Assuming the compensation isn't taxable
What is my adjusted basis, and what is my estimated gain?
Condemnation proceeds are not automatically tax-free. When the compensation exceeds your adjusted tax basis in the property, the difference is generally a capital gain. For investment or business property, it may include depreciation recapture.
Many owners are surprised because the payment feels forced rather than voluntary, but the tax code generally treats it as a disposition of the property.
Section 1033 of the Internal Revenue Code may allow you to defer that gain by reinvesting in qualifying replacement property. It has specific requirements, and how it applies depends on your facts.
