Federal Tax Workbook Updates

While we make every effort to ensure the Federal Tax Workbook is perfect before we go to press each September, there may be times when an error slips through the cracks or new legislation turns a familiar concept on its head. We want to be sure everyone who receives the Federal Tax Workbook has the most up-to-date information to aid in your tax research, so we put together a Workbook Updates/Corrections sheet that’s available for download below. This sheet is added to anytime a change is identified, and we’ll always include the date it was last updated so you know you’re getting the most current version.
