‘Increase’ excludes extending taxes currently set to expire.

The term “new annual revenues” means the net increase in annual revenues produced by the total of all tax or fee increases enacted by the general assembly in a fiscal year, less applicable refunds and less all contemporaneously occurring tax or fee reductions in that same fiscal year, and shall not include interest earnings on the proceeds of the tax or fee increase. For purposes of this calculation, “enacted by the general assembly” shall include any and all bills that are truly agreed to and finally passed within that fiscal year, except bills vetoed by the governor and not overridden by the general assembly. Each individual tax or fee increase shall be measured by the estimated new annual revenues collected during the first fiscal year that it is fully effective. The term “increase taxes or fees” means any law or laws passed by the general assembly after May 2, 1996, that increase the rate of an existing tax or fee, impose a new tax or fee, or broaden the scope of a tax or fee to include additional class of property, activity, or income, but shall not include the extension of an existing tax or fee which was set to expire.
