Major tax provisions expiring in the next few years


While the One Big Beautiful Bill Act provided relief by extending TCJA individual provisions through 2028, several important tax benefits are still on expiration schedules that could significantly impact your taxes.


TCJA individual provisions expire after 2028


All the major individual tax benefits extended by the recent legislation will sunset after 2028 unless Congress acts again. According to the Congressional Budget Office, this affects over 150 million taxpayers.


What expires after 2028:

  • Standard deduction reverts from $15,000/$30,000 to approximately $8,500/$17,000 (2029 projected)
  • Tax brackets increase (12% becomes 15%, 22% becomes 25%, etc.)
  • Child tax credit drops from $2,000 to $1,000 per child
  • Section 199A pass-through deduction eliminates entirely
  • Estate tax exemption cuts in half to ~$7.5 million per person

  • SALT deduction cap expires after 2028


    The $10,000 state and local tax deduction limit ends after 2028, allowing full deductibility of state income, property, and sales taxes for itemizers.


    Impact for high-tax state residents: A California couple earning $200,000 with $25,000 in state/local taxes would save approximately $5,550 in federal taxes (22% bracket) once the cap expires.


    Business provisions already expiring


    Several business tax benefits are on faster expiration schedules:


    Bonus depreciation phase-down (2023-2027)


    R&D expense deduction (expired 2022)


    Research and development expenses must now be capitalized and amortized over 5 years (15 years for foreign R&D), rather than fully deducted in the year incurred. This affects software companies, manufacturers, and other innovation-heavy businesses.


    Interest deduction limitations


    The Section 163(j) interest deduction limitation for businesses continues indefinitely, capping deductible business interest at 30% of adjusted taxable income.


    Planning for upcoming expirations


    Individual taxpayers should:

    1. Consider Roth conversions while tax rates remain lower (through 2028)

    2. Accelerate income into lower-rate years if possible

    3. Review estate planning before exemption drops in 2029

    4. Maximize retirement contributions while in potentially lower brackets


    Business owners should:

    1. Accelerate equipment purchases while bonus depreciation remains available

    2. Consider entity structure changes before Section 199A expires

    3. Plan R&D spending around the amortization requirement


    What Congress might do


    Historically, popular individual tax provisions get extended. The American Taxpayer Relief Act of 2012 made many Bush tax cuts permanent, suggesting similar action could occur before 2028.


    Track upcoming changes


    Stay informed about potential legislative changes, as tax law can shift quickly based on political developments and economic conditions.


    Key takeaway: The 2028 sunset of TCJA individual provisions could increase taxes by $1,500-4,000+ annually for middle-class families unless Congress extends them again.

    High-income taxpayers facing the most significant impacts from expiring provisions

    High-income implications of expiring provisions


    High earners face the most dramatic tax increases when current provisions expire, particularly from bracket changes and the return of full SALT deductibility.


    Bracket increases hit hardest at top


    When TCJA individual provisions expire after 2028, the highest earners see the largest dollar impact:


    Example: A single filer earning $400,000 would see their marginal rate increase from 32% to 35% on income between $197,300-$250,525, and from 35% to 39.6% above $250,525. This could increase annual taxes by $3,000-8,000+.


    SALT cap elimination provides major relief


    The $10,000 SALT cap expires after 2028, providing substantial tax cuts for high earners in high-tax states. Per Treasury analysis, 96% of SALT cap benefits flow to taxpayers earning over $100,000.


    High-tax state impact: A New York couple earning $750,000 with $45,000 in state/local taxes would save approximately $13,000 annually (37% bracket) once the cap lifts.


    Estate tax exemption reduction


    The estate tax exemption dropping from ~$14 million to ~$7.5 million per person after 2028 affects ultra-high net worth individuals.


    Section 199A elimination


    High-earning business owners lose the 20% pass-through deduction entirely after 2028, even for non-service businesses.


    Key takeaway: High earners could see net tax changes ranging from significant savings (SALT cap relief) to major increases (bracket changes and lost deductions) depending on their state and income mix.

    Families who could lose significant child-related tax benefits after 2028

    How expiring provisions affect families


    Families face some of the most significant potential tax increases when TCJA provisions expire after 2028, particularly from reduced child tax credits and higher tax brackets.


    Child tax credit reduction


    The child tax credit drops from $2,000 to $1,000 per qualifying child after 2028, with reduced refundability.


    Family impact: A family with three children would lose $3,000 in annual tax benefits, equivalent to a $250 monthly reduction in household cash flow.


    Standard deduction cuts hurt families


    The standard deduction dropping from $30,000 to approximately $17,000 (married filing jointly) means an additional $13,000 of taxable income for families who don't itemize.


    Tax increase example: A family earning $80,000 would owe approximately $1,560 more in federal taxes annually from the reduced standard deduction alone (12% bracket).


    Combined impact for middle-class families


    A typical family with two children earning $75,000 could see their federal tax liability increase by $3,000-4,000 annually from:

  • Reduced child tax credit: $2,000
  • Higher tax brackets: $800-1,200
  • Reduced standard deduction: $1,200-1,800

  • Planning strategies for families


    1. Increase 529 education savings while in lower brackets

    2. Consider dependent care FSA maximization

    3. Build emergency funds to handle potential tax increases

    4. Review life insurance needs if estate exemption drops


    Key takeaway: Middle-class families with children could face $3,000-4,000+ annual tax increases starting in 2029 unless Congress extends current provisions.
