In most states pure labor is not taxable. For instance your truck mechanic tightens your
fan belt. No tax. If he adds so much as a pint of oil to the crankcase at the same time then
the ENTIRE job is a taxable event.
Anyone who believes they can use subtotals and avoid the labor taxes on the total invoice
had best pray they don't get a state audit.
I just had a major go-round with my state's sales tax folks. They almost put me out of business
as they froze my bank account and only because I failed to respond to them. I failed to respond
because all the crap they sent went to an address I have never heard of, never visited and
that was strange because we have been at the same addy and filing from the same addy for well
over 30 years (office addy, not shop).
Anyway, after clearing up the matter my lawyer left and I was chatting with one of the specialists.
Learned something new. If I build a sign be it pylon or wall attachment or even letter a store front
window, I am not supposed to charge tax as that is an improvement to commercial property
and that will be covered by property tax. Put the same vinyl legend on the rear window of
that same business's truck and it is a taxable event. I talked to 4 other sign shops about their
practice - they, like me, have always charged for all their work except resale.
Who knew???
