A South Carolina business facing a sales tax audit should gather its SCDOR notice, filed tax returns, sales reports, purchase invoices, exemption certificates, and supporting accounting records. The specific documents required depend on the audit’s scope and the transactions being examined.
Organizing South Carolina sales tax audit records early helps business owners identify reporting differences, document tax treatment, and prepare accurate responses. At Ligon Business & Estate Law, we help Rock Hill and York County businesses understand audit requests, evaluate potential tax liabilities, and address disputes with the South Carolina Department of Revenue (SCDOR).
What Does the Audit Notice Request?
The first step after receiving an audit notice is to read the entire document and identify what the SCDOR is requesting.
The South Carolina Department of Revenue administers state sales and use taxes. Its audit process is separate from a federal income tax audit conducted by the Internal Revenue Service (IRS), although information from other agencies may sometimes be relevant.
According to the SCDOR’s audit process guidance, the department conducts field audits and desk examinations.
A field audit may involve a detailed review of business records, while a desk examination generally focuses on specific returns or reporting questions.
Information to Check Immediately
Before gathering documents, identify:
- Tax periods: Which months, quarters, or years are being examined?
- Tax accounts: Does the notice concern sales tax, use tax, or another obligation?
- Requested records: Which reports, invoices, or supporting documents must be provided?
- Response instructions: Where and how should the documents be submitted?
- Deadlines: What date does the notice establish for responding?
- Auditor contact: Who is handling the examination?
Keep the original notice and maintain copies of all communications.
An initial audit request is not necessarily a proposed assessment. The deadline for supplying documents may differ from the legal deadline for protesting a proposed tax assessment.
Business owners should avoid assuming that every SCDOR notice follows the same timeline.
Which Sales and Return Records Should Be Reconciled?
One of the central tasks in preparing sales tax audit documentation is comparing sales activity with the amounts reported on filed returns.
Auditors may examine whether recorded transactions support reported gross sales, deductions, exemptions, and taxes.
The goal is to establish a clear connection between the company’s transaction records and its tax filings.
Gather Sales and Accounting Reports
Businesses should locate records for the periods identified in the notice, including:
- Filed South Carolina sales and use tax returns
- General ledger and sales revenue reports
- Point-of-sale transaction summaries
- Customer invoices and receipts
- Merchant processor and payment platform statements
- Refunds, returns, and credit memos
- Sales tax liability reports
- Records of tax payments and adjustments
A Rock Hill retailer, for example, might accept payments through a storefront register, an online store, and third-party payment platforms.
Each system may produce a separate sales report. Those reports should be reviewed together to determine whether all relevant transactions were properly reflected in filed returns.
Explain Differences Between Records
Accounting reports do not always match tax returns without adjustments.
A payment processor may report gross transactions before deducting processing fees. Accounting software may group deposits by settlement date rather than transaction date.
Other differences can arise from refunds, canceled sales, timing adjustments, or transactions recorded outside the usual sales system.
Business owners should document these differences instead of changing historical figures simply to make reports match.
A useful reconciliation connects recorded sales to reported amounts and explains supported adjustments.
The SCDOR generally requires businesses to retain tax records for at least four years after the applicable return was filed or due, whichever is later, under South Carolina Regulation 117-200.1. Longer retention may be necessary when an audit, dispute, or other applicable requirement remains outstanding.
How Should Exemption and Resale Documents Be Organized?
Sales that were not taxed may receive particular attention during an audit.
A business that treats a transaction as exempt should be prepared to explain the legal basis and provide documentation supporting that treatment.
Keep Resale Certificates With Relevant Sales
South Carolina uses Form ST-8A for qualifying resale transactions.
A properly completed resale certificate helps a seller document that a purchaser acquired qualifying property for resale, lease, or rental rather than personal consumption.
The SCDOR’s sales tax exemption guidance explains that sellers must maintain resale certificates to substantiate qualifying transactions during an audit.
For each relevant customer, organize:
- The completed resale certificate
- Customer and business identification information
- Applicable retail license information
- Related sales invoices
- Records connecting the certificate to the transactions
Consider a York County wholesale supplier selling merchandise to local retailers.
The supplier should be able to distinguish qualifying resale transactions from ordinary retail sales and provide records supporting the different tax treatment.
Under S.C. Code § 12-36-2540, businesses making both wholesale and retail sales must maintain separate records. Without that separation, the law treats all sales as retail sales.
Review Other Claimed Exemptions
Not every exemption relies on a resale certificate.
South Carolina also uses Form ST-8 for certain exemption claims, while other exclusions or exemptions may have different documentation requirements.
Organize each exemption category separately and identify its supporting records.
If certificates are missing, incomplete, or inconsistent with customer information, flag them for review. Do not create backdated documentation or assume a newly obtained certificate automatically resolves an earlier transaction.
Which Purchases May Raise Use Tax Questions?
A South Carolina sales tax audit may also examine purchases on which sales tax was not collected.
Use tax generally applies when qualifying tangible personal property is purchased for use, storage, or consumption in South Carolina and the applicable sales tax has not been paid.
According to the SCDOR’s use tax guidance, businesses making qualifying untaxed purchases from out-of-state sellers may be responsible for reporting and paying use tax.
Gather Purchase Invoices and Payment Records
Relevant documents may include:
- Vendor invoices and receipts
- Purchase orders and accounts payable reports
- Credit card and bank statements
- Online purchasing histories
- Equipment and inventory purchase records
- Documentation showing sales or use tax already paid
- Use tax calculations and filed returns
For example, a Rock Hill business might purchase office furniture from an out-of-state supplier that does not collect South Carolina sales tax.
The purchase could create a use tax obligation depending on the circumstances.
A contractor in Fort Mill might purchase tools or equipment for its own operations rather than for resale. Those purchases may also require review when the vendor did not collect the applicable tax.
Avoid Assuming Every Untaxed Purchase Is Taxable
The absence of sales tax on an invoice does not establish that additional tax is automatically due.
Exemptions, the property’s intended use, and taxes properly paid to another state may affect the result.
An adviser can compare purchase invoices with the applicable rules and determine which transactions require additional explanation.
This is particularly important for businesses that make frequent purchases through online suppliers, distributors, or vendors located outside South Carolina.
What If Documentation Is Missing or Inconsistent?
Missing records can make it harder to support reported sales, exemptions, or use tax calculations.
However, a missing invoice or inconsistent accounting report does not automatically prove that the original return was incorrect.
The underlying transactions still need to be examined.
Reconstruct Information From Available Sources
If an important report cannot be located, businesses may be able to obtain supporting information from:
- Accounting software archives
- Merchant processors
- Banks and financial institutions
- Vendors and suppliers
- Customer transaction histories
- Prior accountants or bookkeepers
Reconstructed records should be clearly identified, with an explanation of how the information was obtained.
Business owners should preserve original data and maintain an accurate record of any corrections.
Create a Record of Unresolved Differences
Suppose a York County business discovers that its annual sales report exceeds the total reported on its monthly sales tax returns.
The owner should not immediately assume that the entire difference represents unpaid taxable sales.
Instead, the company should examine whether the discrepancy involves exempt transactions, refunds, timing differences, accounting classifications, or omitted sales.
A practical discrepancy log can identify the relevant period, amount, possible explanation, supporting documents, and unresolved questions.
If an audit request is unusually broad or records cannot be produced by the stated deadline, the business should promptly discuss its circumstances with the assigned auditor or legal adviser.
Ignoring a request can result in the department proceeding without information that might support the business’s position.
How Does an Audit Differ From Protesting an Assessment?
An audit and a proposed-assessment protest are separate stages of the South Carolina tax process.
During an audit, the SCDOR examines records and determines whether returns comply with applicable tax laws.
The department may ask follow-up questions, review supporting documents, and provide preliminary findings.
A business generally has an opportunity to discuss draft audit findings and supply additional information before the department issues its final audit packet.
Receiving a Proposed Assessment
If the SCDOR determines that additional tax may be owed, it may issue a proposed assessment explaining the adjustments, penalties, interest, and applicable response rights.
A business that disagrees with an SCDOR proposed assessment should examine the notice immediately.
Under South Carolina Code § 12-60-450, taxpayers generally have 90 days from the date of the proposed assessment or division decision to file a written protest.
The SCDOR’s current appeals guidance explains that when the 90th day falls on a weekend or state holiday, the deadline extends to the next business day.
The actual notice should always be reviewed to confirm the governing deadline, applicable procedures, and any special circumstances.
What Should a Written Protest Include?
A protest generally requires:
- Taxpayer identification and contact information
- Identification of the disputed notice and tax periods
- The nature of the disagreement
- Relevant facts supporting the taxpayer’s position
- Applicable legal grounds
- Supporting documentation
The SCDOR permits protests through MyDORWAY, Form C-245, or a qualifying written submission.
A protest is more than simply sending additional invoices. It formally challenges a proposed assessment through the applicable administrative process.
Businesses should also be cautious before signing agreements or waivers. For example, the SCDOR explains that signing Form SC-870 signifies agreement with the stated liability and waives further appeal rights concerning that matter.
Such documents warrant careful review before signing.
When Should a Rock Hill Business Seek Legal Review?
Not every accounting question requires legal representation. However, certain audit issues can have consequences beyond routine bookkeeping.
Business owners in Rock Hill, Fort Mill, Tega Cay, and surrounding York County communities should consider legal review when:
- The SCDOR questions substantial sales or exemption amounts.
- Multiple reporting periods contain unexplained discrepancies.
- A proposed assessment includes significant penalties or interest.
- The department disputes the business’s interpretation of tax law.
- An assessment protest deadline is approaching.
- The business receives a request to sign a waiver or agreement affecting its rights.
An accountant can help reconstruct transactions and reconcile financial reports. A tax attorney can evaluate disputed legal questions, review assessment procedures, and represent the business in qualifying administrative disputes.
At Ligon Business & Estate Law, we help South Carolina business owners understand the legal implications of tax notices and determine appropriate responses based on the documentation available.
Early review can also help distinguish an accounting correction from a disagreement requiring formal legal action.
FAQs
Which Records Can SCDOR Request in a Sales Tax Audit?
The SCDOR may request records relevant to determining tax liability, including filed returns, sales reports, invoices, purchase records, exemption certificates, and accounting information. The particular documents depend on the audit’s scope and the transactions being examined.
Why Do Exemption Certificates Matter?
Exemption and resale certificates help establish why sales were treated as exempt from tax. In qualifying circumstances, properly completed certificates support the seller’s decision not to collect sales tax. Missing or invalid documentation can expose the claimed treatment to challenge.
Can Purchase Invoices Affect Use Tax?
Yes. Purchase invoices may show whether sales tax was collected, where property was purchased, and whether the transaction requires additional use tax review. Supporting records can also help establish whether an exemption or credit is applicable.
What If Business Records Disagree With Filed Returns?
Businesses should reconcile the differences and preserve the original records. Refunds, timing adjustments, accounting errors, and omitted transactions may explain discrepancies. Any proposed correction should be supported by documentation rather than unsupported changes to historical reports.
How Do I Find the Deadline on a Proposed Assessment?
Review the notice date, protest instructions, and any identified deadline. South Carolina generally provides 90 days from the proposed assessment or division decision for a written protest. Because the applicable procedure and timing are critical, have the specific notice reviewed promptly.
