If you have a casualty and/or theft loss on property used 100% for business, you will report the loss on IRS Form 4684 Casualties and Thefts, in Section B for business property. You will need to enter this through the Business Income topic of the Federal Q&A.

To enter or review business casualty/theft losses:

1. From within your TaxACT return (Online or Desktop) click on the Federal Q&A tab
2. Click Business Income to expand the category and then click Casualty or theft loss from business property
3. Click Add to create a new copy of the form or click Review to review a form already created
4. The program will proceed with the interview questions for you to enter or review the appropriate information

Once this information has been entered, your loss will carry to Line 14 of IRS Form 4797 Sale of Business Property. Your total gain/loss will then be carried to Line 14 of Form 1040.
