Burundi VAT calculator
Add or extract the 18% standard VAT. The 10% and 0% treatments require an exact Article 15 classification and retained evidence.
Formula and worked check
Add: VAT = net × rate; gross = net + VAT. At 18%, BIF 100,000 gives VAT BIF 18,000 and total BIF 118,000.
Extract: net = VAT-inclusive amount ÷ 1.18; VAT = gross − net.
Arithmetic retains full precision. Whole-BIF display is an AfroTools presentation rule, not an OBR rounding rule.
