Sell your Utah home and keep more profit. How the federal $250k/$500k exclusion, basis, improvements, and partial exclusions work under IRS rules.
Most Utah sellers do not pay federal capital gains tax on their home sale. That is because the IRS lets you exclude a chunk of profit if you owned and lived in the house. The trick is knowing what counts as profit and whether you actually qualify.
The federal rule is simple to state and easy to mess up on details. If you owned and used your home as your main home for at least 2 of the last 5 years, you can generally exclude up to $250,000 of gain if single, and up to $500,000 if married filing jointly. That summary comes straight from the IRS overview of the sale of your residence.
Gain is not your sale price. Gain is your sale price minus your adjusted basis and minus certain selling expenses. Basis is what you paid plus improvements, not repairs. Selling expenses include things like commissions and other closing costs that the IRS allows you to subtract. We will break those down below.
If you have never read it, Publication 523 is the plain-language instruction manual for this. The IRS Publication 523, Selling Your Home, Publication 523 walks through the ownership test, use test, and all the weird exceptions.
For your pricing math, keep the tax math separate. See How to Price a Utah Home Without an Agent so you do not bake a guess about taxes into your list price.
Publication 523 defines two clocks. Both look back from the sale date.
Ownership test: You owned the home for at least 2 years in the 5-year period ending on the date of sale. It does not have to be continuous.
Use test: You used the home as your main home for at least 2 years in that same 5-year period. Again, it does not have to be continuous.
A few wrinkles that catch FSBO sellers:
If you moved for work, health, or an unforeseeable event, you might qualify for a partial exclusion even if you fall short on time. That is covered in Publication 523 under exceptions and worksheets. Do not guess. Run the worksheet and talk to a tax pro.
Here is where people either overpay or create problems.
Your adjusted basis starts with what you paid for the home. Then add:
It does not include routine maintenance and repairs that just keep things working. Repainting the same walls, fixing a leaky faucet, or patching drywall is generally not an addition to basis.
Checklist to build your basis file:
Selling expenses reduce your amount realized. Per IRS guidance, commissions, certain closing costs, and costs to get the property ready for sale under specific rules can reduce gain. Your title company and Publication 523 list what counts. For a clean view of what you will see on the settlement statement, skim Utah FSBO Seller Closing Costs, Line by Line and Choosing a Title Company for a Utah FSBO Sale.
Worked example, simplified: You bought for $400,000. You added a $40,000 addition and a $12,000 new furnace. Your adjusted basis is $452,000. You sell for $625,000 and pay $30,000 in eligible selling expenses. Amount realized is $595,000. Gain is $595,000 minus $452,000, or $143,000. If you are single and meet tests, you can exclude the full $143,000 and owe no federal capital gains tax on that sale. If married filing jointly, same result. If gain were $550,000 for joint filers, you would exclude $500,000 and pay tax on $50,000.
Forms change and inflation adjustments happen, so confirm the numbers with current IRS materials and a tax advisor.
Life rarely fits the 2-out-of-5 box perfectly. Here are common complications for Utah sellers:
Partial exclusion: If you sold because of a job move more than 50 miles, a serious health reason, divorce, or other IRS-defined unforeseeable events, you may qualify for a prorated exclusion. Publication 523 has the worksheet. Document the reason with letters, medical notes, or employer notices.
Rental periods: If you rented the home after moving out, you still do the ownership and use lookback. But past depreciation taken after May 6, 1997 may be taxable and cannot be excluded. The IRS overview of residence sales flags this. Keep your old returns that show depreciation.
Home office or business use: If you claimed depreciation for a home office, that portion may be taxable. If you used a detached structure or part of the home exclusively for business, allocation gets more complex. Again, Publication 523 covers it.
Two homes: You can only have one main home at a time. Factors include where you live most of the time, where you work, bank, vote, and claim residency. Do not try to flip the label in the year of sale.
If you are sorting disclosures while you sort taxes, this pairs well with The Utah FSBO Seller Disclosure Checklist and the details in The Utah REPC, Explained for FSBO Sellers. Getting days right there matters for taxes too, so also note Utah Due Diligence Deadlines Without the Drama.
Next step: Pull your original closing disclosure, list improvements with receipts, and run the Publication 523 worksheet. If you had rental time, home office depreciation, or a short ownership period, take those papers to a tax professional before you set your net proceeds goal. Start with the Utah FSBO guide to keep the rest of your sale orderly.
