Docking a boat at one of Chicago's municipal harbors just got a lot more expensive. The city's mooring tax, long set at 7% of the docking fee, has jumped to 23.25% for most boat owners under a revenue ordinance that took effect January 1, as Mayor Brandon Johnson moved to raise what's become widely known around the harbors as the “Yacht Tax.”
The increase, first described in Johnson's October 2025 budget rollout, was pitched by the city as a way to bring boat-mooring rates at municipal harbors into alignment with historical rates and the rate of parking, according to the City of Chicago, Mayor's Office. As Bloomberg describes it, the tax is simply a levy boat owners pay the city to dock at municipal harbors, but the size of this particular hike is what's rankled the boating community.
From 7% to Nearly a Quarter of the Fee
Before the change, Chicago's mooring tax sat at 7% of whatever fee a marina or docking facility charged to moor or dock a watercraft, collected by the facility and remitted to the city, according to a local boating-industry page, Playpen Chicago. The new revenue ordinance sets that rate at 23.25% for most taxpayers, with a lower 7% rate preserved for qualifying not-for-profit corporations, per Chicago's Revenue Ordinance.
The ordinance applies broadly: it taxes mooring or docking any watercraft for a fee in a harbor, river, or other body of water within the city's corporate limits or jurisdiction, the same ordinance states. Chicago Harbors, which manages the city's harbor system, notes separately that slip fees are already calculated based on whichever is longer — the slip itself or the boat's overall length — and are paid for the full harbor season. Boaters who live outside Chicago face an additional cost on top of the mooring tax: the harbor system's rates page lists a 20% non-resident surcharge.
A Budget Gap Drove the Decision
Johnson's administration didn't dress up the motivation. The mayor's 2026 budget proposal, unveiled in October 2025, was a $16.6 billion plan aimed at closing an estimated $1.15 billion deficit, the Playpen Chicago report notes. The mooring tax hike was one piece of that puzzle, and the increase in fees is expected to generate about $4.1 million annually for the city, according to the same report.
That same boating-industry page warned the steeper tax could discourage some boaters, particularly those who live outside Chicago, from using the city's harbors at all. Whether that's actually happened hasn't been established.
Life on the Water Keeps Moving
Out on Lake Michigan, the rhythms of Chicago boating culture continue regardless of the new tax rate. Liam Poczatek operates a water taxi service on the lake, and Bloomberg reports his business boomed over Labor Day weekend, when he began his workday around noon and ferried revelers from Navy Pier to party boats anchored in the Gold Coast bay known as the Playpen, where sailboats and cabin cruisers were anchored. Chicago's boating season winds down around Labor Day weekend, Bloomberg notes, while owners face the new mooring tax.
