A South Carolina voluntary disclosure agreement (VDA) is an arrangement with the South Carolina Department of Revenue (SCDOR) that lets an eligible, unregistered business disclose unpaid South Carolina tax, file the required returns for an agreed lookback period, and pay the tax and interest. Under the program, SCDOR waives qualifying late-filing and late-payment penalties. Interest is still due, and approval depends on the business meeting the program’s conditions.
For ecommerce and cross-border sellers, the key is to establish whether South Carolina activity created a filing obligation and whether the business remains eligible to come forward voluntarily. South Carolina sales tax administration also has details that can complicate past filings: counties may impose local option taxes, while certain qualifying large purchases are subject to a maximum tax instead of ordinary sales tax treatment. A VDA request is made to SCDOR, not through MyDORWAY; MyDORWAY is the state’s online system for registration, filing, and payment after the appropriate steps are agreed.
What is South Carolina’s voluntary disclosure program?
SCDOR’s Voluntary Disclosure Program is for taxpayers that may have South Carolina nexus—a business connection that creates a tax filing obligation—but have not registered with the Department to collect or remit the relevant tax. The business or its representative initiates contact and asks SCDOR to consider a voluntary disclosure. If accepted, the business reports and pays the tax and interest for the agreed period and receives a waiver of qualifying late-filing and late-payment penalties.
A VDA is not an amnesty that erases the underlying tax. The agreement sets the period and compliance steps, and the business must meet them. SCDOR’s published procedure also requires the taxpayer to register as applicable, file and pay for the agreed lookback period, continue filing and paying for later periods, and waive refund claims or returns for periods before the lookback period. Review the proposed agreement carefully before accepting it.
Who qualifies for a South Carolina tax voluntary disclosure agreement?
SCDOR’s published qualifications generally require that the business not be registered or filing for the tax at issue, not have been previously contacted by SCDOR about that tax, and have no outstanding tax liabilities other than those being reported through the disclosure. The program is intended for unregistered taxpayers that come forward on their own initiative. SCDOR also states a minimum tax liability for the lookback period; confirm the current requirement directly with the Department before applying.
Eligibility is tax-specific and depends on the facts, including the business’s activities, prior filings, and any communications from SCDOR. Do not assume that a business qualifies simply because it has not received an audit notice. If the business has registered, filed, received a notice, or has other unpaid South Carolina liabilities, ask SCDOR or a qualified compliance adviser to assess eligibility before submitting a request.
Can a business apply for a South Carolina VDA anonymously?
Yes. SCDOR’s Voluntary Disclosure Agreement Request form allows the taxpayer or its representative to make a request on a named or unnamed basis. An unnamed request can let the Department review the relevant facts before the business identifies itself, but it does not remove the need to provide enough information for SCDOR to evaluate the request.
If SCDOR accepts the request, the business will need to identify itself and complete the agreed registration, return, and payment steps. Anonymity at the request stage is not a promise of acceptance or a substitute for full disclosure once required. A representative can submit the request, but the business remains responsible for the accuracy of the information and for carrying out the agreement.
What taxes can a South Carolina VDA cover?
The program is for South Carolina taxes administered by SCDOR where the business has a filing or remittance obligation and has not registered for the tax at issue. For sellers, that may include Sales and Use Tax, including applicable local sales taxes. SCDOR’s program is not limited to sales tax; the relevant tax depends on the business’s activities and the tax accounts involved. Confirm with SCDOR which tax types can be included in the proposed agreement.
South Carolina’s sales tax details matter when reconstructing liability. The state has a statewide Sales and Use Tax, and counties and municipalities may impose additional local taxes subject to their own rules. Certain qualifying items are instead subject to a maximum tax; for example, SCDOR describes qualifying vehicles and other listed items as subject to a 5% tax capped at $500 per item, with local taxes not applying to sales subject to that maximum-tax provision. Do not apply that treatment to every vehicle or large purchase: confirm the item’s classification and current rules with SCDOR.
What is the lookback period for a South Carolina VDA?
SCDOR’s published procedure generally uses the three immediately preceding ended tax years for annual filers when nexus existed during that period. For monthly filers, the general period is the 36 immediately preceding ended months; for quarterly filers, it is the 12 immediately preceding ended quarters. If the business had nexus for less time, the period is generally limited to the ended years or corresponding periods in which nexus existed.
The exact period can depend on the filing frequency, when the request is initiated, when returns become due, and the facts of the case. SCDOR’s procedure allows for a shorter period in certain circumstances where nexus is uncertain, and it may extend the period to include later returns that become due before approval. These are not automatic adjustments. Have SCDOR confirm the applicable period in the agreement before preparing returns or calculating payment.
Does South Carolina waive penalties and interest?
For an approved voluntary disclosure, SCDOR’s published procedure provides for waiver of penalties resulting from late filing and late payment, such as failure-to-file and failure-to-pay penalties, when the taxpayer meets the agreement’s conditions. This is a penalty waiver, not a waiver of the tax itself. The business must file the required returns and pay the tax for the agreed period.
Interest remains payable under South Carolina law. The amount depends on the tax, periods, and applicable rules, so do not estimate it using an assumed rate. The agreement and SCDOR’s payment instructions should establish what is due and when. A VDA does not guarantee that every charge will be waived; confirm the treatment of the specific liabilities with SCDOR.
How do I apply for a South Carolina voluntary disclosure agreement?
Start by reviewing the current Voluntary Disclosure Agreement Request form, SCDOR form NX-6, and the Department’s voluntary disclosure instructions. The request can be submitted by the business or its representative, on a named or unnamed basis. SCDOR directs applicants to email the completed request to SCVDA@dor.sc.gov or mail it to the Nexus/Discovery Section at the address shown on the current form. Use the current form and verify submission details on SCDOR’s website before sending anything.
Provide complete, accurate information about the business, its South Carolina activities, the tax types involved, the periods at issue, and any relevant prior registrations, filings, or contact with the Department. SCDOR says incomplete applications cannot be processed. Wait for SCDOR to respond about voluntary-filer status and the proposed agreement; do not treat submission alone as approval. If accepted, review the lookback period, covered taxes, deadlines, and required filings before agreeing.
What records, returns, and payments will you need?
Prepare records that let you identify South Carolina sales and purchases by period and determine the correct tax treatment. For an ecommerce seller, useful records commonly include sales and order data, invoices, customer delivery addresses, refunds and credits, marketplace and direct-channel sales, exemption documentation, and records of tax collected. Keep supporting accounting and payment records as well. The exact documents SCDOR requests depend on the tax and the business’s facts.
After acceptance, SCDOR’s current program page says the taxpayer has 60 days from the date of acceptance to submit all requested documents. The agreement or Department instructions control what must be filed and paid and by when. Returns should reflect the applicable state and local treatment, including any relevant maximum-tax items. Do not assume that a single sales total is enough to prepare accurate returns; reconcile transaction-level records and ask SCDOR or a compliance professional to resolve uncertain classifications.
What happens after approval—and what if SCDOR has contacted you?
Once the agreement is accepted, follow its instructions to register as required, submit the requested records and returns, and pay the tax and interest for the agreed period. SCDOR’s program page gives 60 days from acceptance for requested documentation, but follow the specific agreement and confirm any deadline that applies to your case. For ongoing compliance, use MyDORWAY, SCDOR’s online tax portal, to manage applicable registrations, returns, and payments. Continue filing and paying for periods after the lookback period as required.
A business generally cannot qualify for voluntary-filer status for a tax if SCDOR has already contacted it about that tax. The Department’s published qualifications also exclude businesses that are registered or filing for the tax at issue. If SCDOR has contacted the business, do not assume a VDA remains available or ignore the notice; respond as instructed and ask SCDOR whether any voluntary disclosure option applies to the circumstances. The consequences of contact depend on what the Department sent and the tax involved.

South Carolina sales tax distinctions that can affect a seller’s VDA calculations
| Transaction or tax feature | South Carolina treatment to check |
|---|---|
| Ordinary taxable retail sale | The statewide Sales and Use Tax applies to taxable sales; determine whether the destination also has an applicable local tax. |
| County or municipal local tax | Counties and municipalities may impose additional local taxes. The applicable tax and its restrictions depend on the jurisdiction and transaction. |
| Qualifying maximum-tax item | Certain listed items, including qualifying vehicles, are subject to a maximum-tax provision rather than ordinary treatment; SCDOR describes a 5% rate capped at $500 per item, and local taxes do not apply when the maximum-tax provision governs. |
| Unprepared food | SCDOR states that unprepared food is exempt from the state Sales and Use Tax, but local taxes may still apply unless the local tax specifically exempts it. |
| Sales tax administration | Retailers report and pay applicable local sales taxes with the state Sales Tax return; MyDORWAY is SCDOR’s online portal for tax registration, filing, and payment. |

SCDOR’s general procedure uses three immediately preceding ended tax years for annual filers, 36 ended months for monthly filers, or 12 ended quarters for quarterly filers, limited as applicable by how long nexus existed. The period can vary with the facts and timing, so rely on the period stated in the agreement rather than assuming a fixed result.
