Taxes in Tucson
Arizona charges a flat 2.5% individual income tax as of 2026 -- a real, structural difference from no-income-tax Sun Belt peers like Texas and Florida covered elsewhere in this project -- alongside a combined sales tax (Transaction Privilege Tax) in Tucson cited around 8.7% by one source, though Pima County's own public library page describes a wider 6.1%-8.7% range depending on the specific address and any special taxing districts.

Learn moreArizona's Flat 2.5% Income Tax: Real, Current, and Among the Lowest Flat Rates Nationally
Arizona converted from a graduated multi-bracket income tax system to a flat 2.5% rate starting with tax year 2023, and the Tax Foundation and multiple 2026 tax-preparation aggregators confirm this rate remains unchanged for the 2026 tax year -- among the lowest flat state income tax rates in the country. This applies uniformly to single filers, married couples filing jointly or separately, and heads of household. This is a genuinely different picture from the no-income-tax framing that applies to some other Sun Belt states covered elsewhere in this project -- Arizona residents, including Tucson residents, do pay state tax on wages and most other taxable income.
Tucson's Combined Sales Tax (TPT) Rate: A Real, Address-Dependent Figure
Arizona uses a Transaction Privilege Tax (TPT) rather than a traditional sales tax, technically levied on the seller rather than the buyer, though the cost is passed through to consumers in essentially the same way. Avalara cited a combined minimum rate of 8.7% for Tucson, breaking down to a 5.6% state rate, a 0.5% Pima County rate, and a 2.6% City of Tucson rate. Pima County Public Library's own page, however, describes a wider 6.1%-8.7% range that can apply depending on the specific ZIP code and any special taxing districts layered on top -- both figures are disclosed rather than collapsed into one number.
No State Estate Tax, No Real Estate Transfer Tax
Arizona does not impose a state estate tax on estates of people dying today, and it charges no state real estate transfer tax -- two genuine, if secondary, tax advantages for Arizona residents and property owners relative to states that impose either.
Social Security Is Fully Exempt; Other Retirement Income Is Mostly Taxable at the Flat Rate
Arizona allows a full subtraction for Social Security income under Title II of the Social Security Act -- no phase-out, no partial-taxation threshold, and no age requirement to qualify. Traditional IRA and 401(k) withdrawals, however, are generally taxable when included in federal adjusted gross income, at the same flat 2.5% rate as other income; up to $2,500 of qualifying federal, Arizona state, or Arizona local government pension income may be subtracted, and Arizona exempts military retirement pay specifically. See the retiring topic page for the fuller picture.
Property Taxes (Summary -- See Full Topic Page)
Property tax is the more disputed tax category for a Tucson homeowner specifically -- effective rates were cited anywhere from 0.78% to 0.85% across sources this session, with real, sourced ZIP-code-level variance layered on top (85735 at a cited 1.14% versus 85714 at 0.60%). See the property-taxes topic page for the full breakdown; this summary intentionally does not repeat that detail.
