HELOC Tax Deduction Rules

The IRS changed the rules in 2017. Here's exactly what you need to know about deducting HELOC interest.

Deductible — When Used For:

  • Home improvements that substantially improve your home (kitchen remodel, addition, new roof, HVAC replacement)
  • Buying or building the home that secures the HELOC
  • "Substantial" means the improvement adds value, prolongs life, or adapts the home to new uses

Not Deductible — When Used For:

  • Debt consolidation (paying off credit cards)
  • Education expenses or student loans
  • Business funding or investments
  • Personal expenses, vacations, vehicles

The $750K Rule Explained

Under the Tax Cuts and Jobs Act (TCJA, 2017), HELOC interest is only deductible when the loan is used to "buy, build, or substantially improve" the home securing the loan. The combined mortgage debt limit is $750,000 (MFJ) or $375,000 (MFS).

2017 Tax Law Changed Rules

Track your usage. The IRS requires you to trace how HELOC funds were used. If you borrow for multiple purposes, the deductible portion depends on how much went to home improvements. Keep receipts and records.
