Notice CP59

Notice CP59 is the IRS notice that it has no record of a required tax return for a specific year, with a request to file, explain why no return is due, or confirm one was already filed.

Ignoring it can lead to a substitute for return prepared by the IRS with no deductions or basis, followed by assessment and collection.

Why it matters: filing the actual return, even late, almost always produces a lower balance than the IRS’s version. See substitute for return.
