In financial accounting for the purpose of calculation and accounting, we take into consideration, financial/fiscal year and not the calendar year. The fiscal/ Financial year starts from the 1st of April and ends on the 31st of March. Therefore, as per the above question salary of MR. X for PY 2019-2020 will be calculated as follows. He joins the job on 1-July-2019 and the year ends on 31st March 2020 so total months in PY for which salary is payable to MR. X comes to 9 months. Therefore Salary of MR. X will be Rs. 30,000 x 9 months = Rs. 2,70,000.
