Proposed regulations under section 475 of the Code set forth an elective safe harbor for dealers in securities and/or commodities and traders in securities and commodities that permits these taxpayers to make an election pursuant to which the values of the positions reported on certain financial statements are the fair market values of those positions. The safe harbor is based upon the principle that if the mark-to-market method used for financial reporting is sufficiently consistent with the mark-to-market method required by section 475, then the values used for financial reporting should be acceptable values for purposes of section 475, even if those values are not fair market values under general tax principles. To ensure minimal divergence from fair market values under tax principles, the regulations impose certain restrictions on the financial accounting methods and statements that are eligible for the safe harbor and may require certain adjustments to values used in the safe harbor. This safe harbor attempts to reduce the compliance burden upon taxpayers and to improve the administrability of valuations for the IRS. A public hearing is scheduled for September 15, 2005.
