In the labyrinth of tax documents that follow a mortgage refinance, Form 1098 serves as a key. While Box 1 reports the straightforward interest you paid, Box 6 introduces a more complex concept: points. For a homeowner who has refinanced, the number in Box 6 is not a simple figure to be deducted. It represents prepaid interest that must be navigated with specific, often misunderstood, IRS rules. Misapplying these rules is a common error that can lead to filing inaccuracies.
This article provides a comprehensive examination of Box 6 in the context of a refinance. We will define what points are, contrast their treatment in a purchase versus a refinance, and provide the precise methodology for deducting them over time. We will explore the necessary calculations, the implications of selling or refinancing again, and the critical documentation required to support your tax position.

The Nature of Points: Prepaid Interest for a Lower Rate
Points, also called loan origination points or discount points, are fees you pay a lender at closing in exchange for a reduced interest rate on your mortgage. One point typically costs 1% of the loan amount. From a tax perspective, points are considered a form of prepaid interest.
This characterization is why they are reportable on Form 1098 and why they are potentially deductible. However, the IRS draws a sharp distinction between points paid to purchase a home and points paid to refinance one. This distinction is the root of most confusion surrounding Box 6.
Table 1: Key Definitions for Box 6
| Term | Definition | Tax Implication |
|---|---|---|
| Points (Discount Points) | An upfront fee paid to a lender to reduce the interest rate on a mortgage. 1 point = 1% of the loan amount. | Treated as prepaid interest. Deductibility depends on loan purpose. |
| Box 6 (Form 1098) | The amount of points paid by the borrower that the lender is reporting to the IRS. | This is the starting figure for your deduction calculation, not the final amount. |
| Origination Fee | A separate fee charged by the lender for processing the loan application. | Not deductible as interest. It is a cost that adds to your basis in the home. |
The Fundamental Divide: Purchase vs. Refinance
The purpose of the loan dictates the deductibility of points. This is the most critical concept to grasp.
- Points on a Purchase Loan: When you pay points to acquire your main home, they are generally fully deductible in the year you pay them. The IRS views this as interest paid to secure the mortgage used to buy the property.
- Points on a Refinance Loan: When you pay points to refinance an existing mortgage, the IRS mandates that you must deduct them ratably over the life of the new loan. The logic is that you are paying interest to secure a new loan that will benefit you over many years; therefore, the expense should be recognized over that same period.
This means the amount reported in Box 6 of your new lender’s Form 1098 is not fully deductible in the year of the refinance. You must calculate a yearly deduction amount.
The Calculation: Spreading Points Over the Loan Term
The process for deducting refinance points is a straightforward application of amortization. You will deduct a proportionate share of the points each year until the loan is paid off or terminated.
The formula for calculating your annual deduction is:
\text{Annual Points Deduction} = \frac{\text{Total Points Paid (Box 6)}}{\text{Loan Term in Years}}For greater precision, especially in the first and last years of the loan, it is better to calculate it on a monthly basis.
\text{Monthly Points Deduction} = \frac{\text{Total Points Paid (Box 6)}}{\text{Loan Term in Months}}You then multiply this monthly amount by the number of months in the tax year that you held the mortgage.
Illustrative Calculation:
Assume you refinanced your home on September 1, 2023, taking out a new 30-year mortgage (360 months). At closing, you paid \text{\$4,500} in points to secure a lower rate. This amount appears in Box 6 of the Form 1098 you receive from your new lender in January 2024.
- Step 1: Find the monthly deduction.
Step 2: Determine the number of months the loan was held in the tax year.
You closed on September 1, 2023. The loan was in place for September, October, November, and December of 2023. That is 4 months.
Step 3: Calculate your deductible points for the 2023 tax year.
\text{2023 Deduction} = \text{\$12.50} \times 4 = \text{\$50.00}For the 2024 tax year, and every full year thereafter, you would deduct \text{\$12.50} \times 12 = \text{\$150.00}. You will continue this pattern for the life of the 30-year loan.
The Accelerated Deduction: What Happens When You Sell or Refinance Again
The “ratably over the life of the loan” rule has a crucial exception. If you pay off the loan before its term ends—either by selling the home, refinancing again, or simply paying it off early—you get to deduct all of the remaining unamortized points in that final tax year.
This rule prevents you from losing the deduction for the points you paid.
Continuing from the previous example:
- You have been deducting \text{\$150} per year for 5 full years (2024-2028). Total deducted so far: \text{\$150} \times 5 = \text{\$750}. You also deducted \text{\$50} in 2023, for a total of \text{\$800}.
- In January 2029, you decide to sell the house and pay off the mortgage.
- The remaining unamortized points are: \text{\$4,500} - \text{\$800} = \text{\$3,700}.
- In the tax year of the sale (2029), you can deduct the entire remaining \text{\$3,700} in points, in addition to the regular \text{\$150} deduction for the portion of the year you held the loan (January).
This accelerated deduction can provide a significant tax benefit in the year you sell your property.
Documentation and Compliance: Proving Your Deduction
The IRS may question the deduction of points, especially the large deduction taken in the year of a sale. Therefore, maintaining impeccable records is non-negotiable.
Your loan closing documents, specifically the Closing Disclosure (CD), are your primary evidence. The CD will itemize the points paid in the “Loan Costs” section. You must keep this document for as long as you own the loan plus three years after you file the return for the year you finally deduct the last of the points.
Table 2: Documenting Your Box 6 Deduction
| Document | Purpose | Why It’s Critical |
|---|---|---|
| Form 1098, Box 6 | Provides the official total of points paid that the lender reported to the IRS. | Your starting figure for the deduction calculation. |
| Closing Disclosure (CD) | Itemizes all closing costs, providing a detailed breakdown showing the points paid. | Proof of payment. Essential to have if the IRS ever questions the deduction. |
| Loan Note | Specifies the term of the loan (e.g., 30 years, 360 months). | Necessary for determining the amortization period for the ratable deduction. |
Special Considerations and Pitfalls
- Points on a Cash-Out Refinance: If you do a cash-out refinance, where the new loan is larger than the old mortgage balance, the points must be allocated. Only the points associated with the amount of the new loan that went to refinance the old principal balance are deductible under these rules. The points allocable to the “cash-out” portion of the loan are not deductible as interest. You must calculate the percentage of the loan used for refinancing and apply that to the total points paid.
- Example: Your old loan had a payoff of \text{\$280,000}. You refinance with a new loan of \text{\$350,000}, taking \text{\$70,000} in cash. You pay \text{\$3,500} in points.
- The percentage of the loan for refinancing is: \frac{\text{\$280,000}}{\text{\$350,000}} = 80\%
- The deductible points are: \text{\$3,500} \times 0.80 = \text{\$2,800}
- You would amortize only \text{\$2,800} over the life of the loan, not the full \text{\$3,500}.
- Not All Fees in Box 6 are Points: Lenders may sometimes report other fees in Box 6. Cross-reference the Box 6 amount with the “Points” line on your Closing Disclosure to ensure they match. Do not assume other origination fees are deductible.
Conclusion: A Long-Term Tax Asset
For those who have refinanced, Box 6 of Form 1098 does not represent a immediate tax benefit. Instead, it represents a long-term tax asset to be drawn down over the life of your loan. It requires a shift in perspective—from seeking a single-year deduction to managing a multi-decade schedule of small, predictable deductions.
Understanding the ratable deduction rule is essential for accurate tax filing. By performing the correct monthly calculation, maintaining thorough records of your closing documents, and knowing the rules for accelerating the deduction upon sale, you transform Box 6 from a source of confusion into a clear, strategic element of your long-term financial planning. This knowledge ensures you claim every dollar of deduction you are entitled to, precisely when you are entitled to claim it.
