If you meet the definition of “Trader” by the IRS you can choose to use the mark-to-market rules, investors cannot. If a trader doesn’t make a valid mark-to-market election under section 475(f), then he or she must treat the gains and losses from sales of securities as capital gains and losses and report the sales on Schedule D (Form 1040), Capital Gains and Losses and on Form 8949, Sales and Other Dispositions of Capital Assets as appropriate. When reporting on Schedule D, both the limitations on capital losses and the wash sales rules continue to apply. However, if a trader makes a timely mark-to-market election, then he or she can treat the gains and losses from sales of securities as ordinary gains and losses (except for securities held for investment – see above) that must be reported on Part II of Form 4797, Sales of Business Property. Neither the limitations on capital losses nor the wash sale rules apply to traders using the mark-to-market method of accounting.
A trader must make the mark-to-market election by the original due date (not including extensions) of the tax return for the year prior to the year for which the election becomes effective. You can make the election by attaching a statement either to your income tax return if filed without an extension or to a request for an extension of time to file your return. The statement should include the following information:
- That you’re making an election under section 475(f);
- The first tax year for which the election is effective (that is, the tax year for which a timely election is being made); and
- The trade or business for which you’re making the election.
It’s important to note that in general, late section 475(f) elections aren’t allowed.
After making the election to change to the mark-to-market method of accounting, you must change your method of accounting for securities under Revenue Procedure 2019-43PDF, Section 24.01. In addition to making the election, you’ll also be required to file a Form 3115. Non-filing of the Form 3115 mentioned above won’t invalidate a timely and valid election.
If you’ve made a valid election under section 475(f), the only way to stop using mark-to-market accounting for securities is to file an automatic request for revocation under Revenue Procedure 2019-43, Section 24.02. Under that revenue procedure, the request for revocation must be filed by the original due date of the return (without regard to extensions) for the taxable year preceding the year of change (the year of change is the first taxable year the revocation is to be effective). This revocation notification statement must be attached to either that return or if applicable, to a request for extension of time to file that return. Late revocations won’t generally be allowed except in unusual and compelling circumstances.
