(a) Before each regular session of the legislature, the comptroller shall report to the legislature and the governor on the overall incidence of the school district property tax and any state tax generating more than 2.5 percent of state tax revenue in the prior fiscal year. The analysis shall report on the distribution of the tax burden for the taxes included in the report.
(b) At the request of the chair of a committee of the senate or house of representatives to which has been referred a bill or resolution to change the tax system that would increase, decrease, or redistribute tax by more than $20 million, the Legislative Budget Board with the assistance, as requested, of the comptroller shall prepare an incidence impact analysis of the bill or resolution. The analysis shall report on the incidence effects that would result if the bill or resolution were enacted.

(c) To the extent data is available, the incidence impact analysis under Subsections (a) and (b):
(1) shall evaluate the tax burden:
(A) on the overall income distribution, using a systemwide incidence measure or other appropriate measures of equality and inequality; and
(B) on income classes, including, at a minimum, quintiles of the income distribution, on renters and homeowners, on industry or business classes, as appropriate, and on various types of business organizations;
(2) may evaluate the tax burden:
(A) by other appropriate taxpayer characteristics, such as whether the taxpayer is a farmer, rancher, retired elderly, or resident or nonresident of the state; and
(B) by distribution of impact on consumers, labor, capital, and out-of-state persons and entities;
(3) shall evaluate the effect of each tax on total income by income group; and
(4) shall:
(A) use the broadest measure of economic income for which reliable data is available; and
(B) include a statement of the incidence assumptions that were used in making the analysis.
