Sir was incorporated into the Ottoman Empire in 1517 with all of Palestine, and in 1596 it appeared in the tax registers as being in the Nahiya of Bani Sa'b of the Liwa of Nablus. It had a population of 10 households, all Muslim. The villagers paid a fixed tax-rate of 33,3% on agricultural products, including wheat, barley, summer crops, olive trees, occasional revenues, goats and/or beehives, and a customary tax on subjects in Nablus region; a total of 7,000 Akçe. Half of the revenue went to a Waqf.
In 1882 the Palestine Exploration Fund's Survey of Western Palestine (SWP) noted at Khurbet Sir: "two rock cut tombs, a large mound with terraces cut in the sides, a good well below; has every appearance of an ancient site."
