Mycat Inc. (Headquarters: Meguro-ku, Tokyo) is pleased to announce the addition of a notification check feature for freelancers and sole proprietors to its license and permit search service, "Kyoninka Navi" (https://kyoninka.xyz).

Overview of New Features

The freelancer notification check feature allows users to input information such as industry, business details, and revenue scale. AI then automatically determines and lists the necessary filings.

Supported filings include:

  • Notification of Opening a Business (Individual Business Opening Notification)
  • Application for Approval of Blue Return
  • Notifications related to the Invoice System (Registration Application for Qualified Invoice Issuers)
  • Notification of Commencement of Business (for Prefectural Tax Offices)
  • Industry-specific licenses and permits (e.g., restaurant business permits, construction business licenses)

Background of Development

According to a survey by the Cabinet Secretariat, the freelance population in Japan is approximately 4.62 million (Source: Cabinet Secretariat "Freelance Fact-Finding Survey"). When including side jobs and concurrent employment, the number of individuals conducting business activities is even higher.

However, few people grasp the full scope of necessary filings at the time of opening a business. The types of filings and procedures have become increasingly complex, particularly with the start of the Invoice System. Failure to file or delays in submission can lead to tax disadvantages, such as being unable to receive the benefits of the Blue Return.

Importance of Invoice System Compliance

Since the start of the Invoice System in October 2023, there has been an increase in cases where business partners request the issuance of qualified invoices. While registering as a qualified invoice issuer is optional, failing to register may affect business relationships, as partners may be unable to claim input tax credits.

Utilizing "Kyoninka Navi"

The notification check feature allows users to confirm the submission destination, deadlines, and required documents for each filing in a checklist format. It displays alerts for filings with approaching deadlines to prevent procedural omissions.

※ This service does not constitute agency work under the Certified Public Tax Accountant Act or the Certified Administrative Procedures Legal Specialist Act. Please consult with professionals such as tax accountants or administrative scriveners for formal filings.
