Japan: Japan NTA Issues Compact Accounting Software Bookkeeping Guide

On 2 October 2026, the National Tax Agency (NTA) released new guidance for the Accounting Software Compact Type under the external outsourcing bookkeeping guidance program. This initiative targets small and medium-sized enterprises (SMEs) that outsource bookkeeping to tax accountants or certified public accountants using cloud-based or simplified accounting software. The guidance operationalizes the provisions of the Certified Public Tax Accountant Act and the Income Tax Act, establishing a standardized framework for the scope of guidance, data verification procedures, and the responsibilities of the outsourcing provider versus the taxpayer.

Key Takeaways

  • Simplified Guidance Framework: The Compact Type reduces the scope of mandatory checks compared to the standard guidance, focusing on critical error areas such as sales recording timing, expense classification, and consumption tax categorization, lowering professional fees for SMEs.
  • Digital Data Exchange Standards: Mandates the use of standardized data formats for transferring journal data between taxpayers and tax professionals, facilitating seamless integration with the NTA e-Tax system.
  • Clear Liability Allocation: Explicitly defines that the taxpayer retains ultimate responsibility for the accuracy of tax returns, while the tax professional is liable for guidance negligence, reinforcing the need for robust engagement letters.
