California Tax Impact on Plasma Income
California has the highest state income tax in the nation, which affects your plasma earnings:
California state income tax ranges from 1% to 13.3%. Most plasma donors fall in the 2-6% bracket for their plasma income, meaning you'll keep less than donors in no-tax states like Texas or Florida.

| Annual Plasma Income | Federal Tax (~15%) | CA State Tax (~4%) | Take-Home |
|---|---|---|---|
| $6,000 | $900 | $240 | $4,860 |
