FAQ
When should a Arizona LLC elect S-Corp taxation?
When net profit consistently exceeds $80K-$100K per active owner. Below that, the ~$2,000-$4,000/yr compliance cost (payroll + 1120-S filing + CPA) exceeds the SE tax savings. At $150K profit, expect $5K-$10K net savings. At $250K+, savings scale to $15K+/yr.
How much SE tax does S-Corp election save in Arizona?
Example: $150K profit. Default LLC pays 15.3% SE tax on ~$140K net = $21,420. S-Corp with $60K W-2 salary: 15.3% on $60K = $9,180. Remaining $90K taken as distributions (no SE tax). Gross savings: $12,240. After $3K compliance costs: $9,240 net savings.
Can I elect S-Corp without changing my Arizona LLC entity?
Yes. File IRS Form 2553 — your LLC stays an LLC legally but is taxed as an S-Corporation federally. Arizona state tax generally follows federal classification (with some exceptions like CA's 1.5% S-Corp entity tax).
What's "reasonable compensation" for an S-Corp owner in Arizona?
The W-2 salary you pay yourself must be reasonable for the services rendered. Rule of thumb: 30-60% of total profit for service businesses. Use our [Reasonable Compensation Calculator](/tools/reasonable-compensation) for industry-specific benchmarks adjusted for Arizona cost of labor.
What are the downsides of S-Corp election in Arizona?
Added complexity: (1) Must run payroll monthly ($40-$100/mo for Gusto/Rippling). (2) Must file Form 1120-S annually ($1,500-$3,000 CPA). (3) Must pay reasonable compensation even in lean months. (4) Some Arizona-specific entity taxes may apply (CA 1.5%, IL 1.5%, TN 6.5% excise).
What's the Form 2553 deadline for S-Corp election?
Within 2 months and 15 days of the target effective date. For calendar-year LLCs wanting Jan 1 effective date: March 15. For new LLCs: within 2m 15d of formation. Late election relief via Rev. Proc. 2013-30 allows retroactive elections up to 3 years past intended date.
