Australia Tax File Number View

AustraliaTaxFileNumberView is a headless read-only display of Australia's Tax File Number (TFN), Australia's government-issued personal identifier. It renders as a <span> with an accessible label. It is the read-only companion to AustraliaTaxFileNumberInput.

Status: beta — implemented and unit-tested in all seven frameworks; not yet exercised in a composed flow.

Props

  • value: string (default: "") — the identifier to display
  • label: string (required) — accessible label via aria-label
  • ...restProps: any — additional HTML attributes spread onto the <span>

ARIA

  • aria-label={label} — provides the accessible name

When to Use

  • Use to display a stored Australia Tax File Number (TFN) read-only.
  • Use in summary lists, patient records, audit logs, or detail views.
  • Use when the identifier should not be editable in the current context.

When Not to Use

  • Do not use for editing identifiers — use australia-tax-file-number-input instead.
  • Do not use for general text display — use a <span> directly.
  • Do not use for other countries' identifiers — use the corresponding country-specific view.

Headless

This headless component ships zero CSS. The consumer provides all styling targeting the .australia-tax-file-number-view class hook.

Testing

  • Verify renders a <span> with the correct class
  • Verify the value prop is rendered as text content
  • Verify aria-label is set from the label prop
