During Question Hour, Thakur also said that a number of steps are being taken by the government to strengthen the economy that includes merger of banks and tax concessions to industries.
"There is no 5 per cent slump. Where did you get the figure. Show us," he countered when Aam Aadmi Party MP Bhagwant Mann said the country is facing slump in the economy.
The Union minister of state for finance said India continues to the fastest growing economy in the world even though many countries in the world are facing economic slowdown.
"By 2025, India will be a five trillion dollars economy," he said.
Highlighting series of steps taken by the government to strengthen the economy, Thakur said tax concessions have been given to industries, foreign direct investments and MSME sector.
The minister said several banks have been merged with bigger banks and ultimate aim of the government is to keep four strong banks with solid footing and ensure increased economic activities.
He said strong actions have been taken against blackmoney and number of tax payers has been doubled due to demonetisation and implementation of the GST regime.
Thakur said as per the National Statistical Office (NSO), the GDP growth on average was 7.5 per cent in 2014-19, which is the highest amongst G-20 countries.
He said the World Economic Outlook (WEO) of October 2019, projects a significant slowdown in world output and trade in 2019.
"Yet India, despite some recent deceleration of GDP growth, is still projected by WEO to grow at the fastest rate in 2019-20 among G-20 countries," he said.
The minister said the government has been taking several measures to address moderate levels of fixed investment rate in the economy, plateauing of private consumption rate and a modest export performance, with a view to increasing the GDP growth of the country.
Thakur said in the last five years, the government implemented major reforms to build the investment climate in the country for becoming a US 5 trillion-dollar economy.
He said introduction of Insolvency and Bankruptcy Code (IBC) in 2016 is a significant step towards cleaning and strengthening of the financial system of the country.
Implementation of Goods and Services Tax in 2017 stands out as the most important measure for improving ease of doing business in the country and Make-in-India programme is a major initiative towards increasing the indigenous capacity of the country to produce world class goods and services, he said.
Thakur said continuous liberalisation has resulted in record and unprecedented inflows of foreign direct investment into the country and all along the government has kept inflation low, fiscal spending disciplined and current account deficit manageable to ensure macroeconomic stability to sustain a healthy investment climate in the country.
"More recently government has cut corporate tax rate from 30 per cent to 22 per cent to boost investment activity in the country. In particular, the corporate tax rate has been cut to 15 per cent for new domestic manufacturing companies which is amongst the lowest in the world," he said.
Thakur said one of the objectives of GST is to make India a common market with a view to sustaining a high level of GDP growth in the country.
Further, in the World Bank's Ease of Doing Business 2020 Report, India's ranking improved by 14 positions to 63 in 2019 from 77 in 2018 after GST was implemented in 2017, he said.
