On January 25, 2022, we notified the Director, Return Integrity and Compliance Services, of potential inaccuracies and other areas of concern based on our review of information on www.ChildTaxCredit.gov. For example, the website references Publication 972, Child Tax Credit and Credit for Other Dependents, which the IRS made obsolete for Tax Year 2021, and did not reference thresholds for single or married filing separately taxpayers. We recommended that the IRS review our concerns and share them with the Department of the Treasury to address.
