Myself and brother and sister inherited our parent's home after they died, and we sold it in 2019. We owned the house approx 1 year and did not live there. Do we owe tax?

I'm so sorry for your loss.

Yes, you might owe some income taxes if the property increased in value from the date of your parent's passing to the date you sold it. 

• You would only pay income taxes on the amount of the increase. For example: If the property value was 100,000 on 1/2/18 and you sold it for $125,000 one year later, you would split the $25,000 gain between your siblings and pay taxes on 1/3 of the $25,000.
• If the property did not increase in value, you would enter the sale but your basis in the home would be equal to your sales proceeds.
• You would report the gain or loss from the sale as a capital gain or loss on Schedule D.
• Note: If the value of the property decreased in the year that you owned it, you would report the sale however you wouldn't be able to claim the loss since this is a personal loss. Personal losses are not deductible and TurboTax will give you a message that it's a personal loss and not deductible. 

To enter, see Where do I enter the sale of a second home, an inherited home, or land on my 2019 taxes?

Assuming that ownership was 1/3 to each sibling, then each sibling would enter the sale of an asset using 1/3 the cost basis or inherited value, and 1/3 the selling price.  

You can probably get an estimate of the market price of the home on the date of the previous owners death from a local real estate appraiser. They can do retroactive appraisals using historical data.
