+Tax Balances
+============
+
+This module allows to compute tax balances within a certain date range.
+It depends on date_range module and exposes 'compute' methods that can be called by other modules (like localization ones)
+
+Usage
+=====
+
+Accounting --> Reporting --> Taxes Balance
+
+Select the company, the date range, the target moves and 'open taxes'
