Income Tax - Standard Deduction - Alteration

HB 411 increases Maryland's standard income tax deduction amounts for 2026 and beyond. It raises the standard deduction to $4,100 for single filers (from $3,350), $8,200 for heads of household or surviving spouses (from $6,700), and $8,200 for married couples filing jointly (from $6,700). The bill also establishes an automatic annual cost-of-living adjustment starting in 2026, tying future increases to inflation as measured by the IRS formula. This directly affects Maryland residents who claim the standard deduction instead of itemizing deductions on their state tax returns.
