NEW! Annual Withholding Reconciliation filing for tax year 2024 is available starting January 3, 2025. For the Annual Reconciliation MW508/W2/1099 key in option, after logging in select the File a Form option from the Online Services menu and select Withholding Reconciliation form 508.
Withholding Tax Filers! Please note that even though the MW508 form is due on 1/31/25, if the form is filed late and all tax has been paid timely throughout the year, no penalties or interest will be charged during this transition to Maryland Tax Connect.
Attention Transmitters for bulk files of W2/1099s: Maryland has started the annual reconciliation to process bulk files of W2/1099/508s. You may see your file status temporarily change from “Accepted” to “Rejected” over the next week. It will change back to “Accepted” status by mid-April or earlier. If you are trying to upload bulk files and receive a reject message of “Transmission Disabled”, please try again by mid-April. All Tax Year 2024 bulk file submissions will be considered timely.
