Generally an individual trader must have made the automatically approved election in writing between February 8, 1999 and April 15, 1999  (April 16, 1999 for taxpayers filing with the Andover, MA Service Center).  The written document must have been filed (we suggest traders use certified mail with return-receipt-requested) with the IRS office where the trader normally mails his or her tax filings (attached to form 1040, 4868, 1040X etc.). Special, more liberal rules allowed certain individuals and entities such as S-corporations, Trading Partnerships and Limited Liability Companies to elect Mark-to-Market under less restrictive procedures.

At that time the written election document was not available as an IRS "form" but rather you, your tax preparer or attorney must have used a free-form format. This must have indicated: 1) an appropriate description of the election, 2) the first year that you used Mark-to-Market and 3) the specific trade or business (i.e. Schedule C) for which the election is being made.

When you change your method of accounting for gains and losses to the Mark-to-Market method you must also complete an "Application for Change in Accounting Method" form 3115. The properly completed form is then sent concurrently to both the IRS office where you normally mail your tax returns (along with form 1040) and to the national office of the IRS. The form must be filed between the dates January 1, 2000 and October 16, 2000 (we suggest that you use certified mail with return-receipt-requested).
