Starting a business in Arizona?

Starting your business is exciting, but dealing with taxes can feel overwhelming. Don’t worry! This guide breaks down Arizona business taxes in a simple way so you can focus on growing your business while staying compliant.

 

Understanding Arizona business taxes

Arizona businesses are subject to several types of taxes, depending on your structure and activities. The most common ones include:

 

Transaction Privilege Tax (TPT): Often called sales tax, this applies to businesses selling goods and some services.

 

Corporate Income Tax: Applies to C corporations operating in Arizona.

 

Employer Withholding Tax: If you have employees, you must withhold state income taxes.

 

Unemployment Tax: Employers contribute to the state unemployment insurance program.

 

Who needs to pay what?

Your tax obligations depend on your business type. Sole proprietors, LLCs, partnerships, and corporations have different requirements. For example, LLCs may have pass-through taxation, while corporations file corporate income tax separately.

 

Registering for taxes

Before you start collecting taxes, register with the Arizona Department of Revenue (ADOR). You can apply for a TPT license online, making the process simple and fast.

 

Filing and paying taxes on time

Filing deadlines vary based on the tax type and your filing frequency. Late payments can lead to penalties, so set reminders or use accounting software to stay on track.

 

Tax deductions you shouldn’t miss

Did you know you can reduce your tax burden by claiming deductions? Expenses like office supplies, business travel, and even certain home office costs may qualify. Keep accurate records to maximize your savings.
