The most significant impact of the lower rates under GST has been the increase in collections, also from direct taxes, which will permit further rationalising of the rates under the new indirect tax regime, Finance Minister Arun Jaitley said on Sunday.

In a video address shown at an event here to mark the first anniversary of the roll out of the Goods and Services Tax (GST), Jaitley said that with the input tax credit mechanism ensuring that proper disclosures are made even of income tax, direct tax collections were showing a rise.
