A shop can be busy every day and still not know whether it is making money, because parts, labor, sublet work, shop supplies and sales tax all run through the same repair orders. Auto repair bookkeeping done properly separates them every month, so the numbers tell you what the bays are actually earning.

Parts margin and labor rate: the two numbers that run a shop
Shops that lump all sales into one line cannot see that the parts matrix is too generous, that a supplier has crept prices up, or that the effective labor rate is far below the posted one because of comebacks and unbilled diagnostic time. We report parts gross profit and labor gross profit separately every month. Most owners adjust something within the first quarter.
Sales tax on repair labor in North Carolina
Since 2016 North Carolina has applied sales tax to repair, maintenance and installation services, which includes auto repair labor as well as parts. The rules on what is taxable, how shop supplies are treated and how to report it are specific, and getting them wrong leads to an audit from the Department of Revenue rather than the IRS. We file the returns from the same books we keep, so the sales reported match the sales recorded.
Technician pay
Flat-rate pay is standard in the trade and legal, but it still has to meet federal minimum wage and overtime rules for every workweek, which is where shops get caught. Our payroll service handles flat-rate, hourly and hybrid plans, posts the labor cost to the right place in the books, and files the payroll taxes so a notice never shows up.
Equipment, deductions and the year-end return
A new lift or a diagnostic platform can be expensed in the year of purchase or depreciated over time, and the right choice depends on what the rest of the year looks like. Shop supplies, uniforms, software, training, the shop truck and the usual overhead all belong on the return. Keeping the books through the year is what makes sure they get there. See business tax preparation.
Shops that have fallen behind
Independent shops are owner-run, and when the owner is under a car the paperwork waits. If that has turned into unfiled returns or a notice, James handles IRS resolution as an Enrolled Agent while we get the books current, so the shop keeps running.

Do I charge sales tax on labor in North Carolina?
Yes. Since 2016 North Carolina applies sales tax to repair, maintenance and installation services, including auto repair labor, as well as to parts. Getting the rate and the filing right is part of our bookkeeping for shops.
How do I know if my parts margin is where it should be?
Only by tracking parts revenue and parts cost separately from labor. Shops that lump everything into one sales line cannot see that the parts matrix is too generous or that a supplier has quietly raised prices. We split them so you can.
Can you handle flat-rate technician pay?
Yes. Flat-rate, hourly, and hybrid pay plans are all processed through our payroll service, with overtime handled correctly under federal rules.
What can an auto repair shop deduct?
Equipment such as lifts, scanners and compressors, shop supplies, uniforms, software subscriptions, vehicle expenses for the shop truck, training, and the usual rent, utilities and insurance. Larger equipment is either expensed in the year of purchase or depreciated, whichever serves you better that year.
