Consolidated Sales Tax Returns

If you f​​ile South Carolina Sales Tax Returns for a business with two or more locations, consider using our Consolidated Sales Tax Return option. In one file, you can report the information normally submitted on the State Sales and Use Tax Return (ST-3) and Schedule for Local Taxes (ST-389), for all locations of your business. 

If you ha​​ve multiple businesses, you must use a separate Consolidated Sales Tax Return for each business and its multiple locations.

You must apply before you can use this option. After approval, you will receive access to the Consolidated Sales Tax Return on your MyDORWAY account. Then, you'll submit your monthly returns using the prefilled .xlsx file provided on MyDORWAY.
