What is the deadline to appeal a Johns Island property tax assessment?

Johns Island property tax appeals run on a deadline Charleston County sets each year and prints directly on the owner's assessment notice. Because Johns Island covers such a wide range of property types and sizes, confirming the current deadline directly with the assessor's office is more reliable than assuming a general rule of thumb. Missing that window typically means waiting for the next assessment cycle to appeal. Brian Beatty can help a Johns Island homeowner gather comparable sales evidence while that window is still open.
