CLASSES OF NONEXCHANGE TRANSACTIONS
As if using a fancy term like “nonexchange” transactions was not enough to make accounting for these transactions sound complicated, the GASB went a little further by defining four different types of nonexchange transactions. Let us look at each of them.
Derived Tax Revenues
These are tax revenues that result from the government taxing an exchange transaction. There are at least three important types of taxes that would fall into this category.
1. Sales taxes
2. Personal income taxes
3. Corporate income taxes
Using sales tax as an example, a sale between, say, a retail store and its customer is the exchange transaction that “derives” the amount of the tax that the government is entitled to receive.
