Thailand won six gold, six silver and six bronze medals at the 2016 Paralympics in Rio de Janeiro earlier this month.
They were 23rd in the medal standings among 159 participating nations.
It was the country’s most successful Paralympic campaign since the Kingdom first took part in the Games in 1984.
The gold medals in Rio were won by wheelchair racers Pongsakorn Poyae and Prawat Wahoram, the boccia team and boccia star Watcharaphon Vongsa.
Pongsakorn, Prawat and Watcharaphon each got two gold medals.
Pongsakorn, 19, was the most successful Thai athlete in Rio as he also took home two silvers.
Under the National Sports Development Fund's bonus scheme for Paralympic athletes, a gold medal is worth B7.2 million, a silver B4.8mn and a bronze three million baht.
The associations and coaches of the medallists also get separate rewards.
According to the Paralympic Committee of Thailand, the government will also give unsuccessful athletes B100,000 each.
There were 45 Thai athletes at the Rio Paralympics and the government will have to pay out approximately B180mn in total.
