It is likely that everything you contributed to your synagogue is
deductible.
According to the IRS
Publication 526, “Generally, you can deduct contributions of
money or property you make to, or for the use of, a qualified organization. A
contribution is ‘for the use of’ a qualified organization when it is held in a
legally enforceable trust for the qualified organization or in a similar legal
arrangement. The contributions must be
made to a qualified organization and not set aside for use by a specific
person.”
Some
examples of qualified organizations include “c
hurches, a convention or association of churches,
temples, synagogues, mosques, and other religious organizations.”
Charitable contributions are included on Schedule A Itemized
Deductions. In order for the donations
to affect your refund/balance due you must use itemized deductions instead of
the standard deduction.
