What is VAT & Withholding Tax?
Value Added Tax (VAT) is a consumption tax placed on goods and services at each stage of the supply chain. It's collected by businesses and remitted to the government.
Withholding Tax (WHT) is tax deducted at source from payments like services, rent, professional fees, or dividends. The payer withholds the tax and remits it directly to tax authorities.
Quick Fact
In Thailand: VAT is 7% on most goods/services, while WHT ranges from 1-5% depending on service type. Both taxes serve different purposes and are calculated separately!
How to Add VAT
When setting a selling price or invoicing a client, add VAT using this formula:
Price: Amount before VAT (net amount)
VAT Rate: Tax percentage (e.g., 7 for Thailand)
Total: Final price including VAT
Example: Adding 7% VAT in Thailand
Service Fee: ฿10,000
Step 1: VAT = 10,000 × 0.07 = ฿700
Step 2: Total = 10,000 + 700 = ฿10,700
Or directly: 10,000 × 1.07 = ฿10,700
Invoice amount including 7% VAT: ฿10,700 ✅
How to Remove VAT
When you have a VAT-inclusive amount and need to extract the net amount (for accounting or VAT claims), use this formula:
Total: Price including VAT
Net Price: Amount before VAT
VAT Amount: Tax portion to extract
Example: Removing 7% VAT in Thailand
Invoice Total: ฿10,700
Step 1: Net = 10,700 ÷ 1.07 = ฿10,000
Step 2: VAT = 10,700 − 10,000 = ฿700
Result: Net: ฿10,000 | VAT: ฿700 ✅
Perfect for VAT claims and accounting! 📊
Common Mistake to Avoid
Don't just subtract VAT rate from total to remove VAT!
❌ Wrong: 10,700 × 0.93 = 9,951 (incorrect)
✅ Correct: 10,700 ÷ 1.07 = 10,000 (correct)
Always divide by (1 + rate), not multiply by (1 − rate).
Withholding Tax Explained
Withholding Tax (WHT) is deducted from payments before they reach the recipient. The payer is responsible for withholding and remitting the tax to authorities.
Base Amount: Payment amount before WHT
WHT Rate: Withholding tax percentage
Net Received: Amount after tax deduction
Example: 3% WHT on Service Payment
Service Fee: ฿10,000 (before VAT)
Step 1: Add VAT (7%) = 10,000 × 1.07 = ฿10,700
Step 2: Calculate WHT (3% of base) = 10,000 × 0.03 = ฿300
Step 3: Net Received = 10,700 − 300 = ฿10,400
Recipient receives ฿10,400 after WHT deduction 💼
Important: WHT Base Calculation
In most jurisdictions including Thailand, WHT is calculated on the base amount (before VAT), not the VAT-inclusive total. Always verify local tax rules for your specific situation.

Real Tax Calculation Examples
Example 1: Thai Freelancer Invoice
Service: Web Development, ฿50,000
Step 1 - Add VAT (7%):
VAT = 50,000 × 0.07 = ฿3,500

• Net to Consultant = 2,400 − 300 = £2,100
