Tax returns represent SAT declarations extracted for an entity, including annual, provisional, and RIF returns when available. A tax return contains the filing period, fiscal year, return type, operation number, payment information, source files, and whether ISSIF data is available. Use the PDF download endpoint when you need the original SAT transcript PDF. Use the tax return data endpoint when you need extracted financial variables or parsed return data instead of the tax return metadata. The returned data depends on the return type, fiscal year, tax regime, and the files SAT provides for that return.

Extracting Tax Return Data

Create an extraction for the tax return type you need:
Tax return dataExtractor
Annual returnsannual_tax_return
Provisional monthly returnsmonthly_tax_return
RIF returnsrif_tax_return
{
  "entity": "/entities/7b3a25a9-a53a-4846-abe6-f2574c9c2d5d",
  "extractor": "annual_tax_return",
  "options": {
    "period": {
      "from": "2020-01-01",
      "to": "2024-12-31"
    }
  }
}
Use monthly_tax_return or rif_tax_return in the same request shape when you need those return types. After the extraction reaches finished, read the resulting tax returns from the entity tax return list.
