Understanding South Carolina's $39 billion budget dependency
Two out of every three dollars in South Carolina's state budget comes from somewhere other than state taxes. That is not a scandal. It is a structural fact — one that shapes every serious conversation about zero-based budgeting, agency efficiency, and fiscal reform. Before you can argue about what the state should spend, you have to understand where the money actually comes from. This analysis is that map.
South Carolina law requires zero-based budgeting: every appropriation justified from scratch, every dollar defended on its merits. In practice, the budget carries forward its prior-year base and adds from there. Reforming that requires understanding the budget's architecture first.
Every dollar in the South Carolina state budget has a source. Some come from state income taxes, sales taxes, and other revenues that flow into the General Fund — money the legislature controls and can appropriate freely. The rest comes from somewhere else: federal matching grants, tuition and fees at public universities, dedicated revenues like the Education Lottery, federal highway funds, and dozens of other streams. The Appropriations Act tracks all of it, but the public debate almost never distinguishes between them.
That distinction matters enormously for zero-based budgeting. A legislator who wants to "cut 10%" from a given agency needs to know whether those cuts come from state general funds (which they control) or from federal matching dollars (where a state cut can trigger a proportionally larger loss in total funding). The architecture of the budget — who funds what, and under what conditions — is the prerequisite for any serious reform conversation.
All figures are verbatim extractions from South Carolina H.4025, the FY2025-2026 Appropriations Act, processed through the Palmetto ZBB Suite — a line-item budget analysis tool covering all 115 state agencies. Amounts are as enacted. "Other/Non-GF" includes federal grants, tuition, dedicated revenues, and all other non-general-fund appropriations. Federal funds are not separately enumerated in Part IA of H.4025; agency-level characterizations in this analysis are based on known funding structures.
State general funds account for just 33.8% of South Carolina's $39.2 billion budget. The other 66.2% — $25.9 billion — flows from outside the state tax base.
This is not unusual for a Southern state. South Carolina has historically received more in federal funding than its taxpayers contribute in federal taxes — a structural feature of how Medicaid, highway funds, and other federal matching programs are designed. States with lower per-capita incomes tend to draw more in federal matching funds, particularly for Medicaid, where the federal match rate is inversely tied to state income levels.
But "normal" does not mean "simple." The 66% figure obscures three very different kinds of non-general-fund dependency — each with different implications for reform, different degrees of state control, and different risks if the funding landscape changes.
The 66% non-GF share includes three fundamentally different funding relationships — each with distinct political, fiscal, and reform implications.
When people see that South Carolina's budget is 66% "other," the instinct is sometimes to treat that as a single problem — or a single opportunity. It is neither. The $25.9 billion in non-general-fund appropriations comes from at least three structurally distinct sources, each with different rules about how it can be spent, cut, or redirected.
The Department of Health & Human Services administers South Carolina's Medicaid program. Its budget is $11.9 billion — larger than the entire state general fund.
DHHS is not like other state agencies. Its $11.9 billion appropriation is the single largest line in the SC budget — larger than the Departments of Education, Transportation, and Corrections combined. Nineteen cents of every DHHS dollar comes from the state general fund; the other 81 cents — $9.67 billion — comes from federal Medicaid matching funds. That ratio is not a choice the legislature makes each year. It is set by federal formula, tied to South Carolina's per-capita income, and changes only when Congress changes it.
This has an important implication for zero-based budgeting. The $2.27 billion in state general funds that SC appropriates to DHHS is, in effect, the lever that unlocks $9.67 billion in federal matching dollars. Reduce state appropriations to DHHS and the federal match shrinks proportionally. A $100 million state cut to Medicaid does not save $100 million — it eliminates a multiple of that in total program funding, with the difference falling on providers, patients, or both.
This is why Medicaid dominates every serious state budget conversation. It is not that the program is immune to scrutiny — eligibility policy, administrative costs, and program efficiency are all legitimate subjects for ZBB-style review. It is that the lever mechanics are different. Cutting Medicaid state appropriations is not a way to save money; it is a way to reduce a matching program that costs the state 19 cents for every federal dollar it draws.
"DHHS's $9.67 billion in federal matching funds is 37% of all non-GF spending in the state — drawn by $2.27 billion in state appropriations. It is the most consequential ratio in South Carolina's budget."
The Department of Transportation's $2.78 billion budget is 95.6% non-general-fund — the highest dependency ratio of any large agency in the state. This is not inefficiency. It is the fundamental architecture of federal highway finance. The Federal Highway Administration distributes transportation funds to states via formula apportionments; states provide a match (typically 20%) and receive federal funds in return. South Carolina's $123 million in state general fund transportation spending draws $2.65 billion in combined federal and other transportation funds.
DOT is, in this sense, a pass-through institution at scale. The state appropriates a relatively small amount to maintain its federal partnership; the federal funds do the work of building and maintaining the highway network. Any discussion of "cutting DOT" that doesn't engage with the federal match structure is discussing a small fraction of what the agency actually spends.
Clemson ($1.81B, 88% non-GF), USC ($1.62B, 80% non-GF), and MUSC ($981M, 82% non-GF) show high non-GF percentages for a different reason: tuition revenue, research grants, and clinical fees. These are not federal matching relationships in the same sense as Medicaid or highways. They represent institutional revenue-generating capacity. The state's GF appropriations to these universities are supplements — meaningful to the institutions, but not the lever that unlocks a proportional federal match. The risk profile is enrollment and research funding, not Medicaid policy in Washington.
Agencies with >$100M in non-GF appropriations, ranked by non-GF dollar amount
| Agency | Total | Non-GF $ | Non-GF % | |
|---|---|---|---|---|
| Dept of Health & Human Services | $11.9B | $9.67B | 81.0% | |
| Dept of Education | $7.6B | $3.22B | 42.3% | |
| Dept of Transportation | $2.8B | $2.65B | 95.6% | |
| Clemson University | $1.8B | $1.59B | 87.9% | |
| Univ of South Carolina | $1.6B | $1.29B | 79.9% | |
| Medical Univ of SC (MUSC) | $981M | $805M | 82.0% | |
| State Board for Technical Ed. | $817M | $555M | 67.9% | |
| Dept of Social Services | $629M | $290M | 46.2% | |
| Dept of Public Health | $506M | $369M | 72.9% | |
| Dept of Disabilities & Special Needs | $447M | $304M | 68.1% |
The agencies that run almost entirely on state general funds — Corrections, Juvenile Justice, the courts, law enforcement — are also the agencies where ZBB analysis has the clearest mandate and the fewest federal constraints.
The Department of Corrections spends $674 million per year and sources 91.3% of it from state general funds. There is no Medicaid match to optimize, no federal highway apportionment to draw down, no tuition revenue to supplement the appropriation. The state appropriates, and the state spends. The same is true for the Department of Juvenile Justice (88.6% GF), the Judicial Department (85.6% GF), and Prosecution Coordination (85.8% GF). These are institutions that draw their authority and their funding almost entirely from the state.
This creates a paradox at the center of SC budget reform. The agencies where zero-based budgeting has the most direct traction — where legislators can actually change outcomes by changing appropriations — represent a relatively small share of the total budget. Corrections, Juvenile Justice, the courts, and law enforcement together account for roughly $1.5 billion of a $39.2 billion budget. They are the state-funded core. But they are not where the money is.
"The agencies where ZBB has the clearest mandate are also the smallest slice of the budget. The agencies that dominate the total — DHHS, DOT, the universities — operate under funding structures that don't yield to line-item cuts the same way."
Agencies with >80% from state general fund — the "state-funded core"

|---|---|---|---|---|
| Dept of Corrections | $674M | $615M | 91.3% | |
| Dept of Juvenile Justice | $194M | $172M | 88.6% | |
| Prosecution Coordination | $61M | $52M | 85.8% | |
| Judicial Department | $133M | $114M | 85.6% | |
| Dept of Motor Vehicles | $139M | $122M | 87.8% | |

| Commission on Higher Education | $49M | $42M | 86.3% | |
| Dept of Archives & History | $14M | $12M | 89.1% |
South Carolina's ZBB law requires every agency to justify its appropriations from scratch each year. That is the right principle. But applying it uniformly across a budget where 66% of the dollars are not primarily state decisions requires a more precise framework than uniform percentage review.
For the state-funded core — Corrections, Juvenile Justice, the courts — ZBB operates as intended. The state appropriates, the agency spends, and the legislature can meaningfully evaluate whether the spending is justified. Line-by-line review, priority tiers, decision packages: all of it applies cleanly.
For the federal-matching tier — DHHS, DOT, DHEC, DDSN, DSS — ZBB still applies, but the question changes. It is not "how much should the state spend?" but "what state investment is required to maintain federal partnership, and is that partnership producing value?" Administrative efficiency, eligibility policy, program outcomes — these are legitimate ZBB questions. But they are not the same as asking whether the line item should exist.
For the university system — where non-GF revenues are primarily tuition and research — the ZBB question is about state subsidy, not total agency spending. What is the state purchasing with its GF appropriation to Clemson or USC? Is the return — in workforce development, research capacity, and economic activity — commensurate with the investment? That is a meaningful budget question. It just requires knowing that the $219 million SC appropriates to Clemson is a supplement to $1.59 billion in other revenue, not the full picture of what the institution costs or produces.
The Palmetto ZBB Suite processes the full H.4025 appropriations act down to the line-item level for all 115 agencies, flagging federal match requirements on individual line items and generating structured decision packages. The analysis in this piece draws directly from that data. Future editions of the Palmetto Ledger will examine specific agencies — beginning with the state-funded core, where ZBB tools have the most immediate application.
South Carolina cannot zero-base its way to fiscal transformation by treating all 115 agencies the same way. It can make real progress by knowing exactly which agencies run on state money, which ones run on federal matches that multiply state investment, and which ones generate their own revenue. That map — this map — is where serious reform begins.
