CP2000, CP14, LT11: A Plain-English IRS Notice Decoder

The IRS believes you owe tax. Not an audit. Usually resolves with payment or a payment plan. Has a 21-day window before interest starts accruing differently.

The IRS matched a 1099 or W-2 to your SSN that doesn't appear on your return and is proposing additional tax. This is a proposal, not a bill. You have 30 days to agree, partially agree, or dispute with documentation.

Second-stage collection notice. The IRS can seize your state tax refund and is signaling broader collection action is coming if the balance isn't addressed.

The IRS plans to levy wages or bank accounts in 30 days. Grants the right to a Collection Due Process hearing, which pauses collection if requested in time. Do not ignore this letter.

Proposes audit adjustments after an examination. You have 30 days to respond before the IRS issues a statutory notice of deficiency (90-day letter).

Variants of intent-to-levy notices for specific situations. Treat them with the same urgency as LT11.

A code, a deadline, and a response path. Respond on time, in writing, and you usually keep your options open. Miss the deadline and the IRS's position becomes harder to challenge.
