# Creating and Editing Company Codes in Lucanet VAT

## Overview

In the **Company codes** workspace in Lucanet VAT (Value Added Tax), you store the accounting identifier from the ERP system for a company. In SAP, the company code number often differs from the company number. Maintain the company code separately in VAT for this reason.

As a rule, a company has exactly one company code. In special cases, for example with several company codes on different ERP systems or with a change of the company code during the year, you map the company via company subdivisions or via several company codes.

[Tax codes](https://support.lucanet.com/en/documentation/income-taxes/vat/master-data/create-and-configure-tax-codes.md) and the [tax code mapping](https://support.lucanet.com/en/documentation/income-taxes/vat/master-data/create-and-edit-tax-code-mapping.md) require a company code. Only companies whose declarations you enter exclusively manually do not need a company code. In addition, you assign [reconciliation accounts](https://support.lucanet.com/en/documentation/income-taxes/vat/master-data/create-and-edit-reconciliation-accounts.md) to a company code.

When you import the declaration values in the **Value Added Tax** functional area, VAT checks whether the company code from the ERP reports is stored here. For more information, see the [Importing Data for a Single Company](https://support.lucanet.com/en/documentation/income-taxes/vat/value-added-tax/import-single-company.md) page.

## Navigation to the 'Company Codes' Workspace in VAT

The **Company codes** workspace can be found under **VAT | Master data | Company codes** and is displayed as follows, for example:

    ![Shows the page for creating a company code in VAT with the 'Save' button, the mandatory field 'Company code' with the value '1002' and the character counter '4 / 4', and the 'Comment' field.](https://support.lucanet.com/assets/docs-images/income-taxes/vat/master-data/create-and-edit-company-codes/_images/en/company-codes-detailed-view.png)
    Page for creating a company code

2. In the **Company code** field, enter the identifier of the company code. The value must match the identifier in the ERP system exactly so that VAT imports the declaration values without errors. Up to four letters, digits, or special characters without spaces are permitted.

3. If necessary, enter an internal note on the company code in the **Comment** field. The comment is for information purposes only; VAT does not transfer the comment to the reporting files.

4. Click **Save**.

## Editing a Company Code in VAT

For an existing company code in VAT, you can only edit the comment. To do so, click the company code in the **Company codes** workspace, adjust the comment, and click **Save**.
