unlikely. you would have had to pay more than FMV for it. considering that it's to hold a cremation urn you got some benefit. then the church would have to issue you a document showing the amount paid and the fair market value. if you paid more than the FMY, that would be a deduction. nut the IRS could challenge it and if the church plays loosly with issuing donation letters, the IRS could revoke its tax-exempt status. this seems no different than paying for a burial for which a taxpayer does not get a donation deduction.
