Choosing between an S-Corporation and an LLC is one of the most important decisions for Arizona small business owners. The right structure can reduce your tax bill, while the wrong one can cost you thousands each year.
Key Differences at a Glance
- LLC – Flexible and simple. By default, taxed as a sole proprietorship or partnership.
- S-Corp – More formal structure that can reduce self-employment taxes.
Self-Employment Tax Savings
This is usually the biggest reason business owners choose an S-Corp. With an LLC, all net profit is subject to self-employment tax (15.3%). With an S-Corp, only the salary you pay yourself is subject to payroll taxes. The remaining profit can be taken as distributions and is not subject to self-employment tax.
Arizona-Specific Considerations
- Arizona conforms to federal S-Corp taxation in most cases.
- Arizona does not have a state-level franchise tax on S-Corps like some other states.
- Payroll and unemployment tax rules still apply if you take a salary.
When an S-Corp Usually Makes Sense
- Your business consistently earns $60,000+ in net profit
- You are comfortable with extra formalities (payroll, reasonable salary, annual filings)
- You want to reduce self-employment tax
When an LLC May Be Better
- You are just starting out or have lower profits
- You prefer simpler bookkeeping and fewer formalities
- You may want to convert to an S-Corp later
