Iran’s tax system is based on the Direct Tax Act and the Value Added Tax (VAT) Law, among other regulations.
Tax obligations apply to both local and foreign investors, determined by income, property, and commercial activity.

The Iran National Tax Administration (INTA) oversees tax registration, audits, and filing procedures.
Cosmos Legal ensures that clients who establish businesses or conduct commercial activities in Iran are properly registered, their tax returns are accurately prepared, and administrative procedures are efficiently managed.

2. Types of Taxes in Iran

Rates for individuals range from 15% to 35%, while corporate tax is 25%.
Foreign companies earning Iranian-sourced income are subject to tax.
