Inheritance Tax in Iran: What Heirs Actually Have to Do
This article is for heirs facing an Iranian estate file for the first time, and for advisers who want the sequence straight. In the files I have handled, the extra cost heirs end up paying almost always traces to two things: missing the one-year filing deadline, and not realising that most assets are valued at the date of transfer, not the date of death.
The structural change since 1395
For deaths up to the end of the Iranian year 1394, the entire estate was pooled, each heir's share was computed, and a progressive rate applied. From 1395 onward the system changed completely. There is no longer a progressive scale over the whole estate. Instead, each asset class carries its own flat rate, and the tax on that asset is assessed and collected at the moment it is transferred.
The practical consequence matters: heirs do not need to settle the bank deposits, the car and the shares before transferring a shop. Each asset follows its own track. That flexibility, however, hides a trap covered below.
Heir classes
| Class | Who | Rate multiple |
|---|---|---|
| First | Parents, spouse, children, grandchildren | Base Article 17 rate |
| Second | Grandparents, siblings and their children | Twice the first class rate |
| Third | Uncles, aunts and their children | Four times the first class rate |
Rates by asset type
The following apply to first class heirs:
| Asset | Rate | Valuation basis |
|---|---|---|
| Bank deposits, participation bonds and their yield | 3% | Balance up to the transfer registration date |
| Shares and partnership interests | 1.5 times the Article 143 rate | Rules in force on the transfer date |
| Real property and goodwill rights | 1.5 times the Article 59 rate | Official transaction value / current value of goodwill |
| Motor vehicles | 2% | Value announced by the tax administration |
| Licences, concessions and other financial rights | 10% | Current value at delivery or transfer |
| Foreign assets of an Iranian decedent | 10% | Estate value net of foreign tax paid |
Two cautions. Listed and unlisted shares carry different base rates under Article 143, and the 1.5 multiple applies to whichever rate is in force — confirm the current figure in the latest circular. For real property, the base is the official transaction value set by the property valuation commission, not the market price, and that schedule is revised annually.
Most assets are valued as at the transfer date, not the date of death. In an inflationary economy every year of delay in transferring a property raises the taxable base. This is the single most expensive mistake I see in estate files.
Exemptions and deductions
Article 24 places several items entirely outside the charge: pension and retirement funds, end-of-service benefits, severance and unused leave payouts; insurance proceeds for life policies, death compensation and blood money; assets bequeathed or endowed to qualifying public institutions; and the household furnishings of the deceased's residence.
Separately, proven debts of the deceased, religious financial obligations and reasonable funeral expenses reduce the estate. This deduction is not automatic. It must be declared in the return and supported by acceptable evidence — a contract, a promissory note, a court judgment, an invoice. Heirs who miss the filing deadline effectively lose access to it.
The sequence, step by step
- Obtain the death certificate from the civil registry.
- Apply for the certificate of inheritance from the dispute resolution council of the deceased's last residence.
- Compile a full schedule of assets and liabilities: property, vehicles, deposits, shares, partnership interests, receivables, licences and debts.
- Request formal enquiries through the tax office to trace accounts and securities; banks will not answer heirs directly.
- File the inheritance tax return within one year of death with the tax office of the last legal residence.
- After assessment, obtain the Article 34 clearance certificate for each asset you intend to transfer.
- Pay the tax on that asset, or apply for instalments.
- Present the certificate to the notary, bank, company registrar or vehicle transfer centre and complete the transfer.
Banks, notaries and companies must demand the tax administration's certificate before releasing or transferring a deceased person's assets. If they do not, they become liable for the tax themselves — which is why there is no shortcut around this step.
What makes estate files expensive
Late filing. A year sounds generous, but family disagreements and the time needed for the certificate of inheritance consume it quickly. Losing it means losing the debt and expense deductions.
Sitting on untransferred assets. Some heirs leave title unchanged for years, assuming the tax is merely deferred. In reality the valuation base climbs with current values and the final bill grows.
Ignoring debts. Documented liabilities of the deceased reduce the base. Failing to declare them means paying tax on wealth the heirs never received.
Family company interests. Where the estate includes a partnership interest, its value is derived from the company's books and financial statements. If the books are disorderly, the valuation goes against the heirs — one more reason disciplined statutory bookkeeping pays off long before anyone thinks about estate tax.
Rental property. Rent earned between death and transfer is income of the heirs and carries its own rental income tax obligation.
If the assessment notice differs materially from your own calculation, treat the 30-day objection window as hard: once the file becomes final, the appeal route is closed.
Key takeaways
- Since 1395, each asset class has its own rate and is taxed when that asset is transferred.
- Second class heirs pay double and third class heirs pay quadruple the base rate.
- The return is due within one year of death and unlocks the debt and expense deductions.
- Valuation generally follows the transfer date, so delay increases the tax.
- No bank, notary or company may transfer estate assets without the Article 34 certificate.
