Tricky - Status changed from NRI to Resident Indian

Hi, I have been living in UAE since 2013 and now going back to India permanently in Jun 2017. I have seen many threads regarding how the residency status can be calculated and I know that I would be resident indian after going back. My question which is unanswered in almost all the websites is how to calculate the taxable income. Let us say I earned 60000 AED as my salary (From April 2017 to June 2017) and 20000 AED as my End Of Service, so total money earned 80000 AED and based on my monthly expenditure I spent 20000 AED so total balanced is 60000 AED which I am remitting to my NRE account @17.5 (today's exchange rate AED to INR) so total money in my NRE account transferred in this financial year is 1050000 INR. Now I need to know that 1050000 INR is taxable or 1400000 INR (which is 80000 AED * 17.5) is taxable, and what would be the tax slab for that and how can I pay that tax and what is the cut-off date. What is the proof of earning and is it required to show or whatever I declare will be assumed as true. Thanks in advance.
