We discovered an IRS notice after moving offices. Can we assume the response deadline starts when we found it?
Finding an IRS notice late does not automatically restart its deadline.

Finding an IRS notice late does not automatically restart its deadline. The notice type, mailing rules and last-known-address facts determine what options remain. Some deadlines affect court rights and need urgent attention; a general phone call may not preserve them.
A specific business-owner situation
A business discovers a tax notice in forwarded mail after moving. The owner wants to wait until the IRS updates the address before responding, which could lose additional time.
Illustrative example, not a client result.
What to establish before filing
- Preserve the notice and envelope.
- Identify the exact deadline and notice category.
- Seek a timely response or applicable remedy while correcting the address.
Which fact changes the answer?
A routine account inquiry differs from a statutory notice carrying judicial deadlines. Proper mailing and last-known-address facts can be decisive.
A mistake to avoid
Do not assume a deadline runs from the date someone opened the envelope.
Records that support the decision
- Notice and postmark.
- Address-change evidence.
- Return and mailing history.
The decision to document
Escalate deadline review immediately and document any relief or jurisdictional argument separately from the address correction.
