taxmap/pubs/p225-031.htm#en_us_publink1000218226You can elect, for any class of property, not to deduct the special depreciation allowance for all property in such class placed in service during the tax year. To make the election, attach a statement to your return indicating the class of property for which you are making the
election.
Generally, you must make the election on a timely filed tax return (including extensions) for the year in which you place the property in service. However, if you timely filed your return for the year without making the election, you still can make the election by filing an amended return within 6 months of the due date of the original return (not including extensions). Attach the election statement to the amended return. On the amended return, write "Filed pursuant to section
301.9100-2."
Once made, the election may not be revoked without IRS consent.
 | If you elect not to have the special depreciation allowance apply, the property may be subject to an alternative minimum tax adjustment for
depreciation. |
