Update: Dayforce MCP tools for Claude integration

We’ve published an updated set of Dayforce MCP tools related to Payroll Tax Engine Tools for use with the Anthropic Claude connector. This update extends from the previously posted article as linked below.

Payroll Tax Engine Tools

Read access to statutory payroll tax rates and limits, legal entity tax rate overrides, supplemental withholding methods, compensation and benefits limits, and SUI results from the last committed pay run.

Tool

Description

payroll_tax.tax_engine.tax_rates_and_limits.get

(Get tax rates and limits)

Returns USA payroll tax rates and limits for a state from the Tax Engine reference data, including the tax name, tax code, rates, and wage-base limits. Use it to look up the published statutory rates and limits for a state and, optionally, a locality. Results cover reference rates only; they are not specific to any legal entity or pay run.

payroll_tax.tax_engine.legal_entity_payroll_tax_rates.get

(Get legal entity payroll tax rates)

Returns the USA experience (SUI) tax rates configured for the organization's legal entities, effective as of a given date. Each record includes the legal entity, payroll tax, rate, and effective dates. Use it to review the employer-specific tax rates in effect on a particular date.

payroll_tax.tax_engine.last_pay_run_sui_taxes.get

(Get last pay run SUI tax rates)

Returns the State Unemployment Insurance (SUI) tax rates from the most recently committed pay run for a given USA state. Use it to review the SUI rates that were applied in the last committed pay run for that state.

payroll_tax.tax_engine.last_pay_run_sui_excluded_employees.get

(Get employees missing from last pay run SUI calculation)

Returns employees who were not included in the State Unemployment Insurance (SUI) calculation of the most recently committed pay run for a given USA state, along with their SUI tax information. Use it to identify employees excluded from the last committed pay run's SUI calculation for that state.

payroll_tax.tax_engine.supplemental_tax_rates.get

(Get supplemental tax rates)

Returns the USA supplemental wage withholding methods for a given state from the Tax Engine reference data, including the state's default method and, for each available method, the supplemental code, rate, wage limits, effective dates, and calculation notes. Use it to look up how supplemental wages such as bonuses and commissions are taxed in a state. Results cover reference rates only; they are not specific to any legal entity, employee, or pay run.

payroll_tax.tax_engine.compensation_benefits_limits.get

(Get compensation and benefits limits)

Returns the USA compensation and benefits limits from the Tax Engine reference data, effective as of a given date. Each record includes the tax method, limit type, limit option, limit amount (with Puerto Rico amounts where applicable), any qualifying criteria or age, and effective dates. Use it to look up statutory limits, such as retirement plan contribution and catch-up limits, in effect on a particular date. Results cover reference limits only; they are not specific to any legal entity, employee, or pay run.

Thanks for the update. These six tools cover US payroll tax only. Are Canadian payroll tools on the roadmap, for example CPP/QPP, EI, QPIP, and T4/RL-1 box mapping? Thanks!
