Missouri state tax on a house sale in nevada

[Jinhua63]

I sold a rental property in Los vegas last November (2021). We I file missouri state tax, the Tubotax software includes my net income from the house sale into my 2021 total income so that my total income for 2021  which results in big missouri state tax for 2021. Because the rental property is in Los vegas, Nevada, could you tell me how to file the state tax for this house sale?

Unfortunately, as a Missouri state resident you must pay taxes on income, regardless of source, so you must include the Nevada sale.

I have further question. I will sell my property in California in 2022. And I need to pay the income tax of the house sale  in CA state although I live in Missouri. . If I pay the house sale income tax in missouri, I pay twice for the same house sale income , which is in fair to me. For the state tax. Could you tell me how to deal with this issue?
