Entrepreneurs in Glendale, AZ: taxes and retirement for 2026

For solo founders and small-business owners in Glendale, AZ. Arizona has a flat 2.5% state income tax for 2026. Here are the 2026 rules, a worked example and the official sources.

What's different in Glendale

Local income tax: No city income tax in Glendale.
Glendale city transaction privilege (sales) tax: Businesses doing taxable activities in Glendale pay city TPT on top of state and county TPT: 2.9% for retail, contracting, transporting, amusements, advertising, and rentals, and 3.9% for restaurants and bars (ADOR rate table effective Oct. 1, 2026). It is filed through an Arizona TPT license.
City business license: Yes. All home occupations (home-based businesses) must get and keep a Glendale Business License, which costs $25 initially and $25 per year to renew. Some home businesses may also need a Conditional Use Permit.
Also worth knowing: Arizona cities do not levy personal income tax. Businesses subject to TPT need an Arizona TPT license in addition to the Glendale business license. Construction contractors based outside Glendale do not need a Glendale business license. We found no Glendale ordinance for gig, app-based, or freelance workers. No official state list of jurisdictions without a local income tax exists; this is confirmed via Tax Foundation's 2023 local income tax primer (secondary source, https://files.taxfoundation.org/20230222173518/Local-Income-Taxes-A-Primer-2023.pdf), which does not list this state among the 16 states whose localities levy income taxes, and we found no 2026 change.

Arizona rules for entrepreneurs

State income tax (2026): Arizona has a flat 2.5% state income tax for 2026. The 2026 Form 140ES worksheet figures estimated tax at 2.5% of Arizona taxable income. Arizona also lets taxpayers elect to report small business income separately on Form 140-SBI.
State estimated tax: You must make 2026 Arizona estimated payments if your Arizona gross income was over $75,000 in 2025 and is over $75,000 in 2026 ($150,000 for both years if married filing jointly). Same dates as federal: April 15, June 15, and September 15, 2026, and January 15, 2027. Form 140ES.
Arizona transaction privilege tax (TPT): TPT is a tax on the vendor for the privilege of doing business in Arizona. A sole proprietor in a taxable classification, such as retail sales, restaurants and bars, contracting, or rentals, needs a state TPT license ($12 per location) and often a city license too. The state rate is 5.6%, plus county and city rates (ADOR TPT rate table, October 2026).
Declaration of Independent Business Status (A.R.S. 23-1601): An optional signed declaration in which the contractor affirms they run their own business and are responsible for their own taxes and licenses. It must also show at least six of ten listed independence factors. When the parties act consistently with it, the declaration creates a rebuttable presumption that the worker is an independent contractor.
Qualified marketplace contractors (A.R.S. 23-1603): Workers who find jobs through a qualified marketplace platform are independent contractors for all state and local law purposes, including unemployment and workers' compensation, if three conditions are met: they are paid for output, they have a written contract, and they keep control over their hours and their freedom to work elsewhere. Sealed freight and parcel delivery is excluded.

Federal rules for 2026

Entity choice changes your taxes

A single-member LLC is taxed like a sole proprietorship unless it elects S-corp status. The S-corp can lower payroll tax but adds payroll, a separate return and a reasonable-salary requirement.

Retirement as a tax lever

With no employees, a Solo 401(k) allows up to $72,000 in 2026. With employees, a SEP IRA or a 401(k) must generally cover eligible staff too.

Quarterly estimated taxes

No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.

Self-employment tax

On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.

A worked example

A solo founder with $200,000 of profit in 2026
Self-employment tax as a sole proprietor	$28,234
Solo 401(k) maximum as a sole proprietor	$61,677
Payroll tax saved as an S-corp on a $100,000 salary	$12,934
Solo 401(k) maximum as that S-corp	$49,500

Federal figures only. S-corps add running costs (payroll, an 1120-S return, state fees) not shown here. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
