HOW TO PREPARE FOR IT WHAT TO REFER LIKE ONLINE CLASSES OR NOTES, ANY HELP

We are in the business of erection of buildings, We often receive invoices in the month of April and May which are having dates of April and May but in the Description of Service they mention crane charges for the month of Jan, Feb and March. Till now we were making provision for it and deducting TDS. Now the party is telling that since they have issued bill in april and they have considered it as income of next financial year, we should deduct TDS in current Financial year. We are also claiming GST in April only when we receive the bills.
My question is if we book the expenses in April or May the month in which bill is issued. Will the department not qualify it as prior period expenditure, since in the narration it is written Feb and March Expenses.

At the time of registering a property, the valuation for the purpose of stamp duty is found to be higher than transaction value.
Will the additional valuation be treated as deemed income in the hands of seller?
What is the relevant income tax provision?

Esteemed members,

I am employed in Saudi Arabia since 2019. Since 1st April in this FY, I am in India. My contract with my Saudi employer expires on 31 July 2021. Assuming that I travel to Saudi on 1st June 2021, my total stay in Saudi will only be 2 months. My question is that if I still remain outside of India somehow for another 4 months (in bits and pieces) without a foreign job, will I be considered as an NRI for 2021-22 FY? Many thanks in advance!
