If your marketplace will calculate, collect, and pay tax for sellers in all jurisdictions where you operate, then follow these steps for setting up your company.

The Avalara Knowledge Center provides detailed information about how to set up a company, including the information you need to collect, adding your company information, and specifying where you’ll collect taxes.

For the purposes of this integration guide, we'll walk through the setup process for creating a company in your Sandbox environment. Technology partners can create a test company with generic information; API customers may want to use their actual company information.

Sign in to your Avalara Sandbox environment.

Check your email for the confirmation that you received from Avalara when you signed up for your account.

Sign in to your account using the username and link in your confirmation email.

Follow the prompts to create a new password.

Select I accept to the Terms and Conditions.

Select Get started to begin the walk through for adding a company. The first step is to specify a name and taxpayer ID for the company, and then click Next. This information isn’t verified, so technology partners can specify a generic name and taxpayer ID.

Enter a mailing address for your company. Validate the address, and then select Next.

Once you've validated your company's primary address, AvaTax enables tax collection in that jurisdiction. The next step is to add more regions where this company will collect tax. Click Yes, add more US regions, then choose Select from a list.

For the purposes of this integration guide, we recommend that technology partners enable jurisdictions in locations where they’ll perform test transactions. To run the test transactions included in this guide, enable tax collection in:
- Washington state
- District of Columbia
Select Add selected regions

For regions where a sales and/or use tax could apply, AvaTax prompts to specify the type of tax to collect. For technology partners and for the sake of testing, select Sales or sellers use tax. For merchants and API customers, the tax type you select should match the tax return you need to file. Select Next.

When prompted to confirm whether this company is registered to collect and pay tax in other countries, make your selection based on the scope of your integration. Select No, where I collect tax is complete.

A confirmation page opens. Select Done with tax jurisdictions.

Finally, click Activate company to begin using AvaTax.

The marketplace collects and pays everywhere
