Tingsås began as a chapel community carved out of the neighbouring Väckelsång parish in the late 1500s, gradually gaining independence: a resident priest arrived in the 1690s, and full status as its own parish with its own rector followed in 1877. The two parishes were later reunited in a shared pastorate in 1992, with Tingsås as the leading congregation, and since 2010 the wider Tingsryd pastorate has brought together seven local parishes.
The present building, in a restrained neoclassical style with a rectangular nave, straight-ended chancel, sacristy and south tower, was built in 1853–1854 to a design credited to the builder Sven Nilsson, reworked by the architect Johan Fredrik Åbom. It was consecrated on Michaelmas Day, 5 October 1856, by Bishop Christopher Isac Heurlin. It replaced two earlier wooden churches on or near the site, the first raised in the 1590s and a larger one in 1752; the old churchyard lay a little to the north of today's building.
Two bells recall that earlier history: a small bell cast in 1595 survived from the first church, while the larger bell, cast in 1732, was later recast after cracking and still rings for services alongside its older companion. A medieval prime bell, of uncertain age, is now used at baptisms.
The chancel wall was reorganised in 1885 with painted panels by Bengt Nordenberg, whose altarpiece depicts the Transfiguration; the same artist contributed grisaille figures of Moses and the evangelist John. The earlier altarpiece from the 1752 church, showing the Last Supper and painted by Johannes Lundberg after the old altarpiece in Växjö Cathedral, has been retained and given a place of honour on a side wall. The sandstone font dates from 1931, and a free-standing baptismal tree was added in 2007.
Other furnishings include a longcase clock from 1778, reportedly a gift from local farmhands, and two large carved candelabra by Allan Jäderås from 1953. A small museum of older church items has been arranged in the roof space above the sacristy, historically shown only by arrangement. The current organ, built by Olof Hammarberg of Gothenburg and installed in 1970, retains the façade of an earlier 1864 instrument by Frans Andersson; a smaller mechanical chancel organ was added in 1967.
