No: a $600,000 sale price is not automatically $600,000 of taxable profit, and missing kitchen receipts do not by themselves establish that every improvement is disallowed. Federal tax generally depends on the home’s sale proceeds after relevant selling expenses, its adjusted basis, and whether you qualify for the main-home gain exclusion. A 72-year-old’s age and sale price alone are not enough to calculate the tax.
Do you pay tax on the full $600,000 sale price?
Usually, home-sale tax is figured on gain, not simply on the gross price. The calculation begins with the amount realized from the sale, generally accounting for relevant selling expenses, and compares it with the home’s adjusted basis. The IRS provides worksheets and instructions in Publication 523 (2025).
Adjusted basis generally starts with what you paid to acquire the home. It may increase for qualifying capital improvements and decrease for specified items, such as depreciation and certain credits, reimbursements, or losses. The IRS summarizes the general rule this way: “Your adjusted basis is generally your cost in acquiring your home plus the cost of any capital improvements you made, less casualty loss amounts and other decreases.” See the IRS property-basis FAQ.
That means a $600,000 sale price, without the purchase price, selling costs, basis adjustments, and exclusion details, cannot show how much gain there is or how much of it might be taxable.

Can the kitchen remodel increase the home’s tax basis?
Possibly. The tax treatment depends on the work, not simply the label “kitchen remodel.” A capital improvement may increase basis; ordinary repairs or maintenance generally do not. A project’s components may need to be assessed according to what was actually done and the applicable IRS rules. Do not assume every kitchen-related expense adds to basis.
Missing original receipts do not establish that the entire remodeling cost is automatically disallowed, but neither does a recollection of decades of work establish an allowable amount. The IRS says, “Any time you buy real estate, you should keep records to document the property’s adjusted basis.” That is guidance to retain support for basis; it does not say that an original receipt is the only form of evidence in every case. Discuss the available documentation and specific costs with a qualified tax professional.

What records should you gather if receipts are missing?
Collect what remains that may help identify the work, cost, timing, and who paid. These materials are useful to review with a tax professional, not a guarantee that any particular expense qualifies.
- Home purchase records and the closing statement.
- Contractor invoices, permits, canceled checks, bank statements, and credit-card statements.
- Insurance or subsidy records that may relate to project costs.
- Prior tax records, including records of rental or business use and depreciation.
- Records of selling expenses, along with a timeline of what work was done and when.
Publication 523 (2025) gives general guidance to keep records documenting adjusted basis until three years after the due date of the return for the year of sale. For older work, gather available records rather than assuming one missing document settles the tax treatment.

How much gain might the main-home exclusion cover?
A qualifying seller may be able to exclude up to $250,000 of gain, or up to $500,000 for certain married people filing jointly. These limits apply to gain, not the home’s gross sale price. The IRS’s general rule is that a seller must normally have owned and used the home as a main home for at least two years during the five-year period ending on the sale date; exceptions and special rules can apply. See IRS Topic no. 701 and Publication 523 (2025).
If gain exceeds the exclusion available, or the seller does not qualify, some gain may be taxable and reportable. Rental or business use and depreciation can change the analysis. The title does not provide the facts needed to determine eligibility or calculate any remaining taxable gain.
Rank #4
What information is needed to estimate the tax?
A meaningful estimate would require, at minimum, the purchase price and relevant acquisition records, sale proceeds and selling expenses, support for possible capital improvements and other basis adjustments, filing status, ownership and use history, and details of any previous home-sale exclusions. Rental or business use and depreciation also matter. State tax cannot be determined from the facts given; the rules discussed here are federal.
