Welcome to Kabu Tax. These Terms of Service ("Terms") govern your access to and use of the Kabu Tax calculation tool and services. By accessing or using our Service, you agree to be bound by these Terms.
Kabu Tax is a calculation utility designed to assist users in preparing Japanese tax filings. The Service processes user-uploaded CSV files from United States brokerage accounts to generate JPY cost basis transactions. The Service implements calculation logic based on rules published by the National Tax Agency (NTA) of Japan, specifically regarding moving average cost basis and USD to JPY currency conversion.
Please read this section carefully.
Kabu Tax is strictly a software calculation tool. We are not a tax accounting firm, and we do not provide tax advice, financial advice, or legal advice.
While we strive to implement NTA rules accurately, the final responsibility for tax filing decisions rests solely with the user. You acknowledge that tax laws are subject to change and interpretation.
We strongly recommend consulting with a qualified tax professional (Zeirishi) regarding your specific tax situation and filing decisions.
Kabu Tax is not responsible for any errors, omissions, or penalties resulting from your tax filings or the use of reports generated by this Service.
To use the Service effectively and accurately, you agree to:
Provide complete, accurate, and unmodified CSV data from your brokerage.
Independently verify the accuracy of all calculations and reports generated by the Service prior to filing your taxes.
Maintain your own permanent records of your trading history and tax documents; Kabu Tax should not be used as a primary data backup solution.
All payments are securely processed via Stripe. We do not store your credit card information.
Due to the digital nature of the content, all sales are final. No refunds will be issued once the PDF report has been downloaded or delivered.
The Service is provided on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, whether express or implied.
To the maximum extent permitted by law, Kabu Tax shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues.
In no event shall our aggregate liability for any claim exceed the total amount you paid to the Service for the specific report giving rise to the claim.
We reserve the right to modify these Terms at any time. If we make material changes, we will notify you by updating the "Last Updated" date at the top of this page. Your continued use of the Service after any such changes constitutes your acceptance of the new Terms.
These Terms are governed by the laws of Japan.
