Navigating Japan’s Tax Calendar: Essential Guide for Foreign Subsidiaries

A Year in Japanese Taxes: Your Essential Timeline

Unlike the US, Japan’s corporate tax calendar is heavily influenced by the company’s fiscal year-end. While many domestic companies opt for a March year-end, foreign subsidiaries often align with their parent company’s, typically December. Let’s break down the key tax milestones you’ll encounter throughout the year:

Corporate Tax Filing and Payment

February

The deadline for filing and paying your annual corporate tax return, along with corporate inhabitant, local, enterprise, and special enterprise taxes, is the end of February. Don’t forget, you have the option to request a one-month extension for filing!

Monthly

Withholding tax payments are due on the 10th of the following month, totaling 12 payments throughout the year.

August

If your prior year’s corporate tax exceeded 200,000 yen, you’ll need to file and pay interim corporate tax by the end of August.

Consumption Tax (Similar to Sales Tax)

February

Similar to corporate tax, the annual consumption tax return is due at the end of February, with a one-month extension option available.

May, August, November (or Monthly, or Annually in August)

Depending on your company’s size and previous tax amount, you may be required to file and pay provisional consumption tax returns monthly, three times a year (May, August, November), or once a year by the end of August.

Important Note: Japan’s new Qualified Invoice System (QIS), introduced in October 2023, significantly impacts businesses. If your suppliers aren’t registered under QIS, you won’t be able to claim input tax credits. This could affect your financial planning and requires careful navigation.

Other Key Taxes

Don’t overlook fixed asset tax! It’s payable in four installments throughout the year, usually in April, July, December, and February, though specific dates can vary by municipality.

Unique Challenges for Foreign Subsidiaries

Transfer Pricing Documentation

If your company engages in transactions with foreign related parties, be prepared to submit detailed documentation, including Country-by-Country Reports, Master Files, and Local Files, under specific thresholds.

Thin Capitalization Rules

If your debt-to-equity ratio exceeds 3:1, you’ll need to navigate Japan’s thin capitalization rules, which limit interest deductions on loans from foreign parent companies.

Withholding Tax on Foreign Transactions & Tax Treaties

To optimize your tax strategy, ensure timely application of applicable tax treaties before payment dates. This requires careful coordination with your foreign counterparts and adherence to specific documentation requirements. You can find the necessary documents for each type of income on the National Tax Agency website: [National Tax Agency](https://www.nta.go.jp/taxes/tetsuzuki/shinsei/annai/joyaku/mokuji2.htm)
