If you are reporting a Reportable Transaction Number on Line 1c (Reportable transaction or tax shelter registration number) on Form 8886, you may experience problems when trying to submit your return due to Line 1c of Form 8886 (electronic version) having character limitations of 9-11 characters whereas the Reportable Transaction Number (RTN) you were provided exceeds those limitations. We apologize for this inconvenience and ask that you take the following step(s) as a temporary workaround.
