Quick answer: There’s no deadline to sell your old home or to buy a new one. To exclude up to $250,000 of profit ($500,000 for married couples filing jointly) from federal capital gains tax, you need to have owned the home and lived in it as your main home for at least 2 of the 5 years before the sale. In practice, that means you generally have up to 3 years after you move out to sell and still qualify, as long as you lived there at least 2 years before moving. Nevada has no state income tax, so for most sellers in Las Vegas, Henderson, North Las Vegas and Boulder City, federal tax is the only concern.

Where the "Sell Within 2 Years" Myth Comes From
Many homeowners remember a rule that you had to buy a new, more expensive home within two years to avoid paying tax on a sale. That was the old “rollover” rule, and it ended with the Taxpayer Relief Act of 1997.
Today’s rule, found in Section 121 of the tax code, works differently. You don’t have to buy another home at all. You can downsize, rent, move in with family or put the money in the bank. What matters is how long you owned and lived in the home you’re selling, and how long ago you moved out.
The 2-Out-of-5-Year Rule, Explained
To claim the full exclusion, you need to pass three tests, according to IRS Publication 523:
- The ownership test. You owned the home for at least 24 months during the 5 years before the sale.
- The residence test. You lived in the home as your main home for at least 24 months (730 days) during those same 5 years. The months don't have to be in a row, and short absences like vacations still count as time you lived there.
- The look-back test. You haven't used the exclusion on another home sale in the 2 years before this one.
For married couples filing jointly, only one spouse has to meet the ownership test, but both spouses must meet the residence test to claim the full $500,000. If only one qualifies, the couple may still exclude up to $250,000.
So How Soon Do You Need to Sell?
Because the IRS looks back 5 years from the date you sell, your window to sell starts shrinking the day you move out. The longer you lived in the home first, the more time you have, up to a maximum of 3 years.
- Lived there 5 years or more: You can move out and still have up to 3 years to sell with the full exclusion.
- Lived there 3 years: You have about 1 year after moving out before you drop below 2 years of residence in the 5-year window.
- Lived there exactly 2 years: You need to sell right away, because every month after you move out pushes some of your residence time outside the window.
- Lived there less than 2 years: You won't qualify for the full exclusion, but you may qualify for a partial one (see below).
Example: A couple lived in their Henderson home for 8 years, then bought a new home in Boulder City and moved in March 2026. They can sell the Henderson home any time before March 2029 and still exclude up to $500,000 of profit. If they wait until April 2029, they’ll have lived there less than 2 of the 5 years before the sale and could owe tax on the entire gain.
How to Figure Your Gain
Your taxable gain isn’t simply the sale price minus what you paid. The IRS lets you adjust both sides of the math:
- Start with the amount you realize: your sale price minus selling expenses, such as real estate commissions, title and escrow fees and certain closing costs.
- Subtract your adjusted basis: what you paid for the home, plus certain buying costs, plus the cost of improvements like a new roof, pool, room addition or kitchen remodel. Routine repairs and maintenance don't count.
- The difference is your gain. If it's below your $250,000 or $500,000 exclusion and you qualify, you generally owe no federal tax on it.
This is why it pays to keep receipts for every major improvement. Many Las Vegas valley homeowners who bought years ago have seen large price gains, and documented upgrades can make the difference between owing tax and owing nothing.
What Happens if Your Gain Is Over the Limit
Any gain above your exclusion is taxed as a long-term capital gain if you owned the home more than a year. Federal long-term capital gains rates are 0%, 15% or 20%, depending on your taxable income. Higher-income sellers may also owe the 3.8% net investment income tax on the taxable portion.
The good news for Southern Nevada sellers is that Nevada doesn’t have a state income tax, so there’s no state capital gains tax on top of the federal amount. Sellers moving here from states like California often find this one of the biggest differences when they eventually sell.
Moved Before 2 Years? You May Still Get a Partial Exclusion
If you sell before meeting the 2-year tests, you may still exclude part of your gain if the main reason for selling was one of these:
- A job change. For example, a new job at least 50 miles farther from your home than your old workplace.
- A health reason. Moving to get treatment, or to care for a family member with an illness or injury.
- An unforeseeable event. Such as divorce, job loss, a death in the family, a natural disaster or a multiple birth from one pregnancy.
The partial exclusion is based on how much of the 2 years you completed. If you lived in the home for 12 months before a qualifying job move, for example, you could generally exclude up to half the full amount: $125,000 for a single filer or $250,000 for a married couple.
Renting Out Your Old Home Before Selling
A lot of homeowners in Las Vegas, Henderson and North Las Vegas buy their next home first and rent out the old one for a while. That can work well, but it changes the tax picture:
- The 3-year clock still applies. Once you move out, the time you rent the home counts against your 5-year window. Rent it too long and you lose the exclusion.
- Depreciation is taxed when you sell. Any depreciation you claimed, or were allowed to claim, while it was a rental can't be excluded. It's "recaptured" and taxed even if the rest of the gain is tax-free.
- Rental before you lived there can reduce the exclusion. If the home was a rental or second home before you moved in, and that period was after 2008, part of your gain may not qualify.
- A 1031 exchange is a different tool. If you keep the home as a rental long-term, you may be able to defer tax by exchanging it for another investment property under different rules. That's a conversation for your CPA.
Special Situations
- Military and certain government service. Members of the uniformed services, foreign service and intelligence community on qualified extended duty can suspend the 5-year window for up to 10 years. That's helpful for families stationed at Nellis Air Force Base or reassigned elsewhere.
- Surviving spouses. A surviving spouse may still claim the $500,000 exclusion if the home is sold within 2 years of the spouse's death and other conditions are met.
- Divorce. If a former spouse continues living in the home under a divorce or separation agreement, the spouse who moved out may be able to count that time as their own use.
- Inherited homes. A home you inherit generally gets a "stepped-up" basis to its value at the date of death, which can reduce or eliminate the gain when you sell, even if you never lived there.
Proposed Changes: The "No Tax on Home Sales Act"
You may have seen headlines about eliminating capital gains tax on home sales. The No Tax on Home Sales Act was introduced in Congress in July 2025 and would remove the tax on the sale of a primary home. As of mid-2026, it had not passed and was still in committee, so the current $250,000 and $500,000 limits still apply. It’s worth watching, but don’t plan a sale around a bill that isn’t law.
Planning Your Sale With Taxes in Mind
- Mark your move-out date. Count forward 3 years and treat that as your outside deadline if you lived there at least 2 years.
- Gather your records. Purchase documents, closing statements and receipts for improvements all help establish your basis.
- Get a realistic value. Knowing what your home will likely sell for tells you whether you're anywhere near the exclusion limit.
- Talk to a CPA before you list. Especially if you've rented the home, used part of it for business, or expect a gain over the limit.
- Leave time to sell. Homes across the valley are taking longer to sell than a year or two ago. Don't wait until the last few months of your window to list.
Inside your window
Sold within 3 years of moving out, after living there at least 2 of the last 5 years: up to $250,000 or $500,000 of gain is generally tax-free.
Outside your window
Sold after the window closes, or with too little time lived there: the gain may be fully taxable, unless a partial exclusion applies.
