South Carolina business tax questions

Potentially. South Carolina law provides criminal penalties when a person willfully fails to file required returns, pay tax, keep records or supply required information: a misdemeanor carrying up to one year in prison and/or a $10,000 fine. Willful tax evasion is a felony carrying up to five years and/or a $10,000 fine per count, and SCDOR does bring these cases. Most delinquent-tax situations are handled through notices, assessments, penalties, interest and collection activity, but prolonged or intentional noncompliance should not be ignored.

SCDOR sends notices and generally asks for the missing returns and payment. If the problem is not resolved it can move to assessments and collection measures. Penalties and interest keep building on unpaid tax until the returns are filed and the balance is paid or covered by an agreement.

Yes. SCDOR runs a voluntary disclosure program for businesses that should have registered or filed and did not. Coming forward through it can lead to penalties being waived. It is aimed particularly at businesses that never registered or never filed.

Moving does not make old South Carolina filing obligations or tax disappear. The old company's obligations depend on when it stopped doing business in South Carolina and when it was formally closed, not on where you live now. A business based elsewhere can also keep South Carolina obligations if it still has property, employees, representatives or sales here. Unpaid South Carolina tax can become a lien on property, and SCDOR can levy wages and bank or investment accounts once there is an unpaid assessment or lien.

Very possibly. SCDOR lists the presence of property such as goods, offices, real estate and vehicles in South Carolina as something that creates income tax nexus, and where you personally live does not change that. For sales and use tax, keeping an office or other place of business here creates physical nexus whether it is permanent or temporary. A desk, computers or servers the company owns are company property in the state; SCDOR's Revenue Ruling 03-4 treats a website on a South Carolina server as a separate case only where the company does not own or lease the server. Nexus is decided tax by tax, and equipment kept here can also be taxable business personal property. If you are not sure, SCDOR's Nexus Questionnaire has it review your facts and tell you which accounts you need. If returns were missed, voluntary disclosure may allow penalties to be waived.

Probably yes, and it helps to split it into three separate questions. First, nexus: SCDOR lists property in South Carolina, including offices and other physical property, as something that creates income tax nexus. Servers and equipment the company owns and keeps here are that kind of property, whatever work they do. Where the public website is hosted matters much less; Revenue Ruling 03-4 treats a website on a South Carolina server as not creating nexus only when the business does not own or lease that server. Second, how much income: having nexus does not mean South Carolina taxes all of the company's income. A business active in more than one state apportions its income, and South Carolina taxes its share (SC Code 12-6-2252 and 12-6-2295). Third, property tax: separately, business furniture, fixtures and equipment kept in South Carolina, such as servers, networking gear, computers, racks and battery backups, are business personal property with their own filing, even if almost nobody works there. What decides the details: which entity owns or leases the office and equipment, what the machines actually do, where customers and revenue are, and whether that entity is registered in South Carolina.

Not automatically. SCDOR normally has 36 months from the filing date to assess tax, but that limit does not apply when a required return was never filed. The separate 10-year limit is on collection, and it runs from when the tax is assessed, not from when the return was due; it can also be extended or suspended. So a return that was never filed ten years ago may still be assessed today.

Sources: SC Code of Laws 12-54-85 (assessment and collection limits)

Yes, once there is an unpaid assessment. Unpaid tax is a lien in favor of SCDOR on property and rights to property, and SCDOR says an unresolved assessment can lead to a state tax lien on real or personal property in South Carolina. It can also levy wages and bank or investment accounts when there is an unpaid assessment or tax lien.

SCDOR offers payment plan agreements to eligible businesses and individuals. A plan does not reduce what is owed; it spreads the payments out.

Penalty waivers can be requested in qualifying circumstances (Form C-530 or through MyDORWAY). Each request is decided on its facts and supporting documents. Interest generally is not waived.

Sources: SCDOR Penalty Waivers

Yes. Qualifying taxpayers can settle certain South Carolina tax debts for less than the full amount when collection is doubtful or there is exceptional economic hardship. There must be at least one assessment of $10,000 or more for a single filing period, not counting penalties, interest and court costs, and it does not apply to sales or withholding tax.

Sources: SCDOR Offer in Compromise (SC656 instructions)

Yes. The appeals process generally allows 90 days from the Regulatory Notice to file a written protest. Protests can cover the tax, a valuation or a classification SCDOR got wrong.

An S corporation generally does not pay the 5% corporate income tax on income that passes through to its shareholders, who report it on their own returns. It still files its SC1120S each year, owes the annual corporate license fee, and can owe tax at the entity level in some situations.

An annual fee of 0.1% of capital stock and paid-in surplus plus $15, with a minimum of $25 a year. It is owed for each year the corporation exists, so delinquent years each carry their own fee.

A property tax on business furniture, fixtures, computers, machinery and equipment. The business reports each asset's original cost, depreciation and net depreciated value; the taxable (assessed) value is 10.5% of the net depreciated value, and the county applies the millage for the taxing districts where the business is located.

Sources: SCDOR Business Personal Property

SCDOR says all businesses are required to file business personal property returns, including businesses that lease equipment located in South Carolina. Depending on the business classification and county, the return goes to SCDOR or is handled with the county.

Sources: SCDOR Business Personal Property

Millage is the property tax rate: one mill is $1 of tax per $1,000 of assessed value. It is the combined rate of the county, municipality, school district, fire district and other districts that cover the business location, so two businesses in the same county can pay different rates, and rates change from year to year.

Only property the business still had should be taxed for a given year. If old records still carry equipment that was sold, scrapped or taken out of service, the value should be corrected, and an assessment built on a wrong value can be protested.

It is SCDOR confirming that the returns and taxes it administers have been filed and paid. The application fee is $60 and an issued letter is valid for 30 days, so it should be requested close to when the reinstatement is filed.

Sources: SCDOR: Request a Certificate of Compliance

The Certificate of Tax Compliance is only issued once returns and taxes SCDOR administers are filed and paid, and all applicable tax accounts generally have to be brought into compliance first. A payment agreement or penalty waiver can change what has to be paid, so ask SCDOR how an agreement affects the certificate in your case.

State-tax attorneys, CPAs, enrolled agents, state and local tax (SALT) specialists, property-tax consultants and tax-resolution firms do this work. Some reinstatement companies handle the paperwork but do not negotiate tax balances, so ask which parts they cover.
