With this, the hill state will become the fourth after Assam, Bihar and Jharkhand to ratify the bill.
"The constitution amendment bill on GST will be tabled in the assembly," S.S. Verma, Secretary to the Speaker, told IANS.
The six-day session will have five sittings, with a holiday on August 26. It will conclude on August 27.
Chief Minister Virbhadra Singh has hailed the passage of the bill in parliament, saying it was the previous Congress-led United Progressive Alliance (UPA) government that conceived the measure.
"The Congress was in favour of the bill," the Chief Minister told reporters here, adding "In fact, the UPA government had brought this bill."
Political observers said the GST bill was likely to be passed unanimously as in the 68-member assembly, where the Congress has a majority with 36 members. The Bharatiya Janata Party (BJP) has 27 legislators.
There are four independent legislators and one from the Himachal Lok Shakti Party, which has been merged with the BJP.
The four independent legislators are associate members of the Congress.
Official sources said the government, during the session, would also bring an amendment to regulate the sale of cigarettes and tobacco products.
The Town and Country Planning (Amendment) Bill will also be tabled to pave the way for regularising unauthorised buildings -- believed to over 25,000 -- across the state.
The bill will replace an ordinance.
