The document(s) will be added to the taxpayer’s account (internal DOR system) the next business day. Because you do not need to be logged into a Revenue Online account to submit an e-Filer Attachment, the request will not be shown in Revenue Online.
NOTE: A Login ID and account is NOT created when filing an income tax return through Revenue Online. You must create that separately.
If you are making a payment (by Credit Card or E-Check) and you are unsure if your payment went though (because you did not receive a confirmation number), please don't make a duplicate payment. The confirmation number screen may not display. If you are unsure if your payment went through, you can contact us or log into your Revenue Online account. The payment will appear in a few business days. If you submit a second payment, it will process twice.
You may want to allow a relative or tax professional to view your tax account and manage certain aspects of the account, such as file a return on your behalf or make tax payments. To do that, you must Login to your account and add the "third party" to your account.
This is similar for ceasing Logins.
NOTE: Even if you uncheck an Access Level checkbox for a Login or Third Party that you originally set up for Account Access, the Login ID of the person who, at one time, had access to your account will remain in the listing. But the "Active" checkbox will now be unchecked.
You register only once. There are no passwords for withholding submitters. You will input your own Submitter Information that you will use whether you are submitting withholding files for your own business or as a third party for tax clients. This is a new system and all submitters are required to register at least five days prior to uploading files. The registration process is completed overnight in most cases. However, it may take up to five business days to complete. Third party submitters may register as the submitter and submit as many files as needed using the same Submitter Name. Files with multiple businesses contained in them are also accepted.After your Submitter Name and information are approved, you can use either of these links on the home page after clicking on Submit Year-End Withholding:
For W-2s, the electronic file must be IRS Format 1220 or CDOR-EFW2. The RA record on the file MUST match what you enter as the Submitter Information in Revenue Online.With manual entries (you type them in), you may save your work in Revenue Online and go back later if you are interrupted. When you save, be sure to write down the 6-digit confirmation code so you can go back later in
Again, payers with more than 250 payees must file electronically. Those with fewer than 250 payees may Submit a Manual Withholding File through Revenue Online. If you are unable to submit documents online, CDs are no longer accepted. Please send paper W-2s/1099s/W-2Gs/21-Ws by traceable mail.Note: Paper and electronic withholding documents are due by January 31st.

If you are viewing an account's detail, try clicking on the Home link and see if the service is available at the customer-level.
