Deadline for validating invoices pending in the E-Invoice

Until 15 February, taxpayers must access e-invoice with their respective access passwords to the Finance Portal and/or citizen card or digital mobile key and check whether they have invoices registered with the status "pending". If so, they should clarify to the Tax Authority system whether or not the respective invoices are eligible for some of the tax benefits associated, either to general and family expenses, or to the right to deduct VAT by requiring an invoice (motorbike and car repairs, restaurants and accommodation, hairdressers and veterinarians, social passes).
Any expense that intends to be declared in order to benefit from one of the mentioned deductions must be validated/registered in the e-invoice until 15 February or it cannot be registered afterwards. The same does not apply, for example, to health or other expenses. They should also, if necessary, register invoices that are not in the system but for which the taxpayer is in possession of a paper copy.

Deadline and means for complaining about erroneous invoices and the like

Please note that if you detect invoices for general and family expenses or expenses with the right to deduct VAT by the requirement of the invoice registered with wrong information or some other problem you should complain to the Tax Authority between 1st and 15th of March.
To do this you can use the "Expenses for Deductions" option available from Home => Your Services => Deliver => Administrative Appeals => Expenses for Deductions or use alternative methods such as contacting a tax office directly or making a written claim.

E-Invoice Complaint Deadline and Where to Complain

Invoices for expenses with public schools or the National Health Service are usually loaded into the system at a later stage and therefore should not be listed in the first weeks of the year, and may be included in the annual tax return when filling it in if they do not appear automatically pre-filled, included in the overall figures for annual expenditure in each of the expenditure categories. You don't have to worry, for example, about registering receipts for user charges.
Please also note that if the expenses relate to dependents of the household (children) they will not appear in the account of the income-holders, but in the children's Finance portal/invoice account. The invoices will however be aggregated in the aggregate, if this is foreseen in the tax legislation.
