Guide: 1099 & W-9
Understand the differences between Sandbox and Production environments for Avalara 1099 & W-9, including their purposes, credentials, and features.
Avalara provides 2 different environments for Avalara 1099 & W-9: Sandbox and Production. Each environment is separate, and each has its own credentials. If you have a Sandbox account, you cannot use that account to log on to Production and vice versa.
Tip
When you receive credentials for Avalara 1099 & W-9, you’ll want to record the account number, name, and type. We keep Sandbox and Production credentials separate so you can test your software in Sandbox without accidentally affecting production data.
Consider sharing your Sandbox credentials with developers and reserve Production credentials for accountants. Keeping accounts separate helps avoid the risk of reporting test data to a tax authority.
