The Internal Revenue Bulletin is produced and published by the Internal Revenue Service and contains IRS pronouncements affecting tax analysis under the Code and the Regulations, including but not limited to Revenue Procedures, Revenue Rulings, Notices and Announcements. Access the IRS site at https://www.irs.gov/help/irsgov-accessibility for information concerning accessibility of IRS materials. While every effort has been made to ensure that the IRB database files available through the TouchTax application are accurate, those using TouchTax for legal research should verify their results against the printed versions of the IRBs available from the IRS.
