LLC vs S-Corp: which is better for taxes?
LLC versus S-Corp is a common tax planning decision for small business owners. This guide explains the trade-offs, including self-employment tax, payroll requirements, and potential savings, plus calculators that estimate outcomes under each structure.
Key differences
- LLCs default to pass-through taxation with SE tax on profits.
- S-Corps can reduce SE tax by splitting salary and distributions.
When S-Corp savings appear
- Higher net income where owner wages can be reasonable.
- Ability to manage payroll and compliance costs.
What to consider before switching
- Additional payroll filing obligations.
- State-level S-Corp rules or fees.
Put this tax guide into practice
Identify the tax year, filing status, income type, and household or business facts that apply before comparing options. Keep the source documents behind each number and use the linked calculator for a repeatable estimate. Changing one assumption at a time makes it easier to see which rule drives the result.
Review the calculator's assumptions, caveats, update date, and primary source links before acting. A guide can explain the planning framework, but official forms and instructions control a filed return. Seek qualified advice for notices, amended returns, multiple jurisdictions, business entities, or material transactions.
Save the assumptions used with the estimate and revisit them after an official annual adjustment or a change in income, residency, household, employment, or investment plans. Consistent inputs make comparisons meaningful.
