## When to prefer this

Use this endpoint when you need the full chronological history of South African income tax bracket structures — for example, to chart how tax rates have evolved across budget years, to verify what rates applied in a specific past tax year, or to build a time-aware tax calculation engine. Prefer this over the current-snapshot endpoint when historical comparison or trend analysis is required.
