IRS LT16 Notice — What It Means and What To Do
Receiving an IRS LT16 notice can feel overwhelming. This guide explains what the notice means, what the deadlines are, and what options exist for penalty relief.

What This Notice Means

Common Penalties on This Notice
Failure to Pay (FTP)
Failure to File (FTF)
Interest
Potential Levy and Lien Action
First Time Abate (FTA) May Apply
Penalties on LT16 notices are often eligible for First Time Abate relief under IRM 20.1.1.3.6.1. Taxpayers with a clean 3-year compliance history may qualify for full penalty removal.
Underlying FTP and FTF penalties may qualify for First Time Abate. However, addressing the collection action itself requires resolving the balance, not just the penalties.

Frequently Asked Questions
What enforcement actions can the IRS take after an LT16?
The IRS can file a federal tax lien, levy bank accounts, garnish wages, seize assets, and revoke or deny passport applications for seriously delinquent tax debt.
What is a Collection Information Statement?
Form 433-A (for individuals) or Form 433-B (for businesses) is a detailed financial disclosure including income, expenses, assets, and liabilities. The IRS uses it to evaluate payment alternatives.
Can I request Currently Not Collectible status?
If paying the tax debt would create a financial hardship, the IRS may temporarily place your account in Currently Not Collectible (CNC) status. Interest and penalties still accrue, but active collection stops.

How is an LT16 different from an LT11?
An LT11 is a Final Notice of Intent to Levy with CDP hearing rights. An LT16 is a broader notice about unpaid taxes and/or unfiled returns that may or may not include specific levy intent, but signals that enforcement is imminent.
Should I hire a tax professional for an LT16?
Given the enforcement risk and complexity of collection alternatives, many taxpayers benefit from professional representation at this stage, particularly enrolled agents, CPAs, or tax attorneys.
Can I lose my passport over unpaid taxes?
Yes. Under IRC Section 7345, the IRS can certify seriously delinquent tax debt (currently over $62,000) to the State Department, which may deny, revoke, or limit your passport.
