When must a municipal budget be amended and what is the procedure for doing so?
A municipality must amend its budget to change amounts of appropriations stated in the budget or the purpose for which the money will be used. A two thirds vote of the entire membership of the governing body is required to amend a budget, and the municipality must either publish a Class 1 notice of the amendment within 15 days after amending the budget or post a notice of the changes on the municipality’s website within 15 days after any change is made.
