5brackets, lowering the individual income tax top rate of taxation and creating

Analysis by the Legislative Reference Bureau
Under current law, there are 3 income tax brackets for single individuals,
certain fiduciaries, heads of households and married persons. The brackets for single
individuals, certain fiduciaries and heads of households are taxable income from $0
to $7,500; from more than $7,500 to $15,000; and more than $15,000. The brackets
for married persons filing jointly are taxable income from $0 to $10,000; from more
than $10,000 to $20,000; and more than $20,000. The brackets for married persons
filing separately are taxable income from $0 to $5,000; from more than $5,000 to
$10,000; and more than $10,000.
The rate of taxation under current law, for taxable years beginning before
January 1, 1998, for the lowest bracket for single individuals, certain fiduciaries,
heads of households and married persons is 4.9% of taxable income, the rate for the
middle bracket is 6.55% and the rate for the highest bracket is 6.93%.

For taxable years beginning after December 31, 1997, current law lowers the
rate of taxation for all brackets by 1.0%. Therefore, for taxable years beginning after
December 31, 1997, the rate of taxation under current law for the lowest bracket for
single individuals, certain fiduciaries, heads of households and married persons is
4.85% of taxable income, the rate for the middle bracket is 6.48% and the rate for the
highest bracket is 6.87%. For taxable years beginning after December 31, 1998,
current law also indexes for inflation the maximum dollar amount in each tax
bracket and the corresponding minimum dollar amount in the next bracket.
For taxable years beginning after December 31, 1998, this bill reduces the
number of individual income tax brackets to 2 and lowers the rate of taxation for the
highest bracket to 6.0%. Under the bill, the brackets and rates for single individuals,
certain fiduciaries and heads of households are taxable income from $0 to $15,000,
at a rate of 4.85%; and more than $15,000, at a rate of 6.0%. The brackets and rates
for married persons filing jointly are taxable income from $0 to $20,000, at a rate of
4.85%; and more than $20,000, at a rate of 6.0%. The brackets and rates for married
persons filing separately are taxable income from $0 to $10,000, at a rate of 4.85%;
and more than $10,000, at a rate of 6.0%.
This bill also delays the start of indexing for inflation the maximum dollar
amount in each tax bracket and the corresponding minimum dollar amount in the
next bracket until taxable years beginning after December 31, 1999.
The bill also creates a bipartisan revenue shortfall task force to develop and
recommend legislation that will make up the revenue shortfall to the state caused
by lowering the top individual income tax rate from 6.93% to 6.0%. The task force
shall submit that proposed legislation to the legislature before January 1, 1999.
For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.
