Will my Washington State Return Include Interstate Sales?


For certain “Washington-based” businesses the state may require you to report and deduct non-Washington sales on your Washington Sales Tax return. You would like to know if interstate sales will automatically be included on your return.


Avalara Returns   



  • By default, Avalara will not report interstate sales in this manner (only Washington Sales will be reported on the return).

  • If you determine that you are subject to interstate reporting requirements for the Washington return, please submit a case to Support so that we can make a note on your return and our filing team can report these sales properly.

NOTE: There is no tax difference between either filing method and Washington tax is reported the same in both scenarios.
