Submitting files

Mississippi accepts current year and two prior year filings.
State accepts electronic filing W2-C for Corrections. Mississippi requires a copy of the Form W2-C if there is a change in the Mississippi wages and/or withholding. W-2Cs must be submitted in the same format that the original W-2s were submitted in.  The upload file must be in .txt format.

Employers that issue 25 or more W-2s are required to submit those electronically to the DOR. The taxpayer may be subject to penalties if they issue more than 25 W-2s and do not file as required. You can manually enter or upload your W-2s on TAP.  Log into TAP, under “I want To” select the “More” tab and under “Other” select “Submit W2/W2-C Returns”.  All employers, regardless of the number of returns, are encouraged to utilize the system to electronically enter and submit return information. 

Create Your TAP Account To File Electronically.

Use the 8-digit Account ID in the State ID field for W2s.

• To submit files electronically, register for TAP at www.dor.ms.gov.

• If you are a provider, software company or accounting firm that submits W2s or 1099s for clients---but you do not have a Mississippi tax liability---register for TAP; but, do not request or open a tax account.

Any file of W2s or 1099s over 10MB needs to be compressed (zipped).
