4883C letter is one of the most common types of communications received from the IRS. 4883C does not mean that you have not filed your returns with the IRS. Rather it is sent by the department when you have successfully filed your returns but the department needs further information. This information is sought by the department to verify your identity in order to process your returns accurately.

What to do if you receive 4883C?

• Call the toll-free telephone number at 800-830-5084.
• Have a copy of the 4883C letter you received, a copy of your prior year tax return (if you filed one) and your most recently filed tax return (if you filed one), as well as any supporting documentation for each years return (such as W-2’s, 1099’s, Schedule C, Schedule F, etc.) when you call.

This contact information is only for taxpayers who received Letter 4883C. The toll-free number is for identity verification only. No other tax-related information, including refund status, is available.

Department will continue processing your tax return once your identity is verified and filing of your return is confirmed. If you have filed your return, it takes approximately 9 weeks to process it once your identity is verified.
