(CNN) High-income taxpayers who have failed to file one or more tax returns in the past may be getting a knock on their door from the Internal Revenue Service.

After increasing its enforcement ranks , the IRS announced it will be conducting more face-to-face visits with high-income taxpayers as part of an effort to ensure compliance and fairness across all income groups. The effort will focus on people with income of more than $100,000 a year who did not file their returns for 2018 or prior.

The IRS said the effort is intended as a reminder that everyone must meet their tax obligations and to bring tax cheats into compliance.

The agency said its focus will be on people who have not filed at all over taxpayers who tried to file and pay in a timely way or who have already entered into agreements to pay their taxes.

"The IRS is committed to fairness in the tax system, and we want to remind people across all income categories that they need to file their taxes," said Paul Mamo, the director of collection operations in the small business and self employed division in a statement. "We want to ensure taxpayers know their options to get right with their taxes and avoid bigger issues later."
