Understanding your 2801C Letter
You received this letter because we determined that you’re not entitled to claim exempt status or more than a specified number of withholding allowances. Generally, your employer bases the amount of withholding for federal income tax on your Form W-4, Employee's Withholding Allowance Certificate. However, we can review whether you are entitled to claim exempt status or a certain number of withholding allowances.
What you need to do
- You can ask us to change our decision. Please call us at the number shown below within 30 days from the date of the letter. We will consider your explanation of why you believe you are entitled to a different withholding rate or number of withholding allowances (or exempt status)
- When you call, have the following information available. If you file jointly, you must have the same information available for your spouse
- Form W-4 and worksheets. (You must complete the "Two Earners Multiple Jobs Worksheet" on the back of the Form W-4, if you have more than one job or your spouse works.)
- Most current pay stubs for all jobs
- Number of withholding allowances you (and your spouse) are claiming on your Form(s) W-4.

Answers to Common Questions
What happens if the IRS determines that I do not have adequate withholding?
We can tell your employer to withhold federal income tax at an increased rate. We do this by issuing a “lock-in letter.” At that point, your employer must disregard any Form W-4 that decreases the amount of your withholding. You’ll receive a copy of the lock-in letter, and we’ll give you some time before the lock-in rate is effective to submit a new Form W-4. This form must include a statement that explains why you believe you’re entitled to a different withholding rate or number of withholding allowances. You should send your Form W-4 and supporting documents to the IRS address as shown on this webpage. Once we issue a lock-in letter, you won’t be able to decrease your withholding unless we approve it.
What if I don’t want to submit a Form W-4 to my employer?
Your employer must withhold income tax from your wages as if you’re single with zero allowances.
