New Paragraph

Few things cause more anxiety than opening your mailbox and finding a letter from the IRS. For taxpayers in Oklahoma City and across the state, IRS notices are often the first sign that a tax issue has reached a critical stage.


But not all IRS letters mean the same thing. Some are reminders. Others are warnings. And some are immediate threats of enforcement. Knowing what each notice means—and what to do about it—is critical to protecting your finances.


At Summit Tax Relief, we help Oklahomans with $25,000+ in IRS debt interpret notices, respond quickly, and prevent the worst-case scenarios like levies and garnishments.


1. Why the IRS Sends Notices


IRS notices serve several purposes:


Inform you of a balance due.


Request missing returns or documents.


Propose changes to your tax return.


Warn of upcoming collection actions.



Ignoring them only makes the problem worse.


2. Common IRS Notices and What They Mean


CP14 – Balance Due Notice


The first notice you’ll receive if you owe money.


Explains the amount due, interest, and penalties.


Ignoring it triggers additional notices.



CP501, CP502, CP503 – Reminder Notices


Series of increasingly urgent reminders of your unpaid balance.


CP503 is often the last reminder before final action.



CP504 – Final Notice of Intent to Levy


A critical letter.


Warns the IRS will levy wages or bank accounts if you don’t respond.


May also state intent to seize state refunds.



LT11 / Letter 1058 – Final Notice of Intent to Levy & Right to Hearing


The most serious collection notice.


Provides your right to a Collection Due Process (CDP) hearing.


Ignoring this letter almost guarantees levy action.



CP59 – Unfiled Return Request


Notifies you that the IRS has no record of your return.


May lead to Substitute for Return (SFR) filings.



CP2000 – Underreporter Notice


Informs you of discrepancies between your return and IRS records.


Common for 1099s, W-2s, or brokerage accounts.


3. Consequences of Ignoring IRS Notices


Failing to respond leads to:


Wage garnishments.


Bank levies.


Tax liens.


Seizure of assets in extreme cases.



Oklahoma Example:

A client in Oklahoma City ignored CP504 and LT11 letters. Within weeks, his bank accounts were levied for $28,000. Summit negotiated a release and structured an installment plan, but the damage was avoidable.


4. How to Respond to IRS Notices


Read the notice carefully. Each has specific instructions.


Check deadlines. Missing them limits your options.


Gather documentation. W-2s, 1099s, bank records.


Contact Summit. Professional representation ensures you respond correctly and on time.


5. Preventing Notices from Escalating


File returns on time, even if you can’t pay.


Communicate with the IRS proactively.


Enter into resolution agreements before enforcement.



Summit Tax Relief helps Oklahomans turn a stack of intimidating notices into a manageable resolution strategy.


IRS notices are warnings, not death sentences. The key is understanding what they mean and responding before enforcement begins.


If you’ve received IRS letters—and especially if you owe $25,000 or more—Summit Tax Relief can help you interpret, respond, and resolve your tax debt.

Frequently Asked Questions

What is the most serious IRS notice?

The LT11 or Letter 1058 is the most serious. It is the Final Notice of Intent to Levy and provides your right to a hearing before enforcement begins.

What happens if I ignore a CP504 notice?

The IRS can levy your wages or bank accounts, and may seize your state tax refund.

Do IRS notices mean I’m being audited?

Not necessarily. Most notices are about balances due, missing returns, or mismatches—not full audits.

Can Summit Tax Relief respond to IRS notices on my behalf?

Yes. With proper authorization, we handle all IRS communications for Oklahoma taxpayers, ensuring deadlines are met and rights are protected.
