I'm single and under 65. The IRS standard deduction is $14,600. Why is TurboTax showing my standard deduction as $13,797? My income is less than $14,600. My income is also less than $13,797. I understand the final outcome is the same, but I'm trying to understand the math behind the difference. If the math is simply to match my income, why is the deduction amount higher?
