Artist-Museum Partnership Act of 201 9 This bill allows taxpayers who create literary, musical, artistic, scholarly compositions, or similar property a fair market value (determined at the time of contribution) tax deduction for contributions of such properties, the copyrights thereon, or both, to certain tax-exempt organizations, if such properties are properly appraised and are donated no less than 18 months after their creation. The bill limits the amount of the deduction based upon the donor's artistic adjusted gross income, as defined by this bill.
