Rivera Family is finalizing year-end giving for tax year 2026 and wants to know what actually shows up as a federal itemized deduction when the return is prepared. They are married filing jointly, they expect adjusted gross income of $350,000 for 2026, and they plan to itemize deductions. During 2026 they make three gifts, a $20,000 cash gift to a public charity, a $3,000 charity gala ticket that includes a $600 fair market value dinner benefit, and a gift of long-term appreciated stock to a public charity with fair market value of $50,000 and basis of $20,000. The immediate question is how much of these amounts becomes a charitable contribution deduction on Schedule A, and how much is disallowed by the new 0.5% of AGI floor.
Before we worry about the familiar percentage limits by gift type, the 2026 change that moves the number for many itemizers is that the first slice of annual charitable contributions produces no itemized deduction. For tax year 2026, an itemizer reduces otherwise deductible charitable contributions by 0.5% of AGI, so only contributions above that threshold remain deductible as an itemized deduction under IRC §170. Mechanically, that means we start with AGI on Form 1040, compute the floor, subtract it from the year’s qualifying charitable gifts, and the remainder is what Schedule A can potentially carry as the charitable contributions line, subject to later ordering and percentage limitations that this introduction is not applying yet. To see the flow on the Rivera numbers, work through the floor computation and reduction here:
After the interaction, we have the key driver for 2026 itemizers, which is that a fixed 0.5% of the client’s AGI is the first amount that cannot create a current-year Schedule A charitable deduction.
Before applying the 0.5% floor, we have to decide what counts as a charitable gift in the first place, because payments that buy a benefit are not fully deductible. For the $3,000 gala ticket, the deductible portion is the payment minus the fair market value of goods or services received in return, so the net contribution is $2,400 computed as $3,000 minus $600. Now predict the single number that will be lost to the floor in 2026, then check it against the computation and tie it to the remaining subtotal.
The floor is computed from the Rivera Family’s 2026 AGI.
\text{0.5% floor}=0.005\times\text{AGI}
Next, we group the year’s gifts that are potentially reported as itemized charitable contributions before later lessons apply the ordering rules and the percentage-of-AGI ceilings by category.
| Gift (2026) | Gross amount | Less FMV benefit | Potentially charitable amount |
|---|---|---|---|
| Cash to public charity | $20,000 | $0 | $20,000 |
| Gala ticket (quid pro quo) | $3,000 | $600 | $2,400 |
| LT appreciated stock to public charity | $50,000 | $0 | $50,000 |
| Total before 0.5% floor | $72,400 |
We then apply the $1,750 floor against the year’s contributions in total to get a preliminary deductible subtotal of $70,650 computed as $72,400 minus $1,750, meaning $1,750 is the portion of 2026 giving that does not create a current-year Schedule A deduction solely because of the floor.
Common error Subtracting the floor from each gift separately understates the deduction more than once.
Once we have the high-level number, the practitioner deliverable is not just the Schedule A line, because each gift type needs different support and the 2026 floor creates a recurring tracking item year to year. For an individual return, the core workpapers usually include a client giving summary that ties each gift to its tax characterization and net deductible amount, a substantiation file that keeps the contemporaneous written acknowledgments and quid pro quo disclosures supporting the amounts claimed under IRC §170, and a carryforward tracker that can roll any disallowed amount into the next year if later computations apply percentage limits. Put these Rivera deliverables into the right set of workpapers, then identify which one would break first if the $600 gala benefit were not documented.
