Introduction
Japan’s financial and compliance landscape is undergoing a rapid digital transformation. With the Japanese government’s push toward 電子帳簿保存法 (E-Accounting Law, Electronic Book Storage Act) and e-Tax (Electronic Tax Filing System), businesses are required not only to digitize their financial records but also to ensure compliance with strict guidelines around archiving, retrieval, and auditability.
For Japanese enterprises—whether large corporations or growing SMEs—the challenge lies in managing this compliance while also streamlining business operations. This is where Microsoft Dynamics 365 Business Central plays a pivotal role. As an integrated ERP (Enterprise Resource Planning) platform, Business Central ensures that companies remain compliant with Japanese regulations while improving efficiency, visibility, and accuracy across finance and operations.
At Sysamic, a trusted Dynamics 365 Partner in Japan, we work closely with businesses to bridge the gap between regulatory compliance and digital transformation. Let’s explore how Business Central supports e-Tax and e-Accounting in Japan, and why this matters for forward-looking enterprises.
Why E-Tax and E-Accounting Matter
Japan’s e-Tax system is a government-driven initiative allowing companies to file corporate taxes, consumption tax (VAT), and income tax electronically. This reduces paper submissions, enhances efficiency, and allows the National Tax Agency (NTA) to streamline audits.
On the other hand, the 電子帳簿保存法 (Electronic Book Storage Act) defines how accounting records, invoices, and receipts must be stored digitally. Recent revisions to the law emphasize three critical elements:
Authenticity – Ensuring data integrity and preventing unauthorized modifications.
Accessibility – Making digital records easily retrievable for audits.
Traceability – Maintaining proper logs of approvals, changes, and submissions.
For Japanese businesses, the stakes are high. Non-compliance can mean penalties, delayed filings, or reputational risks. Yet, compliance alone isn’t enough—companies also need solutions that simplify processes and reduce manual overhead.
The Role of Dynamics 365 Business Central in Compliance
Dynamics 365 Business Central is designed to integrate compliance into day-to-day business processes. Rather than treating e-Tax and e-Accounting as standalone obligations, Business Central embeds compliance into financial workflows.
Here’s how:
Digital Record Management: Business Central supports secure document storage and integrates with workflow automation, ensuring invoices, receipts, and ledgers meet the Electronic Book Storage Act’s standards for authenticity and accessibility.
Tax Automation: With built-in tax calculation capabilities aligned with Japanese consumption tax rules, Business Central helps businesses minimize errors in VAT filings. Data is automatically structured for submission through the e-Tax system.
Audit-Ready Reporting: Business Central enables Japanese CFOs and controllers to generate standardized financial reports that align with both JGAAP (Japanese Generally Accepted Accounting Principles) and e-Tax requirements, simplifying audits and financial disclosures.
Integration with E-Invoice Mandates: With Japan’s growing adoption of electronic invoicing (in line with the インボイス制度 – Qualified Invoice System), Business Central ensures smooth integration between invoicing and accounting, reducing reconciliation gaps.
Business Value for Japanese Enterprises
While compliance is non-negotiable, the real advantage of Business Central lies in how it transforms compliance into business value:
Efficiency Gains: Automating tax filings and accounting processes reduces the administrative load on finance teams.
Transparency: Real-time visibility across transactions helps executives make faster, more informed decisions.
Scalability: Whether expanding globally or diversifying operations within Japan, Business Central scales with the business while staying compliant.
Risk Reduction: With secure digital storage and proper approval workflows, businesses reduce risks of tax disputes or audit failures.
