For entrepreneurs and administrative staff in Taiwan, the Handwritten Triplicate Government Uniform Invoice (手寫三聯式統一發票) is a unique business staple. While much of the world has moved to fully digital receipts, these “hand-inked” booklets remain the legal backbone for many B2B (Business-to-Business) transactions in Taiwan.
However, because these documents are used to claim a 5% VAT deduction, the Ministry of Finance has incredibly strict rules for filling them out. One wrong stroke of a pen can render the invoice invalid.
The Anatomy of the Triplicate GUI
Every time you write an invoice, you are creating three layers of records using carbon paper:
- Copy 1 (Retention – 存根聯): Stays in your booklet for your own accounting.
- Copy 2 (Deduction – 扣抵聯): Given to the buyer to claim their tax credit.
- Copy 3 (Receipt – 收執聯): Given to the buyer as a legal payment voucher.
Why Is it So Difficult to Fill Out?
The challenge of the handwritten invoice isn’t just the penmanship; it’s the zero-tolerance policy for errors.
1. No Corrections Allowed
You cannot use white-out, correction tape, or cross out mistakes. If you make a typo, the entire set must be marked “VOID” and stapled back into the booklet. You must then start over on a fresh page.
2. Formal Financial Chinese
To prevent tampering, the Total Amount must be written in formal financial characters. For example, writing “二” (two) is not allowed because it is too easy to change into “三” (three).
3. The 5% VAT Math
You must manually calculate:
- Sales Amount: The subtotal before tax.
- VAT: Exactly 5% of the sales amount.
- Total: The sum of both.
