The deadline for validating invoices for IRS purposes extends until February of the following year, but doing so throughout the year prevents a last-minute rush. Invoice validation is crucial to ensure tax deductions.
“The validation and classification allow a percentage of these expenses to be deducted from the IRS amount. This results in a lower tax bill,” stated a post shared by the Tax Authority (AT) on Instagram.
Taxpayers can validate invoices through e-Fatura, a “online platform where invoices issued with your taxpayer number and reported to the AT are recorded and categorized,” explains the Tax Office.
So, where can invoices be validated?
According to the AT, invoices for IRS purposes can be validated:
- On the Finance Portal > e-Fatura
- In the e-Fatura App. “Here, you can add other family members and validate all invoices. It also allows you to classify all invoices associated with the vendor’s taxpayer number at once.”
- In the ATGo App, “if you are a self-employed worker or a sole proprietor.”
Until when can invoices be validated? Invoices can be validated “until the end of February of the following year.”
Attention!
In the same post, the Tax Office reminds taxpayers to keep the invoices reported to the Tax Office, “for a period of 4 years from the end of the year in which the purchase occurred.”
Can I classify invoices related to professional activity expenses? Yes. The AT explains that “invoices can be for personal or professional expenses, so classification is necessary.”
“For invoices related to professional activity, you must indicate whether they relate wholly or partly to the activity,” the post reads.
As a buyer can I report invoices without the taxpayer number?
Yes, according to the AT, “through the e-Fatura App, using the QR Code reader for reading and reporting invoices.”

The last installment of the IMI can be paid until December 2. Many properties may be taxed as new when they are not, and thus could have their tax value reduced, but requesting a new evaluation from the Tax Office may also increase the tax payable. Simulate your case.
If I miss the deadline, will unvalidated health, education, homecare, and property expenses be lost?
“They are not lost, but if you do not validate them within the deadline, these expenses will no longer be automatically considered by the Tax Office. You will need to declare these deductions manually on the IRS statement,” explains DECO PROTeste.
Will expenses with VAT benefit not validated until February 28 be lost?
According to DECO PROTeste, the answer is yes: “Until February 28, you have the opportunity to recover the VAT spent on public transport travel and the VAT incurred on certain expenses. This includes 15% of the VAT incurred on dining, accommodation, car or motorcycle repair shops, hairdressers, and beauty institutes, gyms and other sports or physical activity spaces; 35% on veterinarians and veterinary medicines; and 100% of the VAT incurred on public transport and newspaper and magazine subscriptions. If you do not do this in time, you will not have the opportunity to declare these expenses on the IRS statement.”
