Salon Business Codes: Your Key to Lower Taxes in 2026

Will 5 Minutes Today Define Your Bank Account in 3 Years?

Hello! I'm Park Gyeong-a, but you can call me the 'Beauty Mentor Angel.' From my office here at Han-gang Posville, just outside exit 12 of Dangsan Station in Seoul, I've guided countless aspiring entrepreneurs through the entire A-to-Z process of launching a successful beauty shop. I know that feeling all too well—the initial thrill of finally opening your own place, quickly followed by the overwhelming dread of facing a mountain of paperwork called 'business registration.' It's a confusing maze of official documents and unfamiliar jargon that can make anyone feel lost.

Among all those terms, one thing seems deceptively simple: the 'business registration code,' known as an eopjong-codeu in Korea. It's just a few numbers, right? It's easy to dismiss it as a minor detail. But in reality, this little code is the master key that will determine your future tax bills, your eligibility for crucial government grants, and your capacity for growth. So, let me get straight to the point with no fluff, because this is the most important piece of advice I can give you today: Even if you only plan to open a nail salon, you absolutely must register both a taxable business code and a tax-exempt one. Specifically, list '930206 (Skincare Services/Taxable)' as your primary business type and '930205 (Other Beauty Services/Tax-exempt)' as your secondary type. This is the single most effective strategy to avoid a future tax bomb and seize opportunities for expansion that you haven't even thought of yet. With 25 years of experience in this industry, I'm going to pour all my knowledge into explaining exactly why this is non-negotiable.

What's the Core Strategy in a Nutshell?

- For maximum tax savings and future-proofing, register your business with 930206 (Skincare/Taxable) as your primary code and 930205 (Other Beauty Services/Tax-exempt) as your secondary code, even if you only plan to offer nail services initially.

- This dual-code structure allows you to legally separate your revenue, which helps you maintain the highly advantageous 'simplified taxpayer' status for a much longer period, significantly reducing your tax burden.

- Your business code directly determines whether a 10% Value-Added Tax (VAT) applies to each service, impacting your pricing strategy, competitiveness, and eligibility for things like government grants.

How Can One Business Code Cost You Government Funding? A True Story

Are you thinking to yourself, "But I'm only going to do nails, so the tax-exempt code (930205) is all I need"? That single, seemingly logical thought can be incredibly risky, and I want to share a real story from one of my own students to show you just how much can be at stake. Let's call her Ms. Choi. She was a wonderfully talented student at my 'Beauridge Lifelong Education Center.' In early 2025, she finally achieved her lifelong dream of opening a cozy, beautiful nail salon near the trendy Hongdae area of Seoul. Since nail art is a tax-exempt service in Korea, she logically registered only with the 930205 code. For the first few months, everything seemed perfect.

About six months after her grand opening, an announcement came out from the Korean Ministry of SMEs and Startups. It was for a 'Growth Promotion Fund' designed specifically to help small business owners like her. This wasn't just any loan; it offered incredibly low interest rates and a generous credit limit that was far better than any commercial bank could offer. For Ms. Choi, it was the golden opportunity she needed to upgrade her shop's equipment—to buy the premium chairs her clients deserved and the state-of-the-art ventilation system she needed—and take her business to the next level.

Ms. Choi told me she felt like the announcement was a sign from the universe. "This is my chance!" she thought. She stayed up all night, pouring her heart and soul into the business proposal. She meticulously researched and listed the exact model numbers of the latest LED gel lamps and advanced dust collectors she dreamed of buying for her salon. She painted a vivid picture of her vision for growth and submitted her application, filled with hope and excitement. The result? Her application was rejected at the initial document review stage. The reason given was devastatingly simple: 'Limited business scope.' The review committee evaluated her business, which was registered solely as a tax-exempt entity, as having low potential for future revenue growth. In their eyes, her business was a one-trick pony. Had she also registered the taxable business code for skincare (930206) from the very beginning, her application would have signaled a clear potential for diversification—the ability to add profitable services like waxing or eyelash extensions down the line. This would have demonstrated scalability, a key factor that government bodies look for, and it would have dramatically increased her chances of securing those funds. In fact, if you review the official 2026 startup support criteria from the Ministry of SMEs and Startups, 'potential for business expansion and diversification' is consistently listed as a key evaluation metric. Ms. Choi was beside herself with regret for not adding that one extra line of code to her business registration. You have to understand: this isn't just a bureaucratic chore. It's a critical investment in your future.

How Do Nail and Skincare Business Codes Affect Your Taxes?

To help you really grasp the practical differences between these two codes, I've put together a table that breaks down the key distinctions. Taking a moment to understand this chart will make you feel much more confident and prepared when you eventually talk to a tax advisor. It will transform the conversation from something intimidating into a strategic discussion. Pay close attention to the rows on Value-Added Tax (VAT) and the tax-saving strategies, as this is where the magic really happens for your bottom line.

Category	Business Code 930205 (Other Beauty Services)	Business Code 930206 (Skincare Services)
Tax Type	Tax-Exempt Business	Taxable Business
Value-Added Tax (VAT)	Exempt (0%)	Taxable (10%)
Primary Services	Nail art, pedicures, basic hand/foot care	Skincare, waxing, eyelash extensions/lifts
Issued Documents	Invoice (no VAT)	Tax Invoice or Credit Card Receipt (showing VAT)
Tax-Saving Strategy	Advantageous for price competitiveness due to no VAT.	Allows for input tax credits; helps maintain simplified taxpayer status.

Why is the 'Taxable + Tax-Exempt' Combo the Ultimate Tax-Saving Strategy?

If you're still not quite seeing the full picture, let me break it down in the simplest terms possible. This is the core of the strategy. Most new business owners in South Korea want to start as what's called a 'simplified taxpayer' (gan-i-gwaseja). Think of this as a special, protected status for small businesses that makes your tax life dramatically easier. Instead of dealing with the standard 10% VAT on your taxable services, you pay a much lower rate (between 1.5% and 4%), and the reporting requirements are far less demanding. It's the ideal runway for getting your business off the ground. To qualify for and maintain this simplified status, your annual revenue from taxable goods and services must be less than 80 million Korean Won (roughly $60,000 USD, though this figure is just for general context).

Here’s where it gets really interesting. Let's create a detailed hypothetical to show you the power of this structure. Imagine your new beauty business has a fantastic first year and you earn a total of 95 million KRW.

Now, let's explore how registering as a 'dual-status business' (known as a gyeom-yeong sa-eopja), one that offers both taxable and tax-exempt services, completely changes the game. Let's say you have the exact same fantastic year, earning a total of 95 million KRW in revenue. However, because you wisely registered both codes from the start, your revenue is now broken down like this:

- Nail & Pedi Services (from Tax-Exempt Code 930205): 70 million KRW

- Eyelash Extensions & Waxing (from Taxable Code 930206): 25 million KRW

Now, here is the multi-million-won secret: When the National Tax Service (NTS) determines whether you still qualify as a 'simplified taxpayer,' they look only at your revenue from taxable services. Your 70 million KRW from your bustling nail business is completely ignored for this specific calculation. The only figure they care about for this threshold is the 25 million KRW from your taxable services. And what is 25 million KRW? It is far, far below the 80 million KRW threshold. The result is incredible. You get to keep your 'simplified taxpayer' status for much longer. You continue to enjoy the significantly lower tax rates and simpler paperwork, even as your total business income grows well past the 80 million KRW mark. You have successfully and legally structured your business to minimize your tax burden while maximizing your growth potential. This isn't some shady loophole; it's a legitimate strategy built into the tax code. The official 2026 guidelines on business type transitions from the NTS explicitly state that for dual-status businesses, the simplified taxpayer status is determined based on the revenue generated from taxable supplies only. This is precisely why we need to be strategic and intelligent about our business structure from the very first day. It’s about building a system where you can actually pay less in taxes as you earn more money.

How Can You Add a Business Code in 5 Minutes on Hometax?

Did you already finish your business registration and only signed up for one code? Don't worry. You can easily add a secondary business code from the comfort of your home using Hometax, Korea's official online tax portal. The owners of the one-person salons I mentor have all done this in under five minutes. Just follow these steps:

- Log into Hometax: Go to the Hometax website and log in using your Joint Certificate (gongdong-injeungseo, the new name for the old public certificate) or another financial certificate.

- Navigate the Menu: From the top menu, click through the following path: [National Tax Certificates·Business Registration·Tax-Related Applications/Reporting] → [Business Registration Application·Correction·Closure] → [Correct Business Registration (Individual)].

- Select Your Business: Enter your business registration number, select it from the list, and click 'Inquire'.

- Enter/Modify Business Type: Look for the 'Enter/Modify Business Type' button in the middle of the screen. Click it. In the 'Secondary Business Type' section, use the 'Search Business Code' function to find and add 930206 (Skincare Services) or 930205 (Other Beauty Services), whichever you're missing. Make sure both your primary and secondary codes are listed correctly.

- Final Submission: Review the remaining information, click 'Save and Next,' and submit the application. You'll typically receive a text message confirming the change has been processed within 1-3 business days.

Putting off this simple process could cost you dearly later. If you generate taxable revenue without being registered for it, you could face penalty taxes and other complications. I strongly recommend taking care of this right after you finish reading this article.

Your Top Questions, Answered (FAQ)

Q. I'm just a one-person shop and my sales will be tiny at first. Do I really need to register both codes right away?

A. Yes, I absolutely recommend registering both from the very beginning. First, the process of correcting your business registration later is an administrative hassle you don't need. More importantly, you never know when a new opportunity for service expansion will arise. A loyal client might ask if you offer waxing, or a new beauty trend could emerge that you want to capitalize on immediately. Being prepared from day one means you can be agile and responsive, capturing that new income stream without any bureaucratic delays.

Q. What are the specific penalties for reporting the wrong business code?

A. The biggest issue is the 'penalty tax' (known as gasanse in Korean). Let's say you're registered only as a tax-exempt nail salon, but you perform a waxing service, which is a taxable activity. This is considered a failure to report taxable income. In this situation, not only would you have to pay the original 10% VAT you should have collected, but you'll also be hit with an additional 'failure to file' penalty tax and a 'late payment' penalty tax. The penalties can quickly add up to be much more than the original tax owed, creating a massive and unnecessary financial headache.

Q. Can I switch my primary and secondary business codes later on?

A. Yes, absolutely. You can use the same 'Correct Business Registration' menu on the Hometax portal that I described earlier to switch your primary and secondary codes at any time. This is a common and smart business practice. For example, if you find that your revenue from waxing and eyelash services starts to consistently exceed your nail art revenue, it would be wise to update your registration to reflect that skincare is now your primary business activity.

The era of succeeding in the beauty industry with technical skills alone is over. True, long-term success requires you to view your business as a complete system, encompassing everything from founder education (like what we do at Beauridge), to talent recruitment (via Beauty Job Manager), and even marketing automation (with 1004ai). Choosing the right business codes today is the foundational first step in building that robust system. If you have any more questions, please don't hesitate to leave a comment below. I'll personally read and answer every one.

Don't hesitate. Open your business plan right now and write down 'Primary Code: 930206' and 'Secondary Code: 930205'. This small action is the most reliable vaccine against future tax headaches.
