How to Calculate Gain or Loss on Sale of Property in 2025

When selling property in the United States 🇺🇸, understanding how to calculate the gain or loss, what tax rules apply, and what documentation is required is essential. Whether you are a homeowner, a recent immigrant, or someone with a more complex situation involving business or rental use, knowing the requirements can help you avoid costly mistakes. This guide provides a thorough overview of who qualifies for the main home exclusion, detailed eligibility criteria with real-world examples, required documentation with official links, a step-by-step application process, and practical tips for meeting all requirements.

Who Qualifies for the Main Home Exclusion?

The main home exclusion is a special tax rule that allows many homeowners to exclude up to $250,000 of gain ($500,000 for married couples filing jointly) from their income when they sell their main home. To qualify, you must meet both the ownership and use tests:

• Ownership Test: You must have owned the home for at least two years during the five-year period ending on the date of sale.
• Use Test: You must have lived in the home as your main home for at least two years during the same five-year period.

Both tests do not need to be met at the same time, but both must be satisfied within the five-year window before the sale. If you are married and filing jointly, at least one spouse must meet the ownership test, and both must meet the use test.

Example 1:
Maria bought a house in 2020 and lived there until 2024. She sells the house in 2025. She meets both the ownership and use tests, so she may qualify for the exclusion.

Example 2:
John bought a house in 2019 but rented it out until 2023. He moved in and lived there from 2023 to 2025. He only meets the use test for two years but not the ownership test for two years as his main home, so he may not qualify for the full exclusion.

Detailed Eligibility Criteria

To claim the main home exclusion, you must meet these requirements:

1. Ownership and Use:
– You must have owned and lived in the home as your main home for at least two out of the last five years before the sale.
– The two years do not have to be continuous or immediately before the sale.

2. Frequency of Exclusion:
– You cannot claim the exclusion if you have already claimed it for another home sold within the last two years.

3. Special Circumstances:
– If you had to sell your home because of work, health, or an unforeseen event, you may qualify for a reduced exclusion even if you did not meet the two-year rule. The reduced exclusion is based on the portion of the two years you did meet.

4. Business or Rental Use:
– If you used part of your home for business or rented it out, you may have to pay tax on the gain related to that part. The exclusion only applies to the part used as your main home.

5. Non-Qualifying Sales:
– If you acquired the home through a like-kind exchange (also called a 1031 exchange) within the last five years, you cannot claim the exclusion.
– If you are subject to expatriate tax rules, you may not qualify.

6. Reporting Requirements:
– Even if your entire gain is excluded, you may still need to report the sale on your tax return using Schedule D (Form 1040).

Required Documentation

To support your claim for the main home exclusion and to calculate your gain or loss, you should keep the following documents:

• Purchase Documents: Closing statement, purchase contract, and proof of payment.
• Improvement Records: Receipts and contracts for home improvements (not repairs).
• Depreciation Records: If you claimed depreciation for business or rental use.
• Selling Documents: Closing statement from the sale, proof of selling expenses (commissions, legal fees, advertising, loan charges).
• Proof of Residency: Utility bills, driver’s license, voter registration, or tax returns showing your address.
• Previous Sale Records: If you claimed the exclusion in the past two years.

For official forms and instructions, refer to Schedule D (Form 1040) and IRS Publication 523, Selling Your Home.

Application Process Overview

Step 1: Calculate Adjusted Basis
– Start with the purchase price of your home.
– Add the cost of improvements (such as adding a room, new roof, or remodeling).
– Subtract any depreciation claimed for business or rental use.

Step 2: Calculate Amount Realized
– Take the selling price of your home.
– Subtract selling expenses, including commissions, advertising fees, legal fees, and loan charges paid by you as the seller.

Step 3: Calculate Gain or Loss
– Subtract the adjusted basis from the amount realized.
Gain or Loss = Amount Realized – Adjusted Basis
– If the result is positive, you have a gain. If negative, you have a loss.

Step 4: Apply Main Home Exclusion
– If you qualify, exclude up to $250,000 ($500,000 for married filing jointly) of gain.
– If you do not meet the full two-year rule but qualify for a reduced exclusion, calculate the allowed amount based on the time you owned and lived in the home.

Step 5: Determine Taxable Gain
– Subtract the exclusion from your gain. Any remaining gain is taxable.
– If your gain is less than the exclusion, you owe no tax on the sale of your main home.

Step 6: Report the Sale
– Use Schedule D (Form 1040) to report the sale, even if your gain is excluded or your loss is not deductible.

Step 7: Pay Any Taxes Owed
– If you have taxable gain, apply the correct capital gains tax rate based on how long you owned the home and your income.

Practical Tips for Meeting Requirements

• Keep Good Records: Save all documents related to the purchase, improvement, and sale of your home. This will help you prove your adjusted basis and selling expenses.
• Understand What Counts as an Improvement: Only improvements that add value or extend the life of your home count toward your adjusted basis. Repairs and maintenance do not.
• Track Business or Rental Use: If you used part of your home for business or rented it out, keep clear records. You may need to separate the gain or loss for that part.
• Plan for Taxes: If your gain will exceed the exclusion, estimate your tax liability using online calculators or consult a tax professional.
• Report Even Non-Taxable Sales: The IRS requires you to report the sale of your main home on Schedule D, even if you do not owe tax.
• Consult IRS Publications: For detailed examples and worksheets, use IRS Publication 523.

Examples and Case Studies

Case Study 1: Full Exclusion
Sarah and Mike, a married couple, bought their home for $300,000 in 2018. They spent $50,000 on improvements. They sold the home in 2025 for $600,000, paying $30,000 in selling expenses.

• Adjusted Basis: $300,000 + $50,000 = $350,000
• Amount Realized: $600,000 – $30,000 = $570,000
• Gain: $570,000 – $350,000 = $220,000

Because their gain is less than $500,000, they can exclude the entire amount and owe no tax.

Case Study 2: Partial Exclusion
Anna owned her home for 18 months before selling due to a job transfer. She qualifies for a reduced exclusion.

• Maximum exclusion for single filers: $250,000
• Fraction of two years: 18/24 = 0.75
• Allowed exclusion: $250,000 x 0.75 = $187,500

If her gain is $200,000, she can exclude $187,500 and pay tax on $12,500.

Case Study 3: Loss on Sale
David bought his home for $400,000, spent $20,000 on improvements, and sold it for $380,000, paying $10,000 in selling expenses.

• Adjusted Basis: $400,000 + $20,000 = $420,000
• Amount Realized: $380,000 – $10,000 = $370,000
• Loss: $370,000 – $420,000 = –$50,000

David cannot deduct this loss because losses on the sale of a main home are not deductible.

Case Study 4: Business Use
Priya used 20% of her home as a home office. When she sells, she must pay tax on the gain related to the office portion, and only the remaining 80% may qualify for the exclusion.
