The Internal Revenue Service on Thursday released inflation adjustments for dozens of tax provisions for 2026, alongside changes required by the One Big Beautiful Bill Act, lifting the standard deduction and shifting income thresholds that determine tax bills.
According to the IRS’s notification, the standard deduction will rise to $16,100 for single filers and $32,200 for married couples filing jointly in tax year 2026, with heads of household at $24,150. Under the OBBBA, the 2025 standard deduction is $15,750 for single filers and $31,500 for joint filers, providing a one-year bridge before 2026 indexing takes effect.
