Recent tax reform legislation affected many provisions in the tax code. Many were modified, either permanently or temporarily, while some were repealed entirely. Here are five that survived.
1. Mortgage Interest Deduction
While the House bill repealed the mortgage interest deduction, the final version of the act retained it, albeit with modifications. First is that the allowed interest deduction is limited to mortgage principal of $750,000 on new homes (i.e., new ownership). For prior tax years, the limit on acquisition indebtedness was $1 million. Existing mortgages are grandfathered in, however, and taxpayers who enter into binding contracts before December 15, 2017, to close on the purchase of a principal residence before January 1, 2018, and who purchase such residence before April 1, 2018, are able to use the prior limit of $1 million.
2. Personal Taxes: State and Local Income Tax, Sales Tax and Property Tax
In prior years, taxpayers who itemize were allowed to deduct the amount they pay in state and local taxes (SALT) from their federal tax returns. Slated for repeal (with the sole exception of exception of a state and local property tax deduction capped at $10,000) under both the House and Senate versions of the tax bill, SALT remained in the final tax reform bill in modified form. As such, for taxable years 2018 through 2025, the aggregate deduction for property taxes, state, local, and foreign income taxes, or sales taxes is limited to $10,000 a year ($5,000 married filing separately).
