Definition

India's regime for online information and database access services, taxing a foreign supplier on sales to Indian consumers.

Why it matters

Indian terms carry two systems at once: the tax act and the exchange-control regime, which define residence differently and govern different things. Satisfying one is not satisfying the other, and a bank will hold a transfer until both are.

The team at work in the open-plan office

What one system calls it and the other does not

The practical test is whether a position taken under one definition can be explained to the other authority without contradiction. Where it cannot, the mismatch is real and is dealt with before filing rather than after a query arrives.

Where it shows up in practice

Definitions are easier to hold onto once attached to a filing. OIDAR shows up in each of these.

How to use this

If OIDAR is in a notice you have received, bring the notice. The definition matters far less than what the sender is actually asking for. If that describes your position, the next step is a short call — not a form.

A definition earns its place only when it changes a decision. The ones on this site were chosen because each of them alters a filing, a deadline or a piece of evidence somewhere in a cross-border file, and the term pages say where.

Cross-border situations we are engaged for

Case study 1

A subscription business testing whether its service falls in the regime

The client sold a research product with a substantial analyst component alongside database access, and had assumed the human element took it outside the regime. The two parts were priced as one. We separated what the subscriber actually received, tested each part against the automated-delivery boundary, and concluded that the database access was caught even though the analyst work was not. The engagement produced a written classification, a pricing and invoicing structure that reflects the split, and a registration covering the part of the revenue that required it.

Case study 2

Separating business customers from consumers in a billing system

The client's checkout let buyers tick a box to say they were a business, and nothing was verified or stored. That left no way to support the recipient-accounts treatment applied to a large slice of Indian revenue. We specified the fields to capture, had registration numbers validated at the point of sale, and reconstructed what could be evidenced for the periods already filed. The work produced a corrected treatment for the transactions that could not be supported, a billing change, and a monthly report the finance team uses to check the split.

Case study 3

Quantifying and disclosing years of unregistered supplies to Indian consumers

The client had been selling into India since long before anyone in the business had heard of the regime. We rebuilt the customer base by location from the payment data, established which periods and which revenue fell within the regime, and prepared the disclosure with the calculation set out period by period. The engagement produced a registration with a defensible effective date, filed returns for the back periods, a documented interest and penalty position, and a note explaining the evidence relied on for customer location where the records were thinnest.

Case study 4

A platform carrying other people's content and asking who supplies the customer

The client hosted material produced by independent creators and took a share of each sale. Whether it supplied the consumer, or merely facilitated the creator's supply, decided whether the tax was its own obligation. We worked through the payment flow, the terms shown to the buyer, and who set the price and handled complaints, then took a position and documented the elements behind it. The work produced that position paper, changes to the buyer-facing terms so they describe the position taken, and a creator communication explaining what each side accounts for.

Case study 5

Aligning contracts and invoices with the position actually filed

The returns treated part of the Indian revenue as sold to businesses, while the master agreements and the invoices described the customer in terms that did not support it. A reviewer comparing the two would have found the contradiction before finding anything else. We rewrote the recitals and the invoice wording to name the recipient and the service consistently with the filing position, and corrected the periods where the documents and the return genuinely disagreed. The engagement produced consistent paperwork across the file and a short drafting note for future contracts.

Case study 6

Receipts held by a bank until the tax and remittance papers agreed

The client's Indian collections were sitting with its bank because the documentation supporting the movements did not match what had been declared. Indian practice puts the tax act and the exchange-control regime side by side, and a bank will wait until both are satisfied. We assembled the invoices, the registration and the return positions into one consistent set, answered the bank's queries from that set, and corrected the single filing that was genuinely inconsistent. The outcome was released funds and a standing document checklist for each future remittance.

Case study 7

Paid for Work Done in Canada While Living Elsewhere

Employment carried out in Canada is taxable here even where the employer and the bank account are not. The engagement establishes how many of the days were worked in Canada, applies the treaty employment article, and deals with the withholding the payer has already taken.

Case study 8

One Salesperson Abroad, and a Corporate Filing Obligation

A single employee with authority to conclude contracts can create a taxable presence for the whole company. The review tests what the person actually does against the treaty article, and where a presence exists, works out what profit is attributable to it.

Core International & Cross-Border Tax Services

International Tax Planning & Advisory

Strategy and compliance for income, assets and families spread across borders.

One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.

U.S. & Cross-Border Tax Returns

Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.

Expat & Emigration Tax

The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.

Non-Resident Canadian Tax

Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.

Transfer Pricing & BEPS

Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.

Cross-Border Estates & Trusts

Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.

Cross-Border Corporate Tax

Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.

India Tax for NRIs & Returning Residents

The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.

Canadian Tax with a Foreign Element

Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.

UAE Tax for Expats & Their Home Country

A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

Cross-Border Real Estate

Foreign property income and sales are taxed in both countries by default; Section 216, FIRPTA and treaty credits are the standing toolkit.

Property is taxed where it sits, which is the one rule no treaty overrides. What the treaty does decide is the credit, the rate on the rent and what happens on the sale — and the clearance certificate on a disposition is applied for before closing, not after the buyer has already held the money back.

OIDAR — the questions that follow

Do I have to register in India to sell digital services there?

If your customers are consumers in India and what you supply falls within the regime, registration is the starting assumption rather than the exception. The regime exists precisely because the supplier is abroad and outside the ordinary collection machinery, so the obligation is placed on the foreign supplier directly. What has to be settled first is whether your service is of the kind covered, and whether the customers concerned are consumers or businesses, because that answer decides who accounts for the tax.

What kinds of services count as OIDAR?

Broadly, services delivered over a network whose supply is essentially automated and needs little or no human intervention: access to databases, downloadable content, software provided as a service, advertising space and similar. The boundary sits where human involvement becomes more than incidental, because a service performed by people and merely delivered electronically is generally a different thing. That line is where most disputes are found. It is worth testing your own product against it deliberately, with the customer-facing description and the technical reality both in front of you.

Who pays the tax if my Indian customer is a business?

Where the recipient is a registered business, a regime of this kind generally asks the recipient to account for the tax instead of the foreign supplier. The supplier's difficulty is proving which customers those were. A registration number captured at the point of sale and stored with the transaction is what supports the treatment later; a claim made at checkout and never verified is not. Businesses and consumers therefore need to be distinguishable in your billing data, not merely in your commercial understanding of who buys from you.

Can a foreign company register in India without an Indian entity?

Yes. The regime is built for suppliers with no presence in the country, and the registration route reflects that. Many suppliers appoint a representative in India to hold the registration and to file, which is often the practical answer even where it is not compulsory, because the returns, the notices and any query all arrive locally. The mechanics are amended from time to time, so confirm the current route before committing to a structure. Keep the question separate from whether the business has an income tax presence in India, which is decided under different rules.

How do I prove my customer is in India?

With evidence collected at the time of the sale and kept with it. The billing address, the country of the payment instrument, the network address used and the country code of a mobile number are the usual indicators, and the point is to record what you relied on rather than to find a single perfect test. Where indicators conflict, note which one governed and why. This part of the regime is administrative rather than technical, and it is the part that decides whether a position can be defended when a period is examined years later.

I have sold to Indian consumers for years without registering. Now what?

Deal with it deliberately, rather than registering quietly from today and hoping the history is not asked about. The first task is to measure it: which sales were to consumers, in which periods, on what evidence. The size and shape of the exposure decides the approach. India's disclosure and assessment machinery treats a taxpayer who arrives with a quantified position very differently from one who is found. Expect interest and penalty exposure to form part of the outcome, and expect the exchange-control side of the money already received to need its own answer.

Branch or subsidiary — which should we use to expand?

A branch keeps one taxpayer: results consolidate at home, losses are usable sooner, and the exposure is that the branch is a permanent establishment whose profit the host country taxes, sometimes with a branch tax on repatriation. A subsidiary is a separate taxpayer with limited liability and local rates, at the cost of withholding on dividends home and transfer pricing on everything between them. The deciding facts are usually expected losses, liability and exit plans. See branch against subsidiary.

What happens if the two countries disagree about which of them can tax me?

The treaty has a procedure for exactly that. You apply to the competent authority in your residence country, which takes the case up with its counterpart, and the two negotiate a position that removes the double taxation. Some treaties add binding arbitration if they cannot agree. It is slow and it runs on documents, so the practical work is preserving the record and filing protective claims while the clock runs.
