License fees can be divided into several categories that vary depending on the jurisdiction. Usually there is an initial set up cost, annual cost, monthly fees, and possibly a host of other expenses depending which kind of licenses and for which country it is applied to.
In addition to this the companies are often subject to increased rate, or a lump sum, of tax or fees should their revenue exceed certain thresholds. Some jurisdictions levy VAT, import duty, corporate taxes and other fees on top of this, while others opt for a simpler system which covers all expenses through a single tax bracket.
