I lived in my home for less than 2 years. What are unforeseen circumstances for the exclusion reduction?
As of now, the IRS acknowledges only change of health or a change in the place of your employment. (The IRS has not as yet defined other unforeseen circumstances and does not allow you to claim the exclusion based on unforeseen circumstances until the IRS issues final regulations or appropriate guidance.) Please refer to IRS Publication 523 for additional information (This link requires Adobe® Reader®).
