Payment options​

​
 ​Pay on MyDORWAY​

We recommend making payments on MyDORWAY, the SCDOR's free and secure online tax portal.​​

You can make payments by:

  • Credit card (Visa, Mastercard, American Express, Discover)
  • ACH Debit (also known as e-check Electronic Funds Withdrawal)
​
 Pay by ACH Credit

An Automated Clearing House (ACH) credit is when you “push” money from your account to someone else, such as a friend, family, business, or state agency. 

For the SCDOR, you can pay most taxes with an ACH credit:

  • Paying by ACH credit requires the taxpayer to instruct their bank (or financial institution) to originate an ACH transfer to the SCDOR’s bank. ​
  • Apply on MyDOR​WAY​, the SCDOR's free and secure online tax portal, to obtain the required record addenda layout and banking information to complete your transaction. ​
  • Review the SCDOR ACH Credit Instructions​ to learn more.  
 Watch how to request​ ACH credit payment instructions in MyDORWAY​.
 If paying with a paper check, you should know ...
  • ​The SCDOR only accepts paper checks drawn from a United States bank.
  • ​​Paper checks may be converted to a debit (ACH) transaction which will process payments faster, and the payment will show as an electronic payment on bank statements (scanned check images will not show on bank statements).​​​
  • Follow the instructions on your notice or form for mailing instructions.
