5500-EZ Penalty Relief Program - taking it back

[TPApril]

After submitting under the 5500EZ Penalty Relief Program, along with check, Plan Sponsor has found their missed 5500 which apparently was filed after all....

Any success getting the application taken back? Can't seem to find a number to call.

Per the rev proc, call the Employee Plans' taxpayer assistance telephone service 1-877-829-5500.  When I have this issue, I get a 2848 and call the same number and have them verify whether they have received a 5500EZ for that plan year.

Not sure if you can "cancel" an application though...
