Questione giuridica chiave
Whether input tax on the tractor purchase from E.________ SA could be deducted despite a defective receipt and incomplete form 1310.
Decisione estratta
No deduction was allowed because the receipt lacked the supplier's VAT registration number and did not create protected good faith; the reassessment was correctly upheld.
Motivazione estratta
Essential invoice elements under Art. 28 OTVA were missing, so Art. 29 para. 5 OTVA could not protect the taxpayer. The missing entries on form 1310 could not cure the defect.
