Rental Income from Iran: Tax Obligations for Expatriates

🔑 Key Takeaway: Expats Are Taxed Like Locals, But Must Track Deadlines

Taxable Base: Only 75% of your gross rental income is taxable; 25% is statutorily deducted for depreciation and expenses under Articles 53 and 54.
2
Equal Treatment: Foreign nationals and expats are taxed exactly like Iranian citizens on income generated within Iran under Article 81.
3
Annual Exemption: If rental income is your only source of income in Iran, you may benefit from the annual individual exemption threshold under Articles 57 and 84.
4
Filing Deadline: The annual rental income tax return must be submitted electronically by the end of Tir (approx. July 22) for the previous Iranian calendar year.
5
Currency & Payment: Tax calculations and payments must be made in Iranian Rials (IRR), regardless of whether the rent is paid in foreign currency or transferred abroad.

Legal Framework and Relevant Articles

The taxation of rental income for expatriates is governed by the Iran Direct Taxes Act (IDTA). No single article explains the full cross-border tax process. The statutory deductions, progressive rates, equal treatment of foreigners, and filing deadlines come from different interconnected provisions.

Legal Source	Rule	Expat Impact
Articles 53 & 54, IDTA	Gross rent minus 25% for statutory expenses and depreciation equals taxable rental income.	Calculate base correctly Never pay tax on 100% of your gross rent.
Article 81, IDTA	Foreign nationals are subject to the exact same tax provisions, rates, and exemptions as Iranian nationals for income sourced in Iran.	No special expat rates You follow the same local tax brackets.
Articles 57 & 84, IDTA	Natural persons with no other income besides rent may apply the annual Article 84 exemption threshold to their taxable rental income.	Check eligibility Reduces taxable base if rent is your sole Iranian income.
Article 131, IDTA	Progressive tax rates for individuals (typically 15%, 20%, and 25% applied to taxable income brackets).	Apply brackets Higher rental yields push you into higher tax brackets.
Article 100 / 81, IDTA	The deadline to file the annual tax return is the end of the month of Tir (July 22) of the following year.	File on time Missing this triggers heavy non-forgivable penalties.

Scope of This Guide

This guide assumes an individual expatriate or foreign national owning residential or commercial real estate in Iran. Legal entities (companies) registered outside Iran follow different corporate tax rates under Article 105 and may be subject to withholding taxes under Article 86.

How to Calculate Rental Income Tax in Iran

The Iranian National Tax Administration (INTA) requires the conversion of all rental components into an annual IRR figure before applying statutory deductions and progressive rates. Mortgage deposits (Rahn) are strictly treated as taxable rent equivalents.

📋

Step 1: Determine Gross Annual Rent

Add all monthly cash rent received over the Iranian calendar year.
Convert the Rahn (mortgage deposit) to equivalent monthly rent using the official Central Bank or statutory conversion rate (typically 18% annually, divided by 12).
Multiply the total monthly equivalent by 12 to get the Gross Annual Rent.

📉

Step 2: Apply Statutory Deductions

Deduct 25% from the Gross Annual Rent for property depreciation, maintenance, and statutory expenses (Article 54).
The remaining 75% is your core Taxable Rental Income.

🛡️

Step 3: Apply Exemptions & Rates

If eligible under Article 57, subtract the annual Article 84 exemption threshold.
Apply the progressive rates of Article 131 (15%, 20%, 25%) to the remaining balance.

Calculation Stage	Formula / Action
Rahn Conversion	(Deposit Amount × 18%) ÷ 12 = Equivalent Monthly Rent.
Gross Annual Rent	(Monthly Cash Rent + Equivalent Monthly Rent) × 12.
Taxable Base (Art. 54)	Gross Annual Rent × 75%.
Final Tax Liability	Apply Art. 131 brackets to (Taxable Base - Art. 84 Exemption).

Example: Expat Apartment in Tehran

Assume an expatriate owns an apartment in Tehran. The lease agreement includes a Rahn deposit and monthly cash rent. We will calculate the annual tax liability based on standard IDTA rules.

Lease Component	Amount / Value	Tax Treatment
Monthly Cash Rent	50,000,000 IRR	Fully included in gross income.
Rahn Deposit	2,000,000,000 IRR	Converted: 2B × 18% ÷ 12 = 30,000,000 IRR equivalent monthly rent.
Total Monthly Equivalent	80,000,000 IRR	Base for annual calculation.
Gross Annual Rent	960,000,000 IRR	(80M × 12 months).
25% Statutory Deduction	(240,000,000 IRR)	Deducted under Article 54.
Taxable Base (75%)	720,000,000 IRR	Subject to Article 131 progressive rates.

Important Note on Rahn Conversion Rates

The 18% conversion rate is the standard statutory baseline used by the INTA and Central Bank directives. However, the tax authority may occasionally update this percentage or apply specific regional coefficients. Always verify the current conversion rate on the INTA portal before filing.

Exemptions and the Empty Homes Tax

Expatriates often assume that because they live abroad, their Iranian properties are exempt from local taxes. This is incorrect. However, specific exemptions exist for low-income landlords, while severe penalties apply to vacant properties.

Article 57 Exemption (Sole Income Rule)

1
Verify Income Sources
Confirm you have absolutely no other taxable income inside Iran (no salary, no business profits, no dividends).
2
Check Article 84 Threshold
Locate the annual exemption threshold announced by the INTA for the current Iranian calendar year.
3
Apply to Taxable Base
Subtract the Article 84 threshold from your 75% taxable rental base before applying Article 131 rates.

The Empty Homes Tax (Article 54 bis / 54 mokarrar)

If you leave your residential property empty while residing abroad, you are subject to the Empty Homes Tax. This is calculated as a multiple of the regional transaction value (Arzesh-e Moamelati) and is strictly enforced against owners registered as living outside Iran. You must register the property on the National Housing Database (Amlak va Eskan) to avoid severe automated penalties.

Filing Deadlines and Penalty Exposure

Under Article 100 and related provisions, the deadline to file the annual rental income tax return is the end of the month of Tir (approximately July 22) for the previous Iranian calendar year (which ends on Esfand 29/30). This deadline applies equally to expatriates.

Compliance Item	General Rule	Risk if Missed
Annual Tax Return	File via my.tax.gov.ir by the end of Tir (July 22).	30% penalty Under Article 192, failure to submit the return triggers a 30% non-forgivable penalty on the unpaid tax.
Tax Payment	Pay the assessed tax via the INTA portal or authorized banks.	2% per month Late payment triggers a 2% monthly penalty on the outstanding debt under Article 190.
Empty Homes Registry	Register property status on the Amlak va Eskan portal.	Heavy Fines Automated multiplication of regional value taxes for vacant units.

Practical Control — Use a Local Representative

Because the INTA portal requires Iranian authentication credentials (Sanaa system) and local bank cards for payment, most expats grant a limited Power of Attorney (PoA) to a trusted tax consultant or lawyer in Iran to handle the filing and payment before the Tir deadline.

Cross-Border Payment and Currency Issues

Expats frequently receive rent in foreign currency (USD, EUR, AED) via exchange houses (Sarafi) or keep it offshore. The INTA does not accept foreign currency for tax payments and calculates all liabilities based on the Iranian Rial (IRR) value of the lease.

IRR Calculation: The lease agreement must state the IRR equivalent, or the tax authority will assess the property based on regional market rates.
Payment Method: Taxes must be paid via the Iranian banking system using Shetab cards or direct bank transfers to the INTA treasury account.
Double Taxation Treaties (DTTs): Iran has active DTTs with several countries (e.g., Germany, France, Turkey, UAE). You can use your official INTA payment receipts to claim a foreign tax credit in your country of tax residence.
Repatriation of Funds: Ensure your rental income transfer complies with both Iranian Central Bank foreign exchange regulations and your home country's anti-money laundering (AML) reporting requirements.

Exchange Rate Fluctuations

If your lease is pegged to a foreign currency but paid in IRR, the INTA will tax the actual IRR received. However, massive disparities between declared rent and market reality can trigger an INTA audit and reassessment based on the regional transaction value.

Required Documents and Expat File Checklist

To successfully file your return and defend against potential audits, you must maintain a complete digital and physical file of your Iranian property activities.

📄

Core Legal & Lease Documents

Official Property Deed (Sanad-e Malekiyat) or certified copy.
Official lease agreements (registered with the Real Estate Consultants Union) or holographic contracts with witness signatures.
Proof of Rahn deposit transfers and monthly rent bank receipts.
Foreign Passport and Iranian National ID (if dual national) registered in the Sanaa tax portal.

🗂️

Tax & Representation Documents

Official Power of Attorney (PoA) granted to your Iranian tax representative.
INTA tax assessment sheets (Barg-e Tashkhis) and payment receipts.
Evidence of registration on the National Housing Database (Amlak va Eskan).
Double Taxation Treaty forms (if claiming credits in your home country).

Selling Property and Leaving Iran

If you decide to sell your Iranian property and repatriate the capital, you will face a different tax regime. Rental income tax must be cleared before the deed can be transferred.

1
Obtain Tax Clearance (Mafasa Hesab)
The notary public (Daftarkhaneh) cannot transfer the deed without a clearance certificate from the INTA proving all historical rental taxes are paid.
2
Pay the Transfer Tax (Article 59)
A flat transfer tax (usually 5% of the regional transaction value, not the market price) must be paid at the time of sale.
3
Capital Gains Considerations
While Iran does not currently have a comprehensive standalone Capital Gains Tax (CGT) on standard residential transfers, the Transfer Tax acts as the primary levy. Ensure your home country's tax authority recognizes this as a final property tax.

Foreign Ownership Restrictions

Under Article 1 of the Law on Ownership of Immovable Property by Foreign Nationals, foreign nationals generally require specific permits to own real estate in Iran. If your property was inherited or acquired under specific exceptions, ensure your legal status is documented to avoid frozen assets during the sale process.

Common Expat Mistakes

Most expatriate tax disputes arise from a misunderstanding of how the Iranian tax authority views foreign residency and offshore payments. The INTA taxes the source of the income (the physical property in Iran), not the residence of the landlord.

Ignoring the Rahn deposit: failing to convert the mortgage deposit into taxable equivalent rent.
Missing the Tir deadline: assuming expats have extended deadlines or are automatically exempt from filing.
Leaving properties empty: ignoring the Empty Homes Tax (Article 54 bis) for properties left vacant while living abroad.
Using offshore accounts only: failing to maintain an Iranian bank account or local representative to pay the INTA portal.
Assuming foreign currency is exempt: believing that receiving rent in USD or EUR bypasses IRR tax calculations.
Skipping the Sanaa registration: failing to register foreign passport details in the INTA judicial/tax portal, blocking electronic filing.
Losing payment receipts: failing to keep official INTA receipts needed to claim Double Taxation Treaty credits in the home country.

How is the Rahn (mortgage deposit) taxed?

The Iranian National Tax Administration (INTA) converts the Rahn deposit into an equivalent monthly rent using the official Central Bank or statutory conversion rate (typically 18% annually, divided by 12) and adds it to the gross monthly rent before applying deductions.

What is the filing deadline for expats?

The annual rental income tax return must be submitted electronically via the INTA portal by the end of the month of Tir (approximately July 22) for the previous Iranian calendar year.

Can I claim the annual tax exemption?

Under Article 57, natural persons who earn absolutely no other income besides rent in Iran may apply the annual individual exemption threshold stated in Article 84 to their taxable rental income.

What happens if I leave my property empty while abroad?

Leaving residential properties empty triggers the Empty Homes Tax (Article 54 bis / 54 mokarrar), which is calculated as a multiple of the regional transaction value and is strictly enforced against owners residing outside Iran.

How do I pay the tax if I live outside Iran?

Tax must be paid in Iranian Rials (IRR). Expats typically use a trusted legal representative with a Power of Attorney and an Iranian bank card to pay via the my.tax.gov.ir portal, or they arrange transfers through authorized local representatives.

Is there a Double Taxation Treaty (DTT)?

Iran has active Double Taxation Treaties with several countries. Expats can usually claim a foreign tax credit in their country of residence for the taxes paid to the Iranian government, provided they retain official INTA payment receipts.
