# Tax returns

> Get the annual income tax returns (F22 form) a taxpayer filed at the Servicio de Impuestos Internos (SII): declared salaries and fees, taxes withheld, the refund requested, and the bank account that receives it.

This page explains what a tax return is and which amounts it includes. For every attribute, see the [Tax return object](/api/fiscal-api/tax-returns/tax-returns-object).

## What a tax return is

In Chile, taxpayers declare their income tax once a year to the Servicio de Impuestos Internos (SII) with the F22 form (Operación Renta). The form sums up the income of the previous calendar year and the taxes already withheld. The resulting balance is either a refund the SII pays into the taxpayer's bank account, or an amount the taxpayer owes.

A `TaxReturn` is one filed F22 form. Fintoc returns one `TaxReturn` per fiscal year.

Tax returns are available for `Links` connected to the SII (`cl_fiscal_sii`). Create the `Link` with the `tax_returns` product.

Amounts are integers in CLP, the smallest unit of the currency.

## Endpoints

[List tax returns](/api/fiscal-api/tax-returns/tax-returns-list) returns the tax returns of the `Link`, paginated. [Get a tax return](/api/fiscal-api/tax-returns/tax-returns-get) returns one tax return by `id`.

## How Fintoc fetches tax returns

Fintoc fetches the filed returns when your user creates the `Link`. Tax returns aren't refreshed periodically, so to get a return filed after the connection, create a new `Link`.
