IRS: I Didn't Validate My Invoices. Now What?
The deadline to validate invoices ended on Monday. There are still some things you can do, others that are no longer possible - and consequences you should know to avoid surprises when settling your tax.
The deadline has passed. Now what?
This year, the deadline to validate invoices ended on March 2nd, meaning it is no longer possible to classify expenses through e-fatura. However, this does not mean all deductions are lost.
Some types of expenses may not even appear in e-fatura, as they are communicated directly to the tax authority by the entities. These expenses should appear in the tax deductions consultation.
Examples of automatically communicated expenses:
- Health expenses communicated by hospitals and clinics
- Tuition and education fees reported by educational institutions
- Mortgage interest
- Rent communicated by the landlord
Is it still possible to get some deductions?
Not all deductions are lost - particularly those communicated directly to the tax authority. However, non-validation may result in the loss of deductions in categories such as restaurants, car workshops, hairdressers, and veterinarians.
What are the consequences?
⚠️ Without classified and validated invoices, there is a loss of at least part of the deductions - which can reduce your refund or increase the tax to pay.
What to do from now on?
If you didn't validate your invoices in time, follow these steps to minimize the impact:
- Check the Finance Portal for expenses already automatically communicated
- Between March 16 and 31, consult the tax deductions and confirm the calculated values
- If you find errors or missing values, file a complaint with the Tax Authority
- Evaluate if you have expenses that can be manually declared in Annex H
