New Physicians Paid as Contractors: Tax Requirements and First-Year Considerations
For new physicians, contractor pay often looks simple on the surface and more demanding underneath. The key early issue is not just what you are being paid. It is whether the tax setup, cash-flow plan, and California practice structure actually match how that income is being earned.
What new physician contractors should assume at the start: if you are truly being paid as an independent contractor, the IRS generally treats you as self-employed. That usually means no built-in withholding, separate responsibility for income tax and self-employment tax, quarterly estimated payments, and a stronger need for clean bookkeeping from the start. For California physicians, it also means the entity question should be handled carefully rather than with generic “just form an LLC” advice.
- No withholding. Contractor pay usually arrives without federal income tax, Social Security, Medicare, or California withholding already taken out.
- Quarterly tax responsibility. Federal and California estimated taxes usually become part of the job quickly once the income is steady.
- More setup matters. The earlier the bank-account, bookkeeping, expense-tracking, and entity questions are handled, the less expensive the cleanup usually is later.

1. What changes when a physician is paid as a contractor
The first point is the classification itself. The IRS says an independent contractor is self-employed, but it also says you are not an independent contractor if the employer has the legal right to control what will be done and how it will be done. That matters because some new physicians hear “1099” and assume the label settles everything. It does not.
If the contractor classification is correct, the main tax changes are immediate:
- compensation is usually reported on Form 1099-NEC instead of a W-2
- for 2026 the federal 1099-NEC reporting threshold rose to $2,000, up from $600, so smaller payments may not generate a form, though the income is taxable either way and records should be kept regardless of whether a form arrives
- the income is generally reported on Schedule C
- self-employment tax is usually calculated on Schedule SE
- estimated tax payments often replace paycheck withholding
The biggest surprise for many new physicians is self-employment tax. The IRS currently states that the self-employment tax rate is 15.3 percent, split between Social Security and Medicare. The 12.4 percent Social Security portion applies only to the first $184,500 of net self-employment income for 2026, while the 2.9 percent Medicare portion has no cap. An additional 0.9 percent Medicare tax applies above $200,000 for single filers and $250,000 for married filing jointly. For a physician earning attending-level income, the Social Security cap means the rate effectively steps down past that wage base, but the Medicare and additional Medicare pieces keep running. Accurate as of Tax Year 2026.
Another practical point: you do not need to wait for a 1099 form to know the income is taxable. The reporting form helps with matching and compliance, but the tax obligation follows the income itself.
2. What to set up in the first year
The right first-year setup is usually operational before it is strategic. New physicians often ask about an S corporation before they have a clean way to track income, expenses, and estimated taxes. That order is usually backwards.
The higher-value first moves are typically:
- provide a clean Form W-9 when the payer requests it
- decide whether to use your Social Security number or obtain an EIN where appropriate
- open a separate business bank account for contractor deposits and related expenses
- build a simple bookkeeping routine from month one
- reserve cash regularly for federal and California taxes instead of waiting for quarter-end surprises
- track ordinary and necessary business expenses with support, not memory
One first-year move does carry real strategic weight even before any entity decision: retirement savings. A self-employed physician can open a solo 401(k) with a 2026 total contribution cap of $72,000, made up of an employee deferral of $24,500 plus employer contributions before any age-based catch-up, or a SEP IRA with a 2026 cap of $72,000. These shelter income at exactly the point new contractor physicians often have their first high-earning, low-withholding year. Accurate as of Tax Year 2026.
The IRS says Form W-9 is used to provide your correct taxpayer identification number to the person required to file an information return. It also says you can get an EIN directly from the IRS in minutes for free. That does not mean every new physician must have an EIN immediately, but it often makes the contractor setup cleaner than sharing a Social Security number with multiple payers.
Bookkeeping matters earlier than many physicians expect. Contractor work often creates deductible expenses that an employee would not track the same way, but deductions only help if the records are clean. A separate account, a consistent expense trail, and a monthly review usually matter more in year one than chasing a long list of theoretical write-offs.
2026 California timing note. California does not use the federal four-equal-payments schedule. The state runs a 30/40/0/30 installment schedule, which means 30 percent is due in April, 40 percent in June, nothing in September, and the final 30 percent in January.
About 70 percent of the year’s California estimated tax is due by mid-June.
There is no September installment for California individuals, so the next California estimated-tax date after mid-2026 is January 15, 2027. September 15, 2026 is a federal date only. This front-loading catches most new physician contractors in year one, which is exactly why reserving cash early matters. Accurate as of Tax Year 2026.
The IRS says self-employed individuals generally file an annual return and pay estimated taxes quarterly, and California FTB says self-employed individuals may also be required to pay estimated taxes quarterly. Our article on estimated tax payments for individuals in 2026 covers the safe-harbor side and payment timing in more detail.
3. The QBI deduction trap most physician content skips
Here is the part that generic 1099 advice gets wrong for physicians: most attending physicians get little or no qualified business income deduction. Medicine is a specified service trade or business under the tax code, and the QBI deduction for these trades phases out as income rises. For 2026 the phaseout runs from $403,500 to $553,500 for married filing jointly, and from $201,750 to $276,750 for single filers and most other non-joint filers. Above the top of that range, the QBI deduction for a physician is generally zero.
This matters because a lot of online advice sells the S corporation or the LLC partly on the QBI deduction. For an attending earning above the phaseout, that benefit usually is not there. The idea is not wrong for every taxpayer, it is just frequently inapplicable to physicians at typical attending income. Accurate as of Tax Year 2026.
4. What California physicians should think through before rushing into an entity
This is where online advice gets loose. For California physicians, entity choice is not just a tax question.
The Medical Board of California states that for physician practice purposes it only accepts corporations formed in California that are professional medical corporations, and that limited liability and general corporations are not accepted. That does not mean every new physician paid as a contractor needs to incorporate immediately. It means entity advice has to fit physician rules, not generic freelancer rules.
In practice, the early questions are usually:
- is this temporary moonlighting income or the beginning of a larger independent practice path?
- is the income level high and stable enough to justify more entity administration?
- is there a real need for payroll, corporate compliance, and separate tax filings yet?
- is the physician practicing through a structure that is actually allowed for California medical work?
For some new physicians, the right year-one answer is to stay simple operationally, keep records clean, and revisit structure once the income pattern is clearer. For others, especially where contractor income becomes a major ongoing part of earnings, a medical corporation review may make sense sooner.
The mistake is assuming that “1099 income” automatically means “form an LLC” or “elect S corporation immediately.”
That is also why the tax and legal pieces should not be separated too casually. A structure can look tax-efficient in a vacuum and still be the wrong operating choice for a California physician.

Frequently asked questions
Does a physician paid on 1099 income have to pay self-employment tax?
Usually yes, if the physician is truly being paid as an independent contractor. The IRS says independent contractors are self-employed, and self-employed individuals generally must pay self-employment tax as well as income tax.
Do I need to wait for a 1099 before reporting the income?
No. Taxable contractor income still has to be reported even if a form arrives late, is incorrect, or is never issued.
Should a new physician contractor form an LLC in California?
Not as a default answer. California physicians need entity advice that fits medical-practice rules, and the Medical Board says it only accepts California professional medical corporations, not limited liability or general corporations, for physician practice purposes.
Do new physician contractors need quarterly estimated taxes?
Often yes. The IRS says self-employed individuals generally pay estimated taxes quarterly, and California FTB says self-employed individuals may also need quarterly estimated tax payments.
Is getting an EIN mandatory for a new physician contractor?
Not always, but it is often useful. The IRS says an EIN can be obtained directly from the IRS for free in minutes, and many contractors prefer using it instead of sharing a Social Security number with multiple payers.
Do most physicians get the QBI deduction on 1099 income?
Usually not at attending income levels. Medicine is a specified service trade or business, and the QBI deduction phases out from $403,500 to $553,500 for married filing jointly for 2026, and from $201,750 to $276,750 for single filers and most other non-joint filers. Above the top of that range the deduction is generally zero.
When are California estimated taxes due for a new physician contractor?
California uses a 30/40/0/30 schedule, not four equal payments. Thirty percent is due in April, 40 percent in June, nothing in September, and the final 30 percent in January. Roughly 70 percent of the year’s California estimated tax is due by mid-June, which surprises most first-year contractors.
