How to Calculate VAT Correctly: Step-by-Step Guide with Real Examples

VAT calculation mistakes are one of the most common causes of FTA penalties. This practical guide shows you exactly how to calculate VAT correctly in different scenarios, with real examples you can apply to your business immediately.

Basic VAT Calculation Formula

VAT Amount = Net Amount × 5%

Total Amount (Including VAT) = Net Amount + VAT Amount

Example 1: Basic VAT Calculation

Scenario: Restaurant Meal

Net Amount: AED 100

VAT Calculation: AED 100 × 5% = AED 5

Total Amount: AED 100 + AED 5 = AED 105

What to show on invoice:

  • Net Amount: AED 100
  • VAT (5%): AED 5
  • Total: AED 105

Example 2: VAT Calculation with Discounts

Scenario: Electronics Store with 10% Discount

Original Price: AED 1,000

Discount: 10% = AED 100

Net Amount After Discount: AED 900

VAT Calculation: AED 900 × 5% = AED 45

Total Amount: AED 900 + AED 45 = AED 945

What to show on invoice:

  • Original Price: AED 1,000
  • Discount: -AED 100
  • Net Amount: AED 900
  • VAT (5%): AED 45
  • Total: AED 945

Example 3: Reverse Charge VAT Calculation

Scenario: Importing Services from Outside UAE

Service Cost: AED 50,000

VAT Calculation: AED 50,000 × 5% = AED 2,500

What you need to do:

  • Record AED 2,500 as Input VAT (recoverable)
  • Record AED 2,500 as Output VAT (payable)
  • Net effect: AED 0 (if you have other output VAT)

Journal Entry:

  • Dr. Service Expense: AED 50,000
  • Dr. Input VAT: AED 2,500
  • Cr. Output VAT (Reverse Charge): AED 2,500
  • Cr. Accounts Payable: AED 50,000

Example 4: Mixed Rate Calculations

Scenario: Hotel Invoice with Different Services

Room Rate (Standard Rate): AED 500

Restaurant (Standard Rate): AED 200

International Calls (Zero-rated): AED 50

VAT Calculations:

  • Room VAT: AED 500 × 5% = AED 25
  • Restaurant VAT: AED 200 × 5% = AED 10
  • International Calls VAT: AED 50 × 0% = AED 0

Total VAT: AED 25 + AED 10 + AED 0 = AED 35

Total Amount: AED 750 + AED 35 = AED 785

Common VAT Calculation Mistakes to Avoid

❌ Mistake 1: Calculating VAT on VAT

Wrong: AED 100 × 5% = AED 5, then AED 105 × 5% = AED 5.25

Correct: AED 100 × 5% = AED 5 (VAT is only on net amount)

❌ Mistake 2: Including VAT in Net Amount

Wrong: If total is AED 105, VAT = AED 105 × 5% = AED 5.25

Correct: Net = AED 105 ÷ 1.05 = AED 100, VAT = AED 5

❌ Mistake 3: Rounding Errors

Wrong: AED 33.33 × 5% = AED 1.67 (rounding each item)

Correct: Total net AED 100, total VAT AED 5 (round at total level)

VAT Calculation Checklist

  • ✅ Always calculate VAT on net amount (excluding VAT)
  • ✅ Use 5% rate for standard supplies
  • ✅ Use 0% for zero-rated supplies
  • ✅ Apply reverse charge for imported services
  • ✅ Round VAT to 2 decimal places
  • ✅ Show net amount, VAT amount, and total separately
  • ✅ Include TRN on all invoices
