Capital gains tax: the starting point for a home sale
A sale price, the money left after paying off a mortgage, and taxable gain are different numbers. Begin with the amount realized from the sale and the property's adjusted tax basis. A qualifying main-home exclusion may then reduce the gain included in income. Rental, business and mixed-use properties need additional analysis.
These rules apply to sellers in Farmington Hills, Novi, Northville, Bloomfield Hills and other Oakland County communities. A city's home prices or a property's waterfront location do not establish your exclusion or tax rate.
Who may qualify for the main-home exclusion?
According to IRS Topic 701, eligible sellers may exclude up to $250,000 of gain, or up to $500,000 on a qualifying joint return. These are limits on gain, not on the home's sale price.
The usual tests involve owning and using the home as your main residence for at least two of the five years before the sale, plus limits on using the exclusion for another sale in the preceding two years. For the full joint-return exclusion, either spouse generally must meet ownership requirements and both must meet the use requirements. Other conditions and exceptions apply.
Some sales related to work, health or unforeseen circumstances may qualify for a reduced exclusion. Do not assume every early move qualifies. Review the dates and circumstances with your adviser before setting a closing date.
How do sale proceeds and adjusted basis affect the calculation?
Keep purchase and closing records, improvement invoices, and any rental or business-use records. Basis may increase for qualifying improvements and decrease for depreciation or other required adjustments. Ordinary upkeep does not automatically increase basis. Gifts, inheritances and prior exchanges have additional rules; see IRS Publication 551.
Illustration only: if the amount realized after eligible selling expenses is $700,000 and adjusted basis is $400,000, the gain before an exclusion is $300,000. A seller eligible for a $250,000 exclusion could have $50,000 remaining before other applicable rules. The mortgage payoff does not replace adjusted basis in this calculation. This example does not estimate anyone's tax bill.
| Record | Why it matters |
|---|---|
| Purchase and sale statements | Support basis, sale proceeds and transaction expenses. |
| Improvement invoices | Help identify qualifying basis adjustments. |
| Occupancy and prior-sale dates | Help evaluate exclusion eligibility and timing. |
| Rental and depreciation records | Support analysis of business use and depreciation-related gain. |
Does Michigan tax gain excluded on the federal return?
Michigan starts with federal adjusted gross income and applies state additions and subtractions, under Michigan’s taxable-income definition in MCL 206.30. A valid federal home-sale exclusion generally keeps that excluded gain out of this starting amount. It is misleading to say Michigan automatically taxes the same gain merely because the federal exclusion was used.
Taxable gain, state adjustments, residency and filing obligations still require review. Ask your adviser to prepare the federal and Michigan calculations together. This discussion concerns income tax on a sale; annual property taxes and transfer taxes are separate items.
What changes for a rental or former rental home?
A property used only as an investment does not qualify for the main-home exclusion simply because it is residential real estate. A former home or mixed-use property may have a different outcome. Prior rental use does not automatically disqualify every dollar of gain, and moving into a rental for two years does not guarantee a full exclusion.
Periods of nonqualified use after 2008 can affect the allocation of gain, but there are exceptions. Depreciation attributable to periods after May 6, 1997 also needs separate treatment. IRS Publication 523 explains the main-home and business-use rules.
For qualifying long-term capital gains, federal rates are generally 0%, 15% or 20%, depending on taxable income and other rules. Gain connected to depreciation can be treated differently. Unrecaptured Section 1250 gain has a maximum 25% federal rate; some recapture can instead be ordinary income. A blanket statement that every rental-sale gain or all recapture is taxed at 25% is inaccurate. Review IRS Topic 409 and Publication 544 with your adviser.
When can the 3.8% Net Investment Income Tax apply?
For individuals, NIIT generally equals 3.8% of the smaller of net investment income or modified adjusted gross income above the applicable threshold. Thresholds include $200,000 for single or head-of-household filers, $250,000 for married filing jointly, and $125,000 for married filing separately. Crossing a threshold does not automatically impose 3.8% on the entire sale price or entire gain.
Gain validly excluded under Section 121 is not included in net investment income. See the IRS NIIT questions and answers for details.
Can an investor use a Section 1031 exchange?
A qualifying exchange can defer recognition of gain on eligible investment or business real property. Buying another property after an ordinary sale is not enough, and a main home does not qualify merely because the proceeds are reinvested.
In a typical deferred exchange, replacement property generally must be identified within 45 days, and received by the earlier of 180 days or the tax-return due date, including extensions. Engage a qualified intermediary and tax adviser before transferring the property; handling proceeds incorrectly can prevent deferral. Cash or other nonqualifying property received may create taxable gain. Review the IRS like-kind exchange guidance and Publication 544.
Plan the sale and the tax review together
Before listing, assemble your records and ask your adviser what facts could change the calculation. Then coordinate your preferred sale date with preparation, pricing, occupancy and your next move. Tom can help review relevant local sales and transaction timing; your adviser determines the tax treatment.

Frequently asked questions
Is the exclusion based on my home's sale price?
No. The exclusion applies to qualifying gain, not the gross selling price. Your adviser first determines the gain and then evaluates the exclusion.
Does rental use always prevent a home-sale exclusion?
No. Former residence and mixed-use situations need individual review of occupancy, nonqualified use, depreciation and the other eligibility rules.
Does buying another home automatically avoid capital gains tax?
No. A main-home exclusion depends on eligibility, and an investment-property exchange has separate requirements. Reinvesting proceeds alone does not establish either result.
Can Tom calculate my tax liability?
Tom helps with the real estate sale, market information and transaction coordination. A qualified tax adviser should determine your basis, exclusion, tax liability and filing requirements.
