Appropriation Categories – Funding Type

Appropriation Categories are categories of government funding that group funds into areas of interest. Budget authority from Congress is required to incur obligations and pay costs associated with carrying out an acquisition program. Typically, Congress authorizes expenditures through an appropriations act, which details the authorized uses of the funds and the dollar amounts associated with each appropriation.

Definition: Appropriation Accounts are the specific designation of Federal Government funds as contained in an Appropriations Act passed by Congress and signed into law by President with each account having a unique four-digit code.

Appropriation Categories

There are five (5) major Department of Defense appropriation categories that Congress has established: Research, Development, Test and Evaluation (RDT&E); Procurement; Operation and Maintenance (O&M); Military Personnel (MILPERS); and Military Construction (MILCON). The main appropriation categories and their number designation are listed below:

  • Research, Development, Test, and Evaluation (RDT&E): appropriations fund the efforts performed by contractors and government activities required for the Research and Development (R&D) of equipment, material, computer application software, and its Test and Evaluation (T&E) to include Initial Operational Test and Evaluation (IOT&E) and Live-Fire Test and Evaluation (LFT&E). RDT&E also funds the operation of dedicated R&D installations activities for the conduct of R&D programs.
  • Procurement: appropriations fund those acquisition programs that have been approved for production (to include Low-Rate Initial Production (LRIP) of acquisition objective quantities), and all costs integral and necessary to deliver a useful end item intended for operational use or inventory upon delivery.

Treasury Index Code

Each Military Department and DoD Wide also has a “Treasury Index Code,” which is a two-digit code (21 for Army, 17 for Navy, 57 for Air Force, and 97 for Defense-Wide) that makes the identifying code for a funding account more specific.

Main Acquisition Category Guide

DoD 7000.14-R Volume 2A “Financial Management Regulation (FMR)”: provides general guidance on the formulation and submission of the budget requests to the Office of the Secretary of Defense (OSD). It’s used for a budget review, submission, presentation, and justification to Congress. The guidance for appropriation categories is found in Volume 2A, Chapter 1. The definition from the guidance pertaining to Appropriations is below.

Authorization: The act of setting aside funds for specific government purposes. It is the process by which Congress designates a certain amount of money for a particular agency, program, project, or activity. Appropriations are typically authorized through legislation known as appropriations bills, which specify the amounts and purposes for which funds are allocated.

Appropriations: A provision of legal authority by an act of Congress that permits Federal agencies to incur obligations and to make payments out of the Treasury for specified purposes. An appropriation usually follows the enactment of authorizing legislation. An appropriation act is the most common means of providing budget authority. Appropriations do not represent cash set aside in the Treasury for purposes specified in the appropriation act; they represent limitations of amounts which agencies may obligate during the period specified in the respective appropriation acts.
