How Are Profits Taxed When I Sell My Home?

The short answer

The good news is, if you're asking this question, your home has likely grown in value while you've lived in it. That's something to feel good about. Here's the general answer: the IRS looks at your gain, which is roughly what you sold for minus your selling costs and what you have invested in the home. If the home is your main home and you meet the ownership and use tests, you may be able to exclude up to $250,000 of that gain, or up to $500,000 if you file jointly with your spouse. Gain above that is generally treated as a capital gain. What you would actually owe depends on your whole tax picture, so that answer belongs to your CPA.

Let's walk through how it generally works, so you walk into that CPA meeting knowing what to ask.

First, what counts as profit

Most people think of profit as the sale price minus what they paid. The IRS figures it a little differently, and the difference usually works in your favor.

In IRS terms, your gain is the amount realized minus your adjusted basis. Here's what those mean in plain words:

  • Amount realized is generally your sale price minus your selling expenses. The IRS lists things like a real estate agent's sales commission, advertising fees, and legal fees as selling expenses.
  • Adjusted basis starts with what you paid for the home and then goes up for improvements you made over the years.

So the number that matters isn't just your sale price. It's what's left after your costs to sell and your investment in the home are counted.

Why your improvements matter so much

If you've lived in your home for a long time, this is the part worth slowing down for. The IRS describes improvements as work that adds to the value of your home, prolongs its useful life, or adapts it to new uses. Its examples include a new roof, new siding, a deck, a patio, a fence, landscaping, a heating system, and central air conditioning.

Repairs and routine maintenance are different. The IRS says those generally can't be added to your basis, though repair-type work can count when it's part of an extensive remodel.

Generally adds to basisGenerally doesn't
A new roofPatching a leak
A new heating system or central airA routine service call
A deck, patio, or fenceRepainting a room
Landscaping or a new drivewayReplacing a broken windowpane

Here's why it matters: every receipt for a real improvement can raise your basis, and a higher basis means a smaller gain on paper. Many longtime owners have years of projects they've forgotten about. Digging out those records is one of the most useful things you can do before you sell.

The main home exclusion, in general terms

This is the rule most sellers have heard about. According to the IRS, if you sell your main home at a gain, you may qualify to exclude up to $250,000 of that gain from your income, or up to $500,000 if you file a joint return with your spouse.

To qualify, the IRS generally looks for two things in the 5 years leading up to the sale:

  1. Ownership. You owned the home for at least 24 months.
  2. Use. You lived in it as your residence for at least 24 months.

The two periods don't have to be the same 24 months, but both have to fall within the 5 years ending on the date of the sale. The IRS also describes a possible partial exclusion when the main reason for selling was a change in workplace location, a health issue, or an unforeseeable event. Whether any of that fits you is a question for your CPA.

If the home is a second or vacation home, the picture is different. We cover that in taxes when you sell a second home in Arizona.

When a gain goes past the exclusion

If your gain is larger than the exclusion, or you don't qualify for it, the IRS generally treats the gain as a capital gain. A home you've owned for more than one year is generally long-term. The IRS says long-term capital gains are taxed at 0%, 15%, or 20%, depending on your overall taxable income. Gains on property held one year or less are generally taxed as ordinary income.

And if you sell for less than you paid? The IRS says losses from the sale of personal-use property, like your home, aren't tax deductible.

We can't tell you which rate applies to you, and we won't guess. Your CPA can look at the whole picture.

What about Arizona?

Arizona has its own income tax. The Arizona Department of Revenue notes a flat tax rate of 2.5% for tax year 2023 and beyond. How a home sale gain shows up on your Arizona return, and how it fits with your federal return, is a question for your CPA, especially if you've moved here from another state or you're moving away after the sale.

Here's the part most people don't hear

The IRS tests are measured over the 5 years ending on the date of the sale. That means your closing date is part of the tax picture, not just your price. And the IRS says that if you receive a Form 1099-S for the sale, you must report it even if the gain is excludable.

That's why the best time to talk to your CPA is before you list, not after you accept an offer. A short conversation early can shape your timing in ways that are hard to change later.

Building a timeline around the answer

This is where we come in. Once your CPA has weighed in, we'll help you build a timeline for the whole sale: when to get the home ready, when to list, and a closing window that respects any date your CPA flags as important. When you can see it laid out week by week, the money side stops feeling like one big unknown.

Many of the sellers we work with in Prescott Valley and around the Quad Cities have owned their homes for decades, and some are buying their next home here too. We're Ben Zallaha and Erin Carmona with Home Team Prescott at Realty ONE Group Mountain Desert, and we can map out the sale and the next move together so the timing works for both.

What to bring to your CPA

It helps to walk in with a simple folder:

  1. Your purchase closing statement from when you bought the home.
  2. Receipts and records for improvements, like a roof, an addition, or new heating and cooling.
  3. The dates you owned and lived in the home.
  4. Any history of renting it out or using part of it for business.
  5. A realistic idea of what the home could sell for and what selling will cost.

That last item is where we're useful. It's hard for a CPA to talk about a gain without a likely sale price. Here's a look at the cost of selling a home in the Prescott area to get you started.

Frequently asked questions

Do I pay taxes when I sell my house in Prescott Valley?
It depends on your gain and whether you qualify for the main home exclusion. Many sellers who meet the ownership and use tests can exclude some or all of their gain, but only your CPA can tell you how it works for your sale.

How do I figure the profit on my home sale?
In general terms, the IRS subtracts your adjusted basis from your amount realized. That means your sale price minus selling costs, compared with what you paid plus qualifying improvements. Your CPA can help you put the real numbers together.

Do home improvements reduce capital gains?
Improvements that add value, extend the home's life, or adapt it to new uses can generally raise your basis, which lowers your gain on paper. Routine repairs generally don't count. Keep your receipts and bring them to your CPA.
