Ag Valuation
Agricultural Valuation Can Sharply Lower Rural Property Taxes
Land used for farming or ranching in Williamson County can be taxed on its productivity value rather than market value, which is usually much lower.
Texas law lets qualifying rural land be appraised at what it can produce — not what it could sell for. In a fast-growing county like Williamson, that difference can be enormous. To qualify, the land must have been used principally for agriculture for five of the seven years before you apply. WCAD requires a minimum of two animal units to qualify for livestock operations.
If land loses its ag status, the owner owes a rollback tax — the difference between ag-rate taxes and market-rate taxes for each of the previous three years plus interest. Before buying rural land, ask whether it has an ag valuation and what happens if you change how you use it. Apply through WCAD at wcad.org.
