Bill Summary · AB 829

Legislative bill overview

AB 829 establishes the Richard Paul Hemann Parkinson's Disease Program, creating a voluntary tax contribution fund through California's state income tax system that allows taxpayers to donate funds specifically for Parkinson's disease research. The bill was signed into law in August 2025 with unanimous support in both legislative chambers.

Why is this important

This mechanism provides an alternative funding stream for Parkinson's research without requiring taxpayer dollars or general fund appropriations. It leverages California's tax system to support disease-specific research while giving individuals direct control over whether and how much to contribute to this cause.

Potential points of contention

  • Administrative overhead: Voluntary tax contribution programs can have significant administrative costs relative to funds collected, potentially reducing the percentage of donations reaching research
  • Precedent concerns: Establishing disease-specific tax funds may invite similar requests from advocates of other diseases, fragmenting research funding across numerous small programs
  • Inequitable funding model: Reliance on voluntary contributions may result in unequal funding compared to conditions with larger, more affluent patient advocacy bases
