Since 2014, the IRS has been working to move its mammoth system entirely online. Not all of the changes will come with this year's tax filings, but the National Taxpayer Advocate - an independent office within the IRS - predicts that once the new system is implemented, it will increase the cost to taxpayers, and also possibly make them more vulnerable to scams and identity theft.
"I have significant concerns that the IRS is embarking on a path that will unintentionally undermine taxpayer rights rather than enhance them, thereby eroding taxpayer trust further," Nina Olson, National Taxpayer Advocate, wrote in her annual report to Congress for 2015.
