Quick Response
Download the detailed refund result, compare income, withholdings, deductions, and CLABE, and correct only verified errors. If the automatic refund does not apply, consider the Electronic Refund Form (FED) with supporting documentation.
When SAT does not refund your tax credit balance, review the result, classify the inconsistency, and decide whether to clarify, correct, or request via FED.

Before Acting
Do not delete deductions or change income just to get a different result. Each amended return must have a verifiable cause and keep its supporting documents.
What This Means in Practice
An unauthorized automatic refund does not mean the balance disappeared. The result may stem from differences in withholdings, deductions, income, bank data, or a case that must be processed through the Electronic Refund Form (FED).
The right decision depends on the reason. Correcting a return without understanding the rejection may reduce a correct balance or create new inconsistencies. First, compare what was declared with SAT's information and the original documents.

Frequently Asked Questions
Does an automatic rejection eliminate my right?
Not by itself. You must review the result, deadlines, and applicable procedure. In some cases, a manual request with supporting documentation is appropriate.
Should I file an amended return immediately?
Only if the return contains a real error. If the difference comes from the withholding agent's information or a CFDI, first correct the cause and document the change.
What if they authorized less?
Compare the authorized amount detail with the requested. The unauthorized portion may require correction, clarification, or FED, depending on the cause.
