Mission

NORTHWEST KIDNEY CENTERS' (NKC) MISSION IS TO PROMOTE THE OPTIMAL HEALTH, QUALITY OF LIFE AND INDEPENDENCE OF PEOPLE WITH KIDNEY DISEASE THROUGH PATIENT CARE, EDUCATION AND RESEARCH. NORTHWEST KIDNEY CENTERS IS A NOT-FOR-PROFIT, LOCALLY MANAGED PROVIDER OF KIDNEY DIALYSIS, PUBLIC HEALTH EDUCATION AND RESEARCH INTO THE CAUSES AND TREATMENTS OF CHRONIC KIDNEY DISEASE. FOUNDED IN SEATTLE IN 1962, IT WAS THE WORLD'S FIRST DIALYSIS ORGANIZATION. AMONG THE EIGHTH LARGEST DIALYSIS PROVIDERS IN THE COUNTRY, IT IS AN INFLUENTIAL MODEL BECAUSE OF ITS HIGH-QUALITY SERVICES, DEEP COMMUNITY CONNECTIONS AND GENEROUS DONOR SUPPORT.

Activities or mission (Part I)

TO PROMOTE THE OPTIMAL HEALTH, QUALITY OF LIFE AND INDEPENDENCE OF PEOPLE WITH KIDNEY DISEASE THROUGH PATIENT CARE, EDUCATION, AND RESEARCH.

THE ORGANIZATION PROVIDED PATIENT CARE IN TWENTY (20) FREE-STANDING CLINICS AND IN EIGHT (8) LOCAL HOSPITALS AND SUPERVISED SELF DIALYSIS TREATMENTS IN THE HOMES OF PATIENTS THROUGHOUT THE COMMUNITY. NKC SPENT OVER $25.8 MILLION MORE ON THE CARE OF PATIENTS WITH MEDICARE AND MEDICAID INSURANCE THAN THE PROGRAMS REIMBURSED US FOR. IN ADDITION, NKC PROVIDED MORE THAN $4.4 MILLION IN CHARITY CARE. NORTHWEST KIDNEY CENTERS' RENAL SPECIALTY PHARMACY, A RARITY IN THE NATION, SERVED MORE THAN 2,174 DIALYSIS PATIENTS AND KIDNEY TRANSPLANT RECIPIENTS DURING THE YEAR.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
