The total deduction for charitable contributions in cash to qualified organizations generally cannot be more than 60% (up from 50%) of an individual's AGI for the tax year (20% and 30% limits may apply in certain cases).
Excess contributions that individuals could not deduct in an earlier year because they exceed the limits may be deducted over a 5-year period. Contributions carried over are subject to the same percentage limits in the year to which they are carried. These same rules apply to the new 60% limit on cash charitable contributions made to qualified organizations.
For taxable years beginning after December 31, 2017, no deduction is allowed for any amount paid for the right to purchase tickets for seating at an athletic event in an athletic stadium of an institution of higher learning.
