Comparison
Tax Advisor vs Tax Preparer
Quick answer
A tax preparer takes your financial information and files your return based on what already happened. A tax advisor helps you make decisions throughout the year to reduce what you owe before those decisions are locked in. One is reactive; the other is proactive. For anyone with meaningful income or a business, both roles are valuable — but they solve different problems.

Key differences
When to choose Tax Advisor
- You want to reduce next year's tax bill before year-end decisions close your options
- You are starting or restructuring a business and want the optimal entity setup
- You have a major financial event coming — selling a business, exercising options, receiving inheritance
- You are self-employed and want to capture every legal deduction proactively
- You want quarterly check-ins to keep your tax position optimized throughout the year
When to choose Tax Preparer
- Your taxes are already decided and you need accurate, timely returns filed
- You have a straightforward W-2 or small business and need compliance without strategy
- You received a CP2000 notice or need an amended return filed
- You want to outsource the preparation work while managing strategy yourself
- Cost is a priority and you want a flat-fee filing service
Which Should You Choose?
If you're just filing what already happened, a tax preparer handles the job well. If you have meaningful income, a business, or financial complexity, a tax advisor pays for themselves in saved taxes — but only if you engage them before year-end, not after. The most effective approach is a tax advisor who can also prepare your returns.
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.
