Invoice 4.0 ‘threatens’ taxpayer deductions

38% of the CFDI cancellations (invoices) occur unexpectedly, generating a negative impact on the deductibility of expenses for companies, it is also estimated that between 18% and 25% of the invoices that SMEs have received in recent months contain errors.

“Today, in addition to all the fields that were already requested, they now ask us to correctly enter the issuer of the invoice, the postal code and tax regime, which are the new fields that are problematic because if they give you a wrong number it is as if they did not issue the invoice, and in the end they are not deductible, you cannot prove them, so you pay more for taxes”, Rafael Soto, CEO of Box Factura, explained in an interview.

The obligation to comply with the version 4.0 of the invoices issued and approved by the Tax Administration Service (SAT) comes after four extensions, it entered into force last April, originally it was intended to be implemented at the beginning of 2022, then the obligation was postponed.

The request for just two new data has caused errors due to different factors, including that “we do not have a tax culture, everyone ignores the tax issue, so it is not given the importance and seriousness that the issue needs, there are supplier companies that do not request the new data from the client, they put the ones that are not updated or those that are default”, commented the manager.

So when companies realize this, the time has passed to be able to correct the or the mistakes.

The study refers that around 5.44% of the invoices issued by third parties contain errors that affect the business tax deduction.

The most common errors are incorrect postal code (2.98%), incorrect tax regime (0.89%) and CFDI version 3.3 (1.57%).
