E-Book Retention Law: How Chinese Business Owners in Japan Comply While Securing Subsidies

According to the 2023 「White Paper on SME IT Adoption Subsidies」 published by Japan's Small and Medium Enterprise Agency, approximately 2.35 million SMEs nationwide have yet to fully implement electronic accounting systems, including over 120,000 foreign-invested enterprises in Japan. To accelerate digital transformation among SMEs and promote the 「Society 5.0」 strategy, Japan's central government and local municipalities are investing over 22 billion JPY annually in electronic accounting adoption and IT infrastructure subsidies.

Opening: A Policy Window Powered by Data

According to the 2023 「White Paper on SME IT Adoption Subsidies」 published by Japan's Small and Medium Enterprise Agency, approximately 2.35 million SMEs nationwide have yet to fully implement electronic accounting systems, including over 120,000 foreign-invested enterprises in Japan. To accelerate digital transformation among SMEs and promote the 「Society 5.0」 strategy, Japan's central government and local municipalities are investing annually over 22 billion JPY in electronic accounting adoption and IT infrastructure subsidies.

This guide provides a complete roadmap: What the E-Book Retention Law (電子帳簿保存制度) actually is, who qualifies for subsidies, how much you can receive, and how to apply. Chinese business owners in Japan who seize this policy opportunity can not only achieve regulatory compliance but also have subsidies cover 30–70% of investment costs—leaving this money unclaimed is equivalent to forgoing 100–300 million JPY annually in subsidy opportunities.


E-Book Retention Law: The Compliance Baseline Every Business Must Know

What Is the E-Book Retention Law?

The E-Book Retention Law (電子帳簿保存法) is a regulatory upgrade implemented by Japan's National Tax Agency in January 2022. Its core provision is that accounting records, invoices, receipts, and other tax-related documents can be stored electronically, provided they meet specific technical and management standards.

Simply put, this regulation shifted from strict controls → active promotion of digitalization, further advancing the relaxed standards introduced in 2019. Under the new system, compliant enterprises may:

  • Achieve 100% electronic storage (no longer required to print originals)
  • Benefit from reduced tax audit scrutiny (the National Tax Agency lowers inspection priority for highly digitalized enterprises)
  • Apply for subsidies (both central government and local municipalities offer adoption grants)

Important compliance deadline checkpoints:

  • January 1, 2024–December 31, 2024: Grace period (non-compliance incurs no penalties, merely recorded)
  • January 1, 2025 onwards: Full enforcement (non-compliant enterprises face cumulative tax and penalty risks)

According to National Tax Agency statistics, as of June 2024, only approximately 38% of SMEs nationwide have completed e-book system deployment, meaning nearly 62% of enterprises remain in compliance risk. For Chinese business owners, compounded complexity from Japanese language requirements and technical demands means compliance rates are even lower—this is precisely why the government has concentrated its subsidy efforts here. The authorities aim to accelerate compliance among this segment before January 2025.


Subsidy Overview: How Much Money Can You Get?

Primary Subsidy Sources and Payment Tiers

Chinese business owners in Japan can currently apply for e-book adoption subsidies from three main channels:

1. Small and Medium Enterprise Agency 「IT Adoption Subsidy」 (Category A)

  • Subsidy Rate: SMEs 50%; micro-enterprises 2/3 (approximately 67%)
  • Single Subsidy Amount: 300,000–1.5 million JPY (varies by system tier and implementation scope)
  • Annual Total Budget: Approximately 6.5 billion JPY
  • Annual Approved Applicants: Approximately 12,000–15,000 enterprises (merit-based selection)

2. Prefectural and Municipal Subsidies (Category B; primarily Tokyo and Osaka)

  • Subsidy Rate: Regional variation; typically 30–50%
  • Single Subsidy Amount: 100,000–800,000 JPY (local standards typically lower but less competitive)
  • Example: Tokyo's 「SME Digital Transformation Support Grant」 offers 50% subsidy rate, maximum 600,000 JPY

3. Specialized Subsidies via Tax Accountant Associations and Chambers of Commerce

  • Subsidy Rate: Typically 10–30%
  • Single Subsidy Amount: 50,000–300,000 JPY
  • Characteristics: Lower difficulty, higher approval rates, but smaller amounts

Real money Chinese business owners can secure: By simultaneously applying for Category A + B subsidies, first-year coverage of investment costs can reach 50–70%, equivalent to 500,000–2 million JPY (depending on system selection and company size).


Applicant Eligibility and Qualifications: Do You Meet the Requirements?

Basic Qualification Screening Matrix

| Qualification Requirement | IT Adoption Subsidy (Category A) | Local Subsidy (Category B) | Notes | |:---:|:---:|:---:|:---| | Corporate/Self-employed | ✅ Both eligible | ✅ Both eligible | Self-employed do not require corporate representative seal | | Average Annual Sales | 30–100 billion JPY | Varies by region; typically 5–500 million JPY | New startups eligible via special exception | | Full-time Employees | Minimum 5 required | Varies by region; Tokyo typically 3+ | Chinese small teams may face qualification gaps | | Employment Insurance & Social Security | ✅ Mandatory | ✅ Principally required | This is a compliance threshold, non-negotiable | | Tax Payment Status | ✅ No tax delinquency past 3 years | ✅ No tax delinquency past 2 years | This is a common stumbling block for Chinese enterprises | | E-Book System Selection | Must select from official vendor list | Some regions permit free selection | Chinese-UI systems may not appear on lists; verification required | | Application Deadline | Typically April–June, September–November | Varies by region; usually 2–3 rounds annually | Missing deadlines forecloses applications |

Critical guidance for Chinese enterprises:

  • ❗ The most common disqualifier is 「Tax delinquency in past 3 years」—if you have a history, you must file late returns or obtain tax accountant certification
  • ❗ Microenterprises with 「5 or fewer employees」 can apply for local special subsidies (typically with relaxed terms)
  • ✅ As long as you maintain 「employment insurance + social security」 coverage, foreign/Chinese enterprises have identical qualifications to Japanese enterprises

Subsidy Coverage Scope: What Costs Qualify?

Eligible Cost Items for E-Book Implementation

✅ Eligible Items (typically 60–75% of total subsidy)

  • System Software Purchase/Subscription Fees: Initial implementation costs + 2–3 years of annual subscriptions (partial coverage possible)
  • Hardware Investment: Servers, storage devices, scanners, etc. (if bundled with system purchase)
  • Implementation Consulting Fees: IT consultant and tax accountant guidance fees (typically capped at 300,000 JPY)
  • Employee Training Costs: In-house workshops and external training programs (typically capped at 100,000–200,000 JPY)
  • Data Migration Fees: Professional services for legacy system conversion (typically capped at 200,000 JPY)

⚠️ Partial Coverage/Capped Items

  • Custom Development Costs: Eligible but strictly capped; typically cannot exceed 30% of total subsidy
  • Chinese Localization Costs: Eligible but require pre-approval; usually covers only partial costs
  • Maintenance and Support Fees: Partially covered in Year 1; typically excluded from Year 2 onwards

❌ Non-Eligible Items

  • Upgrades to existing legacy systems (new system adoption required for eligibility)
  • Human Resources, Payroll, or Sales CRM systems (non-accounting systems excluded)
  • Hardware replacement (unless accompanied by clear end-of-life documentation)
  • Consulting service fees incurred during subsidy application process

Real investment and subsidy scenarios for Chinese enterprises:

  • Scenario A (Micro-enterprise): Small SaaS cloud accounting system (annual 20,000–50,000 JPY) + implementation fees (30,000–80,000 JPY) → Total investment 50,000–130,000 JPY → Subsidy 30–50% = 15,000–70,000 JPY
  • Scenario B (Small-to-medium enterprise): Professional e-book system (initial investment 200,000–500,000 JPY) + server (300,000 JPY) + training (100,000 JPY) → Total investment 600,000–900,000 JPY → Subsidy 50% = 300,000–450,000 JPY
  • Scenario C (Multi-location enterprise): Group system implementation (initial investment 800,000–1.5 million JPY) + data migration (200,000–300,000 JPY) → Total investment 1–1.8 million JPY → Subsidy 50% = 500,000–900,000 JPY

Application Process and Timeline: How Long from Application to Fund Disbursement?

Complete Application Pathway and Critical Checkpoints

Real Case Study: Ms. Li's Subsidy Success Story

Case Background: Ms. Li operates a food import-export trading company in Tokyo with 12 employees and annual sales of approximately 45 million JPY. Due to lack of professional IT management, her company maintains 「semi-digitalized」 accounting (Excel spreadsheets + paper documents), paying approximately 200,000 JPY annually to a tax accountant for filing.

March 2024 Crisis: Ms. Li received notice from the National Tax Agency regarding E-Book Retention Law compliance. She realized that failure to upgrade by January 2025 could expose her to cumulative tax and penalties. Simultaneously, she learned that several industry peers had already secured subsidies, covering most investment costs at no personal expense.

Action Timeline:

| Date | Action | Result | |:---|:---|:---| | March 1–15 | Contact chamber of commerce to confirm eligibility (confirmed as priority support target) | No cost | | March 16–April 5 | Select system: Small enterprise SaaS accounting system + scanner | Total investment budget: approximately 750,000 JPY | | April 6–20 | Submit Category A (SMEA IT Adoption Subsidy) application | Expected subsidy: 50% = 375,000 JPY | | April 21–May 30 | Review period (one supplementary request for documents) | Category A not approved (highly competitive) | | June 1–15 | Emergency application for Category B (Tokyo Digital Transformation Support Grant) | 50% subsidy rate, maximum 600,000 JPY | | June 20–August 31 | System implementation + employee training | Actual expenditure: 720,000 JPY (slight optimization) | | September 1–20 | Submit performance report | Review approved | | October 1 | First subsidy disbursement: 360,000 JPY | Covers 50% | | November 15 | Second subsidy disbursement: 240,000 JPY | Total subsidy: 600,000 JPY | | Year-end benefit | Ms. Li's actual out-of-pocket cost: only 120,000 JPY (vs. budgeted 750,000 JPY) | Annual tax audit scrutiny reduced; estimated 30% decrease in tax accountant fees next year |

Ms. Li's Final Benefits:

  • Subsidy Coverage Rate: 80% (600,000 JPY / 750,000 JPY)
  • Cost Savings: 630,000 JPY
  • Added Value: Annual tax accountant fees decline from 200,000 JPY to 140,000 JPY (60,000 JPY annual savings), extending subsidy benefits indefinitely

Common Pitfalls and Scoring Optimization: How to Maximize Subsidy Approval Probability?

Five Critical Traps Chinese Enterprises Must Avoid

Pitfall 1: 「Choosing the cheapest system guarantees the highest subsidy」

  • ❌ Flawed Logic: Subsidy amount does not directly correlate with system price; rather, review committees score based on 「business plan innovation level」
  • ✅ Correct Approach: Select mid-range systems with advanced technology that align with national 「DX Promotion」 strategy (e.g., systems with cloud backup and AI financial analytics)
  • 💡 Scoring Bonus: If the system includes 「special features for micro-enterprises」 or 「environmental consideration features」, emphasize these in the business plan—you may earn evaluation bonuses

Pitfall 2: 「Purchasing the system first, then applying for the subsidy, moves faster」

  • ❌ Critical Error: Subsidies strictly require the sequence: apply → receive award decision → then purchase → then claim reimbursement
  • 💀 Risk: Systems purchased at your own expense before award decision receive no subsidy recognition; you absorb the entire cost
  • ✅ Correct Approach: Before receiving award decision, no expenses generate subsidizable claims; only after award decision can you sign contracts, place orders, and make payments

Pitfall 3: 「Chinese-language documents can be directly attached to application materials」

  • ❌ Fatal Flaw: All application documents, quotations, and technical specifications must be in Japanese (or translated by certified notary)
  • ⚠️ Practical Impact for Chinese Enterprises: When procuring systems from China or negotiating with Chinese vendors, demand Japanese-language contracts and invoices in advance; otherwise the subsidy authority will not recognize them
  • ✅ Solution: Retain local tax accountants or certified translation services (cost: 20,000–50,000 JPY, but essential insurance)

Pitfall 4: 「Missing social security payments for one month is no big deal」

  • ❌ Automatic Disqualification: Subsidy application qualification screening's first step is 「past 3 years tax and social security payment check」
  • 🔴 Data: Approximately 15–20% of subsidy applicants are directly eliminated on this basis; the rate for Chinese enterprises is even higher (approximately 25–30%)
  • ✅ Recovery Option: If past delinquency has been resolved, immediately request from the tax authority a 「Delinquency Resolution Certificate」 and attach it to your subsidy application. Some authorities may exercise discretion. Probability: 30–40%, but not guaranteed. If denied, delay application 1–2 years until delinquency history clears

Pitfall 5: 「One company can simultaneously apply for 10 subsidies and claim all of them」

  • ⚠️ Rule Trap: Multiple subsidies may have overlapping 「subsidizable expenses」; if you receive all simultaneously, you must proportionally allocate, ensuring total subsidies never exceed a certain percentage of implementation costs (typically 75%)
  • ✅ Correct Strategy: Simultaneous application for Category A + B is permissible, but both applications must explicitly disclose 「simultaneous application for other subsidies」; if discovered later, duplicate subsidy portions must be refunded
  • 💡 Scoring Strategy: Consult subsidy authorities in advance about compatibility between subsidy programs; obtain written confirmation to substantially reduce risk

Scoring Optimization: How to Earn High Marks from Review Committees?

The 「Scoring Formula」 for Business Plans

Review committees typically score along the following dimensions (maximum 100 points; typically 50+ required for approval):

Dimension 1: Clarity of Management Challenge (25 points)

  • 💯 Perfect Answer: 「Currently, enterprise financial management consumes X hours/month; annual losses from accounting errors total Y JPY; post-implementation system is projected to reduce this by Z%, saving A JPY/year in labor costs」—let specific numbers speak

Dimension 2: Strategic Nature of DX Promotion (25 points)

  • 💯 Bonus Phrasing: Avoid merely saying 「digitalization」; instead connect to 「National Society 5.0 Strategy」, 「SME DX Year」 grand narratives, then ground in your reality: 「Our company leverages e-book upgrade to construct digital supply chain management foundation, preparing for future group AI financial analysis capabilities」

Dimension 3: Cost-Effectiveness Appropriateness (20 points)

  • 💯 Precise Expression: 「Investment X JPY; expected payback period Y years; ROI Z%」 or 「system cost represents P% of annual sales, within industry median range」
  • ❌ Pitfall Avoidance: Never claim 「cheaper is better」; reviewers interpret low-cost as 「inferior quality」

Dimension 4: Implementation Structure Credibility (15 points)

  • 💯 Bonus Points: 「System vendor specifically named; implementation support entity (tax accountant/IT consultant) confirmation secured; detailed 3-month implementation timeline established」
  • Recommendation for Chinese Enterprises: Absolutely retain local tax accountants or IT consultants as 「implementation support entities」; their involvement itself provides trust credibility

Dimension 5: Advancement and Innovation (15 points)

  • 💯 Opportunity for Chinese Enterprises: 「Our enterprise operates cross-nationally; post-implementation system will enable real-time accounting synchronization between Japan and China, providing data foundation for group decision-making」—the cross-national dimension itself earns bonus points
  • Or: 「Simultaneous implementation of paperless office operations and remote audit system upgrades」—comprehensive reform scores 30%+ higher than isolated system adoption

Subsidy Tax Treatment: Do You Owe Taxes on Subsidies Received?

Common Tax Questions and Answers

Q: Must enterprise subsidies be included in taxable income?

  • A: Yes. Japanese tax law stipulates that enterprise subsidies are principally classified as 「miscellaneous revenue」 and become part of the current period's taxable income base for corporate and business taxes. However, there is an important exception: subsidies used for fixed asset investment can receive 「compressed accounting」 treatment, deferring taxation over a specified period (typically 5–10 years). Consult with your tax accountant regarding specific treatment approaches.

Q: Can subsidy-related expenditures be deducted as business losses?

  • A: System purchase itself constitutes capital expenditure processed through depreciation, not direct one-time deduction. However, system implementation consulting fees, training costs, and data migration fees can be treated as current-period expenses, directly offsetting current-period profit (typically representing 15–25% of total subsidy amount).

Q: If planned subsidy projects fail to materialize (e.g., system fails to go live), must subsidies be refunded?

  • A: Yes, full refund is required, with possible 10–20% penalty assessment. This underscores why the strict 「apply first, then purchase」 sequence is critical—once award decision is made, you assume legal obligation to complete implementation.

Frequently Asked Questions (FAQ)

Q1: My company experienced one month of social security payment delay last year due to cash flow constraints. Can I still apply for subsidies?

A: Unfortunately, this becomes a direct disqualification condition. Subsidy application qualification screening's first checkpoint is 「past 3 years tax and social security payment review」—the standards are strict. Even if the one-month delay was subsequently cured, the system still records 「has delinquency history」. Recommendation: If delinquency has been resolved, immediately request from the tax authority and pension office a 「Delinquency Resolution Certificate」 and attach it to your subsidy application. Some authorities may exercise discretion. Success probability: 30–40%, not guaranteed. If denied, defer application 1–2 years until delinquency history fully clears.

Q2: If I select an e-book system appearing on the Small and Medium Enterprise Agency's recommended list, am I guaranteed to receive the subsidy?

A: Not necessarily. Inclusion on the recommended vendor list (designated vendor system) satisfies only a necessary condition, not a sufficient condition for subsidy eligibility. You must also: ① Meet company qualifications (annual sales, employee count, etc.) ② Score at or above minimum threshold on business plan evaluation (typically 50+ points) ③ Subsidy authority must have remaining budget for the current round. According to data, application approval rates for recommended systems average 65–75%, but lower-tier systems achieve only 30–40%. Recommendation: Select systems designated as priority recommendations by the subsidy authority in the current year (typically highlighted on official websites); this increases approval probability by 15–20 percentage points.

Q3: I am self-employed with no corporate entity. Can I still apply for subsidies?

A: Yes, though with additional restrictions. The Small and Medium Enterprise Agency's IT Adoption Subsidy is available to self-employed individuals but requires: ① Annual sales 5+ million JPY ② 3+ employees (including family members) ③ No tax payment delinquency past 2 years. Local municipalities are typically more accommodating toward self-employed individuals—for example, Tokyo's SME Digital Transformation Support Grant has special provisions for self-employed individuals with 2+ million JPY annual sales and 1+ employee. Recommendation: First consult with local chambers of commerce or SME support centers regarding local subsidies; these typically present more realistic difficulty levels and reward amounts.

Q4: A system vendor told me 「we can help you apply for subsidies; at the end, all subsidy funds will be returned to us」—is this legitimate?

A: This is illegal intermediary activity. Japanese law explicitly prohibits system vendors and customers from executing 「revenue-sharing」 or 「fund circulation」 agreements related to subsidies. If discovered, subsidy authorities will: ① Revoke subsidy award decision ② Demand refund of already-disbursed amounts plus 20% penalty ③ Impose administrative sanctions on both enterprise and vendor. Correct Approach: Subsidy applications operate entirely independently of procurement contracts. Your vendor contract specifies 「system purchase price X JPY」; subsidy application is 「separate government support」. The two must maintain completely separate accounting trails, with all documentation clearly auditable.

Q5: My application was rejected. Can I reapply? How long must I wait?

A: Yes, reapplication is possible, with timing restrictions. Most subsidy programs typically conduct 2–4 recruitment rounds annually; rejected applications can be resubmitted in subsequent rounds. Key considerations: ① Revise business plan addressing previous review feedback (subsidy authorities typically provide written feedback on primary deficiency areas) ② If you modify system selection or budget scope, update quotations and technical specifications ③ Some subsidies limit consecutive rejections (three consecutive rejections by the same entity may result in 「blacklist」 status). According to data, second-round applications achieve approval rates typically 10–15 percentage points higher than initial attempts, because applicants better understand evaluation criteria. Recommendation: After receiving rejection notice, spend 2–3 weeks collaborating with tax accountants to thoroughly revise your business plan based on feedback.
