   Log in with the user name you set up after receiving your access notification email.
   Follow the steps in the SCDOR Software Developer Portal Instructions to submit all forms.
    Email SoftwareDevelopersForms@dor.sc.gov with any questions.
Failure to follow these guidelines will result in rejection upon receipt and you will need to resubmit.

Layout Requirements
 Forms are designed on a 6x10 grid with 0.5 inch margins on all sides.
 Print all forms in black ink on 20lb unlined white paper size 8.5x11.
   Print voucher forms on the bottom of the page.
   Clearly outline the cutting line at the top of line 45 and include instructions for the taxpayer 
    to properly cut the line.
 Place the 4-digit NACTP code on each form in the top left corner as a replacement for “1350” in 
  line 4, columns 10-13.
   If applicable, place the secondary vendor NACTP code on line 5, columns 10-13, directly 
    below the primary vendor code in line 4.

Review our MeF business rules on the SES to ensure that your product’s implementation will minimize 
rejections. Confirm that the 2D barcode specifications are up to date and that the barcode is easily 
machine-readable.

Software Updates

The SCDOR should be made aware of all software updates to products after the initial approval. This 
two-way communication is important to make sure we stay informed about bug fixes and features 
offered to taxpayers. In turn, we can help communicate these messages to taxpayers when they contact 
us, which provides better service for our mutual customers.

Common Approval Issues

 Review all current specification documents, including those posted to the SES and the SCDOR 
  software developer’s site for our latest requirements and expectations
   Contact us at the earliest opportunity with any questions related to form design, form 
    instructions, line changes, tax law changes, or schema changes so we can explain or 
    correct as needed.
 Review our test cases. Make sure the output from your product has correct calculations, 
  required supplemental schedules, and correct and readable scanlines or barcodes.
 Submit your paper and electronic returns early. Sending test samples early reserves your place in 
  the review queue and ensures adequate time for review prior to filing season.
