What Does Japan's 2028 Platform Tax Reform Mean for Foreign E-Commerce Sellers?

Japan's Phase 2 platform tax reform, effective April 2028, makes e-commerce platform operators the Japan consumption tax (JCT) taxpayer for cross-border B2C goods sold to Japan consumers, and abolishes the current JPY 10,000 de minimis exemption entirely. Foreign sellers must plan now for JCT assessed on every parcel, with structural representation on the ground needed to preserve their input credit chain.

What Is Japan's Platform Taxation Reform?

Platform taxation shifts JCT liability from the individual seller to the marketplace operator itself, under the Consumption Tax Act (消費税法). Japan is rolling this out in two phases rather than a single cutover.

Phase 1 took effect in April 2025 and applies to app-store-type digital platforms. Above a JPY 5 billion gross transaction volume threshold, operators such as the major app-store platforms became the JCT taxpayer for the digital service supplies flowing through their stores, replacing thousands of individual app developers as the point of tax collection. Phase 2, effective April 2028, extends the same logic to physical goods, which is the part that matters most for foreign e-commerce sellers.

What Changes in April 2028 Under Phase 2?

Phase 2 is a cross-border goods reform, not an expansion of the digital categories covered in Phase 1. Two changes land at the same time and reinforce each other.

First, the current JPY 10,000 de minimis exemption for cross-border B2C imported goods is abolished, so JCT applies regardless of parcel value. Second, platform taxation itself extends to cross-border B2C physical goods sold through e-commerce marketplaces: the platform operator becomes the JCT taxpayer for goods imported by individual Japan consumers through that platform, mirroring the Phase 1 digital-service model. A seller listing products through a marketplace serving Japan consumers should treat 2028 as the date the tax collection point moves away from the seller's own invoice and toward the platform's transaction record. For sellers who want the current-state de minimis mechanics before the reform, that ground is covered separately in our Japan Import De Minimis Threshold 2026 guide; this post does not repeat that detail.

Does the Reform Change How Sellers Reach Japan Consumers Today?

Not yet. Between now and April 2028, current rules continue to apply, and the reform's practical weight falls on how a seller structures representation and invoicing before the changeover, not on any immediate 2026 filing obligation.

The planning window matters because the input credit chain, invoice registration, and customs representation structures a seller adopts now will carry through the transition. Sellers who wait until 2028 to address representation will be reacting to a live JCT assessment rather than a planned one.

Why Do Foreign Sellers Need Customs Representation After 2028?

Once JCT is assessed at the platform or importer level rather than waived below a threshold, a foreign seller with no Japan address needs an Attorney for Customs Procedures (税関事務管理人 (ACP)) to remain the importer of record on paper while a Japan resident handles the customs-facing obligations. ACP's legal basis is Customs Act Article 95 (関税法第95条), which permits a non-resident to appoint a Japan-resident agent for customs procedures without establishing a Japan entity.

Without that representation, a non-resident seller has no address of record to satisfy Japan Customs' filing requirements, which breaks the chain needed to later claim JCT paid at import as an input credit. Structural alternatives exist, such as the Japan buyer becoming the importer and absorbing the JCT and credit claim itself, but that shifts customs risk onto the buyer and is a weaker position for a seller trying to compete on delivered price. Maintaining ACP representation keeps the seller named as importer while the JCT and credit mechanics are handled through proper Japan-side channels, which becomes materially more valuable once every parcel carries a JCT assessment rather than only shipments above JPY 10,000. Our companion guide on how non-resident IOR and ACP importers claim input tax credits walks through the credit recovery mechanics in more detail.

How Does the Qualified Invoice System Affect the Credit Chain?

The Qualified Invoice System (適格請求書, effective October 2023) determines which registered issuers can generate invoices that carry input tax credit downstream to the next party in a transaction chain. A non-registered issuer cannot pass on a usable credit, regardless of how the underlying JCT was assessed.

This matters for the 2028 reform because platform-level JCT collection adds a new party to the chain: the platform operator now sits between the foreign seller and the Japan consumer as the entity remitting JCT. Sellers relying on an ACP structure and a properly registered invoice issuer keep the credit chain intact end to end; sellers without either piece risk JCT being collected at the platform level with no corresponding credit reaching anyone positioned to claim it. Chain integrity, not the tax rate itself, is where most of the compliance risk in this reform sits.

Key points:

(a) Phase 1 (April 2025) made app-store platforms the JCT taxpayer for digital services above a JPY 5 billion volume threshold; Phase 2 (April 2028) does the same for cross-border B2C physical goods sold through e-commerce marketplaces.

(b) The JPY 10,000 de minimis exemption for cross-border imported goods is abolished under Phase 2, so JCT applies to shipments of any value from April 2028.

(c) Foreign sellers need ACP representation under Customs Act Article 95 and a registered Qualified Invoice Issuer in the chain to preserve input tax credit once JCT is assessed at the platform or importer level.

Frequently Asked Questions

Does the 2028 reform mean I need a Japan company to keep selling through e-commerce platforms?

No. The reform does not require incorporation. A foreign seller without a Japan entity can remain the importer of record by appointing an Attorney for Customs Procedures (ACP) under Customs Act Article 95, which keeps customs and tax representation in Japan without establishing a local company.

Will my e-commerce platform automatically handle JCT for me after April 2028?

The platform operator becomes the JCT taxpayer for the underlying goods transaction, but that does not automatically preserve your own input tax credit position. You still need a registered Qualified Invoice Issuer and proper customs representation in the chain to claim credit on JCT actually paid at import.

Is the JPY 10,000 de minimis threshold already gone, or does it end in 2028?

It is still in effect today. The abolition is scheduled for April 2028 as part of Phase 2 of the platform taxation reform; current parcels valued under JPY 10,000 continue to clear without JCT assessment until that date.

Conclusion

Japan's 2028 platform tax reform is a structural shift in who collects consumption tax on cross-border goods, not a rate change. Foreign sellers who build the representation and invoice-chain structure now, ahead of the April 2028 changeover, avoid scrambling to fix a broken credit chain once JCT applies to every parcel.
