What taxes apply to a new small business?

Taxes Applicable to a New Small Business in Arizona

When starting a small business in Arizona, understanding your tax obligations is essential for smooth operations and compliance. Here are the primary taxes you should consider:

• Transaction Privilege Tax (TPT): Often referred to as a sales tax, Arizona’s TPT is a tax on the privilege of doing business. Most businesses must register for TPT and collect it on taxable sales. Rates vary by city and business activity.
• Income Tax: Arizona imposes a state income tax on business profits. Depending on your business structure (e.g., sole proprietorship, LLC, corporation), income tax filing and payment requirements differ. Ensure accurate bookkeeping to track taxable income.
• Withholding Tax: If you have employees, you must register for Arizona withholding tax. This involves withholding state income tax from employee wages and remitting it to the Arizona Department of Revenue.
• Unemployment Insurance Tax: Businesses with employees are required to pay unemployment insurance taxes to the Arizona Department of Economic Security. This supports unemployment benefits for eligible workers.
• Property Tax: If your business owns real or personal property, you may be subject to property taxes assessed by local counties. Maintain accurate records for property valuation and timely payments.
