Annual Withholding Reconciliation

Revenue Online provides employers/payers with a simple and secure method for filing year-end W-2, 1099 and/or W2-G statements. NOTE: Employers or tax professionals who want to pay withholding tax by Electronic Funds Transfer may continue to make payments using EFT. However, the annual reconciliation must be filed, and using Revenue Online to do that is highly recommended.  If paying additional tax or requesting a refund, submit the DR 1093 for W-2 withholding or the DR 1106 or 1099 withholding.

GETTING STARTED WITH REVENUE ONLINE

Step 1: Register to be a Withholding Submitter

Anyone who is going to submit W-2s, 1099s, or W-2Gs– whether a tax professional, tax service provider and/or a person who does the payroll at the business – must register. To register, go to Revenue Online at least five days before you plan to submit the file or type each W-2, 1099, or W-2G entry.
 

  1. Click on the link Request Withholding Submitter Access.

  2. Complete the requested fields.

A Confirmation will then pop up to confirm that the department has received the registration request.In most cases, the registration process is completed overnight; however, it may take up to five business days to complete. 
 

When you have completed the registration process, you do not need to do it again. Each year when you submit your W-2s, 1099s, or W-2Gs in Revenue Online, you will use Step 2 and Step 3.

Step 2: Decide how you will report the year-end withholding statements

After you are signed up to be a Withholding Submitter in Revenue Online, the following are options for reporting year-end information. The options are divided by wage withholding and 1099/W-2G withholding.

Important Note:
If you have more than 250 employees (W-2) or more than 250 recipients of 1099s/W-2Gs, you must use one of the two reporting methods above.

Paper year-end statements

Although not recommended, employers or 1099 payers may submit paper statements along with DR 1093 or DR1106 if they have fewer than 250 employees/payees. However, the department encourages businesses or their tax providers to register in Revenue Online as a Withholding Submitter and use Revenue Online to report W-2 and 1099 annual reconciliation and submit reconciliation statements.
