The primary threshold for Form 8283 is a total deduction of more than 500 dollars for all noncash charitable contributions during the tax year. If your combined noncash donations are 500 dollars or less you typically do not need to file the form, though you still must keep basic records. Once the total deduction exceeds 500 dollars you must complete Section A, providing details such as the type of property, how and when you acquired it, your cost or basis, and its fair market value. When the value of any single item or group of similar items is more than 5,000 dollars, you must obtain a qualified appraisal and complete Section B. If the deduction for one item or group is more than 500,000 dollars, you must also attach the written appraisal to your tax return.
