# List tax returns

## ▶️ Usage

 With the List Tax Returns method, you can:

  1. List tax returns related to a specific  (using the  query parameter).
  2. Get the details of a specific  (using the  query parameter).
  3.  List all tax returns related to your Belvo account (without using any query parameters).

  ## 📖 Pagination
  
  This method returns a paginated response (default: 100 items per page). You can use the  query parameter to increase the number of items returned to a maximum of 1000 items. You can use the  query parameter to navigate through the results. For more details on how to navigate Belvo's paginated responses, see our Pagination Tips article.
