I am not aware of any rule that requires a charity to make public its “budget,” but most charities other than churches and certain other religious organizations are required to give out copies of their Form 990 tax return upon request. (See Ready Reference Page: “Tax Exempts Must Provide Applications, Returns.”) The tax return will show the basic financial data for the year passed, not the budget projected for the year before it began. Most recent 990s are available on the Internet at www.guidestar.org. Many charities are also required to file copies of the tax return and/or audited financial statements in order to solicit contributions in most states. You may be able to get the information you want from the tax return or the financial statement even if you can’t get a budget for the year.
