The biggest line in Chicago’s 2026 budget ordinance is not the police, not the airports, and not any operating department. “Finance General” — the ordinance’s catch-all label for pensions, bond interest, and other citywide obligations — carries $8.19 billion, 44 percent of the $18.67 billion total. The largest actual operating department, the Chicago Police Department at $2.11 billion, is barely a quarter of it. This list ranks the ten largest department labels in the 2026 Budget Ordinance appropriations file, by the amounts the file itself records, from our reading of all sixteen budget ordinances 2011–2026. Two rules carry every entry: these are appropriations — authorizations to spend, not money spent — and the labels are the file’s own, summed exactly as printed. Together the ten cover 93 percent of the citywide total. This page takes no position on what any department should spend.
1. Finance General — $8.19 billion
Not an operating department at all — the ordinance’s catch-all label for citywide obligations, appropriated $8.19 billion, 43.9 percent of the total. Its three largest accounts in 2026 are the city’s contribution to employees’ annuity and benefit funds ($2.58 billion), interest on bonds ($1.01 billion), and payment of bonds ($726.6 million).
2. Chicago Police Department — $2.11 billion
The largest actual operating department: $2.11 billion, 11.3 percent of the citywide total, and about a quarter of the Finance General line above it.
3. Chicago Department of Transportation — $1.84 billion
Appropriated $1.84 billion — 9.8 percent. The total includes grant funds, which the ordinance appropriates alongside local money in the same file.
4. Chicago Department of Aviation — $1.67 billion
O’Hare and Midway, at $1.67 billion. The airports run on their own enterprise funds, and the ordinance appropriates those funds through the same rows as everything else.
5. Chicago Fire Department — $901.7 million
Appropriated $901.7 million — 4.8 percent of the total, and well under half the police line.
6. Department of Water Management — $772.7 million
Another enterprise-fund operation, appropriated $772.7 million through the same ordinance rows as every other label.
7. Department of Family and Support Services — $653.4 million
Appropriated $653.4 million. The label covers the city’s human-services programs, and much of the total arrives as grant funds.
8. Department of Fleet and Facility Management — $503.5 million
The department behind the city’s vehicles and buildings, appropriated $503.5 million.
9. Department of Streets and Sanitation — $349.9 million
Appropriated $349.9 million — 1.9 percent of the citywide total for the department whose name is on the garbage trucks.
10. Chicago Department of Public Health — $335.0 million
Appropriated $335.0 million, 1.8 percent of the total — the last label on this list to clear a third of a billion dollars.
Questions these numbers can answer
What is Chicago’s biggest budget item? By department label in the 2026 appropriations file, Finance General at $8.19 billion — 44 percent of the $18.67 billion total. It is a catch-all for citywide obligations, led by the $2.58 billion pension contribution, not an operating department.
Is this what the city actually spends? No — an appropriation is authority to spend. The ordinance file records what the City Council authorized, fund by fund and line by line; actual spending lands in separate accounting records.
Does the police line include pensions? No. This list sums every 2026 appropriation row carrying each department’s own name in the file, and the city’s pension contributions sit under Finance General — so the police total here is the department-labeled appropriation, not the full cost of policing.

The sixteen-ordinance panel, the department-name drift that makes Finance General the only stable label, and the fund-type breakdown are in the full analysis: One Department Name Survives All Sixteen of Chicago’s Budget Ordinances: Finance General, Now 44 Percent of the Appropriations.
