Filing and Paying Taxes Online Help

Motor Fuel Ehtanol Producer, Importer/Exporter, LNG, and Supplier licenses and 911 Emergency Surcharge licensees are required to file and pay electronically.

Sales, use or contractors’ excise tax taxpayers may file returns and pay taxes electronically.

EPath is available 24 hours a day, 7 days a week.

Licensees may create an EPath account at any time. After you create your EPath account, the Department will mail you the initial password in 3-5 days.

If you already have an EPath account, you may add licenses with the same ownership to that account as soon as you receive the license number.

You need the following to create an EPath account:

• License number,
• Owner Name or DBA,
• Tax due on the last non-zero return (or a “0” for 911 Emergency Surcharge licenses). If you did not have a non-zero return, please contact the Department to create your account.

If you do not have a tax license, you may create an EPath account when completing your online tax application at: http://sd.gov/taxapp

If you did not apply for EPath at the time of registration, you may create an EPath account at any time after you receive your registration number.

You select your username (minimum of 8 characters) when creating an account. The username selected when creating the EPath account is the EPath administrator and is the only user that can add or edit user accounts.

The initial password is mailed to the licensee’s address. You are required to select a new password when you log in the first time. Passwords may be changed online at any time.

Passwords must be a minimum of 8 characters and must contain at least 1 upper case letter, 1 lower case letter, and 1 non-alphanumeric character (!@#$%^&*()?).

If you forget your password, select “Forgot your Password”. You will need to answer one of the three security questions you set when you signed up. If you are not able to reset the password, please call 1.800.829.9188, to have the password reset.

The administrator can allow multiple people (users) to access the EPath account to file and pay returns by creating a username for each person and selecting the license(s) that person may access.

The new user’s account is given a computer generated password. Be sure to provide that password to the new user. The new user must select their own password, enter their email, and answer their security questions the first time they log in. A user can only see licenses the administrator designates.

The administrator is the only user that can add or edit user accounts. The administrator is the user that created the EPath account.

Only one EPath account is required for an owner that has multiple licenses (all operating under the same FEIN.)

To file returns for multiple licenses under one EPath account, create an EPath account using the license number and name for one of the business locations. When you log in, select Change Profile, then Add License. Enter the license number, owner name or DBA of the business and the tax due on the last non-zero return (or a “0” for 911 Emergency Surcharge licenses). Click Add. Select Assigned Licenses. The license added should show in the Current Licenses list.

When you select File Return or Payment all licenses added should show in the top drop down box. If this does not work, verify that each license has the same FEIN, if so, contact the Department at 1.800.829.9188 to help set up the accounts. IF the licenses do not have the same FEIN, you will need separate EPath accounts for each.

If you wish to file only one 911 Emergency Surcharge return for multiple locations please contact the Department at 1.800.829.9188.
