Our Capacity Development Work
The Fiscal Affairs Department (FAD) provides capacity development (CD) in fiscal policy, including reform design and implementation, sharing knowledge with governments’ fiscal institutions such as ministries of finance and tax and customs administrations, supporting fiscal systems, and strengthening tax and customs institutions' modernization. Strategic advice, as well as hands-on implementation support, peer-to-peer learning, and training are delivered to countries in various ways:
(i) IMF staff and qualified technical experts offer expert advice to country officials both in country and remotely from headquarters; (ii) a network of Regional Capacity Development Centers provides hands-on implementation support to countries under the guidance of headquarters; and (iii) in-person and online training courses are provided for government officials on targeted topics.
