Whether closing costs are added to basis or deductible depends on what each fee paid for: charges tied to transferring ownership of the property get added to your cost basis, a handful of charges (property taxes, qualifying mortgage points, and reinstated PMI premiums) are deductible the year you buy if you itemize, and loan-processing fees and personal expenses like homeowner’s insurance give you no tax benefit at all.1Internal Revenue Service. Publication 551 (12/2025), Basis of Assets Sorting your Closing Disclosure into those three buckets is worth real money, because every dollar you capitalize into basis shrinks the taxable gain when you eventually sell.
The Cash Test
The IRS uses one practical question to decide where a settlement charge belongs: would you still have paid this fee if you had bought the property with cash?2Internal Revenue Service. Publication 551 (12/2025), Basis of Assets – Section: Settlement Costs If yes, it attaches to the property and gets added to basis. If the fee only exists because you took out a mortgage, it attaches to the loan and does not.
Title insurance, recording fees, and transfer taxes pass the cash test because they relate to the ownership transfer itself. A lender-ordered appraisal, a credit report pull, and loan origination charges fail it because they exist to serve the mortgage. From there, loan-related and personal charges split again: some are deductible in the purchase year, and some simply aren’t deductible at all.
Closing Costs That Add to Your Basis
Costs that pass the cash test are capitalized, meaning they are added to the purchase price to establish your initial basis in the property. Publication 551 lists these settlement costs as capitalizable:2Internal Revenue Service. Publication 551 (12/2025), Basis of Assets – Section: Settlement Costs
- Abstract and title search fees
- Owner’s title insurance (the lender’s policy is a loan cost and does not count)
- Recording fees paid to the county
- Transfer or stamp taxes imposed by the state or locality
- Surveys
- Legal fees for the sales contract, title review, and deed preparation
- Impact fees and utility connection charges
- Any seller obligations you agreed to pay, such as back taxes, accrued interest, or repairs the seller owed
That last category trips people up. If you covered the seller’s delinquent property taxes or picked up a repair bill the seller was responsible for, that money is folded into your basis rather than deducted separately. It is treated as part of what you paid to acquire the property.
Seller Credits
Seller credits reduce your basis rather than add to it. Seller-paid points on your mortgage require you to reduce your basis by the amount of those points.1Internal Revenue Service. Publication 551 (12/2025), Basis of Assets A general seller credit that lowers the effective purchase price works the same way. On a $300,000 sale with an $8,000 seller credit, your starting basis is $292,000, plus any capitalizable closing costs you paid out of pocket.
Closing Costs You Can Deduct the Year You Buy
A smaller group of settlement charges gives you a tax benefit now instead of later. Because you get the benefit in the purchase year, these items cannot also be added to basis. Claiming both would double-count the deduction.
All of these deductions require you to itemize on Schedule A. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If your itemized total does not clear that threshold, these line items will not save you anything on their own.
Prorated Property Taxes
Real estate taxes prorated to you from the closing date forward are deductible as part of the state and local tax (SALT) deduction. For 2026, the SALT cap is $40,000 for most filers ($20,000 for married filing separately), with a phase-down for taxpayers whose modified adjusted gross income exceeds $500,000.4Internal Revenue Service. Topic No. 503, Deductible Taxes That single cap has to accommodate property taxes, state income taxes, and local taxes together.
Mortgage Points and Prepaid Interest
Points paid to get a mortgage on your principal residence can usually be deducted in full the year you buy, as long as the loan is secured by your main home, paying points is a standard practice in your area, and the amount is clearly itemized on your settlement statement.5Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction – Section: Points Prepaid mortgage interest that covers the gap between your closing date and your first scheduled payment is also deductible in the purchase year.
Points that don’t meet all the requirements, including points paid on a refinance or on a loan secured by a second home, must be spread evenly over the life of the loan instead.6Internal Revenue Service. Topic No. 504, Home Mortgage Points Points are treated as interest either way, which is why they never add to basis.
Mortgage Insurance Premiums
The itemized deduction for private mortgage insurance premiums has moved on and off the books. Congress reinstated it starting with the 2026 tax year. If you pay PMI on a qualified mortgage, those premiums are deductible on Schedule A again, subject to income phase-outs. PMI is a loan cost, so it is never added to basis regardless of whether the deduction is available in a given year.
Closing Costs That Give You Nothing
A handful of common settlement charges sit in a frustrating middle ground. They cannot be capitalized because they fail the cash test, and they cannot be deducted because the Code does not allow it. You pay them, and the tax code treats them as a cost of doing business.
- Homeowner’s insurance premiums, which are a personal expense of using the property
- Escrow deposits set aside for future tax and insurance payments, which have not been spent yet
- Lender-required appraisal fees
- Credit report fees
- Loan origination fees charged by the lender for processing the mortgage
Publication 936 states directly that lender-required charges for services such as appraisals, notary fees, and mortgage note preparation are not deductible as interest and cannot be treated as points.7Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction – Section: Amounts Charged for Services They are absorbed as part of the cost of borrowing.
If you are buying a rental or other investment property, the same closing-cost classifications apply, but capitalized costs are recovered through annual depreciation rather than waiting until sale.8Internal Revenue Service. Publication 527 (2025), Residential Rental Property
Why the Classification Matters at Sale
Capitalized closing costs reduce the gain you report when you sell. The sale-year math is straightforward: amount realized, minus selling expenses, minus your adjusted basis, equals your capital gain or loss. Adjusted basis is your purchase price, plus capitalized closing costs, plus any later capital improvements, minus any depreciation claimed.
If the property was your primary residence and you owned and lived in it for at least two of the five years before the sale, you can exclude up to $250,000 of gain ($500,000 for married couples filing jointly) under Section 121.9Office of the Law Revision Counsel. 26 U.S. Code 121 – Exclusion of Gain From Sale of Principal Residence For the joint exclusion, both spouses must meet the use requirement and at least one must meet the ownership requirement.10eCFR. 26 CFR 1.121-1 – Exclusion of Gain From Sale or Exchange of a Principal Residence
For many owners, that exclusion wipes out the gain and the basis arithmetic feels academic. For long-time owners in high-appreciation markets, or for anyone who converted a rental into a residence, the gain can run well past the exclusion. That is when every capitalized title fee and transfer tax from closing day earns its keep.
Working the other direction has consequences. Overstating basis to shrink a reported gain triggers a 20% accuracy-related penalty on the resulting underpayment, and if the claimed basis is 200% or more of the correct figure, the penalty doubles to 40%.11Office of the Law Revision Counsel. 26 U.S. Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Those penalties stack on top of the tax owed and interest.
Records to Keep
The IRS expects documentation supporting your adjusted basis for at least three years after you file the return for the year you sell.12Internal Revenue Service. Publication 523 (2025), Selling Your Home Practically, that means holding the records for as long as you own the property plus three years, because the sale-year calculation reaches all the way back to the purchase.
Your Closing Disclosure is the single most important document. It itemizes every fee you paid at settlement, which is what lets you separate the capitalized items from the deductible ones from the ones that gave you nothing. Save it along with receipts for later capital improvements, contractor invoices, and renovation permits. These records may need to survive for decades, so digital copies in more than one location are the realistic approach.
