When an LLC Makes More Sense

- You plan to have foreign investors or multiple entity types as owners
When an S-Corp Makes More Sense

- You want to minimize self-employment taxes on distributions
- You're comfortable with corporate formalities and payroll requirements
- You plan to reinvest profits in the business rather than distribute everything
Tax Deep Dive
Llc Default Tax
Idaho LLCs are taxed as pass-through entities by default, meaning all business profits flow through to your personal tax return and are subject to both income tax and 15.3% self-employment tax. Single-member LLCs file Schedule C, while multi-member LLCs file Form 1065.
S Corp Tax
S-Corps split owner compensation into salary (subject to payroll taxes) and distributions (not subject to self-employment tax). Owners must pay themselves a reasonable salary for services performed, but additional profits can be distributed without the 15.3% self-employment tax burden.
Breakeven Income
In Idaho, S-Corp election typically becomes beneficial when business profits exceed $60,000-70,000 annually, as the payroll tax savings on distributions outweigh the additional compliance costs and complexity.
