Filing calendar
Plan the quiet weeks so the odd-month deadline is not a surprise
This calendar is a planning aid for tax readiness around Taiwan’s quarterly business-tax rhythm. Confirm exact statutory dates with your preparer or the National Taxation Bureau for your situation.
Suggested rhythm for one quarter
-
Even month · weeks 1–2
Book a mid-quarter ledger check-in if sales mix or staffing changed. Close obvious coding errors while suppliers still answer quickly.
-
Even month · weeks 3–4
Run a document sort so invoice folders match how your bookkeeper files. Start the missing-document list with named owners.
-
Odd month · weeks 1–2
Schedule the Quarterly Tax Readiness Review. Aim to finish the findings call at least five business days before you intend to submit.
-
Odd month · filing week
Use a hand-off session if your preparer needs the readiness note translated into line-level actions. Do not start a first-time readiness review in this week unless capacity allows rush work.
Indicative windows (planning only)
| Period focus | Prefer check-in | Prefer readiness review |
|---|---|---|
| Jan–Feb activity → Mar filing window | February week 2 | Early March |
| Mar–Apr activity → May filing window | April week 2 | Early May |
| May–Jun activity → Jul filing window | June week 2 | Early July |
| Jul–Aug activity → Sep filing window | August week 2 | Early September |
| Sep–Oct activity → Nov filing window | October week 2 | Early November |
| Nov–Dec activity → Jan filing window | December week 2 | Early January |
Dates shift with weekends, holidays, and your exact filing obligations. Treat this as capacity planning for reviews, not legal advice.
