"Maintaining the highest possible voluntary compliance rate also helps ensure that taxpayers believe our system is fair," IRS Commissioner Charles Rettig said. "The vast majority of taxpayers strive to pay what they owe on time. Those who do not pay their fair share ultimately shift the tax burden to those people who properly meet their tax obligations. The IRS will continue to direct our resources to help educate taxpayers about the tax requirements under the law while also focusing on pursuing those who skirt their responsibilities."
