♦ Determination of whether the proposed tax rate is more than 8% over the effective tax
rate.

The 8% rule as set by state law imposes the maximum rate that may be adopted by
taxing authorities without being subject to tax rollback procedures. If a taxing authority
imposes a tax rate in excess of 8% of the effective tax rate, taxpayers may take
measures that could rollback the adopted rate to an 8% increase. Generally, these
procedures involve a petition of eligible voters and a rollback election.

Article XI, Section 5 of the State of Texas Constitution states in part:

"...but no tax for any purpose shall ever be lawful for any one year, which shall exceed
two and one-half percent of the taxable property of such city."

The State of Texas does not provide for a statutory debt limit for cities. The truth-in-taxation

The property tax rate to meet these needs cannot exceed $2.50 per $100 valuation.
