The share of the same had stood at 53.9 per cent in 2011-12.
According to Ghosh, many measures since the note-ban in November 2016 have accelerated digitisation of the economy, and the pandemic-induced emergence of the gig economy has facilitated higher formalisation of the economy, at rates possibly much faster than most other nations.
The note ban hit hardest the informal sector which then constituted 93 per cent of the workforce. The second blow to the informal economy was the GST and the final and the hardest hit came from the pandemic.
At least Rs 13 lakh crore has come under the formal economy through various channels over the past few years, including the recent scheme on the E-Shram portal, the report said.
Real GDP was estimated at Rs 135.13 lakh crore in FY21 but lost 7.3 per cent of that in FY22 after the worst economic contraction on record due to the pandemic.
