Pitfall Guide: Common Bookkeeping & Tax Violations
❌ Mistake 1: Incomplete receipt records / claiming they're lost
If a tax audit finds expenses without receipts, they're disallowed — plus back taxes, late-payment tax, and an underreporting penalty (10–35%). Since Jan 2024, the Electronic Bookkeeping Act requires thatInvoices received electronically must be stored electronically; a paper printout is not accepted.
❌ Mistake 2: Issuing an "invoice-like" bill without Qualified Invoice registration
Issuing an invoice marked with "consumption tax" without being a registered Qualified Invoice Issuer means your client's input tax credit is denied → Your client seeks damages + your reputation collapses. If you're mainly B2B, register for Qualified Invoices early.
⚠ Mistake 3: Booking personal spending as company expenses
Mixing personal dining, entertainment, or travel into company expenses gets reclassified as a "director's bonus" in an audit — non-deductible, with withholding tax owed on top.Keep business and personal accounts strictly separate; entertainment expenses must record the recipient and purpose.
⚠ Mistake 4: Panic-buying "tax-saving products" right before year-end
Buying insurance, vehicles, or real estate just before year-end to save tax may be ruled "non-deductible" for tax purposes.Tax saving must be planned, you should start estimating 3 months before year-end.

FAQ
My company is newly formed — when does first-period bookkeeping start?

Based on your Contract date & fiscal year-end Calculation:

  • Start month: contract on or before the 15th → includes that month; after the 15th → starts the next month
  • Fiscal year-end: based on the fiscal year-end you set (e.g., March)
  • Counting the months: the number of months from the start month to year-end;If 6 months or less, billed as 7 Billing

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)

If sales just cross ¥10M, do I need to switch plans right away?

No need to switch mid-period. But note:

  • The period after sales exceed ¥10M, the 2nd period , you automatically become a consumption-tax taxable enterprise
  • WBCG identifies this at year-end and alerts you
  • Switch to Plan B (¥22,000/mo) + add consumption-tax filing (¥66,000/yr) from the next period

As sales approach ¥10M, we recommend starting Qualified Invoice registration and electronic bookkeeping 1–2 months in advance.

Can I do monthly bookkeeping myself and have WBCG do only the year-end filing?

Yes — this is called a "spot closing."Costs about ¥220,000–330,000/year depending on the state of your books. Drawbacks:

  • Without professional oversight month to month, errors are common and clean-up fees add up
  • By the time you spot a problem it's too late to correct retroactively
  • Tax consultations only at year-end

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.

What's the difference between blue-form and white-form returns?

Companies must use blue-form returns(generally). The difference:

  • Blue-form: tax-saving benefits (10-year loss carryforward, special depreciation, loss carryback refunds, etc.); requires double-entry bookkeeping and a balance sheet
  • White-form: no tax-saving benefits; simple bookkeeping

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.

How does the Electronic Bookkeeping Act affect my company?

Fully effective from January 2024. Three key points:

  • Electronic transactions: invoices received via email, e-commerce, or the web must be stored electronically — paper is not a substitute
  • Ensuring authenticity: requires a timestamp or an internal handling policy
  • Ensuring visibility: must be searchable by date, amount, and counterparty

Violations may lead to loss of blue-form status, estimated taxation, etc. WBCG provides:

  • Setup of an Electronic Bookkeeping Act–compliant system (+¥44,000 one-time)
  • Compliance is checked automatically during monthly bookkeeping
Can my company be handled bilingually (Japanese + Chinese)?

Yes.The entire WBCG team is fluent in Chinese (Traditional & Simplified), Japanese, and English. Choose how you'd like to work with us:

  • Tax consultations → explained in Chinese (in language you understand)
  • For third parties like the tax office and banks → we handle it in Japanese
