Which Washington State filing Calendar should I choose?


I am trying to set up the filing Calendar for the state of Washington. 

There are 2 forms present. 

The WA B&O combined Excise Tax monthly excise tax form for companies 
participating in Streamlined Sales Tax only! And WA Multipurpose Combined 
Excise tax return for non-streamlined sales tax customers. 

Which one do I need to choose?

  • The correct form to pick depends on whether you are registered to participate in the Streamlined Sales Tax (SST) agreement.
  • If you are SST registered you would need the WA B&O Combined Excise Tax
  • If you are not SST registered you would need the WA MultiPurpose Sales
