The Fair Tax Monitor is a tool that identifies the main bottlenecks within fiscal policies and systems and provides strong evidence for advocacy work at both national and international levels. This guide aims to ensure that teams and consultants working with the FTM are informed about the gendered nature of fiscal policies and systems. It provides a framework for understanding the FTM research guidelines through gender lenses, and guidance for conducting a gender analysis as part of FTM research. These will help in identifying the key factors of national fiscal policies and systems that impact on gender equality, and enhance the gender-responsiveness of advocacy work. This guide will also help readers of the FTM national reports to understand the gender analysis aspect of this project, and more broadly the relationship between tax and gender.
