It appears this question refers to Alaska, but the provided content focuses on Arizona. However, in Arizona, sales tax filing due dates are consistent across the state, based on the business's assigned filing frequency rather than varying by municipality. Businesses in Arizona file their Transaction Privilege Tax (TPT) returns monthly, quarterly, or annually, depending on their gross sales volume. Here's how it works:

• Monthly Filing: Due by the 20th of the following month for businesses with higher sales volumes.

• Quarterly Filing: Due by the 20th after the end of each quarter for moderate sales volumes.

• Annual Filing: Due by January 20th of the following year for businesses with lower sales volumes.

Businesses must adhere to their specific filing schedule to ensure timely compliance and avoid penalties. Arizona’s online filing system through ADOR streamlines the process, allowing businesses to manage their filings efficiently regardless of location within the state.
