Please advise if the project is SALES TAX EXEMPT or subject to SALES TAX. Arrow Right Answer: Please see response in questions 6 and 10. All payments to the Contractor will be made by OCAT. OCAT is a Tax Exempt entity. This means that the Contractor cannot charge OCAT sales tax, or any other tax, for the payments made to the Contractor. This Tax Exemption does not extend to the Contractor. This means that the Contractor is obliged to pay the sales tax charged to them by their vendors, suppliers, or other contractors. Another way to say it is that the Contractor must pay sales tax on the purchases they make, but the invoice submitted to OCAT for payment shall not include sales tax or any other tax (payroll tax, etc.). | TAX CLARIFICATION After several questions have been turned in that have not clearly answered the question, we are seeking a clear YES or NO if the job is to be bid with SALES TAX or to be bid without SALES TAX.
