Income from India Taxation

I have a client from India who pays monthly salary to me, not directly, rather to my company registered in Nepal and I take as a normal salary from my Nepal company. But this leads to double taxation.
First, while transferring from Indian company to Nepal company, 20.8% GST is deducted in India.
Second, the normal income tax in Nepal which reach up to 36%.

Is there any way to minimize taxes? They are open to transfer directly to my personal account as well.
Anyone knows whether that 20.8% can be wived off if they pay me directly? And also, will I be paying just 5% flat in this scenario?
