Intimation u/s 143(1)

Hello, I have received an intimation u/s 143(1). However, there is no tax payable or refundable as per the initimation. I also didn't file any loss.

So, I am not sure that why I have received the same because generally the acknowledgement of the return filed u/s 139 is deemed to be an initimation if no tax payable or refundable exists.

Please provide your inputs.

Thanks!
