As part of Dorchester County's efforts to place County services at our residents’ fingertips, thus elevating travel time, and in-person office visit. Residents can now register their vehicles online

After the form has been properly submitted and the tax bill is created, it will take an additional 24-hours for the system to update. At that time the personal property taxes for the vehicle can be paid to the Dorchester County Treasurer's Office in one of the following ways:

  • Online, note all convenience fees have been waived until March 31, 2020
  • By Mail to the Dorchester County Treasurer's Office
  • Dropbox at the St. George or Summerville Treasurer's Office.

Note: All County offices are currently closed to the public in an effort to reduce the spread of COVID-19. However, both the Auditor's Office and the Treasurer's Office are available by phone and email during normal business hours. 

Upon payment, the tax receipt will be emailed. The official paid tax receipt will be mailed out to the address on record from the Treasurer’s Office. This official paid tax receipt and the vehicle documentation should be taken to the SCDMV to complete the registration process.


For questions regarding the online form and tax bill please contact the Auditor's Office at (843) 832-0118.

For payment related questions please contact the Dorchester County Treasurer's Office at (843) 832-0165.
