# Managing GCD Master Data

## Overview

A distinction is made between two areas when transmitting the e-balance sheet:

- **GCD**(Global Common Data), which specifies the master data to be transmitted, such as the name of the enterprise, legal form, etc.
- **GAAP**(Generally Accepted Accounting Principles), which represents the taxonomy for the financial data, such as accounts and items of the balance sheet, P&L, etc.

In **Tax Balance**, the data for the GCD area are entered in the **GCD Master Data** workspace.

{% info-box %}
The master data managed here can be pre-filled partially by the [master data import](https://support.lucanet.cloud/en/documentation/income-taxes/tax-balance/master-data-tax-balance/import-master-data-from-income-taxes.md) from **Income Taxes**.

All master data that are not imported from **Income Taxes** must be entered in this step.

In addition, pre-filled data can be changed if necessary.
