Employers: Upload your W-2 and 1099 forms by January 31, 2026

Tuesday, Jan 6, 2026

South Carolina businesses are required to submit their 2025 W-2 and 1099 forms to the SCDOR by January 31, 2026. Remember, if your business submits 10 or more W-2 or 1099 forms, you’re required to use MyDORWAY, the SCDOR’s free online tax portal.

Because taxpayers should wait until they receive all W-2 and 1099 forms before filing their Individual Income Tax returns, it’s vital that employers submit these documents by January 31. However, in 2025, approximately a quarter of W-2 forms were submitted to the SCDOR after the deadline.

Why should you use MyDORWAY for W-2 and 1099 forms?

You can submit W-2 and 1099 forms for multiple businesses in one file.
MyDORWAY automatically detects file formatting errors, decreasing the chances of submitting an incorrect file to the SCDOR.
You don’t have to wait on mail processing.
You’ll receive a printable confirmation when your submission is received, giving you peace of mind that the SCDOR has your information, and that your submission met formatting standards.
Remember, if your business submits 10 or more W-2 or 1099 forms, you’re required to use MyDORWAY.

If you are filing fewer than 10 W-2 or 1099 forms, you can submit paper forms, though the SCDOR recommends using MyDORWAY—it’s the fastest, easiest, most accurate method. You must include the WH-1612 if filing by paper.

Select the submission method that best suits your business:
- Upload electronic W-2 (or 1099) file is best for employers with many employees and an accounting package with payroll modules that can generate the proper format file.
  - For the EFW2 file format specifications, see Social Security Administration (SSA) Publication No. 42-007 located at ssa.gov.
    For the SCDOR state record format specifications, see the RS-1.
- Upload Manual Excel File is best for employers that have fewer than 30 employees and do not have the ability to generate the proper file format from their accounting package.
Visit dor.sc.gov/w2-upload for more information, including a step-by-step tutorial and file formatting details.

Avoid these common mistakes:

Don’t submit a WH-1612 or paper copies of your W-2 and 1099 forms after filing electronically.
Don’t submit W-2 or 1099 forms by email or web message.
Manual uploading of forms requires you to have Microsoft Excel.
Don’t use hyphens in the “numeric only” fields for SSNs, FEINs and Withholding account numbers.
Only submit 1099 forms that withheld SC income.
Remember to include Carriage Return/Line Feeds (CR/LF) in the file. The SCDOR will not accept files without them.
