Guide to purchasing software with a VAT number: invoicing and deduction
Find out how to request an electronic invoice for business software, how intra-Community VAT works, and how to correctly deduct costs.

How to request an electronic invoice for software
When purchasing software for your professional or business activity, the invoice must be requested at the same time as the order. During the payment details entry phase, it is necessary to fill in the specific fields dedicated to invoicing. To allow the correct transmission of the document through the Exchange System (Sistema di Interscambio) of the Revenue Agency (Agenzia delle Entrate), you must enter the complete company name, the VAT number, and the SDI recipient code or the certified email address (PEC).
If this data is not entered at the time of purchase, the transaction is recorded as a sale to a private individual and it will no longer be possible to issue the invoice at a later date. The electronic invoice will then be delivered directly to your tax drawer (cassetto fiscale) or to the management channel linked to the indicated recipient code.
The VAT regime for companies and the reverse charge
For VAT taxable persons purchasing software licenses from suppliers located in other countries of the European Union, the rules of tax territoriality apply. If the purchasing company or professional possesses a registered and valid VAT number within the VIES system, the transaction is not subject to the charging of VAT on the invoice by the seller.
In this scenario, the reverse charge mechanism applies. The Italian buyer will receive an invoice without the application of the tax and must proceed to integrate the document with the rate in force in Italy, registering the transaction in both the sales register and the purchases register. It is the buyer's responsibility to verify the validity of their VAT number in the European system before completing the transaction.
Tax deduction and document preservation
Software licenses purchased for professional purposes represent a cost inherent to the business or self-employed activity. From a tax perspective, the expense incurred for the purchase of computer programs and operating systems is fully deductible as an operating cost in the year of purchase, or it can be amortized over several years depending on the type of license and the accounting criteria applied by your tax advisor.
In order to benefit from the deduction of the cost and the deduction of the tax, it is essential to carefully preserve the electronic invoice received. In addition to the invoice, it is also recommended to keep the proof of payment and the delivery emails of the license codes, which attest to the actual use of the software within the business organization.
What changes for private customers without a VAT number
For private consumers who do not purchase the software for professional purposes and do not possess a VAT number, the procedure is different. In this case, it is not necessary to indicate recipient codes or PEC. The purchase is treated as a normal retail transaction and the final price paid already includes the Italian VAT applied according to the rates in force.
Private individuals receive a purchase confirmation and a tax receipt certifying the payment. This document cannot be used to write off taxes or to recover the tax, but it serves as proof of purchase for the warranty and for the technical assistance of the software. For private individuals as well, it is advisable to keep the receipt together with the activation codes of the program.
