Income tax demand - intimation 143(1) of less than inr 100

Hi

I have received a demand of income tax of INR 10/- under INTIMATION U/S 143 (1) OF THE INCOME TAX ACT after e-filing tax using ITR preparation utility from income tax website. This seems to be the rounding logic difference in utility and the computation at CPC end.

See screenshots below for details.

My queries are:

1) How do I pay this tax online? usine 280? which head? Where to fill Demand Identification number?

2) Can I raise this issue as the error at their end?

3) For tax demand of less than INR 100/- there seems to be special treatment? Do I need to pay this tax demand then?

Quick help is appreciated as the deadline of 30 days to pay is nearning.

Regards

Comp
