What Is Reverse VAT? A Clear Explanation
VAT Value Added Tax is a consumption tax levied on the price of goods and services at each stage of the supply chain.
The price you see when looking at a UK shop is almost always £120 with 20% VAT built into it.
The question then becomes:
How much product is worth the £120?
How much is the tax?
Reverse VAT refers to extracting the tax component from a gross (inclusive of VAT) price, revealing the net (pre-tax) amount.
Key Terms:
Gross Price → Total paid (incl. VAT)
Net Price → Gross price without VAT
VAT Amount → Portion of tax which is included in gross
This backtracking is more than theory — it’s the day-to-day lifeblood of businesses, accountants and professionals across the world.

The Reverse VAT Formula:
The formula is straightforward:
Net amount = gross amount / (1 + VAT rate)
VAT amount = Gross Amount — Net Amount
Why This Works
The proposed gross price already includes VAT. Which means you need to divide instead of subtract.
Why You Can’t Just Subtract the Percentage
This mistake is probably the most common one.
Wrong:
£120 − 20% = £96
Correct:
£120 ÷ 1.20 = £100
The VAT was assessed on the net but not the gross — that’s why subtraction doesn’t work.
Step-by-Step Examples
Example 1 UK (20%)
Gross: £480
Net: £480 ÷ 1.20 = £400
VAT: £80
Example 2 UAE (5%)
Gross: AED 2,100
Net: AED 2,100 / 1.05 = AED 2,000
VAT: AED 100
Example 3 Ireland (23%)
Gross: €984.50
Net: €984.50 ÷ 1.23 = €800.41
VAT: €184.09
Example 4 South Africa (15%)
Gross: ZAR 3,450
Net: ZAR 3,450 / 1.15 = ZAR 3,000
VAT: ZAR 450
