Is an electronic signature valid?

Yes. Electronic signatures satisfy the ESIGN Act (15 U.S.C. ch. 96) and UETA in most states when intent, consent, attribution, and record retention are present. Exceptions such as certain court filings and testamentary documents may still require wet signatures.

What supporting documents should I attach?

Attach formation documents, EIN confirmation (IRS CP 575), articles of incorporation or organization, and a power of attorney if an agent signs. For sales tax or payroll registrations include any state-specific forms and required licenses.

Who has authority to sign?

An authorized officer, owner, or an agent with a written power of attorney can sign. Verify authority under corporate bylaws or the operating agreement; mismatched signer names can lead to rejection or processing delays.

Consequences of incorrect or missing data

Incorrect TINs, name mismatches, or omitted fields can trigger backup withholding, penalties under IRC §6721, or rejected registrations. Correct errors promptly and keep copies of corrected submissions for audit trails.

Are notarization or witnesses required?

Most Business Tax Applications do not require notarization. Certain state filings or accompanying affidavits may. Many states accept remote online notarization subject to identity proofing and retention rules; confirm with the state notary commission.

How long must records be retained?

Retain completed applications and supporting records per IRS rules (minimum three years; six years if income is substantially understated). Industry rules such as HIPAA, SEC, or state law may require longer retention.

Entity Registration Information

Tax Types

Select the account types you're applying for. You must pay any applicable license fee before the SCDOR processes your application and issues your license.

Sales & Use Tax

The Sales & Use Tax category contains several Sales & Use subtypes. Included in this category, for the purpose of the SCDOR-111 application, are Accommodations, Artist & Craftsman, Aviation, Max Tax, Retail, and Use Tax. See Section D, Box 9 for more details.

Withholding Tax

Withholding Tax is taken out of employees wages to go towards the employees' total yearly Income Tax liability. Every employer/withholding agent that has an employee earning wages in South Carolina (and who is required to file a return or deposit with the IRS) must file a Withholding Tax return with the SCDOR for any taxes that have been withheld for state purposes.

South Carolina requires withholding from:

● wages

● prizes

● royalties

● winnings

● nonresident contractors (for contracts exceeding $10,000)

● rental payments made to nonresidents who own five or more residential units or one or more commercial properties in South Carolina

● net proceeds going to nonresident sellers of real estate and associated tangible personal property located in South Carolina

Nonresident Withholding Exemption

South Carolina requires employers to withhold Income Tax from certain payments made to nonresidents. Nonresidents who have activity but no employees in South Carolina can be granted an exemption from this requirement. Provide a completed I-312, Affidavit of Registration, to the employer or withholding agent with whom you are contracting. Do not submit the I-312 to the SCDOR.

What the Business Tax Application Is and When It’s Used

The Business Tax Application is a standardized document businesses complete to register for tax accounts, report withholding, or provide information necessary for state and federal tax administration. It commonly accompanies employer registrations, state sales tax permits, or requests for taxpayer identification and may be used by payroll providers, accounting departments, and third-party filers. Completed applications establish filing obligations, enable withholding and reporting, and create a record of taxpayer information. This page explains fields, timing, supporting documents, and electronic submission considerations relevant to U.S. federal and state tax requirements.

Why a Correct Business Tax Application Matters

A Business Tax Application centralizes taxpayer details, reduces errors, and documents obligations required by IRS and state revenue agencies. Completing it correctly minimizes penalties, ensures accurate withholding and reporting, and supports audit readiness for payroll, sales tax, and entity-level filings across jurisdictions.

Who Typically Completes a Business Tax Application

Common users include owners, controllers, payroll administrators, CPAs, and state tax officials responsible for registration, withholding, and reporting.

Small-business owners managing employer accounts and sales tax registrations directly.
Payroll teams and payroll providers completing withholding setup and reporting.
Accountants and CPAs preparing filings and verifying taxpayer identification numbers.

Determine the right signer and filing destination early to meet IRS and state deadlines and avoid backup withholding.

Omitting required supporting documents such as articles of organization or authorization letters leads to rejected registrations or requests for additional documentation from state agencies.
Using inconsistent signer authority without a power of attorney or corporate resolution can result in rejection and delays when agencies validate signature authority.
