PortlandWinair Co extends open account privileges to all qualified applicants in accordance with, and in support of, the Equal Credit Opportunity Act and the Fair Credit Reporting Act. The ECOA prohibits Portland Winair from discriminating against applicants on the basis of race, color, religion, national origin, sex, marital status, age (the applicant must have the capacity to enter into a binding contract), because all or part of the applicant’s income derives from any public assistance program, or because the applicant has, in good faith, exercised any right under the Consumer Credit Protection Act.

What is Portland Winair’s Sales Tax Policy?

Under the law as a wholesale distributor, it is our responsibility to collect sales and use taxes. It is understood that a Portland Winair customer may be exempt from paying sales and use taxes, or that they may be allowed to pay these taxes directly to the appropriate jurisdiction. For Portland Winair not to bill and collect appropriate taxes, we must have a valid exemption certificate on file.

If you have a valid blanket type sales and use tax exemption, or you pay state or local government taxes directly to them, please supply a copy of the certificate to us to avoid any billing issue. If you do work for a tax exempt organization and that exemption can be passed on to you for transactions, you must have a valid exemption certificate, also specifically worded for that purpose. Please provide that certificate to Portland Winair at the time you place an order.

Please be aware that if your bill does not include taxes and then we determine that we do not have a valid certificate, Portland Winair must bill the appropriate sales or use tax retroactively.

Note: A license to collect sales tax is not the same thing as a tax exemption. Any valid certificate will contain words like, or similar to, “exemption,” “exempt,” “for re-sale,” “pay directly to,” or “non-taxable.” If you have any questions concerning your taxable status, please contact your state or local taxing authority.
