IRS Notice CP59 - Did not file taxes

I was going to partly reassure you that IRS telephone service has recovered in the past few years (after bit hits from the 08-09 crash and the 11-12 explosion of tax id theft) -- but unfortunately TIGTA's filing season interim report (just out a few weeks ago) says as of March 1 it was back down to 'level of service' 55.6% (calls answered over net attempts) and 'speed of answer' 13 minutes. In a footnote, management blames the shutdown, which doesn't make much sense to me; I'll be interested to look at NTA's report next Jan., because they are usually more skeptical and explain in more detail. FWIW now that Tax Day is past, telephone service will probably improve some, but I don't know if it will be enough to please you.

For an online option you could try Get Transcript Online. They've tightened security after several serious hacking problems, and many people (including me) can't get in at all, but if you can, it can give you an Account Transcript or maybe better a Record of Account for that year. Assuming your SSN and name was first on the return and your wife's second (which IRS calls 'primary' and 'secondary', but don't let that go to your head) RoA should show significant details of your return as posted, the payments they credited/applied and refund sent if any, and any subsequent 'transactions' (mostly identified by arcane codes) that may have been involved in them issuing the notice.
