Buying or refinancing a home often comes with a long list of closing costs. One of the most misunderstood expenses is mortgage points, also called discount points. Many taxpayers assume they can simply deduct the entire amount in the year they pay it. Sometimes they can—but often they cannot.

The Internal Revenue Code contains specific rules governing the deduction of prepaid interest, and those rules can produce very different tax outcomes depending on whether you are purchasing a home, refinancing an existing mortgage, or acquiring investment property.

Understanding these rules can prevent costly filing mistakes and missed deductions.

What Are Mortgage Points?

Mortgage points are generally prepaid interest paid to a lender in exchange for obtaining a lower interest rate on a loan. Typically, one point equals 1% of the loan amount.

For example:

  • Loan Amount: $400,000
  • Points Paid: 2
  • Amount Paid: $8,000

Although the payment occurs at closing, the tax law does not always permit an immediate deduction.

The General Rule

Congress specifically addressed prepaid interest in IRC § 461(g).

Section 461(g)(1) provides:

“If the taxpayer uses the cash receipts and disbursements method of accounting, prepaid interest shall be charged to capital account and shall be treated as paid in the period to which it is properly allocable.”

In plain English, this means prepaid interest is generally deducted over the life of the loan, rather than entirely in the year it is paid.

Without an exception, taxpayers would normally amortize mortgage points over the loan term.

The Important Exception for Your Principal Residence

Fortunately, Congress created an exception for many homebuyers.

Treasury Regulation § 1.461-1(a)(1) recognizes that certain statutory exceptions allow immediate deductions when specifically authorized.

The IRS has long permitted many taxpayers purchasing their principal residence to deduct qualifying mortgage points in the year paid when all applicable requirements are satisfied, including that:

  • the loan is secured by the taxpayer’s principal residence;
  • paying points is an established business practice in the area;
  • the amount paid is reasonable;
  • the points are computed as a percentage of the loan principal; and
  • the taxpayer actually provides the funds used to pay the points.

When these conditions are met, many homeowners may claim the deduction immediately rather than amortizing it over the loan term.

Refinancing Is Usually Different

Refinancing frequently surprises taxpayers.

Even if points were immediately deductible when purchasing a home, points paid to refinance an existing mortgage generally must be deducted ratably over the life of the new loan.

For example:

  • Original Mortgage: Refinanced into a new 30-year loan
  • Points Paid: $6,000

Instead of deducting $6,000 immediately, the taxpayer may generally deduct approximately $200 per year over the 30-year term, assuming no other special rules apply.

What Happens If You Pay Off the Loan Early?

Suppose you refinance again after only five years.

If you were amortizing points over a 30-year loan, you may generally deduct the remaining unamortized balance when the original loan is completely paid off, assuming the applicable tax rules are satisfied.

This often creates a larger deduction during the payoff year.

Rental Property and Investment Property

The rules become even stricter for rental and investment real estate.

Points paid to acquire or refinance investment property generally are not immediately deductible simply because the property was purchased.

Instead, taxpayers ordinarily recover the prepaid interest through amortization over the applicable loan period.

Common Taxpayer Mistakes

Some of the most common errors include:

  • Deducting refinance points entirely in one year.
  • Forgetting to deduct annual amortization.
  • Ignoring remaining deductible points after paying off a loan.
  • Assuming every item on the closing disclosure is deductible.
  • Confusing loan origination fees with deductible mortgage interest.

Because closing statements often contain numerous charges with similar names, careful review is essential before preparing a return.

Good Recordkeeping Matters

Keep copies of:

  • Closing Disclosure (CD)
  • Settlement Statement
  • Mortgage Note
  • Loan Documents
  • Any refinancing documents

These records help determine:

  • whether the payment actually qualifies as deductible points,
  • whether amortization is required,
  • and how much remains deductible in future years.

Final Thoughts

Mortgage points can produce valuable tax deductions—but only when the statutory requirements are carefully followed. The distinction between purchasing a home and refinancing one frequently changes the timing of the deduction by many years.
