Answers to common questions

Why did I receive multiple CP 515 notices?
If your business has not filed tax returns, we will send a notice for each tax form and tax period we show as delinquent.

I have never had employees and or filed this return previously so why did I receive a notice requesting me to file?
When you apply for an EIN, we establish filing requirements requiring specific types of returns to be filed (such as Form 940, Employer's Annual Federal Unemployment Tax Return (PDF); Form 941, Employer's Quarterly Federal Tax Return (PDF); Form 1120, U.S. Corporation Income Tax Return (PDF), etc.). When the return is not filed, we consider it delinquent and send a notice requesting filing of the return.

Do I still need to file a tax return even if I had no employees or business activity during the tax period(s) in question?
If you had no employees or business activity during a tax period, you are not required to file a return for that tax period. However, you still must respond to this notice. 

If you made federal tax deposits or other payments or credits for the tax period, you must file a signed return showing the payments to get a refund.

Tips for next year

File all required returns by the appropriate due date.
