She Sold Her Phoenix Home at a $25,000 Loss, but It Won’t Lower the Taxes on Her Social Security
Selling a Phoenix home at a loss sounds like it should come with at least a tax silver lining, but the IRS treats your personal residence by a completely different rulebook, and the gap between what retirees expect and what…

More than 48% of Phoenix home listings had cut their asking prices by mid-April 2026, according to HousingWire. For a retiree who ultimately sells at a loss, the sting can come twice. She leaves the closing table with less money, then discovers the loss won’t trim the taxes on her Social Security.
Take a single retiree who bought a Phoenix house for $420,000 and now wants to move closer to her grandkids. She lists at $465,000 and eventually sells for $430,000. After accounting for a new roof and selling costs, she’s down $25,000. The loss is real. The tax break she expected isn’t.
Why a Home-Sale Loss Gets Different Treatment Than a Stock-Market Loss
When you sell a stock for less than you paid, the loss can offset gains and some ordinary income. Your house follows a different rule. If you used it as your personal home through the sale, the IRS won’t let you deduct the loss. In the eyes of the tax code, it’s personal-use property, in the same category as a car that lost value.
It also helps to know how the loss gets measured. The calculation starts with her adjusted basis: what she paid plus improvements. She paid $420,000 and added a $10,000 roof, so her basis is $430,000.
She sold for $430,000, then paid $25,000 in commissions and closing costs.
That leaves her $405,000, which is $25,000 below her basis. The $35,000 she knocked off her list price never factors into the math.
Her Social Security Tax Bill May Stay the Same
The IRS decides whether your benefits are taxable by adding one-half of your benefits to all your other income, including tax-exempt interest. Once that total, often called combined income, passes $25,000 for a single filer or $32,000 for married couples filing jointly, part of your benefit becomes taxable.
Say she collects $28,000 a year in benefits, about $2,333 a month. Half of that is $14,000.
Add $18,000 in fully taxable traditional IRA withdrawals and her combined income comes to $32,000.
That puts her $7,000 over the single threshold, so about $3,500 of her benefits gets added to her taxable income.
Even a stock loss would not let her subtract the full $25,000 from ordinary income at once. With no capital gains to offset, she could generally deduct $3,000 that year and carry the rest forward. That would bring her combined income to $29,000 and the taxable portion of her benefits to $2,000. Her personal home-sale loss provides no deduction at all, leaving $3,500 of her benefits taxable.
Where Her Sale Proceeds Can Quietly Push Taxes Higher
The bigger Social Security effect may come later, from the cash she got out of the sale. Suppose she parks $100,000 in a CD paying 4%. That produces $4,000 a year in interest, which raises her combined income to $36,000 and draws more of her benefit into the taxable column. Tax-free municipal bond interest counts in this formula too.
Inflation adds a slow squeeze. As of early October 2026, the Senior Citizens League projected a 3.5% COLA for 2027, while AARP estimated 3.6%. The $25,000 threshold has never been adjusted for inflation, so larger benefit checks can nudge more of her Social Security toward taxable territory. It is one of several subtle IRS rules that drain retirement income over time, and we mapped the rest in a free guide.
Turning the house into a rental would not make an earlier drop in value deductible. Different loss rules apply after a genuine conversion to rental use. Homeowners who sell at a profit may exclude up to $250,000 of gain, or $500,000 for married couples filing jointly, if they meet the ownership, use and other requirements.
What She Lost, and What She Never Had
It helps to keep two numbers in separate columns. The $25,000 is real money gone from her net worth, and her budget should treat it that way. The tax break she was counting on never existed, so leave it out of the plan entirely. Mixing the two together is how retirees end up surprised in April.
Where the money ends up deserves more thought than the loss itself. Before putting a six-figure check into anything that pays interest, run the combined-income math with that new interest included so you know how much more of your benefit it draws into taxable income.
The loss on her house gives her no tax break. What she earns on the money left over can still give the IRS more to count.
