Utah vs Nevada Taxes for Retirees: St. George vs Mesquite in 2026

A retired couple living in St. George, Utah on $36,000 of Social Security and $30,000 of pension income pays $0 in Utah income tax for 2026, and I ran that through my own income tax calculator this morning at Utah's new 4.45% rate. Mesquite, Nevada, 40 minutes down the freeway, charges no income tax at all, which is the line every Nevada brochure leads with. What the brochure skips is the house: on a $500,000 primary home, the property tax runs about $1,814 a year in St. George and up to $4,854 in Mesquite at its fiscal 2026-27 rate. So the real answer to "which state is cheaper for retirees" depends on how your income is split between Social Security and everything else, and on the house you buy. I ran nine retiree profiles through both calculators so you can see exactly where Nevada wins and where it does not.

Is Nevada really cheaper than Utah for retirees?

Not for most of the retiree profiles I ran, and the reason is property tax. Nevada has no personal income tax, and Article 10, Section 1 of the Nevada Constitution says one cannot be levied on the wages or personal income of natural persons. Utah charges a flat 4.45% for tax year 2026 under SB 60, passed in the 2026 General Session and applied back to January 1. But Utah's Social Security credit and taxpayer credit erase much or all of that for moderate retirement incomes, while Mesquite's property tax rate of $2.7737 per $100 of assessed value lands far harder on a newer home than St. George's does.

The crossover is real, though, and I want to be plain about it. A couple with $130,000 or more of mostly pension and IRA income will usually come out ahead in Nevada, and anyone buying an older Mesquite home with a low taxable value comes out ahead at lower incomes than that. The sections below show the math for each case.

What does a retired couple actually pay in Utah income tax in 2026?

A married couple with income under $90,000 that leans on Social Security often pays nothing, and a couple at the same total income that leans on a pension can pay $1,500 or more. Every figure in the table below comes from my Southern Utah income tax calculator, run on November 2, 2026 with both spouses aged 65 to 73. The calculator uses the 4.45% rate from SB 60, the Social Security credit thresholds from Utah Code 59-10-1042, and the 2025 TC-40 instructions from the Utah State Tax Commission for the worksheet mechanics.

Look at the two $85,000 couples. Same total income, same filing status, same ages, and one pays $294 while the other pays $1,587. That $1,293 gap is entirely about the mix. The military retiree couple is the other surprise: their Utah tax before credits came to $2,577, and a $1,780 military retirement credit, stacked on the taxpayer and Social Security credits, took it to zero. You can run your own mix the same way I did.

Open the Southern Utah income tax calculator.

Why does the income mix matter more than the total?

Because Utah's Social Security credit only covers the Social Security part of your income. Utah starts from your federal adjusted gross income, which includes whatever share of your benefits the IRS counts as taxable, and taxes it at 4.45%. Then the Social Security credit gives back 4.45% of the benefits that were included, so for a couple under the threshold the tax on Social Security nets to zero. Pension, IRA and 401(k) withdrawals get no such credit. They are taxed at the flat rate, less whatever is left of the general taxpayer tax credit, which shrinks as income rises.

The phase-out is the part most national comparison sites get wrong. Under Utah Code 59-10-1042, the Social Security credit drops by 2.5 cents for every dollar of income over $90,000 for married couples filing jointly and over $54,000 for single filers. The $96,000 couple in the table owes $15 of tax on their Social Security, the $130,000 couple owes $813, and the $150,000 couple owes $1,350. Below those thresholds it is zero. I still see national sites quoting Utah at 4.5% or 4.55%, which were the 2025 and 2024 rates. The 2026 rate is 4.45%, and that rate cut also trims the Social Security credit percentage, because the credit is tied to the rate.

One more trap if you read the Tax Commission's own site. Its stand-alone Social Security credit page was still showing an older worksheet with $30,000 and $50,000 thresholds when it was checked on November 2, 2026, while the statute and the TC-40 instructions use $54,000 and $90,000. Go by the statute and the TC-40 instructions.

How much higher is property tax in Mesquite than in St. George?

On a newly built primary home, Mesquite's bill can run up to about 2.7 times St. George's. Utah taxes a primary residence on only 55% of its market value, because Utah Code 59-2-103 exempts 45%, and the St. George figures below use the 2026 proposed rate for the St. George tax area. Nevada assesses at 35% of taxable value under NRS 361.225, and every one of Mesquite's three tax districts, 901, 902 and 903, carries the same fiscal 2026-27 rate of $2.7737 per $100, per the Nevada Legislative Counsel Bureau's summary of the Department of Taxation's rate book.

The Mesquite column is a ceiling, and I label it that way on purpose. Nevada's taxable value is not the sale price. It is land at market value plus the replacement cost of the house, depreciated 1.5% a year under NRS 361.227, so an older Mesquite home typically pays less than the table shows. For an exact figure on a specific Mesquite house, pull its taxable value from the Clark County Assessor before you compare. I could not verify a typical older-home figure that would hold across the city, so I am not going to guess one.

Nevada also caps how fast an owner's bill can grow. Under NRS 361.4723, the tax bill on an owner-occupied single-family primary residence cannot rise more than 3% a year, and the Nevada Department of Taxation's final cap factors for fiscal 2026-27 set the cap on other property in Clark County, rentals and second homes included, at 8%. Utah has no percentage cap like that on a homeowner's bill. That is a real point in Mesquite's favor for someone planning to stay twenty years.

The property tax calculator shows these cities side by side, along with Hurricane, Ivins, Washington City and the rest of the county.

So which retirees does Nevada actually win?

Nevada wins when your Utah income tax is bigger than the property tax gap on the house you would buy. On a new $500,000 home, that gap is up to $3,040 a year in St. George's favor. Seven of the nine profiles above pay less than that in Utah income tax, so they come out ahead in St. George on these two taxes. The $130,000 couple pays $3,361 in Utah, which puts Nevada ahead by about $321 a year even against a brand new Mesquite home. The $150,000 couple pays $5,513, so Nevada wins by about $2,473 before you even look at the house's age.

Two things move the line. Buy a more expensive house and the property tax gap grows, which pushes the crossover toward higher incomes; at $800,000 the gap is up to $4,864. Buy an older Mesquite home with a lower taxable value and the gap shrinks, which pulls the crossover down toward the $85,000 pension-heavy couple. A second home flips part of the math too, because Utah's 45% exemption applies only to a primary residence. A $600,000 second home in St. George runs about $3,958 a year in the calculator, against the same $5,825 ceiling in Mesquite.

The Nevada pitch almost always stops at the income tax number. Put real Social Security and pension figures into both calculators and the answer is usually closer than people expect, and for Social Security-heavy households it runs the other way, as the table shows.

Is sales tax lower in St. George or Mesquite?

St. George is lower on most purchases, and Mesquite is lower on groceries. The Utah State Tax Commission's combined rate table, in effect October 1, 2026, puts the city of St. George at 6.75%. The Nevada Department of Taxation's rate components table puts Clark County, which includes Mesquite, at 8.375%. On every $10,000 of taxable purchases like furniture, appliances or a golf cart, that is $162.50 more in Mesquite.

Groceries go the other way. Utah taxes food and food ingredients at 3.0% statewide, while Article 10, Section 3A of the Nevada Constitution exempts food for human consumption, other than prepared food and alcohol. Every $10,000 of groceries costs about $300 more in tax in St. George. Inside Washington County, rates are not uniform either: Washington City added a 0.33% emergency services tax on October 1, 2026, which took it to 7.08%, the same rate Hurricane already charges, while Ivins and Santa Clara match St. George at 6.75%.

What else should retirees compare besides income and property tax?

Vehicle fees are worth a look if you keep newer cars. Utah charges an age-based uniform fee in place of property tax on passenger vehicles under Utah Code 59-2-405.1, running from $150 a year for a vehicle under three years old down to $10 at twelve years and older. Nevada charges a Governmental Services Tax of 4 cents per dollar of depreciated value, plus a 1 cent supplemental tax in Clark County, and the Nevada DMV's own worked example for a two-year-old car with a $20,000 MSRP comes to $298 before the registration fee.

Estate and inheritance taxes are a wash. Neither state has one. The Utah State Tax Commission says Utah's estate tax ended after December 31, 2004, and the Nevada Constitution bans an inheritance tax outright. Your heirs face only the federal estate tax in either place.

Closing costs differ too, and those hit once rather than every year. My closing cost calculator covers the Utah side using First American Title's published Utah rates. If you are still deciding between St. George, Hurricane and Ivins rather than between two states, I compared those three towns for retirees in an earlier post.

How to run your own numbers in ten minutes

Start with the income tax calculator, enter your real Social Security and pension or IRA figures, and note the Utah total. Then open the property tax calculator, set the price you expect to pay, and read the St. George and Mesquite lines. Subtract one from the other and compare it to your Utah income tax. If the property tax gap is bigger, St. George is cheaper on these two taxes; if your Utah income tax is bigger, Nevada is. Then adjust the Mesquite figure down if you are looking at an older home there.

Frequently asked questions

Does Utah tax Social Security in 2026?

Yes, but most retired couples under $90,000 of income end up paying nothing on it. Utah taxes the federally taxable part of your benefits at 4.45%, then gives back a Social Security credit at the same rate. Under Utah Code 59-10-1042 that credit shrinks by 2.5 cents for each dollar of income over $90,000 for married couples and $54,000 for single filers.

How much Utah income tax would a retired couple making $66,000 pay?

$0, if the $66,000 is $36,000 of Social Security and $30,000 of pension, per my income tax calculator at the 2026 rate of 4.45%. Shift the same total toward pension income and a tax bill appears, because the Social Security credit covers only the Social Security part.

Is property tax higher in Mesquite, Nevada than in St. George, Utah?

Yes, on a newly built primary home it can run up to about 2.7 times higher. A $500,000 primary home comes to about $1,814 a year in St. George and up to $4,854 in Mesquite at the fiscal 2026-27 rate of $2.7737 per $100 of assessed value. Older Mesquite homes usually pay less, because Nevada depreciates the building in its taxable value.

Does Nevada cap property tax increases?

Yes. Under NRS 361.4723, the yearly increase in the tax bill on an owner-occupied single-family primary residence is capped at 3%. For other property in Clark County, including rentals and second homes, the Nevada Department of Taxation set the fiscal 2026-27 cap at 8%. Utah has no comparable percentage cap on a homeowner's bill.

Is sales tax lower in St. George or Mesquite?

St. George is lower on most purchases, at 6.75% against 8.375% in Clark County as of October 1, 2026. Groceries are the exception: Utah taxes food at 3.0% statewide, and Nevada exempts unprepared food entirely.

Does Utah or Nevada have an estate or inheritance tax?

No. Utah's estate tax ended after December 31, 2004, according to the Utah State Tax Commission, and the Nevada Constitution prohibits an inheritance tax. Only the federal estate tax applies in either state.
