Amend SB 645 by adding the following section to the bill,
appropriately numbered, and renumbering the existing sections of
the bill appropriately:
      SECTION ____.  Subchapter B, Chapter 403, Government Code, is
amended by adding Section 403.0141 to read as follows:
      Sec. 403.0141.  REPORT ON INCIDENCE OF TAX.  (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 $20,000,000, 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; and
            (3)  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.
