When is the deadline to challenge my James Island property tax assessment?

James Island property tax challenges follow a deadline set by Charleston County and printed directly on the assessment notice mailed to the property owner, and that window can shift slightly from year to year. Checking the notice itself, or calling the Charleston County assessor's office directly, is the reliable way to confirm the current deadline rather than assuming it matches a prior year. Missing the window usually means waiting for the next assessment cycle to challenge the value.
