How Does Selling an Inherited House Work for Taxes in Indiana?

How Does Selling an Inherited House Work for Taxes in Indiana?

In our experience on the Southside and in Johnson County, the tax question is the one that keeps heirs up at night, and it is usually the smallest problem in the sale. Parents who bought a Greenwood ranch in the 1990s often feel they are sitting on a huge taxable gain. Federal law resets that starting point at death. This guide walks through how the rules work, who reports what, and where the exceptions are. It is general information, not tax advice, and we will say more than once: bring your CPA in early.

Do you owe tax just for inheriting a house in Indiana?

Usually not. Indiana's inheritance tax does not apply to property from anyone who died after December 31, 2012, under IC 6-4.1-1-0.5. The federal estate tax only reaches estates above the basic exclusion amount, which the IRS lists as $15,000,000 for deaths in 2026. For most Central Indiana families, the more common tax question is income tax when the house sells.

That distinction matters. Inheriting is not the same as selling. Selling can create taxable gain, but only if the sale price, after selling expenses, is higher than your adjusted basis. Because of the stepped-up basis, that gap is often much smaller than heirs expect.

Property taxes are separate. The Johnson County or Marion County tax bill keeps coming while the house sits, and it is paid in arrears in spring and fall installments. Someone has to keep paying it, along with insurance and utilities, until closing. We covered those first-60-days tasks in our earlier post on what to know before you sell an inherited house in Indiana.

What is a stepped-up basis, and why does it matter so much?

A stepped-up basis means the heir's starting value for tax purposes is the home's fair market value on the date of death, not the price the owner originally paid. IRS Publication 551 (December 2025) explains this rule. It can erase decades of appreciation, so an heir who sells soon after death often reports little or no gain.

Here is why that is such a big deal in our market. A house bought in Greenwood or Perry Township twenty-five years ago may have tripled in price. If the heir had to use the parent's original purchase price, the taxable gain could be large. With the step-up, only the change in value after the date of death generally counts toward the gain.

Two details in Publication 551 are worth knowing:

• Alternate valuation date. If the estate files a federal estate tax return (Form 706), the personal representative may choose an alternate valuation date six months after death. Most Central Indiana estates never file Form 706, so the date of death is the usual anchor.
• Consistent basis. When a Form 706 is filed, beneficiaries generally receive a Schedule A of Form 8971 reporting the estate tax value, and some heirs must use that value as their basis.

The step-up only helps if you can show what the house was worth on that date. That is why we wrote a separate guide on whether heirs need a date-of-death appraisal in Indiana. Short version: a credible, dated value is the backbone of the whole tax picture.

How is the gain figured when you sell an inherited house?

The gain is generally the sale price, minus selling expenses, minus your adjusted basis. Your adjusted basis starts at the date-of-death value and can increase for qualifying capital improvements you make before selling. Under 26 U.S.C. §1223(9), any gain is treated as long-term, even if you close within a year of the death.

Put simply, the calculation has three parts:

1. Amount realized. The contract price minus qualifying costs of selling, such as agent compensation, title charges and seller-paid items shown on your closing statement.
2. Adjusted basis. The date-of-death value, plus qualifying improvements that add value or extend the home's life, such as a new roof or furnace. Routine cleaning and minor touch-ups generally do not count as improvements.
3. Gain or loss. Amount realized minus adjusted basis.

Because the gain is long-term, it is taxed at federal long-term capital gains rates, which depend on the heir's total income. Indiana then taxes the applicable net gain as part of adjusted gross income at the state rate, which IC 6-3-2-1 sets at 2.95% for 2026 and 2.9% for 2027, plus county income tax where applicable.

What if the house sells for less than the date-of-death value? Whether that loss is deductible depends on how the house was used after death. IRS Publication 544 says losses on personal-use property are not deductible. If no heir used the house personally, the answer can be different. This is a question for your CPA, not a guess.

To get real numbers for the amount-realized line, ask for a written seller net sheet. Our post on what goes into a seller net sheet in Indiana explains each line.

Who reports the sale, the estate or the heirs?

It depends on whose name is on the deed at closing. If the personal representative sells the house on behalf of the estate, the sale is generally reported on the estate's fiduciary income tax return. If the house was deeded to the heirs first, each heir generally reports their share on Form 8949 and Schedule D of their own return.

Either way, the title company handling the closing will usually issue Form 1099-S, Proceeds From Real Estate Transactions. IRS Publication 523 notes the date of sale appears in box 1 of that form. Receiving a 1099-S does not mean you owe tax. It means the sale was reported, and your return shows the basis and applicable expenses that determine the gain.

In our experience, the cleanest estate sales in Johnson County have three things lined up before listing:

• Clear authority to sign, such as letters from the probate court, a transfer-on-death deed, or all heirs being on title.
• A written date-of-death value in the file.
• A CPA or estate attorney who knows the closing date is coming.

When several siblings inherit together, the reporting generally follows their ownership shares. That is also the point where families sometimes decide one person should keep the house. We cover that path in can one heir buy out the others on an inherited Indiana home.

How do the tax rules change depending on the situation?

The basic rule, a stepped-up basis and long-term treatment, covers many inherited homes. The details can change when a surviving spouse owned the house jointly, when an heir moves in, when the house was gifted before death, or when the estate is large enough to file Form 706.

If children inherit through a will or probate, the general starting basis is the home's fair market value on the date of death. If the property is sold soon afterward, the gain may be relatively small.

A beneficiary who receives the property through a transfer-on-death deed generally has a date-of-death value as the starting basis as well. Avoiding probate does not eliminate the need to document the property's value.

A surviving spouse who owned the property jointly can have a different basis calculation. Generally, the deceased spouse's share may receive a step-up while the surviving spouse's share keeps its existing basis, depending on how the property was owned and the applicable federal rules. A surviving spouse may also qualify for up to a $500,000 home-sale exclusion in certain circumstances if the property is sold within two years of the death and the applicable requirements are met.

If an heir moves into the inherited house, the starting basis is still generally the date-of-death value. However, if the heir owns and uses the property as a main home for at least 24 months during the five years before the sale, the heir may qualify for the $250,000 home-sale exclusion, or up to $500,000 for qualifying married couples filing jointly.

A house that was gifted to a child before the owner's death is different. Property transferred during the owner's lifetime generally does not receive the same stepped-up basis as property inherited at death. The recipient's basis may instead be tied to the donor's basis under the applicable gift rules. If your family transferred the house before death, talk with your CPA and estate attorney before listing.

Finally, if the estate files Form 706, the estate tax value reported through Form 8971 can become important when determining the beneficiary's basis. The consistent-basis rules may require the beneficiary to use the value reported by the estate.

The gift situation is one that surprises families. Deeding a house to a child years before death may avoid probate, but it can also mean giving up the step-up that would have applied if the property were inherited at death. Get professional advice before making that decision.

What does this look like in Central Indiana?

Here is a hypothetical Greenwood example. The numbers are made up to show the math, not a prediction for any house. For context, the Indiana REALTORS Housing Data Hub reported a Johnson County median sales price of $330,000 in August 2026, down 6% from a year earlier, with a median of 24 days on market.

Say a mother bought a three-bedroom ranch in Greenwood in 1998 for $120,000. She dies in January 2026. A licensed appraiser sets the date-of-death value at $310,000. Her two children replace the water heater, clean the house out, and sell it in September 2026 for $320,000.

With the applicable step-up, the starting basis is $310,000. That means the initial difference between the sale price and basis is $10,000 before considering qualifying selling expenses and capital improvements.

The original $120,000 purchase price generally is not the starting basis for the inherited property. Using that old purchase price would create a $200,000 difference before expenses, which shows why the date-of-death value matters so much.

After selling expenses come out, the actual taxable gain may be considerably smaller. If qualifying improvements increased the basis, that can reduce the gain further.

Carrying costs matter too. While an inherited house is waiting to sell, the estate or heirs may continue paying property taxes, insurance, utilities, maintenance and other expenses. Every month the property sits vacant can add to the cost of holding it.

When does this information not apply?

This guide is most useful for a straightforward inherited residential property. Some situations require more detailed tax analysis.

• Rental or business property. Depreciation, passive losses and Form 4797 reporting can apply.
• Trust-owned homes. A home held in a revocable or irrevocable trust follows the applicable trust terms and tax rules.
• Out-of-state heirs. Your home state may tax the gain differently. Ask your CPA how your state treats the sale.
• Disputes among heirs. If siblings cannot agree on selling, the estate attorney should help resolve the ownership and authority issues first.

What should you do before selling an inherited house?

If you have inherited a house in Greenwood, Franklin, Southside Indianapolis or Bloomington, start with three steps.

First, ask for a written market analysis tied to the date of death, and discuss with your CPA whether a formal appraisal is needed.

Second, ask for a written seller net sheet so you can understand your likely proceeds after the mortgage, taxes, selling costs and other closing expenses.

Third, confirm who has authority to sign. Depending on the situation, that could be the personal representative, trustee, transfer-on-death beneficiary or the heirs who now hold title.

Gather the deed, probate documents, death certificate, mortgage information, property tax records, date-of-death valuation and receipts for qualifying improvements before the sale.

Frequently asked questions

Does a 1099-S mean I owe tax on the inherited house?

No. Form 1099-S reports that a real estate sale happened and the gross proceeds. Your tax return then considers your stepped-up basis and applicable selling expenses, which may reduce the reportable gain to little or nothing. Keep the 1099-S, closing statement and valuation together for your CPA.

Do repairs before the sale lower the tax on an inherited house?

Capital improvements, such as a new roof, furnace or water heater, generally add to your basis and can reduce gain. Routine repairs and cleaning usually do not. Keep receipts for everything you pay between the date of death and closing, and let your CPA determine which expenses qualify.

What if I move into the inherited house before selling it?

If you own and live in the house as your main home for at least 24 months within the five years before the sale, you may qualify for the home-sale exclusion under IRS Publication 523: up to $250,000, or $500,000 for married couples filing jointly. Your starting basis is still generally the date-of-death value.

Does the mortgage have to be paid off as soon as the owner dies?

Generally no. Federal law, 12 U.S.C. §1701j-3(d), provides protections for certain residential transfers after a borrower's death. Payments still need to be made. When the house sells, the remaining mortgage balance is generally paid from the proceeds at closing.

Do heirs keep paying property taxes until the house sells in Indiana?

Yes. Indiana property taxes are billed in arrears and paid in spring and fall installments. The estate or heirs generally continue paying them until closing, when the title company prorates taxes between the seller and buyer.

Can the estate sell the house before probate closes?

Often yes. A personal representative with the proper authority can generally sign a listing and deed during estate administration. The will, court documents and specific circumstances control the details, so confirm authority with the estate attorney before signing a listing agreement.

Should the date-of-death value be high or low?

Neither. It should be accurate and supportable. A credible fair market value gives the estate and heirs a documented basis for the eventual tax calculation. An Indiana licensed appraiser or a detailed market analysis may be appropriate depending on the circumstances and what your CPA recommends.
