Will You Owe Capital Gains Tax When You Sell Your Southern NH Home?

If you are selling your main home in Southern New Hampshire, you may be able to exclude up to $250,000 of gain from federal income, or up to $500,000 if you are married filing jointly and meet the applicable tests. The key word is gain. Your taxable gain is not the sale price and it is not automatically the check you receive at closing.

For many homeowners, the exclusion covers the entire gain. Others need a closer review because they recently bought the home, used it as a rental, claimed depreciation, inherited it, received it in a divorce, or sold another primary residence within the prior two years. Before you choose a listing date or commit your sale proceeds to the next home, get a tax estimate based on your actual records.

This is general real estate education, not tax or legal advice. A REALTOR® can help you estimate selling costs and plan the transaction, but a qualified tax professional should determine your basis, exclusion, reporting requirements, and tax due.

First, capital gain is not the same as sale price

The IRS starts with your selling price, subtracts eligible selling expenses to determine the amount realized, and then subtracts your adjusted basis. The result is your gain or loss.

Selling price − eligible selling expenses = amount realized
Amount realized − adjusted basis = gain or loss

Suppose you bought a home for $350,000, added $60,000 of qualifying capital improvements, sold it for $700,000, and had $45,000 of eligible selling expenses. In this simplified illustration, the amount realized is $655,000 and the adjusted basis starts at $410,000, producing a $245,000 gain before any other basis adjustments. A qualifying single seller might be able to exclude all of that gain. The same seller should not assume the answer without checking the complete basis and eligibility rules.

How the $250,000 or $500,000 exclusion works

IRS Topic No. 701 explains that a qualifying taxpayer may exclude up to $250,000 of gain from the sale of a main home. The limit may be up to $500,000 for a married couple filing jointly when the joint-return requirements are satisfied.

In general, the seller must meet both an ownership test and a use test during the five-year period ending on the sale date. For a single filer, that usually means owning the home and using it as a main residence for at least 24 months during those five years. The ownership and use periods do not have to be the same 24 months.

For a married couple filing jointly, either spouse generally must meet the ownership test, while both spouses must meet the use test individually to qualify for the full $500,000 limit. The IRS also applies a look-back rule. Generally, you are not eligible for the exclusion if you excluded gain from another home sale during the two years before this sale.

What if you have not lived there for two full years?

Do not assume the entire gain is taxable. IRS Publication 523 provides for a possible partial exclusion when the primary reason for the sale is a qualifying work-related move, health-related move, or unforeseeable event. The details matter, including the timing, the people involved, and whether a regulatory safe harbor or the broader facts-and-circumstances test applies.

This is one reason the projected closing date can matter. If you are close to satisfying a 24-month test, a tax professional can explain whether changing the timing is useful and practical. Tax planning should inform the real estate plan, but it should not cause you to ignore a necessary move, carrying costs, or current market conditions.

Your adjusted basis may be higher than the original purchase price

Sellers often remember what they paid but overlook improvements made over many years. Qualifying capital improvements can increase basis and may reduce gain. Examples commonly include additions, a new roof, major system replacements, central air conditioning, and certain substantial property improvements. Ordinary repairs and maintenance generally do not increase basis unless they are part of a larger qualifying improvement project.

Keep invoices, contracts, proof of payment, permit records, and before-and-after documentation when available. If you replaced a component that had previously been added to basis, special adjustments may be required. Energy credits, insurance reimbursements, casualty events, assessments, depreciation, and other items can also affect basis. Publication 523 includes worksheets and detailed categories, but it cannot reconstruct missing records for you.

Rental use, a home office, and depreciation need special attention

If you rented the home, operated a business from it, or claimed home-office depreciation, ask a tax professional to review the sale before you list. The home-sale exclusion does not apply to gain equal to depreciation allowed or allowable for periods after May 6, 1997. IRS guidance also contains allocation and nonqualified-use rules that may apply when part of the property was separate from the living area or when the entire home had periods of nonresidential use.

The phrase allowed or allowable is important. Skipping a depreciation deduction in an earlier year does not necessarily prevent the basis adjustment later. Bring prior tax returns and depreciation schedules to the tax conversation instead of relying on memory.

Inherited, gifted, or divorce-related property can have a different basis

A home received as a gift generally starts with information tied to the donor’s adjusted basis, subject to exceptions. An inherited home commonly uses fair market value at the date of death or an alternate valuation date when properly elected. Property transferred between spouses or former spouses incident to divorce has its own rules. These are not situations for a quick online calculator.

If the home was inherited, bring the estate appraisal, probate records, closing documents, and any federal estate tax return information. If it came through a divorce, bring the settlement agreement, deed, prior purchase records, and improvement documentation. A defensible basis can materially change the tax estimate.

Do you have to report the sale?

According to IRS Topic No. 701, you generally must report the sale if you receive Form 1099-S or if you cannot exclude all of the gain. When reporting is required, Form 8949 and Schedule D may be involved. Publication 523 also explains that a loss on the sale of a personal residence is not deductible.

The closing company’s handling of Form 1099-S does not decide whether you owe tax. Likewise, having no taxable gain does not always mean there is no reporting obligation. Give your closing documents to the tax professional who prepares the return for the year of sale.

A practical pre-list tax checklist

  • Find the original purchase closing statement and deed.
  • Gather receipts and permits for major improvements.
  • Locate records for casualty losses, insurance payments, energy credits, or special assessments.
  • Collect prior tax returns and depreciation schedules if the property was rented or used for business.
  • Document any inheritance, gift, trust, divorce, or ownership changes.
  • Estimate likely sale price and seller closing expenses with your REALTOR®.
  • Ask a tax professional to review the projected gain before you commit the proceeds elsewhere.

How this affects your selling strategy

A sound tax estimate helps answer practical real estate questions. Can you comfortably fund the next purchase? Does the closing date matter? Should you complete a planned improvement, or will it cost more than it adds in market value and basis benefit? How much cash should remain available after closing until the return is filed?

The goal is not to let taxes frighten you out of a good move. It is to prevent a surprise after the proceeds have already been spent. I help Southern New Hampshire sellers build a realistic net sheet, organize the transaction timeline, and coordinate questions with their attorney, lender, and tax professional so each expert stays in the right lane.

Frequently Asked Questions

Is the first $250,000 of my sale price tax-free?

No. The exclusion applies to qualifying gain, not gross sale price. Gain is calculated from amount realized and adjusted basis.

Do married sellers automatically receive a $500,000 exclusion?

No. A joint return and the applicable ownership, use, and look-back requirements must be satisfied. Individual circumstances can reduce the available exclusion.

Can renovations reduce my taxable gain?

Qualifying capital improvements may increase adjusted basis. Routine maintenance usually does not. Keep records and have a tax professional classify the expenses.

What if I converted my Southern NH home to a rental?

You may still qualify for some home-sale exclusion, but depreciation and nonqualified-use rules can make part of the gain taxable. Review the history before setting expectations.

Can I deduct a loss on my primary home?

Generally, no. IRS Publication 523 states that a loss on the sale of a personal residence is not deductible.
