The formulas
- Per individual = $6,000 - 6% x (modified AGI - $75,000, or $150,000 joint), not below zero
- Deduction = per individual x qualified individuals
How it works
Section 151(d)(5)(C) allows an extra $6,000 deduction for each qualified individual who reached age 65 by the end of the year, for taxable years before 2029. The $6,000 amount is cut by 6 percent of the modified AGI that exceeds $75,000, or $150,000 on a joint return.
The statute reduces the $6,000 amount itself, so on a joint return each spouse gets the reduced amount. The deduction requires a Social Security number on the return, and a married taxpayer qualifies only by filing jointly.
