Japan Invoice System News: What Businesses Need to Know in 2026

Japan's qualified invoice system (適格請求書等保存方式, tekikaku seikyusho nado hozon houshiki or インボイス制度, innboisu seido) has reshaped how businesses handle consumption tax since its launch in October 2023.

Whether you are a startup, a sole proprietor, or a global company with a Japan presence, staying on top of Japan invoice system news is critical to protecting your tax credits and avoiding compliance penalties.

This guide covers everything you need to know: what the qualified invoice system requires, which transitional measures are changing in 2026, how to register as a qualified invoice issuer, and what steps to take now to keep your business compliant.

What is the qualified invoice system?

The qualified invoice system is a method for businesses to receive a purchase tax credit on their consumption tax.

It replaced the previous "ledger-based" system on October 1, 2023, and requires that businesses retain qualified invoices issued by registered issuers in order to claim input tax credits.

Under this new invoice system, only invoices issued by a registered qualified invoice issuer are eligible for claiming the purchase tax credit.

This means buyers must verify that their suppliers hold a valid registration number before assuming they can deduct consumption tax paid on those transactions.

The Japanese government introduced this system to improve the accuracy and transparency of consumption tax collection, particularly after Japan adopted two consumption tax rates (a standard 10% rate and a reduced 8% tax rate for food and beverages) in October 2019.

Why was the new system introduced?

Before October 2023, businesses could claim a purchase tax credit based on ledger entries alone, regardless of whether their supplier was actually paying consumption tax.

This meant that a tax-exempt business (one with annual taxable sales under 10 million yen) could collect consumption tax from customers and keep the full amount of consumption tax as additional income, while the buyer still claimed a tax credit.

Now, only invoices issued by registered businesses can support a valid input tax credit.

This ensures that the consumption tax amount listed on an invoice reflects the tax that the company actually reports to the tax office.

What must a qualified invoice include?

A qualified invoice must contain the following information to be considered valid:

1. Name and registration number of the qualified invoice issuer

2. Transaction date (the date of the supply of goods or services)

3. Description of the goods or services delivered

4. The applicable tax rate for each line item (either 8% or 10%)

5. The consumption tax amount broken down by tax rate

6. Name of the buyer (the business receiving the goods or services)

If any of these transaction details are missing, the document does not qualify as a valid invoice under the system.

The buyer would then be unable to apply the full purchase tax credit, which increases their overall consumption tax liability.

Who needs to issue qualified invoices?

Any business that is paying consumption tax and wants its customers to be able to claim the purchase tax credit should register as a qualified invoice issuer.

This is especially important for businesses whose customers are other businesses (B2B transactions), since those customers need qualified invoices to deduct the consumption tax on their taxable purchases.

Businesses that primarily serve general consumers (B2C) may not face the same pressure, since individual consumers are not eligible to claim the purchase tax credit.

However, registration is still recommended for businesses that handle a mix of business transactions and consumer sales.

How to register as a qualified invoice issuer

To become a qualified invoice issuer, a business must submit a registration application to the tax office. Here is the process:

1. Submit the "Application for Registration of Qualified Invoice Issuer" to your local tax office or through the National Tax Agency's e-Tax online system

2. The National Tax Agency reviews the application and assigns a registration number

3. Once registered, the business is listed in a public database maintained by the National Tax Agency

4. The business must then include its registration number on all invoices issued going forward

For foreign companies not based in Japan, online registration through e-Tax requires a Digital ID, which requires a legal presence in Japan.

However, a paper application is also accepted.

The National Tax Agency (NTA) provides English-language guidance and paper forms for this process.

It is important to note that registering as a qualified invoice issuer also means the business becomes liable for paying consumption tax, even if it was previously a tax-exempt business.

This is a significant consideration for sole proprietors and small businesses with annual sales under 10 million yen.

Transitional measures: What is changing in 2026?

One of the most important areas of Japan's invoice system news right now concerns the transitional measures the Japanese government has put in place to soften the impact of the new system.

Under these transitional measures, buyers can still claim a certain percentage of the purchase tax amount on taxable purchases from suppliers who are not registered qualified invoice issuers (including tax exempt businesses and sole proprietors who have not registered).

Current transitional credit schedule

The credit rates are structured as follows:

• October 1, 2023 to September 30, 2026: 80% of the purchase tax amount is deductible

• October 1, 2026 to September 30, 2029: 50% of the purchase tax amount is deductible

• After September 30, 2029: 0% deductible. Only qualified invoices from registered issuers will support any input tax credit

This means October 2026 is a critical deadline.

Starting that month, the deductible percentage drops from 80% to 50%, significantly increasing the cost of doing business with unregistered suppliers.

2026 tax reform: Extended timeline and new measures

The fiscal year 2026 tax reform outline, released by the Japanese government in December 2025, introduced several revisions to the qualified invoice system's transitional measures:

Extended phase-out schedule: The transitional measure for purchase tax credits on purchases from tax exempt businesses has been extended by two years. The revised phase-out schedule is:

• October 1, 2026 to September 30, 2028: 70% deductible

• October 1, 2028 to September 30, 2030: 50% deductible

• October 1, 2030 to September 30, 2031: 30% deductible

• After September 30, 2031: 0% deductible

New 30% special measure for small businesses: After the original "20% special measure" (which allowed newly registered small-scale enterprises to pay only 20% of their sales tax) concludes, a new two-year transitional measure will apply. Under this measure, small business operators who became qualified invoice issuers can set their tax liability at 30% of the consumption tax on their taxable sales for a certain period.

Cap on transitional credits: For purchases from non-qualified invoice issuers, if the total purchase amount from one non-qualified issuer exceeds 100 million yen in a single tax period, the portion exceeding that threshold cannot use the transitional credit. This change is expected to take effect for tax periods starting from October 1, 2026.

These updates are particularly important for businesses that rely on a network of small suppliers, freelancers, or sole proprietors who may not yet be registered.

How does the invoice system affect small businesses?

The introduction of the qualified invoice system has had an outsized impact on small businesses and sole proprietors in Japan.

The tax-exempt business dilemma

Under the old system, businesses with annual taxable sales below 10 million yen were classified as tax-exempt.

They collected Japanese consumption tax from their customers but were not required to file consumption tax returns or remit the tax to the government. In effect, the consumption tax paid by their customers became additional income.

Under the new system, if a tax-exempt business does not register as a qualified invoice issuer, its customers can no longer claim the full purchase tax credit on transactions with that business. During the transitional period, customers can still claim a reduced percentage, but this credit will phase down to zero.

This creates pressure on tax-exempt businesses to register. But registration means they must begin paying consumption tax to the government, reducing their effective income.

What should small businesses do?

The decision depends on the nature of the business:

• B2B businesses (those whose customers are other businesses) face the strongest incentive to register. If your customers need qualified invoices to claim their input tax credit, not registering could mean losing contracts or clients.

• B2C businesses (restaurants, cafes, retail shops, language schools, taxis) that primarily serve general consumers may face less urgency, since individual consumers do not claim the purchase tax credit. However, mixed businesses should carefully evaluate their customer base.

• Sole proprietors and freelancers should weigh the cost of becoming a taxable business against the risk of losing clients who require issuing qualified invoices. The transitional measures provide a buffer, but the credit rate will continue to decline.

Peppol and E-invoicing in Japan

Another significant area of japan invoice system news is the Japanese government's push toward electronic invoicing through the Peppol network.

What is peppol?

Peppol (Pan-European Public Procurement On-Line) is an international standard for exchanging business documents in electronic format. Japan's Digital Agency, acting as the Japan Peppol Authority, has adopted the Peppol International Invoice (PINT) standard as the basis for structured e-invoicing in Japan.

How does peppol work in Japan?

The Japanese standard (known as JP PINT) is based on Peppol BIS Billing 3.0, adapted to meet local requirements such as the qualified invoice fields.

While e-invoicing is not yet mandatory in Japan, the government strongly encourages businesses to adopt it. Issuing invoices in electronic format through the Peppol network offers several advantages:

• Faster processing and reduced manual data entry

• Built-in compliance with qualified invoice requirements

• Compatibility with accounting systems that support structured data

• Simplified storage under the Electronic Book Preservation Act (ERRL / 電子帳簿保存法)

Since January 2024, any invoice issued or received electronically must be stored in a digital format that meets the ERRL requirements. Printing a digital invoice and storing it on paper is no longer compliant.

Compliance checklist for 2026

With the October 2026 changes approaching, here is what businesses operating in Japan should do now:

1. Confirm your registration status. If you have not already registered as a qualified invoice issuer, evaluate whether registration makes sense for your business. Submit your application through the National Tax Agency's e-Tax portal or by paper.

2. Audit your supplier list. Verify that your key suppliers hold valid registration numbers. Purchases from unregistered suppliers will only be 50% deductible (under the original schedule) or 70% deductible (under the revised 2026 reform schedule) starting in October 2026.

3. Update your invoicing templates. Make sure every invoice you issue includes all required fields: your registration number, the transaction date, a description of goods or services, the applicable tax rate, the consumption tax amount by rate, and the buyer's name.

4. Review your accounting systems. Your systems need to capture and store qualified invoices in compliance with the Electronic Book Preservation Act. If you are still using paper-based processes, now is the time to transition to digital.

5. Understand the transitional measures. Know which credit percentages apply to your current tax period and plan your supplier relationships accordingly.

6. Consider Peppol adoption. If your business handles a high volume of invoices, adopting JP PINT-compliant e-invoicing through a certified Peppol service provider can reduce errors and simplify compliance.

Frequently Asked Questions

What happens if I do not register as a qualified invoice issuer?

Your customers will not be able to claim the full purchase tax credit on their transactions with you. During the transitional period, they can still claim a reduced percentage (currently 80%, dropping to 70% from October 2026 under the revised schedule). After the transitional measures end, no credit will be available for purchases from unregistered businesses.

Can a tax exempt business register for the qualified invoice system?

Yes. A tax exempt business can register as a qualified invoice issuer. However, doing so means the business becomes a taxable enterprise and must begin paying consumption tax to the government. The 2026 tax reform includes a new transitional measure allowing newly registered small businesses to set their tax liability at 30% of sales tax for a limited two-year period.

Is e-invoicing mandatory in Japan?

No. As of 2026, e-invoicing is not mandatory for all Japanese businesses. However, the government is actively promoting adoption through the Peppol network and JP PINT standard. Businesses that issue or receive invoices electronically must store them digitally under the Electronic Book Preservation Act.

What is the Peppol network and do I need to use it?

Peppol is an international standard for exchanging business documents electronically. Japan's Digital Agency serves as the Peppol Authority and has developed the JP PINT specification for structured e-invoicing. While not required, adopting Peppol can streamline compliance and reduce manual processes, especially for businesses handling large volumes of invoices.

How does the qualified invoice system affect foreign companies doing business in Japan?

Foreign companies engaged in taxable activities in Japan (such as providing services within the country) may be asked by Japanese counterparts to register as qualified invoice issuers. For companies without a legal presence in Japan, registration is possible through a paper application to the National Tax Agency. A virtual office address from a provider like MailMate can support the registration requirement for a physical address in Japan.

What are the two consumption tax rates in Japan?

Japan has two consumption tax rates: a standard rate of 10% and a reduced rate of 8%. The reduced tax rate applies to food and beverages (excluding dining out and alcohol). Qualified invoices must list the applicable tax rate and the consumption tax amount separately for each rate category.

In Closing

Japan's qualified invoice system is no longer new, but it is far from finished.

The October 2026 deadline marks the next major shift, with reduced credit rates for purchases from unregistered suppliers, new transitional measures for small businesses, and growing momentum behind e-invoicing through the Peppol network.

The businesses that come out ahead will be the ones that act before the deadlines hit. That means confirming your registration status, auditing your supplier list, updating your invoicing templates, and making sure your document storage meets ERRL requirements.

If you are managing a Japan-based business from overseas, the compliance burden is even heavier.

Tax office notices arrive in Japanese. Invoice deadlines do not wait for time zones. And paper-based processes that worked five years ago no longer meet the legal standard.

MailMate was built for exactly this situation. We scan, translate, and store your Japanese mail and invoices in one place, pay your bills on time, and keep your documents ERRL-compliant so you are always audit-ready.
