Tax Planning for Physicians (2026): 12 Strategies That Lower Your Bill, and What Changed This Year

Most physician tax planning is less exotic than the internet suggests. An employed physician can't deduct much beyond what everyone else can, so the savings come from three places: shifting income into tax-advantaged accounts, timing deductions so they count, and avoiding a handful of expensive mistakes. Physicians with 1099 income or a practice have more options, and more ways to get them wrong.

This guide covers 12 strategies for 2026, starting with what the 2025 tax law (the One Big Beautiful Bill Act, which the IRS now calls the Working Families Tax Cuts) changed. Every figure comes from IRS publications, revenue procedures, or the statute. For the 1099 side in depth, see our 1099 physician taxes guide; for the law itself, what the One Big Beautiful Bill changed for physicians.

The 2025 law made the current seven rates permanent. Each rate applies only to taxable income above the threshold where it starts, so the number that matters for a deduction or deferral is your top, or marginal, rate.

A single attending with $300,000 of salary and the standard deduction has about $283,900 of taxable income, in the 35% bracket; a married attending with the same salary and a non-working spouse is in the 24% bracket. That difference changes which strategies are worth it, especially the traditional versus Roth choice: pre-tax contributions save more at 35% than at 24%. Two surtaxes sit on top of these rates: the 0.9% Additional Medicare Tax on wages above $200,000 (single) or $250,000 (joint), and the 3.8% net investment income tax covered below. To see what this means for a paycheck, try our take-home pay guide.

1. Max every pre-tax plan your employer offers

For 2026, you can defer $24,500 to a 401(k) or 403(b), plus $8,000 more at 50 and over or $11,250 more at ages 60 through 63 (Notice 2025-67). A 457(b) has its own separate $24,500 limit, so a physician offered both a 403(b) and a 457(b) can defer $49,000. If you are 50 or older and earned over $150,000 in FICA wages from that employer in 2025, your catch-up contributions have to go in as Roth. Our contribution limits guide covers how the limits stack and what to check before using a non-governmental 457(b).

2. Fund an HSA if you have a high-deductible plan

An HSA takes $4,400 for self-only coverage or $8,750 for family coverage in 2026, and $4,500 or $9,000 in 2027 (Rev. Proc. 2026-24). Contributions through payroll avoid income tax and FICA, growth is untaxed, and withdrawals for eligible medical expenses are tax-free. Invest it and pay current medical bills from cash if you can; see our HSA strategy guide.

3. Do a backdoor Roth IRA every year

Attendings are usually over the income limit for direct Roth IRA contributions, so they contribute $7,500 to a nondeductible traditional IRA and convert it. There is no deduction, but the growth is tax-free for life. The trap is the pro-rata rule: for Form 8606, traditional IRAs include SEP-IRAs and SIMPLE IRAs (Form 8606 instructions), so any pre-tax IRA balance on December 31 makes part of the conversion taxable. Roll old pre-tax IRA money into a workplace plan first if your plan accepts it. Step-by-step instructions are in our backdoor Roth guide, and the backdoor Roth calculator checks the pro-rata math.

4. Use a mega backdoor Roth if your plan allows it

Some 401(k) plans accept after-tax contributions above the $24,500 deferral limit, up to the $72,000 total for employee and employer contributions combined, and let you convert them to Roth. Whether you can do it depends entirely on your plan document. See our mega backdoor Roth guide.

The deduction for state and local income and property taxes, capped at $10,000 since 2018, is capped at $40,400 for 2026 ($20,200 if married filing separately). The cap shrinks by 30% of modified AGI above $505,000 ($252,500 married filing separately), but not below $10,000 (IRS). It rises 1% a year through 2029 and returns to $10,000 after that (P.L. 119-21, section 70120).

• MAGI up to $505,000: the full $40,400.
• MAGI of $550,000: $40,400 minus 30% of $45,000, or $26,900.
• MAGI of about $606,000 or more: back to $10,000.

A physician in a high-tax state who has taken the standard deduction for years should rerun the comparison. With $30,000 of state income tax and property tax, plus mortgage interest and giving, itemizing can now beat the $32,200 joint standard deduction by a wide margin. Because pre-tax retirement contributions lower MAGI, they can also keep you under the $505,000 threshold. Physicians who own a practice may be able to go further: IRS Notice 2020-75 lets partnerships and S corporations deduct state income taxes they pay at the entity level, outside the individual cap, where the state offers that election.

Three changes take effect in 2026 (Pub. 505 (2026); IRS):

• A 0.5% floor for itemizers. Only charitable contributions above 0.5% of your AGI are deductible. At $400,000 of AGI, the first $2,000 of giving doesn't count.
• A smaller benefit in the 37% bracket. Itemized deductions are reduced by 2/37 of the lesser of your itemized deductions or your taxable income above where the 37% bracket starts ($640,600 single, $768,700 joint). By our math, that makes each itemized dollar worth about 35 cents instead of 37.
• A deduction for non-itemizers. You can deduct up to $1,000 of cash gifts ($2,000 joint) without itemizing (IRS Topic 506). Gifts to donor-advised funds don't qualify.

Give appreciated stock instead of cash. For stock held more than a year, you can generally deduct its fair market value, up to 30% of AGI for gifts to public charities (Pub. 526), and because you never sell it, you never realize the gain. Bunch with a donor-advised fund if your giving is steady: putting two or three years of gifts into the fund in one year clears the 0.5% floor once and may push you over the standard deduction, while the fund pays out to charities over time.

7. Put side income in a solo 401(k) and pay as you go

Locums, moonlighting, consulting, and expert witness work let you open a solo 401(k) and contribute 20% of net self-employment earnings on top of your day job's plan. Cover the tax with estimated payments (Form 1040-ES) or by raising withholding at your W-2 job, which the IRS treats as paid evenly through the year (Form 2210 instructions). If your W-2 pay already passes the Social Security wage base, your 1099 income owes only Medicare tax on top of income tax, and an S corporation rarely helps. Our 1099 physician taxes guide works through two examples.

8. If you own a practice, look at QBI, entity taxes, and a cash balance plan

• QBI. Physician services are a specified service business (26 CFR 1.199A-5), so the 20% qualified business income deduction phases out between $201,750 and $276,750 of taxable income for single filers and $403,500 and $553,500 for joint filers in 2026 (Rev. Proc. 2025-32). Retirement contributions can pull you back into that range.
• Entity-level state tax. If your state has a pass-through entity tax election, paying state tax through the practice can sidestep the individual SALT cap (Notice 2020-75).
• Defined benefit or cash balance plans. These allow much larger deductible contributions than a 401(k) for older, high-earning owners. The maximum annual benefit one can pay is $290,000 in 2026 (Notice 2025-67); the contribution depends on age and actuarial assumptions, so get an actuary's quote. Our cash balance plan guide walks through the limits, a worked example, and the costs.

For entity choice and the S corporation math, see the S-corp tax savings calculator and talk to a CPA before filing an election.

9. Harvest losses, and watch the wash sale rule

Capital losses offset capital gains, and up to $3,000 a year ($1,500 married filing separately) of net loss offsets ordinary income, with the rest carried forward (IRS Topic 409). The loss is disallowed if you buy substantially identical securities within 30 days before or after the sale (Pub. 550), so swap into a similar fund rather than the same one.

10. Put investments in the right accounts

Most attendings pay the 3.8% net investment income tax, which applies to the lesser of net investment income or modified AGI above $200,000 single or $250,000 joint (IRS Topic 559). Those thresholds aren't indexed for inflation (IRS), so more physicians cross them every year. That raises the value of holding interest-paying investments in tax-deferred accounts and broad stock index funds, which mostly grow through unrealized gains, in taxable accounts. See our guide to investing your first $100,000.

11. Know which loan benefits are taxable

• Interest deduction: up to $2,500 a year, phasing out between $85,000 and $100,000 of modified AGI for single filers and $175,000 and $205,000 for joint filers in 2026 (Rev. Proc. 2025-32). Many residents qualify; most attendings don't.
• PSLF: forgiveness is not taxable (StudentAid.gov).
• IDR forgiveness: the federal exclusion that covered forgiveness in 2021 through 2025 has ended (Pub. 4681), and the 2025 law kept a permanent exclusion only for death and disability discharges (P.L. 119-21, section 70119). Forgiveness under IBR or RAP after 2025 is therefore generally taxable. If that is your plan, set money aside. Our IBR vs. RAP guide covers the plans.

12. Pay disability premiums after tax, and use the family accounts

• Disability insurance: benefits from a plan you paid for with after-tax dollars aren't taxable; benefits from an employer-paid plan, or one paid pre-tax through a cafeteria plan, are (Pub. 525). If your employer lets you choose, paying the premium yourself keeps the benefit whole when you need it.
• Dependent care FSA: the exclusion rose from $5,000 to $7,500 in 2026 (IRS), worth checking at open enrollment if you pay for child care.
• Trump accounts: for children born 2025 through 2028 the government contributes $1,000, total contributions are capped at $5,000 a year, and employers can contribute up to $2,500 a year tax-free to the employee (IRS). Ask whether your employer participates.

• Open enrollment (November): pick the HSA-eligible plan if it fits, set 2027 HSA and dependent care elections, and choose after-tax disability premiums if offered.
• Before your last paycheck: check that your 401(k)/403(b) and 457(b) deferrals will reach the amounts you want; deferrals come out of pay, so December is the last chance.
• By December 31: harvest losses, make charitable gifts (stock takes time to transfer), fund a donor-advised fund if you are bunching, and complete the backdoor Roth conversion for 2026 if you contributed.
• With 1099 income: raise W-2 withholding or plan the January 15, 2027 estimated payment.
• By April 15, 2027: 2026 IRA and HSA contributions are still allowed, and the 2026 return is due.

Physicians get pitched a steady stream of tax strategies. A few rules of thumb: be wary of anything sold as a way for W-2 employees to deduct ordinary living costs, any product whose main selling point is a tax break (such as cash-value life insurance bought for tax-free growth before your retirement accounts are full), and S corporation advice that doesn't ask about your W-2 wages. If a strategy depends on a specific Code section, ask the person selling it to show you the IRS guidance in writing, and have your own CPA review it.

The plain strategies above compound. A physician who defers $49,000 a year at a 35% bracket avoids about $17,150 of federal income tax this year, and the money grows tax-deferred for decades. That is worth more than almost any clever deduction.
