About this EA exam topic

State-and-local tax (SALT) and mortgage-interest deductions are itemized-deduction topics the EA exam tests for limits and qualification. You will apply the SALT deduction cap and decide which taxes count toward it.

Mortgage-interest questions test acquisition debt versus home-equity debt, the debt-limit ceiling on deductible interest, and points. Expect fact patterns that mix a refinance, a second home, or equity debt used for non-home purposes.

What you'll be tested on

  • The SALT deduction cap and which taxes are included
  • Acquisition debt vs. home-equity debt and the deductible-interest limit
  • Treatment of points paid on a purchase vs. a refinance
  • When itemizing beats the standard deduction

How to prepare

  • Know exactly which taxes count toward the SALT cap.
  • Separate acquisition debt from equity debt. The deductibility hinges on how proceeds were used.
  • Compare total itemized deductions against the standard deduction in every scenario.
