K-1 & Partnership Taxes>Kaiser Permanente

Quick answer

Kaiser Permanente physicians are employed by regional Permanente Medical Groups with different structures. Southern California Permanente Medical Group is a partnership: partners receive K-1s, pay self-employment tax, and make quarterly estimates. The Permanente Medical Group in Northern California is a professional corporation: shareholder physicians remain W-2 employees. Your region and cohort documents govern.

"Do Kaiser doctors get a K-1?" is a trick question, because there is no single Kaiser employer. Physicians work for regional Permanente Medical Groups, separate entities that chose different legal structures decades ago, and the structure your region uses determines your entire tax setup.

One caveat governs this whole page: structures vary by region, specialty, and cohort, and they change over time. Your offer documents and partnership or shareholder agreement govern, not any website, including this one. This guide is educational, and it tells you which questions to ask.

Which Permanente Group Are You In?

The region decides the structure. The structure decides the taxes.

The two largest groups illustrate the split. Southern California Permanente Medical Group (SCPMG) is organized as a partnership: published partnership materials describe physicians advancing to partner status after roughly three years, with monthly pay operating as an advance against the group's net earnings and a year-end reconciliation among partners. That is partnership taxation, and partners receive K-1s.

The Permanente Medical Group (TPMG) in Northern California took the other road: it is a professional corporation, and its senior physicians become shareholders while remaining employees on W-2 wages. Shareholder status there brings governance rights and compensation changes, but not partnership taxation. Other regions (Colorado, Georgia, the Mid-Atlantic states, the Northwest, Hawaii, Washington) each have their own group and their own answer.

The one-question test
Ask a current partner or shareholder in your group what tax forms they received last year. A K-1 from the group means partnership taxation and everything in our partnership hub applies. A W-2 only means you are in a corporate-model group and your planning stays on the employee side. The five structures groups use are mapped in our ownership models guide.

The Partner Tax Life at a Partnership-Model Group

What flips when the K-1 replaces the W-2.

For physicians in a partnership-model group, partner conversion rewires four systems at once. Income tax withholding stops, replaced by quarterly estimates covering federal and state tax. Self-employment tax replaces payroll tax on your earnings, with the 2026 math here. Benefits move to self-employed treatment. And because advances are reconciled against the group's actual earnings, your taxable share and your bank deposits are two different numbers by design.

Watch Out

California adds its own layer

A California partner pays California tax on partnership income through estimates as well, and state estimate percentages are front-loaded differently than federal ones. The transition-year projection should cover both governments, not just the IRS.

Your First-Partner-Year Checklist

Five items, in order, before the first advance arrives.

  1. Confirm in writing which entity pays you and what forms you will receive in year one
  2. Open a tax set-aside account and route a fixed percentage of every advance into it
  3. Set federal and state estimates against the prior-year safe harbor
  4. Re-elect benefits knowing the self-employed rules, especially health coverage
  5. Get the retirement plan documents for partner status and model the new stack
Taxstra CPA Tip
The reconciliation feature of advance-based partnerships means a strong group year can add income on your K-1 beyond what you were advanced. Partners who set aside a percentage of every advance, rather than budgeting from last year's tax bill, absorb good years without an April scramble.
