Since October 2023, Japan's qualified invoice system has changed how consumption tax credits work. Here is what it means for sellers on Amazon.co.jp, both domestic and overseas.
The basics of the qualified invoice system
Japan introduced the Qualified Invoice System, often called the invoice system, on October 1, 2023. Under it, a business purchaser can generally claim input tax credits for consumption tax only if it holds a qualified invoice issued by a registered issuer. Registered issuers receive a registration number consisting of the letter T followed by thirteen digits, which must appear on their invoices.
A qualified invoice must include specific items: the issuer's name and registration number, the transaction date, a description of the goods or services, the amounts broken down by tax rate, the applicable tax rates and the consumption tax amounts, and the recipient's name. Japan has a standard rate of 10 percent and a reduced rate of 8 percent that applies mainly to food and beverages other than alcohol and dining out, as well as certain newspaper subscriptions.
Registration is voluntary, but only taxable businesses can register. Small businesses that were previously exempt from consumption tax must become taxable to register, which is why the system prompted many small sellers to reconsider their status.
Why it matters for Amazon.co.jp sellers
For sellers whose customers are mainly consumers, the immediate impact is limited, because individual consumers do not claim input tax credits. However, a meaningful share of Amazon.co.jp purchases are made by businesses, including through Amazon Business. Those buyers may prefer, or require, sellers who can issue qualified invoices, and Amazon displays information about whether sellers support invoice issuance.
On the cost side, Amazon's own fees, such as referral fees, FBA fees and advertising charges, are subject to consumption tax. Sellers who are taxable businesses need qualified invoices from Amazon for these fees to claim the corresponding input tax credits. Amazon provides tax documents for its fees through Seller Central and its advertising console; sellers should confirm they are downloading and retaining them.
Overseas sellers are not automatically outside the system. A foreign business selling goods stored in Japan, for example in FBA warehouses, may have consumption tax obligations and may choose to register. The rules for non-resident businesses, including the need for a tax representative in some cases, should be checked with a Japanese tax professional.
Registration, transitional measures and special rules
Several transitional measures soften the change. For a period after introduction, purchasers can still deduct a portion of the consumption tax on purchases from unregistered businesses, with the deductible share stepping down over time. Small businesses that became taxable in order to register were also given simplified calculation options for a limited period. These measures have defined end dates, so check whether the ones relevant to you are still in effect.
Simplified tax calculation (the simplified taxation system based on deemed purchase rates) remains an option for smaller taxable businesses that meet the conditions, and can reduce the administrative burden of tracking every input invoice. Whether it is advantageous depends on the actual cost structure of the business.
Because thresholds, deadlines and transitional percentages are set by law and revised from time to time, sellers should rely on the National Tax Agency's current guidance and their tax advisor rather than on summaries, including this one.
Operational checklist for sellers
If you are registered, enter your registration number in Seller Central so that it can be shown to buyers and used in invoice issuance. Make sure product tax codes are set correctly so that items subject to the reduced rate are calculated at 8 percent and everything else at 10 percent. Errors in tax rate settings flow directly into incorrect invoices.
Decide how you will issue invoices for orders. Amazon offers functionality to generate invoices on behalf of sellers in some cases, and third-party tools can also do this. Whatever method you use, confirm that the invoices contain all required items and that you can reissue or correct them when needed.
Retain records properly. Japan's Electronic Book Preservation Act sets requirements for storing electronically received transaction data, which includes invoices and fee statements downloaded from Amazon. Store documents in a searchable, tamper-evident way and keep them for the legally required period.
Automating compliance tasks
Much of invoice-related work is repetitive: downloading monthly fee invoices from Amazon, reconciling settlement reports with accounting records, checking tax codes on new listings and handling buyer requests for invoices. These are well suited to automation, with accountants reviewing the outputs rather than collecting the data.
Data from SP-API reports, including settlement and order data, can be fed directly into accounting systems with tax rates correctly assigned. Automated checks can flag listings with missing or inconsistent tax codes before they generate incorrect invoices.
KeyCenter helps sellers automate data collection and reconciliation around Amazon operations, but we are not a tax advisor. Always confirm your registration status, invoice format and tax treatment with a qualified Japanese tax professional.
