When a taxpayer cannot meet basic living expenses and pay a current tax debt, the IRS may temporarily delay collection by placing the account in Currently Not Collectible status. Most collection activities suspend, but the debt remains, and interest and penalties continue to accrue. A federal tax lien may still be filed, and refunds may be applied to the balance. CNC is not forgiveness or a fixed pause; the IRS may review finances and resume collection if ability to pay improves. Preparing a CNC financial review means gathering current evidence of hardship, separating known facts from assumptions, and flagging missing proof before professional signoff.
Current Evidence and Verification
The IRS may request Form 433-F, Form 433-A or Form 433-B along with documents verifying income, expenses, accounts and assets. The exact form depends on taxpayer type and current case route. Build a traceable record for each line: the source, date, period and any discrepancy. If an account balance is zero or a field is not applicable, state it explicitly rather than leaving it blank. When information is missing—an unsigned lease, an unlisted account, or an undocumented medical expense—log it in a separate unresolved queue. Refresh the evidence date before submission; a six-month-old bank statement or pay stub weakens the hardship case.
Ability-to-Pay Questions and Standards
A CNC determination is an IRS case-specific hardship finding rather than a mechanical monthly-cash comparison; the IRS may request financial statements covering assets as well as income and expenses, and may ask for Form 433-F, 433-A or 433-B. National standards apply to food, clothing, household items and out-of-pocket health care; local standards govern housing, utilities and transportation. National food and clothing allowances are generally accepted without questioning actual spending, but local housing and transportation treatment typically uses actual expense or the applicable standard, whichever is lower. Do not apply a blanket lower-of-actual rule to every category. When actual expenses exceed standards due to documented medical conditions, disabled family members or other circumstances, the IRS may allow the higher amount with supporting evidence. Frame expense recommendations as editorial judgment, not IRS mandates. Refer to the IRS collection financial standards review for category distinctions and version tracking.
CNC Review Memo: Separate Evidence from Conclusion
| Field | Example Entry |
|---|---|
| Evidence date | 2026-09-15 |
| Income verified | Pay stubs Jan–Sep 2026; spouse unemployed |
| Necessary expenses | Housing lease, utility bills, vehicle loan statement |
| Missing proof | Health-care receipts, insurance premium invoice |
| Open question | Can client shift utility account to different period? |
| Status check | Transcript reviewed 2026-10-01; no lien filed |
This memo separates what you know from what you infer. It surfaces missing proof early, shows the client or manager where assumptions sit, and preserves a clear record for status verification or future review. Do not fabricate annual review schedules or countdown periods; CNC status has no fixed expiration, and the IRS may request updated information at any time.
Workflow Checklist
- [ ] Pull current account transcript and confirm debt, lien status and compliance
- [ ] Identify the form route—433-F, 433-A or 433-B—based on taxpayer type and IRS request
- [ ] Reconcile each income and expense line to a dated source; flag zero, N/A and unknown separately
- [ ] Compare actual expenses to current national and local standards; document exceptions with evidence
- [ ] Log missing proof and open questions in a distinct unresolved queue
If the case may later pivot to an installment agreement or offer, consider how the evidence will translate. Compare financial options through the offer in compromise vs installment agreement review, and distinguish CNC from both settlement and payment-plan routes.
Software and Sourced Workpapers
Building a CNC review memo by hand in spreadsheets or word processors risks version drift, undocumented assumptions and lost evidence links. When evaluating tax resolution software, test the vendor's ability to capture source provenance, flag missing proof, and route a CNC package without overwriting plain 433-A or offer workpapers. The 26T1 Income & Expense Worksheet is marked “Coming next” and describes planned collaborative financial collection and reviewed totals for professional resolution planning; demo questions should verify how the tool handles evidence dates, unresolved fields and standards version tracking. A reusable professional workpaper is not an IRS-accepted submission, and no software guarantees CNC approval or collection suspension.
For detailed guidance on preparing the 433-F financial snapshot, see Form 433-F: Reconcile the Financial Snapshot. When self-employment or business entities are involved, review Form 433-A: Build Reviewable Financial Workpapers or Form 433-B: Keep Business Financial Evidence Clear to keep entity and owner records separate.
What happens to interest and penalties during CNC status?
Interest and penalties continue to accrue on the unpaid balance. CNC suspends most collection activities but does not pause statutory interest or stop the debt from growing.
Does CNC status expire after a fixed period?
No. The IRS may review finances at any time and resume collection if ability to pay improves. There is no universal annual review schedule or automatic expiration date.
Can the IRS still file a lien or offset a refund while an account is in CNC?
Yes. A federal tax lien may be filed, and refunds may be applied to the outstanding debt even when the account is in Currently Not Collectible status.
