Frequently Asked Questions
What types of business taxes does a CP161 cover?
A CP161 can cover employment taxes (Form 941/940), excise taxes (Form 720), and other business return types where a balance is due.
Can a business get First Time Abate?
Yes. The business entity is evaluated separately for FTA eligibility. The 3-year compliance history is based on the business EIN, not the individual owner.
What is the Failure to Deposit penalty?
The FTD penalty applies when employment tax deposits are not made on time or in the correct amount. Penalty rates range from 2% to 15% depending on how late the deposit is.

Can the IRS hold business owners personally liable?
For certain trust fund taxes (income tax and FICA withheld from employees), responsible individuals may be assessed the Trust Fund Recovery Penalty (IRC 6672) personally.
How do business installment agreements work?
Businesses can request installment agreements for balances up to $25,000 using the Online Payment Agreement tool. Larger balances may require a Collection Information Statement (Form 433-B).
Will the IRS shut down my business over a CP161?
A CP161 alone will not cause business closure. However, unresolved business tax debts can lead to levies on business accounts and receivables at later stages of collection.
