法律改变了什么

按揭利息扣除

  • Reduces the limit on deductible mortgage debt to $750,000 for new loans taken out after Dec. 14, 2017.
  • Current loans of up to $1 million are grandfathered and not subject to the new cap. Neither limit is indexed for inflation.

房屋净值贷款利息扣除

  • Repeals the deduction for interest paid on home equity debt through Dec. 31, 2025.
  • Interest remains deductible on home equity loans (or second mortgages) if the proceeds are used to substantially improve the residence.

州和地方财产税减免

  • Caps the itemized deduction for state and local property taxes (and income or sales taxes) at $10,000. This limit isn’t indexed for inflation.
  • This deduction was previously unlimited.

移动费用

  • Repeals the moving expense deduction except for members of the Armed Forces.

标准扣除

  • Doubles the standard deductions for individual filers to $12,000 and joint filers to $24,000. This deduction is indexed for inflation.
  • This greatly reduces the value of the itemized MID and property tax deductions as tax incentives for homeownership, as more filers are expected to take the standard deduction rather than itemizing.

什么不会改变

不动产同类交易

  • Retains the Section 1031 Like Kind Exchange rule for real property, but repeals the use of Section 1031 for personal property.
