Utah Sales Tax Calculator (State & Local Rates)

What does a $1,000 purchase actually cost after tax in Utah? The answer starts with the state's 6.10% rate, but it does not end there. Local jurisdictions (cities, counties, and in some cases special taxing districts) are free to add their own surcharges on top of that, and the statewide average of those add-ons is 1.32%, which brings the typical combined rate to 7.42%.

That leaves Utah a bit below the roughly 7.3% average combined rate seen across the states that levy a general sales tax. That gap between the advertised price and the out-the-door total is exactly what this calculator is built to make transparent, using Utah's statewide average combined rate of 7.42%. Budgeting for a big-ticket purchase (a vehicle, an appliance, a piece of furniture) without accounting for that gap is one of the more common ways shoppers in Utah underestimate what they will actually owe at checkout.

Utah's 6.10% state figure is not purely a state rate. It bundles the statewide local increments that every Utah jurisdiction levies, including the local sales and use tax and the county option, which is why Utah's state rate looks high relative to its reputation as a low-tax state. On top of that, optional county and transit taxes average a further 1.32%, giving a combined 7.42% and $74.20 on a $1,000 purchase. Utah also taxes groceries at a reduced combined rate rather than exempting them.

All of the mandatory and optional layers apply to the same base and reduce to one rate:

The calculator performs:

1. Take the entered amount as the base. No adjustments are made to the price before tax is computed.
2. No item-level exemption filtering. The reduced grocery rate is not applied. Note also that the state portion reported below includes the statewide local increments bundled into the 6.10% figure.
3. Compute the state portion. The base is multiplied by the state statutory rate.
4. Apply the optional local surcharge. The 1.32% average covers county option, transit and resort community taxes adopted beyond the statewide baseline.
5. Sum and total. The state and local amounts are added to give total tax, and the total is added back to the price to give the out-of-pocket cost.

For a $1,000 taxable purchase in Utah:

1. Starting purchase price. The buyer rings up a $1,000.00 taxable retail purchase in Utah, the baseline amount before any tax is applied.
2. State portion. Utah's statutory state sales tax rate of 6.10% applies to the full purchase amount: $1,000.00 × 6.10% = $61.00 owed to the state.
3. Local portion. Local municipal, county, and special-district surcharges add an average of 1.32% on top of that: $1,000.00 × 1.32% = $13.20 more.
4. Combined tax due. Summing the two pieces, $61.00 in state tax plus $13.20 in local surcharge comes to $74.20 in total sales tax owed on the transaction.
5. Total out-of-pocket cost. Adding that $74.20 in tax to the $1,000.00 purchase price brings the buyer's total out-of-pocket cost to $1,074.20.

This example uses Utah's statewide average local rate of 1.32%; actual combined rates vary by city and county, so a real receipt could show a combined rate above or below the 7.42% average used here.

The per-$100 figure. A $100 taxable purchase in Utah carries $7.42 of combined tax. That is the whole marginal story on this page: the engine multiplies one base by one combined rate, so tax scales exactly linearly and the figure for any amount is $7.42 for every hundred dollars of it. At $1,000 it is $74.20; at $30,000 it is $2,226.00, which is thirty times $7.42 to the cent.

The state share against the local share. On the $1,000 default the split is $61.00 to the state at 6.10% and $13.20 to local jurisdictions at the 1.32% statewide average, so the local layer is 17.8% of the total tax collected. Turn the local surcharge off and the tax falls from $74.20 to $61.00, a difference of $13.20. On a $30,000 vehicle the same toggle moves the bill from $2,226.00 to $1,830.00, a difference of $396.00, which is the practical size of the question "which county did this sale happen in".

The reverse question, and the error it usually attracts. Someone holding a Utah receipt for $1,074.20 and wanting the pre-tax base cannot subtract the combined rate from it. Feed $1,074.20 back into this calculator as the purchase amount and it returns $79.71 of tax, because $1,074.20 is not the base: it already contains the tax. Deducting that $79.71 leaves $994.49, when the true base is $1,000.00. The error is $5.51 on a single $1,000 purchase, and it scales: on the $32,226.00 total of a $30,000 purchase the same wrong step returns $2,391.17 of tax and a base of $29,834.83, understating by $165.17.

The correct operation. Divide the tax-inclusive total by 1 plus the combined rate, or equivalently multiply it by the 7.42% fraction of the gross rather than of the base. The calculator adds tax to a base and does not run that direction: there is no tax-inclusive input on this page, and every figure it reports assumes the amount entered is exclusive of tax. Entering a till total instead of a net price overstates the tax by $5.51 per $1,000 every time.

• There is no tax-inclusive mode. The amount entered is treated as the pre-tax base without exception, so a total that already contains tax returns $79.71 rather than $74.20 on the $1,000 example.
• The local figure is a single statewide average, not an address lookup. The engine holds one 1.32% number for the whole state and applies it or does not; no county, city or special district rate exists anywhere in the code path.
• No item is exempt. The combined rate is applied to the whole amount entered, so groceries, prescriptions and any other statutory exemption have to be excluded from the input before it is entered.
• Statutory exemptions on unprepared groceries, prescription medications, or manufacturing equipment.
• Special industry excise taxes (lodging hotel taxes, vehicle rental fees, alcohol/tobacco excise).
• Use tax compliance on out-of-state untaxed online purchases.
• B2B resale certificate exemptions or direct pay permit programs.

• Confusing State and Combined Rates: Quoting the state base rate without factoring in local city and county add-on taxes.
• Overlooking Consumer Use Tax: Failing to self-report and remit use tax on untaxed out-of-state purchases on your state income tax return.
• Missing Annual Sales Tax Holidays: Many states offer annual tax-free weekends for back-to-school items, severe weather supplies, or energy-efficient appliances.
• Failing to Collect Resale Certificates: Selling wholesale without collecting valid exemption certificates exposes sellers to full sales tax liability upon audit.
