Compute recoverable input VAT for businesses making both taxable (15.5% / zero-rated) and exempt supplies. Includes the de minimis test under the VAT Act.
Use values for the VAT period (typically a month). All figures VAT-exclusive.
Ratio = Taxable ÷ (Taxable + Exempt)
If taxable use of mixed inputs is ≥ 90%, claim 100% of the mixed input VAT (s. 16(1) proviso (a)). Direct-exempt input VAT stays non-deductible.
Input VAT directly tied to a taxable supply: 100% claim. Tied to an exempt supply: 0%.
Mixed input VAT × supplies ratio = recoverable.
At year-end, redo the apportionment with full-year supplies and adjust monthly claims if material.
