Calculation of income for purpose of filing return

My query is related to calculation of Income for the purpose of filing the Income Tax Returns: Assume that my gross salary is INR 10,00,000/- (ten lakhs only) My company has delayed the salaries and has only paid me salaries for 6 months. However when issuing Form-16 they have shown entire 10 lakhs as paid and also paid the taxes for the same. The calculation of tax is correct. Now what should I be showing as my income for the current year? Should I show it as 10 lakhs and show zero tax payable/refundable? Or Should I show my income is 5 lakhs and claim the tax refund for the balance 5 lakhs? My concern is that when I get paid the balance 5 lakhs in the next financial year I should not be charged tax for the same again? Then I would have to go through the entire process of justifying the calculation. Any guidance will be highly appreciated. Thanks,
