Departments and agencies must submit various documentation for the budget process. Unfortunately, there is no consistency as to which documents are made available on their websites and there is no centralized source for most of these documents. Links below go to the agency's main budget page; from there, you will need to review the available documents.
Congressional Budget Justifications (CJs) are often the most useful documents. These provide detailed descriptions of the agency’s programs and their purposes. They also include explanations for proposed changes in the next fiscal year, often focusing on the proposed increase or decrease in spending. CJ's are supposed to be accessible on each agency's website with a standard url of agency.gov/cj (e.g. hhs.gov/cj), and USASpending.gov serves as a centralized list of these links.
