Download as PDF Federal Register / Vol. 70, No. 8 / Wednesday, January 12, 2005 / Rules and Regulations the regulations incorporated by reference, special conditions are needed for the Learjet Model 35, 35A, 36, and 36A airplanes modified by ARINC, Inc. These special conditions require that new avionics/electronics and electrical systems that perform critical functions be designed and installed to preclude component damage and interruption of function due to both the direct and indirect effects of HIRF. High-Intensity Radiated Fields (HIRF) With the trend toward increased power levels from ground-based transmitters, and the advent of space and satellite communications, coupled with electronic command and control of the airplane, the immunity of critical avionics/electronics and electrical systems to HIRF must be established. It is not possible to precisely define the HIRF to which the airplane will be exposed in service. There is also uncertainty concerning the effectiveness of airframe shielding for HIRF. Furthermore, coupling of electromagnetic energy to cockpitinstalled equipment through the cockpit window apertures is undefined. Based on surveys and analysis of existing HIRF emitters, an adequate level of protection exists when compliance with the HIRF protection special condition is shown with either paragraph 1 or 2 below: 1. A minimum threat of 100 volts rms (root-mean-square) per meter electric field strength from 10 KHz to 18 GHz. a. The threat must be applied to the system elements and their associated wiring harnesses without the benefit of airframe shielding. b. Demonstration of this level of protection is established through system tests and analysis. 2.

ACTION: Temporary regulations. AGENCY: SUMMARY: This document contains temporary regulations relating to the requirements for filing corporate income tax returns and returns of organizations required to file returns under section 6033 on magnetic media pursuant to section 6011(e) of the Internal Revenue Code. The term magnetic media VerDate jul<14>2003 12:16 Jan 11, 2005 Jkt 205001 includes any magnetic media permitted under applicable regulations, revenue procedures, or publications, including electronic filing. The text of the temporary regulations also serves as the text of the proposed regulations set forth in the notice of proposed rulemaking on this subject in the Proposed Rules section in this issue of the Federal Register. DATES: These regulations are effective January 12, 2005. FOR FURTHER INFORMATION CONTACT: Michael E. Hara, (202) 622–4910 (not a toll-free number). SUPPLEMENTARY INFORMATION: Background Electronic filing of tax returns benefits taxpayers and the IRS by eliminating the manual processing of returns and reducing errors that are more likely to occur during the manual preparation and processing of paper returns. Electronic filing results in faster settling of accounts and better customer service because the time required to process paper returns is eliminated. The error rate for corporate income tax returns filed on Form 1120, ‘‘U.S. Corporation Income Tax Return’’ and Form 1120S, U.S. Income Tax Return for an S Corporation,’’ on paper is approximately 20 percent. Information returns required to be filed under section 6033, which include Form 990, ‘‘Return of Organization Exempt From Income Tax,’’ and Form 990–PF, ‘‘Return of Private Foundation or Section 4947(a)(1) Trust Treated as a Private Foundation,’’ that are filed on paper have an error rate of approximately 35 percent. The error rate for paper returns is due in roughly equal parts to IRS processing errors and taxpayer return preparation mistakes. By contrast, electronically filed returns have an error rate of less than one percent because these returns are subject to screening by the IRS prior to being accepted and are not required to be input manually by the IRS. Furthermore, returns required to be filed pursuant to section 6033 must be made available to the public by both the organization and the IRS pursuant to section 6104. Many state charity regulatory agencies rely on these returns. Requiring these returns to be filed electronically improves the accuracy of the information for both public and regulatory oversight of these organizations. Electronic filing of returns improves taxpayer satisfaction and confidence in the filing process, and may be more cost effective for taxpayers who file electronically. Electronic filing will enable the IRS to review taxpayer PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 submissions expeditiously to reduce audit cycle time and will help the IRS identify emerging trends. In February 2004, the IRS introduced Modernized e-File, a new electronic filing system for corporations required to file Form 1120 or Form 1120S and organizations required to file Form 990. During the development of Modernized e-File, the IRS worked closely with taxpayers and tax professionals to ensure that the new electronic filing system would satisfy their needs. Modernized e-File alleviates the burden of filing massive paper returns, which may be up to 50,000 pages in length. Electronically filed returns are processed upon receipt and, shortly thereafter, an IRS acknowledgment message is generated to inform taxpayers or tax professionals that the return has been accepted or rejected. Error messages for rejected returns identify the reasons the return was rejected and make it easier for the taxpayer or tax professional to correct the errors. Modernized e-File streamlines electronic filing by eliminating the need for paper documents to be mailed to the IRS and enables taxpayers to attach forms and schedules, along with other documents, to the return in Portable Document Format (PDF). Section 6011(e) authorizes the Secretary to prescribe regulations providing the standards for determining which returns must be filed on magnetic media or in other machine-readable form. Section 6011(e)(2) provides that the Secretary may not require any person to file returns on magnetic media unless the person is required to file at least 250 returns during the calendar year. Section 6011(e)(2)(B) requires that the Secretary, prior to issuing regulations requiring these entities to file returns on magnetic media, take into account (among other relevant factors) the ability of the taxpayer to comply at reasonable cost with the requirements of the regulations. The term magnetic media includes any magnetic media permitted under applicable regulations, revenue procedures, or publications, including electronic filing. Recognizing the benefits of electronic filing, Congress enacted section 2001(a) of the IRS Restructuring and Reform Act of 1998, Public Law 105–206, 112 Stat. 727, which states that the policy of Congress is to promote paperless filing, with a long-range goal of providing for the filing of at least 80 percent of all Federal and information returns in electronic form by 2007. The IRS has partnered with taxpayers and tax practitioners in the design of Modernized e-File to minimize burdens E:\FR\FM\12JAR1.SGM 12JAR1
