This seventh economic update goes to the heart of one of the main challenges faced by Tanzania: how can the country finance its development? This is a fundamental question when aid is coming down as a proportion of a growing GDP, and as access to financial markets remains limited. Oneoption would be to rely more on the private sector to deliver education, health, roads, ports and electricity. This is possible as demonstrated by many such experiences around the world, and therefore this approach needs to be one important part of the solution to finance development. The argument presented in this economic update is that higher tax revenues will come only if a comprehensive approach is adopted. The tax system has to be affordable, fair, simple, and transparent. The government also has to be accountable for the money it is receiving. It is onlywhen these basic conditions are met that tax compliance will increase. Because a strong social contract between the State and its citizens is not yet sufficiently in place in Tanzania, a number of suggestions are proposed in the update, with the objective of stimulating debate on possibleapproaches to increase tax revenue.
