The formula used to calculate the amount collected by taxes is derived from understanding the relationship between appropriations, revenues, and taxes. Specifically, appropriations refer to the total planned expenditures or the budget a municipality needs to fund its services and responsibilities, while revenues represent the money that comes into the municipal budget from various sources, including grants, service fees, and, importantly, tax collections.

When you subtract the revenue from the appropriations, you are effectively determining the shortfall that needs to be covered by taxes. This calculation reveals how much in taxes must be collected to meet the total appropriations. Therefore, when the revenue is less than the appropriations, the difference—that is, the amount necessary to be raised through taxes—can be calculated, which is why this formula is used to find the amount of taxes that must be raised.

Understanding this financial relationship is essential for public works managers and those involved in municipal budgetary processes because it provides a clear framework for planning and funding public services effectively.
