Based on your Contract date & fiscal year-end Calculation:
Example: contract on 4/22 (after the 15th) + June fiscal year-end → start month May, 2 months → billed as 7 months = ¥77,000 (¥11,000 × 7)
No need to switch mid-period. But note:
As sales approach ¥10M, we recommend starting Qualified Invoice registration and electronic bookkeeping 1–2 months in advance.
Yes — this is called a "spot closing."Costs about ¥220,000–330,000/year depending on the state of your books. Drawbacks:
Over the long run, monthly bookkeeping from ¥11,000 × 12 = ¥132,000 + year-end closing ¥110,000 = ¥242,000/year. Close to a one-time job in cost, but far more valuable.
Companies must use blue-form returns(generally). The difference:
Blue-form eligibility applies after incorporation Within 3 months You file a "Blue-Form Return Approval Application" with the tax office; miss the deadline and you're stuck with white-form that year, switching only the next. WBCG files it at incorporation, so you won't miss it.
Fully effective from January 2024. Three key points:
Violations may lead to loss of blue-form status, estimated taxation, etc. WBCG provides:
