FAQ
When is Japan JCT due?+
Annual JCT returns are due by March 31 of the following fiscal year.
What is the qualified invoice system and how does it affect my filing?+
From October 2023, only qualified invoices (適格請求書) issued by registered businesses allow buyers to claim input tax credits. Your qualified invoice must include: your registered number (T-number), the applicable tax rate, and the tax amount. When filing, you must report all qualified invoices issued and received. The NTA provides an online tool to search for registered businesses by their T-number. If you issue incorrect invoices, your buyers may lose their tax credits.
Can I file my JCT return in English?+
No. All JCT returns must be filed in Japanese through the e-Tax system or by paper submission to your jurisdictional tax office. The return forms (Form 11 for regular taxpayers, Form 12 for simplified scheme) are only available in Japanese. If you are a foreign business without a Japanese entity, your tax representative must file on your behalf in Japanese. The NTA does not accept English-language returns or supporting documentation.
What happens if I miss the JCT filing deadline?+
Missing the JCT filing deadline triggers penalties: (1) non-filing penalty (無申告加算税): 15% of unpaid tax if you file late voluntarily, 20% if the NTA discovers it first; (2) underpayment penalty (過少申告加算税): 10% of the underpaid amount; (3) interest on late payment (延滞税): 2.4% per year for the first month, 14.6% per year thereafter. The NTA is generally strict about deadlines — extensions are rarely granted except in cases of natural disaster.
What is the difference between the standard taxation method and the simplified taxation method?+
Under the standard method, you calculate JCT due by subtracting input tax credits from output tax on sales. Under the simplified method (available for businesses with taxable sales of JPY 50 million or less in the base period), your input tax credit is calculated as a fixed percentage of your output tax based on your industry classification (e.g., 80% for wholesale/retail, 50% for manufacturing). The simplified method reduces compliance burden but may result in higher or lower tax depending on your actual input costs.
