• Products that do not fit: You will not be able to deduct expenses for unprescribed sunglasses, nor the aesthetic part of the glasses. Products covered by public aid or medical insurance do not enter into the part that is already subsidized.
• Expenses from January 1 to December 31 from 2025: If the declaration we make in 2026 is called “Income 2025” it is because it corresponds to the last fiscal year. Therefore, only the expenses you have made throughout 2025 count, neither those before nor after.
• Traceable payments: It is not advisable to make payments in cash. It is better to make payments traceable by the Treasury so that it can be verified correctly. Therefore, payments you have made using debit or credit cards, bank transfers, Bizum or direct debit receipts. In cases of accounts with multiple owners, marital money or shared payments, each community has specific rules for distributing the deduction between spouses.
