twice the single figure at $500,000 is $276,268.50, a difference of $3,982.
A $0 bill can still come with payroll tax. The joint couple at $30,000 owes no federal income tax because wages are below the $32,200 standard deduction, but Social Security and Medicare still take 7.65% of wages, $2,295.
To check any row, subtract the standard deduction for the status, find the band, and apply the "tax at the bottom of the band plus rate times the excess" rule from section 1. The single row at $100,000, for example, is $83,900 of taxable income: $5,800 plus 22% of $33,500 ($7,370), which is $13,170.
6. What the 2025 budget law changed for 2026
The law the IRS calls the One, Big, Beautiful Bill Act (Public Law 119-21, enacted July 4, 2025, and also described on IRS pages as the Working Families Tax Cuts) is the reason the 2026 tables look the way they do. Section 2 of Rev. Proc. 2025-32 lists the changes it made to inflation-adjusted items. The ones that touch an ordinary wage earner's federal bracket math are below.
The rates are now permanent
Before this law, the seven-rate structure that took effect in 2018 was scheduled to end after 2025. Rev. Proc. 2025-32 states that the law amended section 1(j) of the Internal Revenue Code to make those rate tables permanent, and that the seven rates of 10%, 12%, 22%, 24%, 32%, 35%, and 37% remain in effect for individuals. The 2026 thresholds are those tables adjusted for inflation.
The standard deduction was made permanent and raised
The law also made the larger standard deduction permanent and increased its base. For 2025 it set the amounts at $15,750 single, $31,500 joint, and $23,625 head of household, and those amounts are indexed for later years, which is how 2026 arrives at $16,100, $32,200, and $24,150.
The personal exemption stays at zero
The IRS news release states that the personal exemption remains $0 for 2026 and that the law made its elimination permanent. Taxable income therefore never gets a per-person subtraction beyond the standard deduction and the specific deductions below.
Four new deductions on Schedule 1-A, for 2025 through 2028
The IRS describes four deductions that are effective for 2025 through 2028 and that can be claimed whether or not you itemize, on the IRS page on new deductions for working Americans and seniors (checked October 2026). They are claimed on Schedule 1-A. The phase-out arithmetic below comes from the 2025 Schedule 1-A form (checked October 2026); check the 2026 version of the form when you file in 2027.
| Deduction | Maximum | Phase-out starts (modified AGI) | Reduction on the 2025 form |
|---|---|---|---|
| Enhanced deduction for seniors | $6,000 per person age 65 or older ($12,000 if both spouses qualify) | $75,000; $150,000 joint | 6% of modified AGI over the threshold |
| Qualified tips | $25,000 per return | $150,000; $300,000 joint | $100 for each full $1,000 over the threshold |
| Qualified overtime compensation | $12,500; $25,000 joint | $150,000; $300,000 joint | $100 for each full $1,000 over the threshold |
| Qualified passenger vehicle loan interest | $10,000 of interest | $100,000; $200,000 joint | $200 for each $1,000 or part of $1,000 over the threshold |
Conditions from the IRS pages and the form: for the tips, overtime, and senior deductions, a valid Social Security number is required for the person who earned the tips or overtime or who qualifies as a senior, and married taxpayers must file jointly to claim them. For the vehicle deduction, the loan must be for a new personal-use vehicle with final assembly in the US, originated after December 31, 2024, with the VIN reported on the return.
These deductions do not change your adjusted gross income. Schedule 1-A starts from modified AGI (Form 1040 line 11b plus a few excluded amounts) and sends its total to Form 1040 line 13b, below AGI. So they reduce taxable income, and therefore bracket tax, but any other figure keyed to AGI is left as it was.
The senior deduction, worked
IRS Publication 6142 (checked October 2026) says the taxpayer must be 65 or older by the last day of the tax year, and that the deduction is in addition to the existing standard deduction for seniors.
Hypothetical: a single filer, age 67, with $60,000 of income, all taxable, and modified AGI of $60,000. That is under the $75,000 threshold, so the full $6,000 applies.
- Standard deduction $16,100, plus the unmarried aged addition of $2,050, plus the $6,000 senior deduction, totals $24,150.
- Taxable income: $60,000 minus $24,150 is $35,850.
- Tax: $1,240 plus 12% of $23,450 ($2,814) is $4,054.
- Without the senior deduction, taxable income would be $41,850 and tax $4,774. The deduction saves $720, which is $6,000 at the filer's 12% marginal rate.
Same filer at $90,000 of modified AGI: the excess over $75,000 is $15,000; 6% of that is $900; the deduction falls to $5,100. A single filer's deduction reaches zero at $175,000 of modified AGI. For a joint return, the reduction is applied to each qualifying spouse's $6,000, so both amounts reach zero at $250,000.
The overtime deduction, worked
The deduction covers only the premium part of overtime required by the Fair Labor Standards Act: the "half" in time-and-a-half, not the whole overtime paycheck. That definition is the most common source of overstated estimates.
Hypothetical: a worker paid $30 an hour works 200 overtime hours at $45. Overtime pay is $9,000, but the qualified amount is the $15 premium times 200 hours, $3,000. If that worker's modified AGI is under $150,000, the deduction is $3,000. At a 22% marginal rate it is worth $660, not the $1,980 a reader would get by deducting all $9,000.
Hypothetical with a phase-out: a single filer with modified AGI of $160,000 and $8,000 of qualified overtime premium. The excess is $10,000, which is 10 full thousands; 10 times $100 is $1,000; the deduction is $7,000. With taxable income in the 24% band both before and after, it saves $1,680. A single filer's full $12,500 is gone at $275,000 of modified AGI; a couple's $25,000 is gone at $550,000.
The tips deduction, an edge case
The tips cap is $25,000 per return for every filing status, including married filing jointly, unlike the overtime cap, which doubles. The phase-out threshold does double ($300,000 joint), so a couple's full $25,000 deduction is gone at $550,000, and a single filer's at $400,000. The tips must be received in an occupation the IRS lists as customarily receiving tips.
7. Payroll tax in 2026: Social Security and Medicare
Federal income tax is only one of the federal deductions on a paycheck. Social Security and Medicare are figured on wages, not taxable income, and the standard deduction never touches them. IRS Publication 15 (2026) (checked October 2026) sets the Social Security and Medicare figures, and IRS Topic 560 sets the additional 0.9%:
| Payroll item, 2026 | Employee rate | Applies to | Maximum employee tax |
|---|---|---|---|
| Social Security | 6.2% | Wages up to the $184,500 wage base | $11,439 |
| Medicare | 1.45% | All wages, no cap | None |
| Additional Medicare Tax | 0.9% | Wages above $250,000 joint, $125,000 married filing separately, $200,000 for all other filers | None |
The employer pays a matching 6.2% and 1.45%, per Publication 15. There is no employer match on the 0.9% Additional Medicare Tax, per IRS Topic 560 (checked October 2026).
The Additional Medicare Tax withholding mismatch
Topic 560 says an employer must begin withholding the 0.9% once it pays an employee more than $200,000 in a calendar year, regardless of filing status. The tax you actually owe uses your filing-status threshold. The two can disagree in either direction, and the return settles it.
- Two earners who each stay under $200,000. Spouses earning $150,000 each have $300,000 of combined wages, $50,000 above the joint threshold. Neither employer withholds the extra tax, but the couple owes 0.9% of $50,000, which is $450, on their return.
- One earner above $200,000 with a non-working spouse. Wages of $220,000 trigger withholding of 0.9% on $20,000, which is $180. Filing jointly, the couple is under $250,000 and owes none of it, so the $180 comes back when they file.
Where the Social Security cap bites
Someone earning $250,000 from one employer stops paying Social Security after $184,500 of wages, which at a steady salary happens partway through the year: 184,500 divided by 250,000 is 73.8% of annual pay, so roughly the last quarter of the year's paychecks carry no Social Security tax. Medicare continues on every dollar, and the 0.9% addition starts once that employer has paid more than $200,000. A paycheck in December can therefore be larger than one in March with no raise at all.
8. Reading the Federal Tax Bracket and Payroll calculator against this guide
The Federal Tax Bracket and Payroll calculator uses the same 2026 thresholds printed in section 1 for single, married filing jointly and head of household filers, subtracts the matching standard deduction from the wages you enter, and adds the 6.2% Social Security tax on wages up to $184,500 and the 1.45% Medicare tax. Enter $75,000 as a single filer and it shows taxable income of $58,900 and federal tax of $7,670, the same as Example A. Three design choices still explain why it can differ from a real return.
- It takes the standard deduction only. Itemized deductions, the 2025 to 2028 senior, tips, overtime and car-loan deductions, pre-tax 401(k) deferrals and credits such as the child tax credit are not modeled, so anyone who claims them will see a federal figure that is too high.
- Its headline rate includes payroll tax. At $75,000 single it shows ($7,670 plus $5,737.50) divided by $75,000, or 17.88%. The separate "average income tax rate" line shows income tax alone, 10.23%, which is the figure section 5 of this guide reports.
- It does not model the 0.9% Additional Medicare Tax or any state or local income tax.
For a married couple, choose married filing jointly and enter combined wages: $150,000 gives taxable income of $117,800 and federal tax of $15,340, with $11,475 of FICA. Used this way, the tool is a quick check on the bracket arithmetic for wage earners who take the standard deduction.
Every example here starts from an annual gross figure. If your pay is quoted per hour, per week, or per pay period, the salary converter restates it as an annual amount, the hourly-to-salary calculator does the same from an hourly rate, and the salary to hourly overtime calculator helps size overtime pay before you separate out its qualified premium. The rest of the site's money tools are grouped on the finance calculators hub.
9. Common mistakes and where the simple answer breaks
"A raise will push me into a higher bracket and I'll take home less"
This is the most persistent bracket myth, and the arithmetic shows why it cannot happen under ordinary brackets. A higher rate applies only to the dollars above the threshold, never to the dollars below it.
Hypothetical: a single worker earns $66,500 in wages, which is $50,400 of taxable income, the exact top of the 12% band. A $1,000 raise lifts taxable income to $51,400.
- Income tax before the raise: $5,800. After: $5,800 plus 22% of $1,000, which is $6,020. The raise adds $220 of income tax.
- Payroll tax adds 7.65% of $1,000, which is $76.50.
- Take-home rises by $1,000 minus $220 minus $76.50, which is $703.50.
- The effective income tax rate moves from 8.72% to 8.92%. Nothing on the first $66,500 changed.
Where a raise can genuinely cost more than its bracket rate is outside the bracket table: a phase-out. Section 6 shows one. A single filer above $150,000 of modified AGI with qualified overtime loses $100 of deduction for each full $1,000 of extra income, which at a 24% rate is roughly another $24 of tax per $1,000. With the gradual Schedule 1-A phase-outs in this guide, take-home pay still rises; the gain is just smaller than the bracket rate alone suggests. Credits and programs that end abruptly at an income limit are a separate question this guide does not model.
Applying the top rate to the whole income
Multiplying $75,000 by 22% gives $16,500, more than double the correct $7,670. The marginal rate is for change, not for totals.
Using the brackets on gross pay
The thresholds are taxable income. Skipping the standard deduction overstates a single filer's tax by $16,100 times the marginal rate when gross and taxable income fall in the same band: $1,932 at 12% and $3,542 at 22%. When the deduction moves income across a threshold the gap is a blend; at $60,000 of wages, brackets on gross give $7,912 against the correct $5,020, an overstatement of $2,892.
Mixing up the tax year and the filing year
"2026 brackets" means income earned from January 1 to December 31, 2026, reported on the return filed in 2027. The return filed in early 2026 uses the 2025 tables and the $15,750, $31,500, and $23,625 standard deductions.
Assuming head of household is a choice
It is a status you qualify for, not one you pick for its better brackets. IRS Publication 501 (checked October 2026) sets three tests: you are unmarried or considered unmarried on the last day of the year, you paid more than half the cost of keeping up a home for the year, and a qualifying person lived with you in that home for more than half the year (a dependent parent does not have to live with you). A single parent who meets the tests saves real money, $1,072 before credits at $60,000 in Example C; a single person without a qualifying person must use the single tables.
Counting the whole overtime check as deductible
Only the premium portion qualifies, as Section 6 shows. A $9,000 overtime check at time-and-a-half carries a $3,000 qualified amount.
Expecting the new deductions to lower AGI
They are below-the-line deductions, taken after AGI. They lower taxable income, not AGI.
The marriage penalty at the very top
Two equal earners pay the same combined tax married or single through the 35% band. Above that, the joint 37% threshold of $768,700 is $512,500 below the $1,281,200 two single filers would have between them. Two spouses each earning $800,000 in wages pay $502,250.50 jointly against $492,000.50 as two singles: a $10,250 penalty, which is that $512,500 taxed at 37% instead of 35%.
Forgetting the Alternative Minimum Tax exists
The bracket tables are not the only federal computation. The IRS news release lists 2026 AMT exemptions of $90,100 for unmarried filers and $140,200 for joint filers, phasing out starting at $500,000 and $1,000,000. If your return involves items that the AMT treats differently from the regular tax, run the full computation in software rather than relying on the tables here.
Itemizers in the 37% bracket
The IRS release notes that the law made permanent the elimination of the old limitation on itemized deductions, but imposes a limit on the tax benefit of itemized deductions for taxpayers in the 37% bracket. If you itemize at that level, the benefit of an itemized deduction is no longer simply the deduction times 37%, so plan with the full rules or software.
10. A five-step check for your own 2026 estimate
Use this order; it mirrors the order of the return.
- Start from gross income and subtract pre-tax payroll items such as traditional 401(k) deferrals and health savings account contributions, plus any other above-the-line adjustments. The result approximates AGI.
- Subtract the standard deduction for your status, adding $1,650 or $2,050 per aged or blind condition. If itemized deductions are larger, use those instead.
- Subtract any Schedule 1-A deductions you qualify for after their phase-outs: senior, tips, overtime premium, new-vehicle loan interest. The result is taxable income.
- Apply the bracket table for your status using "tax at the bottom of the band plus rate times the excess." That is tax before credits.
- Subtract credits, then add payroll tax separately on wages: 6.2% to $184,500, 1.45% on all wages, and 0.9% above your filing-status threshold.
Then compare the total against what has been withheld year to date. Withholding is an estimate made by your employer; the return is where these numbers become final.
