Receiving an IRS LT16 Notice can feel overwhelming, but it’s essentially an early warning from the IRS. This notice indicates that you either have unpaid taxes, missing tax returns or both. Taking timely action can help you avoid serious consequences like asset seizure or wage garnishment.
This guide explains everything you need to know about the LT16 notice and how to resolve it effectively.
What Is IRS LT16 Notice?
The IRS LT16 Notice is a collection notice sent when the IRS believes:
- You owe outstanding tax debt
- You have unfiled tax returns on record
It is not the final enforcement step, but it signals that the IRS is preparing to take further action if you don’t respond.
Why You Received an LT16 Notice
You may receive this notice for several reasons:
- Failure to file one or more tax returns
- Underreporting income on filed returns
- Unpaid tax balances from previous years
- IRS adjustments increasing your tax liability
Ignoring the notice can escalate the situation quickly.
Potential Consequences If You Ignore LT16
If no action is taken, the IRS may initiate enforcement actions, including:
- Filing a Notice of Federal Tax Lien (affects credit score)
- Wage garnishment or bank levies
- Seizure of assets
- Additional penalties and daily interest charges
What You Should Do If You Receive the IRS LT16 Notice?
1. Review the Notice Carefully
- Check which tax years are involved
- Identify whether the issue is unpaid taxes, missing returns, or both
2. File Missing Tax Returns
- Submit all overdue returns as soon as possible
- Even if you can’t pay, filing helps reduce penalties
3. Pay Your Tax Balance
- Pay the full amount to stop further penalties and interest
- If full payment isn’t possible, pay as much as you can
What If You Can’t Pay in Full?
The IRS offers several relief options:
Installment Agreement (Payment Plan)
- Spread payments over time
- Typically available if you owe less than $50,000
Offer in Compromise (OIC)
- Settle your tax debt for less than the full amount
- Requires proof of financial hardship
Currently Not Collectible (CNC) Status
- Temporary pause on collections
- Used when you cannot afford to pay anything
How to Handle Missing Tax Returns
If your LT16 notice indicates unfiled returns:
- Identify all missing years
- Gather income documents (W-2s, 1099s, etc.)
- File returns promptly
Even if you’re due a refund, you must file within three years to claim it.
Penalties and Interest Explained
The IRS applies:
- Failure-to-file penalties
- Failure-to-pay penalties
- Daily compounded interest
These continue until your balance is fully paid, even if you are on a payment plan.
Can You Dispute an LT16 Notice?
Yes. You have the right to:
- Request a review if you believe the notice is incorrect
- File an appeal through the IRS Office of Appeals
- Submit supporting documentation
Special Situations
You may qualify for additional relief if:
- You are a victim of identity theft
