# Update an employee's tax card

`PATCH /payroll/employees/tax-card`

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.
