His highest attested year is a year 18. It is sometimes derived from the combination of two letters found in el-Hiba, the first mentioning an untitled Masaharta praying for his health, and the second a letter of thanks to the local god by the High Priest Menkheperre, that Masaharta died of illness at el-Hiba around the 24th regnal year of Smendes, but this is no more than an unproven hypothesis. In fact, it has been pointed out that such a scenario ill fits the content of the letters.
