Announcing the Check MCP Server
We're releasing two new ways for AI agents to interact with our platform:
- The Check MCP server, which enables AI assistants like Claude, Codex, and Gemini to use Check's payroll APIs through the Model Context Protocol.
- The Check CLI, a command-line interface that allows developers and AI agents to manage payroll operations programmatically from the terminal.
Both of these beta tools can be cloned from our public GitHub repository and used today with any Check platform API key.
Both beta tools ship with full support for over 260 API operations, including list, filter, retrieve, create, update, and delete (where applicable) across all Check API objects. The MCP and CLI also support fine-grained tool filtering, configurable via environment variables or HTTP headers, as well as the ability to run in read-only mode.
These tools can be used to pull custom reports, load historical data into Check’s system for companies that are switching from a prior payroll provider, answer support questions about topics from tax applicability to employee and tax payment timing, and more.
For more information on how to get this set up, please see our API docs.

Filing Close Dates & Delayed Filing Billing
Changelog
3/12/26
Filing Close Dates & Delayed Filing Billing
We are introducing filing close dates to provide a clear boundary for when delayed filing billing applies.
Moving forward, Check will own responsibility for on-time filing if the company filing is unblocked at least 8 business days before the filing due date. After that day, Check will process all unblocked companies and close the filing. This will populate a closed_at date on the Tax Filing API and Console page.
Any company filing processed after the filing is closed will appear as a delayed_filing in the Usage API and on your invoice. This replaces the previous logic for delayed_filing or refile_attempt .
To avoid delayed filing charges, resolve company filing blockers prior to 8 business days before the filing due date.
Reminder: delayed_filing billing will not begin until April 1, 2026.

Usage API: Payee Details on Failed Payment Records
Changelog
3/12/26
Usage API: Payee Details on Failed Payment Records
Usage records for payee_failed_payment now include a resource_information field that identifies the employee or contractor associated with the charge.
resource_information.payee— the employee or contractor IDresource_information.payee_type—"employee"or"contractor"
This lets you attribute failed payment charges to specific workers without additional API calls, making it easier to generate clear, itemized bills for your customers.
For all other usage categories, resource_information returns {}. This is a non-breaking, additive change. See the Usage API docs for full details.
