Iran Social Contributions Guide

Social Security Organization (SSO) — سازمان تأمین اجتماعی

• Employee share — 7% of gross salary: The employee contributes 7% of the gross monthly salary to the SSO. The employer deducts this amount at source and remits it together with the employer share to the Social Security Organization. The contribution is mandatory for all employees with a formal employment contract.
• Employer share — 20-23% of gross salary: The employer pays 20% of the gross salary as the standard SSO contribution plus an additional 3% for the unemployment insurance fund (the "صندوق بیمه بیکاری" — the "Unemployment Insurance Fund"), bringing the total employer burden to 23%. The standard 20% rate applies to the basic SSO coverage (the "بیمه تأمین اجتماعی" — the "social security insurance").
• Total combined rate — 27-30%: The combined employee (7%) and employer (20-23%) contributions result in a total social security burden of 27% to 30% of the gross salary. This is one of the highest social security contribution rates in the region.
• Contribution ceiling: The SSO applies a maximum contribution ceiling (the "سقف حق بیمه" — the "insurance ceiling") that is updated annually by the Supreme Labor Council. The ceiling is typically set at 7 to 10 times the national minimum wage. Any salary above the ceiling is exempt from further SSO contributions.

Self-Employed Contributions

• Optional SSO coverage — 12-18%: The self-employed individuals may voluntarily register with the SSO under the "self-employed insurance" scheme (the "بیمه خویشفرمایی" — the "self-employed insurance"). The contribution rate ranges from 12% to 18% of the declared income, depending on the selected coverage package (basic, enhanced, or full).
• Coverage options: The basic package (~12%) covers the pension and the death benefits only. The enhanced package (~14-16%) adds the sickness and the maternity benefits. The full package (~18%) provides the comprehensive coverage including the unemployment and the occupational hazard benefits.
• Minimum income basis: The self-employed must declare a minimum income of at least the national minimum wage for the contribution calculation. The declared income may be adjusted annually.
• Government subsidy: The self-employed in certain sectors (e.g., the agriculture, the handicrafts, the rural areas) may qualify for a government subsidy of up to 10-15% of the contribution amount.

Healthcare Insurance Surcharge

• Additional 1-3%: In addition to the SSO contributions, the employee and the employer must pay an additional healthcare insurance surcharge of 1% to 3% of the gross salary, depending on the specific health insurance scheme (the "بیمه درمان" — the "health insurance"). The surcharge is typically split between the employee (1%) and the employer (1-2%).
• Health insurance schemes: The main health insurance providers in Iran include the SSO health insurance (the "بیمه تأمین اجتماعی"), the Iranian Health Insurance Organization (the "سازمان بیمه سلامت ایران" — the "Health Insurance Organization") for the civil servants and the low-income groups, and the private health insurance companies for the supplementary coverage.
• Mandatory coverage: All employees must be covered by a basic health insurance scheme. The employer is responsible for arranging and paying for the health insurance coverage.

Foreign Workers

• No SSO coverage without work permit: The foreign workers who do not hold a valid Iranian work permit (the "مجوز کار" — the "work permit") are NOT eligible for the SSO coverage. The employer may not register a foreign employee without a valid work permit.
• Work permit requirement: The foreign workers with a valid work permit are treated the same as the Iranian employees for the SSO purposes — the employee contributes 7% and the employer contributes 20-23%.
• Bilateral social security agreements: Iran has limited bilateral social security agreements with other countries. The foreign workers from the treaty countries may be exempt from certain SSO contributions or may have their contribution periods recognised in the home country.

FAQs

Are SSO contributions tax-deductible?

The employer's SSO contributions are fully tax-deductible as a business expense. The employee's 7% contribution is deductible from the personal income tax base. The self-employed contributions are also tax-deductible up to the applicable ceiling.

What is the unemployment insurance rate?

The unemployment insurance contribution is 3% of the gross salary, paid entirely by the employer. The employee does NOT contribute to the unemployment insurance fund. The unemployment benefits are payable for up to 50 months depending on the age and the contribution history.

How often are SSO contributions remitted?

The employer must remit the SSO contributions (employee + employer shares) to the SSO on a monthly basis, typically by the end of the following month. Late remittance attracts penalties of 2% per month.
