Please tell me in Gst tax applicable on jobwork. If applicable then what rate of tax

For AY 2016-17, I paid TDS of Rs.86995.00 and self assessment tax of Rs.7767.00. But in the assessment order under 143(1) the IT dept. did not account for the self assessment tax and demanded tax of Rs.7450 on 28.05.2017. The self assessment tax is reflected in 26AS. I filed rectification return on the same date.
Even in the rectification order under 154 issued on 22.06.2017, they have demanded tax again, this time together with interest under 234B and 234C. I will have to file rectification return again, but will that be enough? What might be the reason for the mismatch? Please take note that self assessment tax was paid online and challan copy is available with me.

I gave an advance towards purchase of property to a company in 2012. Due to legal issues on land, project never completed. Developer is not returning money. Instead he is willing to register similarly priced plot in another project under different company. Only one partner is common between these 2 companies with whom I am talking. There are different partners though minor share. He says it's OK to mention the old check number issued in 2012 in sale deed. Is it OK? any issues legally from ownership point of view and tax point of view
