Columbia, SC Business License Guide

What does this mean for me?

The Columbia business license is one layer in a stack. It does not prove that your site is properly zoned, your build-out passed inspection, your food operation is permitted, or your state tax accounts are complete. Confirm the location and zoning first, then finish the City, state, and activity-specific steps that fit your facts. For the broader map, see our guide to city, county, and state registration and our South Carolina business license guide.

City of Columbia business license

The City calls the local requirement a business license. The Business Licensing site links the current application, renewal, payment, account-update, and closure paths. The self-service portal handles new applications and renewals.

The license tax depends on the business classification and applicable gross-income rules. Existing licensees renew using prior-year gross income. A business based outside Columbia reports the gross income attributable to work conducted inside City limits.

All Columbia business licenses expire April 30. The City’s renewal page says a 5% penalty applies after April 30 and another 5% is added each month thereafter until paid. Out-of-city businesses should renew before conducting business in the new calendar year.

The Business Licensing page still lists 1339 Main Street for in-person service while also carrying a move notice for 1401 Main Street. Confirm the current office location before visiting.

Zoning, building, fire, signs, and inspections

Check the property before you sign a lease, renovate, install a sign, or set an opening date. Columbia Zoning reviews business-license compliance and permit applications. The City’s UDO resources link to standards for home occupations, food trucks, short-term rentals, temporary vendors, signs, and other uses.

If construction or a change of occupancy is involved, use the City’s building codes and permit applications. A Certificate of Occupancy is separate from the business license, and building, trade, fire, or accessibility rules may also apply.

Home-based businesses

Columbia’s current home occupation standards require the principal operator to live in the dwelling. They allow no more than two nonresident workers on the premises and limit business use to 25% of the dwelling floor area or 1,000 square feet, whichever is less. The rules also restrict signs, outside storage, unusual traffic or deliveries, nuisance effects, and business vehicles.

Goods generally cannot be sold from the home except when incidental to a service. Motorized-vehicle manufacture, maintenance, or repair is not allowed as a home occupation. Home salons and barbershops require a Special Exception Permit. See our home occupation permit guide for background, but use Columbia’s UDO for the local rule.

Building-code change to watch now

The City says ICC A117.1-2026 became the applicable accessibility standard on September 18, 2026 where accessibility rules apply. It also says South Carolina’s 2024 code editions take effect January 1, 2027; permit requests after December 31, 2026 must follow the new editions, including the 2023 National Electrical Code as adopted with state modifications.

County requirements that may apply

Richland County

Do not add a Richland County license merely because Columbia lies in Richland County. The County license applies to covered business activity in unincorporated Richland County. A Columbia business may still need it when doing work in unincorporated county territory. New unincorporated-county businesses should use the current Richland County Business License page; existing licensees have a separate renewal path.

Lexington County

Lexington County’s current zoning FAQ says the County does not issue a county business license. Land-use activity in unincorporated Lexington County needs the applicable zoning permit, while municipalities control their own jurisdictions. Settle the exact jurisdiction before paying for a local license.

South Carolina registrations and tax accounts

Entity filing and business name

Corporations, LLCs, limited partnerships, and limited liability partnerships generally file organizing documents with the South Carolina Secretary of State. Sole proprietors and general partnerships do not file merely because they exist. Use Business Entities Online. Effective September 10, 2026, applicable online filing services added identity verification.

South Carolina has no general statewide DBA-registration process. Business One Stop says a DBA can generally be shown on local business-license and state tax records, while certain entity-specific assumed or fictitious names have separate rules.

Retail License and tax accounts

For taxable retail sales, check the SCDOR Retail License. SCDOR lists a $50 nonrefundable fee and says the license must be obtained before taxable retail sales begin. Apply through MyDORWAY. A service business does not automatically need a Retail License; the answer depends on whether the service is taxable. Online sellers can also see whether online businesses need a business license.

Professional and employer steps

Check SCLLR professions and occupations before offering regulated work. If you hire, SCDOR uses MyDORWAY for withholding; SCDEW uses SUITS for unemployment insurance; and employers must report new hires through SC New Hire Reporting within 20 days after the employee’s first day.

Federal steps

Many businesses need an Employer Identification Number. The IRS provides the EIN application directly and does not charge a fee. Businesses commonly need an EIN when they hire employees, operate as a corporation or partnership, or have certain federal filing duties.

FinCEN finalized its Beneficial Ownership Information rule in August 2026. The important chronology is that the practical exemption for U.S.-created companies already existed under the March 2025 interim rule. The August 2026 final rule made that exemption permanent; it did not suddenly create a new exemption for Columbia businesses during this review period. Current FinCEN BOI guidance says U.S. companies are exempt, while certain foreign companies registered to do business in the United States may still have reporting duties.

Special Columbia situations

Prepared food and hospitality tax

The City imposes a 2% local hospitality tax on covered prepared or modified food and beverages for immediate consumption, carry-out, or catering. Use the current hospitality tax page and City portal for reporting.

Restaurants and food trucks

Retail food safety is now handled by the South Carolina Department of Agriculture, not the former DHEC food-safety program. SCDA says covered restaurants, caterers, grocery food operations, food trucks, and other retail food establishments need the appropriate Retail Food Establishment Permit before selling food direct to consumers.

Columbia’s food-truck guidance lists the City business license, a $10 zoning fee, private-property permission, and City fire inspection. Its page still contains old DHEC wording, so use SCDA for the current state food-safety path. See our food truck license guide for broader planning.

Short-term rentals

Columbia says an STR needs an STR permit and business license, with location controlled by the UDO. A pre-window current-law correction matters here: Ordinance 2026-013, approved March 3, 2026, lets an owner-occupied dwelling in a residential zoning district operate as an STR without the otherwise applicable four-lane-street frontage rule. See the current STR page.

If you sell or serve alcohol, check the SCDOR Alcohol Beverage Licensing path; the City business license does not replace the state alcohol license or permit. For temporary group events, arts-and-crafts events, and similar local event licensing, use Columbia’s Other Licenses & Permits page. Food vendors at events should also check SCDA food rules and City hospitality-tax duties.

Alcohol and temporary events

Future food rule

South Carolina’s shrimp-disclaimer law takes effect October 28, 2026. Covered food-service establishments serving ready-to-eat foreign imported shrimp should review SCDA guidance before that date.

Costs you can plan for

Do not build a startup budget from an old blog post. Some costs are flat, while others depend on revenue, activity, permit type, or project size.

The older version of this guide described the SCDA food cost as a flat $100 initial permit fee plus an annual inspection fee. The current SCDA public materials clearly publish the annual $100–$450 inspection schedule, but do not support using that old shortcut as the universal current startup amount. Use the current permit application for the new-establishment amount that applies to your filing.

Real-world examples

Home-based bookkeeper

Confirm City limits, check the home-occupation standards, and apply for the City business license. Customer traffic, employees, storage, signs, or a large business area can change the zoning answer.

Restaurant on Main Street

Expect to check the City license, zoning, occupancy/building and fire review, SCDOR Retail License, City hospitality tax, and SCDA food permit. A remodel may also be affected by the September 2026 accessibility update or January 2027 code transition.

Contractor based outside Columbia

Work inside City limits can trigger a Columbia business license even when the office is elsewhere. Also check SCLLR and job permits. Work in unincorporated Richland County can add a county license.

Short-term rental host

A platform listing is not enough. Check the City STR permit, business license, and location rule. The owner-occupied residential exception is specific; it does not approve every residential STR.

Online seller from home

Check the City license, home-occupation rules, and SCDOR Retail License rules. Marketplace tax collection does not automatically replace local licensing or every state filing.

A compact compliance checklist

• Confirm the exact physical address and jurisdiction.
• Check zoning before signing a lease or changing a property use.
• Check building, fire, sign, accessibility, and occupancy approvals.
• Apply for the Columbia business license before operating in City limits.
• Use the correct classification and gross-income period.
• File the state entity if your structure requires it.
• Handle DBA/trade-name information through the proper local and tax records.
• Set up SCDOR tax accounts when required.
• Check SCDA before opening a covered food operation.
• Check SCLLR before offering regulated work.
• If hiring, check withholding, unemployment insurance, and new-hire reporting.
• Get an EIN from the IRS if needed.
• Keep copies of approvals and agency messages.

What to do if this does not work

If you get conflicting answers, separate the issue: City licensing, zoning, building/fire, county jurisdiction, state tax, food safety, professional licensing, or employer registration. Ask the agency to name the exact permit, form, ordinance section, account, or inspection controlling the next step. Pause major spending when the unresolved issue could block the location, build-out, equipment, food process, occupancy, or regulated activity.
