Deadline of corporate tax filings

Corporations must file a final tax return for such as corporate tax, corporate inhabitant tax and enterprise tax on their income within two months from the day following the last day of each taxable year. However, an extension of the deadline for filing a final tax return may be requested, with approval from the director of the taxation office, when a corporation is unable to file a final tax return because the accounting auditor has not completed the audit or because accounts remain unsettled for other unavoidable reasons. The income and tax amounts to be entered in the final tax return must be calculated in accordance with the statement of accounts approved by the general meeting of stockholders. The calculated tax must also be paid within this period. The payment deadline will not be extended even if the deadline for filing of a final tax return is extended as described above. Therefore, interest tax and overdue tax for the extended period are imposed (as deductible expenses) if the tax payment is made during the extended period. Any interim payment made in advance on the amount of tax owed shall be deducted from the total amount to be paid. Corporations whose taxable years exceed six months must file an interim return, within two months from the day marking the end of the first six months of the taxable year, an interim tax return for the period starting on the first day of that taxable year and ending on the day six months thence, and must pay the interim amount of tax owed (excluding instances where the amount of tax calculated using the prescribed formula does not exceed a certain amount).
