PhD Posters only collects tax in states where we are required to do so. If you're not in one of these states, then you'll never be charged tax, period.
If you represent a university or other institution which is exempt from state sales tax, PhD Posters may process your order without charging tax. Institutions which we recognize as tax exempt are listed below. If your institution is not in the list below, please email firstname.lastname@example.org with a PDF of your exemption certificate, and allow up to a week for verification. We cannot process tax exemptions once an order has been paid for.
To comply with state laws:
Email email@example.com with a PDF of your exemption certificate to be added to this list. (Ask your nearest administrative assistant to get a copy of the certificate.)
