The new tax rules for 2026 bring significant updates for U.S. taxpayers, largely shaped by the One Big Beautiful Bill Act (OBBBA), signed into law in 2025. This legislation made many provisions from the 2017 Tax Cuts and Jobs Act (TCJA) permanent, averting scheduled expirations and rate increases that would have taken effect after 2025. It also introduced inflation adjustments and targeted changes to ease burdens for families, workers, and seniors.
One of the most noticeable shifts is the increased standard deduction, which reduces taxable income for those who don't itemize. For tax year 2026 (returns filed in 2027), it rises to $16,100 for single filers and married filing separately, $32,200 for married filing jointly, and $24,150 for heads of household. This modest bump from 2025 levels reflects inflation adjustments and helps more people avoid itemizing.
The federal income tax brackets and rates remain the same as recent years, with seven progressive rates: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The top 37% rate applies to single filers over approximately $640,600 (and higher thresholds for joint filers). By making the TCJA structure permanent, the OBBBA prevents a reversion to higher pre-2018 rates.
Other key changes effective in 2026 include a new above-the-line deduction for cash charitable contributions—even for those taking the standard deduction—up to $1,000 for singles and $2,000 for joint filers. Itemizers face new floors on charitable deductions and a cap on the tax benefit of itemized deductions at the 35% rate for top earners.
The State and Local Tax (SALT) deduction cap rose significantly (to around $40,000 in recent updates), benefiting residents in high-tax states. Additional perks from the OBBBA, like deductions for tips, overtime pay, auto loan interest, and a $6,000 extra deduction for seniors aged 65+, continue or phase in, though some started earlier.
Overall, these 2026 rules aim to provide tax relief, maintain lower rates, and offer targeted breaks while adjusting for inflation. Taxpayers should review their situation—whether through withholding updates or planning deductions—to maximize benefits.
