Sole Proprietorship - Moving Funds from Current Account to Personal Account for Interest Income

I am a sole Proprietorship with GST. All of my business income is received in my current account. I generally have expenses at end of year and not too much in between. Hardly 20-30 entries in personal account for entire year.

I have been moving my funds from current account to my personal account so that I can get saving account interest which is very beneficial for me.

Hence I had two queries:

1. For sole proprietorship, is this kind of setup allowed? Will it create issues for me in the future?

2. I pay tax through my personal account debit card which gives me decent points. Is this fine?
