Introducing the Finch Documents API (beta), a completely new employment data endpoint beginning with support for W-4 documents.

We’re thrilled to announce the beta launch of the Finch Documents API, a completely new employment data endpoint, beginning with support for W-4 federal tax withholding forms. This milestone brings a first-of-its-kind programmatic approach to accessing and standardizing the data from employer and employee tax documents. 

By automating the delivery of W-4 data from employers’ payroll systems to end applications, this new API unlocks use cases across health benefits, retirement, tax and accounting, lending, and so much more. Finch Documents represents a major step toward democratizing access to data across the entire employment ecosystem. 

Our solution not only centralizes access to these documents, but leverages cutting-edge, machine-learning-based document parsing to standardize filing statuses and withholding details across platforms.

The challenges of accessing W-4 data (and other documents)

W-4 documents hold critical data needed for a wealth of employment functions — information like an individual’s marital or filing status, whether they have any dependents, and their withholding details. 

But accessing that data presents a challenge. Either the employer has to extract the details from paper or digital documents and collect them in a single repository, like a spreadsheet, to send to their providers; or they might send the full W-4 documents to the provider for data extraction. Either way, this process is typically manual, introducing the potential for human error and adding unnecessary complexity for both the employer and the provider. 

Providers that work with this sensitive employee information — including employer-sponsored benefits providers, insurance underwriters, lenders, and tax and accounting applications — need a cleaner, automated way to pull this data directly from the source: the employer’s payroll system.

How Finch Documents Works

Our Documents API integrates seamlessly into Finch’s ecosystem, maintaining the simplicity you’ve come to expect. W-4 data is pulled directly from the documents in the employer’s payroll system and delivered to your application in a standardized format.

Finch Documents consists of a few simple endpoints under /employer/documents, allowing users to retrieve all documents from an employer or only those for specific individuals. 

Here’s how it works:

  1. Invite employers: Invite employers to connect their HRIS or payroll system with Finch. Finch Connect can be embedded into  your application or sent via a secure link, generated in the Finch Dashboard. 
  2. Connect providers: Employers can then go through the Finch Connect process to authenticate the connection between your application and their system of record. Finch walks them through any nuances between providers.
  3. Receive data: Finch retrieves the document, then uses machine-learning-based data parsing to extract the information and deliver it to your application in our standardized format.
Three screenshots show the Finch Connect workflow, in which employers authenticate the connection between a provider and their payroll or HRIS system.
Our built-in onboarding tool, Finch Connect, makes it easy for employers to authenticate a connection between their payroll or HRIS provider and your app.
