Pro rata
The rule that limits input-IGI deductions when an activity includes transactions both with and without a right to deduct.
If part of your activity does not carry a deduction right, you cannot deduct all input tax—only the proportion attributable to the activity that does.
An example
An entity carrying out both exempt and taxable activities may need to apply a pro-rata calculation.
The typical mistake
Ignoring the rule because the exempt activity is small. If the rule applies, it must be calculated; a small amount does not make it disappear.
How it appears in AndCompta
When you carry out transactions both with and without a deduction right, the input-IGI register keeps them separate from day one. Otherwise, calculating pro rata at year-end means reconstructing the whole year.
