Mount Pleasant Business License: OPAL Portal, Rates and Home Businesses

Opening a business in the Town of Mount Pleasant means dealing with the town's Business License Division. South Carolina does not issue a general business license, and a filing with the Secretary of State does not satisfy the town. This guide covers how to get a mt pleasant business license through the OPAL portal, how the license tax is calculated, how renewals work, and what to check if you run a business from home or plan a short-term rental.

Informational note: This article is informational content, not legal or tax advice. Rates, rules and deadlines change, so confirm anything that affects your money or your legal exposure with the Business License Division, and consult a qualified attorney or CPA for complex situations.

What you need before you start

Gather these items first. Most delays come from missing information, not from the application itself.

• Your legal business name and entity type. If you formed an LLC, have your filed Articles of Organization ready. The South Carolina filing fee for a domestic LLC is $110, filed through Business Entities Online at https://businessfilings.sc.gov/.
• Your federal EIN, if you have one. Use the same legal name on every form.
• The physical address where you will operate, plus a mailing address.
• An estimate of gross receipts for the license year. The license tax is based on this figure.
• A plain description of your business activity, written clearly enough for the office to classify it.
• Owner or member information, with contact details and identification.
• A lease or property owner contact if you rent the space.
• Zoning confirmation if you plan to work from home or rent a property short term (see Step 2).
• An SCDOR Retail License if you sell tangible goods. This is a one time, nonrefundable $50 fee per location, applied for through the Business Tax Application on MyDORWAY at https://dor.sc.gov/.

Step 1: Confirm the town is the right jurisdiction

A Mount Pleasant business license covers businesses inside town limits. A Charleston County address outside the town may fall under a different local tax. Charleston County is one of nine South Carolina counties that levy a local business license tax, so an address just outside the town line can mean a county license instead. Confirm your address before you apply, because a license from the wrong jurisdiction does not protect you in the right one.

Step 2: Check zoning before you apply

Mount Pleasant zoning controls what you can do at a specific address. Home occupations and short-term rentals each carry their own conditions. Do not assume the license application confirms that your use is allowed. Contact the town's zoning staff with your exact address and a short description of the activity, and ask for the answer in writing if you can. Ask whether a home occupation needs any approval beyond the license, and what the short-term rental rules require for your property type.

Step 3: Estimate gross receipts and find your rate

For the 2026-27 license year, the Class 1 schedule is $40 on the first $2,000 of gross receipts, plus $1.54 per $1,000. A 70 percent rate applies to gross receipts above $3 million. Non-residents pay double. The examples below assume the per-thousand charge applies to receipts above the first $2,000, so confirm that method with the Business License Division. Your classification determines which schedule applies, so have the office confirm your class before you pay.

Gross receipts (resident, Class 1)	Estimated license tax
$2,000	$40.00
$50,000	$40 + (48 x $1.54) = $113.92
$100,000	$40 + (98 x $1.54) = $190.92

Non-residents pay double the resident amount, so a $100,000 non-resident business would owe roughly twice the resident figure.

Step 4: Apply or renew in OPAL

OPAL is the Town of Mount Pleasant's online permitting system, and it is where you apply for a new license and renew an existing one. Reach it from the town's official website, not from a search result or a third-party license service, which may charge extra or show outdated dates. The general sequence is:

1. Create an account and confirm your email address.
2. Start a new business license application and enter your legal name, entity type, business address and mailing address.
3. Enter your classification and gross receipts estimate. Use a number you can support with your books, not a figure you hope to beat.
4. Upload or enter supporting information, such as your entity documents and zoning confirmation. Screens and required fields change, so follow the prompts closely.
5. Review, pay and save the confirmation. Keep a copy of the confirmation and the license once it is issued.

If you get stuck, contact the Business License Division at 100 Ann Edwards Ln, Mount Pleasant, SC. Ask for current processing times before you set a launch date.

Step 5: Account for hospitality and accommodations taxes

Certain businesses owe a 2 percent hospitality tax. Those businesses report and remit it monthly to Charleston County, which acts as the collection agent. Put the monthly remittance date on your calendar from the day you open, because it runs separately from your annual license.

The town also has an accommodations tax ordinance. Ask the Business License Division for the current accommodations tax rate and whether it applies to your lodging activity before you list a property. Do not rely on a rate you found on an older website.

Step 6: Layer in the state requirements

A Mount Pleasant license is local only. Depending on your business, you may also need:

• Secretary of State filings: An LLC or corporation must file its formation document. South Carolina LLCs file no annual report. A corporation files a one time Form CL-1 with a $25 initial License Fee within 60 days of doing business in the state, then files an annual report with its tax return. See https://sos.sc.gov/online-filings/business-entities for details.
• No state DBA: The Secretary of State does not register DBAs. There is no separate local DBA filing either. Show the trade name on your local business license, and list it on your EIN application and SCDOR Business Tax Application.
• Retail food: Retail food permits come from the South Carolina Department of Agriculture, not DHEC, which was split in 2024.
• Contractors: A commercial contractor license is required for work above $10,000. A residential specialty registration applies above $500. Confirm current requirements with the state agency that licenses contractors before you take a job.
• Sales tax: Sellers of tangible goods need the $50 Retail License described above. The state sales tax rate is 6 percent.

Step 7: Renew on time

The license year runs May 1 to April 30, and renewals are due April 30. Some third-party sites still list July 31 deadlines. Those dates are out of date. Ask the Business License Division for the late payment rules before you miss one.

If you are unsure which portal handles a renewal, the SC Revenue and Fiscal Affairs Office directs local renewals to localblrenewal.com. Mount Pleasant participates in that portal, so you can renew there or through OPAL.

Expected results

Following these steps typically means you apply to the right jurisdiction, submit a documented gross receipts estimate, and have a zoning answer in hand before you spend money on signage, inventory or a lease. This process may also reduce the chance of a returned application or an unexpected bill. Results depend on your business type, property and classification, so treat these outcomes as likely rather than guaranteed.

Common mistakes to avoid

• Trusting a July 31 renewal date from a third-party site. The deadline is April 30.
• Estimating gross receipts too low. The tax is based on that figure, and an understated estimate may need correcting later.
• Assuming a Secretary of State filing is your local license. Business One Stop states that Secretary of State registration is not a business license.
• Starting a home business or short-term rental without a zoning answer.
• Forgetting the non-resident rate if your business has no fixed location inside the town.
• Paying through a lookalike website instead of the town's official access to OPAL.
• Missing the monthly hospitality tax remittance to Charleston County.

Tips for a smoother process

• Get the zoning answer first. It is the item most likely to change your plans.
• Save gross receipts records monthly so your renewal estimate is easy to support.
• Set calendar reminders for the monthly hospitality tax date and for April 30.
• Ask for the current accommodations tax rate in writing.

For a Mount Pleasant business with property, lodging, food or contracting questions, a short consultation with a qualified attorney or CPA is worth the cost before you open. This article is informational, not legal or tax advice.
