I missed this last year, but it’s worth knowing about. The usual suspects are exploiting weak security on tax returns; they steal identities, file returns, get refunds. Often targets physicians for obvious reasons — they tend to have large refunds and physician information is notoriously easy to steal from low security licensing databases.
If it were a corporation with this kinds of security weakness they’d be sued out of existence, but we can’t sue the Feds.
The IRS is very slowly rolling out a PIN to include with returns to establish (relative) authenticity. There were arrests in late 2013 but this fraud is only going to grow over the next few years unless the security upgrade is accelerated. That would require serious bipartisan political pressure.
