To review or modify the Form 4684 entries in your TaxAct® return:
TaxAct will use the higher of your itemized deductions or the standard deduction for your filing status to maximize your tax benefit. If you do not itemize deductions, you cannot deduct casualty and theft losses and Form 4684 will not print with your return. However, you can separately print the form to review the calculations.
See the IRS Instructions for Form 4684 for additional information. For certain exceptions and lists of deductible and nondeductible losses, see IRS Publication 547 Casualties, Disasters, and Thefts.
