Current State of the Invoice System — Two and a Half Years In
Japan's Qualified Invoice System (tekikaku seikyusho tou hozon houshiki), launched on October 1, 2023, has now been in operation for two and a half years as of April 2026. The registration system for qualified invoice issuers under Article 57-2 of the Consumption Tax Act represents a fundamental reform of Japan's consumption tax framework, with particularly significant impacts on tax-exempt businesses (those with annual taxable sales of 10 million yen or less).
According to data published by the National Tax Agency, the cumulative number of registered qualified invoice issuers has exceeded 4 million. However, many formerly tax-exempt businesses that chose to convert to taxable status have struggled with the increased administrative burden of consumption tax filing and payment.
Transitional Measures and the October 2026 Reduction
To facilitate the transition to the invoice system, transitional measures for input tax credits on purchases from tax-exempt businesses were established (Articles 52 and 53 of the Supplementary Provisions of the 2016 Amendment Act).
| Period | Credit Rate |
|---|---|
| October 2023 – September 2026 | 80% creditable |
| October 2026 – September 2029 | 50% creditable |
| October 2029 onward | Not creditable (0%) |
Currently, 80% of input tax on purchases from non-registered businesses can be credited. From October 1, 2026, this drops to 50%, increasing the effective tax burden on taxable businesses that transact with tax-exempt suppliers and potentially accelerating changes in business relationships.
Estimated Financial Impact
For example, if taxable Business A purchases 5.5 million yen (tax-inclusive) annually from tax-exempt Business B:
| Period | Creditable Amount | Non-Creditable Amount (Additional Burden) |
|---|---|---|
| Current (through September 2026) | ¥400,000 (¥500,000 x 80%) | ¥100,000 |
| From October 2026 | ¥250,000 (¥500,000 x 50%) | ¥250,000 |
| From October 2029 | ¥0 | ¥500,000 |
The additional burden increases from ¥100,000 to ¥250,000 annually, making the practical question whether taxable businesses can absorb this increased cost.

To ease the burden on tax-exempt businesses that converted to taxable status for invoice issuance, the 20% Special Rule (a transitional tax credit measure for small-scale businesses) was established (Article 51-2 of the Supplementary Provisions of the 2016 Amendment Act).
Under this rule, the tax payable is reduced to 20% of the output tax amount. This is often more favorable than calculation under the simplified taxation system (Article 37 of the Consumption Tax Act), and many small-scale businesses have utilized it.
However, the 20% Special Rule expires with the taxable period that includes September 30, 2026. For sole proprietors with a December fiscal year-end, the 2026 fiscal year will be the last year of applicability.
Options After the 20% Special Rule Expires
| Option | Overview | Filing Required |
|---|---|---|
| Standard taxation | Actual input tax credited. Requires preservation of books and invoices | None (default) |
| Simplified taxation | Calculated using deemed purchase ratios (40-90% by industry) | Filing under Article 37 of the Consumption Tax Act required (by the day before the start of the applicable taxable period) |
Businesses that have been using the 20% Special Rule must decide during 2026 whether to file for simplified taxation or transition to standard taxation. Missing the filing deadline results in automatic application of standard taxation, significantly increasing bookkeeping requirements.
Impact on Freelancers and Sole Proprietors
For freelancers and sole proprietors, the second year of the invoice system represents a turning point.
Challenges for Registered Businesses
- Choosing a consumption tax calculation method after the 20% Special Rule expires (simplified vs. standard taxation)
- Permanent consumption tax filing obligations (annual deadline: end of March)
- Strict compliance with book preservation obligations under Article 58 of the Consumption Tax Act
Risks for Unregistered Businesses
- After October 2026, clients' credit rate drops to 50%, increasing the risk of losing business relationships
- Downward price pressure from prime contractors ("invoice discounting")
- Interaction with the Freelance Protection Act (Act on Ensuring Proper Transactions for Specified Entrusted Businesses)
Key Statutory Provisions
The core provisions of the invoice system are as follows:
| Provision | Content |
|---|---|
| Consumption Tax Act, Art. 57-2 | Registration system for qualified invoice issuers |
| Consumption Tax Act, Art. 57-3 | Obligations of qualified invoice issuers (issuance and preservation) |
| Consumption Tax Act, Art. 57-4 | Required items on qualified invoices |
| Consumption Tax Act, Art. 30 | Requirements for input tax credits |
| Consumption Tax Act, Art. 37 | Simplified taxation system |
| 2016 Amendment Act, Supp. Prov. Art. 51-2 | 20% Special Rule (transitional tax credit for small businesses) |
| 2016 Amendment Act, Supp. Prov. Art. 52-53 | Transitional measures for purchases from tax-exempt businesses |
Upcoming Schedule and Practical Responses
| Date | Event |
|---|---|
| September 30, 2026 | 20% Special Rule expires (sole proprietors: 2026 fiscal year is the last applicable year) |
| October 1, 2026 | Transitional credit rate reduced from 80% to 50% |
| December 31, 2026 | Effective deadline for simplified taxation filing (for application starting 2027) |
| September 30, 2029 | Complete expiration of transitional measures (credit for tax-exempt purchases drops to 0%) |
Businesses should consider the following actions heading into the second half of 2026:
- Reassess registration necessity — Evaluate comprehensively based on client relationships, revenue scale, and administrative burden
- Prepare simplified taxation filing — Decide on the taxation method early after the 20% Special Rule ends
- Review transaction terms — Prepare for price negotiations in light of the transitional measure reduction
- Confirm accounting system readiness — Ensure invoice-compliant bookkeeping and filing capabilities are in place
