The 9/11 Memorial Museum is recognized as a qualified charitable organization. Consequently, the fair market value of your donated materials is generally tax deductible. To take advantage of your deduction, you must file tax form 1040 and, depending on the value or estimated value of your donation, tax form 8283. It is recommended that you consult with your own accountant, attorney, and/or the IRS. You may also consult IRS Publication No. 526, Charitable Contributions, and Publication No. 561, Determining the Value of Donated Property.
