You have registered under the Streamlined Sales Tax (SST) program and would like to know whether you are able to file returns with TrustFile.
TrustFile is unable to support SST filings. There are special requirements in the SST program which limit the ability to file with TrustFile.
Avalara's AvaTax Returns product is capable of filing SST returns. Please contact your account manager or sales rep for further information.
