You or your spouse has a Utah driver's license. We decided to live full time in a motorhome.Sold our house in Taylorsville and are traveling for our golden years. This guide will walk you through the key steps to sever ties with Utah, establish a new domicile, and manage any ongoing obligations like Utahsourced income. First you will need to have an official address (more on that later). Once that is done, you can apply for residency of the state your mailbox is located in. All income received during the period of residency is taxable in Utah, regardless of where that income is earned, unless specifically exempted. Are you a digital nomad looking for cool places to stay? A domicile is where you maintain your permanent legal address. It's also located in the state in which you pay your taxes.
