Taxnap

What Taxnap does

Taxnap is a Tokyo-based mobile tax filing application targeting individual freelancers, sole proprietors, and side-business earners in Japan, founded in November 2022 (originally as TxTo, rebranded to Taxnap in July 2025) by CEO Yuta Tanaka. The product unifies daily expense capture through tax return submission on a smartphone, integrating with My Number card for direct e-Tax submission and connecting to Japanese bank accounts for automatic transaction ingestion. Its proprietary AI-powered expense categorization engine — supervised by licensed tax accountants and a CPA YouTuber partner (ヒロ税理士 / 田中宏明) — automatically classifies whether expenditures are business or personal and assigns accounting categories at a claimed throughput of 1,000 items in 3 seconds, with a swipe-based interface designed for users without accounting knowledge.

The platform offers three commercial tiers: a free service for deduction-only and miscellaneous income filers, a monthly subscription ('Taxnap for business income') covering full sole-proprietor blue return filing with the Tax Investigation Risk Check feature, and a premium one-time Receipt Outsourcing Plan (¥49,760 campaign / ¥59,760 regular) where users mail physical receipts for company-handled categorization. Adjacent modules have been progressively added — screenshot-based expense categorization (December 2024), invoice/estimate generation (March 2025), business opening notification filing (July 2025), and real estate income support (December 2025) — positioning the app as a broader freelancer back-office suite.

Taxnap employs a product-led growth model: self-serve mobile downloads from the iOS App Store and Google Play, with heavy top-of-funnel investment via a January 2026 national TV CM campaign featuring actress 多部未華子 and partnerships with CPA YouTuber channels. In January 2026 the company closed a ¥1.3 billion Series A led by WiL (World Innovation Lab) with Mizuho Bank debt financing, bringing cumulative funding to ~¥1.6 billion (~$16M USD); cumulative tax returns supported exceed 20,000 and registered members grew 10x year-over-year. The company operates from Ebisu, Tokyo, with 1-10 employees.

Core offering

Taxnap develops and operates a mobile tax filing application for Japanese freelancers, sole proprietors, and side-business earners. The app uses AI-powered automatic expense categorization supervised by licensed tax accountants, integrates with the My Number card for direct government submission via e-Tax, and supports blue return (青色申告) filings. The platform is offered as a freemium product with a free tier for deduction-only filers, a premium subscription for business income filers, and a hybrid Receipt Outsourcing Plan that combines postal receipt intake with app-based processing.

Product overview

Taxnap operates as a unified mobile tax filing platform targeting individual workers in Japan — freelancers, sole proprietors, part-time workers with side businesses, and rental property owners. The product portfolio consists of two main app tiers: the core paid '事業所得者向け' (Business Income) app for comprehensive tax filing with AI-powered automatic categorization, and the free '控除のみ・雑所得向け' (Deductions Only) app for simpler cases. These core apps are supplemented by the premium 'レシート丸投げプラン' (Receipt Outsourcing Plan) for users preferring to mail physical receipts. Additional functional modules expand the platform's scope: invoice/estimate generation, screenshot categorization, real estate income support, and business opening notification filing. The entire suite is unified under a single brand with a mobile-first approach, smartphone My Number card integration, and shared AI-powered categorization technology across products.
