Sales tax on electrical work in South Dakota
Does an electrician in South Dakota charge sales tax on electrical work?
Most electrical work is excise-taxed, not sales-taxed
An electrician usually charges no sales tax at all. Work that builds, installs, repairs or remodels a fixture to real property is a construction service, and South Dakota taxes construction services and realty improvements with the 2% contractor's excise tax instead of sales tax.
The excise tax lands on the prime contractor's gross receipts, and those receipts include the tax collected from the customer. So the 2% is inside your contract price, not added on the invoice the way sales tax is.
That single fact separates electrical work from most of the trades on this site. A salon or a food truck charges the 4.2% state rate on the receipt. An electrician wiring a building reports on a different return entirely.

The utility carve-out and how it reaches subs
Electrical work for utility companies runs under a different chapter. Contracts for realty improvements with electric, heating, power, water and gas companies, railroads, rural electric cooperatives and telephone companies are taxed under SDCL 10-46B, which reaches prime and subcontractors both, instead of 10-46A.
The prime's contract decides what the subs owe. If the prime's contract is a qualified utility project, the subcontractors' contracts are taxed under the same chapter, change orders included.
For a small electrical outfit, the practical rule is to ask whose property the work sits on before you bid. The same panel upgrade can fall under either chapter depending on the customer, and the license you need is the contractor's excise license either way.

Materials, supplies and the prime's certificates
The excise tax does not exempt what you buy. Materials, supplies and services purchased for an excise-taxed contract are subject to sales or use tax, and the prime contractor owes use tax on owner-furnished materials if no sales or use tax was already paid on them.
The prime issues prime contractor exemption certificates to subcontractors, and cannot deduct amounts paid to subcontractors when figuring excise-taxable gross receipts. Owner-furnished material is included in the prime's gross receipts at its value.
That flows both ways. If you are the sub on a job, the exemption certificate you receive from the prime is a document to keep with the contract, for the same three-year record habit that the filing guide covers for exemption certificates.

When an electrician does owe sales tax
Repair work on real property is still construction services for licensing. But an electrician's receipts can still carry the 4.2% state rate plus municipal tax when the work is a service sold apart from any realty improvement contract.
A retailer who sells, rents or leases products or services in South Dakota needs a sales tax license, and many trades carry both licenses because the two taxes split by job, not by business. Landscaping works the same split, which the landscaping page sets out beside this one.
The example the Department itself gives cuts the other way: a business owner who regularly hires someone to repair and improve their own property is not a prime contractor and needs no contractor's excise license, but the repair person owes the excise tax on the realty improvements done. Whose side of that sentence you sit on decides the license.

Putting the split into your bids
When preparing a bid on excise-taxed work, the Department publishes a factor of 2.041% to compute the excise tax due, while the return itself uses the straight 2% rate. That factor exists because the tax sits inside gross receipts rather than on top of a price.
License first, then bid. The contractor's excise license costs nothing, but starting work without it is the misdemeanor the license guide describes, and contractors must be licensed regardless of the size of their receipts.
For the full rate stack an electrical business can meet, including the 4.2% on any retail side of the shop, see the rates page. And if the business behind the trade is not yet formed, the filing that creates it is covered on the formation services page.

Questions
Do I add 2% to the invoice like sales tax?
No. The contractor's excise tax is on your gross receipts and those receipts include the tax collected from the consumer, so the 2% sits inside the contract price. When bidding, use the 2.041% factor the Department publishes to cover it.
Do I need a sales tax license as well as an excise license?
If all your work is construction services and realty improvements, the contractor's excise license covers it. The moment you sell products or services apart from those contracts, the retail side needs a sales tax license. Many trades carry both.
What if the property owner supplies the materials?
Owner-furnished material is included in your gross receipts subject to the contractor's excise tax, and you owe state and applicable municipal use tax on it if sales or use tax was not previously paid and documented.
Does my apprentice crew change any of this?
Not the tax. The excise tax falls on the prime contractor's gross receipts whoever does the labor, and the license requirement applies to sole proprietorships, partnerships and corporations alike.
