What are the new rules for home mortgage interest deductions? The new federal tax law reduces the limit on home acquisition debt to $750,000. For married taxpayers filing separately, the debt limit is halved to $375,000. In addition the law generally disallows home equity debt interest. Although, home equity interest paid on home equity loans and lines of credit may be deductible if the funds are used to buy, build, or substantially improve the taxpayer’s home that secures the loan. In other words, such loans will be treated as home acquisition debt subject to the new $750,000/$375,000 limits
Under the old rules, taxpayers could deduct interest paid on up to $1 million ($500,000 if married filing separately) of home acquisition debt (debt used to buy or substantially improve a first or second home). Also, taxpayers could deduct interest paid on up to $100,000 ($50,000 if married filing separately) of home equity debt, regardless of how the proceeds were used. The TCJA cuts those numbers back significantly.
Thanks to a set of grandfather rules, the new limits don’t apply to home acquisition debt that was taken out on or before 12/15/17 (or taken out on or before that date and refinanced later). This is good news for existing homeowners. However, if you have a home equity loan or line of credit, we will need to trace how the proceeds were used to determine if the interest is still deductible under the new law.
