Exisà ÂtÃÂs () was a fiscal official in the last centuries of the Byzantine Empire.
Its functions were similar to those of the earlier epoptes, along with whom it is often mentioned in the 11th centuries: the exisà Âsis (á¼ÂþïÃÂÃÂÃÂùÃÂ, "equalization"), i.e. the fiscal survey and revision of the amount of tax owed by individuals. The distinction between the exisà ÂtÃÂs and the apographeus is likewise unclear, although the two functions are often documented as being held in tandem, and tax officials are recorded as carrying out both exisà Âsis and apographÃÂ.
