Generally speaking, donations from external individual sponsors are not the main source of income for the NS. Occasionally, often as a result of a fundraising campaign or for a specific or regular project, individual donations are received, but they rarely account for a significant part of the budget. However, for the NS of Iran, this represents an important source of income, accounting for 82% of its annual budget. The Dutch NS benefits from the inheritance of author Jenny Smelik by using the fund to administer an award that bears her name. KBBY currently receives financial support from Nami Island Inc. This amount accounts for 100% of their budget. IBBY Ukraine gets 100% of its budget from individual sponsors. IBBY New Zealand gets 50% of its budget from five organizations, four of which are publishing houses. IBBY Serbia receives financial support from two publishing houses and accounts for 75% of its annual budget.
