Tax for Online Businesses and E-Shops in Iran

Many e-shop owners and startup founders assume that without a physical shop or trade licence there is no tax file to worry about. This article explains why that assumption is expensive, which obligations begin in your first month of sales, and how to build a defensible structure from the start.

How the law sees online sales

Tax attaches to economic activity and income, not to the appearance of a workplace. If you sell goods or services through a website, an app, an Instagram page or a marketplace, you carry the same obligations as a physical store.

The difference is visibility. Payment gateway transactions, trust symbol records, payment service provider data and shipping records all reconcile against each other. In the files I have handled, this is the source of most disputes: the seller assumed invisibility and later faced an assessment without the documents to defend it.

Sole trader or company?

Choose on expected volume, the need to contract with larger companies and any plan to raise investment — not on the headline rate alone. For smaller operators, the simplified route is covered in the Article 100 simplified assessment guide.

Getting properly set up

1. Decide the legal structure and register a company if appropriate.
2. Open the tax file and obtain the economic code.
3. Open a business bank account and stop using personal accounts for sales entirely.
4. Obtain the electronic trust symbol for the site or app.
5. Set up an official payment gateway linked to the business's tax identity.
6. Register for VAT if you fall within scope.
7. Implement electronic invoicing and connect to the taxpayer portal.
8. Install accounting software that handles orders, returns, discounts and shipping charges.
9. Build a written calendar of monthly and quarterly obligations with a named owner for each.

Which taxes apply

Registration thresholds and return mechanics follow the general VAT rules.

Electronic invoicing pitfalls for e-shops

• Returns and cancellations are frequent online; your system must issue corrective and cancellation invoices.
• Shipping charges: decide whether they form part of the sale or a separate service, and stay consistent.
• Item codes: assign standard goods and services identifiers from day one, not after ten thousand orders.
• Cash on delivery: define in writing when revenue is recognised and the invoice issued.
• Marketplace sales: recognise gross revenue and record the platform commission as an expense, rather than booking only the net settlement.

The scope and phasing of these requirements are explained in the taxpayer system guide.

Gateways and bank accounts

An official gateway is both a trust signal for customers and the clearest evidence of your revenue. That transparency becomes dangerous only when part of your sales runs through card-to-card transfers and never reaches the books. A gap between banking turnover and declared revenue is the first thing an assessor looks at. The boundary between personal and business banking is discussed in bank transactions and tax scrutiny.

Deductible costs often overlooked

Digital advertising, cloud and hosting subscriptions, gateway and marketplace commissions, packaging and delivery, design and development fees, and content production are all deductible — provided there is valid documentation, a contract and a traceable payment route. Services purchased from abroad frequently get disallowed for lack of a formal invoice or a bankable payment trail, so keep alternative evidence (contract, payment receipt, correspondence) from the outset.

Incentives worth planning for

Two routes matter for digital businesses: knowledge-based status with a science and technology park, and the exemption for exported services. Both carry specific qualifying conditions and documentation, and both need planning before the fiscal year ends rather than at filing time. Confirm current qualifying conditions and thresholds against the latest circular.

If you are launching or formalising an online business and want the tax structure right from the start, I am glad to review it with you.

Key takeaways

• Having no physical shop removes no tax obligation.
• Open the tax file and business account before selling, not after growth.
• Define returns, shipping and marketplace commission in your invoicing policy on day one.
• Discrepancies between banking turnover and declared income drive most online-seller assessments.
• File returns even in loss years, or you forfeit loss carry-forward and face an unwaivable penalty.
