The nave, chancel and apse are thought to date from the 1100s or early 1200s, making Tofta one of the older church buildings in the area. The vaulted ceiling was added in the 1400s, and the tower took its present form in the 1600s. The current east apse was rebuilt in 1787 on the foundations of the original. Notably, the church has never been extended with a transept, which helps preserve its ancient, single-volume medieval character.
The surrounding village retains some pre-enclosure character, with farms clustered south of the old road, several still with nineteenth-century outbuildings, and the old village track remains unpaved gravel. Archaeological finds from the Stone Age are said to have been discovered close to the church, pointing to a long history of settlement in the surrounding landscape.
The interior reflects two major nineteenth and early twentieth-century campaigns of renovation, by Carl Georg Brunius in the 1840s and by Wahlström around the turn of the twentieth century. Brunius, who also removed the southern porch and renewed the roof structure, left behind a communion rail and pulpit that are said to form a skilfully unified composition; the pulpit survives intact since its installation in 1846, made to his designs. From Wahlström's later work come the font, pew furnishings, organ gallery and hymn number board, forming a coherent ensemble typical of church interiors from that period, though decorative wall paintings from the same era were plastered over in the 1920s.
Among the church's furnishings is a triumphal crucifix dating from the late 1400s, and an altarpiece from the 1830s signed in Paris by Alexander Malmquist. The wooden font seen today was made in 1900. The nave still lacks electric lighting, relying instead on candles in chandeliers, wall sconces and candle stands, which adds to the building's old-fashioned atmosphere.
The church's organ has a layered history: an instrument built in 1763 by Christian Fredrik Hardt of Malmö was moved here from Asmundtorp church in 1846, replaced by an eight-stop organ from Åkerman & Lund in 1897, and succeeded in turn by the present ten-stop mechanical organ, built in 1971 by A. Mårtensson's orgelfabrik and housed within an older case front.
