real property value only. See SC Code Section 12-60-90 for more information.

      based on the accounting closing date. The purchaser is not required to file a return as of the

● Amended Return: Filed to correct a previously-filed return. A three-year statute of limitations

  status�

Additional Forms

Application for Five-Year Exemption

Change in Ownership

The purchaser of an existing facility is required to obtain approval from the local county governing body 
for an extension of the five-year partial exemption. The purchaser must submit a completed PT-444, 
Five Year Exemption Extended To Unrelated Purchaser, to the SCDOR within the time stated by law 
for applying for exemption for the existing facility that has been purchased. The PT-444 is available at     
dor.sc.gov/forms� 

New investments in real and/or personal property made after the purchase of the existing facility 
may qualify for the exemption as an addition. This may require the filing of separate schedules for the 
purchase of the existing facility and the additions. Separate schedules will only be necessary if the 
county governing body denies your request for the extension of the five-year exemption. You must 
file an application for exemption within three years of your timely-filed PT-300. For more information 
regarding changes in ownership, see SC Code Sections 12-37-220(C), 12-37-220(A)(7), 12-4-720(A)(1), 
and 12-54-85(F)(1). 

Do not wait for the PT-444 to be accepted before filing your PT-300. 

No Change in Ownership
Owners of existing facilities that have not been purchased within this reporting period are not required 
to obtain approval from the local county governing body. The PT-300 and applicable schedules filed 
within the time prescribed by law for filing an application for exemption is considered your application 
for the partial exemption under SC Code Sections 12-37-220(A) (7),(A)(8), (B)(32), and (B)(34).

Application for Warehousing and Wholesale Distribution
