Gusto

Gusto is an all-in-one payroll and HR platform serving more than 500,000 businesses across the United States. Headquartered in San Francisco, Gusto automates the complex tasks of running payroll, administering employee benefits, and maintaining compliance with federal and state tax regulations. Payroll: Gusto runs full-service payroll in minutes, calculating and filing federal and state taxes automatically, depositing funds via direct deposit or paper check, and paying contractors and 1099 workers. The platform tracks gross and net pay, tax withholdings, and pay period history per employee. It also identifies eligible tax credits, including R&D credits, to reduce tax liability. Benefits Administration: Employers can compare and enroll employees in medical, dental, and vision plans from top carriers. Gusto also manages 401(k), HSA, FSA, commuter benefits, life and disability insurance, and workers' compensation. Enrollment status and coverage details are accessible per employee. HR and Onboarding: Features include digital offer letters, new-hire onboarding checklists, employee self-service portals, PTO policy setup and balance tracking, time and attendance logging, talent management, performance tracking, and an HR document library (offer letters, W-2s, 1099s). Compliance: Gusto automatically generates and files W-2s and 1099s at year-end, handles state new-hire reporting, registers businesses in new states, and surfaces compliance alerts for changing regulations. MCP Integration: The Gusto MCP server at https://mcp.api.gusto.com enables AI assistants to look up payroll run history with gross and net amounts and tax withholdings, retrieve employee records (start date, compensation, status, manager), query benefits enrollment (health plans, 401(k), HSA/FSA), check tax filings and payments, review time-tracking entries and PTO balances, access contractor payment history and 1099 data, and retrieve HR documents. Queries can be filtered by employee, pay period, or filing date. An active account is required to use this app. Available in Microsoft 365 Copilot. A Gusto account is required.
