Overview

Taxable corporations whose prior fiscal year's final consumption tax (national tax portion) exceeded ¥480,000 must file interim returns. For annual interim filing, the filing window is within 2 months after the end of the first 6 months of the fiscal year. You can choose between the prior-year method or the provisional settlement method (仮決算方式).

Schedule

Applicability

• Applicable to: Kabushiki Kaisha (KK), Godo Kaisha (GK)
• Requires consumption tax applicability

Interim returns are required only for taxable business operators whose prior fiscal year's final consumption tax amount (national tax portion, excluding local consumption tax) exceeded ¥480,000. If the prior fiscal year was less than 12 months (e.g., the first fiscal year of a newly established corporation), the amount is annualized for this determination. If the prior fiscal year's final consumption tax amount was ¥480,000 or less, or if you are an exempt business operator (免税事業者), interim returns are not required. Even when interim filing is not mandatory, voluntary interim returns may be filed. This can be useful when a provisional settlement would result in a refund.

Filing Methods

Additional Details

The number of interim filings depends on the prior fiscal year's final consumption tax amount (national tax portion). Once per year (over ¥480,000 up to ¥4 million), three times per year (over ¥4 million up to ¥48 million), or eleven times per year (over ¥48 million). This entry shows the deadline for the annual interim filing. There are two calculation methods. (1) Prior-year method (前年実績方式): Calculate based on the prior year's final tax amount (most common). For annual filing, pay 6/12 of the prior year amount; for three times per year, pay 3/12 each time; for eleven times per year, pay 1/12 each month. (2) Provisional settlement method (仮決算方式): Perform a provisional settlement for the interim period and calculate actual taxable base and tax amount. This is useful when business performance has declined and the prior-year method would impose an excessive burden. If you fail to file an interim return by the deadline, it will be deemed filed under the prior-year method (みなし申告), and you remain liable for that amount.

Penalties for Non-Compliance

If an interim return is not filed by the deadline, it is deemed filed under the prior-year method (みなし申告). Therefore, a failure-to-file penalty is generally not imposed for non-filing of the interim return. However, if the deemed interim tax is not paid by the deadline, delinquent tax (延滞税) applies: • 2.4%/year for the first 2 months, 8.7%/year thereafter (Reiwa 7 special rates).
