+Localization overview
+=====================
+
+The Omani localization package provides the necessary accounting setup for companies operating in
+Oman, including a pre-configured chart of accounts, taxes, fiscal positions, and a standard tax
+report format. It ensures alignment with Oman VAT regulations and Royal Decree requirements.
+
+The Omani localization package provides the following key features to ensure compliance with local
+fiscal and accounting regulations:
+
+- :ref:`Chart of Accounts <localizations/oman/chart-of-accounts>`: based on Omani standards, with
+  mapped account groups and default account mappings.
+- :ref:`Taxes <localizations/oman/taxes>`: standard 5% VAT, zero-rated domestic as well as exports,
+  exempt, imports, and reverse charge taxes.
+- :doc:`Fiscal Positions <../accounting/taxes/fiscal_positions>`: automated tax adjustments based
+  on customer or supplier registration status.
+- :ref:`Tax Report <localizations/oman/tax-report>`: structured according to the Oman VAT return
+  format, as issued by the Tax Authority.

+accounts. Use the :ref:`predefined structure <chart-of-account/create>` or create new accounts, as
+needed.
+
+.. note::
+   Accounts are grouped under relevant categories such as assets, liabilities, income, and expenses
+   in line with local standards.
