I purchased a steel building from a company in Oregon six years ago. I signed a contract paid thte amount requested. I asked why no sales tax was collected and was told Oregon does not collect it and we only manufacture the building for you we do not deliver the building. An independant shipping company will deliver the building. When the fabrication was complete the shipper delivered the building and I paid the shipper his fee plus 8% tax on the shipping fee. Fast forward six years, yesterday I get a letter from the fabrication company, the state of Washington wants to collect sales taxes on all buildings the oregaon company fabricated for Washington state for the past 12 years. The company is requesting I send the state of Washington another $1300 within 30 days. Who is liable for the sales tax at this point. I feel I did my due diligence to address this issue when I signed the cantract and again when I made my final payment. If additional tax is required the responsibility is with the fabrication company to pay.

Optional Information:
Country relating to Question: United States
State (if USA): Oregon
What have you tried so far?: nothing just got the letter requesting I pay sales tax now on a purchase I completed six years ago.
