The officials inspected laptops of Lenovo employees during the visit, one of the sources said.
They also tried to contact Lenovo's senior management during and after the visit as part of the inquiry, the person added.
Lenovo, which confirmed the visit, said it was "co-operating with the authorities and will provide all possible support required".
Earlier in the day, Reuters reported that tax officers also visited the facilities of contract manufacturer Flex Ltd in Tamil Nadu state.
