South Dakota QuickBooks cleanup: the sales-tax setup, fixed at the source.
In South Dakota the QuickBooks errors that cost money are sales-tax errors: services set as non-taxable, city tax booked to the state line, and a contractor’s excise tax nobody accrued. We find them, correct them, and tie the liability to what was filed, in your own QuickBooks file, on a written fixed-fee scope.
A South Dakota QuickBooks cleanup corrects the sales-tax setup first: service items that should be taxable, municipal tax recorded against the right city, the liability reconciled to each return, and, for construction businesses, the 2% contractor’s excise tax on gross receipts from construction work. Then every account is reconciled and the file handed back with a written summary of each correction. TechBrot does not file returns.

Why South Dakota files drift.
A service item marked non-taxable, as it would be in a state that does not tax services, quietly under-collects in South Dakota for months, until a filing, an audit letter or a new bookkeeper catches it.
The second drift is municipal: with state and city tax on one return, a file that lumps them together cannot produce the city breakdown the return needs — and a contractor that never set up the excise tax account has a liability the books do not show.
Three South Dakota rules the cleanup checks.
From the Department of Revenue’s and Legislature’s own pages, read September 28, 2026.
Sales tax on services
Sales tax applies to “the sale of services” as well as goods, at 4.2% today (4.5% from July 1, 2027 under SDCL 10-45-2).
One return, state and municipal
The Department of Revenue administers municipal sales tax; “Only one tax return is needed.”
Contractor’s excise tax
A 2% excise tax applies to gross receipts from construction work, separate from sales tax.

What a South Dakota cleanup turns up.
Service sales never taxed
Items set to non-taxable, so tax was never charged and the liability is understated.
City tax booked to the state line
One liability account for everything, so the return’s municipal breakdown has to be rebuilt by hand.
No excise tax account
Construction receipts with no contractor’s excise tax accrued.
State withholding that should not exist
A state income-tax item set up in payroll for a state with no income tax.
Sales tax first, then everything else.
Map sales and locations

What it costs, and where to go next.
QuickBooks cleanup is published at $1,200–$15,000+, fixed fee against a written scope; a sales-tax-only fix can be a focused cleanup ($1,200–$3,000). Whether past under-collection needs to be reported is a question for your tax professional; we give them the numbers.
