The responsibility for approving a budget belongs with the Board of Trustees. Each year in September, the Treasurer estimates the coming year's revenue and expenses based on the current year's actual revenue and expenses to date. The Finance Committee consults each World Service Conference Committee chair in advance of the year's Conference and asks for an estimate of costs of upcoming projects stemming from the decisions of the World Service Conference.

The Treasurer then prepares the first draft of the budget and brings it to the Finance Committee. The Finance Committee reviews and revises the first draft as needed and then recommends it to the Board of Trustees. The Board approves the final budget in December, disseminates it to the committees, groups, and intergroups, and publishes it on this website.
