LB&I Programs and Resources

Abusive Tax Shelters and Transactions
The Internal Revenue Service has a comprehensive strategy in place to combat abusive tax shelters and transactions.

Coordinated Issue Papers - LB&I
The IRS works to identify, coordinate, and resolve complex and significant industry wide issues by ensuring uniform application of the law through the issuance of coordinated issue papers. Although these papers are not official pronouncements on the issues, they do set forth the Service's current thinking.

e-file for Large and Mid-Size Corporations
For tax years ending on or after December 31, 2006, corporations that have assets of $10 Million or more are required to electronically file their 1120/1102S income tax returns.  For tax years ending on or after December 31, 2007, foreign corporations with assets of $10 Million or more are required to electronically file their 1120-F income tax returns.

Industry Issue Resolution Program
The Industry Issue Resolution (IIR) Program resolves frequently disputed or burdensome tax issues. IRS solicits suggestions for issues for the program from taxpayers, representatives and associations.

LB&I Industry Director Guidance
LB&I Directives provide industry-related and administrative guidance to LB&I examiners to ensure consistent tax administration. The Directives do not establish Service position on legal issues and are not legal guidance.

Pre-Filing Agreement Program
The Pre-Filing Agreement Program is expected to reduce taxpayer burden and make more effective use of IRS resources by resolving or eliminating tax controversy earlier in the examination process.

Schedule M-3 for Reconciling Book to Tax Income
The Treasury Department and IRS are implementing Schedule M-3, “Net Income (Loss) Reconciliation for Corporations With Total Assets of $10 Million or More”.
