If your property is involuntarily converted, you might be able to: Get more time to replace it Defer paying tax on any gains Involuntary conversion (or involuntary exchange) is when you: Lose property to circumstances beyond your control—like theft, fire, disaster, government seizure (condemnation) Replace that property with other property or money—like an insurance payment or condemnation award Why request an extension You have a set time to replace the lost property. To determine the replacement period, use Casualties, Disasters and Thefts, Publication 547. If you can’t replace it within the replacement period, you can request more time if you can show a reasonable cause. For example, new construction won’t be finished within the replacement period. High market value and lack of available replacement properties aren’t reasons for an extension. How to request an extension You can request a replacement period extension of up to a year.
