+        Payroll IT Declarations
+        ========================
+
+        This module allows HR and payroll departments to manage and track Income Tax (IT) declarations submitted by employees.
+
+        Features:
+        ---------
+        - Employee-wise tax declaration submission
+        - HR approval workflow for declarations
+        - Category-wise declaration limits (e.g. 80C, HRA, LTA, etc.)
+        - Auto-calculation of eligible deductions
+        - Integration with Odoo Payroll for accurate tax computation
+        - Attach supporting documents (PDFs, images)
+        - Employee self-service through portal
+
+        Built with usability and compliance in mind, this module streamlines the IT declaration process and ensures transparency and efficiency across the organization.
