# List Tax Codes By Company

GET https://rest.avatax.com/api/v2/companies/{companyId}/taxcodes

> **Access control:** this endpoint is available to users with the `everyone` role.

List all taxcode objects attached to this company.
A 'TaxCode' represents a uniquely identified type of product, good, or service.
Avalara supports correct tax rates and taxability rules for all TaxCodes in all supported jurisdictions.
If you identify your products by tax code in your 'Create Transaction' API calls, Avalara will correctly calculate tax rates and
taxability rules for this product in all supported jurisdictions.
            
Search for specific objects using the criteria in the `$filter` parameter; full documentation is available on [Filtering in REST](http://developer.avalara.com/avatax/filtering-in-rest/) .
Paginate your results using the `$top`, `$skip`, and `$orderby` parameters.
