5relating to: nonrefundable individual and corporate income and franchise tax
6credits for purchasing a thermal biomass heating system and fuel for such a
7system, property tax exemptions for thermal biomass heating systems and
8facilities used to store fuel for such systems, and a sales and use tax exemption
9for purchasing a thermal biomass heating system.
Analysis by the Legislative Reference Bureau
This bill creates a nonrefundable individual income tax credit, and a corporate
income and franchise tax credit, for the purchase of a thermal biomass heating
system (system) and a similar nonrefundable credit for the purchase of biomass fuel
for such a system. Under the bill, a claimant may claim 100 percent of the cost the
claimant spends for the purchase and installation of a system in the claimant's
primary residence or place of business. A claimant may also claim a credit for 100
percent of the cost of fuel for a system that is installed in the claimant's primary
residence or place of business.

To be eligible for the credit, the system must comply with all state requirements
related to emissions of air contaminants, and the provisions of the federal Clean Air
Act, that apply to the system on the day it is purchased. The credit related to
purchasing a system, or fuel for the system, for an individual's primary residence
may not be claimed by a nonresident or part-year resident of the state. Because the
credit is nonrefundable, it may be claimed only up to the amount of a taxpayer's
income or franchise tax liability.
Under the bill, a system is defined as a stove, furnace, or boiler that generates
heat from biomass and provides an energy efficiency conversion of at least 75
percent. Subject to a number of exceptions, such as an exception for garbage and for
certain nonvegetation-based waste, biomass is defined under the bill as a resource
that derives energy from wood or plant material or residue, biological waste, crops
grown for use as such a resource, or landfill gases.
The bill also creates real and personal property tax exemptions for a system and
for facilities that are used to store fuel for such a system. Finally, the bill creates a
sales and use tax exemption for the purchase of a system, including accessories,
attachments, and repair parts.
Because this bill relates to an exemption from state or local taxes, it may be
referred to the Joint Survey Committee on Tax Exemptions for a report to be printed
as an appendix to the bill.
For further information see the state and local fiscal estimate, which will be
printed as an appendix to this bill.
The people of the state of Wisconsin, represented in senate and assembly, do
enact as follows:
