ISKCON’s financial life rests on a broad base of devotional support rather than a single institutional source. Temples are sustained primarily through individual donations, offerings placed during worship, and more structured patron or membership programs, including life membership. A significant stream of income comes from the sale of spiritual literature—especially the works of A.C. Bhaktivedanta Swami Prabhupāda and related Vaiṣṇava texts—distributed through temple book tables, street outreach, and affiliated shops. Many centers also operate vegetarian restaurants, cafés, guesthouses, schools, and farm communities, whose modest profits are directed back into temple maintenance and outreach. Festivals such as Janmāṣṭamī, Ratha-yātrā, and other major observances often become focal points for sponsorships and special collections, allowing devotees and friends to underwrite specific aspects of worship, decoration, and feasting. In some regions, ISKCON functions as a registered charity or nonprofit, which can receive tax-deductible donations and, at times, grants for social or food-relief programs.

For those wishing to support this movement, there are both financial and non-financial avenues, each understood as an offering of service (seva). Monetary contributions can be made directly at local temples, through their offices and donation boxes, or via official online portals and bank transfers, often with the option of one-time gifts, recurring monthly support, or participation in patron and life membership schemes. Many devotees choose to sponsor particular services—such as prasadam distribution, deity worship items, festival arrangements, or book distribution—so that their giving is consciously linked to a specific form of devotional activity. Others contribute by purchasing books, devotional items, or food from ISKCON-affiliated outlets, thereby supporting the community while engaging with its teachings and culture. Non-monetary contributions are also deeply valued: volunteering in cooking, cleaning, administration, music, teaching, or professional fields like legal, medical, construction, or IT work, as well as assisting in outreach and book distribution. Those moved to give in kind may offer foodstuffs, flowers, or construction materials, always in coordination with temple authorities, so that the gift harmonizes with the community’s needs and standards.
