The amount of charitable giving you can deduct each year varies based on the type of gift you make, to what type of charitable organization and your annual adjusted gross income. Income tax deductions made to a public charity, or donor advised fund like with Crewe Foundation, are 60% of adjusted gross income (AGI)if you are making a gift of cash. If you are donating an appreciated asset the IRS limits the gift to 30% of AGI.If you are considering making a substantial gift that will exceed either the 60% of AGI in cash or the 30% of AGI in appreciated assets, the IRS will allow you to carry forward any unused deductions for the next subsequent 5 years. This comes in handy, especially when you are donating an appreciated asset that could end up exceeding the 30% of AGI limitation.
