A notice is not always an audit conclusion, and forwarding it to the return preparer is not a complete response. The first 72 hours protect the deadline and establish the entity, tax, period, filing and payment facts.
1. Hours 0–12: authenticate and lock the deadlines
Scan the envelope and every page. Record received date, notice date, CP, LTR or state number, entity, EIN, tax, period, amount and response due date. IRS pages explain notices by number, and some appear online, but not every notice is digital. Preserve the paper original.
Verify addresses, phone numbers and account information and avoid unfamiliar payment links. Do not assume a universal 30- or 60-day period; use the actual notice. Some state protest deadlines are jurisdictional, and missing one can make an assessment final and change the available remedy.
- Original, envelope and full scan
- Notice number and official page
- Entity, EIN, tax and period
- Response, payment and appeal dates
- Authenticity and secure payment channel
2. Hours 12–24: assign ownership and legal authorization
Name one case owner and one executive approver; stop departments from calling independently. Include tax, Payroll, accounting, legal and providers on a need-to-know basis. Only the taxpayer or an authorized representative can access protected information. Form 2848 permits an eligible individual to represent the taxpayer for listed matters and periods.
Form 8821 generally authorizes access to or receipt of information but not advocacy before the IRS. Specify entity, return and period instead of an unusable broad scope. States have their own POA rules, so a federal Form 2848 should not be assumed valid for a state case.
- Case owner and executive approver
- Form 2848 or state POA
- Form 8821 information boundary
- Provider and counsel roles
- One external communication channel
3. Hours 24–48: reconstruct the return and account facts
Collect the original return, extension, amendment, e-file acceptance, payment confirmation, account transcript, ledger, supporting schedules and prior correspondence. Compare the agency assertion line by line and test whether a payment used the wrong EIN, period or tax type.
Go beyond the return PDF. A Payroll notice needs Forms 941 and W-2, deposits and registers; Sales Tax needs permits, returns, channel sales and certificates; international reporting needs schedules and filing evidence. Mark each difference agree, disagree, insufficient information or timing.
- Original, extension and amended returns
- Electronic acceptance and payment evidence
- Account transcript and prior notices
- Ledger, subledgers and provider reports
- Itemized fact-difference schedule
4. Hours 48–72: choose the path and protect rights
If the company agrees, follow the notice for payment or documents and determine whether a response form is still required. A disagreement should state facts, authority, indexed support and requested action. IRS guidance emphasizes responding by the due date to protect appeal rights, and state protests must satisfy their stated form and delivery requirements.
A cash shortage does not remove the response obligation. Evaluate undisputed payment, a plan or another procedure without inadvertently surrendering rights. Use tracked mail, retain upload confirmation, and log each call's date, number, employee ID and substance.
- Agree, partially agree or disagree
- Fact statement and exhibit index
- Requested action
- Payment, interest and cash plan
- Mail, upload and call evidence
5. After 72 hours: manage the case instead of waiting
Maintain an issue log with next deadline, expected agency time, open documents, owner and escalation. Keep submission proof with later letters. A new notice can carry its own deadline even when an earlier response remains pending.
At closure, capture the root cause—address, payment period, platform omission, W-2 mismatch, missing certificate or incomplete international schedule—and embed correction in close and filing controls. Notice management should prevent one data defect from repeating across entities and states.
