The One Big Beautiful Bill Act: What Every Physician Must Know About Their Taxes in 2026

On July 4, 2025, the top federal income tax rate for physicians was saved from a scheduled increase that would have cost a cardiologist earning $750,000 an additional $19,500 per year. Without the One Big Beautiful Bill Act, the top marginal rate was set to jump from 37 percent to 39.6 percent on January 1, 2026 — the largest automatic tax increase in American history, affecting every physician earning above $731,200 (married filing jointly) or $626,350 (single). The OBBBA prevented that. But the law is 900+ pages long, and the provisions that help physicians financially exist alongside provisions that will fundamentally change medical student loan access, Medicaid coverage for your patients, and Medicare physician payment for the foreseeable future.

The One Big Beautiful Bill Act is the most significant piece of tax legislation affecting physicians since the Tax Cuts and Jobs Act of 2017. It was signed into law as Public Law 119-21 on July 4, 2025, using the budget reconciliation process — which means it passed with a simple Senate majority and touches every dimension of physician financial life simultaneously.

This article covers what actually changed, what it means in specific dollar terms for physicians at different income levels and practice settings, and what actions to take now. This is not a political article. The law has provisions that benefit physicians and provisions that harm their patients and future colleagues. We cover both with the same honesty we bring to every topic on this site.

One important caveat before everything else: the legislation is complex, its effects are highly individualized, and some provisions require specific elections or deadlines. The guidance here is educational. Work with a CPA who has physician client experience before making any tax election or major financial decision based on this law.

The Tax Cuts and Jobs Act of 2017 (TCJA) lowered tax rates, roughly doubled the standard deduction, capped the SALT deduction, and made dozens of other changes — all of which were scheduled to expire ("sunset") after 2025. Without any Congressional action, the entire 2017 tax framework would have reversed on January 1, 2026:

• Top tax rate from 37% back to 39.6%
• Standard deduction roughly halved
• SALT cap lifted back to unlimited (helping high earners in high-tax states)
• Estate tax exemption dropping from approximately $13.6 million back to approximately $5 million per person
• AMT hitting far more taxpayers

The OBBBA made most of these provisions permanent — preventing the tax cliff — while adding new provisions, changing some TCJA terms, and enacting major healthcare spending cuts and student loan restructuring. The net financial effect for most practicing physicians is modestly positive on the personal tax side and significantly negative in terms of patient coverage and future physician supply.

The single most financially significant provision for high-income physicians.

The OBBBA makes permanent the seven tax rates created by the TCJA, with the top tax rate remaining at 37 percent. Without the OBBBA, the top tax rate would have increased to 39.6% in 2026.

The dollar impact at different physician income levels:

Illustrative calculations on income in the top bracket above the 2026 threshold. Actual tax depends on filing status, deductions, and other income.

The income brackets where each rate applies have been adjusted for inflation. The 37 percent top rate applies to taxable income above approximately $751,600 for married filing jointly and $626,350 for single filers in 2026.

What this means practically: Every physician earning above these thresholds — every high-volume cardiologist, neurosurgeon, or cosmetic surgeon — keeps a meaningful amount more of their income annually than they would have under the pre-OBBBA scheduled sunset. The savings compound: a physician who operates in the 37 percent bracket for 25 more years of career saves $350,000 to $690,000 in lifetime income taxes compared to the 39.6 percent scenario, at today's income levels without accounting for income growth.

The OBBBA makes the TCJA's larger standard deduction permanent. Without the OBBBA, the standard deductions for every filing status would have been roughly halved starting in 2026.

2026 standard deduction amounts:

• Single filers: $15,750
• Married filing jointly: $31,500
• Head of household: $23,625

For most employed physicians who do not itemize — taking the standard deduction is the right choice when deductible mortgage interest, state income taxes, and charitable contributions combined do not exceed the standard deduction amount — this provision ensures that the large standard deduction remains available. The standard deduction is not affected by income level and does not phase out.

For physicians who itemize: The OBBBA made some changes to itemized deductions that are covered in the SALT and mortgage interest sections below. Whether you benefit more from itemizing or from the standard deduction depends on your specific deductible expenses and requires calculation for your situation.

This is the most misunderstood provision in the OBBBA for physician taxpayers — and the one most likely to disappoint physicians in high-tax states who read the headline without the fine print.

The headline: The SALT deduction cap was temporarily increased from $10,000 to $40,000 per household for tax years 2025 through 2029.

The reality for most physicians: The increased cap is not available to high-income households. The $40,000 SALT cap phases out for households with modified adjusted gross income above $500,000. The phaseout reduces the cap by $2 for every $1 of income above $500,000. At $520,000 MAGI, the effective SALT cap is $0.

The complication for single high earners is that the phaseout threshold is the same $500,000 MAGI whether filing alone or with a spouse. A single attending earning $600,000 is effectively back to the old $10,000 cap, same as the dual physician household pulling in $1.2 million combined.

What this means for physicians by income level:

The 2026 SALT provision is genuinely helpful for residents and early-career attendings in high-tax states whose income falls below the $500,000 MAGI threshold. For the majority of attending physicians earning above $500,000 in California, New York, or New Jersey, the SALT deduction remains effectively capped at $0 through the phaseout — the same result as the prior $10,000 cap for most purposes.

The pass-through entity tax (PTET) workaround:

The OBBBA preserves a workaround to the SALT cap for pass-through businesses, including partnerships, LLCs, S corporations, and sole proprietors. This workaround allows owners to potentially avoid the cap by making a pass-through entity tax (PTET) election, which shifts the owners' state tax burden from individuals to their pass-through entities. Even with the temporarily higher SALT cap, PTET elections are a valuable tax planning tool for eligible businesses in states with PTET laws — including California, New York, New Jersey, Connecticut, and many others.

For physicians who own practices structured as S-Corps, partnerships, or LLCs in states with PTET programs, this election can capture significant additional state tax deductions that are otherwise eliminated by the SALT cap. Confirm with your CPA whether your state has a PTET program and whether the election is still available for the 2026 tax year.

This is the section practice-owning physicians must read most carefully.

The Qualified Business Income (QBI) deduction under Section 199A allows owners of pass-through businesses — S-Corps, partnerships, LLCs, sole proprietors — to deduct 20 percent of their qualified business income from federal taxes. The OBBBA makes this deduction permanent.

The good news: The QBI deduction is now permanent and the phaseout range has been widened starting in 2026. Married physicians filing jointly can claim the full QBI deduction if taxable income stays below $394,600. The deduction phases out between that and $544,600 for joint filers (widened from the prior upper threshold).

The critical caveat for physician practice owners: Medicine is classified as a "Specified Service Trade or Business" (SSTB) under the tax code — the same category as law firms, consulting practices, and other professional services businesses. Physicians above the phaseout threshold cannot claim the QBI deduction on their clinical practice income.

What this means in practice:

• A physician whose taxable income is below $394,600 (MFJ): full 20% QBI deduction available
• A physician whose taxable income is between $394,600 and $544,600 (MFJ): partial QBI deduction
• A physician whose taxable income is above $544,600 (MFJ): no QBI deduction on clinical practice income

Since the majority of attending physicians in procedural specialties earn above $544,600 in total taxable income, the QBI deduction's practical benefit is concentrated among primary care physicians, cognitive specialists, and early-career attendings whose income has not yet crossed the phaseout threshold.

Where the QBI exception opens up: Practice owners with ancillary income, real estate holdings, or management company arrangements structured separately from clinical operations may still capture significant QBI benefits. A management services organization (MSO) that provides administrative services to the physician's clinical practice — and that is not itself classified as an SSTB — can generate QBI that the physician can deduct even above the income threshold. This is where entity structure becomes genuinely worth the CPA fees. As Physician on FIRE notes: "Ask specifically about QBI eligibility given your specialty and income level."

The OBBBA also introduced a $400 minimum QBI deduction for taxpayers with at least $1,000 of QBI, starting in 2026. For smaller pass-through structures that might otherwise get shut out entirely, this is a meaningful floor.

For the complete analysis of how QBI deduction applies to physician practices including the MSO structure and the S-Corp election mechanics, see our Locum Tenens Tax guide and the practice ownership section of our Physician Side Income guide.

This is the OBBBA provision with the most immediate actionable impact for physician practice owners.

100 percent bonus depreciation — the ability to immediately expense the full cost of eligible property in the year it is placed in service, rather than depreciating it over its useful life — was reinstated at 100 percent for assets placed in service after January 19, 2025.

Under the prior law, bonus depreciation had been phasing down: 80 percent in 2023, 60 percent in 2024, 40 percent in 2025. The OBBBA reversed the phasedown and restored full 100 percent immediate expensing.

What qualifies for 100% bonus depreciation:

• Medical equipment: diagnostic equipment, exam tables, surgical tools, monitoring equipment
• Practice technology: EHR systems, computers, tablets, servers
• Real estate components subject to cost segregation (5-year and 15-year property)
• Physician-owned ASC or medical office building improvements
• Equipment for locum tenens or home office setup

The dollar impact for a physician practice owner:

A family medicine physician who purchases a new $150,000 digital X-ray system and $50,000 in examination equipment for a new practice location in 2026:

• Without 100% bonus depreciation: depreciated over 5 to 7 years at $20,000 to $28,570 per year in deductions
• With 100% bonus depreciation: $200,000 immediate deduction in 2026

At a 37 percent marginal rate: $200,000 immediate deduction generates $74,000 in immediate federal tax savings — compared to $7,400 to $10,571 in the first year under straight-line depreciation. The physician captures the entire tax benefit in year one rather than spreading it over 5 to 7 years.

The cost segregation amplifier: For physicians who own real estate — office buildings, medical condos, ASC facilities — 100 percent bonus depreciation combined with a cost segregation study produces the largest available first-year tax deduction in physician practice ownership. A cost segregation study identifies building components eligible for 5-year or 15-year depreciation (rather than the standard 39-year commercial real estate schedule), then applies 100 percent bonus depreciation to those components in year one. The result: first-year paper losses in the six figures that can be deducted against clinical income for physicians who qualify as real estate professionals or who use the short-term rental loophole.

For the complete analysis of how bonus depreciation interacts with physician real estate investment and the passive activity loss rules that limit its applicability, see our Rental Real Estate for Physicians guide.

For the vast majority of physician families, the OBBBA has effectively eliminated federal estate tax concerns.

One notable change to estate planning is that the OBBBA permanently increased the federal lifetime estate tax exemption to $15 million per person ($30 million for married couples) starting in 2026. That figure will be adjusted annually for inflation beginning in 2027. Without the OBBBA, the lifetime exemption was scheduled to drop to approximately $5 million per person (inflation-adjusted) after 2025.

The practical impact:

A married physician couple who builds $10 million in combined net worth over a 30-year career — which is excellent wealth accumulation but not uncommon for high-income proceduralists with practice equity and real estate — would have faced potential estate tax exposure under the pre-OBBBA $5 million per person framework. Under the $30 million married couple exemption, they face no federal estate tax regardless of how that $10 million grows over the remainder of their lives.

For the physician with truly significant accumulated wealth — PE transaction proceeds, large practice equity, substantial real estate portfolios — the $15 million per person exemption pushes the federal estate tax threshold above what even very high-net-worth physicians typically accumulate in clinical careers.

The state estate tax caveat: The OBBBA addresses only federal estate taxes. Several states maintain their own estate tax at dramatically lower thresholds — Massachusetts at $2 million, Oregon at $1 million, Washington at $2.193 million — that are not affected by the federal exemption increase. Physicians in these states still face meaningful state estate tax exposure despite the federal OBBBA change. The complete state-by-state estate tax analysis is in our Estate Planning for Physicians guide.

What estate planning actions remain necessary:

Even with a $15 million federal exemption, physicians still need the five foundational estate planning documents — revocable living trust, will, durable power of attorney, healthcare directive, and HIPAA authorization — for the non-tax reasons these documents serve: probate avoidance, privacy, incapacity planning, guardian designation for minor children, and beneficiary designation coordination. Estate planning is not only about taxes. The elimination of the federal estate tax concern simply removes one layer of urgency — it does not eliminate the planning need.

This is the OBBBA provision that will have the longest lasting impact on the physician workforce — and the one most likely to affect current medical students immediately.

The OBBBA makes several significant changes to federal student loan programs, effective July 1, 2026 and beyond:

Graduate PLUS Loans eliminated: Federal Direct PLUS Loans for graduate and professional students are eliminated effective July 1, 2026. Medical students who have been using Grad PLUS loans to fund years three and four of medical school — historically a critical source of funding for the tuition amount exceeding Direct Unsubsidized Loan limits — lose access to this program. As AMA notes, these changes make the high cost of medical school even more unaffordable and will surely exacerbate an already alarming physician shortage.

Annual and total loan caps: Unsubsidized federal loans for professional students are capped at $50,000 per year with a total professional school cap of $200,000. Including undergraduate debt, the total federal borrowing cap is $257,500. Medical school tuition at many private institutions runs $60,000 to $70,000 per year — meaning a student at a private medical school whose tuition exceeds the new annual cap must fund the difference through private loans (which carry higher rates and lack federal protections) or institutional financing.

Repayment options reduced to two: New federal student loan borrowers are limited to only two repayment options: a fixed standard plan or the new Repayment Assistance Plan (RAP). IBR, PAYE, ICR, and SAVE — all of the income-driven repayment plans that existing borrowers use — are eliminated for new borrowers.

The Repayment Assistance Plan (RAP) — why it is problematic for physicians:

The RAP begins in July 2026 and calculates payments based on AGI — not discretionary income as IBR does. For anyone making more than $100,000, the payment is limited to 10 percent of income. The repayment period is 30 years.

A physician earning $350,000 in attending income under RAP would owe approximately $35,000 per year in loan payments ($2,917 per month). Under IBR on a $350,000 income, the physician pays the 10 percent of discretionary income formula which also produces high payments — but IBR has a 20-year forgiveness term (or 10 years under PSLF) versus RAP's 30-year term. The RAP will almost definitely be a bad plan for most doctors to be enrolled in for 30 years, and for high-earning physicians, could result in extremely high payments even for those going for PSLF.

The critical action item for current borrowers:

These changes apply to new borrowers after July 1, 2026. Current medical students and physicians with existing federal loans are not subject to the new loan caps or the RAP requirement — they remain on their existing plans. However, Parent Plus Loan borrowers need to consolidate their loans and enroll in the ICR plan by June 30, 2026, to be eligible for IDR plans. If you are a Parent Plus borrower or advising a family member who is, this deadline is urgent.

The REDI Act provision — a partial win for residents:

The OBBBA includes a modified version of the "Resident Deferred Interest (REDI) Act," allowing deferment of loan repayment with no interest accrual for up to four years during residency. For the new repayment framework under RAP, this deferment during residency — with no interest accruing — is a meaningful protection for new borrowers starting medical school after July 2026. It does not, however, address the fundamental problem that the loan caps may make private medical school financially impossible for many students without substantial family wealth.

For current physicians navigating their existing federal loan strategy, see our Physician Student Loan Forgiveness guide, PSLF vs. Refinancing guide, and Student Loan Refinancing guide.

The OBBBA includes a 2.5 percent conversion factor update for Medicare physician payments for 2026 only. This is a one-year temporary increase, not a permanent fix.

This provision gets a brief section because it affects physician revenue but is not a tax planning issue — it is a reimbursement issue. Here is the honest context:

Two decades of declining Medicare physician payments — in inflation-adjusted terms — have produced a 26 percent cumulative real reduction in physician reimbursement since 2001, per the AMA. The 2.5 percent 2026 update does not meaningfully address this structural problem. The House version of the OBBBA would have provided a permanent inflation-adjusted baseline update — that provision was removed in the Senate.

The practice implication: The 2.5 percent conversion factor increase modestly improves 2026 wRVU-based compensation for employed physicians whose contracts use the Medicare conversion factor as their reference rate. However, this increase is for 2026 only. Physicians in multi-year employment contracts that reference the Medicare conversion factor should confirm with their employer how the temporary 2026 increase interacts with their contract's conversion factor provisions.

The IRS issued Notice 2026-05 expanding Health Savings Account availability under the OBBBA. Specifically, the OBBBA expanded the definition of qualifying high-deductible health plans and expanded eligible HSA expenses — changes that increase the universe of physicians who can contribute to an HSA.

2026 HSA contribution limits:

• Individual coverage: $4,400
• Family coverage: $8,750
• Catch-up contribution (age 55+): additional $1,000

What changed: The OBBBA expanded HSA eligibility to include certain Medicare Advantage plans and other arrangements that were previously excluded. If you are on employer-sponsored health insurance that was not previously HSA-eligible but you believe the new rules might change this, confirm with your benefits administrator whether your plan now qualifies.

The HSA remains the only triple-tax-advantaged account available to physicians: contributions are tax-deductible (or pre-tax through payroll), growth is tax-free, and withdrawals for qualified medical expenses are tax-free. The physician who maximizes HSA contributions and invests the balance rather than spending it creates a supplemental retirement account that can reach $300,000 to $500,000 over a career of physician-level contributions compounding at market rates.

For the complete HSA strategy including how to use it as a stealth retirement account, see our HSA Strategy for Physicians guide.

While this article focuses on physician financial planning, the OBBBA's Medicaid provisions affect physician revenue in ways that belong in any honest accounting of the law's impact.

The Congressional Budget Office estimates that Medicaid would be cut by over $1 trillion through 2034 through work requirements, changes to provider taxes, and other provisions, leaving an estimated 10 million or more people uninsured by that date. States are effectively barred from establishing any new provider taxes or increasing rates on existing ones — a financing mechanism that most states use to fund their Medicaid programs.

For physicians who serve significant Medicaid populations — family medicine in rural or urban underserved areas, pediatricians, psychiatrists treating publicly insured patients, emergency physicians — these changes will reduce the insured patient base and potentially affect clinical volume and revenue. The complete AMA analysis is available at the AMA's OBBBA resource page.

This is not a political statement. It is a financial planning reality for physicians whose practice revenue depends on Medicaid reimbursement.

The OBBBA is now law. The provisions above are in effect. Here is the physician-specific action list organized by urgency.
