Tax season is upon us and the IRS estimates 250 million tax returns will be filed in 2018. Tax filers can generally be broken into two groups: those who use a digital tax service to efile on their own and those who enlist the help of a tax professional.

Thousands of tax service locations pop-up in the months preceding April 15th. HR Block, for example, opened 10,000 locations nationwide for the 2018 tax season. The locations were strategically selected and placed within five miles of 95% of Americans. Jackson Hewitt partnered with Wal-Mart to open 3,000 in-store locations offering free and low-cost tax services.

However, a substantial number of individuals e-file their taxes without the assistance of a tax professional. In 2017, 51.8 million taxpayers prepared and efiled their federal tax returns themselves.
