Consequences depend on the notice type:
Missed CP14/CP501/CP503 Deadline
- The debt remains and interest continues to accrue
- You will receive an escalated notice (CP503 or CP504)
- You can still arrange payment or payment plan
Missed CP2000 Deadline
- The IRS may issue a statutory notice of deficiency
- Proposed changes may become final
- You may still submit a late response with explanation
- If already final, you may need to file an amended return or pay the assessment
Missed CP504/LT11/CP90 Deadline (CRITICAL)
- Levy action may have already begun or is imminent
- IRS can garnish wages, levy bank accounts, or seize property
- You may have lost your right to a Collection Due Process hearing
- Contact the IRS immediately and engage professional representation
Immediate Actions to Take
Do These Things Today
- Identify the exact notice type and original deadline
- Calculate how many days past the deadline you are
- Call the IRS phone number on the notice immediately

- Submit a written response immediately, referencing the missed deadline

Can You Still Respond After the Deadline?

- Balance Due Notices – You can still pay or request a payment plan at any time
- CP2000 (Income Mismatch) – Late responses may be accepted if you provide reasonable cause for the delay
- Levy Notices – You may request an equivalent hearing or appeal if you have not already received a Collection Due Process hearing
- Audit Notices – Contact immediately to reschedule or explain the missed deadline
Penalty Abatement for Missed Deadlines
If you missed a deadline due to reasonable cause, you may request penalty abatement:
- Serious illness or family emergency
- Death in immediate family
- Natural disaster
- Unavoidable absence
- IRS error or delay
