AB-921: Generator Air Pollution Rules and Tax Changes

This law temporarily exempts backup generators from air pollution rules during power-loss emergencies and provides income tax credits or sales tax breaks for buying certain backup generators.

What This Bill Does

  • Exempts the sale and purchase of portable or emergency backup generators from state air pollution regulations when a Governor-proclaimed state of emergency causes loss of electrical service to any part of the state.
  • Allows natural persons (individuals) and small businesses to claim an income tax credit for buying backup generators costing up to $7,000 for use in residences or commercial property during taxable years from 2026 through 2030.
  • Limits the total income tax credit allowed to $3,500 per taxable year.
  • Provides a state sales and use tax exemption on qualified backup electricity generators purchased only during the month of May between January 1, 2027, and December 31, 2031.
  • Restricts the sales tax exemption to generators costing $7,000 or less that are bought for noncommercial purposes.
  • Includes specific goals, performance indicators, and data collection details required by law for new tax expenditures.

Who It Names or Affects

  • Individuals (natural persons) who buy backup generators for their homes.
  • Small businesses purchasing backup generators for commercial property use.
  • Retailers selling qualified backup electricity generators during the month of May in eligible years or during declared emergencies involving power loss.
  • The State Air Resources Board, which administers air pollution regulations.

Terms To Know

Income Tax Credit
An amount subtracted directly from the income taxes a person or business owes to the state.
Sales and Use Tax Exemption

Limits and Unknowns

  • The income tax credit applies only if the generator costs $7,000 or less and is capped at a total of $3,500 per year.
  • The state sales tax exemption does not remove local city, county, or district taxes on these generators.
