The "tax cap" laws can be changed only by the General Assembly and the Governor. The General Assembly has two chambers, the House and the Senate. You elect representatives to both chambers and you also elect the Governor.
Lobbyists representing the taxing districts constantly tell the Governor's office and the legislators that the tax caps are not working, and are causing undue hardship on the tax districts. Each year they manage to convince some legislators to introduce new bills in the General Assembly that would weaken the tax caps or eliminate them all together.
The legislators and the governor need to hear from you, the taxpayer. Please call or write your state legislator and the governor's office. Advise them that you believe the tax caps are working and should not be changed in any way. Remind them that if any tax district needs more than a 5% increase in spending, they are permitted to ask the voters for a tax increase, over and above the 5% limit, by means of a referendum. Changing the tax cap laws would allow tax districts to increase property taxes without any limits and without referendum.
