OIDAR GST in India:
A Guide for Japanese Companies

Japan's own Consumption Tax has run since 2015 — with a threshold and an unusual contract-based B2B test. India has neither.

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

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.

Confident about JCT, less sure about India's OIDAR?

The instincts partly transfer — the threshold and classification rules don't. Free initial assessment, no obligation.
