Taxpayer can’t prove timely filing with unapproved PDS

You can e-file your Tax Court petition, take your chances by dropping it in the mail or use a private delivery service, like FedEx. But if you choose a PDS, you must be sure it’s on the IRS’ list of approved services. A taxpayer who wasn’t so careful had his petition bounced out of Tax Court and was unable to contest his tax deficiency.
