India GST for Japanese Companies: OIDAR Rules Explained

Not sure if your India revenue clears the wrong threshold?

Japan's threshold doesn't apply here — see Section 2.

Executive summary

Japan's Consumption Tax on digital services is one of the more established regimes globally, in force since 2015. Two of its specific features — a real threshold and an unusual classification test — don't carry over to India.

What you need to know

Japan's Consumption Tax (JCT) applies 10% to non-resident digital service providers selling to Japanese consumers, in force since October 2015.
Japan has a ¥10 million threshold (roughly USD 65-70K). India's OIDAR has none.
Japan classifies B2B vs. B2C based on how the contract was negotiated, not simply whether a tax ID was captured — genuinely unusual, and worth understanding on its own terms.
Since April 2025, large digital platforms (over ¥5 billion in facilitated sales) become the deemed supplier under Japan's Platform Taxation Regime.

The concept you already know: JCT

If your company already complies with Japan's own Consumption Tax on digital services, the underlying architecture of OIDAR will feel familiar.

The parallel

Japan's JCT applies to non-resident providers of "electronic services" — e-books, music, video, software, cloud services, apps — supplied to Japanese consumers, taxed at the same 10% rate as domestic supplies. This destination-based structure, in force for a decade, is architecturally close to what OIDAR does for India: identify the consumer's location, apply the local rate, remit locally.

If your company already tracks Japanese-consumer status, applies JCT at checkout, and files with Japan's National Tax Agency, the operational muscle memory transfers directly to assessing your India position — just adjusted for materially different specifics, covered next.

Japan's ¥10 million threshold vs zero

The most consequential practical difference.

Common mistake

Assuming that because your India revenue sits comfortably under a level that would exempt you in Japan (¥10 million, based on a two-year-prior base period), a similar exemption exists in India. It doesn't. OIDAR has no threshold whatsoever — a single Indian customer creates the obligation, regardless of your company's total turnover or the size of your India revenue specifically.

Professional tip

If your internal risk register has ever noted "India revenue too small to matter, similar to our Japan position," treat that conclusion as suspect specifically — it's very likely importing Japan's threshold logic into a market that has none.

The contract-based B2B test

This is genuinely unusual among the jurisdictions covered on this site, and worth understanding precisely so it isn't accidentally applied to India.

How Japan actually draws the line

Most jurisdictions, India included, treat a sale as B2B once the customer provides a valid tax registration number. Japan looks instead at how the transaction was negotiated: a standardised, click-through, self-serve purchase is treated as B2C — requiring JCT collection — even when the buyer is a registered business. Only individually negotiated contracts with verified business customers qualify for B2B treatment in Japan.

India's approach is the more conventional one: capture a valid GSTIN at checkout, and the transaction is treated as B2B under reverse charge — the negotiation style is irrelevant. Don't let Japan's contract-based test influence how you build classification logic for India; a self-serve business customer with a valid GSTIN is genuinely B2B in India, unlike the equivalent scenario in Japan.

Professional tip

If your billing system has special-cased Japan's contract-based logic, make sure that logic is scoped specifically to Japanese customers and doesn't leak into your India classification rules — the two systems require genuinely different tests.

The platform deemed-supplier rule

If you operate a platform, Japan's own recent reform gives you a useful, current head start.

Japan's Platform Taxation Regime (from April 2025)

Once a digital platform's facilitated sales exceed ¥5 billion, the platform — not the underlying foreign supplier — becomes the deemed supplier responsible for filing and paying JCT. Foreign providers selling through such a designated platform are relieved of the qualified-invoice requirement for those specific transactions.

India's approach, covered in full on our Marketplaces & Advertising guide, uses a four-condition conduct test rather than a revenue-threshold trigger — but the underlying question is the same one Japan's reform now asks of large platforms: are you a genuine facilitator, or has your operational role made you the substantive supplier?

Checklist

Work through this specifically

Discard the ¥10 million threshold logic for India — it has none
Confirm your India B2B classification uses GSTIN capture, not Japan's contract-negotiation test
Rebuild your India rate model independently — don't scale from Japan's 10% baseline
If you operate a platform, apply India's four-condition intermediary test specifically
Use our applicability checker to confirm your specific position

Common questions

Do Japanese Companies have to pay tax in India?

If you sell digital services to customers in India, yes — but not income tax. The charge is GST, under India's OIDAR rules, and it applies to the sale rather than to your profits. There is no registration threshold: a single Indian consumer paying a small amount creates the obligation from that first sale. The rate is 18%. Where your Indian customer is a GST-registered business that gives you its GSTIN, the customer accounts for the tax instead under reverse charge and you do not collect it. Where the customer is a consumer or an unregistered business, you must register in India, charge 18%, and file a monthly return. Your home-country tax treaty does not remove this, because treaties cover income tax, not GST.

We have received an OIDAR GST notice from India — what should we do?

Treat it as time-bound. A Show Cause Notice carries a fixed response window, and if it passes without a reply the authority can decide the matter without hearing you, which is far harder to undo than it is to answer in time. Do not ignore it because your company has no Indian entity or presence — that does not limit the demand. Establish first what the notice actually is, since a routine enquiry, a DRC-01 and a Show Cause Notice carry different deadlines and consequences. Pull together your India revenue by period, your customer classification, and any GSTINs you captured, because the reply stands or falls on that evidence.

About this guide & sources: This guide reflects the position as at July 2026, drawing on Japan's National Tax Agency published guidance on Consumption Tax and the Platform Taxation Regime. It is provided for general information and does not constitute professional advice — Japanese JCT and Indian OIDAR obligations should each be assessed on their own specific facts.
