Common questions

What's the difference between a CP14 and later notices?

CP14 is typically the first notice of a balance due. CP501 and CP503 are follow-up reminders that generally precede more serious collection action, like a lien or levy notice.

Do I need to act immediately on a first notice?

Acting early generally preserves more options than waiting. An independent tax-resolution professional can review your specific notice and timeline.
