How to Start a Hair Extensions Business in South Dakota: Licenses, Costs & Requirements

South Dakota writes extensions into its cosmetology statute by name. Section 36-15-2 lists weaving, extending and fusing among the acts of cosmetology, so the full 1,500 hour cosmetologist license is the credential behind bonded, taped and sewn installs alike, and no narrower or specialty license exists. One door stands open beside it: the natural hair braiding exemption, whose definition covers extending and weaving hair extensions by hand or with thread, and ends where chemical joining agents begin. This guide walks through the license, the boundary, the licenses for the space, and the business setup behind the chair, including a sales tax that reaches the service ticket itself.

Who regulates hair extensions in South Dakota

One body runs South Dakota beauty licensing: the Cosmetology Commission, a five member commission continued within the Department of Labor and Regulation under section 36-15-5.1. It administers South Dakota Codified Laws chapter 36-15, which licenses cosmetology, esthetics and nail technology, and its rules sit in Article 20:42 of the Administrative Rules of South Dakota. It examines and licenses practitioners, licenses and inspects salons, booths and schools, and publishes each license's scope of practice. Official text: SDCL chapter 36-15 at the legislative research site, and the Cosmetology Commission pages at the department.

Extensions land squarely inside that framework because the statute names the work. Section 36-15-2(1) defines the practice of cosmetology to include hair care by braiding, twisting, weaving, extending and fusing, among a longer list of hair services. The commission's own homepage repeats that same list as what it regulates when the work is done for a fee. Barbering sits outside the commission, under the Board of Barber Examiners, and barbers are exempt from chapter 36-15 under section 36-15-16, so there is no barber route into extension work on this page. The rest of your setup spreads across the Secretary of State, the Department of Revenue and the department's wage and reemployment programs, plus a local layer from your city.

The license question: the cosmetologist license, and the routes that stop short

South Dakota does not leave extension work to inference. The cosmetology definition in section 36-15-2(1) names weaving, extending and fusing in its own words, and section 36-15-2.3 bars practicing cosmetology for compensation without a license. That one sentence decides the licensing strategy for the whole business: the cosmetologist license is the credential, and everything else in the chapter either stops short of hair or leads back to it.

The cosmetologist application under section 36-15-17 requires you to be at least 18 years old under section 36-15-15 and to show 1,500 hours of education in a licensed cosmetology school or a completed apprenticeship. The examinations are the NIC national written theory examination and the South Dakota Laws and Rules examination. The examination and the initial license together cost $120, a retake costs $90, and the license renews every year on or before your birth date for $45, with a $30 penalty after it. The license issues as a one time paper license with a QR code; a license lapsed under five years renews with a penalty for each expired year, and one lapsed longer means retaking both examinations. The commission's Frequently Asked Questions page covers the process.

School is not the only road. Section 36-15-45 sets the cosmetology apprenticeship at 1,500 consecutive hours of education in the same licensed apprentice salon, the same total as the school route. An apprentice license is available from age 17 and costs $25, the salon must hold an apprentice salon license at $300, and the apprentice trains under a licensed instructor at least 40 hours a week. On completion, a temporary license runs until the next examination, and the road ends at the same two examinations as school.

There is no shortcut credential hiding in the chapter. No weaving or extensions license or endorsement appears anywhere in chapter 36-15 or the commission's rules. The commission offers three licenses, cosmetology, esthetics and nail technology, and cosmetologists may practice all services covered by the three. The only service certifications the commission adds on top of a license are eyelash extensions, microdermabrasion and electric nail filing, and hair extensions is not one of them. The narrower licenses stop well short of the chair you are staffing: esthetics under section 36-15-2.2 is skin care only, and the section states expressly that esthetics does not include scalp treatments or scalp massage. A nail technician license reaches nails only. Neither licensee can legally install hair; on your team, the installs belong to your cosmetologists.

Hiring from out of state runs through reciprocity under section 36-15-19.2. The commission licenses a person holding a current license from another jurisdiction with substantially equivalent requirements, and a 2026 amendment lets an applicant whose license falls short make up the gap with documented work experience, credited at two hours per education hour up to 750 hours for cosmetology. Verify the license and its scope with the commission before any hire's first install.

The braiding boundary: where the exemption ends

Beside the license sits one genuine exemption, and for braid anchored installs it is the most valuable paragraph in South Dakota law. In 2017 the legislature added sections 36-15-1.1 and 36-15-16.1 to the chapter. Section 36-15-16.1 provides that any person engaging solely in natural hair braiding as defined in section 36-15-1.1 is exempt from the provisions of the chapter entirely. Before 2017, braiders in South Dakota needed the full cosmetology license. An exempt braider needs no license, registration, course or fee, and a braiding only studio needs no salon license either, because premises licensing attaches to the licensed practices. Our South Dakota braiding guide covers the exemption as a business in its own right.

The definition is written broadly enough to reach installs. Section 36-15-1.1 defines natural hair braiding as a form of hair manipulation that results in tension on hair strands by beading, braiding, cornrowing, extending, lacing, locking, twisting, weaving or wrapping human hair, natural fibers, synthetic fibers or hair extensions, by hand or with clips, combs, hairpins or thread. Topical agents are inside the definition too: conditioners, gels, moisturizers, oils, pomades and shampoos. Because thread is a listed tool, a sew-in built on braided tracks and attached with needle and thread sits inside the definition's own terms.

The exemption ends at three edges, and an extensions business should learn all three. First, joining agents: the definition states that natural hair braiding does not involve chemical hair joining agents, along with penetrating chemical treatments, coloring agents, straightening agents, permanent waves and bleaching agents. Tape-in installs and keratin or fusion bonded installs therefore fail the definition, and fusing is independently a named act of cosmetology in section 36-15-2(1). Second, cutting is not a braiding technique, and it is named cosmetology work. Third, the word solely: a mixed menu is not partly exempt, and the first bonded install, cut or color service brings the practitioner license and the salon license with it.

Plan the menu before the team, because braiding businesses drift: if your menu will ever include bonded installs, cutting or color, staff with cosmetologists and license the space from day one; if it stays braid anchored and thread attached, the exemption is complete, and the discipline is keeping it that way.

Your space: the salon, booth and limited salon licenses

Licensed extension work needs a licensed room, and section 36-15-51 gives South Dakota four salon and booth license types. A full menu studio takes the cosmetology salon or booth license. A studio that does installs and little else applies for the limited salon or booth license, where cosmetology is limited to one or a few of the practices listed in section 36-15-2, the application states the practices the studio will provide, and practicing beyond those stated limits is prohibited. The license costs $75 and opens on a 90 day permit: the business may not open until the permit arrives by mail and is posted, and the inspection happens inside the 90 days. The license expires on the anniversary of the opening date and renews at $55, with a $30 penalty after the date. It belongs to the original owners at the original address, so a move or a change of ownership means a new license under section 36-15-51.1, with another 90 day inspection window. Working space runs a minimum of 120 square feet for the first licensee plus 60 for each additional licensee, and each unique postal address needs its own license. The full walkthrough is in our South Dakota hair salon guide.

Section 36-15-54 confines cosmetology, nail technology and esthetics to a licensed salon or booth, with narrow exceptions for demonstrations, limited mobility clients and special events, each documented through a salon or booth. The special events list itself names weaving, extending and fusing, a small confirmation that the chapter treats installs as salon work wherever they happen. A home studio needs the same salon license, a separate outside entrance, complete separation from living quarters, and a local ordinance check.

The salon license licenses the premises, not the owner's hands: anyone may own the space, but every person installing hair inside it works under the personal license covering that service. A booth is an independent person salon inside a salon, registered under the host salon's license, and the booth licensee holds a booth license at the same $75 to open and $55 to renew, plus her own personal license. Employees working on a W-2 need no booth license. Since 2025, section 36-15-51.3 also lets licensees share a work station under set conditions, each holding a booth license for services inside a booth. The rule survives every arrangement: the space is licensed, and so is every set of hands.

Forming your LLC with the South Dakota Secretary of State

Many extensions studios form a limited liability company, and South Dakota's filing is cheap. Articles of Organization filed online with the Secretary of State cost $150, or $165 on paper. The state publishes its fee schedule on its official filing fees page. Your registered agent must be a South Dakota resident with a physical and mailing address in the state; a PO Box alone will not serve. The annual report is due the first day of the anniversary month of the month you formed, with filing opening two months early, and it costs $55 online or $70 on paper. Miss it and a $55 late fee applies; let the company be administratively dissolved and reinstatement costs $150. Every figure above is the state's. Our South Dakota LLC guide covers the formation sequence in full.

Registering your business name with a fictitious name statement

South Dakota's name rule turns on whether the name is already on file with the Secretary of State. An LLC trading under its own legal name needs no further filing. A fictitious name statement under section 37-11-1 is required when your operating name does not plainly show each owner's true surname and the name is not on file, which covers most sole proprietors and partnerships trading under a brand name, and any LLC rebranding under a different name. The statement files with the Secretary of State online or with any county register of deeds, costs $10, and renews every fifth year. Operating without a required statement is a Class 2 misdemeanor, and a change in the persons owning or operating the business of 25 percent or more means filing a fresh statement. Treat the $10 filing as part of any rebrand, not an afterthought.

Getting your federal Employer Identification Number

Your EIN is the business's federal tax identity, and you will use it to open the business bank account, run payroll and file federal returns. Apply directly with the IRS on the official EIN application page. It is free, and you should never pay a third party site that imitates the application. Banks, hair suppliers and most landlords will ask for an EIN even when the tax rules would let you use a Social Security number, so get one at formation.

South Dakota sales tax: the tax that reaches the install itself

South Dakota is one of the states that taxes services, and beauty services are squarely inside it. The Department of Revenue's guidance for the trade states that services provided by cosmetologists, barbers, nail technicians and estheticians are subject to sales tax. So the install itself is taxed, not just the hair on the shelf. The state rate is 4.2 percent, plus a municipal tax of 1 to 2 percent in cities that impose it, at the rate of the city where the service is received. One date matters here: the 4.2 percent state rate is temporary, and it returns to 4.5 percent on July 1, 2027. Keep the department's beauty salons tax fact at the front desk.

Three mechanics follow. First, hold a sales tax license from the Department of Revenue before your first taxable sale; it carries no application fee and is not transferable, so an ownership or entity change means a new license and a final return on the old one. Second, the salon is the consumer of products it uses in a service: hair and supplies bought without tax and consumed in an install owe use tax, while products sold to clients are taxable retail sales you can buy for resale with an exemption certificate. How you price and itemize the hair against the labor is a real bookkeeping decision, and it should be made with the tax fact open. Third, the small rules add up: voluntary tips are not taxed, mandatory service charges are taxable gross receipts, gift certificates are taxed at redemption rather than at sale, and records stay for at least three years. South Dakota has no state income tax; the sales and use tax is the state tax your studio lives with.

Booth renters run their own tax lives: each holds her own sales tax license and remits on her own receipts, booth rent itself is not taxed, and rent paid is not deductible from her gross receipts. Put the tax split in the booth agreement so nobody assumes the salon's license covers the renter's book.

Hiring stylists: employees, booth renters and reemployment assistance

When you hire, you register as an employer with the Department of Labor and Regulation and pay reemployment assistance tax, South Dakota's unemployment program. The tax applies to the first $15,000 of wages paid to each employee per year. A new non-construction employer pays 1.20 percent plus a 0.55 percent investment fee in the first year, then 1.00 percent plus the same investment fee in years two and three, and an experience rate between 0 and 9.5 percent after that. The minimum wage is $11.85 an hour from January 1, 2026, set by section 60-11-3.2 and adjusted each year, with a tipped cash wage of $5.925; the department has listed $12.30 from January 1, 2027. Because South Dakota has no state income tax, there is no state withholding to set up alongside the federal.

Extensions studios lean on booth rent, and South Dakota gives the model an objective marker most states lack: a true booth renter holds her own booth license and her own personal license, sets her own prices and hours, collects her own receipts and remits her own sales tax. An operator whose schedule, prices and product lineup you control looks like an employee whatever the paperwork calls her. Put booth agreements in writing and treat classification as a legal decision, not a payroll preference.

City zoning, occupancy and local permits

State licenses do not guarantee your location is legal. Your city controls zoning, and an extensions studio has to be a permitted personal services use at the address you choose, so confirm the zoning before you sign a lease rather than after. Cities commonly add a local business license, building and signage permits, and occupancy inspections tied to the build out, and home based studios meet local rules on top of the commission's separate entrance and separation requirements. Check zoning before the lease, not after: a cheap space in the wrong category is not cheap once you have paid for chairs, mirrors and a sign you cannot legally use.

Insurance and the costs that keep coming back

Nothing in chapter 36-15 conditions your licenses on carrying liability insurance, so coverage is a business decision rather than a licensing one. Studio owners typically shop for general liability, professional liability covering the install work itself, and property coverage for the build out, chairs and retail inventory. Extensions businesses carry one inventory exposure most salons do not: the hair itself is expensive stock, held for specific clients and often prepaid, so ask how your property policy treats client hair stored on the premises. One South Dakota rule sharpens the decision: employers here are not required to carry workers compensation insurance, but an employer without it can be sued civilly by an injured employee, so going uninsured is a documented choice, not a default. Require booth renters to carry their own professional liability as a term of the booth agreement. Premiums vary widely with your city, menu and team size, so this guide does not quote benchmark prices. The deeper walkthrough is in our South Dakota hair salon insurance guide.

Your recurring state costs are small and predictable: practitioner renewals on each licensee's birth date, the salon renewal on the opening anniversary, the LLC annual report, and sales tax remitted on services and retail alike. The expensive mistakes in a South Dakota extensions launch are almost never state fees. They are the bonded install booked under the braiding exemption, the renter treated as covered by the salon's tax license, and the lease signed before zoning was checked.

Dates to put on your calendar

• On each licensee's birth date, every year: cosmetologist license renewal, $45, to the Cosmetology Commission, with a $30 penalty after the date.
• On the opening anniversary, every year: salon, booth or limited salon license renewal, $55, to the Cosmetology Commission.
• The first day of the anniversary month, every year: LLC annual report to the Secretary of State, $55 online or $70 on paper, with filing opening two months early.
• Every fifth year: fictitious name statement renewal, $10, if your business trades under a filed fictitious name.
• On the Department of Revenue's schedule: sales and use tax returns and remittance for services and retail sales, at your assigned filing frequency.
• July 1, 2027: the state sales tax rate returns from 4.2 percent to 4.5 percent; update your register rates and your price quotes before the date.
• Every January 1: check the new minimum wage; the Department of Labor and Regulation has listed $12.30 from January 1, 2027.
• Within 20 days of each hire: new hire report to the Department of Labor and Regulation.
• Before you add a service: recheck sections 36-15-2 and 36-15-1.1 whenever your menu changes, especially before adding bonded installs, cutting or chemical services to a braiding based studio.

Frequently asked questions

Do I need a license to install hair extensions in South Dakota?

For most methods, yes. Section 36-15-2(1) of the South Dakota Codified Laws counts hair care by weaving, extending and fusing among the practices of cosmetology, and only a licensed cosmetologist may perform them. The exception is narrow: an install that stays inside the natural hair braiding definition in section 36-15-1.1, attached by hand or with clips, combs, hairpins or thread and using no chemical joining agents, is exempt under section 36-15-16.1.

Is there a specialty hair extensions or weaving license in South Dakota?

No. The Cosmetology Commission licenses three practices, cosmetology, esthetics and nail technology, plus instructors, students and apprentices, and none of them is an extensions credential. The only service certifications the commission adds to a license are eyelash extensions, microdermabrasion and electric nail filing. Weaving and extension work sit inside the cosmetologist license, which also covers every service in the other two licenses.

Can I do sew-in weaves without a license under the braiding exemption?

Yes, if the install stays inside the definition and braiding is all you do. Section 36-15-1.1 defines natural hair braiding to include extending and weaving human hair, natural fibers, synthetic fibers or hair extensions by hand or with clips, combs, hairpins or thread, and section 36-15-16.1 exempts a person engaging solely in natural hair braiding from the chapter entirely. The exemption ends at chemical hair joining agents such as tape and keratin or fusion bonds, and at cutting, coloring and chemical services, which are cosmetology.

What license does an extensions only studio need for its space in South Dakota?

A salon or booth license from the Cosmetology Commission under section 36-15-51. A studio offering the full cosmetology menu takes a cosmetology salon license; a studio limited to one or a few of the practices in section 36-15-2 applies for a limited salon or booth license and states the practices it will provide. The license costs $75 and opens on a 90 day permit that must be received and posted before the first client, then renews at $55 on the anniversary of the opening date. Cosmetology may only be practiced in a licensed salon or booth under section 36-15-54.

Are hair extension services subject to sales tax in South Dakota?

Yes. South Dakota taxes services, and services provided by cosmetologists are subject to the 4.2 percent state sales tax plus 1 to 2 percent municipal tax where the city imposes it. The 4.2 percent state rate is temporary and returns to 4.5 percent on July 1, 2027. Hair and products you sell at retail are taxable sales as well, while hair and supplies your business consumes in a service are subject to use tax. Booth renters hold their own sales tax licenses and remit on their own receipts.

Can I reach the cosmetologist license through an apprenticeship instead of school in South Dakota?

Yes. Section 36-15-45 sets the cosmetology apprenticeship at 1,500 consecutive hours in the same licensed apprentice salon, the same total as the school route. An apprentice license is available from age 17 and costs $25, the salon must hold an apprentice salon license at $300, and the apprentice trains under a licensed instructor at least 40 hours a week. The apprenticeship ends at the same examinations as school: the NIC written theory examination and the South Dakota Laws and Rules examination.
