With the release of v2026-02-01—which is stabilized as of today, April 1 2026—v2025-11-15 entered the year-longdeprecation process effective February 1 2026, and will move through these deprecation phases:
On the 1st business day of each month, we communicate the upcoming changes to partner notifications, as well as partner notifications that are now deprecated. You have until the end of that notice’s month (i.e. the “effective at” date) to make necessary updates.
We have deprecated new_ein_issued, as previously messaged .
We're launching the Gusto Embedded Dev Assistant MCP server into Open Beta. AI-powered development tools can now connect directly to Gusto's API reference and documentation, giving your AI assistant accurate, up-to-date context instead of relying on stale LLM training data or brittle web search.
This is the changelog for v2026-02-01, which contains breaking changes.
We are deprecating new_ein_issued and have deprecated state_tax.nm_complete_unemployment_reg, as previously messaged directly.
You can now schedule effective-dated benefit deductions and contributions directly on external employee benefits. This enables accurate, auditable benefit changes over time—reducing manual work, payroll-time fixes, and partner-side scheduling logic.
We now support time off policy management through a new time_off_management flow type.
Added company.marked_as_high_risk_business and company.marked_as_marijuana_business webhooks. These are emitted, respectively, when a company has been flagged by Gusto as being a high risk for fraud, or as being marijuana-related business.
