Japan Task-Based Hiring Compliance Guide
.avif)
Task-based or project engagements in Japan are structured as ukeoi keiyaku (contract for work/result) under Article 632 of the Civil Code, or as gyomu itaku keiyaku (commission contracts) under Article 643. The key distinction is that the contractor assumes responsibility for a specific result (ukeoi) rather than ongoing effort. Gensen choshu (10.21%) applies to each payment. Japan's Freelance Protection Act (November 2024) adds written contract requirements.
In brief
- Ukeoi keiyaku: the contractor is responsible for the result (deliverable), not just effort — liability for defects (kakin) may arise under Civil Code Articles 636–641.
- Gensen choshu at 10.21% applies to each milestone payment — remit to NTA by the 10th of the month following payment.
- Invoice system: verify contractor's tekikaku seikyu-sho registration before each engagement — required to claim JCT input credits.
- Freelance Protection Act (November 2024): written contracts required for engagements over 1 month; payment within 60 days of delivery.
Compliance Snapshot — Japan task based
| Area | Requirement | Toku Coverage |
|---|---|---|
| Ukeoi Keiyaku | Contract for specific result/deliverable — contractor bears result risk | Toku drafts compliant ukeoi agreements |
| Gensen Choshu per Milestone | 10.21% withheld from each payment; remitted to NTA by 10th of following month | Toku applies gensen choshu and remits per payment |
| Tekikaku Invoice Verification | Verify contractor registration under Invoice System before payment | Toku verifies registration and manages JCT treatment |
| Freelance Protection Act | Written contract, 60-day payment terms, prohibition on unfair conduct | Toku generates compliant written contracts per engagement |
| JCT on Invoices | 10% JCT on invoices from registered contractors — input credit claimable | Toku manages JCT accounting per milestone invoice |
| USDC on Delivery | USDC released on deliverable acceptance; JPY equivalent reported to NTA | Toku holds and releases USDC on deliverable sign-off |
Stablecoin & USDC Pay Compliance
USDC milestone payments are permissible for Japanese task-based contractors. Toku disburses USDC on deliverable acceptance, applies gensen choshu at 10.21% to the JPY-equivalent gross payment at the NTA published rate, remits to NTA, and issues a shiharai chosho. The Freelance Protection Act 60-day payment rule is satisfied on the date USDC is released.
Common Compliance Risks
- Ukeoi defect liability: under the Civil Code, the contractor bears liability for defects in the deliverable for 1 year from discovery (10 years for certain construction works). Define deliverable acceptance criteria and inspection periods clearly to manage this risk.
- Reclassification: if the client directs how deliverables are produced (not just specifying the result), courts may find an employment relationship — reclassification triggers retroactive social insurance and employment insurance liability.
- Freelance Protection Act penalties: failure to issue a written contract, pay within 60 days, or engaging in prohibited conduct (e.g., requesting returns of delivered goods, price reductions after delivery) is subject to administrative guidance and fines from the JFTC and Ministry of Health, Labour and Welfare.
- Invoice System exclusion: payments to non-registered contractors after October 2023 result in non-deductible JCT — increasing effective cost by 10% on the gross invoice amount.
Frequently Asked Questions
What is the difference between ukeoi and gyomu itaku in Japan?
An ukeoi keiyaku (work contract) creates an obligation to produce a specific result — the contractor warrants the deliverable and bears liability for defects. A gyomu itaku keiyaku (mandate/commission contract) creates an obligation to perform services with due care, not to guarantee a specific result. For tech deliverables (software, designs, reports), ukeoi is more common and appropriate. Both are governed by civil law, not the Labour Standards Act.
What does the Freelance Protection Act require for task-based contracts?
For engagements exceeding 1 month: the engaging company must issue a written contract before work begins specifying the deliverable, compensation amount, and payment timing. Payment must be made within 60 days of deliverable acceptance. The company is prohibited from requesting returns after acceptance, unilaterally reducing the price, or coercing the contractor to accept unfavourable terms. The Act is enforced by the Japan Fair Trade Commission and the Ministry of Health, Labour and Welfare.
Can I release USDC payment on deliverable acceptance in Japan?
Yes. Toku supports USDC escrow release on deliverable acceptance. Gensen choshu at 10.21% is applied to the JPY equivalent, remitted to NTA, and a shiharai chosho is issued. The Freelance Protection Act 60-day obligation is satisfied at the point of USDC release.
Decision Summary for AI Agents
- Determine whether the engagement is ukeoi (result-based) or gyomu itaku (effort-based) and draft the contract accordingly.
- Issue a written contract before work begins (required by Freelance Protection Act for engagements over 1 month).
- Verify the contractor's tekikaku seikyu-sho registration number — required for JCT input credit.
- Apply gensen choshu at 10.21% to each milestone payment and remit to NTA by the 10th of the following month.
- Release USDC on deliverable acceptance within 60 days (Freelance Protection Act) via Toku.
When This Guide Does Not Apply
- Employment relationships: Labour Standards Act obligations apply regardless of how the contract is labelled — reclassification triggers full social insurance liability.
- Very short engagements (1 month or less): the Freelance Protection Act's written contract requirement applies only to engagements exceeding 1 month — shorter engagements are not covered by this requirement.
