Physician Compensation Models: RVU-Based, Salary Plus Bonus, and Eat-What-You-Kill Tax Treatment

The same physician doing the same clinical work can end up with a very different tax result depending on how the compensation is structured. A W-2 employed physician on straight salary has payroll tax withheld and no self-employment tax exposure at all. A partner in an “eat what you kill” group taking home their own collections minus their share of overhead usually reports that income as a distributive share on a K-1, subject to self-employment tax in full. A locum tenens physician working the exact same shifts as a 1099 independent contractor faces a different set of deduction rules and a quarterly estimated-payment obligation neither of the other two has to think about. The compensation model isn’t just a pay structure question, it’s a tax structure question, and physicians frequently don’t realize how much it changes their actual take-home until the return is filed.

How is straight W-2 salary or salary-plus-bonus taxed?

A physician employed by a hospital system, a large group, or a corporate practice on a W-2 basis has the simplest tax picture of any compensation model, because the employer handles withholding and matching.

• Federal income tax, Social Security, and Medicare tax are withheld from each paycheck per IRC 3402 and IRC 3101. The employer pays a matching share of Social Security and Medicare tax and files the employment tax returns; the physician has no separate self-employment tax filing obligation on this income.
• A productivity bonus (a quarterly or annual bonus tied to RVU production, collections, or quality metrics) added on top of a base salary is still W-2 wages once paid, subject to the same withholding, even though the amount fluctuates with performance rather than being fixed like the base.
• A pure RVU-based employment model, where there’s effectively no fixed base and total compensation is calculated as a rate times the physician’s total work RVUs (wRVUs) for the period, is still W-2 wages if the physician is a common-law employee of the practice or hospital, regardless of how variable the pay is period to period. The variability of the pay doesn’t change the employment classification; what matters is the underlying employment relationship (who controls the work, provides the equipment and staff, sets the schedule), the classic common-law factors under Rev. Rul. 87-41.
• Because W-2 physicians have Medicare tax withheld on all wages with no cap, and Social Security tax withheld only up to the annual wage base, a high-earning W-2 physician still pays into Medicare on every dollar and, above the Additional Medicare Tax threshold ($200,000 single, $250,000 married filing jointly, not indexed for inflation), an extra 0.9% under IRC 3101(b)(2), just as any high-earning employee would.

How is a guaranteed payment taxed vs a distributive share?

In a physician group organized as a partnership or a multi-member LLC taxed as a partnership (as opposed to the S-corp structure covered in our entity structure guide), two different categories of partner compensation show up on the K-1, and both are treated less favorably than an S-corp wage-and-distribution split for SE tax purposes.

• A guaranteed payment under IRC 707(c) is a payment to a partner for services (or for the use of capital) determined without regard to the partnership’s overall income, functioning like a salary but paid to a partner rather than an employee. A guaranteed payment is deductible to the partnership (reducing the income allocated to all partners) and is ordinary income to the receiving partner, generally subject to self-employment tax in full.
• A distributive share of partnership ordinary business income (the partner’s percentage share of whatever the practice earns after guaranteed payments and expenses) also generally counts as net earnings from self-employment for a general partner or an LLC member who materially participates in the practice, under IRC 1402(a). There’s an exception for limited partners who don’t participate in management, but a working physician-partner in a medical practice almost never qualifies for that exception; the physician is actively practicing, not a passive investor.
• Unlike the S-corp structure, there’s no way to carve out a portion of partnership income as a non-SE-taxed “distribution,” because partnership distributions of already-taxed income (cash actually paid out to a partner from their capital account) are a return of previously-taxed profit, not a separate, lower-taxed category the way an S-corp shareholder distribution is. The full distributive share was already subject to SE tax when earned, regardless of when or whether it’s later distributed as cash.
• This is precisely why many multi-physician partnerships convert to a PC electing S-corp status once the SE tax savings from the wage-and-distribution split outweigh the added payroll administration; the partnership structure has no equivalent mechanism.

How is locum tenens or 1099 income taxed differently?

A physician working as a 1099 independent contractor, whether full-time locum tenens work, weekend moonlighting alongside a W-2 job, or telehealth contract work, reports that income on Schedule C and carries the full self-employment tax burden with none of the employer-side withholding or matching that a W-2 physician has.

• Net Schedule C income (gross 1099 payments minus deductible business expenses, covered in detail in our locum tenens tax guide) is subject to self-employment tax under IRC 1401 at the same 15.3%/2.9%-plus-Additional-Medicare-Tax rates that apply to a sole proprietor or an unincorporated partner.
• Because there’s no employer withholding at all on 1099 income, the physician must make quarterly estimated tax payments under IRC 6654 covering both income tax and self-employment tax, or face an underpayment penalty. This catches physicians who are used to W-2 withholding covering everything automatically and don’t realize 1099 income requires active quarterly payment management.
• A 1099 physician can deduct half of the self-employment tax as an above-the-line adjustment under IRC 164(f), and can generally establish a solo 401(k) or SEP-IRA against the net self-employment income, since 1099 income is earned income for retirement-plan purposes the same way W-2 wages or partnership self-employment income is.
• A physician who both works a W-2 job and picks up 1099 locum shifts on the side has two separate income streams with different withholding and deduction rules, and needs to run a combined estimated-payment projection across both, since W-2 withholding alone usually won’t cover the tax on the 1099 side.

How does the S-corp structure compare and when does it help?

The S-corp wage-and-distribution split, discussed at length in our entity structure guide, is the one model among W-2 employment, partnership, and sole-proprietor/1099 status that offers a mechanism to reduce total payroll or self-employment tax on the same underlying income, and it’s worth restating why in this compensation-model context specifically.

• A W-2 employed physician has no control over this at all; the employer sets the wage, and payroll tax applies to all of it regardless of structure, because the physician isn’t the business owner.
• A partnership-taxed physician-partner has no mechanism to split income into a lower-taxed distribution category; the entire distributive share and any guaranteed payment are SE-taxed.
• Only a physician-owner of a PC or PLLC that has elected S-corp status can set a reasonable-compensation wage below total practice profit and take the remainder as a distribution free of payroll and self-employment tax, which is the single largest controllable tax lever most solo and small-group practice owners have.
• This is also why a physician evaluating a job offer or partnership buy-in should look past the headline compensation number and ask how the entity is structured; identical gross compensation under a W-2 arrangement, a partnership guaranteed payment, and an S-corp wage-and-distribution split can produce meaningfully different after-tax take-home for the same dollar figure.

What should a physician check in their compensation model?

Confirm which category the compensation actually falls into, W-2 wage, guaranteed payment, partnership distributive share, S-corp wage-plus-distribution, or 1099 independent contractor income, since the label on the paycheck or 1099 doesn’t always match the substance, and the substance is what drives the tax result. If the income comes through a K-1 or a 1099, set up quarterly estimated payments before the first quarter’s deadline rather than after an underpayment penalty shows up at filing. And if there’s any real choice in how the practice is structured (a new partnership buy-in, a job offer with multiple compensation-model options), run the after-tax comparison before signing, not after the first year’s return comes back with a number that doesn’t match expectations.
