What the letter says
The business version of a CP14: a return was processed and the tax, penalty, or interest exceeds what was paid.
Check it
Business balances often come from a missed deposit or an estimated payment credited to the wrong period. Match the notice to your payment records before paying twice.
Payroll balances
If the CP161 is for employment taxes, treat it as urgent. Trust fund recovery penalties can reach owners and officers personally, and the IRS moves faster on payroll than on income tax.
What to gather
- The notice with the period it references
- The business return (941, 940, 1120, 1065) for that period
- Deposit and payment records (EFTPS history)
Write back
