How to request a penalty waiver

The fastest, easiest way to request a penalty waiver is using MyDORWAY, our free online tax portal. 

1. Log in to MyDORWAY.
2. On the Accounts tab, scroll to the account that needs a penalty waiver and click More Account Options.
3. On the next screen, click Request a Penalty Waiver to get started.

If you don’t already have a MyDORWAY account, get started at dor.sc.gov/MyDORWAY-signup.

You can also request a penalty waiver by completing the Penalty Waiver Request (C-530) and mailing it to the address listed on the form. You must include any supporting documentation detailing your request when mailing the form to the SCDOR.

​After you've requested a penalty waiver

After the SCDOR has reviewed your request, we will issue you either a Penalty Waiver Request Approval (C-351) or a Penalty Waiver Request Denial (C-344).
