Sales tax is on the price, not on the
markup over your costs. OTOH, as a
manufacturer of prints, you wouldn't
have paid any sales tax on materials
or services involved in manufacturing
the finished product.
Ben Dare, Don Dat .... and altho the
simple explanation above is factual in
so far as the general idea, the reality
is so detailed that this forum is the
worst possible place to ask about it.
All the details are available from the
state.
https://www.tax.ny.gov/ But the info is useless to you unless
you are a lawyer or accountant. One
thing you're possibly failing to grasp
is that the tax we pay whenever we
buy something is not just NYS sales
tax. It's a combination of 3 taxes at
3 different rates: state, county, and
city sales taxes.
I hope to have accomplished only 2
things by the above advice. Firstly,
to warn you not to get involved if
your sales are personal and minor.
Secondly, to warned you against
seemingly expert advice that may
be offered here in this huuuugely
inappropriate venue.
Once again ...
https://www.tax.ny.gov/ Best thing to do is just turn your
back on this thread, forget you
ever started it, and never read it.
I assure you, that is what I will
do right now.
