The federal budget seems impenetrable. It isn't.
You've probably seen headlines about continuing resolutions, government shutdowns, or billions in spending—and felt like you were missing context everyone else had. You're not alone. Federal budgeting uses specialized vocabulary, obscure document formats, and processes that even many Hill staffers find confusing.
But here's the thing: the core concepts aren't that complicated. Congress appropriates money. Agencies spend it. There's a paper trail. Once you understand the basics, the rest is just details.
This page is your roadmap. Start anywhere that interests you, or work through it in order.
1. Understanding the Legal Framework
Before diving into appropriations, it helps to understand why federal spending works the way it does. The answer is in the Constitution and a handful of key laws.
The Constitutional and Legal Framework: Laws That Control Federal Spending
Federal budget execution isn't just bureaucratic process—it's constitutional law in action. This post covers the Appropriations Clause, the Antideficiency Act, and the Impoundment Control Act: the legal guardrails that determine what agencies can and can't do with money.
2. Appropriations
This is the core of federal spending: Congress decides how much money agencies get and what they can spend it on.
What is an Appropriation? Understanding Congress's Power of the Purse
The foundational concept. An appropriation is legal authority to spend money—nothing more, nothing less. This post explains what that means and why it matters.
How Appropriations Work: Duration and Distribution
Not all appropriations are created equal. Some money expires after one year; some lasts a decade. This post covers the practical mechanics: how long funding lasts, how it gets divided up, and what happens when it runs out.
3. Tracking Federal Spending
Knowing what Congress appropriated is just the beginning. Tracking whether agencies actually spend the money—and on what—requires understanding the data.
The Three-Legged Stool: Why Federal Budget Tracking Requires Multiple Data Sources
There's no single source of truth for federal spending. Understanding the full picture requires combining appropriations, apportionments, and execution data. This post explains why and introduces the key documents.
The TAFS: The Universal Identifier for Federal Spending
Every federal dollar is tagged with a Treasury Account Fund Symbol. Learn to read these codes and you can trace any appropriation from the bill text to actual spending. This post teaches you how.
4. CRs and Shutdowns
Sometimes the appropriations process breaks down. Congress misses deadlines. Agencies run out of money. Here's what happens next.
How to Read a Continuing Resolution
When Congress can't pass full-year appropriations, they pass a CR. But CRs aren't just "keep spending at last year's levels"—they're full of exceptions, anomalies, and special provisions. This post shows you how to decode them.
What is a Government Shutdown? Understanding Lapses in Appropriations
A shutdown happens when appropriations lapse. But what does that actually mean? Which employees go home? Which programs keep running? This post explains the mechanics.
