Charitable deductions have not reduced taxes owed

[hoofjoy]

My federal taxes due did not reduce after entering detail for total charitable giving; they only reduced barely upon entering other property taxes paid - why

. You get no tax benefit from itemized deductions until all of them added together are more than your standard deduction.
2016 Standard Deduction
Taxpayer under 65, not claimed as a dependent
$6,300 for Single
$12,600 for Married Filing Jointly, or Qualifying Widow(er) with dependent child
$9,300 for Head of Household
$6,300 for Married Filing Separately
For over 65 or blind, add $1,250 for each instance or add
$1,550 each instance if single and not a surviving spouse.

Once your itemized deductions are more than your standard deduction, then you see a tax reduction for additional deductions.
