Avalara, a provider of tax compliance automation software, has launched new APIs for its 1099 & W-9 solution.
These APIs are designed to help companies integrate 1099 and W-9 compliance workflows into their existing business platforms, thereby automating manual and time-consuming processes.
Using the new APIs, businesses can collect W-9 forms from vendors, validate tax IDs against IRS databases, confirm mailing addresses with the US Postal Service, electronically file 1099 forms with the IRS and states, and deliver recipient copies, all from a centralised platform.
The aim is to save time and improve resource allocation by automating the entire compliance process, stated Avalara.
The process begins with a company’s business platform, where Avalara’s APIs can transmit requests for W-9s from vendors and instructions for processing IRS forms.
Custom instructions determine the compliance workflow steps, such as tax ID matching with the IRS, address validation, and e-filing to states. Avalara’s system then executes these steps, bringing together the business, vendors, and the IRS.

These updates can trigger further actions, such as text alerts or vendor communications.
Key features of the APIs include on-demand system access, a single workflow for streamlined operations, no direct IRS engagement required, and improved accuracy and efficiency through automation.
Avalara general manager of Accelerator Businesses Kevin Halverson said: “Avalara files millions of 1099s with the IRS and state tax authorities each year on behalf of our customers.”
“Our new APIs offer customers increased flexibility to connect with their existing systems to fully automate their W-9 collection and 1099 filing, provide our technology partners with the ability to embed our services within their own offering, and demonstrate our commitment to expansion in the 1099 and W-9 compliance market.”
In April 2025, Avalara was in the news for the appointments of Sydney Carey as its CFO and Karyn Smith as its chief legal officer.
