Parts-vs-labor sales tax, seller's permits, and technician payroll for repair businesses that run on service calls.

The first thing most repair businesses get wrong isn't a tax question, it's a sales tax question: parts are taxable in nearly every state, but labor often isn't, and the line between them shows up differently depending on where you operate. California's CDTFA rules, for example, treat repair labor and installation labor differently - get it wrong on enough invoices and it adds up fast at audit time.
You need a seller's permit before you sell your first taxable part, and you need resale or exemption certificates on file for any parts you buy wholesale to resell - without them, your supplier may be required to charge you tax you shouldn't be paying twice.
Technicians running routes out of vans means real mileage and vehicle expense tracking, plus tool and equipment reimbursements that need to be handled consistently, not ad hoc, or they turn into a payroll headache.
Warranty work creates its own receivable: work performed now, paid by a manufacturer or extended warranty company later, sometimes much later. If it's not tracked separately, it distorts your actual collections and cash flow.
Payroll usually mixes hourly techs, commission or per-job bonuses, and sometimes on-call pay - all of which need to be set up correctly from day one, not patched together after a Department of Labor question comes up.
We register and maintain your seller's permit, keep resale and exemption certificates on file, and apply the correct parts-vs-labor sales tax split for the states you operate in.
Parts inventory, technician mileage, tool reimbursements, and warranty receivables get tracked separately so your books reflect what you actually collected versus what's still owed.
Vehicle and equipment purchases, Section 179 on tools and diagnostic equipment, and entity structure reviewed against your actual margins on parts versus labor.
Returns prepared with your sales tax filings reconciled first, so parts sales, exempt labor, and warranty income all match what's reported to the state.
Hourly, commission, and per-job pay structures set up correctly, with mileage and tool reimbursements handled as non-taxable when they qualify.
Route and technician profitability reviews, pricing checks against your real parts-plus-labor cost, and cash flow planning around warranty reimbursement timing.
Most independent repair operators do well as an LLC, moving to an S-corp once profit is steady enough that the payroll tax savings outweigh the extra filing cost. If you're buying a van fleet or hiring your first W-2 technician, that's usually the right moment to revisit the decision.
Explore LLC FormationIn most states you'll charge tax on the part and not on the labor, but the exact rule - and how it needs to appear on the invoice - depends on your state. We'll set up your invoicing so the split is handled correctly by default.
Not if you have a valid resale certificate on file with your supplier. Without one, they're required to charge you tax, and you'd effectively be paying it twice once you resell the part.
Mileage reimbursement and tool allowances can often be structured as non-taxable if they're set up correctly and documented. We'll help you build a reimbursement policy that holds up if it's ever questioned.
As a separate receivable from your regular customer invoices, so your books show the gap between work completed and manufacturer or warranty-company payment, rather than making your cash position look better than it is.
