The traders' body made the plea at a conference held in Odisha last week.
"More than 150 trade leaders of 24 states at a traders conference in Odisha in a unanimous voice has urged the political parties not to play political innings on GST," CAIT said in a statement.
It felt that implementation of GST would lead to ease in doing business and abolish "the colonial working" of the tax administration system.
"It is high time a consensus was evolved among political parties to ensure safe and smooth passage of this economic reform," it said.
Indirect tax reform GST proposes to create a uniform tax rate across the country by subsuming excise, service tax and other local levies. This is estimated to boost India's GDP by 1-2 per cent.
The government has proposed to introduce the new structure from April 1, 2016.
