3-Step Tax Strategy for 1099 Physicians: Cut Your Tax Bill

In a Nutshell

If you’re a physician with any 1099 income, the tax code gives you options that pure W-2 earners just don’t have.
The three big moves are simple in concept: claim the deductions you already qualify for, set up the right business entity, then layer in advanced strategies once those basics are locked in.
A tax preparer files your return. A tax strategist plans before the year ends so you owe less in the first place. You probably want both.
Real numbers from a sample physician household showed a tax bill drop of around 58 percent after applying these moves. Your mileage will vary, but the framework holds.

There’s a quote from Judge Learned Hand that gets passed around in tax circles. He said something like, “anyone may arrange his affairs so that his taxes shall be as low as possible.” No moral obligation to overpay. No patriotic duty to leave money with the Treasury. That’s been the law of the land for almost a century.

And yet most high-earning doctors I’ve heard from feel like the tax code was written to punish them. Honestly, when you’re a pure W-2 employee, that’s kind of true. The biggest deductions, the depreciation tricks, the entity-level planning, those mostly go to business owners and investors. Not to people who get a paycheck twice a month with the taxes already withheld.

But the moment you pick up some 1099 income, whether from locums shifts, a side practice, expert witness work, telehealth contracts, even consulting for a medical device company, the rules change. You’re now running a business in the eyes of the IRS. And businesses get treated very differently.

That’s what this guide is about. Tax planning for physicians with 1099 income, written for people who don’t really want a master’s in tax law but do want to keep more of what they earn.

Tax Preparer vs. Tax Strategist: Why the Difference Matters

Most doctors I’ve talked to have a tax preparer. Maybe a CPA, maybe an enrolled agent, maybe the same person their parents used. That preparer does a fine job filing the return every April.

Here’s the thing though, a preparer mostly looks backward. They take what already happened and put it on the right forms. They don’t usually call you in October to suggest you buy a piece of equipment before year-end, or restructure your locums income into an S Corp, or set up a defined benefit plan that could shelter another hundred grand.

A tax strategist (or tax advisor for physicians, depending who you ask) looks forward. They sit down with your projected income, your business structure, your retirement goals, and basically reverse-engineer the lowest legal tax bill possible.

Quick comparison, the way I think about it:

A preparer is the mechanic who fixes your car after something breaks.
A strategist is the engineer who designs the car so it doesn’t break in the first place.

Both are useful. But if you’re earning $500K or more and your only tax help is a once-a-year preparer, you’re probably leaving real money on the table. Five figures, in many cases. Sometimes six.

Rough rule of thumb, a tax strategist starts paying for themselves once your federal bracket hits 35 percent. If you live in California, New York, or another high-tax state, the math gets even better.

The 3-Step Tax Planning Framework for Physicians

Tax planning sounds complicated, and parts of it are. But the framework itself is pretty simple. Three steps, in this order:

Claim every deduction you already qualify for.
Get the right entity structure underneath your income.
Add advanced strategies once steps one and two are working.

Most doctors I’ve seen skip straight to step three. They hear about cost segregation studies or oil and gas deductions at a conference and try to jam them into a structure that wasn’t built for it. The result is usually messy, occasionally audited, and almost always less effective than just doing the boring stuff first.

So let’s start with the boring stuff. The stuff that actually works.

Step 1: Maximize Deductions You May Already Qualify For

These are physician tax deductions that come from money you’re probably already spending. The goal is just to run that spending through your business properly so the IRS lets you write it off.

Home Office

If you have a home office and any 1099 income that flows through it, you can deduct a portion of your home expenses. Standard advice says to divide office square footage by total home square footage. That ratio is fine, but there’s a better way.

Subtract the shared common space (hallways, kitchen, dining room, living room) from your total home square footage first. Now your office is being measured against the actual private space in the home, not against the parts everyone shares. The ratio jumps. The deduction grows.

If you keep a business vehicle in your garage, add at least part of the garage square footage to your office number too.

Travel and Per Diem

Every city in the US has an IRS-published per diem rate. If you leave your house and don’t return for more than 12 hours, you can typically claim that per diem in place of tracking actual meal and incidental costs. For locums physicians working long shifts or traveling to other facilities, this stacks up fast.

Say you work 130 shifts a year that cross the 12-hour mark. At an average per diem of around $145 per day, that’s nearly $19,000 in deductions you’d otherwise miss.

Meal Expenses

Meals with a colleague or referral source, 50 percent deductible.
Food you provide for your staff, generally 100 percent deductible.
Tickets to sporting events, no longer deductible as entertainment. Sorry.

Hiring Your Kids (and Sometimes Parents)

This one always raises eyebrows, but it’s allowed. You can put your children on the payroll of a Schedule C business and pay them up to the standard deduction (around $15,750 for 2025) federal-tax-free. That’s about $47K of deductions if you have three kids old enough to do real work.

Quick caveats:

Pay them through a Schedule C or Schedule E, not your S Corp directly. Children under 18 working in a parent’s sole proprietorship are exempt from FICA and Medicare.
The work has to be real. Age-appropriate, documented, actually performed.
You can also put grandparents on payroll if you’re already supporting them. The deduction might still beat the FICA cost.

Depreciation and Bonus Depreciation

100 percent bonus depreciation is back. That means qualified business equipment, furniture, vehicles used more than 50 percent for business, and a long list of other purchases can be written off entirely in the first year.

Your home office desk. The exam table. Computers. Diagnostic tools. The pickup truck you use for site visits. All potentially deductible up front.

Vehicle Expenses

Two methods, you pick whichever is bigger each year:

Standard mileage rate (around 70 cents per mile for 2025).
Actual expenses (gas, insurance, maintenance, depreciation, interest) multiplied by your business-use percentage.

If your S Corp is domiciled at your home address, every trip from home to a work site counts as a business mile. Not commuting. That alone can push your business-use percentage past 50 percent, which unlocks bonus depreciation on the vehicle.

Health Insurance, HSAs, and a Few You Might Not Know

If you’re self-employed and pay your own health premiums, those are deductible above the line. You don’t need to itemize.

A Health Savings Account (HSA) is the obvious one. Less obvious is the 401(h) account, which can be tacked onto a defined benefit plan and lets you set aside funds for retirement medical expenses, often a lot more than an HSA allows.

Retirement Plans

For 1099 physicians, the options include:

Solo 401(k)
SEP IRA
SIMPLE IRA
Defined Benefit Plan (huge contribution limits, especially if you’re over 45)
Cash Balance Plan
Restricted Property Trust

You generally can’t contribute to a SEP IRA and a Solo 401(k) in the same year, but you can have both and use whichever fits the year. A defined benefit plan can shelter $100K to $300K annually depending on your age and income. That’s not a typo.

Step 2: Choose the Right Entity Structure

This is where the physician S Corp question comes in. The short answer: it depends on whether you already have W-2 income.

Here’s the catch most people miss. If you’ve already maxed out the Social Security wage base on your W-2 job (around $176K in 2025), and you then run your 1099 income through an S Corp, you’re forced to pay yourself a “reasonable salary.” That salary triggers a fresh round of FICA withholding. As the employer, you also pay half of FICA, and you don’t get that back.

In other words, the S Corp could actually cost you more in payroll tax than you’d save in self-employment tax. Sometimes the plain Schedule C is the better answer, at least until the 1099 side is large enough on its own.

Spouse with 1099 income who doesn’t have W-2 wages? Different story. S Corp probably saves them money.

Many high-earning doctors end up with both an S Corp and a C Corporation. The S Corp handles operating income. The C Corp acts as a management or admin entity, holding certain fringe benefits the S Corp can’t deduct, and capping income at the flat 21 percent federal corporate rate. If you’re already in the 37 percent bracket, shifting some income down to the C Corp can save real money, assuming you actually need the cash inside the business.

A quick visual that helps clients think about it:

Operating business (S Corp) on the left, generating income.
Wealth-holding entities on the right: retirement plans, real estate LLCs, holding companies, sometimes offshore trusts in places like Belize for asset protection.
A firewall in between, so a lawsuit against the practice doesn’t reach the family wealth.

That separation matters. Doctors get sued. The structure should assume it.

Step 3: Use Advanced Strategies When the Basics Are Already Covered

Once steps one and two are locked in, the bigger strategies start to make sense. These aren’t for everyone, and the wrong fit can do more harm than good. But for the right physician, they’re powerful.

Private Insurance Companies (831(b) Alternative)

You can set up a privately-owned insurance company that insures real risks your practice has (cyber, malpractice gap, business interruption, regulatory). Premiums are deductible. If no claims are filed, profits can flow to a Roth IRA holding the insurance company stock, which means tax-free growth.

Stay away from the older micro-captive structure unless you really know what you’re doing. The IRS has been aggressive there.

Charitable Impact Investments

These are structured deals where you invest in something like medical research, then donate it to a public charity. The deduction is based on appraised fair market value, often 4x to 6x what you put in. Used carefully, they’re legitimate. Used carelessly, they look like the kind of thing the IRS flags.

Cost Segregation Studies

Own your office building? Or a rental property? A cost segregation study breaks the building into shorter-life components (5, 7, 15 years instead of 39). Those shorter-life pieces qualify for bonus depreciation, which can mean a huge first-year write-off.

Working Interests in Oil and Gas

A working interest (not a royalty interest) in a developmental oil and gas well lets you write off intangible and tangible drilling costs in year one. Cash-on-cash returns often run in the 25 to 35 percent range. Stick with developmental wells from reputable operators, not wildcat exploration deals.

Case Study: How Tax Planning Can Change the Numbers

Take a hypothetical couple. Both physicians, mid-career, living in California.

Husband: $750K W-2, $400K 1099 income
Wife: $350K 1099 income
Three kids, ages 11, 13, 15
Total household income around $1.5M

Without planning, their federal tax bill comes out near $490K. California adds another $126K. Total: roughly $616K.

Now apply the framework:

Home office deduction: $12,000
Renting the home to the practice for 14 days a year (the Augusta rule): $14,000
Per diem on 130 shifts: $18,850
Three kids on payroll: $47,250
Athletic facility and medical reimbursement: $50,000
Defined benefit contribution: $100,000
Restricted Property Trust: $75,000
C Corp income shift: $50,000
Captive insurance premium: $100,000
Charitable impact investment: $200,000
Oil and gas working interest: $80,000
S Corp payroll tax deduction and California PTET election: $61,000

Total new deductions: about $750,000.

New federal tax bill: drops by roughly $350,000. The couple’s total tax burden falls by about 58 percent.

These aren’t gimmicks. Every line item exists in the tax code. The work is in fitting them together cleanly and documenting the business purpose behind each one.

What Physicians Should Review Before Year-End

If you do nothing else this quarter, sit down with whatever tax help you have and walk through these questions:

Am I getting any 1099 income, and is it flowing through the right entity?
Have I set up an accountable plan to reimburse home office, travel, and vehicle expenses from my business?
Am I funding the best retirement plan for my situation, or just defaulting to a SEP because it’s easy?
Have I documented payroll for any kids working in the business?
Is there a cost segregation study I should run on a property I own?
What deductions did I miss last year that I can build into this year’s plan?

Most of these decisions need to be made before December 31. After that, the options shrink fast.

If your current accountant has never brought one of these up without you asking, that’s worth thinking about. A real physician tax planning relationship is proactive, not just a once-a-year filing.

Want to know what this could look like for your specific situation? The honest first step is a conversation. Bring last year’s return, a rough picture of this year’s income, and a willingness to ask uncomfortable questions about what you’ve been doing. That’s usually enough to find five-figure savings on the first call.

FAQ

Can physicians deduct home office expenses?

Yes, if you have a legitimate space used regularly and exclusively for business, and you have 1099 or self-employment income. A pure W-2 physician generally cannot deduct a home office under current rules. The deduction covers a percentage of rent or mortgage interest, utilities, insurance, and depreciation.

Should a 1099 physician form an S Corp?

It depends on your other income. If you’ve already hit the Social Security wage base from a W-2 job, the S Corp may actually increase your payroll taxes. If 1099 is your main income source, an S Corp often saves money by reducing self-employment tax. Run the numbers both ways before deciding.

Can doctors deduct travel between home and work sites?

Commuting between home and a regular workplace isn’t deductible. But if your S Corp is domiciled at your home address, or you have a qualifying home office, travel from home to work sites can count as business mileage. For locums physicians traveling to multiple facilities, this gets more favorable.

Can physicians hire their children in their business?

Yes. The work must be real, age-appropriate, and documented. Pay them through a Schedule C or Schedule E (not directly from an S Corp), and children under 18 are exempt from FICA and Medicare. Each child can earn up to the standard deduction federal-tax-free, around $15,750 in 2025.

What is an accountable plan for physicians?

An accountable plan is a written agreement that allows your business (often your S Corp) to reimburse you for business expenses you paid personally, like mileage, home office, cell phone, and travel. Without one, reimbursements can be treated as taxable wages instead of deductions.

Are S Corp health insurance premiums deductible?

Yes. The S Corp pays the premiums and reports them on the owner’s W-2 as wages, but the owner then deducts them above the line on the personal return. Net result is the same as a deduction, with a little paperwork in the middle.

What retirement plans work best for 1099 physicians?

For high earners, a Solo 401(k) is usually the starting point. Adding a defined benefit plan or cash balance plan on top can push annual contributions well past $200K, especially for physicians in their 40s and 50s. SEP IRAs are simpler but generally allow smaller contributions than a Solo 401(k) at the same income level.
