Taxes When Selling a Lake Home in Iowa
Selling an Okoboji lake home, cabin or second home? Here are the taxes Iowa sellers run into, from capital gains and the transfer tax to property tax prorations and inherited property.

When you sell a home in Iowa, expect the state transfer tax ($0.80 per $500 of price above $500, usually paid by the seller), a property tax proration at closing, and possibly federal and Iowa tax on your gain. A main home may qualify for the federal $250,000 or $500,000 exclusion, but most lake cabins and second homes do not. Iowa taxes income, including gains, at a flat 3.8% beginning with tax year 2025.
1. Capital Gains on a Second Home or Lake Cabin
Your gain is roughly the sale price, minus selling costs, minus what you paid and what you have put into the property in improvements. Keep receipts for things like a new roof, a seawall, a dock system or an addition; they can reduce your gain.
Federally, gains on property held more than a year are taxed at long-term capital gains rates, and higher-income sellers may also owe the 3.8% net investment income tax. Iowa taxes the gain as part of your income at its flat rate.
2. The Home-Sale Exclusion
If the property was your main home for at least two of the last five years, you may be able to exclude up to $250,000 of gain ($500,000 for married couples filing jointly) from federal tax. That is why the same sale can be taxed very differently for a year-round resident of Spirit Lake or Milford than for a family selling a summer cabin.
3. Iowa’s Capital Gain Deduction
Iowa has a special capital gain deduction, but it is narrow. It mainly applies to certain business and farm property that meets holding-period and material participation requirements. It generally does not apply to a personal lake home or cabin. Ask your tax professional before counting on it.
4. Iowa Real Estate Transfer Tax
Iowa charges $0.80 for every $500 of the sale price above the first $500. The seller customarily pays it, although it can be negotiated.
| Sale price | Approx. transfer tax |
|---|---|
| $300,000 | $479.20 |
| $500,000 | $799.20 |
| $1,000,000 | $1,599.20 |

5. Property Tax Proration
Iowa property taxes are paid in arrears, so at closing the seller typically credits the buyer for taxes that have built up but have not been paid yet. It is not an extra tax, but it does reduce what you walk away with, so include it when you compare offers.
6. Inherited Property
Iowa repealed its inheritance tax for deaths on or after January 1, 2025. Inherited property also usually receives a stepped-up basis to its value at the date of death, so heirs who sell soon after often have little or no gain. See selling an inherited home or cabin.
7. Rented Cabins and Investment Property
If you rented the cabin out, depreciation you took (or could have taken) may be “recaptured” and taxed when you sell. Investment property may also qualify for a 1031 exchange, which can defer tax if you buy another investment property. Both need planning before the sale, not after.
8. Selling From Another State
A gain on Iowa real estate is generally Iowa-source income, so out-of-state owners may need to file an Iowa return. Your home state may tax it too, often with a credit for tax paid to Iowa. See selling from out of state.
Before you list: ask your tax professional to estimate your gain and tax, and bring George your timeline. Sometimes when you close, or whether it is your main home by then, makes a real difference.

Frequently Asked Questions
Do I pay capital gains tax when I sell my Okoboji lake home?
If it is a second home, usually yes on any gain, because the federal home-sale exclusion generally applies only to your main home. Iowa also taxes the gain as income at its flat rate, which is 3.8% beginning with tax year 2025. A tax professional can estimate your actual amount.
What is the Iowa real estate transfer tax?
Iowa charges $0.80 for every $500 of the sale price above the first $500. On a $500,000 sale that is about $799. In Iowa it is customarily paid by the seller, though it is negotiable.
Does the $250,000 home-sale exclusion apply to a lake cabin?
Only if the cabin was your main home for at least two of the five years before the sale. Most second homes and summer cabins do not qualify.
Does Iowa have an inheritance tax?
Iowa repealed its inheritance tax for deaths on or after January 1, 2025. Inherited property also usually gets a stepped-up tax basis, which can reduce gain on a sale.
I live in another state. Do I owe Iowa tax?
A gain on Iowa real estate is generally Iowa-source income, so you may need to file an Iowa return even if you live elsewhere. Your home state may also tax it and allow a credit. Ask your tax professional.
