# Update an employee's tax card

`PATCH /payroll/employees/tax-card`

## Request

- Base URL: `https://api.app.lastaccountingcompany.com/portal`
- URL: `https://api.app.lastaccountingcompany.com/portal/payroll/employees/tax-card`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/lastaccountingcompany/apis/lac-customer-api/docs/payroll/employees/tax-card/patch.ts> (a function with typed inputs; its response is checked against the schema)

NOT available to API keys — requires an interactive admin/approver session. Updates the withholding tax-card values for one employee: base and additional withholding rates in basis points, income ceiling in integer cents, effective-from date, and prior year-to-date gross in cents.

## Request body

- object
  - `customer_id` string: Target company. Optional for API keys.
  - `period` string: Payroll period, `YYYY-MM`.
  - `employee_id` string, required
  - `contract_id` string
  - `withholding_basis_points` integer: Base withholding rate in basis points.
  - `tax_card_additional_basis_points` integer: Additional withholding rate in basis points.
  - `tax_card_income_ceiling_cents` integer: Tax-card income ceiling in integer cents.
  - `tax_card_effective_from` string: Effective-from date, `YYYY-MM-DD`.
  - `tax_card_prior_ytd_gross_cents` integer: Prior year-to-date gross earnings in integer cents.

## Response `200`

Updated payroll workspace.

- PayrollWorkspaceData: The payroll workspace for a period: employees, employer settings, and runs. Amounts are integer cents; rates are basis points. Interior shapes beyond the top level vary and are returned as-is.

## Other responses

- `401`: Missing or invalid bearer token.
- `403`: Insufficient scope or role — e.g. a read-scoped key on a mutating method, or an API key on an admin/approver-only endpoint.
