India needs to pump in huge amount of funds in sectors like health, education, rural infrastructure and irrigation, he said at the launch of a book, 'India Transformed - 25 Years of Economic Reform' here.
The BJP-led NDA government has introduced a slew of reforms on various fronts like financial inclusion, foreign direct investment and big push to digital economy.
"There's no finishing line as far as reforms are concerned and I think India still has to cover a huge distance," Jaitley said.
He further said that given the more favourable global environment, India needs to improve upon its growth rate.

The high growth rate, he said, has to sustained over a reasonably long period of time "because you still have large number of people living below the poverty line, you still have infrastructure deficit, you still need a lot of investment in health, education, in rural India and irrigation".
Jaitley further said that unquestionably, 1991 was a key defining moment as far as India is concerned.
"Defining because it not only changed economic course, it changed the mindset of people," the finance minister said.
India has witnessed on an average 7 per cent growth in the past 25 years, he added.
Unquestionably, he said, India is a much better place to live in but added that still there are areas of challenges.
Singh, also Prime Minister of the country for 10 years, was also present at the book launch.
