Since Somaliland is unrecognised, international donors have found it difficult to provide aid. As a result, the government relies mainly upon tax receipts and remittances from the large Somali diaspora, which contribute immensely to Somaliland's economy. Remittances come to Somaliland through money transfer companies, the largest of which is Dahabshiil, one of the few Somali money transfer companies that conform to modern money-transfer regulations. The World Bank estimates that remittances worth approximately US$1 billion reach Somalia annually from émigrés working in the Gulf states, Europe and the United States. Analysts say that Dahabshiil may handle around two-thirds of that figure and as much as half of it reaches Somaliland alone.
