Which principle states that all revenue and expenditure should be in a single budget document?

The principle that states that all revenue and expenditure should be included in a single budget document is related to the concept of unity. This principle emphasizes that the budget should provide a comprehensive view of the financial plan, ensuring that all inflows and outflows of funds are reflected together. By consolidating both revenue and expenditure in one document, it promotes transparency and allows stakeholders to understand the full scope of the financial activities of an organization or government entity.

Unity in budgeting helps to ensure that expenditures are directly aligned with the projected income, which aids in effective financial management and decision-making. This comprehensive approach is crucial for accountability and for fostering trust among stakeholders, as it avoids any potential misunderstandings that could arise from segmented financial documents.

The other principles such as annuality, universality, and specification each have their focus: annuality pertains to budgeting for a specified period (usually a fiscal year), universality relates to the assumption that all budget items are included without exceptions, and specification focuses on providing detailed descriptions of each item. However, it is the principle of unity that specifically ties into the requirement for a single, consolidated budget document reflecting all financial aspects.
