Why Reverse Tax Calculation Matters
Receipts and invoices usually show only the tax-included total, so separating revenue from tax collected — for bookkeeping or cross-border comparisons — means working backward from that total. Dividing by (1 + rate) isn't the same as subtracting the rate, which is why selecting "Reverse" in the purchase-mode calculator above handles it exactly.
History & Context
Vietnam passed a new Corporate Income Tax Law effective October 1, 2025, overhauling incentive structures for priority sectors including semiconductor manufacturing, AI data centers, renewable energy, and automobile assembly — preferential rates as low as 10%, 15%, or 17% (versus the standard 20%) plus tax holidays for qualifying investments.
Vietnam has also extended a temporary 2% VAT rate cut for many sectors through 2026, targeting retail, automotive, and manufacturing specifically — part of a broader strategy to keep Vietnam competitive as a manufacturing alternative amid global supply-chain diversification away from China.
Business Use Case
A semiconductor manufacturer setting up operations in Vietnam after October 2025 can access preferential CIT rates and multi-year tax holidays specifically because Vietnam's new corporate tax law prioritizes high-tech manufacturing — a significant incentive difference compared to setting up in a non-prioritized sector.
Real-World Examples

Extracting VAT from a receipt total (reverse)
A receipt shows a ₫1,499.00 tax-included total in Vietnam at 10%:
- Pre-tax price: ₫1,499.00 ÷ (1 + 10%) = ₫1,362.73
- VAT: ₫1,499.00 − ₫1,362.73 = ₫136.27
