The digital invoice or nothing: the new mantra of the treasury
The Tax Administration Service has just issued a reminder that is more of an ultimatum. For the 2026 annual return, forget about deducting that payment to the dentist or the tuition if you did it with bills. Its message is clear: if there is no electronic trace, it does not exist for the Treasury.
Concepts such as medical, dental, hospital, nutrition, psychology and tuition expenses can only be deductible if they are made through electronic or bank means.
Translation: transfer, card or nominative check. Cash is officially out of the game. The justification, as always, comes wrapped in the cellophane of “traceability” and the fight against evasion.
The true cost of paying with bills
Here is the detail that hurts: you may have paid on time for your psychological consultation or for your child’s glasses. If it was in cash, that digital tax receipt (CFDI) that you took so much care of could be a dead letter. The wrong payment method voids everything.
Prodecon already has evidence of the disaster.
Organisations such as the Taxpayer Defense Attorney’s Office warned that one of the main causes of rejection of automatic refunds is precisely the registration of cash payments.
That is, they reject your refund even if the expense is real and legitimate. The form kills the substance. The authorities insist that this is for our own good, to “support the taxpayer’s economy.” Of course, always under its strict and increasingly narrow compliance.
The final message is unappealable: review your CFDI with a magnifying glass now. Any error in the payment method means goodbye to the deduction. In the war against evasion, the formal taxpayer pays first.
