If you are referring to a 5,000 dollar total deduction for Goodwill donations, you can claim that amount if the donated property has a reasonable fair market value and you itemize deductions. Once your noncash contributions exceed 500 dollars you must complete Form 8283. If the value of similar items donated to all organizations exceeds 5,000 dollars, a qualified appraisal is required and you complete Section B of the form. You should maintain detailed records that describe each donation, the items included, their condition, and your valuation method, supported by a receipt from Goodwill. If the phrase instead means a large number of small donations, the same aggregation rules still apply. The IRS focuses on total fair market value and proper substantiation rather than the count of separate drop offs.
