Taxes for new residents of Utah.

Utah taxes fall into a few buckets, and none of them is complicated once you see the whole picture. Your income gets taxed at a single flat state rate, which is 4.45 percent of taxable income for 2026, and there is no city or county income tax on top of it, so where you live inside Utah does not change your income tax bill. Your home gets taxed by the county, and Utah gives your primary residence a real break: it is taxed on 55 percent of its market value, while a second home or rental is taxed on the full value. What you buy gets a sales tax that starts at a state-imposed 4.85 percent and rises with local add-ons, so the combined rate is a little different in St. George than in Park City. And a few things simply have to get done after you arrive, chiefly registering your vehicle within 60 days and moving your driver license over.

The other piece people ask about is when Utah starts counting you as a resident for tax purposes. The short version is that you become a Utah resident either by making Utah your domicile, meaning your permanent home base, or by spending 183 or more days here in a tax year. Move partway through the year and you usually file a part-year return, paying Utah tax on income earned once you became a resident. That is the map. The rest of this page fills in each tax, tells you the exact deadlines, and flags the situations where you should stop reading a website and call a CPA.

Utah does not use brackets. It taxes every dollar of taxable income at the same flat rate, which for tax year 2026 is 4.45 percent. The Utah Legislature lowered it from 4.5 percent in the 2026 session under Senate Bill 60, part of a run of income tax cuts over the last several years, so if you are reading this later, check tax.utah.gov for the current-year figure rather than trusting a number you saw once. Just as important for a new resident: Utah has no local income tax. No city, county, or school district in the state levies its own income tax, so unlike some states you are leaving, your paycheck is not taxed differently in Salt Lake City than it is in Cedar City. Utah also applies a taxpayer tax credit that phases out at higher incomes and functions a bit like a standard deduction, which is one reason your effective rate can land below the headline 4.45 percent.

Florida, and it is worth modeling against the rest of the picture, because Utah housing and property tax often run lower than the high-tax coastal states people also move from. Retirement income deserves its own note. Utah does tax Social Security benefits and other retirement income, but it offers a Social Security Benefits Credit that can erase the tax entirely for lower and middle incomes and phases down above published thresholds, which as of mid-2026 begin around 54,000 dollars for a single filer and 90,000 dollars for a married couple filing jointly. There is also a separate retirement credit for certain taxpayers, and you cannot claim both in the same year. The interaction of these credits with your specific income is exactly the kind of thing to hand to a CPA. I can help you understand the housing math; a tax professional should run your actual numbers before you count on any credit.

One more practical point on becoming a filer here. You establish Utah residency for income tax either by domicile, which is the state you treat as your true, fixed, permanent home, or by keeping a place to live in Utah and spending 183 or more days here during the tax year. Domicile is fact-specific, and things like where you register to vote, where your driver license is issued, and where your vehicles are registered all feed into it, which is one reason the residency chores below are not just bureaucratic box-checking. They also help establish, cleanly, that Utah is now your home.

The part-year move is the most common wrinkle. If you land in Utah in, say, June, you were a nonresident for part of the year and a resident for the rest, and Utah generally has you file a part-year resident return that taxes the income you earned once you became a resident, plus any Utah-source income from before. Your former state has its own rules for the months you lived there, and the two returns have to agree on where each dollar belongs. This is squarely a CPA question, especially in the year of the move, because the split is where mistakes and double-taxation worries come from.

The remote worker is the second big one. If you move to Utah but keep a job with an employer based in another state, your wages generally become Utah income once you are a Utah resident working from Utah soil, and your old state may need to stop withholding. Some states are aggressive about taxing remote workers tied to an in-state employer, and a few have unusual rules, so if you are working remotely across a state line, do not guess. Get the withholding fixed early with your employer and confirm the treatment with a CPA, because getting it wrong quietly all year is a painful thing to unwind at filing time.

The last scenario is buying a second home or an investment property first, before it becomes your primary residence, which is common for people who buy in Utah while still living elsewhere. Until you actually make it your primary residence and claim the exemption, that property is taxed on 100 percent of its value, not 55 percent, and the income tax residency question turns on your domicile, not on owning Utah real estate. Plenty of people own a place in St. George for a year or two before they move for good. That is fine, it just means the property tax bill and the residency clock are on different tracks until you move in and make it official. Every one of these situations rewards a short conversation with a tax professional over a guess from a website, mine included.
