About this app

*As a commemoration of the release, it is available for free for the time being. Please try it once.

In the tax law collection, you can analyze the wording of enforcement orders, enforcement regulations, and notifications that are essential for tax practice, and refer to related enforcement orders, enforcement regulations, and notifications based on the provisions of the law. Of course, it is also possible to access other laws and regulations listed in the tax law collection from each law, enforcement order, enforcement regulation, and notification.

[Feature 1: Minimize the effort of searching]
If you have decided on the desired article, you can display it immediately by specifying the number. In addition, if there is an enforcement order, enforcement regulation, or notification, we present a list of clauses that refer to those clauses, so that you can quickly access lower-level laws and regulations.

[Feature 2: Full text included]
In paper versions of the Six Laws, some articles are often omitted due to space limitations. The collection of tax laws and regulations includes all provisions without omitting them, including the lengthy Special Tax Measures Act. All data includes the latest version of the legal data provision system.

[Feature 3: No communication required]
In the app version, all the provisions are downloaded to the device, so no communication occurs. The latency is very low even when calling long clauses. In addition to displaying articles, you can also search for articles offline.

[Feature 4: Pursuing readability]
In addition to being able to adjust the font size and line spacing when reading articles, you can also switch between Mincho and Gothic fonts. You can customize it to make it easier to use, making it larger and wider if it is difficult to read small text, or smaller and narrower if you want to pack more information.

[About legal data included in this app]

----
From now on, we plan to update the laws and regulations to the latest information about once a month and add new features such as the following.

- Added references between laws and regulations
:Currently, only references to enforcement orders, enforcement regulations, and basic notices are included for each article, but references from laws will also be added.
- Addition of basic notifications
:If the number of users increases enough, the coverage area of ​​the notification will be expanded.
- Optimized for tablets
: Makes it possible to use the screen horizontally instead of vertically, taking advantage of the screen's width.
- Display of revised information
: Allows you to check what has been revised when laws and regulations are replaced.
- Display of old provisions
: If revised, the old provisions of the relevant provisions will also be displayed from the button.
- Display of new provisions before enforcement
: If an unenforced article is posted, the new article for that article can also be displayed from the button.
- Display of provisions after the replacement of reading provisions
: First of all, we will start with the usual rereading provisions, but we will also make it possible to display the rereading of the provisions from a button.
- Access to source
: In order to be able to confirm whether there are any discrepancies with official information, we will make it easy to navigate from articles and notices to the e-Gov law search or the relevant page of the National Tax Agency.
- Display of latest case law
: We are considering linking it with the collection of tax precedents on the court website.
