# Tax returns

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.

## How tax return data is collected

Tax returns are collected with different extractors depending on the return type:

| Tax return data             | Extractor            |
| --------------------------- | -------------------- |
| Annual returns              | `annual_tax_return`  |
| Provisional monthly returns | `monthly_tax_return` |
| RIF returns                 | `rif_tax_return`     |

After the extraction finishes, the resulting records are available from the entity tax return list.
