Invoices appear throughout the year, but validation should be completed within the deadlines defined by the Tax Authority.
There is no fee to view or validate invoices. The real cost is tax-related: unresolved items can reduce your IRS deductions.
- Ignoring pending invoices until after the validation deadline.
- Accepting the wrong expense category and lowering the deduction amount.
- Forgetting to request an invoice with your NIF and trying to fix everything too late.
Do I need to validate every invoice manually?
No. Many invoices are categorised automatically. You mainly need to intervene when a category is missing, incorrect or pending confirmation.
What happens if I miss the deadline?
Your expenses may not count correctly toward IRS deductions. Reviewing pending items early is the safest approach.
