Overview
The South Carolina Department of Revenue (SCDOR) offers an electronic bulk filing option for
withholding tax returns WH1605 and WH1606 through the Batch Withholding Program. The SCDOR’s
Batch Withholding Program is available through MyDORWAY, our free online tax portal. MyDORWAY
allows qualified Batch Withholding Preparers to:
●	 Apply to become a Batch Withholding Preparer
●	 Upload Batch Withholding return files and backup reports at the same time
●	 See file validation errors right away
●	 Receive file processed confirmation immediately
●	 Make bulk ACH Debit payments
●	 Access batch file and backup report submissions
●	 Meet the Electronic Filing Mandate requirements
●	 The WH1615 Transmittal is no longer required

Program Qualifications
You must meet the following requirements to participate in the program:
●	 File 10 or more South Carolina Withholding returns per tax period
●	 Have MyDORWAY access
●	 Be registered with the SCDOR
■	 Even if you do not have a South Carolina filing requirement, you can register as a tax preparer
with no business tax accounts with the SCDOR.
♦	 Examples of this include out of state third party payroll service providers or preparers
with no South Carolina nexus.
■	 Details on registering and signing up for MyDORWAY are provided in the Getting Started
section on page 2.

Electronic Filing Mandate
Preparers who file 100 or more returns for a tax period for the same year are required to file all returns
electronically (SC Code Section 12-54-250(F)(1)). If you fail to comply, you may be penalized $50 for
each return.

SCDOR | WH405 Batch Withholding Guide

Identification Number Requirements
Correct FEINs and SCDOR Withholding file numbers for each client are required in order to successfully
submit a batch withholding file. Incorrect FEINs and SCDOR Withholding file numbers will cause your
file to be rejected. This information is also part of the data needed to create the backup report that
must be attached to upload your file. Additional details are provided in the following sections of this
guide.

Getting Started
Business Tax Registration
You must be registered with the SCDOR before you can apply to become a Batch Withholding
Preparer. In-state and out-of-state businesses or preparers can take advantage of the SCDOR’s online
MyDORWAY Business Tax Application at dor.sc.gov/register to get registered.
To complete your registration application, you will need to provide your organization’s:
●	 ​Valid ID number (SSN or FEIN) 
●	 Valid address (physical and mailing​)​
●	 Business structure​
●	 Owner and officer information
●	 Valid email address​
As part of the registration process, all registration types will be prompted to create a logon for
MyDORWAY.	
If you are an out of state tax preparer with no business accounts with the SCDOR, you will be assigned
Third Party Access in MyDORWAY during your registration process. Third Party Access requires you to
add at least one of your South Carolina clients while setting up your MyDORWAY logon. You do not have
to add all clients. Adding one client grants you the necessary access to apply to the Batch Withholding
program.
To complete your Third Party Access, you will need to provide one client’s:
●	 Valid ID number (FEIN, SSN, SID, or ITIN) 
●	 Legal or last name
●	 South Carolina Withholding File Number
●	 Last payment amount, Letter ID, Line 1 from their last return, or the last Withholding payment
made on their account
If you already have a business account registration but do not have MyDORWAY access, visit
dor.sc.gov/mydorway-signup.

Preparing Batch Withholding Files
Data Requirements
The data included in the batch file will be validated at the time the file is uploaded. Each file must
meet the data requirements outlined in the Technical Specifications section on page 5. Batch files must
be submitted in .txt format. Other file types will cause the file to be rejected. Additionally, if the file
includes invalid FEIN or SCDOR Withholding file numbers the entire file will be rejected. All FEIN and
SCDOR Withholding file numbers will include nine-digits. The invalid numbers must be corrected or
removed before a file may be uploaded.
It is the responsibility of the preparer to get correct FEINs from their clients. The SCDOR provides a
Withholding File Number Search tool in MyDORWAY at dor.sc.gov/withholding-search to validate
Withholding File Numbers. Preparers must have the company name and FEIN for their client to use the
lookup tool.

Filing Requirements
WH1605 returns and WH1606 returns must be submitted in separate files. Original and amended
returns of the same return type can be included in the same file. There are 2 return types:
●	 WH1605 – used for First, Second, and Third Quarters (Q1-Q3)
●	 WH1606 – used for the Fourth Quarter only (Q4)
3

SCDOR | WH405 Batch Withholding Guide

Submit only one file and backup report per day for each return type (WH1605 or WH1606). Do not
send separate batch files and backup reports for each client. The program is designed to allow you to
include bulk returns for your clients within one file and backup report.
The file name must contain the Batch Filer Company Name and the Submitted Date (MMDDYYYY),
with no spaces.
●	 File Name Example: CompanyName06252024
A description is also required. The description should include the quarter the file covers. If the file
covers multiple quarters, list the various quarters in the description.
●	 Description Example: Q22024 or Q42023, Q12023, Q22024

Backup Report Requirements
A batch backup report is required as part of your Batch Withholding Return File upload. The backup
report is created by the preparer using one of the following formats: .xls, .xlsx, .csv, or .pdf
The backup report must be searchable or in a sequential Withholding file number order and include the
five items listed below:
1.	 SCDOR Withholding Tax file number
2.	 FEIN
3.	 Business name
4.	 Total tax withheld
5.	 Total payments
You will not be able to submit your file until the backup report has also been uploaded. Backup reports
and files are a one-to-one match. You cannot submit multiple backup reports with only one file or vice
versa. Backup reports will be subject to review to ensure the required data has been provided.
The file name must contain the Batch Filer Company Name and the Submitted Date (MMDDYYYY),
with no spaces.
■	 Backup Report Name Example: CompanyName06252024
A description is also required. The description should include the quarter the file covers. If the file
covers multiple quarters, list the various quarters in the description.

Description

The SA record identifies the organization reporting the
Withholding Tax Returns to SCDOR. This record can appear
only once on the reporting file and it must be the first
record.
The SE record identifies the Employers Withholding Tax
Return (tax data for the reporting period). An SE record
must be present for each employer account for the
period reported. While multiple SE records can appear on

issued. All money fields in this record must include dollars
and cents with an implied decimal and must be rightjustified and zero-filled.
The ST record contains the aggregate totals for all tax data
reported in the SE records. It must be the last record on

and cents with an implied decimal and must be rightjustified and zero-filled.

Error Information
Batch Return File Errors
MyDORWAY validates the file once added as an attachment within the upload process. You will be
presented with any errors identified. If errors exist in your file, you will not be able to move forward
with the upload process.
MyDORWAY provides specific and detailed error messages that are designed to clearly explain what you
need to correct. You will receive a pop-up notification if errors are present. Generally, errors are also
presented in a more expansive error list once the pop-up window is closed. To view the error list, click
OK to close your pop-up notification and scroll to the bottom of the screen.
●	 A description of the error and the line number of its location in your text file is displayed for
each error.
●	 You can export the error list by selecting the Export link.
●	 The error list allows you to delete rows as you correct your file.
●	 Upload the file again once your corrections are made.

FEIN and File Number Errors
●	 Invalid FEIN errors mean the FEIN is not registered with the SCDOR. You will need to check with
your client to determine if the entity needs to be registered under the FEIN they have provided
you with.
●	 Invalid file number errors mean one of the following:
♦	 The file number is not registered with the SCDOR.
♦	 The file number is for a tax type that is not Withholding Tax.
♦	 The file number is not assigned to the FEIN used in the file.
Need a file number? We can help:
To assist you with locating valid SCDOR file numbers, the SCDOR provides a Withholding File Number
Search tool in MyDORWAY at dor.sc.gov/withholding-search to validate Withholding File Numbers.
Preparers must have the company name and last four digits of their client’s FEIN to use the lookup tool.
Common Errors to Avoid
●	 Using FEINs that have not been registered with the SCDOR.
●	 Using file numbers that are not for Withholding Tax accounts.
●	 Using file numbers that are not assigned to the FEIN used in the file.
●	 Using the FEIN as the Withholding file number.
●	 Using a dash in the FEIN or the Withholding file number.
●	 Using “Applied For” in the file in place of the FEIN or the Withholding file number.
●	 Using negative numbers for any field.
●	 Using the incorrect format for the file. The Batch Withholding return file must be submitted
using .txt format.

Backup Report Errors
Backup report errors will keep you from completing the file upload process. The backup report will
generate an error for the following reasons:
●	 The same backup report was used for a previous upload.
●	 The backup report is not in an allowed format. Text files are not supported for backup reports.
Backup reports must be in one of the following formats: .xls, .xlsx, .csv, or .pdf

Payment Options
The Batch Withholding Program offers a bulk eFiling option for returns only. While payments cannot
be made as part of your return filing, several different payment options are available for participants to
initiate separately. There are 4 types of payments that can be made alongside this program:
1.	 MyDORWAY Bulk Withholding ACH Debit
■	 This option allows a preparer to make ACH Debit payments for multiple clients when the
banking account information is the same for all payments.
