šŸ‡®šŸ‡· Iran ā€” Provincial & Municipal Taxes

Iran's 31 provinces and municipalities have limited independent taxing powers. Municipal contributions (Ų¹ŁˆŲ§Ų±Ų¶ Ų“Ł‡Ų±ŲÆŲ§Ų±ŪŒ) are levied on construction, business licences, and various services. The Iranian National Tax Administration (INTA) administers national taxes. Significant portions of the economy operate in the informal sector or through foundations (bonyads) that have historically avoided taxation. Sanctions have severely distorted the economy and tax base. The value-added tax has been progressively expanded since 2008.
