Another change: The standard deduction is $14,600 for single filers for the 2024 tax year, up from $13,850 for 2023. The standard deduction for couples filing jointly is $29,200 in 2024, up from $27,700. And more good news for older taxpayers: Joint filers can increase the standard deduction by $1,550 apiece, for a total of $3,100 if both joint filers are 65-plus. In total, a married couple 65 or older would have a standard deduction of $32,300.
