A single attending earning $300,000 in 2026 is "in the 35% bracket" — and will pay an effective federal income tax rate of about 22.7%. Both numbers are correct. Confusing them is the most common tax error physicians make, and it is not a harmless one: it distorts decisions about extra shifts, , retirement contributions, and contract negotiations, usually in the direction of leaving money on the table.
The mechanics take ten minutes to internalize and pay off for the rest of your career. This article lays out the exact 2026 federal brackets, works the $300,000 example to the dollar, and then runs the arithmetic on the myth that refuses to die in every physician lounge: "the raise will bump me into a higher bracket, so I'll take home less."
A quick scope note: everything below is federal income tax on ordinary income. Payroll taxes (Social Security and Medicare) and state income tax stack on top, and we will put numbers on those for completeness — but the marginal-vs-effective logic is the load-bearing concept, and it lives in the federal brackets.
The 2026 federal brackets
Brackets apply to taxable income — your gross income minus pre-tax deductions (/ deferrals, contributions, pre-tax premiums) and minus the standard or itemized deduction. The 2026 standard deduction is $16,100 single / $32,200 married filing jointly.
Single filers, 2026:
| Rate | Taxable income |
|---|---|
| 10% | $0 – $12,400 |
| 12% | $12,400 – $50,400 |
| 22% | $50,400 – $105,700 |
| 24% | $105,700 – $201,775 |
| 32% | $201,775 – $256,225 |
| 35% | $256,225 – $640,600 |
| 37% | above $640,600 |
Married filing jointly, 2026:
| Rate | Taxable income |
|---|---|
| 10% | $0 – $24,800 |
| 12% | $24,800 – $100,800 |
| 22% | $100,800 – $211,400 |
| 24% | $211,400 – $403,550 |
| 32% | $403,550 – $512,450 |
| 35% | $512,450 – $768,700 |
| 37% | above $768,700 |
(Figures per IRS Rev. Proc. 2025-32, the official inflation adjustments for tax year 2026.)
The single most important fact about this table: the rates apply to slices, not to your whole income. Crossing into the 32% bracket does not re-tax your first dollar at 32%. It means dollars above $201,775 are taxed at 32%; every dollar below that line keeps its lower rate forever. Your income fills the brackets like a bucket fills from the bottom — the top rate only ever touches the top water.
- = the rate on your next dollar (the bracket your top slice sits in).
- Effective rate = total tax ÷ total income — the blended average across all slices.
For every physician, the effective rate is far below the marginal rate, because the first $200,000+ of taxable income travels through the 10/12/22/24% slices on the way up.
The $300,000 attending, worked to the dollar
A single hospitalist with $300,000 of W-2 wages, no pre-tax retirement contributions (we will fix that in a moment), taking the standard deduction:
Taxable income: $300,000 − $16,100 = $283,900
Example calculation
2026 federal tax, slice by slice (single, $283,900 taxable):
| Slice | Width | Rate | Tax |
|---|---|---|---|
| $0 – $12,400 | $12,400 | 10% | $1,240 |
| $12,400 – $50,400 | $38,000 | 12% | $4,560 |
| $50,400 – $105,700 | $55,300 | 22% | $12,166 |
| $105,700 – $201,775 | $96,075 | 24% | $23,058 |
| $201,775 – $256,225 | $54,450 | 32% | $17,424 |
| $256,225 – $283,900 | $27,675 | 35% | $9,686 |
| Total | $68,134 |
- Marginal rate: 35% (the top slice)
- Effective rate on gross income: $68,134 ÷ $300,000 = 22.7%
- Effective rate on taxable income: 24.0%
So the physician "in the 35% bracket" sends the IRS 22.7 cents of the average dollar — but 35 cents of the next dollar. Both numbers are useful, for different jobs:
- The effective rate answers budgeting questions: what is my actual take-home, what do I really pay.
- The marginal rate answers decision questions: what is one more shift worth after tax, what does a $24,500 retirement deferral save, what does $20,000 of moonlighting net.
This is why pre-tax retirement contributions punch above their weight for attendings. That same physician deferring the full $24,500 into a 403(b) reduces taxable income to $259,400 — and every one of those deferred dollars would have been taxed in the 35% slice. Federal savings: $24,500 × 35% = $8,575, cutting the bill from $68,134 to $59,559. Deductions come off the top of your income at the marginal rate; income gets averaged, deductions don't.
For the full cash-flow picture, add payroll taxes: Social Security at 6.2% on wages up to the 2026 wage base of $184,500 ($11,439), Medicare at 1.45% on everything plus an additional 0.9% on wages above $200,000 (single) — about $5,250 on $300,000. Total federal income + payroll: roughly $84,800, or 28.3% of gross, before state tax. Real, but still nowhere near "35% of everything."
The raise myth, killed with arithmetic
The claim: "If the raise pushes me into a higher bracket, I could take home less." It is arithmetically impossible under the bracket structure, and one worked example shows why.
A single physician with taxable income of $201,000 — $775 below the 32% bracket line — is offered a $5,000 raise, landing at $206,000 taxable. The lounge version of events: "that pushes me into the 32% bracket."
Example calculation
Tax at $201,000 taxable: $17,966 (tax through the 24% bracket floor) + ($201,000 − $105,700) × 24% = $17,966 + $22,872 = $40,838
Tax at $206,000 taxable: $41,024 (tax through the 32% bracket floor at $201,775) + ($206,000 − $201,775) × 32% = $41,024 + $1,352 = $42,376
Extra tax on the $5,000 raise: $1,538. Extra take-home: $3,462.
Only the $4,225 above the bracket line was taxed at 32%; the first $775 of the raise was taxed at 24%; and not one dollar of the existing $201,000 changed treatment.
The "raise" that crossed a bracket line raised this physician's effective rate from 20.3% to 20.6% of taxable income — a rounding-error change — while delivering 69 cents of every new dollar. There is no income level in the bracket table at which earning more federal-taxable income reduces after-tax income. None.
Important
The myth survives because adjacent things are real. Cliffs exist outside the bracket table: certain credits and deductions phase out over income ranges, the additional 0.9% Medicare tax starts at $200,000 of wages (single), the 3.8% net investment income tax applies above $200,000 MAGI, and the Roth IRA contribution phase-out runs $153,000–$168,000 single / $242,000–$252,000 MFJ in 2026 (solved by the backdoor Roth, not by earning less). These raise the marginal cost of income at certain thresholds by a few points — they never make extra income a net loss. Declining shifts "to stay in a lower bracket" is always a mistake; the correct response to a high marginal rate is to shelter income, not refuse it.
The decision-grade takeaway: evaluate every extra shift, stipend, and moonlighting opportunity at your marginal rate, and evaluate your lifestyle and budget at your effective rate. A $20,000 moonlighting opportunity for the $300,000 hospitalist is worth roughly $20,000 × (1 − 35% − 2.35% Medicare) ≈ $12,500 after federal tax — materially less than $20,000, far more than zero, and exactly the kind of number you should compute before deciding whether the weekend is worth it.
Where physicians actually sit in the table
A few orienting observations for 2026:
Most single attendings top out at 32–35%. A single physician hits the 32% bracket at $201,775 taxable (about $218,000 gross with only the standard deduction) and 35% at $256,225 taxable (~$272,000 gross). The 37% bracket, at $640,600 taxable, is the territory of high-earning specialists and physicians with substantial .
Marriage moves the lines — in both directions. The MFJ brackets are exactly double the single brackets through the 32% bracket floor ($403,550 = 2 × $201,775), so a physician married to a lower earner often sees their marginal rate fall after marriage. But the 35% MFJ bracket starts at $512,450 — exactly 2× the single threshold's $256,225 — while the 37% bracket starts at $768,700, less than double $640,600. Two $400,000 physicians filing jointly pay more than they would as two single filers at the top: the marriage penalty is real, but only at the highest slice.
The deferral stack works at the top slice. For a married physician household at $450,000 gross (taxable ~$417,800, marginal 32%), every pre-tax dollar — two $24,500 employer-plan deferrals, an $8,750 family HSA — saves 32 cents federal until taxable income drops to $403,550, then 24 cents. The brackets are precisely why the standard physician advice is "max the pre-tax accounts first": the deduction is harvested at 32–35% now, and withdrawn through the 10/12/22/24% slices in retirement.
Common questions
What is the difference between marginal and effective tax rate?
Marginal is the rate on your next dollar — the bracket your top slice of taxable income occupies. Effective is total tax divided by total income, blending every slice. A 2026 single attending at $300,000 gross: 35% marginal, ~22.7% effective. Use marginal for decisions about earning or sheltering one more dollar; use effective for understanding your real total burden.
Can a raise ever reduce my take-home pay?
Not through the tax brackets — only dollars above each bracket line are taxed at the higher rate, so extra income always yields extra take-home. Narrow exceptions live outside the brackets (benefit cliffs, credit phase-outs), and for attending-income physicians these change the marginal rate by single percentage points at worst. They are reasons to plan, never reasons to decline income.
Do bonuses get taxed at a higher rate?
No — they get withheld at a flat supplemental rate (typically 22%) that often differs from your true marginal rate, then settle up at your actual brackets when you file. A $40,000 signing bonus withheld at 22% will generate additional tax due at filing for a 35%-marginal attending. The withholding is not the tax.
Are the brackets applied to my salary or my taxable income?
Taxable income: gross income minus pre-tax payroll items (retirement deferrals, HSA, pre-tax premiums) and minus the standard deduction ($16,100 single / $32,200 MFJ in 2026) or itemized deductions. This gap is why a $300,000 salary produces $283,900 — or with a maxed 403(b), $259,400 — of taxable income.
What about state taxes?
They stack on top of everything above, from 0% (TX, FL, TN, WA, NV, and four others) to 13.3% at the top in California — for a high-earning physician, the state line on the offer letter can matter as much as $30,000+ of salary. Most state systems are either flat (Pennsylvania, 3.07%) or progressive with their own brackets; the marginal-vs-effective logic applies identically.
What to do next
- Pull your most recent tax return and compute your actual effective rate: total tax (Form 1040, line 22) ÷ total income. Most attendings guess high by 8–12 points.
- Find your marginal rate in the 2026 tables above using projected taxable income — this is the number for every "is it worth it" decision this year.
- Multiply your unfilled pre-tax space ($24,500 employer plan, $4,400/$8,750 HSA, 457(b) if available) by your marginal rate. That product is the check you are currently writing to the IRS voluntarily.
- Re-price any extra shifts or moonlighting you have been evaluating at gross value — redo the math at your marginal rate and decide with the real number.
- If your household sits near a bracket line ($201,775 single / $403,550 MFJ taxable), note that pre-tax contributions can pull your top slice back into the lower bracket — a deferral decision worth making deliberately in December rather than discovering in April.
The paycheck decoder in Attending Financial does the slice-by-slice math on your actual stub — your true marginal rate, your effective rate, and what each pre-tax election is really saving you — so the next time the lounge debate starts, you can settle it with your own numbers.
