You finish training into one of the steepest sections of the federal tax code. An attending income between $300,000 and $450,000 lands squarely in the 32 and 35 percent brackets, sits above every phase-out that matters, and — starting with the 2026 tax year — meets a rewritten itemized-deduction landscape under Pub. L. 119-21 (the July 2025 reconciliation act, commonly called OBBBA). This guide is the orientation: what the 2026 numbers actually are, where your dollars go, which decisions are yours to make, and when in the calendar each one happens. Every figure below comes from the 2026 inflation adjustments in Rev. Proc. 2025-32, IRS Notice 2025-67, or the statute itself, and each is dated — tax writing without a rule year attached is how physicians end up planning around numbers that expired two Congresses ago.
Marginal and effective are different numbers, and confusing them costs real decisions
The federal income tax has seven rates in 2026 — 10, 12, 22, 24, 32, 35, and 37 percent — applied to slices of taxable income, not to the whole of it. Per Rev. Proc. 2025-32, the 2026 brackets are:
| Rate | Single — taxable income | Married filing jointly — taxable income |
|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 |
| 12% | $12,400 – $50,400 | $24,800 – $100,800 |
| 22% | $50,400 – $105,700 | $100,800 – $211,400 |
| 24% | $105,700 – $201,775 | $211,400 – $403,550 |
| 32% | $201,775 – $256,225 | $403,550 – $512,450 |
| 35% | $256,225 – $640,600 | $512,450 – $768,700 |
| 37% | over $640,600 | over $768,700 |
Two numbers fall out of this table for any income you plug in. Your is the rate on the last dollar — the number that prices every decision at the edge: one more shift, one more dollar of deferral, one more dollar of charitable giving. Your effective rate is total tax divided by income — the number that describes your year but prices nothing. Plan with the marginal rate; budget with the effective rate; never swap them.
Example calculation
Assumptions, stated explicitly: single hospitalist, $300,000 of W-2 wages, no pre-tax deferrals yet, standard deduction of $16,100 (Rev. Proc. 2025-32), no other income.
Taxable income: $300,000 − $16,100 = $283,900
- 10% × $12,400 = $1,240
- 12% × $38,000 = $4,560
- 22% × $55,300 = $12,166
- 24% × $96,075 = $23,058
- 32% × $54,450 = $17,424
- 35% × $27,675 = $9,686
Federal income tax: $68,134 Marginal rate: 35% · Effective rate on gross income: 22.7%
Example calculation
Assumptions, stated explicitly: married couple filing jointly, $450,000 of combined W-2 wages (a $300,000 anesthesiologist and a $150,000 spouse), standard deduction of $32,200, no pre-tax deferrals yet.
Taxable income: $450,000 − $32,200 = $417,800
- 10% × $24,800 = $2,480
- 12% × $76,000 = $9,120
- 22% × $110,600 = $24,332
- 24% × $192,150 = $46,116
- 32% × $14,250 = $4,560
Federal income tax: $86,608 Marginal rate: 32% · Effective rate on gross income: 19.2%
Notice what the two examples show. The single physician at $300,000 pays a higher effective rate than the married couple at $450,000, because the joint brackets are roughly twice as wide. And in both cases the marginal rate — 35 and 32 percent — is the price tag on every planning decision that follows in this guide. The mechanics of how brackets stack, including where capital gains slot in, are worked through in the tax brackets module; the current-year numbers live in the 2026 physician tax brackets reference.
One consequence worth internalizing: a raise never costs you money. Crossing from $403,550 to $403,551 of joint taxable income moves exactly one dollar into the 32 percent bracket; the other $403,550 is taxed precisely as before. The places where an extra dollar genuinely costs more than its bracket rate are phase-outs — and 2026 adds a significant one for itemizers above $505,000, covered below.
The deferral stack: up to $57,750 can leave your taxable income before you think about itemizing at all
Deductions get the attention; deferrals do the work. For an employed physician the 2026 stack, per IRS Notice 2025-67 and Rev. Proc. 2025-19, is:
| Account | 2026 employee limit | Notes |
|---|---|---|
| 403(b) or | $24,500 | Elective deferral limit under §402(g); catch-up $8,000 at 50+, $11,250 at 60–63 |
| 457(b) | $24,500 | A separate limit — it does not share the $24,500 with your 403(b) |
| $4,400 / $8,750 | Self-only / family, requires a qualifying high-deductible plan; +$1,000 at 55+ | |
| Total | up to $57,750 | Family HSA, both employer plans, under age 50 |
The 457(b) line is the one physicians miss. Hospital and academic employers commonly offer both a 403(b) and a 457(b), and the limits are independent — a full second $24,500 of deferral that most eligible physicians leave unused. At a 35 percent marginal rate, each maxed account is worth $8,575 of federal tax not paid this year; the full $57,750 stack removes roughly $20,200 of 2026 federal income tax for the single physician in the example above, before any state effect. Governmental versus non-governmental 457(b) plans carry very different creditor and distribution rules — that distinction, and the order in which to fill every account, is the subject of the retirement account map.
Above the employee limits sits the §415(c) ceiling — $72,000 in 2026 for total contributions to a defined-contribution plan including and after-tax contributions — which matters if your plan permits after-tax contributions with in-plan conversion. And the deferral conversation changes shape entirely with , where a solo defined-contribution plan lets you control both sides of the $72,000. The broader inventory of what legitimately reduces a physician tax bill — and what merely gets marketed that way — is in legitimate tax reduction.
Before any itemizing analysis, an employed physician household with access to a 403(b), a 457(b), and a family HSA can remove up to $57,750 from 2026 taxable income at its marginal rate — the highest-certainty tax planning available to you, requiring no structure more exotic than payroll elections.
Itemizing after OBBBA: the $32,200 hurdle is suddenly clearable — until your income takes the ladder away
For most of the past decade, attending physicians took the standard deduction by default: the state-and-local-tax (SALT) deduction was capped at $10,000, and few physicians without large mortgages could beat the standard amount. Pub. L. 119-21 rewrote this for 2026 in three moves, and all three point in different directions.
First, the SALT cap rises to $40,400 for 2026 ($20,200 married filing separately). A physician in a high-income-tax state can now have SALT alone clear the $32,200 joint standard deduction.
Second, the raised cap phases down above $505,000 of modified AGI. The cap shrinks by 30 cents for every dollar of over $505,000, but never below the old $10,000 floor — which it reaches at roughly $606,333 of MAGI.
Example calculation
Assumptions, stated explicitly: married couple filing jointly, $560,000 MAGI, $45,000 of state income and property taxes paid, 2026 rules.
- Excess MAGI: $560,000 − $505,000 = $55,000
- Cap reduction: 30% × $55,000 = $16,500
- 2026 SALT cap: $40,400 − $16,500 = $23,900
- Deductible SALT: the lesser of $45,000 paid and the $23,900 cap = $23,900
Inside the $505,000–$606,333 window, each extra dollar of income also destroys $0.30 of deduction. At a 35% marginal rate that adds roughly 10.5 points: the effective marginal rate on income in this window is about 45.5%, before state tax.
Important
The phase-down window is the single most expensive stretch of income on a 2026 physician return. If your household MAGI is projected to land between $505,000 and about $606,000 and you itemize, income-shifting tools you already have — 403(b), 457(b), HSA, pre-tax 401(a) contributions — are worth roughly 45 cents on the dollar there, not 35. Model this before December, not at filing.
Third, charitable deductions acquire a floor and a ceiling. Starting in 2026, itemizers may deduct only the portion of charitable gifts exceeding 0.5 percent of AGI, and the tax value of itemized deductions for those in the 37 percent bracket is capped at 35 cents per dollar. A couple with $450,000 of AGI giving $10,000 deducts $7,750 of it ($10,000 minus the $2,250 floor). Non-itemizers get a small consolation: a new above-the-line charitable deduction of up to $1,000 single / $2,000 joint. The floor rewards bunching — concentrating two or three years of giving into one tax year clears the 0.5 percent hurdle once instead of repeatedly.
So who itemizes in 2026? Roughly: a physician household under $505,000 MAGI in a state with a meaningful income tax, or with substantial mortgage interest, will likely clear $32,200 and itemize — often for the first time since 2017. Above $606,000 MAGI, the SALT cap is back to $10,000 and the standard deduction frequently wins again unless mortgage interest and bunched charitable giving carry the load. In the window between, run both numbers.
FICA does not care about your deductions
Everything above concerns the income tax. Payroll tax runs on its own track, ignores your deferrals for Social Security and Medicare purposes, and at attending income includes a surtax many physicians first meet as a surprise balance due.
Three pieces, 2026 numbers:
- Social Security (OASDI): 6.2 percent of wages up to the $184,500 wage base (SSA, October 2025 announcement). Maximum employee-side tax: $11,439. Your employer pays the same again.
- Medicare: 1.45 percent of all wages, no cap.
- Additional Medicare Tax: 0.9 percent of wages above $200,000 single / $250,000 married filing jointly (IRC §3101(b)(2); IRS Topic 560). These thresholds are statutory and have never been indexed — they have sat still since 2013 while physician incomes have not.
For the single physician at $300,000: $11,439 + $4,350 + $900 = $16,689 of employee-side payroll tax, on top of the $68,134 of income tax computed earlier — an all-in federal effective rate of 28.3 percent.
Important
The Additional Medicare Tax has a withholding trap built for two-physician couples. Employers must withhold the 0.9 percent only on wages above $200,000 at that job, regardless of filing status. A couple earning $300,000 and $150,000 owes the surtax on $200,000 of combined wages ($1,800), but withholding covers only $900 of it — the second employer never crosses $200,000 and withholds nothing. The remainder arrives as a balance due on Form 8959. The same mechanic bites a physician with two jobs that each stay under $200,000. Fix it with an extra-withholding line on Form W-4, not by ignoring it.
Note also the two-employer Social Security quirk in the other direction: each employer withholds 6.2 percent up to $184,500 independently, so a physician who changes jobs mid-year often has excess OASDI withheld — recovered automatically as a credit on the Form 1040, but only if the return is prepared correctly.
W-2, 1099, or both: the architecture decision that precedes every other one
Everything in this guide so far assumed W-2 employment: taxes withheld per paycheck, payroll tax split with an employer, retirement limited to the employer's plan menu. Independent-contractor (1099) income inverts each of those. Nothing is withheld — you remit quarterly yourself. You pay both halves of payroll tax as self-employment tax, partially offset by a deduction for the employer-equivalent portion. And you gain the ability to open your own retirement plan and deduct legitimate business expenses against the income. For an attending with a moonlighting side income, the practical consequences — the set-aside percentages, the quarterly deadlines, the safe harbors — are worked through in the quarterly estimated tax guide; the full W-2-versus-1099 comparison, including when a 1099 rate is genuinely higher and when it only looks higher, is part of legitimate tax reduction. The one-line version: a 1099 dollar is neither better nor worse than a W-2 dollar until you have priced the payroll tax, the benefits you now buy yourself, and the retirement space you gain.
Filing status is a decision, not a default
Married physicians file jointly by default, and jointly is usually right: the brackets are wider, and married-filing-separately status forfeits several benefits outright. But two physician-specific situations justify running the numbers both ways. The first is income-driven student loan repayment — filing separately can exclude a spouse's income from the payment calculation, and for a physician pursuing the payment savings can exceed the tax cost of separate filing, sometimes by five figures a year. The second is the rare case where separate filing changes a phase-out outcome. This is a genuine two-variable optimization — tax bill versus loan payment — and it should be recomputed every year, because both the loan rules and your incomes move. The comparison framework is covered in the guides linked from reducing physician taxes.
The attending tax calendar: twelve months, six real deadlines
Tax season is not a season; it is a loop. Here is the 2026 loop for a physician on a calendar tax year:
| Date | What happens |
|---|---|
| January 15, 2026 | Q4 2025 estimated payment due (if you owe estimates) |
| Late January – February | W-2s and most 1099s arrive; brokerage consolidated forms often mid-February with corrections after |
| April 15, 2026 | 2025 return or extension due; payment due regardless; Q1 2026 estimate due; last day for 2025 IRA and HSA contributions |
| June 15, 2026 | Q2 2026 estimate due |
| September 15, 2026 | Q3 2026 estimate due; extended partnership/S-corp K-1s arrive |
| October 15, 2026 | Extended 2025 individual return due |
| December 2026 | The planning month: verify 403(b)/457(b) will hit $24,500 each; check Additional Medicare and total withholding against the safe harbor; bunch or complete charitable gifts; execute steps; review W-4 for next year |
The December row is the one that pays. Every lever in this guide — the deferral stack, the phase-down window, the charitable floor, the withholding cure — is adjustable in December and merely reportable in April.
Common questions
My marginal rate is 35 percent — does that mean the government takes 35 percent of my income?
No. The 35 percent applies only to income inside that bracket slice. The single physician at $300,000 computed above pays an effective federal income tax rate of 22.7 percent, and 28.3 percent including payroll taxes. The 35 percent figure is still the number that prices decisions — every dollar you defer into a 403(b) saves 35 cents — but it does not describe your total bill.
Should I itemize in 2026?
Compute three numbers: your SALT payments (capped at $40,400, less any phase-down above $505,000 MAGI), your mortgage interest, and your charitable gifts minus 0.5 percent of AGI. If the sum beats $16,100 single or $32,200 joint, itemize. Physicians in income-tax states below the phase-down threshold will often itemize in 2026 after years of taking the standard deduction; physicians above roughly $606,000 MAGI will often be back at the standard deduction.
Is there anything I can do about payroll taxes?
On W-2 wages, essentially no — FICA applies before every deduction you control. The margins are structural: self-employment income above the $184,500 wage base escapes the 12.4 percent OASDI component (only the 2.9 + 0.9 percent Medicare pieces apply), and an S-corp election on substantial 1099 income changes the payroll tax base, with strict reasonable-compensation rules. Both belong to the 1099 architecture conversation, not to a W-2 paycheck.
Do these numbers change every year?
Most do. Brackets, the standard deduction, deferral limits, the wage base, and the SALT cap adjust annually; the Additional Medicare Tax thresholds do not. Rebuild your assumptions each fall when the IRS publishes the next revenue procedure — this guide is built on Rev. Proc. 2025-32 and Notice 2025-67 and is accurate for tax year 2026.
What to do next
- Pull your last pay stub and your most recent Form 1040, and compute both rates: marginal (from the table above) and effective (total tax ÷ total income). Ten minutes, no cost.
- Ask HR one question: does your employer offer a 457(b) in addition to the 403(b), and is it governmental? The answer may be worth $24,500 of deferral space.
- Set your 2026 payroll elections to reach $24,500 in the 403(b)/401(k) by December, and fund the HSA to $4,400 or $8,750 if you hold a qualifying plan.
- Project your household MAGI. If it lands between $505,000 and $606,000, price every additional pre-tax dollar at roughly 45 cents of tax saved and act accordingly.
- Sum your projected SALT, mortgage interest, and charitable giving against $32,200 (joint) to decide the itemizing question before December, while bunching is still possible.
- If you have any 1099 income, set up the quarterly estimate system now — the quarterly guide is the next article in this series.
The pattern in all of it: the tax code prices your decisions at the margin, publishes the prices every October, and rewards the physician who reads them once a year. The protocol above works with or without us. This is education, not individualized financial advice.
