Are Mortgage Points Tax Deductible? Complete IRS Section 461(g) Rules
When closing on a home mortgage, points paid to reduce your interest rate can amount to thousands of dollars. A critical question for tax planning is whether you can deduct these points on your federal income tax return.
Under the Internal Revenue Code (IRC) §461(g) and IRS Publication 936 (Home Mortgage Interest Deduction), mortgage discount points are treated as prepaid interest. However, whether you can deduct them all at once or must spread them over 30 years depends entirely on how the loan is structured.

1. General Rule: Ratable Deduction vs. Upfront Exception
As a general tax principle under IRC §461(g)(1), prepaid interest cannot be deducted in the year paid. Instead, it must be capitalized and deducted ratably over the period to which it applies.
However, IRC §461(g)(2) provides a massive statutory exception:
> Discount points paid on indebtedness incurred in connection with the purchase or improvement of a principal residence are fully deductible in the taxable year paid, provided the transaction meets standard geographic business practices.

2. Primary Residence Purchase: The IRS 9-Point Test
To deduct 100% of mortgage discount points in the calendar year you buy your primary home, your closing must satisfy all nine criteria outlined in IRS Publication 936:
- Secured by Principal Residence: The loan must be secured by your main home (the home where you spend the majority of your time).
- Established Business Practice: Paying discount points must be an established business custom in the area where the loan was made.
- Reasonable Amount: The points paid must not exceed the amount generally charged in that regional market.
- Cash Accounting Method: You must report your taxes using the cash method (which almost all individual taxpayers do).
- Not in Place of Other Fees: The points must be strictly for prepaid interest, not disguised fees for document preparation, appraisal, title, or inspections.
- Computed as a Percentage: The points must be calculated as a direct percentage of the loan principal (e.g. 1 point = 1%).
- Clearly Broken Out: The points must be clearly identified on your Closing Disclosure (CD) or HUD-1 Settlement Statement.
- Direct Funds Provided: The funds you paid at or before closing (down payment, earnest money, and cash to close) must equal at least the total points charged.
- Loan Used for Home Purchase/Build: The borrowed funds were used to buy or construct your primary residence.
Note on Seller-Paid Points: If the home seller pays discount points on your behalf as a closing concession, the IRS still treats those points as if you paid them! You can deduct the seller-paid points on your return, but you must reduce your home's cost basis by the amount of points paid by the seller.

3. Refinances and Second Homes: Ratable Amortization
If you pay points on a refinance or a second vacation home, the upfront deduction under §461(g)(2) does not apply.
Instead, you must deduct the points ratably over the life of the loan:
Monthly Tax Deduction = Total Points Cost ÷ Total Loan Term (in Months)
Example:
You refinance into a $360,000, 30-year (360-month) mortgage and pay 1 point ($3,600):
- Annual Deduction: $3,600 ÷ 30 Years = $120.00 per year ($10.00 / month).
- In Year 1, if you closed in July (6 months of payments), your deduction is 6 × $10 = $60.00.
The Exception for Home Improvements:
If a portion of the refinanced loan proceeds was used for substantial home improvements on your primary residence, you can immediately deduct the points allocable to the home improvement portion in the year paid.

4. What Happens to Unamortized Points When You Refinance Again?
This is one of the most overlooked tax deductions in real estate:
If you are ratably deducting points on a refinanced mortgage and you refinance again or pay off the loan early (e.g. through selling the house), you can deduct all remaining unamortized points in the year of payoff!
Example:
You paid $3,600 in points on a 30-year refinance. After 5 years (60 months), you have deducted $600. If you refinance or sell the home in Year 5, you can immediately write off the remaining $3,000 of unamortized points on that year's Schedule A!
Warning: If you refinance with the exact same lender, IRS rules require you to continue amortizing the remaining points over the term of the new loan rather than deducting them all at once.

5. The Standard Deduction Reality Check
Even if points are deductible, you will only see tax relief if you itemize deductions on Schedule A (Form 1040).
For 2026, the statutory federal standard deductions are:
- Single: $16,100
- Married Filing Jointly: $32,200
- Head of Household: $24,150
If your total itemized deductions (mortgage interest, points, state and local taxes capped at $10k SALT, and charitable contributions) do not exceed your standard deduction, you will claim the standard deduction, and the tax benefit of your mortgage points will be $0.
