1099 & W-9 Software for Accounting Firms

Trusted by some of the largest 1099 compliance practices in the U.S.

How it works

Manage 1099 and W-9 compliance for many clients at once

Create just one account with Avalara 1099 & W-9 for all of your clients.
Manage each of your clients’ IRS forms in a central location where it’s easy to toggle from one view to another or all in one view for simplicity.
Finally, deliver copies of each of your clients’ filings directly from the application.

Easy administration

Avalara 1099 & W‑9 lets administrators control which teams can view certain clients, keeping workspaces clean and organized. This matters for accounting practices that need multiple teams to manage different client portfolios. In some cases, client contracts prevent sharing information between partners in the same firm.

Strict security protocols

Accounting firms must handle sensitive client data, like Social Security numbers, when filing 1099s. This responsibility creates security risks — even small tasks like collecting and filing forms can lead to exposure. Automating the process with a secure e-filing solution is a safer option. Avalara 1099 & W‑9 has achieved SOC 2 Type 2 compliance, helping reduce errors and protect your vendor data.

Powerful accounting system integrations

Accounting practices can connect popular accounts payable systems — like QuickBooks Online, Xero, and Bill.com — to Avalara 1099 & W‑9 to work more efficiently, reduce errors, and keep client data secure and off local devices.

Staying ahead of 1099 and W-9 compliance in changing times
