CP14
read it properlyNotice and demand for payment (IRC § 6303)
Your first bill. Tax has been assessed and it has not been paid.
21 calendar days where the balance is under $100,000; 10 working days at $100,000 or more. Both figures are printed on the notice itself.
If it passes. Interest accrues and a late-payment penalty is added. The account enters the collection stream: CP501, then CP503, then CP504, then the final levy notice.
Why you got it
An assessment posted to your account with a balance outstanding.
What rights it carries
None attach to this notice. You can dispute by phone, ask for an instalment agreement, ask to be placed in currently-not-collectible status, or go to the Taxpayer Advocate Service.
Do you have to respond?
No formal response obligation. Payment or an arrangement is what stops the escalation.
The mistake people make
Ignoring it because the balance is small. This is the notice that starts the cascade — and if the balance grows past the passport threshold, the path that ends with the State Department.
If crypto is why this arrived, the number on it is probably wrong.
Your exchange reports what you sold for and leaves the cost box blank, so any figure the IRS computes from it treats every coin as though it cost you nothing. Rebuild the basis from your own transaction history — free — and see the real number before the deadline above runs out.
