Filing & Compliance

• Monthly payroll lists and social security contributions due by the end of the month following the payroll month.
• Withheld income tax generally remitted to INTA monthly, often by the end of the month following the payroll month.
• Annual payroll tax return to INTA summarizing total salaries, taxes withheld, and social security contributions for the Iranian tax year (March 21 - March 20).

In Iran, employees' salaries are subject to income tax, deducted directly from their payroll by their employers. This tax is calculated based on a tiered system with varying rates and exemptions.

Income Tax

Iran's income tax system operates on a progressive scale. A tax-exempt threshold is determined annually. For the fiscal year ending March 20, 2026, annual income up to IRR 1,200,000,000 is exempt. Taxable income from IRR 1,200,000,001 to IRR 1,680,000,000 is taxed at 10%, from IRR 1,680,000,001 to IRR 2,760,000,000 at 15%, from IRR 2,760,000,001 to IRR 4,080,000,000 at 20%, and income exceeding IRR 4,080,000,001 is taxed at 30%. Both Iranian residents and foreign nationals working in Iran are subject to this tax on their Iranian-sourced income. Iranian residents are taxed on their global income.

Deductions and Exemptions

Several deductions and exemptions can reduce the taxable income:

• Social Security Contributions: The 7% employee share of social security contributions is typically deductible.
• Housing Loan Payments: Payments made towards housing loans can be deducted.
• Employer-Covered Medical Expenses: Medical expenses covered by the employer are exempt from taxation.
• Other Exemptions: Pensions, retirement allowances, termination payments, and service-related travel expenses and allowances are also exempt.

Social Security

Employers are generally required to make social security contributions for their employees. The total contribution is 30% of the employee's gross salary, with 23% paid by the employer and 7% by the employee. An additional 3% is paid by the employer for unemployment insurance. The coverage includes accidents, sickness, pregnancy, wage compensation, disability, retirement, and death. There are provisions for exemption, but often a compulsory accident insurance is required instead.

Payroll Procedures and Deadlines

Iran uses a Pay-As-You-Earn (PAYE) system where employers deduct tax directly from employee salaries. Employers must file monthly payroll lists with the Tax Office, following the Iranian calendar months for tax payments and filings.

Other Taxes and Considerations

Besides income tax and social security contributions, there might be other taxes or considerations applicable depending on the specific situation, such as property taxes or taxes on other sources of income. Always consult with a tax advisor for personalized guidance based on the most current regulations and your individual circumstances.
