Note that I didn't pay PG charges since I used DC. PG charges apply in the tax portal for CC.I use Cred, Cheq, PayTM for paying CC bills by DC. You can try and let us know if it is rewarding.
BTW, IDFC wealth DC reward rate is not on the same lines with IDFC wealth CC.
For IDFC wealth DC, points earned are per 150rs.
So, for online 4x rewards upto 50K and 10x later on. means
4x = 4*0.25*100/150 = 0.66%
10x = 10*0.25*100/150 = 1.66%
Whereas for wealth CC it would be 1.5% till 30K and 2.5% later on.
