The Gilbert, Arizona sales tax rate is 8.3% on most retail purchases, a figure that took effect January 1, 2025, after the town raised its municipal portion from 1.5% to 2.0%.1Gilbert, Arizona. Frequently Asked Questions What locals call sales tax is technically a Transaction Privilege Tax (TPT). The legal distinction is that the tax falls on the business for the privilege of operating in Gilbert rather than on the buyer. Vendors pass the cost through at the register, but if one fails to collect or remit, the liability stays with the vendor.
How the 8.3% Rate Breaks Down
Three layers of government each take a slice of every taxable sale in Gilbert:
- Arizona state: 5.6%
- Maricopa County: 0.7%
- Town of Gilbert: 2.0%
The Town Council passed Ordinance 2918 on October 22, 2024, raising Gilbert’s municipal rate from 1.5% to 2.0% starting January 1, 2025.2Arizona Department of Revenue. Gilbert Transaction Privilege Tax Rates That half-point increase moved the combined rate from 7.6% to 8.3%. The county’s 0.7% primarily funds regional transportation through Maricopa County’s transportation excise tax.
Gilbert follows the Model City Tax Code, the shared framework most Arizona cities and towns use to define what counts as a taxable activity.3Arizona Department of Revenue. Model City Tax Code Individual towns can still vary which items they tax or exempt, but the structure is largely consistent across the state.
What Gets Taxed and What Doesn’t
Retail sales of tangible goods carry the full 8.3%. The tax also reaches restaurants and bars, amusements such as movie theaters and sporting events, telecommunications, and construction contracting.2Arizona Department of Revenue. Gilbert Transaction Privilege Tax Rates
A few common purchases are exempt. Prescription drugs, insulin, prosthetics, prescription eyeglasses, and hearing aids are exempt at every level.4Arizona Legislature. Arizona Revised Statutes 42-5159 – Exemptions Groceries and unprepared food for home consumption are exempt from the state’s 5.6% portion, but Gilbert still charges its 2.0% municipal rate on them.2Arizona Department of Revenue. Gilbert Transaction Privilege Tax Rates Your receipt will show a lower tax on grocery items than on other retail goods.
Construction contracting works differently from a standard retail sale. Prime contractors pay TPT on 65% of gross project proceeds rather than the full contract price, because the base is designed to capture labor and overhead while excluding materials that were already taxed when purchased.5Arizona Legislature. Arizona Revised Statutes 42-5075 – Prime Contracting Classification; Exemptions; Definitions
Hotels and Short-Term Rentals
Lodging in Gilbert is taxed much more heavily than regular retail. A stay counts as transient if it lasts fewer than 30 consecutive days.6Arizona Legislature. Arizona Revised Statutes 42-5070 – Transient Lodging Classification; Definition For those stays, Gilbert charges its 2.0% TPT plus an additional 5.0% lodging surcharge, so the town’s portion alone comes to 7.0%. With the state and county added, the combined rate on a Gilbert hotel bill is 14.27%.7Gilbert, Arizona. Real Property Rentals
The lodging surcharge was raised from 2.8% to 5.0% in the same October 2024 ordinance that lifted the base rate. Anyone operating a short-term rental in Gilbert needs both a TPT license and a separate short-term rental license from the town.
Long-Term Residential Rentals Are No Longer Taxed
If you rent out a home or apartment in Gilbert on a long-term basis of 30 days or more, no Arizona city can collect TPT on that rental income anymore. The change took effect January 1, 2025, through an amendment to A.R.S. 42-6004(H) that prohibits municipalities statewide from levying TPT on qualifying residential rental income.8Arizona Department of Revenue. Residential Rental Tax Changes Coming in the New Year The repeal does not touch commercial property rentals or short-term rentals under 30 days, which stay fully taxable at the lodging rates above.
Buying from Out-of-State Sellers
When you buy something from an out-of-state seller who doesn’t charge Arizona tax, you owe use tax at the same combined rate. The state use tax is 5.6%, and Gilbert adds its 2.0% municipal use tax on top.9Arizona Department of Revenue. Understanding Use Tax This covers online purchases, catalog orders, and other out-of-state buys for use in Arizona where no equivalent tax was collected.
In practice, most large online retailers already collect Arizona TPT, so use tax tends to come up only with smaller out-of-state vendors. Casual sales between individuals are not subject to use tax. If you buy a vehicle from an out-of-state dealer, the Arizona Department of Transportation collects the use tax at registration if the seller didn’t charge an equivalent amount.
If You’re a Business Collecting the Tax
Any business conducting taxable activity in Gilbert needs a TPT license before it starts operating. You apply through the Arizona Joint Tax Application (Form JT-1), which registers you with the state and the town at the same time.10Arizona Department of Revenue. Joint Tax Application for a TPT License The application asks for your legal business name, EIN or Social Security Number, ownership structure, physical address, and estimated gross income. That estimate determines your filing frequency, and the address determines which municipal rate applies, so make sure both are exact.
Filing frequency depends on estimated annual TPT liability across all Arizona jurisdictions:
- Monthly: more than $8,000
- Quarterly: $2,000 to $8,000
- Annual: less than $2,000
Returns are due by the 20th of the month following the reporting period. Annual filers submit by January 20.11Arizona Department of Revenue. TPT Filing Frequency Most businesses file through AZTaxes.gov. Paper Form TPT-2 is only allowed if your prior-year liability was under $500 and you have a single location; otherwise electronic filing is mandatory.12Arizona Legislature. Arizona Revised Statutes 42-5014 – Return and Payment of Tax; Estimated Tax; Extensions
Late returns draw a filing penalty of 4.5% of the tax due per month (minimum $25), capped at 25% or $100. A separate late-payment penalty of 0.5% per month applies to the unpaid balance, capped at 10%. Combined penalties cannot exceed 25% of the tax due.13Arizona Department of Revenue. Transaction Privilege, Use, and Severance Tax Return Instructions Interest accrues on unpaid balances at the federal short-term rate plus three points, compounded annually.14Arizona Department of Revenue.
