Loan-related closing costs on an investment or business property are written off over the full term of the mortgage, so a 30-year loan sets a 30-year amortization life for closing costs tied to financing, and a 15-year loan cuts that in half. That schedule applies to a specific set of fees: loan origination charges, lender-required appraisals, credit report fees, and loan assumption fees. Other closing costs follow different rules entirely. Some get added to the property’s basis and recovered through depreciation or at sale, a few are deductible the year you pay them, and points have their own treatment that depends on how you use the property.1Internal Revenue Service. Publication 527 – Residential Rental Property
Which Closing Costs Actually Get Amortized
The amortization bucket is narrower than many buyers assume. It covers the costs of obtaining the loan, not the costs of acquiring the property. The IRS draws a sharp line between the two: fees for getting the loan go on an amortization schedule tied to the loan term, while fees for getting the property go into basis.
Fees that belong on the amortization schedule include:
- Loan origination fees
- Lender-required appraisal charges
- Credit report fees
- Loan assumption fees
One threshold matters more than any other for whether you get this treatment at all: the property has to be an investment or business asset. A primary residence that you don’t rent or use for business doesn’t produce an annual amortization deduction for these loan costs. Investment and rental property owners get the amortization because the fees are ordinary costs of carrying a business asset.
How to Calculate the Annual Deduction
The math is straightforward. Add up the eligible loan costs, divide by the number of months in the loan term, and deduct that monthly amount for each month the loan is outstanding during the tax year.
On a 30-year mortgage, $3,600 in loan origination fees works out to $10 a month, or $120 for a full year. The same $3,600 on a 15-year note runs $20 a month, or $240 a year. In the first and last years of the loan, prorate for the number of months the loan was actually in place.
Closing Costs That Go Into Basis Instead
Costs tied to transferring ownership of the property are not amortized. They get folded into your cost basis. For rental or business property, that higher basis flows into your annual depreciation deduction. For a personal residence, it reduces your taxable gain when you sell.
The IRS treats these settlement costs as basis-increasing:
- Title insurance premiums
- Attorney and legal fees
- Recording fees
- Survey costs
- Transfer taxes
- Abstract fees
- Charges for installing utility services
- Seller obligations you agree to pay, such as back taxes, sales commissions, or repair charges
None of these can be amortized separately. They become part of the property for tax purposes.2Internal Revenue Service. Rental Expenses
Closing Costs You Can Deduct the Year You Pay Them
A short list of items gives you a current-year deduction. Prorated real estate taxes picked up by the buyer at closing are deductible: on Schedule A for a personal residence, or on the appropriate business schedule for an investment property. Prepaid interest covering the stub period between your closing date and your first full mortgage payment is also deductible the year it’s paid, but only for the portion that actually falls in that tax year. If a loan closes on November 15, the prepaid interest covers November 15 through November 30, and that is what you deduct. You cannot accelerate interest that belongs to the following year.3Internal Revenue Service. Topic No. 505 – Interest Expense
Points: The Rule Flips by Property Type
Points are the closing cost where tax treatment swings most dramatically based on how the property is used. The term covers loan origination fees, discount points, and similar percentage-based charges. Because points are prepaid interest, the IRS applies different rules for a home purchase, an investment property, and a refinance.
Points on a Primary Residence Purchase
Points paid on a loan to buy or substantially improve your principal residence can be deducted in full the year you pay them if you meet several conditions. The loan has to be secured by the home, paying points has to be an established business practice in your area, and the amount charged has to be in line with local norms. You must provide funds at or before closing at least equal to the points charged, and the points have to be shown clearly as points on the settlement statement.4Internal Revenue Service. Topic No. 504 – Home Mortgage Points This immediate deduction is a statutory exception. IRC ยง461(g) generally requires prepaid interest to be spread over the period it covers, but it carves out points paid on a loan to purchase or improve a principal residence.5Office of the Law Revision Counsel. 26 U.S. Code 461 – General Rule for Taxable Year of Deduction
Points on an Investment or Business Property
Points paid to finance a rental or business property have to be deducted over the term of the loan, even if they would qualify for immediate deduction on a personal residence. The IRS treats them as original issue discount and spreads the deduction across the life of the mortgage.1Internal Revenue Service. Publication 527 – Residential Rental Property
Points on a Refinance
Refinancing points generally can’t be deducted in the year paid, even on your primary residence. You spread them over the life of the new loan. One exception: if part of the refinance proceeds is used to substantially improve the home and you meet the standard tests, the share of points allocable to the improvement is immediately deductible, and the rest is amortized over the loan term.6Internal Revenue Service. Publication 936 – Home Mortgage Interest Deduction
Seller-Paid Points
When a seller pays points on behalf of a buyer on the buyer’s primary residence, the IRS treats it as though the buyer received cash and used it to pay the points. The buyer can deduct the seller-paid points if the standard tests are met, but must reduce the home’s basis by that amount, which raises the taxable gain at a future sale. The seller treats the payment as a selling expense.6Internal Revenue Service. Publication 936 – Home Mortgage Interest Deduction
What Happens if You Refinance or Pay the Loan Off Early
The amortization schedule is tied to the existence of the debt. If the loan disappears through sale, payoff, or refinance with a different lender, the remaining unamortized balance of loan costs becomes fully deductible in the year the debt is extinguished. A 30-year loan paid off after 10 years lets you claim the remaining 20 years of unamortized costs as a single lump-sum deduction that year.
Refinancing with the same lender works differently. The IRS may require you to add the remaining unamortized balance from the old loan to the costs of the new loan and amortize the combined amount over the new loan’s term. That restarts the clock rather than freeing up the lump-sum deduction, so refinancing with the same lender is less tax-favorable for this expense than switching to a different one.
A Separate 180-Month Track for Entity Formation Costs
If acquiring the property involves forming a new business entity, there’s a second amortization period to know about. Legal fees for drafting operating agreements and similar costs to set up an LLC or partnership are organizational expenses, not property acquisition costs. These run on a 180-month (15-year) amortization schedule rather than tracking the loan term.
Partnership organizational expenses include an immediate deduction of up to $5,000 in the year the business begins, with the balance spread over 180 months. The $5,000 phases out dollar-for-dollar once total organizational expenses exceed $50,000.7Office of the Law Revision Counsel. 26 U.S. Code 709 – Treatment of Organization and Syndication Fees Start-up expenditures for a new trade or business follow the same structure: up to $5,000 immediate deduction, same $50,000 phase-out, balance amortized over 180 months starting in the month the business begins operating.8Office of the Law Revision Counsel. 26 U.S. Code 195 – Start-Up Expenditures
These rules apply to the business formation only. Closing costs on the property itself still follow the basis or loan-life amortization rules above. Keep the two categories separate in your records.
Reporting the Deduction and Keeping the Records
Where the deduction lands depends on how you hold the property. Rental owners report on Schedule E, a sole proprietor using the property for business operations uses Schedule C, and farm property goes on Schedule F.9Internal Revenue Service. About Schedule E (Form 1040)
The first year of amortization is reported on Form 4562, Part VI, which covers amortization of capital costs. You enter the total amortizable amount, the date amortization begins, the amortization period, and the current-year deduction. In later years, if Form 4562 isn’t otherwise required, you can report the ongoing annual amortization directly on the “Other Expenses” line of the applicable schedule.10Internal Revenue Service. Instructions for Form 4562
Your Closing Disclosure (or the older HUD-1 Settlement Statement for pre-2015 transactions) is the foundation document for the calculation. It itemizes every closing cost and shows which party paid it.11Consumer Financial Protection Bureau. Appendix A to Part 1024 – Instructions for Completing HUD-1 and HUD-1a Settlement Statements Keep it with the loan agreement and a self-prepared amortization schedule that tracks each year’s deduction and the remaining unamortized balance.
Hold these documents longer than you probably think. The IRS wants property-related records kept until the statute of limitations expires for the year you dispose of the property. In practice, that means at least three years after filing the return for the year of sale, and six years if there’s any chance of underreporting income by more than 25%.12Internal Revenue Service. How Long Should I Keep Records? For a rental held 20 years, that can mean keeping the original Closing Disclosure for over two decades.
