Insurance

5How much electrical contractor insurance do you need in South Carolina? What is this?

What South Carolina requires you to carry before you work.

Minimum liability insurance	Not listed yet
Type of policy	None found. Neither Chapter 11, Chapter 59 nor the board regulations read for this record set a liability insurance minimum for electricians
Who this applies to	Not applicable at state level. Cities, general contractors and customers usually ask for a certificate anyway
Who must be named on the certificate	None found
Workers' comp required?	Only once you cross both thresholds. You need cover when you regularly have four or more employees and your total payroll in the previous calendar year was $3,000 or more. Part-time workers and family members count toward the four
Who can opt out	Either threshold on its own exempts you. Fewer than four employees, or a payroll under $3,000 last year, and you are outside the law. You need both before cover is required. A sole proprietor or partner may choose to be covered as an employee and must tell the insurer. If you hire a subcontractor, you are treated as the employer of the subcontractor's injured workers if the subcontractor has no coverage (42-1-400 and 42-1-410)

Tax

9Does an electrician charge sales tax on labor in South Carolina? What is this?

In South Carolina, no sales tax on your labor or on your bill to the customer for an electrical job, because the tax was paid when you bought the materials. The rest of the rules are below.

See how this compares in every state: Can you charge sales tax on labor? The rule in 25 states

Rule for contractors	You are the final consumer of everything you install. You pay sales or use tax when you buy pipe, fittings, water heaters, electrical supplies and electrical fixtures. The regulation lists electrical supplies and electrical fixtures by name as building materials
Labor	No sales tax on your labor or on your bill to the customer for a electrical job, because the tax was paid when you bought the materials
Homes versus businesses	Same rule for homes and businesses. South Carolina does not tax contractor labor in either
Labor on new buildings	No sales tax
Selling and installing as two prices	If you run a showroom or sell fixtures to people who install them elsewhere, you are a retailer for those sales. You buy for resale tax-free and charge the customer tax on the sale price. Installation is not taxed if it is a separate, reasonable line on the bill
One-off sales	Selling a spare part to a customer now and then is an isolated sale and is not taxed, as long as you paid tax on it when you bought it
Buying from out of state	Materials bought in another state and used in South Carolina owe South Carolina use tax, with a credit for tax paid to the other state
Tax rate	6 percent state, plus local taxes collected by county. Local use tax is owed by the contractor where the materials are first used

Getting paid

10Getting paid: lien and notice deadlines for a South Carolina electrician What is this?

If you are not paid in South Carolina, a lien on the property is your backstop, but only if your notice goes out on time: no fixed deadline for a preliminary notice. The lien itself must be served on the owner within 90 days of your last day on the job (last day March 1 means serve and file by May 30).

The order things have to happen in, counted in days

Day 0
Your first day on the job
The clock starts here.
Day 90
Send your notice
No fixed deadline for a preliminary notice. The lien itself must be served on the owner within 90 days of your last day on the job (last day March 1 means serve and file by May 30)
Day 90
File your lien
File the lien statement with the county register of deeds or clerk of court, and serve it on the owner, within 90 days after you last did work or supplied materials (last day March 1 means by May 30). Then sue to enforce it within six months of that last day or the lien is dissolved

Each day count is counted from the day the rule beside it names, which is not always the same day. Read the sentence under each one.

Who has to send a notice	Contractors hired by the owner do not send a preliminary notice. Subcontractors hired by the contractor do not either. Only a sub-subcontractor, or a supplier to a subcontractor, must send a Notice of Furnishing by certified mail to the contractor. That applies only if the owner filed a Notice of Project Commencement with the county within 15 days of the job starting. Without that notice, the sub-subcontractor's lien is capped at what the contractor still owes the subcontractor
Send your notice by	No fixed deadline for a preliminary notice. The lien itself must be served on the owner within 90 days of your last day on the job (last day March 1 means serve and file by May 30)
File your lien by	File the lien statement with the county register of deeds or clerk of court, and serve it on the owner, within 90 days after you last did work or supplied materials (last day March 1 means by May 30). Then sue to enforce it within six months of that last day or the lien is dissolved
What the owner can argue back	Your lien can never exceed what the owner still owes on the contract. If the owner already paid the contractor in full, there may be nothing left to lien

Watch out

12What catches people out in South Carolina What is this?

The things people get wrong or do not expect about South Carolina, in a few sentences.

South Carolina files electrical under mechanical contracting, alongside air conditioning, heating and plumbing. There is no separate electrical board.
The statute draws the line at voltage. The electrical classification covers work under 600 volts. Above that, check with the board before you bid.
Two boards, two thresholds. Commercial and larger work over $10,000 goes to the Contractor's Licensing Board. Residential work over $500 goes to the Residential Builders Commission instead.
Your license carries a money ceiling. Group One stops at $35,000 a job and Group Five has no limit, and which group you get depends on a financial statement, not on your skill.
There is no common renewal date. Your own license carries its date, and the board renews in two-year blocks.
Workers' comp starts at four employees, and there is a second test. A payroll under $3,000 last year also keeps you out, and either one on its own is enough.
