SB6303 – Providing several fifteen year tax incentives to encourage energy storage system and component parts manufacturing in Washington.
Prime Sponsor – Senator Nguyen (D; 34th District; White Center)
Current status – Scheduled for executive session in the Senate Committee on Environment, Energy & Technology at 8:00 AM on Friday January 26th. (The bill hasn’t ever had a hearing, as far as I can see; the sponsor is the committee chair, which may have something to do with that.). Passed out of committee the same day, and referred to Ways & Means.
Next step would be – Scheduling a hearing.

Summary –
The bill would set the B&O tax on businesses selling, manufacturing, or processing energy storage system and component parts in the state at 0.275% through 2040. (This would include batteries, thermal storage systems, mechanical systems including pumped hydro, and electrical systems like super capacitors and superconducting magnetic energy storage.)

It would also provide an annual credit of $4,000 for each person employed in a permanent full-time position manufacturing any of these, and an additional $4,000 credit for each position that lasts over ten years.

It would make the construction of facilities to produce these eligible for the sales tax deferrals on materials and equipment, labor, or services currently available for a variety of green investment projects. (These allow you to postpone starting to pay the taxes until two years after the completion of a project, and to pay them gradually over ten years.)

However, the bill specifies that the Legislature doesn’t intend to change the expiration of the preference based on the findings of the review…
