Comparison
LLC vs S-Corp
Quick answer
An LLC is a legal structure; an S-Corp is a tax election. This is the most common source of confusion — an LLC can be taxed as an S-Corp. The real comparison is between an LLC taxed as a disregarded entity (paying full self-employment taxes on profits) versus an LLC or corporation that has elected S-Corp tax treatment (splitting income between salary and distributions to reduce SE tax).

Key differences
When to choose LLC (Default Taxation)
- Your net profit is below the threshold where S-Corp savings exceed payroll costs and accounting fees
- You want maximum simplicity — no payroll, no quarterly deposits, no 1120-S filing
- You anticipate bringing on international investors or complex ownership structures
- You are early-stage and prioritizing cash conservation over tax optimization
When to choose S-Corp Election
- Your net profit consistently exceeds $50,000–$80,000 and SE tax savings would exceed the added cost
- You want to split income between W-2 salary and distributions to reduce your self-employment tax
- You have an established business with predictable income and can commit to running payroll
- Your tax advisor has modeled the after-tax savings and confirmed they justify the complexity
Which Should You Choose?
The LLC vs. S-Corp decision is really a tax optimization question — and the answer depends on your specific income level, state, and business structure. Most business owners should model both scenarios with a tax advisor before making the election. Switching to S-Corp too early adds compliance costs that can exceed the savings; switching too late leaves real money on the table.
Typical cost
Consultation
₩20,000–₩150,000 per session
Online platforms are at the low end and traditional offices at the high end. Many offices credit the fee against later filing work.
Capital gains tax return (양도소득세)
₩150,000–₩800,000 per return
Reported market range for a standard sale of a home or land. Several properties or incomplete purchase records cost more.
Gift tax return (증여세)
from ₩500,000
Usually a minimum fee per case, with a small percentage of the gifted amount added for larger gifts.
Inheritance tax return (상속세)
from ₩700,000
A minimum fee per case. It scales with the value and number of assets, and complex estates cost far more.
Tax audit response (세무조사 대응)
₩3,000,000–₩7,000,000
Reported range for a mid-size company. Often a retainer plus a success fee, so get the terms in writing.
