On Dec. 30, the IRS announced it was revamping a long-standing agreement with the online tax preparation industry in which companies offer free filing to people with incomes below certain levels, a category that includes 70% of filers.

The change in what's known as the Free File program came in the wake of multiple ProPublica articles that revealed how the companies in the program steered customers eligible for free filing to their paid offerings. Under the updated agreement, the companies are now prohibited from hiding their Free File webpages from Google searches, and the IRS was allowed to create its own online tax-filing system.
