How can you pay taxes to the County AND City, and still save money?  Homeowners typically see savings because of the effects of annexation on four common bills- Property tax, Vehicle tax, Water/Sewer, and Electric/Gas.  The actual financial impact of annexation is unique to each property and household, but the “average” homeowner can save hundreds of dollars a year by annexing into the City of Columbia.  Please try our Annexation Calculator (opens in new window) to see how you are affected!  You can also see a breakdown of how a typical homeowner’s annual taxes and bills change after annexation on our information sheet for homeowners.
