## Reasons Why Taxnap Is Chosen

### App Design Specialized for Sole Proprietors and Smartphone-Only Completion

With Taxnap, daily expense processing to tax return submission can be completed entirely on a smartphone. If you have a My Number Card, you can complete your tax return without needing to visit a tax office or mail documents.
Traditional accounting software is generally designed for PC operation and offers multi-functional features to meet a wide range of needs.

Taxnap was designed from scratch to specialize in "sole proprietors" and "smartphone-only completion," offering intuitive operations that eliminate complex functions, allowing users to smoothly complete everything from expense entry to tax return submission without getting lost.

### Speed of Expense Processing

According to a survey conducted by an external organization in November 2025, it was revealed that when using Taxnap, the number of expense processing cases in the same amount of time was approximately 4 times that of other accounting software (approximately 18 times compared to manual entry, and approximately 40 times compared to Excel).

The secret to its speed is the "Marunage Shiwaike" (throw-in sorting) function, which completes 1,000 expense processes in as little as 3 seconds.
By automatically judging based on past trends and data from the same occupation, the app can significantly reduce the time spent on daily tasks.

## User Voices

Users who have actually used Taxnap have provided the following reviews:

- "Tax filing used to take me 3 days, but now it's shortened to 1.5 hours!"
- "This was the easiest tax filing I've ever done! Input was easier than other apps, and I could even submit it within the app."

Many comments praise the reduction of the tax filing burden and the ease of completing it solely on a smartphone.

## Summary

Taxnap recorded the #1 position in the App Store's tax filing app ranking for 29 days during the 2026 tax filing period (February 16 to March 16, 2026).
As exemplified by comments like "tasks that used to take 3 days were shortened to 1.5 hours," many users feel the burden of filing has been reduced.

Taxnap significantly reduces the time required for tax filing, supporting an environment where freelancers and sole proprietors can concentrate more on their main business. We will continue to evolve to empower individuals who work independently.

## What is Taxnap?

Taxnap is a smartphone app for sole proprietors and side-job holders, based on the concept of "tax filing without effort." It allows users to complete all necessary tasks for tax filing, from daily sorting to creating and submitting tax returns, entirely through a single smartphone app.

Its biggest feature is the "Marunage Shiwaike" function, which completes 1,000 expense processes in 3 seconds. By linking financial institutions to the app, it accurately determines whether an "expenditure" is for business or private use and which account title is appropriate, greatly reducing the time and stress involved in preparing for tax filing.

Additionally, the "Tax Audit Risk Check" function, supervised by tax accountants, assesses tax audit risk based on input content and journal data, comparing it with trends in the same occupation. It is equipped with features that remove pre-submission anxiety and support confident tax filing.
