CP2000

IRS CP2000 Letter

The IRS proposes changes to your tax return because the income reported by employers, banks, or brokers does not match what you reported.
In plain English: The IRS got different numbers than the ones on your return. This usually means a W-2, 1099, or brokerage statement reported income you forgot to include — or reported it differently. It is a proposal, not a final bill.

CP14

IRS CP14 Letter

The IRS says you owe a balance on your taxes — this is the first notice of an amount due.
In plain English: This is the IRS's first bill. It means your return (or their correction of it) left a balance unpaid. Interest and penalties start growing from the due date, so speed matters.

CP501

IRS CP501 Letter

Reminder that you still have an unpaid balance — the first of a series of reminder notices.
In plain English: This is a nudge, not an escalation. You got a CP14 earlier and the balance is still there. The IRS sends CP501, then CP503, then CP504 — each one more serious.

Questions

Is this legal or tax advice?

No. Letter Decoder explains what your letter says in plain language and cites official IRS sources. For decisions with real consequences, verify with the IRS or a qualified professional. Every explanation links back to the original text.

What happens to my photo?

It's processed to extract the text and then deleted. We don't store your letters. We'll say this loudly on every page because it matters.

Which letters work?

IRS notices first (CP series, Letters 6419/6475), then state tax, insurance, HOA, and collections letters. If we can't confidently explain yours, we say so instead of guessing.

Why $9.99?

Because the anxiety of an unopened IRS letter costs more than ten dollars. One missed deadline can cost hundreds in penalties.
