As a cybersecurity LLC in Arizona, your tax structure depends on your elections. By default, a single-member LLC is treated as a disregarded entity for tax purposes, meaning profits are passed through to the owner and taxed at the individual level. Multi-member LLCs are taxed as partnerships. Our resource on [how to register an LLC in Arizona](https://www.lovie.co/formation/resources/llc-formation/agency-arizona) breaks this down further. However, you can elect to be taxed as an S-Corp or C-Corp, each having different tax implications. Arizona has a flat individual income tax rate, but also the Transaction Privilege Tax (TPT) which is a sales tax.
