Case
On 18/11/2026 Delta S.r.l. issues immediate electronic invoice no. 412 (document type TD01) to Zeta S.p.A., transmitted to the SdI. Figures are fictitious and used for teaching purposes. DOCUMENT LINES — line 1: pre-packed food products, taxable amount 4.000,00, rate 10%, tax 400,00; line 2: household goods, taxable amount 6.000,00, rate 22%, tax 1.320,00; line 3: non-returnable packaging charged to the customer, ancillary to the supply on line 2 and therefore subject to the same rate under art. 12 d.P.R. 633/1972, taxable amount 200,00, rate 22%, tax 44,00; line 4: deposit on returnable packaging, 500,00, excluded from the taxable amount under art. 15, c. 1, n. 4, d.P.R. 633/1972 because refund on return is expressly agreed in the contract, codice Natura N1; line 5: reimbursement of transport costs advanced in the name and on behalf of the customer, with the carrier invoice made out to Zeta S.p.A. and duly documented, 180,00, excluded under art. 15, c. 1, n. 3, codice Natura N1; line 6: stamp duty settled virtually and recharged, 2,00, codice Natura N1. VAT SUMMARY IN THE XML FILE — taxable amount at 22%: 6.200,00 with tax of 1.364,00; taxable amount at 10%: 4.000,00 with tax of 400,00; amounts not subject to VAT under Natura N1: 682,00; total tax 1.764,00; document total 12.646,00. DatiBollo block completed: BolloVirtuale = SI, ImportoBollo = 2,00. Payment terms: 60 days; deadline for returning the packaging: 90 days from delivery.
Business event
Delta S.r.l. records, in a single entry, invoice no. 412, distinguishing the components that generate revenue (the two supplies at different rates and the charge for non-returnable packaging, ancillary under art. 12), the components that do NOT generate revenue but move payable or receivable positions already in existence (the deposit on returnable packaging, which is a payable to the customer; the reimbursement of the disbursement, which clears the receivable arising when Delta paid the carrier in the name and on behalf of the customer; the recharge of the stamp duty, which feeds the payable to the Erario, the Italian tax authorities, for virtual stamp duty) and output VAT, which is the sum of the tax on the taxable lines alone. On return of the packaging within the agreed deadline Delta refunds the deposit; if the deadline passes without return, the deposit retained ceases to qualify under art. 15, n. 4, becomes consideration and must be invoiced with VAT.

Before posting, check
- Balancing of the VAT summary against the document total and against the accounting records. Taxable amount at 22% = 6.000,00 + 200,00 of non-returnable packaging (ancillary under art. 12) = 6.200,00, tax 1.364,00; taxable amount at 10% = 4.000,00, tax 400,00; not subject under N1 = 500,00 + 180,00 + 2,00 = 682,00. Document total: 6.200,00 + 4.000,00 + 682,00 + 1.764,00 = 12.646,00, equal to the balance debited to Trade receivables. The output VAT account takes 1.764,00 and not 1.764,00 plus something else: the N1 lines generate no tax. In the sales register the document produces two taxable lines and one non-subject line that does not feed the periodic VAT settlement.
- Separate qualification of the items falling outside the taxable amount, which is where the exercise is either passed or failed. The deposit on returnable packaging is excluded under art. 15, c. 1, n. 4, d.P.R. 633/1972 only if refund on return is expressly agreed: without a written agreement it is taxable consideration. The reimbursement of transport costs is excluded under art. 15, c. 1, n. 3, only if the disbursement is incurred in the name and on behalf of the customer and duly documented by a carrier invoice made out to the customer: if the document is made out to Delta, the charge becomes an ancillary cost under art. 12 and follows the rate of the principal supply. In both cases the correct code is N1 (excluded under art. 15) and not N2 (outside the scope for want of a chargeable event) or N4 (exempt). None of the three amounts counts towards the volume d'affari (turnover for VAT purposes, art. 20 d.P.R. 633/1972), a point that matters for the plafond of esportatori abituali (regular exporters) and for size thresholds.
- Check on the stamp duty. Stamp duty of 2,00 euro is due because the amounts not subject to VAT — 680,00, net of the duty itself — exceed the limit of 77,47 euro (d.P.R. 642/1972, Tariffa Parte I, art. 13, and Tabella allegato B). On electronic invoices the duty is settled virtually by completing the DatiBollo block of the XML, with assessment and payment on a quarterly basis according to the lists drawn up by the Agenzia delle Entrate from the data of the invoices passed through the SdI (d.m. 17 giugno 2014). CONTROVERSIAL POINT to be flagged in class: the recharge of the stamp duty to the customer is treated here as reimbursement of a disbursement under art. 15, c. 1, n. 3, but a different view holds that, not being a cost incurred in the name and on behalf of the customer, the recharge is an ancillary cost under art. 12 and must form part of the taxable amount at the rate of the principal supply. One treatment must be chosen and kept consistent across the XML file, the VAT registers and the general ledger; the choice must be documented because it affects the taxable amount and the tax.
- Consistency check on the deposits account. The balance of Payables for deposits on returnable packaging must be matched by a subledger by customer and by the inventory of packaging held on customers' premises. At each period-end close the positions whose return deadline has expired must be extracted: for these the basis of the exclusion has fallen away and an invoice must be issued as in entry 3, charging 500,00 with VAT of 110,00. Entries 2 and 3 are alternatives and must not be added together.
